题目内容

There are many colors in nature. But do you know if a color 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. Third， wrap(包裹) one box with a red piece of paper， the other with a white piece of paper. OK. 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 do you think so? A scientist found that different colors 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 color has its own weight in our mind and their order is the same. The heaviest color is red， then blue， green， orange， yellow and white.

The scientist told us that colors also have smell. Can you smell the color? Of course not. Then why did the scientist say so? That is because every color stands for(代表) a kind of light with a certain wavelength(波长). It reaches our brain through sense organs.

According to this discovery， scientists say that people accept the colors they like， and refuse the colors they hate. So your body and mind will be healthy by using the colors you like. Or you’ll be nervous or even get ill. For example， 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 an 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 with different colors.

1.From the experiment， we know that .

A. the two boxes have the same weight

B. colors can change the weight of an object

A. the smell of colors is changeable(可变的)

B. people can sense the light from colors

C. people can smell the colors through the nose

D. ll the colors have the same smell for the blind

C. People can stay longer in red rooms than in blue rooms

D. People’s body temperature will change with different colors

The word “day” has two meanings. When we talk about the number of days in a year, we are using “day” to mean 24 hours. But when we talk about day and night, we are using “day” to mean the time between sunrise and sunset. Since the earth looks like a ball, the sun can shine on only half of it at a time. Always one half of the earth is having day and the other half night. A place is moved from day into night and from night into day over and over by the spinning（旋转）of the earth. At the equator（赤道）day and night are sometimes the same length. They are each twelve hours long. The sun rises at 6 o’clock in the morning and sets at 6 o’clock in the evening. For six months the North Pole is tilted（倾斜）toward the sun. In those months the Northern Hemisphere（半球）gets more hours of sunlight than the Southern Hemisphere. Days are longer t han nights. South of the equator nights are longer than days. For the other six months the North Pole is tilted away from the sun. Then the Southern Hemisphere gets more sunlight. Days are longer than nights. North of the equator nights are longer than days. Winter is the season of long nights. Summer is the season of long days.

1.When the Western Hemisphere is having day, the Eastern Hemisphere is having ______.

A. both day and night B. day

C. neither day nor night D. night

2.A place is moved from day into night and from night into day over and over by _____ of the earth.

Would you like to adopt(收养) an animal? Although this sounds very unusual, some children have done just this. The Natural Zoo has given people the chance to adopt animals by paying for all of its food for one year. One of the animals that needed parents was a young tiger named Brocky. The people at the zoo said that it would cost about $900 a year for the food for Brocky.

Not many boys and girls have $900 to spend. That is why several hundred children and grown-ups(成年人) each have sent a little money to the zoo to help pay for Brocky’s food. Some children sent in only a quarter because that was all the money they had. Other children sent in more money than that.

Since so many people sent money to the zoo to help pay for Brocky’s food, he now will be able to eat as much as he wants. Brocky surely must be a happy tiger to know that he has so many adopted parents. Many children must also be happy to know that they have helped to feed him. It really will be thrilling(令人兴奋的) for those children to go to the Natural Zoo to visit their adopted tiger Brocky.
