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.

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.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

4.This passage is probably a ___________.

A. book review????????????? ????????????? B. fiction novel????????????? ????????????? C. fairy tale????????????? ????????????? D. science report

My interest in Chinese food started many years ago, when I had my first job. I was a young reporter for the Daily Journal in San Francisco. Our office wasn’t far from Chinatown. I usually managed to arrange my time so that I could go there at least two or three times a week for a good meal.

The first time I ever ate Chinese food I loved it. And since then, it just tastes better and better to me. The first thing I noticed was the fresh tastes of the meat and vegetable. When I learned more about the food, I began to understand why it has this special feature.

 About 5000 years ago, China lost much of its wood because of over population and poor management of its forest. This loss was very bad for the country, of course, but it turned out to be very good for the food. Wood became very expensive and hard to get, so the Chinese had to learn how to use it better.

 In order to use less wood in cooking, they started to cut their meat and vegetable into small pieces before they put them in the hot oil. That way, the food cooked faster and they saved their fuel. The food prepared in the manner kept its fresh flavor(风味)--- and its this flavor that attracts people to the art of Chinese cooking.

 I often wonder if the Chinese appreciated their solution to that ancient energy problem as much as I do now --- whenever I eat Chinese food.
