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.

| Dear sir, I got married forty years ago. Unfortunately, at that time there was a lot of unemployment and I got no job. I was out of work for about six months before I got another one. Of course I was very short of money. I came to your shop to buy a wedding ring one day. The assistant brought some rings for me to have a look, later she was called away for a moment, and then I put one of the rings into my pocket. When she came back, I said I did not know the size of my girlfriend’s finger. So I left the shop with the ring but I didn’t pay for it. My wife died a month ago, and the fact that I never paid for her ring has been on my conscience(让我良心不安)all these years. I always feel guilty about that. At that time the ring cost $100, and I think that is about ten times at today’s price. Now, I am sending you that amount. Yours truly, A customer |

When the trees die, they provide something good for the earth. New trees can grow strong and healthy in their place.
Some trees even need fires to grow. These trees hold their seeds (种子) inside. Heat from a fire allows the coat of the seeds to open up. Then the seeds fall to the ground and have the _____88____ to grow/
Scientist, who know about nature’s needs, start some of these fires, called controlled burns. A fire is started and kept under control. This way, the fire does not spread out of the area or _____89_____ a after forest fires, they can go hungry _____90_____ their food has been damaged in the fire. Small, controlled fires mean than animals will not have to move far to find food. After some time, small plants begin to grow. Animals return soon after the plants return. This _____91_____ makes an eco-system.
So the next time you hear about a forest fire, think about the good as well as the bad. It may take a new eco-system a while to return, but it will likely come back stronger and healthier than ever.
