3 . We have seen lots of science fiction movies about aliens. People travel to stars and even fight with aliens in the movies. But are there real aliens in the universe（宇宙）? Most of us think it is impossible, just like fairy tales. But the answer of some scientists is yes. So they have been searching for aliens in outer space for many years. They hope to find life signs of aliens.

Some scientists are used to using radio telescopes（望远镜）to search for aliens in space. In order to find aliens, they have worked hard for over half a century, but so far they have found nothing. Then some scientists guessed aliens might not want to connect us, but aliens could answer our messages. So some scientists sent radio signals into the universe. They hope one day they would be picked up by alien technology. These scientists want to prove（证明）that we are not alone in the universe.

But what should we do if the “alien phone” rings one day? Should we answer it? Stephen Hawking, the famous physicist, thought it could be dangerous to connect aliens. He said that the main purpose of aliens’ visiting to the earth could be searching for our resources（资源）. But other scientists think we have no need to worry. David Morrison, a NASA scientist, said, “If an alien radio signal reaches the earth from a planet thousands of light-years away, then they almost surely have solved all the problems we still have including the short of resources. Maybe they are much smarter than us, but why do they want to hurt us? I think we can try to connect them.”

Our Milky Way Galaxy may be home to 2 billion planets that have the right conditions to support life. These planets have the correct temperature for liquid water. While no one knows what alien life would look like, if it is anything like life on earth, it would need water to keep alive. According to the research, there are nearly 2 billion habitable planets in the Milky Way Galaxy, which is just one of 100 to 200 billion galaxies in the universe.

The earth was formed 9 billion years after the Big Bang. Many of the planets in the Milky Way were formed millions and some even billions of years before the earth. If intelligent life had existed on any of these planets, they would be much more developed than humans. With that much time to develop the technology for space travel, we should have been visited by aliens many times.

So where is everyone? Some people believe that aliens have visited earth many times, and some governments of the world might have known very well. some believe that we have also been visited many times in the ancient past. They point to the Egyptian pyramids or the huge heads of Easter Island. They say that there was no way that ancient humans were able to create these structures without alien assistance.

According to Harvard professor Avi Loeb,        . For example, in 2017, a cigar-shaped object came within 33 million km of the earth as it passed through our solar system. It was named Oumuamua, which means “messenger from the distant past reaching out to us” in Hawaiian. Loeb says that its unusual shape and the fact that it sped up as it left our solar system sets it apart from anything else we’ve seen. He thinks it was a probe sent by an alien civilization. Jackie Fairey, says everyone should have reservation about this. She is one of many scientists who say there are more reasonable explanations for Oumuamua. That hasn’t stopped Professor Loeb. He has written a new book on Oumuamua called Extraterrestrial: The First Sign of Intelligent Life Beyond Earth.

1. According to the passage, if there were aliens, they ________.

A．could be similar to humans on the earth

B．must help build the Great Wall

C．would be smarter than humans on the earth

D．have a shorter history than humans

2. Which of the following can be put into the blank ________ in the passage?

A．we hasn’t been visited by aliens for we got nothing from the universe

B．we not only have been visited by aliens, but also have evidence

C．no one could be sure about whether the evidence we’ve got is true

D．all of researchers doubt about the fact that we have been visited

3. From the passage, we can infer that ________.

A．there are fewer than 100 billion habitable planets in the universe

B．some aliens did actually, and on the earth in ancient times

C．some governments received information from the oumuamua

D．scientists Leob doesn’t agree with the idea that Fairey holds

4. What’s the best title of the passage?

A．Where are all the aliens?

B．When will the aliens visit us?

C．Oumuamua: Have you ever been here?

D．How many habitable planets are there?

For the first time ever, plants from Earth are growing on the moon. The China National Space Administration (中国国家航天局) showed photos of cotton plants. The administration said the cotton plants were among several plants that were “growing well”. Other plants that are now growing on the moon are vegetables.

The plants are part of a project to the far side of the moon. Project leader Liu Hanlong says the cotton seeds were the first to come up. He said the plants were chosen because they were small, strong and could grow in the difficult conditions on the moon’s surface.

Professor Hanlong said the project’s aim was to understand more about how plants grow outside of Earth. The long-term aim is to develop plants that can grow not only on the moon but also on the Mars (火星).

The professor said: “We have considered the future survival live in space. Learning about these plants growing in a low-gravity (低重力) environment would allow us to know that in the future humans may live in the space.”

1. Plants have never grown on the moon before this project.
2. Chinese scientists showed photos of tea plants growing on the moon.
3. Cotton seeds were the first plants to come up.
4. Scientists said their long-term aim is to grow plants on Venus (金星).
5. There are no chances of survival in space.

______▲______

China’s Zhurong rover (祝融号) has found evidence (证据) showing that water has been on Mars (火星) much longer than expected.

Zhurong, named after the Chinese god of fire, landed safely on Mars on May 15th, 2021, making China only the second behind the United States to fully succeed.

Zhurong, the Mars rover, is 1.85 meters high and weighs about 240 kilograms. It has six wheels and four solar panels (太阳能面板) and it can move at 200 meters an hour on Mars.

The rover’s three-month primary mission (任务) was to search for signs of ancient life. It has done research on the minerals, environment and location of water and ice in the plain. The rover continues to research into its landing place and send information back to the Tianwen-1. The rover returned some information from its primary survey of the basin. It shows that Utopia Planitia basin had water during a time, but many scientists used to believe Mars to be dry and cold.

“Mars is the planet we are most likely to live on in the future. That’s why we want to understand it,” said Ge, a scientist in China’s space program. “Zhurong’s evidence of water on Mars makes great progress in future Mars missions!”

1. China becomes only the ________ to land a rover successfully on Mars according to the passage.

9 . Named after the “quest for heavenly truth”, Tianwen 1, China’s first Mars probe（探测器）, has given us impressive pictures of the red planet. The first high-resolution（高分辨率的）pictures of Mars taken by Tianwen 1 were made public by the China National Space Administration（CNSA） on March 4.

“These are the first close-up pictures of Mars’ surface taken by China, ” said Bao Weimin, a scientist of the Chinese Academy of Sciences.

The pictures were taken at different distances from Mars. The two black-and-white pictures were taken by the high-resolution camera on Tianwen 1 when the probe was about 330-350 kilometers above the Martian surface. As for the color picture, it was taken by Tianwen 1’s medium-resolution（中分辨率的）camera when the probe was about 5, 000 kilometers above the red planet. It shows Mars’ North Pole.

The high-resolution camera can take both color and panchromatic（全色的）pictures. Panchromatic pictures, which are black and white, are the clearest, having the largest amount of data for scientific study, said Liu Tongjie. The medium-resolution camera, can only produce lesser clear pictures. Scientists put the panchromatic and color pictures together to form a clear and beautiful color picture, Liu added.

Tianwen 1, the country’s first independent Mars task, was sent up on July 23, kicking off the nation’s planetary exploration program. The probe entered its preset orbit above Mars on Feb 24 and is looking for a landing site on the planet’s largest plain. The probe is expected to land on the red planet sometime between May and June.

1. When were the first high-resolution photos of Mars made public by CNSA?

A．On Feb 24.

B．On March 4.

C．On July 23.

2. What does the word “It” refer to in paragraph 3?

A．The color picture.

B．The black-and-white picture.

C．The clear and beautiful picture.

3. What do we know about the pictures according to the text?

A．The first close-up pictures of Mars’ surface were taken at different distances from Mars.

B．The color pictures have the largest amount of data for scientific study.

C．The clearest pictures were taken by the medium-resolution camera.

4. What will be most probably discussed next?

A．Tianwen 1 will take more pictures of Mars.

B．Tianwen 1 will land on the red planet, Mars.

C．Tianwen 1 will do some scientific research on Mars.

You might have seen beautiful rainbows in the sky before. They form when sunlight falls on water drops in the air. But in fact, moonlight can also create rainbows in the same way. They are called “moonbows”. They are similar to rainbows, but they are created by moonlight instead of direct sunlight.

Moonbows are rarer than rainbows. Different weather and astronomical （天文学的）conditions have to be just right for moonbows to be created.

The moon has to be very low in the sky-only 42 degrees from the horizon （地平线）. The moon period has to be a full moon or nearly full. The sky must be very dark for a moonbow to be watched clearly-any bright light can obscure it. Water drops must appear in the air in the opposite direction of the moon.

Moonbows appear on the opposite side of the moon and usually look white to the human eye. This is because their colors are not bright enough to be noticed by the human eye. It is possible, however, to view the colors in a moonbow using long exposure （长时间曝光）photography.

Moonbows more often appear in some locations around the world. Most of these locations usually have waterfalls, which create thin fog in the air. Some of these locations are the Yosemite National Park in California and Cumberland Falls State Resort Park in Kentucky, US; Victoria Falls on the border of Zambia and Zimbabwe; and Waimea in Hawaii, US.

Moonbows do really happen. So at a certain time and a certain place, when a moonbow happens to appear, you can’t miss it if you’re right there.

1. According to the first two paragraphs, moonbows are ________.

A．created by sunlight	B．much easier to find
C．seen during the day	D．more difficult to form

2. Which of the following can be the conditions for a moonbow to form?

A．A half moon hangs high in the bright sky.

B．A full moon is 50 degrees from the horizon.

C．A nearly full moon hangs low in the dark sky.

D．Water drops are in the opposite direction of the sun.

3. What does the underlined word “obscure” in paragraph 3 probably mean?

A．cover

B．drop

C．connect

D．produce

4. What is paragraph 5 mainly about?

A．Conditions of moonbows.	B．Background of moonbows.
C．Locations of moonbows.	D．Development of moonbows.
