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 temperature will fall. That means our body temperature will change with different colours.

（1）、Paragraph 1-3 tell us that ___________.

A、the two boxes have the same weight B、colours can change the weight of an object C、the red paper is heavier than the white paper D、colours have different weight in people's mind

（2）、Why did the scientist think that colours have smell?

A、Because we can smell colours with our nose. B、Because every colour has its own sweet smell. C、Because people can sense the light from colours D、Because every colour can give off light of the same length.

（3）、Which of the following is NOT true according to the passage?

A、People may get ill if they refuse the colours they don't like. B、People can stay longer in blue rooms than in red rooms. C、In people's mind, red colour is heavier than white colour. D、People's body temperature will change with different colours.

（4）、What is the Chinese meaning of the underlined word “wavelength”?

A、波浪 B、色彩 C、频率 D、波长

（5）、The passage is probably _________.

A、a short novel B、a news report C、a science report D、an advertisement

In 1620, about half the USA was covered by forests. Today the forests have almost gone. A lot of good land has gone with them, leaving only sand. China doesn't want to copy the USA's example. We're planting more and more trees. We've built the " Great Green Wall" of trees across northern part of our country. The Great Green Wall is 7,000 kilometres long, and between 400 and 1,700 kilometres wide. It will stop the wind from blowing the earth away. It will stop the sand from moving towards the rich farmland in the south. More "Great Green Walls" are needed. Trees must be grown all over the world. Great Green Walls will make the world better.

   Want to save the environment? You probably can't fix everything on your own, but by taking small steps and keeping the environment in mind every day, you can make a difference,
     1. Think Green. Challenge yourself to think about the environment as you live your life. If you shut off lights when you leave the room, turn off your TV when you're not watching it, you'll save energy. If you take shorter showers, you'll save water.
    2. Shop Green. Shopping is fun, but buying things you don't need is wasteful and bad for the earth. Before you buy something, ask yourself how much you'll really use it. Keep yourself away from buying products with unnecessary packaging (包装), and whenever possible, buy things that were locally made instead of those shipped from far away.
    3. Dress Green. Wear green trousers and T-shirts if you want. But what really matters isn't the colour, it's how the clothes were made. If you want to help the environment, the best place to find clothes is at a vintage store, but you might not want to buy everything used. No matter where you shop, keep an eye out for products made from environmentally friendly materials like organic(有机的) cotton, which is grown without the use of pesticides ( 杀虫剂).
    4. Study Green. What's better than learning about the environment? Save it while you learn, It can be as simple as using both sides of a piece of paper before you recycle it, or reusing an old textbook :instead of buying a new one. If you want to do more, join an environmental group at your school, and encourage your friends to join, too.

There are many wetlands（湿地） in China and some of them have become the world‘s important wetlands. The Chinese Yellow Sea Wetlands are among them. They are in Yancheng， Jiangsu Province. They are home for many different kinds of birds and animals. The world's largest Milu Deer Nature Reserve（自然保护区） is in them. More than 700 milu deer live freely there. There are not many red-crowned cranes in the world， but every winter you can see some in the Red-crowned Cranes Nature Reserve in the Yellow Sea Wetlands.
The temperature in the wetlands is usually neither too high nor too low. There is a lot of rain and sunshine， too. They are really good places for wildlife（野生生物）。 Offering food and home for some special kinds of animals and birds is not the only reason why we need to protect wetlands. Wetlands are important because they also prevent flood. But some people want to change the wetlands to make more space for farms and buildings. This means there will be less and less space for wildlife.
Luckily， more and more people are beginning to realize the important of wetlands and wildlife. Every year， on February 2nd， many activities are held to tell people more about wetlands.

    Many of us don't pay attention to the importance of eye care. It's said that if you take care of your body, then you can be healthy. That is why our eyes should be given a lot of care. Natural eye care should be put in a number one place.
    There are several causes leading to poor eyesight like not enough food, gene(基因) and aging(年龄增长). Televisions, computers and reading are also the causes of having poor eyesight.
    If you happen to work in front of the computer, it is best to take a rest every once in a while. Something dirty can cause redness and they will make you feel uncomfortable. It is bad for your eyes, too. If this happens, the best way is to clean your eyes by using cold water. You must also try your best to protect your eyes from harmful thing. For example, sunglasses are not just fashion but they can also serve as a great way to protect your eyesight from UV rays.
    Eating healthy foods will do good to your eyesight. Remember that vitamins(维生素) A、C and E are good for eyes. Try to eat food groups that have these vitamins. And you should do eye exercises because exercise protects your eyesight, too. If a person exercises regularly(规律地) and eats the right kind of food, his eyes will stay in good condition for a long time.
    All above are natural ways of eye care that help us keep healthy eyes. Being happy all the time can be helpful to a person's eyesight, too. In a word, eye care is very important, no matter how old a person is.

根据短文内容的理解,选择正确答案。

When the weather is hot, you go to a lake or an ocean. When you are near a lake or an ocean, you feel cool. Why? The sun makes the earth hot, but it can not make the water hot. Though the air over the earth becomes hot, the air over the water stays cool. The hot air over the earth goes up, then the cool air over the water moves in and takes the place of the hot air. When you are near a lake or an ocean, you feel the cool air when it moves in. You feel the wind and the wind makes you cool.

Of course, scientists cannot answer all of our questions. If we ask "Why is the ocean full of salt?" scientists will say that the salt comes from rocks. When a rock gets very hot or very cool, it cracks (崩裂), and rain falls into the cracks. The rain then carries the salt into the earth and the rivers. The rivers carry the salt into the ocean. But then we ask "What happens to the salt in the ocean? The ocean does not get saltier every year." scientists are not sure about the answer to the question.

We know a lot about our world. But there are still many answers that we do not have, and we are curious(好奇的).
