【正文】 r. 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(波長(zhǎng)). It reaches our brain(大腦) through organs(感覺器官)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.( )31. Which is the lightest colour in a man’s mind? A. Red B. Blue C. Green D. White( )32.

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.( )35. How much did Myers’ students pay for the rain forest they bought? A. $25 B. $75 C. $80 D. $2000( )36. What did Myers and his students do at the beginning of the trip? A.
