There are many colors in nature. But do you know if a color has weight? I think

题型:不详难度:来源:
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.
小题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
小题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.
小题3:It can be implied from the text that ___________.
A.colors have orders in weight
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
小题4:This passage is probably a ___________.
A.book reviewB.fiction novelC.fairy taleD.science report

答案

小题1:B
小题2:A
小题3:D
小题4:D
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。
小题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。
小题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。
小题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。
小题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。

Imagine the situation. You are driving in a village or on a mountain. You have no idea where you are. You passed the last house two hours ago. Then your car doesn’t work. It is night and it is cold. You have no mobile phone. What do you do? Well, next time take a GPS with you. This invention may be able to help you. It is used for finding your position(位置) with the help of satellites (卫星). A GPS can’t start your car, but at least you will know where you are.
GPS, which means Global Positioning System(全球定位系统), is a small radio receiver. It looks like a mobile phone. You can hold it in your hand, or put in your pocket. It is sometimes put into a watch or a telephone. We also find a GPS in cars, planes, or boats. Some of them have electronic maps, so you know where you are. For example, in a city they can tell you the name of the street.
There are three parts to GPS. The first part is the receiver. You can hold it in your hand, or have it fixed into your car, plane, etc. The second part is a group of satellites going around the Earth. The receiver communicates with at least four of the satellites and calculates its position. The third part of the system is a network of ground stations all over the world. They control (控制) the satellites and make sure they are working well.
Some people think that in the future the GPS will be as common as the mobile. They are becoming better and cheaper. There are also new uses for the GPS. Perhaps they will become like watches. Everyone will have one and you will never be lost again.
小题1:According to the passage, with the help of the GPS, people __________.
A.can’t be lost in a new city
B.can’t find their way in different countries
C.can learn about the culture of an unknown place
D.can spend the least time getting to another place
小题2:We can learn from the passage that ____________.
A.there are three parts to the GPS
B.a GPS can’t be put into a watch
C.a GPS can help you start your car
D.the GPS are becoming more and more expensive
小题3:The underlined word “They ” in paragraph 3 means “____________”.
A.ReceiversB.GPSC.SatellitesD.Ground stations
小题4:What can we infer(推断) from the passage?
A.All GPS devices have electronic maps.
B.People in many countries will use the GPS for free.
C.The receiver of the GPS communicates with at least five of the satellites.
D.The GPS will become more and more common in everyday life.
