Science and technology are developing quickly. On the one hand they can improve our lives, but on the other hand, they can cause pollution.
Air pollution is a serious problem. Factories and heavy traffic give out a lot of smoke and make the air dirty. So the government should take action and make everyone keep the air clean.
The main reasons for noise pollution are heavy traffic and road works. Therefore, the government should try to make less noise.
Factories put a lot of dirty water and chemicals into the rivers and the sea. They pollute the water. And it also can make sea animals sick. So the government should stop factories doing that.
The main reasons for land pollutions are construction and people. Construction makes much waste and people throw away a lot of rubbish every day. People should stop throwing away so much rubbish and start using old things again.
Mike Myers is a teacher at Chauncey Rose High School in Terre Haute, Indiana. Last year, he taught his students about the world’s rain forests. They learned that rain forests are important because the plants and animals of the rain forest give us food, wood, and medicine.
Destruction of the world’s rain forests is a serious problem. Unluckily, rain forests are disappearing at a rate of 80 acres per minute! As part of a class project, Myers’ students bought three acres of rain forest in Central America. They paid $25 per acre. The students hope that the land they bought will be protected and not destroyed. The students became so interested in rain forests that they decided to get a closer look at a real rain forest.
So last June, Myers and four of his students took a boat ride down a river. They saw alligators and crocodiles. In the middle of the week, a guide took Myers and his students into the rain forest. “The monkeys were not happy that we were in their forest. They broke small branches off the trees and threw them at us,” one of the students said, “It was a great learning experience for all of us,” said Myers.
Each student chose something specific about Costa Rica to study involving the plants, animals, food, and culture. During the last few days the group had time to do fun activities. They went whitewater rafting and horseback riding, and visited Costa Rica’s active volcano.
Myers hopes to make the trip every year with a different group of kids.

There are many colours in nature. But do you know that a colour has weight? I think you’ll say “no”. But I am afraid you are wrong. If you don’t believe, you may do a small experiment(实验).
First, put two objects with the same weight into two boxes. Then cover the boxes. Wrap(包裹) one box with a red piece of paper, the other with a white piece of paper. Now hold the boxes with your hand one by one. It is certain that you will think the red one is a little heavier.
Why does it happen? A scientist found that different colours have different weight in a man’s mind. So he did many tests and at last he got the result. That is to say, every colour has its own weight in our mind. The heaviest colour is red, then blue, green, orange, yellow and white. The scientists told us that colours also have smell. Can you smell the colour? Of course not. Then why did the scientists say so? That is because every colour represents a kind of light wave(光波)------ a certain wavelength(波长). It reaches our brain(大脑) through organs(感觉器官)
According to this discovery, scientists say that people accept the colour they like, and refuse the colour they hate. So your body and mind will be healthy by using the colours you like. Or you’ll be nervous or even get ill. If you stay in a room with red windows, wallpapers and furniture(家具) for two hours, you’ll feel you have been there for four hours. But if the room is blue, you’ll feel you have been there for only one hour. Another example, if a person walks out of a red room and into a blue room, his temperature will fall. That means our body temperature will change when we see different colours.Which is the lightest colour in a man’s mind?
| A．Red | B．Blue | C．Green | D．White |
Which of the following is NOT true?
| A．Different colours have different weights in a man’s mind. |
| B．The colour “blue” is the second heaviest colour in a man’s mind. |
| C．People can’t smell the colours. |
| D．The colour you don’t like will keep you healthy. |
What will happen when you get into a cool coloured room from a warm coloured room?
| A．You will feel excited. |
| B．You will be happy and contened. |
| C．Your temperature will fall. |
| D．You will be nervous. |
According to the passage, how long will you feel if you stay in a red room for an hour?
| A．Two hours. | B．Fours hours |
| C．Six hours | D．Eight hours. |
