There are many colors in nature.But do you think that a color has weight? I think you'll say “no”. But I'm afraid you are wrong. If you don't believe it, 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(色裹) one box with a red piece of paper, the other one 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 weights in man's mind. That is to say, every color has its own weight in our mind.

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,  you like blue and hate red.If you stay in a room with red windows, wallpaper 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. And, if a person walks out of a blue room and into a red room, his temperature will rise.

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

C.the red paper is heavier than the white paper

D.colors have different weights in people's mind

2.From the fourth paragraph, we can infer ____.

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.all the colors have the same smell for the blind

3.Which of the following is true?    ____.

A.White color is heavier than red color

B.People may get ill if they refuse the colors they don't like

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

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

4.We can infer from the last paragraph that____.

A.red color is bad for our health

B.people may get nervous in a red room

C.blue color can raise(提升)our body temperature

D.colors can influence our mood(情绪)and health

5.The passage is probably ____.

A.a short novel        B.a news report

C.a science report     D.an advertisement

 

1.D 2.B 3.D 4.D 5.C 【解析】 试题分析:短文大意: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.D 细节理解题。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D,颜色是有重量的。 2.B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B。 3.D细节理解题。根据文中最后一段That means our body temperature will change with different colors.这意味着我们的体温会随着不同的颜色而改变。可知该选D。 4.】D细节理解题。根据文中So your body and mind will be healthy by using the colors you like.Or you'll be nervous or even get ill.可知颜色可以影响我们的情绪和健康。所以该选D。 5.】C细节理解题。这是一篇科普文章,应该出现在科学报告中。选C 考点:考查科普类短文阅读。

Next time you’re in a public place, take a look around you, and count how many people are using their phones. I can tell you that it is probably more than half, whether you’re in a bus, in a café or simply walking down the street.

I’m not saying that I am not an example of this, but I wonder how people can spend so much time on their phones without actually talking to anyone in particular. We can now do almost anything with a phone. But has it gone too far? We spend too much time on our mobiles but not enough time talking to people in real life.

Last time I visited London, I traveled by subway. I noticed that almost everybody else

was on their phones except those who were asleep. People were playing games, reading articles and listening to music.

Recently, my smart phone broke and I had to use an old basic phone just to keep in touch with my family and friends. I could only send text messages, make calls and play one game with it. And I loved it. I loved being free from the Internet, and I really didn’t mind what my friends were doing or what the latest news was. I could enjoy my time watching the people around me and seeing what was going on.

However, I  knew that as soon as I got my smart phone back, I would be one of those people once again.

1.The writer finds that _________ people are using their phones in public places.

A. most      B. few        C. half       D. all

2.Which of the following cannot be done on a phone?

A. Playing games.      B. Sending text messages.

C. Listening to music. D. Having meals.

3.The writer could use his old basic phone to __________.

A. surf the Internet

B. watch the people around him

C. play one game

D. look through the latest news

4.What didn’t the writer see on the subway when he visited London?

A. People were sleeping.

B. People were talking with each other.

C. People were playing games.

D. People were using their phones.

5.From this article, we know that __________.

A. everybody was on their phones when the writer traveled in London by subway

B. most people spend enough time talking to people in real life

C. the writer enjoyed his time without his smart phone

D. the writer won’t use his smart phone any more

One day Frank was walking with his mother when they came to a pretty garden. Frank looked in, and saw that it had clean gravel (碎石) walks and beautiful flowers. He called to his mother and said, Mum, come and look at this pretty garden. I wish I might open the gate, and walk in.” The gardener (园丁) heard what Frank said, and kindly invited him and his mother to come into the garden.

Franks mother thanked the man.Then she said to her son, “Frank, if I take you to walk in this garden, you must take care not to meddle (乱动) with anything in it. Frank walked along the tidy gravel walks, and looked at everything, but touched nothing that he saw. He did not step on any of the borders(草坪边的狭长花坛),and was careful that his clothes should not brush the tops of the flowers so that he might not break them.

The gardener was much pleased(满意的)with Frank, because he was so careful to behave well.He showed him the seeds, and told him the name of many of the flowers and plants.

While Frank was admiring the beauty of a flower, a little boy came to the gate, and finding it locked, he shook it hard.But it would not open.Then he said, “Let me in.Let me in.Will you not let me in this garden?

“No, said the gardener, I will not let you in, Tom.When I let you in yesterday you meddled with my flowers, and pulled some of my fruit. I do not choose to let a boy into my garden who meddles with the plants.

Tom looked ashamed, and when he found that the gardener would not let him in, he went away slowly. Frank saw and felt how much happier a boy may be by not meddling with what does not belong to him.
