Mars’s orbit（轨道）around the Sun is the 4th fastest orbit of all the solar system planets. Mars is red in colour and is very cold. Not the coldest of planets in the solar system but very cold all the same. The temperature on Mars is on average 80 degrees, and can get a lot colder at times.

At times in the summer near the Mars the temperature can reach 70 degrees. You may think it’s warm enough to live; however, the atmosphere（大气层）is over 95%. Mars orbits the Sun in 687 days, which means 1 Earth year on Mars is 687 days.

On October 15, 2003, Shenzhou V spaceship was sent into space successfully. Yang Liwei became the first Chinese astronaut to go into space.

To his disappointment, he couldn’t see it. From space, he tried several times to look for the Great Wall, but he failed. In fact, from space, astronauts can’t see any specific（具体的）object on the earth.

He also saw something cotton-like flying outside of the window. He didn’t know what it was. Maybe it was space rubbish.

There was another strange thing. That was the knock on the spaceship. It appeared once in a while. It sounded like someone outside was knocking on the spaceship, but nothing dangerous happened.

3 . 阅读下面短文，在空白处填入适当的内容（1个单词）或括号内单词的正确形式。

Earth — our home and our planet, is a truly amazing place to live. Think about so many kinds of lives living on Earth. If you have ever flown on a plane, you’ve     1     (get) a new respect（尊重） for Earth.

Earth is the only planet known to support life. The     2     (difference) in life forms on Earth are far more than our imagination. On the one hand, there are tiny microbes（微生物）and they can only     3     (see) through a microscope. On the other hand, there are 30-metre long whales that swim through our oceans, covering     4     (thousand) of miles in their ravels.

We have mountains     5     （near）ten kilometres high and valleys（峡谷）many kilometres deep. The     6     (deep) valleys of all are underwater. These undersea valleys can reach 11 kilometres in depth. And yet, even under the pressure of the water at that depth, life still exists. Look at the trees around you. Some trees are over 100 metres tall. That looks     7     a 30-storey building! And they can be 1,000 years old. We have soft grass     8     (walk) on, and trees with needles（针叶）so sharp that they can make your finger bleed if you touch them.

But the most amazing thing about this planet is the people. There are more than seven billion people     9     (live) on this planet. We live in different places and speak different languages,     10     we live on the same planet and enjoy the same sun, the same air and the same water.

Earth — our only home, our great planet. Humans really are so lucky to have such a wonderful place to call home.

7 . 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.

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.

9 . China has named the nation’s first Mars rover（火星车）ZhuRong. For all of us, Zhu Rong is a well-suited name.

In an ancient Chinese story, Zhu Rong had the face of a man and the body of an animal. H rode on two dragons. When he had a big fight with Gong Gong, the god of water, Zhu Rong won. But after the fight, the human world came into complete darkness. Then he brought fire from heaven（天国）to the world.

After leaving the earth last summer, Zhu Rong circled Mars for several months and landed on it in May. In recent years, our country has sent up the world’s first quanturn satellite（量子卫星）, and Chang’e-4 has made a soft landing on the moon. We have made great progress in space technology and will soon start building our own space station.
