Twinkle, Twinkle Little Star is a lovely song for children, but it has two misunderstandings. First, stars aren't little. Some may be Earth-sized, but most are bigger than Jupiter, the largest planet in the solar system. Second, they don't twinkle, they shine. And the brightness and color of the light from each star provide information about its temperature, size and even its age.
Viewing the stars from Earth is a bit like looking at them through a water filter because the air is thick compared to the emptiness of space. What's more, air is always moving, so starlight appears to be moving, too. The air also makes stars appear dimmer than they are if we could see them from space.
If you stop and view the sky on a dark and moonless night, it's easy to find color differences among stars. The color of a star is a signal of its surface temperature. The hottest stars are blue, and the next hottest are white. Yellow stars like the sun are next, while red stars are the coolest of the visible stars. Many red stars are so dim that people can't see them at all, and some stars hardly send out any light at all. One reason that stars differ in brightness is that hotter stars produce more energy than cooler ones, but another important reason is that some are much bigger than others.
Some stars appear brighter to human beings simply because they're closer. Astronomers rank the brightness of stars which are seen from Earth by giving them a name known as magnitude (星星的亮度)- the smaller the magnitude, the brighter the object. They have also designed a number that ranks stars according to how bright they are when compared to each other. With a magnitude of minus 26. 7, the sun is the brightest object in the sky.
39. From the song quite familiar to children, the writer wants to prove that __.
A. most stars are smaller than Jupiter
B. Jupiter is smaller and brighter than Earth
C. stars are very large and always shine brightly
D. starlight's brightness and color are the signs of its temperature
40. The underlined word “them” in Paragraph 3 refers to many ____ stars.
A. white　 B. blue
C. yellow　 D. red
41. From Paragraph 3, we can know that ____.
A. a red star often sends out much brighter light
B. a blue or white star is hotter than a red or yellow star
C. a yellow star like the sun is the hottest in space
D. a blue star is much bigger than stars in other colors
42. Which is the best title of this passage
A. What do stars look like
B. Which song do children like best
C. How to view the stars from Earth
D. Why are many stars so dim at night
C
Have you ever heard of satellites(卫星) What are they used for
Satellites are helping to forecast(预报)the weather now. They are in space, and they can reach any part of the world. The satellites take pictures of the atmosphere, where the weather forms. They send these pictures to the weather stations. So meteorologists(气象学家)can see the weather of any part of the world. From the pictures, the scientists can often say how the weather will change so that it can work better for people.
Nowadays, more and more countries have weather satellites. Nearly five hundred weather stations in sixty countries receive satellite pictures. When they receive the new pictures, the meteorologists compare them with the earlier ones. Perhaps they may find the clouds have changed during the last few hours. This may mean that the weather on the ground may soon change, too. In their next weather forecast, the meteorologists can say the weather will change soon. So the weather satellites are a great help to the meteorologists. Before satellites were invented, the meteorologists could only forecast the weather for about 24 or 48 hours. Now they can make good forecasts for about two weeks. Soon they may be able to forecast the weather for more than two weeks or more ahead.
With the development of the society, weather satellites will work better and better in people's life.
43. From the second paragraph we can know satellites travel ____.
A. in the atmosphere　 　 B. in space
C. on the ground　 　 D. in the clouds
44. Nowadays, meteorologists forecast the weather ____.
A. without studying satellite pictures
B. before receiving satellite pictures
C. when receiving satellite pictures
D. after comparing the new satellite pictures with the earlier ones
45. According to the passage, maybe meteorologists will soon be able to forecast the weather for ____.
A. about 24 or 48 hours
B. about a week
C. less than two weeks
D. more than 14 days or even longer
46. What's the main idea of this passage
A. Satellites can reach any part of the world.
B. Satellites can take pictures of the earth.
C. Satellites are used for forecasting the weather.
D. More and more countries have weather satellites.
D
Chang'e 5 Back Home
In an ancient Chinese story, a lady named Chang'e flew to the moon alone. She never came back home.
However, another Chinese “Chang'e” just came back. After weeks of space travel, the Chang'e 5 lunar probe (月球探测器) came home on December 17, 2020. It landed in Siziwang Banner in the Inner Mongolia Autonomous Region.
Chang'e 5 brought back China's first samples (样本) of rock and soil from the moon. They were the first lunar samples in over 40 years since the Soviet Luna 24 probe in 1976, China Daily reported. China has become the third country in the world to successfully bring back rocks from the moon.
The return of Chang'e 5 was the last step in China's three-step lunar exploration program(探月工程). It began in 2004, including orbiting(环绕飞行), landing, and bringing back samples, Xinhua reported.
47. When did the Chang'e 5 lunar probe come back
A. On December 17, 2020.
B. In 1976.

If you watch the sky for about an hour after the sun goes down, you may see some “moving stars”. But they're not real stars. They're man made satellites(人造卫星). And the biggest of all is the International Space Station (ISS). From May to July is the best season to watch the ISS flying over the earth. And people can see it with their eyes.
The ISS is the biggest man made satellite and scientists can live on it. They think that the best way to learn more about space is to live there.
The space station is like a city in space. People can stay and study there with many of the things they have at home. Laboratories, living rooms and power stations are built. The ISS is the most expensive space program. Billions of dollars are spent on it every year.
Scientists hope that the ISS will be a stepping stone for future space exploration(探测). “The ISS will help us understand the human body better, explore space and study the earth. It can help us make life on the earth better,” said Kathryn Clark, an ISS scientist.
Sixteen countries are part of the program: the US, Russia, Canada, Japan, Brazil and 11 European countries. China isn't an ISS country, but it has helped with some of the experiments.
50. The International Space Station ____.
A. is really a big city in space
B. is the biggest man made satellite
C. can only help us explore space
D. is mainly built by the USA and Russia
51. The underlined phrase “a stepping stone” probably means “____”.
A. 滑梯 B. 巅峰 C. 垫脚石 D. 走廊
52. Which of the following isn't mentioned
A. China will become the ISS country in the future.
B. Living rooms are built on the ISS.
C. The ISS will be more useful in the future.
D. The ISS costs the members of 16 countries plenty of money every year.

Space travel sounds exciting, doesn't it Now if you have enough money, you can go to space to see our earth. You can stay in space for a few days and eat some special food which is for astronauts.
In the future, space travel may be more exciting. People can travel in space and get to other stars. Today, if you want to go to Mars (火星), how long do you think it will take That will be a long trip. Even in the best spaceship(宇宙飞船), it will take about one year. In the future that will not be a problem. Spaceships can travel very fast. Perhaps we won't use the spaceships at all. We may use the wormhole(虫洞). It's like a gate. Once we pass through the gate, we will arrive at another place far away from the earth. It may take a few minutes. Science develops very fast. We believe that one day in the future, the dream of traveling from one star to another will come true.

六、 Life on Mars
In the future, we can travel to Mars by space shuttle which travels at half the speed of light. We can live on Mars because scientists develop plants that can grow on Mars and can produce food, oxygen and water. The gravity on Mars is only three eighths of the gravity on the Earth, so we should wear special boots to make ourselves heavier.
On Mars, we will have more space and more free time, so we can live in a home with many rooms and have more time for hobbies. Students on Mars can study at home on the interplanetary computer network.
But the food on Mars will not be as tasty as that on the Earth, and the journey to Mars will probably be very uncomfortable.
