（23-24高一上·福建·期末）Thanks to its proximity (邻近) to England, its successful tourism industry and
its multicultural population, Edinburgh is quite a special city in Scotland.
Edinburgh simply makes it with culture during its long holiday season. It is not just its famous festivals in the
summer but its Christmas and Hogmanay (除夕) celebrations, which fill the city with tourists from all over the world.
Along with the tourists, Edinburgh has lots of students. They bring energy and variety to the culture of the city.
Although this can be overwhelming (令人不知所措) at times, if you open your arms to the good that it brings you
can get so much out of the city.
The Cycling Gardeners are a part of the local community. By being totally dependent on bikes for transport,
we are limited to working within the city centre. We have made life a bit easier on ourselves by using electric bikes,
and we often beat cars in traffic and have no problem finding place to park.
We have a great collective team spirit which is very important. Whenever you go there from May to September,
you will likely meet both sunshine and rain. But the wet weather can be dealt with by helping each other out, spending
time in the many local cafes, catching up with your friends and having a good discussion about the rain!
Without doubt my favourite place in Edinburgh is the Meadows Park. I was born in the hospital overlooking
it and grew up in buildings around it. Much of my childhood days were spent there. I met my wife there and it is
where I take my young son to play. I have the happiest memories of building snowmen when the snow comes down. I
really hope that this winter brings good snow so I can review my own childhood with my son!
1．What does Edinburgh attract visitors most?
A．Its successful industry. B．Its famous festivals.
C．Its rainy seasons. D．Its beautiful view.
2．Compared with driving cars, what’s the advantages of riding electric bikes for Cycling Gardeners?
A．Speed. B．Comfort.
C．Convenience. D．Expense.
3．What does the underlined phrase “catching up” in paragraph 4 mean?
A．Getting up. B．Meeting up.
C．Showing up. D．Picking up.
4．Why is the Meadows Park the author’s favorite place in Edinburgh?
学科网（北京）股份有限公司A．He has good memories there. B．He was born there.
C．He played with his young son there. D．He met his wife there.
（23-24高一上·福建·期末）Roadkill is a worldwide problem. Every year: About 340 million birds are killed
on roads in the United States; around 9 million mammals (哺乳动物) of average size are killed on Brazilian roads;
and China is no exception.
To deal with this, a study of “roadkill” has been conducted by Professor Li Zhongqiu and his team from
Nanjing University. The study was conducted in Nanjing, which has more than 9,700 km of well-built roads. Li and
his teammates ran 26 roadkill monitoring (监测) activities over 224.27 km of roads, totaling 5,831 km during the
research period. The nine roads chosen for the team’s research were monitored every two weeks over the course of a year.
The team recorded a total of 293 dead bodies. Among them, birds made up nearly half the total. As a main bird
species in East China, blackbirds are usually attracted by flies or other insects to dead bodies of roadkill along the
roads. “Specifically, cats, dogs and blackbirds were the three most commonly killed animals,” Li said. “This may be
due to the large number of homeless cats and dogs in city areas. Pets thrown out of their homes are more likely to run
into traffic.”
According to the report, roadkill happened a lot from May to September. The animal’ increased reproductive
(生殖) activity in summer and autumn is a possible reason. Besides, roadkill issues also topped in November and
January. This may be due to the need to search for food during winter when food resources are few, Li said.
“There is no doubt that roadkill has contributed to the decrease of animal populations and must be taken
seriously,” Li said. “We call on related departments to take measures such as speed limits and necessary traffic
controls during top periods of animal activities. For animals such as cats and dogs that usually use the roads, fences
can prevent them from entering traffic.”
1．What is paragraph 1 of the text mainly about?
A．The purpose of the study. B．The method of the study.
C．The result of the study. D．The background of the study.
2．How often were the chosen roads monitored during a research year?
A．Once every two weeks. B．Once a week.
C．Three times every two weeks. D．Twice a week.
3．What is the possible reason why roadkill accidents happen the most in November and January?
A．Large animal birth rate. B．Busier traffic.
学科网（北京）股份有限公司C．Few traffic controls. D．Animals’ demand for food.
4．What can policymakers do to reduce cat roadkill incidents according to Professor Li?
A．Having speed limits. B．Taking traffic controls.
C．Building fences. D．Setting warning signs.
（23-24高一上·甘肃庆阳·期末）Rivers are very important. Humans rely on them for food and water. But
rivers can destroy things, too. They can flood, or rise over their banks, making the water run into the nearby land.
Floods can also kill humans and wildlife. However, floods are not always bad. Some ecosystems need them every
once in a while.
Flooding can not only drown animals but also destroy habitats. For example, a flood in India in 2012 killed
many one-horned rhinos. Flood waters can pick up dirt from riverbanks, which makes the water dirty. Too much dirt
will clog rivers and streams, preventing the river from flowing. Sometimes flood waters can carry pollution to the
sea and harm marine life. In addition, flood waters can carry disease, including hepatitis A (甲型肝炎) and cholera
(霍乱).
However, not everything about floods is bad. Sometimes they bring new life to ecosystems. Flood waters carry
nutrients to the nearby land. Over time, the water dries up and leaves behind particles (微粒) of dirt and mud. The
particles are called sediment (沉淀物) which can be good due to its ability to improve the dirt and help plants grow.
Floods are important to some animals as well. For instance, some animals see floods as a sign that it is time to mate
or migrate. Floods leave sediment on river beds where baby fish can grow and carry nutrients for small animals in
the water to eat. Moreover, in dry seasons, water might dry up, but floods help refill the wetlands, keeping the
ecosystem going.
Floods are a part of nature. They can destroy living things and the environment. But some ecosystems need
floods to survive.
1．What’s the possible meaning of the underlined word “clog” in Paragraph 2?
A．Become. B．Pollute. C．Block. D．Develop.
2．How do floods help ecosystems?
A．Nutrients carried by floods can make soil richer.
B．Floods make all the animals migrate more easily.
C．Tiny fish going with floods feed some animals.
D．Floods can improve the dirt and help plants grow.
3．What’s the main idea of Paragraph 3?
学科网（北京）股份有限公司A．The way in which floods feed animals. B．The benefits of floods to ecosystems.
C．An effective means of improving soil. D．The reason for people’s appreciating floods.
4．What’s the best title of this article?
A．The Bad Effects of Flooding B．The Secret of Flooding
C．Floods-A Disaster to Humans D．Floods — A Part of Nature
（23-24高一上·江苏泰州·期末）Those of us who shop online may scan customer reviews to get a better
sense of products we can't judge for ourselves at a physical store. We may check out online testimonials before
booking a haircut or visiting a new restaurant. But what happens if some of those reviews can't be trusted?
The Federal Trade Commission (FTC) recently announced that it was proposing new measures to crack down
on fake reviews and other practices used to mislead consumers. The commission published a proposed rule that would
prohibit companies from writing or selling fake reviews, buying positive reviews, suppressing negative reviews and
more.
“Our proposed rule on fake reviews shows that we're using all available means to attack deceptive advertising in
the digital age,” Samuel Levine, director of the FTC's Bureau of Consumer Protection, said in a statement.
Research shows people overwhelmingly consult online reviews, but humans are also bad at telling which
consumer reviews hold water and which are nonsense.
That's potentially worrisome given that nearly one in every three reviews is fake, according to one estimate.
In arguing for the proposal, the FTC cited enforcement actions it had taken against companies that manipulated
reviews of their products.
In 2022, for example, the commission forced the online retailer Fashion Nova to pay $4.2 million to settle
allegations (指控) that it blocked negative reviews from being posted on its website — the first FTC action involving a
company's effort to hide negative reviews. For its part, Fashion Nova said in a statement to The New York Times that
the FTC's allegations were “inaccurate” and that it only settled the charges to avoid “the distraction and legal fees”.
Comments on the proposed rule have to be received within 60 days of its publication in the Federal Register,
after which the FTC will decide whether to issue a revised final version.
1．What is the main purpose of the FTC's proposed rule?
A．To improve the quality of products and services.
B．To protect the interests of physical stores.
C．To ban negative reviews from online platforms.
D．To ensure true reviews are presented to customers.
学科网（北京）股份有限公司2．What does the underlined phrase “hold water” in Paragraph 4 most probably mean?
A．Be credible. B．Be prejudiced. C．Be official. D．Be misleading.
3．Why was Fashion Nova forced to pay $ 4.2 million in a settlement in 2022?
A．To delete negative reviews of its products.
B．To post customer reviews on its website.
C．To resolve allegations of deceptive advertising.
D．To prevent it from facing further criticism and legal fees.
4．What can be inferred about the proposed rule?
A．It is well-received. B．It is still under review.
C．It has proven to be effective. D．It has encountered opposition.
（23-24高一上·广东惠州·期末）There are thousands of languages in the world. But which language is the
oldest? Experts use different methods to find out the age of a language.
Finding the oldest language is a challenging task, according to Danny Hieber, an expert in the study of endangered
languages. “If we think that most languages can date back to an original human language, all languages are equally
old,” Hieber said. However, it’s impossible to find out such language —the direct ancestor of every language in the
world. Accordingly, some experts believe that the “oldest language” should belong to one with a well-established
written record.
Many of the earliest recorded examples of writing come from languages that used cuneiform script (楔形文
字). Among these languages are Sumerian and Akkadian, both dating back at least 4,600 years. Experts have also
found Egyptian hieroglyphs that date to around the same historical period. These hieroglyphs, which can be translated
into “He has united the Two Lands for his son, Dual King Peribsen,” are considered the earliest complete sentence
ever discovered.
Experts generally agree that Sumerian, Akkadian and Egyptian are the oldest languages with a clear written
record. All three are extinct, meaning that they are no longer used and don’t have any living followers which can
carry the language to the next generation.
As for the oldest language that is still spoken, several competitors appear. Hebrew and Arabic stand out among
such languages for having timelines that experts can reasonably find, according to Hieber. Although these earliest
written languages only date back around 3,000 years, Hieber said, “both of them belong to the Afroasiatic language
family, whose roots date back to 18, 000 to 8,000 B．C． E. , or about 20,000 to 10,000 years ago.” Even with this
wide period of time, it is widely accepted that Afroasiatic is the oldest language family. But the exact point in time
学科网（北京）股份有限公司when Hebrew and Arabic separated from other Afroasiatic languages is heavily debated among experts.
1．How do experts determine the age of a language?
A．By studying its spoken dialects. B．By analyzing its basic grammar.
C．By examining its written records. D．By comparing it to other languages.
2．What is the value of the Egyptian hieroglyphs?
A．They’re an example of cuneiform script. B．They belong to the Afroasiatic language.
C．They provide evidence of the oldest language. D．They’re the earliest-known complete sentences.
3．What does the underlined word “extinct” in paragraph 4 mean?
A．Gone B．Ancient. C．Outdated. D．Active.
4．What is the main disagreement among experts regarding Hebrew and Arabic?
A．The reason for their standing out. B．The exact time of their separation.
C．The appearance of their competitors. D．The roots of earliest written languages.
（23-24高一上·广东茂名·期末）When you are a kid, gaining a best friend forever can happen in a single
play date. But when you grow up to be an adult, making and maintaining friendships gets harder. So how much
quality time (优质时光) do you need before that stranger becomes your friend? A new study recently found that, on
average, it takes about 50 hours with someone before you consider them a casual (感情不深的) friend, about 90
hours before you become real friends, and about 200 hours to become close friends.
The study’s author Jeffrey Hall, a communications professor, invited adults who are eager to make friends to
take part in two experiments — people who had just moved to a new city in the past six months and college freshmen.
He asked them to rate and track the degree of closeness and time spent together with a new person. “Results suggest
that the chance of changing from casual friend to real friend is greater than 50% after around 80-100 hours together,”
said Hall.
The study found that the amount of time spent talking together, or the fact that you spent time at school or
work with them, was unrelated to friendship closeness. “It is really easy to spend a lot of time with people as they
are routinely in the same place at the same time as you,” Hall said. “However, my study shows you can have
workmates you spend hundreds and hundreds of hours with and still not develop a friendship.”
You do not need to become best friends with your workmates to develop meaningful relationships with them.
But for those of us hoping to change from “girl who I eat lunch at work with” to “friend I can depend on,” Hall
suggests that you need to take the relationship out of the workplace for it to become a friendship. The participants
who did activities outside of work with someone, such as being invited to have lunch in their home, were more likely
学科网（北京）股份有限公司to develop deeper relationships with them.
1．What is the new study mainly about?
A．Ways of making friends in a new environment. B．Why people need to make different friends.
C．Different levels of friendship. D．How long it takes to develop a friendship.
2．What do we know about the participants in the study?
A．They knew each other before. B．They had difficulty in making new friends.
C．They were in great need of friends. D．They started their new life in the same city.
3．What does the underlined word “routinely” probably mean in paragraph 3?
A．Usually. B．Actively. C．Seldom. D．Confidently.
4．Which can help people build deeper relationships with workmates according to Hall?
A．Joining the same work team. B．Having lunch at work with them.
C．Inviting them to your home after work. D．Sharing work experience with each other.
（23-24高一上·浙江杭州·期末）Imagine if there were a robotic fish that filtered microplastic out of the
water as it swam. Well, now there is one, and it’s the physical version of the winning concept in the first-ever Natural
Robotics Contest.
Announced this May, the University of Surrey’s Natural Robots Contest invited members of the public to give
their concepts for animal—or plant-inspired robots capable of performing activities that would help the world.
Plans called for experts from various British and European research centers to select what they thought was
the best concept, which would then be made into a real robot. Engineers would proceed to further develop the
technology.
The winning concept turned out to be the plastic-collecting Robo-fish, designed by chemistry student Eleanor
Mackintosh—who is a University of Surrey student. Mackintosh said, “Fish’s gills are an incredible mechanism in
nature that are specialized to filter oxygen into the bloodstream—so I adapted my design from that, with the purpose of
dealing with the plastic pollution in the water.”
The robot swims by moving its tail, holding its mouth wide open to-collect water and microplastics in its belly
as it does so. Once that cavity is full, the robot closes its mouth, opens its gills, and pushes the water out through. A
fine net attached to the gill flaps allows the water to pass through, but captures the microplastic.
In its current physical form, the 50-cm-long Robo-fish collects microplastic as small as 2 millimeters. It also
uses sensors to monitor underwater environment, plus it tracks its movements within the water.
Future robots could capture much smaller particles. Other possible improvements include a faster body shape, a
学科网（北京）股份有限公司more powerful tail, and the ability to swim autonomously.
1．How do the participants attend the Natural Robotics Contest?
A．By handing in real robots. B．By sending the concepts of robots.
C．By selecting the best robot concepts. D．By developing the technology of robots.
2．What inspired Mackintosh to design the robot?
A．The enthusiasm for robots. B．The function of fish’s gills.
C．The body shape of the fish. D．The plastic pollution in the water.
3．What does the author intend to show in paragraph 5?
A．How the robotic fish works in water. B．How the robotic fish is further improved.
C．Why Mackintosh’s robot won the contest. D．What materials the robotic fish is made of.
4．What is the best title of the text?
A．The First Bio-Inspired Robotics ContestB．The One-Size-Fits-All Solution to Plastics
C．An Autonomously Operative Robotic Fish D．A Student-Designed Plastic-Collecting Fish
（23-24 高一上·浙江宁波·期末）Learning any language is hard, but learning English can be especially
challenging. Why? Because native speakers use the language in ways that textbooks could never describe. In particular,
words that British people use cause many language students to scratch their heads.
Here’s an example: You overhear a Briton calling someone a “wazzock”. But what exactly is a wazzock? This
word, in fact, means a foolish person, although there’s nothing about it that would help you guess that. There are
many strange terms like this in British English — the Oxford English Dictionary would be much smaller without
these odd usages filling its pages.
How can these odd words be explained? Part of the answer is the British sense of humor. Britons don’t like to
take things too seriously, and this is evident through many British words and phrases. For example, to “spend a
penny” means to use the bathroom. It refers to the days when people had to pay a penny to use a public toilet.
In an interview for the BBC’s website, British linguist David Crystal suggested there may be historical reasons
for the large number of odd words and phrases in British English. He thinks that they began in the late 16th and early
17th centuries. This was a great age for the theater, when Shakespear e and other writers worked hard to keep up with
the demand for new plays. The theater’s popularity also created an incentive to invent new words. With this in mind,
perhaps Shakespeare and his peers are to blame for unusual British words such as “codswallop” and “balderdash” —
which both, mean “nonsense”.
While these strange words may be confusing to non-native speakers, they certainly make studying English a lot
学科网（北京）股份有限公司more interesting.
1．According to the text, why may non-native speakers find it more challenging to learn English?
A．Dictionaries are too complicated to understand.
B．The English vocabulary is too large for them to learn.
C．A large number of strange expressions confuse them.
D．The English textbooks they use are usually out of date.
2．With the example of “the Oxford English Dictionary” in Paragraph 2, the author intends to .
A．stress the large number of strange terms
B．explain the origin of the strange phrases
C．show British people’s attitude towards odd phrases
D．show the usefulness of the Oxford English Dictionary
3．Which of the following words has the similar meaning to the underlined word “incentive” in Paragraph 4?
A．concern B．inspiration C．application D．opinion
4．What is the tone of the author in writing the article?
A．Aerious. B．Anxious. C．Indifferent. D．Humorous.
（23-24高一上·浙江杭州·期末）The public nowadays has a misunderstanding of forest fires, believing that
fires should be kept out of every type of forest. Many of us can recall Smokey the Bear’s famous warning: “Remember,
only YOU can prevent forest fires”. However, that’s not always the case. Under the right conditions, and when
conducted safely, fire can create many environmental benefits as well as help prevent larger, uncontrollable
wildfires.
After a forest fire, many wildlife species will move into recently burned areas to feed on these newly available
foods. Some reptiles and amphibians such as the snake prefer forests frequently burned by fire. As Herbert Stoddard
put it, “One of the most harmful things modern man has done to birds has been his attempt to exclude fire from
fire-type pine (松树) forests. Within a few years most forests choke up with bushes, lose their prairie-like
vegetation (草原般植被) and can no longer support birds which depend on periodic burning for their food supply
and proper cover.”
If you are asked to picture the forest floor, what do you see? Pine needles, cones, leaves, branches might come
to mind — all sources of fuel. If these fuel sources build up without any type of removal, the ‘fuel load’ can lead to
学科网（北京）股份有限公司fires which are huge disasters to forests and people alike. In contrast, prescribed fires can be used by forest
professionals every couple of years to keep forest fuels at a proper and manageable level. They can also greatly reduce
the spread of pest insects and disease and remove unwanted tree and plant species. Plus, they can create and maintain
important wildlife habitats rich in grasses and promote the growth of trees, wildflowers and other various plants.
Many organizations work to promote fire on the landscape. Smoky Bear even has an updated warning: “Only
YOU can prevent wildfires,” as the Forest Service has over the last few decades developed policies and measures to
include prescribed fire as a useful tool, as well as continuing their work to prevent and fight wildfires.
1．What can benefit birds according to Herbert Stoddard?
A．Forest bushes. B．Periodic burning.
C．Fuel sources. D．Pine forests.
2．What does the underlined word “prescribed” in paragraph 3 probably mean?
A．Frequent. B．Wild. C．Planned. D．Damaging.
3．Why do forest professionals need to conduct fire every couple of years according to the passage?
A．To keep the forest in balance. B．To keep the fuel rich in the forest.
C．To put out wildfires. D．To remove tree and plant species.
4．What is the author’s purpose in writing the text?
A．To prevent the use of prescribed fire in the forest.
B．To promote the complete exclusion of fire from forests.
C．To educate people on positive aspects of controlled fires.
D．To encourage the public to remove sources of forest fuels.
（23-24高一上·湖南衡阳·期末）For a century, Disney has captured the hearts and imaginations of millions
worldwide.
From a small animation (动画) studio to a global entertainment empire, Disney has created a miracle that has
lasted for generations.
Over the years, Disney has continued to push the boundaries of creativity and technology. Walt Disney, the
visionary founder, revolutionized (变革) the animation industry with the creation of Mickey MouseF in 1928,the
world’s first synchronized sound and color cartoon, setting the stage for the incredible journey that would follow. In
1937, Disney released the first-ever full-length animated feature film, Snow White and the Seven Dwarfs, establishing
Disney as a leader in animation. This breakthrough also paved the way for the future of storytelling in cinema,
including The Lion King and Frozen.
学科网（北京）股份有限公司However, Disney’s influence extends far beyond the silver screen. In 1955, the opening of Disneyland transformed
Disney from a successful animation studio to a global entertainment giant. It revolutionized the concept of family
entertainment and explored immersive theme park experiences by introducing the world to a magical kingdom where
dreams come true, solidifying Disney’s status as a leader in the entertainment industry. Moreover, Disney’s acquisition (
收购) of other entertainment companies, such as Pixar and Marvel, has allowed Disney to bring characters like Woody
and Buzz Lightyear, Iron Man and Captain America into its ever- expanding universe, connecting storylines and
experiences across multiple media, from films to television series to video games.
Walt Disney once said, “We keep moving forward, opening new doors, and doing new things,”and this spirit has
been the foundation of the company’s remarkable success. Disney’s story demonstrates the power of dreams, creativity,
and the belief that anything is possible. Nowadays, Disney has become the peak of success, a shining example of
what can be accomplished when imagination knows no bounds.

D．To prove the significance of imagination.
（23-24高一上·广东深圳·期末）In the continuing fever for outdoor sports and activities, China’s young
generation now find themselves drawn to a new activity—lure fishing (假饵钓鱼).
Traditional fishing methods use real bait (饵) and often require hours of patient waiting. However, lure fishing
学科网（北京）股份有限公司takes a different approach. Here, fishermen use man-made bait to copy the movements of a fish’s natural prey (捕
食) such as swimming, struggling and escaping. In this way, fish will mistake the bait for the real prey and make
attack. Because fishermen need to frequently throw and take back the line to seek for fish, the sport looks elegant and
is called “water golf”.
“The fish shakes and struggles sharply. The feeling is just like putting your hand out of the window while driving
at fifty miles per hour,” a fishing lover says, recalling his experience of catching a big fish using a lure fishing
technique.
In recent months, many young Chinese have taken to social media to share their experiences. The topic “lure
fishing” has over 140,000 posts on the lifestyle platform Xiaohongshu, and videos with the same tag have billions of
views on the short video platform Douyin.
Another feature that attracts the young generation is lure fishing’s environmentally-responsible approach. By
using green man-made bait, the activity does not bring trouble to the natural environment of the water. Also, the
general agreement in the lure fishing community is to “catch and release”, which is to let the little fish go and grow,
in order to protect fish.
Moreover, lure fishing is beginner-friendly and requires less equipment compared with traditional fishing. A
basic set costs between 500 and 2,000 yuan. But costs can rise significantly if you seek to take a more professional
approach.
“Each fishing scene has its fishing rod (竿), and each fishing technique also has its fishing rod,” another lure
fishing lover says. He adds he has seven to eight sets of fishing rods, which should come to thousands of yuan in
cost.
1．How is lure fishing different from traditional methods?
A．It is a more active way. B．It uses real small fish as bait.
C．It is a more time-consuming way. D．It saves fishing lovers’ energy.
2．Which of the following best describes the feeling of the lure fishing lover in paragraph 3?
A．Tired. B．Relaxed. C．Surprised. D．Touched.
3．Why is lure fishing thought as environmentally-friendly?
A．It uses more natural bait. B．It requires fewer resources.
C．It improves the quality of water. D．It maintains fish’s living condition.
4．What does the last paragraph mainly talk about lure fishing?
A．Its expenses. B．Its skills. C．Its benefits. D．Its audiences.
学科网（北京）股份有限公司（23-24高一上·安徽阜阳·期末）Eating too much fat contributes to the risk of stroke (中风) and other heart
diseases. However, it’s the type of fat, not the amount, that appears to be more important when it comes to stroke.
Eating plant-based fats lowers stroke risk, according to a study presentation given at the American Heart Association
Scientific Sessions 2021.
The study, which hasn’t yet been proved by other researchers, found people who ate the most vegetable-based
fats were 12% less likely to experience a stroke compared to those who ate the least. On the other hand, people who
ate the highest levels of animal-based saturated (饱和的) fats were 16% more likely to experience a stroke than those
who ate the least fats of that kind. The findings show the type and different food sources of fat are more important
than the total amount of fat in preventing certain diseases, including stroke.
“You need fa t to survive. Fat helps your body absorb vitamins from foods, build cells, give you energy and
keep you warm. But it’s the unsaturated fats that come from vegetables, nuts and fatty fish that can lower your
cholesterol (胆固醇) level and help keep you healthy. Saturated fats are generally not as healthy, which mainly come
from red and processed meat,” said Dr. Frank Hu, one of the authors of the study.
A proper reduction in red and processed meat consumption with a healthy eating pattern can reduce total
deathrate by 13%, heart disease death by 14%, cancer death by 11% and Type 2 Diabetes risk by 24%, according to
the study.
Interestingly, dairy fat was not associated with a higher risk of stroke, the study found. There has been an
ongoing debate among researchers as to the role of dairy. The diet guide-lines for Americans call for three servings
of low-and no-fat dairy each day.
1．How does Paragraph 2 mainly develop?
A．By making comparisons. B．By analyzing causes and effects.
C．By providing examples. D．By following the order of time.
2．Which kind of food doesn’t have unsaturated fats according to Paragraph 3?
A．Corn. B．Beans. C．Nuts. D．Beef.
3．What is the main idea of the passage?
A．The type of fat matters when it comes to stroke. B．People should eat less red meat to keep healthy.
C．Fat plays an important role in people’s life. D．Americans need three servings of dairy per day.
4．Which section of a newspaper does the text probably come from?
A．Environment. B．Technology. C．Health. D．Travel.
