We live in the world full of colours. Does a colour have weight? If you say “no”, you are wrong. If you don’t believe, you may do an experiment.

First, put two objects with the same weight into two boxes. Then cover the boxes. Third, wrap one box with a red piece of paper, the other woth a white piece of paper. Now hold the boxes with your hand one by one. It is certain that you think the red one is a little heavier.

Why? A scientist found that different colours have different weight in a man’s mind. So he did many tests and at last he found that every colour has its own weight in our mind and their order is the same. The heaviest colour is red, then blue, green, orange, yellow and white.

The scientist told us that colours also have smell. Can you smell the colour? Of course not. Then why did the scientist say so? That is because every colour stands for a kind of light with a certain wavelength, and it reaches our brain through sense organs.

According to this discovery, scientists say that people accept the colours they like, and refuse the colours they hate. So your body and mind will be healthy by using the colours 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 tempertature will fall. That means our body temperature will change with different colours.

It takes much time to learn a language. There are many reasons to learn a language.

Emigration

When you move to a different country or region, learning the local language will help you to communicate with the local community. Even if many local people speak your language, it’s important to learn their language. It will also give you a better understanding of their culture and way of thinking.

Work

If your work is about languages, talking to them in their own languages will help you to communicate with them. Knowing languages may also increase your chances of finding a new job, getting a promotion or a transfer overseas, or of going on foreign business trips.

Many English-speaking business people don’t bother to learn other languages because they believe that most of the people they do business with in foreign countries can speak English. The lack of foreign language knowledge puts the English speakers at a disadvantage.

Travel

When you go on holiday you can get more information by speaking English. If people don’t understand you, all you have to do is speak slowly and turn up the voice.

Food

Perhaps you enjoy the food and drink of a country or region and make trips there. It is very useful to learn a foreign language.

1.The underlined word “chance” means .

A. opportunity B. interest C. instruction D. explanation

2.There are reasons to learn a language in the passage.

3.What is NOT true according to the passage ?

A. It’s important to learn a foreign language when moving to a different country.
