四、阅读理解
A
Traveling to Mars is usually a lonely business with a single spacecraft taking off to the Red Planet. That
appeared to be the case again on July 30, when NASA’s Perseverance rover (火星车) roared at Cape Canaveral.
But this time the ship will have plenty of company. On July 19, the United Arab Emirates joined the Mars game,
launching Hope spacecraft to orbit Mars. Four days later, China launched its Tianwen-1 spacecraft. And a fourth
mission, a joint Russian-European project, ExoMars, was also planned for this summer.
So why all the interest in Mars — and why right now? The timing issue has everything to do with planetary
mechanics (行星力学). As they fly their differing solar orbits — Earth on the inner track, Mars on the outer — the
distance between the two worlds is forever changing. At their greatest remove, when they are on opposite sides of the
sun, they are up to 250 million miles apart.
But once every two years, they line up on the same side of the sun, with just 35 million miles separating them.This summer just such an alignment (排成直线) is taking place, reducing planetary travel time to seven- month. So
that explains the when question.
The why part is because of Mars’ potentially biological history. The surface of the planet is covered with dry
riverbeds, ancient sea basins, and deep depressions that could only indicate long-vanished water.
Previous rover analyses in similar locations have discovered chemicals that form only in water, proving that
Mars was once extremely wet. Now the mission is to look for fossilized organisms or signs of microbial life.
Perseverance will collect Martian soil samples, awaiting another spacecraft that could leave Earth as early as 2026,
collect the samples and fly them home for analysis.
Finding life on Mars would be a highly significant discovery. The bragging (吹嘘) rights that go with being first
to make the find is part of what makes the planet the hot new destination it’s become.
51．What does the underlined word “the case” in Paragraph 1 refer to?
A．The Mars game. B．Traveling to Mars alone.
C．Having plenty of company. D．A single spacecraft.
52．What can be learned about planetary mechanics?
A．Earth and Mars fly similar solar orbits.
B．Earth travels on the outer track and Mars the inner.
C．Every three years Earth and Mars sit at the same side of the sun.
D．The distance between the two worlds varies constantly.
53．Previous rover analyses indicate that ________.
A．the surface of Mars is full of microbial life B．Perseverance is going to finish its task
C．there may exist life on Mars D．Martian soil samples are easy to get
54．What is the main idea of the passage?
A．Traveling to Mars is becoming hugely easy. B．Finding life on Mars is around the corner.
C．Many nations are going to Mars this summer. D．Living on Mars appeals to people
B
The earth has many mysteries for people to explore and we live on the earth for protection. Do you know that
the earth has two North Poles? There’s the geographic North Pole, which never changes. And there’s the magnetic
(有磁性的) North Pole, which is always on the move. Over the past 150 years, the magnetic North Pole has casually
wandered 685 miles across northern Canada. But right now it’s racing 25 miles a year to the northwest. This could be
a sign that we’re about to experience something humans have never seen before: a magnetic polar flip (翻转). And
when this happens, it could affect much more than just your compass.
Right now on the surface of the planet, it looks like it’s just a bar magnet. Our compasses are just pointing to
试卷第4页，共2页one pole at a time because there’s mainly a two-pole system. But sometimes, the earth doesn’t just have a single
magnetic North and South Pole. Evidence suggests that, for hundreds to thousands of years at a time, our planet has
had four, six, and even eight poles. This is what has happened when the magnetic poles flipped in the past. And when
it happens again, it won’t be good news for humans.
Now you might think, eight poles must be better than two. But the reality is that multiple magnetic fields would
fight each other. This could weaken the earth’s protective magnetic field by up to 90% during a polar flip.
The earth’s magnetic field is what protects us from harmful space radiation which can damage cells and cause
cancer. With a weaker field in place, some scientists think this could expose planes to higher levels of radiation,
making flights less safe.
This could also interrupt the internal sense of direction in many animals that use the magnetic field for
navigation (导航). Even worse, it could make certain places on the planet too dangerous to live in. But what exactly
will take place on the surface is less clear than what will undoubtedly happen in space.
Satellites and space missions will need extra shelter that we’ll have to provide ourselves. Without it, intense
universal and solar radiation will fry circuit boards and increase the risk of cancer in astronauts.
55．Which of the following can best describe the earth’s magnetic field?
A．The focus of scientific research. B．The navigation of satellites.
C．The center of the universe. D．The protective umbrella of humans.
56．What will some animals be faced with when the magnetic poles flip?
A．Losing the ability to hunt for food.
B．Bearing very loud noise day and night.
C．Being unable to find directions exactly.
D．Being unable to protect themselves from danger.
57．What can we learn from the text?
A．Astronauts are more likely to suffer from cancer.
B．The magnetic North Pole is moving faster than before.
C．Flights aren’t allowed to travel as usual when the magnetic poles flip.
D．There are always more than two magnetic poles on the earth at a time.
58．What may be the best title for the text?
A．What will happen when the poles flip? B．The ways that scientists research poles
C．How and when will the poles flip? D．The reasons why scientists research poles
六、用单词的适当形式完成短文
阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。Sitting inside the Shenzhou XVI spacecraft, Gui Haichao, the first Chinese civilian on a spaceflight, together
with the other two astronauts, 59 ( launch) by a 20-story-tall Long March 2F carrier rocket, 60
took off at 9:31 am on May 30, 2023 at the Jiuquan Satellite Launch Center.
Born in 1986, Gui’s 61 (enthusiastic) for science has been developing since childhood. He had a set
of encyclopedias (百科全书) from which he gained a lot of basic space knowledge. Years later, Gui Haichao
attended Beihang University, 62 (major) in spacecraft design and engineering.
Gui then pursued postdoctoral research overseas and published about 20 SCI academic papers in top
international journals. After returning to China, he received Beihang’s invitation to teach 63 an associate
professor.
In the spring of 2018, Gui was told that China’s manned space authorities had made a decision 64
(select) the third group of astronauts, including the first spaceflight engineers and science payloads specialists. “I
have been 65 fan of space exploration for many years and sometimes dreamed about doing my research in
space. So excited was I on hearing this news 66 I signed up without much thought. Eventually I was
67 (successful) admitted following several demanding rounds of 68 (profession) tests,” he recalled.
