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.

A blind boy sat there with a hat by his feet. He held up a sign which said, “I am blind, please help.”
There were only a few coins in the hat. A man was walking by. He took out a few coins and dropped them into the hat .He then turned the sign around and wrote something on it. He put the sign back and walked away.
　　Soon the hat began to fill up. A lot more people were giving money to the blind boy. That afternoon the man who had changed the sign came to see how things were. The boy recognized his footsteps and ask, “Are you the one who changed my sign in the morning? What did you do?”
　　The man said, “I only wrote the truth in a different way.”
　　What he had written was, “Today is a beautiful day, but I can’t see it.”
　　Of course both signs told people the boy was blind. But the first sign simply told people to help by putting some money in the hat. The second one told people that they were able to enjoy the beauty of the day, but the boy could not enjoy it because he was blind.
　　The first sign simply said the boy was blind, while the second one told people they were so lucky that they were not blind.
　　There are at least two lessons we can learn from this simple story.
　　Treasure (珍惜) what you have. Someone else has less. Try your best to help those who need your help.
　  Be creative. Think differently. There is always a better way.
