Have you ever been to Wuyuan? It is in the northeast of Jiangxi Province. People call it “the hometown of
books”, “the hometown of tea” and “the most beautiful village in China”.
I went there with my friends in April this year and had a wonderful experience. At first, we saw many ancient
buildings surrounded by green trees and clear brooks (溪流). It was said that they were built during the Tang
Dynasty. Then we visited Changxi village, a place famous for producing high mountain green tea. People lead a
quiet and simple life there. They shared the tea culture with us and told us how to enjoy the fresh tea. Next we
passed through the oldest lane (空中走廊) to experience the beautiful Rainbow Bridge. Although it was built 800
years ago, it stands as sturdy (坚固的) as ever. So it is still in use by the villagers now. I really liked this bridge
because it could protect people from getting wet on rainy days. After that, we had a look at the Yuanyang Lake. It is
in the west of Wuyuan and got the name of “Provincial Nature Reserve” in 1997. Along the lake is a forest with
about 185 kinds of plants that are green all year round.

As everybody knows, tourism (旅游业) plays an important part in the development of a country, the life of
people and so on. It can open our eyes to the outside world, bring us more knowledge, and make us feel good.
However, tourism can also lead to pollution and many other problems to places of interest (名胜古迹).
Luckily, “Green Tourism” is now being promoted and developed around the world. As time goes by, people
will begin to realize the importance of these places of interest. “Green Tourism” teaches a person to love nature
more and to protect it by enjoying its beautiful scenery (风景) and learning more about it. “Green Tourism” is the
best kind of tourism as its purpose (目的) is to let people enjoy natural environments including wild plants and
animals, and of course the cultures of many places.
Compared with traditional tourism, “Green Tourism” is to learn more about nature and people. Traditionally,
people travel around the world to enjoy themselves and pass time pleasantly. But “Green Tourism” are different.
The tourists travel because they fall in love with the beauty of the protected areas. They want to make good use of
natural resources (资源) but not use them up. For example, they study the animals, the culture and the customs (风
俗) or a place so that they can learn more about the history and value (价值) of the area.
In short, “Green Tourism” has a purpose and a plan, but not to pollute our places of interest.

People read books less often these days. With the invention of TVs , computer games and mobile phones, it
seems that reading books is no longer a popular activity. However, I believe that books are an important part of our
lives.
Books offer an outstanding wealth (财富) of learning and are at a cheaper price than taking a course. Books
can make people cleverer, because heavy readers have greater knowledge(知识) of how things work and who or
what people are.
Everything needs reading. Imagine trying to do something as simple as reading the notes(注意) on a medicine
bottle(瓶子) without good reading skills. Someone could not understand them and become very sick or even die.
Even something as simple as walking or driving through the city could become very dangerous without
enough reading. Sometimes, you must be able to understand what is written and explain the meaning of them.
With a book, you can travel anywhere you want, do anything you want, and talk to anyone you want. Reading
is very important in our lives, no matter your age.
So I think people should read books.
11．________ is the least often of the following activities these days.

Education
English Teacher Uses Creative Cartoons in TeachingA high school English teacher who has an artistic talent is encouraging (鼓励) her students with colorful
drawings in her pupils’ exercise books.
Du Mengsi, who teaches at a high school in Xuchang. Central China’s Henan Province, said some of her
students lacked (缺乏) interest in learning English. So she started to draw cartoon characters for her students who

A box of strawberries is left to rot (腐烂) in your fridge. You must throw it away at once. But it’s more than
just strawberries that you are wasting.
The life of a strawberry starts from a seed (种子). A farmer plants the seed and waters it. Later, people pick the
strawberry and pack it in a box. A truck takes it far—perhaps 200 to 1,000 kilometers—to a supermarket. Water,
labor, fuel (燃料) and money must all be spent in order for a strawberry to come to you. If you waste the
strawberry, you will waste all of these things.
It’s hard for people to realize how much work is connected with the food we eat every day. That makes food
waste a big problem around the world. Every year, the total amount of food wasted around the world is 1, 3 billion
tons. In China alone, people waste 35 million tons of food each year, according to the CCTV.
As we throw food away, there are still 820 million people living in hunger (饥饿) around the world. Many
children go to sleep hungry, and 3.1 million of them die from hunger each year, according to the UN. The Covid-19
pandemic (流行病), has made the situation worse, with many countries no longer transporting (运输) food to other
countries during this time.
Wasting food means wasting natural resource and missing the chance to feed a growing population. It’ s time
to take action (采取行动) now. Many countries are fighting food waste. What are we Chinese doing to stop it?
China has taken an activity called “Clear Your Plate” since 2013. This year, some restaurants are encouraging
people to order food using “N-1”. “N” stands for number of diners at a table. If there are 6 people at your table,
your are encouraged to only order 5 dishes.
With people living better lives these days, they are forgetting old values. It’s time to bring them back. We
should clear our plates from now on.
21．The underlined sentence “But it’s more than just strawberries that you are wasting.” means that ________.
A．there are more strawberries in your fridge B．you are wasting not only strawberriesC．more strawberries will rot in your fridge D．you will waste more strawberries then
22．What makes food waste a big problem?
A．A lot of food goes bad easily.
B．It’s hard to bring food to people.

I was lying in bed yesterday afternoon after a big lunch. There wasn’t anything interesting on television. The
book I was trying to read seemed boring, too. Finally I put the book down, closed my eyes.
Suddenly, I felt a little and wet tongue lick my face. My eyes opened and I saw our dog Luck standing there
and looking at me. I smiled and touched her head. After a while, I got up and we went outside. The sun was
breaking through the clouds and warmed the cool air. I laughed as I ran with her around the yard.
She smelled the grass when the wind blew lightly. After we went back inside, I threw a ball to her, and she
brought it back to me happily. Then she jumped up on my bed and took a nap of her own. It seemed like even while
she was resting, she never found life boring.
Luck’s life is always full of happiness. In her life, there is time to nap and time to play. There is time to sing, to
listen to the news, but there is no time to be bored. After thinking about Luck’s life, I know we only get a certain
amount of time to live and that we shouldn’t waste a second of it.

March 5 is Lei Feng Day. People are encouraged to help others and to learn from Lei Feng. This year, my
classmates and I went to do some cleaning in a street. We finished our work, took photos and talked with some
people about their lives. One old lady said she remembered how all students used to do helpful work in the street.
Another told us that when she was young, she and her friends would do a lot of simple things to help others. They
would help people carry things or fix broken chairs at school. “But things have changed over these years. The
young students don’t really understand the spirit of Lei Feng,” she continued. “They do good things because they
are told to do and take photos to put on the school website (网站).”
Her words made me think. We have been told to do things to help others on Lei Feng Day. But none of the
love and care came from our own hearts. We should believe that they can make a difference. We don’t need
cameras or praise (赞美). We can do better if we keep the spirit of Lei Feng inside ourselves. “Learn from Lei
Feng” shouldn’t be a yearly fad. Everyone should carry out their good behaviors all year round and we will have a
better tomorrow.

Over your lifetime, your parents are likely to influence you more than anyone else. So if your dad likes
football, you might grow up being a football fan. And if your mum loves reading, you might grow up carrying a
book, wherever you go, just like she does. It’s interesting, isn’t it?
But have you ever thought of how to get along with them? You should spend more time with them. It might be
easy to stay in the same place with your mum or dad. But how much time do you spend just enjoying each other’s
company（陪伴）? Instead of playing a computer game or watching TV, you can ask your mum and dad to play
outside with you.
You should also share your feelings with them. Many kids say they’d like their parents to help them when
they’re in trouble. But your mum or dad might not know that you’re having some trouble. So please tell them if
you’re sad.

Do you use a phone while walking on the road? Today, more and more people spend too much time watching
the phones. We call these people the“Heads-down Tribe (低头族)” and we can see them everywhere.
More traffic accidents are happening because more drivers use phones when driving. So we’ve made some
traffic rules to make drivers drive more carefully. For example, heads-down tribe members who use phones when
driving in Taiwan will be fined.
Keeping heads down and using phones may cause accidents. Also, some interesting and strange facts happen
to the “Heads-down Tribe”. Let’s have a look at the TV report. A man in America kept using his phone on his way
home. As a result, he walked into a big lost bear. When he looked up, he was so scared that he turned around and
ran away. Another fact is that we often see people in the restaurant eating face to face but focusing on (专注于) the
phones. Some of them even have fun communicating with others on the phone.
Phones are helpful tools for modern people. Are they good or not? It depends on how people use them. Let’ s
be “healthy” users and try to be the“Heads-up Tribe”.

Joyce was born in a poor family. Next Friday would be her mother’s birthday. Joyce wanted to buy something
for her mother, but she had no money. As an 8-year-old girl, she couldn’t do part-time jobs. What could she do to
make enough money for her mother’s birthday present?
Suddenly she had an idea. Usually, she would go straight to school, but this morning, she didn’t. She walked

Eight days later, she decided to sell all the things she had collected（收集）because the next day was her
mother’s birthday. She had to sell them and buy a birthday present for her mother. In the shop, she bought a

“Green mountains and clear waters are as good as mountains of gold and silver”. To make our water clearer
and our mountains greener, we should start doing garbage classification(垃圾分类).
There are four kinds of wastes: the hazardous（有害的）, the recyclable（可回收的）, the dry and the wet.
The used books and notebooks should be put into the recyclable garbage bins, the batteries should be put into the
hazardous garbage bins, the dry leaves should be put into the dry garbage bins and the leftovers（剩饭菜）should
be put into the wet garbage bins.
The other day, I found a lady in my neighborhood. She put all the garbage into one garbage bin. She was not
doing the garbage classification. When I went to tell her to do it, she looked confused（迷惑的）. I realized she
knew little about garbage classification. It’s not hard to imagine things like this happen a lot every day.
There is a question coming to my mind—Are we doing enough to let people realize the right way to classify
the garbage? It seems many people need education on that. We can start to help children know the right thing to do
with garbage. As students, we can set up a volunteer team in the garbage station to help those uncles and aunts to
put the garbage in the right bin. We can also let them know the benefits of doing this.
If we keep on doing this, our environment will get better. We can see more green mountains and clear waters
around us in the near future.
61．How many kinds of wastes are mentioned in the passage?
A．4. B．5. C．6.
62．Where should we put the leftovers?

B．Students don’t know much about garbage classification.
C．There is still a lot to do about garbage classification.
65．What can we learn from the passage?
A．Garbage classification helps us see more green mountains and clear waters.
B．Garbage classification can make mountains of gold and silver.
C．Garbage classification is too hard to do it in our daily life.

Gift giving is an important practice that can show a number of different meanings. Here are some gift giving
traditions from a few different countries.
◆In Zimbabwe
In Zimbabwe, it is common to ask for a gift straightly. When a gift has been bought even without asking for it,
the worst thing you can do is to refuse the offering, even if the giving family is poor.
◆In Japan
The Japanese place a great importance on the act of gift giving. For example, people don’t like uncovered
money. So whether you’re sending money as a gift or just leaving a tip (小费), put your money in an envelope (信
封).
◆In India
As left hands are considered unclean in Indian culture, acts such as touching, passing money, or giving gifts
must be done with your right hand.
◆In Russia
Vodka (伏特加酒) might seem a perfect gift for a Russian, but in fact, a lot of them would see it as an
unimaginative gift. Many even think the idea is terrible.
◆In Ireland
Don’t be astonished if your gift is refused a couple of times in Ireland. This tradition comes from a time when
they didn’t have enough potatoes to eat in the 1840s, and because of this, the receivers are making sure that you can
really part from the thing that you are offering.
66．From the passage, we can know that ________.
A．it’s common to refuse gifts in Zimbabwe
B．Japanese people don’t send money as a giftC．Indian people use right hands when giving gifts

The warming of Earth’s climate (气候) is called global (全球的)warming. If global warming carries on, many
plants and animals living today on the Earth could have problems surviving (生存). It could also mean more
droughts (干旱) and floods (洪水). Over the last one hundred years, the average (平均的) temperature on the Earth
has gone up by half a degree. It doesn’t sound much, but people are very worried. Global warming is caused by the
greenhouse effect (温室效应). What is it? It’s what keeps our planet at a nice and comfortable temperature and the
best way to explain how it works is to look at a greenhouse.
Why is it hot inside a greenhouse? Have you ever noticed that it’s warmer inside a greenhouse than outside?
This is because rays (光线) of sunlight pass through the glass of the greenhouse. Although the greenhouse’s glass
lets sunlight in, it doesn’t let all the heat out, so some of the heat is trapped (困住) inside the greenhouse and it
warms up. The atmosphere (大气) is a bit like the glass of a greenhouse. It lets sunlight pass through easily but
stops some of the heat getting out. So when the rays of sunlight heat the Earth, it warms up. The Earth gives out
heat, but not all of it gets into outer space. Some of it gets trapped close to the Earth and this warms up the air
around us. Without the greenhouse gases (气体), the Earth would be about 33℃ coder. It would not be warm
enough for plants and animals to survive. The way that greenhouse gases keep the atmosphere at a nice temperature
is called the greenhouse effect.
