From a plane you can see the fields, cities, mountains or rivers below. If we go into space, we see more and more of the earth. People and man—made satellites (卫星) are sent into space to look at the earth, the stars and other planets and learn more about them.

The moon is our nearest neighbor in space. It is our satellite and men have visited it already. It is smaller than the earth. Plants can’t grow on the moon because there is no air or water on it. There are lots of mountains on the moon. At night, it is very cold on the moon. It is not comfortable to live on the moon if possible. On the moon, there is much dust here and there. The things on the moon are much lighter than the things on the earth.

The moon hasn’t its own light. It shines back (反射) the light of the sun. When the sun is shining on the side of the moon that faces us, it looks like a great round ball. We can’t see the moon when the sun is shining on the side of the moon that faces away from us.

In fact, the moon isn’t as near as it looks. It is 380, 000 kilometers away from the earth. Of course we can fly to the moon in a spaceship. It only takes more than three days to get there by spaceship.

【推荐1】①Most people have a place to call home on Earth. What about in outer space? The International Space Station(ISS) became our first “home” in space in 2000. It welcomed its first crew(队) that year, paving the way(铺平道路) for 20 years of future research.

②“You just have this impression that we’re all citizens(公民) of not a country, but of the planet,” former NASA astronaut Scott Kelly told National Geographic about working in ISS. “We’re all in this thing called humanity(人类) together.”

③Over the past 20 years, the ISS has mainly been used as a science lab, hosting 241 people from 19 countries, according to NASA. They have gone on spacewalks, done research on how space affects the human body, and even grown plants in space.

▲ . For example, the station’s water purification(净化) technology has been used in poor areas to provide clean drinking water. The station also helps to warn us of natural disasters(灾难), such as earthquakes.

⑤However, after being our home in space for over 7,000 days, the station is starting to get old. It has leaked(泄漏) air a few times. Scientists think that the station can keep working until 2024. After that, scientists will bring it down to Earth. It is believed that Earth’s atmosphere(大气) will burn up most of the station. Other debris(残骸) will fall into the Pacific Ocean.

⑥In the future, space will be home to more stations like the ISS. NASA is building a space station that is smaller than the ISS near the moon. Also, China will have its own space station up in 2022.

1. What did Scott Kelly feel about his work in space?
A.ComfortableB.ProudC.BoredD.Lonely
2. The astronauts have _______ while working in ISS.

(a. gone on spacewalks        b. provide clean water for poor areas       c. stopped earthquakes       

d. learned how space affects the human body            e. grown plants )

A.abcB.abdC.adeD.bde
3. Which of the following sentences can be put in the .
A.We don’t know why we call the ISS our first “home”.
B.The station has also done something good to us on earth.
C.You want to know who has visited the ISS over the years.
D.People may wonder how scientists live on the station.
4. If we put the passage into three parts, which of the following is the best?
(Para. 1=① Para. 2= ② Para. 3=④ Para. 4=④ Para. 5=⑤ Para. 6=⑥)
A.①;②③④⑤;⑥B.①;②③④;⑤⑥
C.①②;③④;⑤⑥D.①②;③④⑤;⑥

【推荐2】Astronauts go on spacewalks for many reasons. Spacewalks let astronauts work outside their spaceship while still in space. Astronauts can do science experiments on a spacewalk. Experiments can be placed on the outside of a spaceship. This lets scientists learn how being in space influences different things. Spacewalks also let astronauts repair satellites or spaceship that are in space. By going on spacewalks, astronauts can fix things instead of bringing them back to Earth to fix.


When astronauts go on spacewalks, they wear spacesuits to keep themselves safe. Inside spacesuits, astronauts have the oxygen(氧气)they need to breathe. They have the water they need to drink.

Astronauts put on their spacesuits several hours before a spacewalk. They leave the spaceship through a special door called an airlock. The airlock has two doors. When astronauts get ready to go on a spacewalk, they go through the first door and lock it tight behind them. They can then open the second door without any air getting out of the spaceship. After the spacewalk, astronauts go back inside through the airlock.

When on a spacewalk, astronauts use safety tethers to stay close to their spaceship. One end is tied to the spacewalker. The other end is connected to the spaceship. The safety tethers keep astronauts from flying away into space.

1. What is one kind of important work that astronauts do during spacewalks?
A.Watching the earth from the space.B.Wearing spacesuits to keep warm.
C.Making repairs to objects.D.Doing tests on their bodies.
2. Which is the correct order for Astronauts to prepare for spacewalks?
①lock the first door tight                    ②put on their spacesuits
③go through the first door                       ④open the second door
A.②④③①B.①②③④C.②③①④D.③①②④
3. The underlined word "tethers" in the last paragraph means__________ in Chinese.
A.绳;链B.工具C.措施D.头盔
4. What is the main idea of the passage?
A.Astronauts wear spacesuits to breathe and move in space.
B.Astronauts need special machines to study other space.
C.Astronauts do important experiments in space.
D.Astronauts have special tools to stay safe and work in space.

【推荐3】Do stars only appear at night? The answer is no. Venus (金星) is the only star that can be seen in daytime. It shone at its brightest in the night sky on Feb 17 this year.

Venus is the second planet from the sun. It is the second brightest natural object, behind the earth’s moon, in the night sky. Why is it so bright?

First of all, Venus is the closest planet to the earth. It is also covered by highly reflective (反射的) clouds, which can reflect about 70 percent of the sunlight striking (照射) it, almost twice as much as the earth does. Some people call 2017 the year of Venus, because the planet is at its brightest twice this year. Venus gets brighter when it goes further away from the sun, and nearer to the earth. The brightest moment happened once in February, and will happen again, during daylight, on April 30.

If Venus is so bright and close to us, isn’t it a better choice for human exploration (探索) than Mars? It is closer to the earth than Mars and it’s closer to the earth in size. The closer distance to the sun means solar power (太阳能) would be easier to generate as well.

However, with a temperature of about 465℃ on the surface, Venus is the hottest planet in our solar system!

But scientists never give up. Recently, a team of NASA and Russian scientists created new computer equipment that can stand temperatures of 480℃. It can work under Venus-like conditions (环境) for almost 22 days.

The next step, according to the scientists, is to send a probe (探测器) to Venus by 2025.

1. Which of the following about Venus is NOT true?
A.It’s the only star that can be seen in daylight.B.It’s the second planet from the sun.
C.It’s the brightest natural object in the night sky.D.It’s the closest planet to the earth.
2. The underlined word “generate” is similar in meaning to the word “________”.
A.heatB.produceC.spreadD.form
3. What makes Venus a worse place for human exploration than Mars?
A.The closer distance to the earth.B.The similar size to the earth.
C.Too much solar power to use.D.The extremely high temperature.
4. According to the last two paragraphs, the new computer equipment ________.
a. was created by some UK scientists     b. can stand temperatures of 480℃
c. can work for about 22 days on Venus     d. will be sent to Venus by 2025
A.abB.bcC.cdD.ad
