There are many colors in nature. But do ...

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 man 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 (感觉器官).

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.

1.The purpose of the second paragraph is to tell us ___________.

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.

3.If a person walks from a blue room to a red room, his body temperature will _________.

A. rise           B. fall

C. stay the same  D. change now and then

4.This passage is probably a ___________.

A. book review(评论)  B. fiction novel

C. fairy tale          D. science report

 

1.B 2.A 3.A 4.D 【解析】 试题分析:这篇短文主要是通过一个实验来告诉人们颜色是有重量的,同时文中指出颜色是有气味的。 1.B段意归纳题。通读第二自然段,很容易理解该实验的四个步骤:首先是将两个重量相同的物体分别放进盒子里。然后将盒子盖上。接下来用一张红色纸将其中的一只盒子包上,另一只盒子用白色的纸。最后是将这两个盒子放在手中掂一掂。由此可得答案是B,颜色是有重量的。 2.A细节理解题。第四自然段首句的“The scientist told us that colors also have smell.”这句话中。可知答案是A。 3.A推理判断题。从最后一段的句子:Another example, if a person walks out of a red room and into a blue room, his temperature will fall.可知从蓝色房间进入红色房间,体温会上升。选A。 4. 考点:考查科普类短文阅读

Not everyone has a chance to be a detective(侦探), but I got one when I was 13 years old. It happened in 1993.

One afternoon, I was walking down the street when I saw my father's new car. I expected to see my father in the driver's seat. but to my surprise, I saw a young woman driving instead, "She has stolen my father's car," I thought. So I quickly stopped a taxi and got in. I said to the driver, "Follow that new car in front," I told him why.

The taxi driver had a car phone, so I asked him to call the police. Soon we heard the sound of a police car. The police told the woman to stop the car using a loudspeaker. The taxi came to a stop, too. I got out right then and said to the woman, "This is not your car. It's my father's car."

The woman smiled and said, "Oh. You're Mr. Johnson's son, right? I've seen your photo in your father's office."

Before I could say one word, the woman explained that she was my father's new assistant. My father had asked her to take his computer to the shop to have it repaired. He lent her his car. After hearing this, I called my father and he told us what the woman said was right. The police and the taxi driver laughed. I felt very sorry. It was both the first time and the last time I worked as a detective.
