A. There will probably be no school on Mars.
B. It might take us two or three days to get to Mars.
C. There is a problem for us to live on Mars.
D. Food will not be the same.
E. First, people will have more space.
Many people believe that, by the year 2100, we will live on the planet Mars(火星). Here is what life could be like.
First of all, transport should be much better. By 2100, spaceship can travel at half the speed of light. 【小题1】
Secondly, humans need food, water and air to live. Scientists should be able to find plants that can grow on Mars. These plants will provide us with food and air.
【小题2】 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 in many ways. 【小题3】 It is possible to live in a large building with many bedrooms. Then, robot will do most of the work, so we have more time for hobbies.
【小题4】 Every student can study, do their homework on the computer 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. 【小题5】Meals will probably be in the shape of pills(药片) and will not be as delicious as they are today. Also, space travel will make many people feel ill. 查看习题详情和答案>>
If everyone drives such cars in the future, there will be less pollution in the air. There will be more space for all the cars in cities, and there will also be more space for people to walk in the streets.
The little cars of the future will cost less money to buy and to drive. These little cars can go only 65 kilometers an hour, so driving will be safer. The cars of the future will be fine for going around the city, but they will not be useful for a long trip.

| A Solar-powered Plane---Lowcarbon Earlier this month, a solar-powered (太阳能动力的)plane called Lowcarbon took off to the sky for the first time. It has passed an important test on the way to travel around the world. Lowcarbon took off from an airport in Switzerland(瑞士)at 45 km an hour. It slowly rose into the sky. “There has never been an airplane so big, so light, using so little energy,” said Bertrand Piccard, a leader of the project. During the 90-minute flight, Lowcarbon did several turns. It climbs nearly 1.6 km above the countryside. Engineers plan to test a night flight in July. Then they will use the results of the tests to build a second plane. They plan to travel around the world in that plane in 2012. “We want to fly it day and night with no fuel,” Piccard said. Piccard and pilot Andre Borschberg will take Lowcarbon around the world .They will make a few stops to change places and rest after a long time in the air----and to show off their aircraft. Lowcarbon flies at 70 kph on average(平均). That is faster than a bike and slower than a car. The pilots will keep it in the air for up to five days at a time. |
