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.
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.
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. 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.
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. 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.

Almost everyone has dropped some food on the floor and still wanted to eat it. If someone saw you drop it, he or she might have shouted, “ 5-second rule!” This so–called rule says food is OK to eat if you pick it up in five seconds or less. But is that true?
Professor Anthony Hilton from Ashton University, UK, tested the rule with his students. They found that food dropped for five seconds is less likely to contain bacteria(细菌) than if it sits there for longer.
For the study, Hilton and his students tested a lot of foods——bread, pasta, cookies and candy—to see how much bacteria they had when they made contact with the floor. They allowed the food to lie on the different types of flooring—carpet(地毯), laminate (复合地板) and tile(瓷砖) — for three seconds to 30 seconds.
Not surprisingly, the longer the food was on the floor, the more bacteria it had. And the type of floor where the dropped food landed had an effect. Bacteria are least likely to transfer(转移) from carpet, while they are most likely to transfer laminate or tiled surface after more than five seconds.
The study also found that the wetter the food, the more likely it was to pick up bacteria. Although most people are happy to follow the 5-second rule, eating food dropped on the floor still carries an infection(感染) risk. “It very much depends on which bacteria are on the floor at the time.” Hilton told Forbes.
What is the “5-second rule’ mean?
| A．People often shout at someone when they drop food on the floor. |
| B．Food is safe when you pick it up off the floor in less than five seconds. |
| C．It’s better to eat dropped food when it’s been on the floor for over five seconds. |
| D．Food will go bad when dropped food on the floor in five seconds or less. |
Where is Ashton University?
A. In the USA. B. In England.
C. In China. D. In France.
Hilton’s test wanted to find out____________.
| A．if the “5-second rule” is true |
| B．the students’ favorite food |

According to the test, we learn the following EXCEPT ________.
| A．the dropped food had more bacteria if it sat on the floor for longer. |
| B．the dropped food on the carpet had the least bacteria. |
| C．bacteria was impossible to transfer from laminate or tiled surfaces. |
| D．the wetter food was likely to pick up bacteria. |
According to the article, the infection risk of the dropped does NOT depend on _____________.
| A．how long the food sits on the floor |
| B．what the dropped food is |
| C．what the bacteria are |
| D．what the weather is like that day |
One day a man found a cocoon(蚕) of a butterfly in the forest. He sat there for several hours and watched the butterfly. Suddenly, a small opening appeared and the butterfly made its great effort(努力) to force its body through that little hole. Then it seemed to stop making any progress. It appeared as if it had gotten as far as it could and it could go no further.（那个蛹好象忘记了它该怎样做, 也好象停止了挣扎）.
So the man decided to help the butterfly. He cut off the remaining bit of the cocoon so that the butterfly would come out easily. But to his surprise, the butterfly got a heavy body and very small wings when it came out of the cocoon.
The man continued to watch the butterfly because he expected that the body would grow smaller at any moment and the wings would become larger and be able to fly. But neither happened! In fact, the butterfly spent the rest of its life crawling(爬) around with a heavy body and small wings. It was never able to fly.
The man was in his kindness, but he didn’t understand the nature rules. Before the butterfly came out of the cocoon, fluid(液体) from its body must be forced into its wings, and then would be ready for flying. It must have a hard struggle(拼搏) to get through the small opening to get its freedom from the cocoon.
Sometimes struggles are exactly what we need in our life. If God allowed us to go through our life without any difficulties, it would make us fail. We would not be as strong as we could have been, we could never fly.What was the butterfly doing at the beginning of the story?
| A．It was trying to make a cocoon for it self. |
| B．It was crawling around quietly on the ground. |
| C．It was flying among the trees in the forest. |
| D．It was struggling to get out of its cocoon. |
The man cut off the remaining bit of the cocoon in order to __________.
| A．take the butterfly home |
| B．help the butterfly come out easily |
| C．kill the butterfly |
| D．stop the butterfly growing bigger |
What do you think of the man?
| A．Patient but cruel | B．Careful and wise |
| C．Kind but unwise | D．Brave and funny |
What does the last paragraph (段落) tell us?
| A．Struggles are sometimes necessary in our life. |
| B．Nothing is difficult if we put our heart into it. |
| C．Every good deed will come back with good result. |
| D．The greatest happiness in the world is to help others. |
What is the best title of the story?
| A．The Love for the Cocoon. |
| B．The Joy of Helping Each Other. |
| C．The Lesson of the Cocoon. |
| D．The Expectation (期待) for the Butterfly. |
