________ does a space plane shuttle? It looks like an ordinary plane.

[　　]

Scientists are very interested in the Universe，and they always want to know more about it. Years ago they knew many things about the moon. They knew how big it is and how far away it is from the earth. But they wanted to know more about it. They thought the best way was to send men to the moon. The moon is about 384,000 kilometers away from the earth. A plane cannot fly to the moon because the air reaches only 240 kilometers away from the earth. But something can fly even when there is no air. That is a rocket(火箭)
How does a rocket fly? There is gas（气体） in the rocket. When the gas is made very hot inside the rocket, it will rush out of the end of the rocket, so it can make the rocket fly up into the sky. Rockets can fly out into space. Rockets with men in them have been to the moon. Several rockets without men in them have flown to another planet(行星) much farther away than the moon. One day, rockets may be able to go to any place in space.

Maybe you know floods, droughts, earthquakes, sandstorms and so on. But have you ever heard of typhoons?

Typhoons are some of the worst storms, usually around the Pacific Ocean and the South China Sea. Most happen in July, August and September.

How does a typhoon happen? When lots of sea water gets hot in the summer sun, it evaporates into the air. This makes the air hotter. When the air gets warm enough, it starts to move higher up into the sky. Then, cooler air around it rushes in. It fills the space that is left. After the air gets warmer, it starts to move quickly, making wind. The wind goes in circles, and it keeps moving higher in the sky. The warmer the air gets, the quicker the wind moves. And when the wind moves faster than 30 meters a second, a typhoon begins.

A typhoon has two parts. One is called the "eye". In the eye, the wind does not move so fast. The other part is the wall of clouds around the eye. This is where the strongest wind and hardest rains are.

Typhoons are very dangerous. In 2004, Typhoon Yunna killed 164 people in Zhejiang, and 24 people were missing. In May 2006, Typhoon Pearl hit Guangdong and Fujian, and thousands of houses were damaged.

What to do when a typhoon hits:

·Stay inside, close all the windows and stay away from them.

·Try to bring all of your things inside. Strong winds could even blow away your bikes!

·Listen to the radio or TV for important information.

·If you're told to go to a safer place, do so right away.

1.Which picture can tell meaning of the underlined sentences "... it starts to move higher up into the sky. Then, cooler air around it rushes in. '?

2.When a typhoon comes, we cannot

A．close all the windows

B．listen to typhoon news

C．stay outside with our bikes

D．stay inside the strong house

3.Which of the following is TRUE according to the passage?

A．The warmer the air gets, the slower the wind moves.

B．This year Typhoon Peal killed 164 people in Zhejiang.

C．The strongest winds and hardest rains are in the eye of typhoon.

D．A typhoon will happen when the wind goes faster than 30 meters a second.

Have you ever seen people building houses? To build a house , you need workers. They use their hands , tools(工具) and machines to put things together. Building the ISS（国际太空站） is the same. The difference is that the workers are astronauts. They walk in space and use robots’ arms and hands to do their work.

In the space station ,astronauts are comfortable. The temperature there is about 21℃.But outside the station , it can be too hot or cold for people. In the sunlight, it’s about 120℃. In the shadow(阴暗处)of the station, it’s about -85℃ . So when astronauts walk in space , they have to wear heavy clothes----spacesuits.

Spacesuits also keep astronauts safe from flying rubbish(垃圾)in space.Each time people go into space , they leave rubbish there. So astronauts should be careful because there’s a lot of rubbish, some rubbish goes many times as fast as a plane !

Space walking is not easy , and it can be dangerous. So getting ready for it takes a lot of time to learn. Astronauts will need to do 160 space walks to finish their work in the ISS. That will take about 1,900man-hour of work.

1.What’s the temperature in the space station?

A. 21℃ B120℃ C. -85℃ D.-21℃

2.The astronauts work in space with

A.scientists’ hands B.tools in their hands

C.robots’ arms and hands D.workers’ hands

3.Which of following is TRUE according to the passage?

A.Space walking is very comfortable

B.Space walking is difficult

C. Astronauts needn’t wear spacesuits when walking in space.

D. Space walking is very safe

4.What does the underlined word“spacesuit”mean in Chinese?

A.太空服 B.防暴服 C.羽绒服 D.雨衣

5.Which of following is not TRUE according to the passage?

A.Spacesuits can keep astronauts warm

B. Spacesuits can keep astronauts safe

C.Flying rubbish in space goes very slowly

D.Outside the station ,it can be too cold or hot for people.

________ does a space plane shuttle? It looks like an ordinary plane.
