The rockets take astronauts and man-made satellites into space. The satellites are used for communication, weather monitoring and research. But how do satellites stay up without falling down?
There are two opposite forces (力量) acting on the satellite. One of them is the force of gravitation (地心引力), which tries to pull the satellite towards the earth. The other force is created by the rotation (旋转) of the satellite around the earth. This force tries to take the satellite away from the earth. With these two forces, the satellite goes round and round. The gravitational pull of the earth (the force which pulls everything towards the ground) is like a rope which keeps the satellite from flying away.
Everything that goes up has to come down. It is only a matter of time before a satellite comes back to the earth. As time goes by, the satellite loses its speed, which makes the gravitational pull stronger than the force pulling it away. This makes the satellite crash (坠落) down to the earth.
【小题1】Which of the following uses of satellites is NOT mentioned?
| A.communication |
| B.monitoring the weather condition |
| C.doing some research |
| D.taking pictures |
| A.the earth |
| B.the satellite itself |
| C.the rotation of the satellite |
| D.the rope |
| A.Because of the force from the earth. |
| B.Because the satellite is too big. |
| C.Because of the force created by the rotation of the satellite around the earth. |
| D.Because people on earth have made ropes to tie the satellites tightly. |
| A.when it flies faster |
| B.when its speed slows down |
| C.when people cut the rope |
| D.when there is no electricity in it |
| A.There are four forces acting on the satellite. |
| B.The force of gravitation makes the satellite go round and round. |
| C.As time goes by, the satellite will finally fall down. |
| D.The satellite will stay in space forever. |
At 9 a.m. on October 15, 2003, our country launched (发射) its first manned (有人的) space-ship, Shenzhou V, into space at Jiuquan Satellite Launch Center in Gansu Province. It took Yang Liwei and his spaceship about 21 hours to circle the earth 14 times. Yang Liwei is China’s first astronaut. He comes from Liaoning Province, and he has been an air force pilot(飞行员) since 1983. He was chosen from 14 pilots after many difficult tests.
The life of an astronaut is hard to imagine for many people. To put on a space suit takes 15 minutes with the help of others. Sleeping in space is not easy, either. He has to sleep in a special sleeping bag on the wall because there is no gravity. Yang can eat chicken and rice. It’s especially made to eat in space but it doesn’t taste nice.
“I’m feeling very good in space, and it looks wonderful here,” said Yang, “I have looked at our beautiful earth and I have recorded all that I have seen here.”
China has become the third country in the world to send a person into space after the former Soviet Union(前苏联) and the United States. China is now planning its next launch. Shenzhou VI will be into space within(在……之内) the next years, it may take three astronauts. We are all proud of our motherland.
【小题1】Shenzhou V was launched into space _____.
| A.at 9 a.m. on October 15, 2003 |
| B.at 9 p.m. on October 15, 2003 |
| C.at 9 a.m. on October 16, 2003 |
| D.at 9 p.m. on October 16, 2003 |
| A.policeman | B.businessman | C.doctor | D.astronaut |
| A.Liaoning | B.Gansu | C.Jining | D.Inner Mongolia |
| A.It took Yang Liwei and his spaceship about 12 hours. |
| B.Life in space is easy for an astronaut. |
| C.China is planning its next launch now. |
| D.Yang Liwei is the first man into space. |
| A.five | B.four | C.three | D.two |
Do you still remember the disaster(灾难)several years ago? In Indonesia (印度尼西亚) thousands of people were killed by the tsunami(海啸) that washed people out to sea and pulled children out of their parents’ arms. “The weather was fine with no clouds .There was no warning and suddenly the sea water just hit the city.
