Question

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.

First, put two objects with the same weight into two boxes. Then cover the box. Third, wrap 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 a kind of light with a certain wavelength. 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 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.

A. a red box is heavier than a white one

B. a color has weight in one’s mind

C. white paper is lighter than red paper

D. you can know the weight of a color by holding it

2.Why did the scientist say colors have smell?

A. Because people can sense the light from colors.

B. Because we can smell colors with our nose.

C. Because every color has its own sweet smell.

D. Because every color can give off light of the same length.

B. colors can change the weight of an object

C. people would stay longer in a room with red windows

D. colors can affect our mood and health

【解析】

试题分析：这是一篇科普读物。颜色真的有轻重、有气味吗？科学家解释说人们感觉颜色有轻重是因为我们的思维定式而已，人们感觉颜色有气味是因为每种颜色代表一种有特定波长的光而已；但人们可以接受自己喜欢的颜色，充分利用自己喜欢的颜色。

1.细节理解题。第二段话介绍你用一个小实验来感受颜色的重量，但现实生活中颜色是没有轻重的，只是我们自己的感觉而已；而且在第三段中也说到颜色只是在我们的思维中有了轻重。所以应该选B。

2.细节理解题。短文第四段说到：That is because every color stands for a kind of light with a certain wavelength. It reaches our brain through sense organs.那是因为每一种颜色代表一种有一定波长的光，它经过感觉器官到达我们的大脑。所以应选A。

3.细节理解题。这个题目可以用排除的方法来做。很显然A、B是不正确的，从最后一段可以看出人在红颜色的房间会感觉时间长了，这也是感觉而已。所以A、B、C都要排除，只能选D。

4.细节理解题。短文多次提到科学家发现颜色有轻重、颜色有味道，所以这是一篇科普小短文。故选D。
