任务型阅读  阅读短文,按要求完成各题。(5分)

At the moment, it may be difficult to imagine, but many people believe that, by the year 2100, we will live on the planet Mars. Our own planet, Earth, is becoming more and more crowded and polluted. Luckily, we can start again and build a better world on Mars.

    First of all, transport should be much better. At present, our spaceships are too slow to carry large numbers of people to Mars—it takes months. However, by 2100, spaceship can travel at half the speed of light. It might take us two or three days to get to Mars!

    Secondly, humans need food, water and air to live. Scientists should be able to develop plants that can be grown on Mars. These plants will produce the food and air that we need. However, can these plants produce water for us? There is no answer now.
    There is a problem for us to live on Mars. Mars suck us much less than the Earth does. This will be dangerous because we could easily jump too high and fly slowly away into space. To prevent this, humans on Mars have to wear special shoes to make themselves heavier.

    Life on Mars will be better than that on Earth in many ways. People will have more space. Living in a large building with only 10 bedrooms is highly possible. Many people believe that robots will do most of our work, so we have more time for our hobbies.

    There will probably be no school on Mars. Every student will have a computer at home which is connected to the internet. They can study, do their homework and take exams in online schools. Each student will also have their own online teacher called “e-teacher”.

    However, in some ways, life on Mars may not be better than that on the earth today. Food will not be the same—meals will probably be in the form of pills and will not be as delicious as they are today. Also, space travel will make many people feel ill. The spaceship will travel fast, so the journey to Mars will probably be very uncomfortable.

Two Chinese spacecrafts successfully completed China’s first space docking (对接) early November 3, 2011, which has taken the country a step closer to building its own space station.

Nearly two days after its launch, the unmanned spacecraft Shenzhou VIII docked with the space lab module Tiangong I more than 343 km above the earth surface. Shenzhou VIII and Tiangong I took apart after flying together for 12 days. On the 14th of November, the two spacecrafts finished the second docking. Then Shenzhou VIII parted from Tiangong I again and returned to the earth safely on the 17th. Tiangong I is still traveling around the earth in the space, waiting for the arrival of Shenzhou IX and X and so on in the near future.

That marked another great leap for China’s space program and made China the third country in the world, after the United States and Russia, master the space docking technique (空间对接技术).

The world’s first space docking was achieved in 1966, when the manned U.S, spacecraft Gemini 8 docked with an unmanned Agena Target Vehicle. Space docking is necessary to explore space beyond Earth’s orbit (轨道). “The capability increases China’s ability to act independently in space, as well as its ability to work together with others,” said Gregory Kulacki, a U.S. space scientist and senior analyst.

“With the success of its first space docking, China is now equipped with the basic technology and ability required for the construction of a space station,” said Zhou Jianping, chief designer of China’s manned space program.” The country is on its way to building a permanent manned space station around 2020.”
