You must think a computer is the best thing in the world, right? You must think it works at a super speed and can do everything? Well, it's not! In fact,the brain is much more powerful than any super computer! Think about when a glass is just about to fall off the table.Your brain controls everything that you need to do to save that glass from falling. First your eyes check out what 's going on, then tell your brain. and your brain decides how quickly you need to react (反应), and then your muscles (肌肉) go into action. That is just from your brain. No computer could ever come close to that!

    The brain weighs just 3 pounds, but it controls everything you do from thinking, learning, feeling even to breathing and your heart beating. Even though the brain is just 2% of your body weight, it uses around 20% of all your energy in your body. That is a lot for such a small organ (器官). There are about 100 billion tiny, tiny little cells (细胞) in your brain. There are so many that it would take you over 3.000 years to count them all!

    Your brain stops growing when you're 18, but it actually keeps on developing and learning new things. So your parents are really super smart! You won't be able to fool them! Believe it or not, your brain NEVER stops working. Even during sleeping, the brain works for long﹣ term memory establishment (建立). It is realized that the brain is the second organ in the body as the heart that never stops during human lives.

So everyone should be proud of such a gift of nature.

The world is not hungry , but it is thirsty . It seems strange that nearly 3/4 of the earth is covered with water while we say we are short of water. Why? Because about 97% of water on the earth is sea water which we can't drink or use for watering plants directly. Man can only drink and use the 3% - the water that comes from rivers and lakes. And we can't even use all of that, because some of it has been polluted .
  Now more water is needed. The problem is: Can we avoid (避免) a serious water shortage later on? First, we should all learn how to save water. Secondly, we should find out the ways to reuse it . Scientists have always been making studies in the field. Today, in most large cities water is used only once and then runs to the sea or rivers . But it can be used again. Even if every large city reused its water, still there would not be enough. What could people turn to next?
  The sea seems to have the best answer. There is a lot of water in the sea. All that needs to be done is to get the salt out of the sea water. This is expensive, but it's already used in many parts of the world. Scientists are trying to find a cheaper way of doing it. So you see, if we can find a way out, we'll be in no danger of drying up.
The world is thirsty because ________.

A.3/4 of the earth is covered with water
B.we have enough sea water to use directly
C.we haven't used all the water in rivers and lakes

A.3% of water on the earth is in rivers and lakes.
B.75% of water on the earth is the sea.

A.if every city reuses its water, we'll be in no danger of drying up
B.man can only drink and use about 25% of water on the earth
C.today in most large cities water is used only once
D.water can be used only once

B.Don't pollute water and keep all rivers and lakes clean.
C.Make dirty water clean and then reuse it.

A thousand years ago, Hong Kong was covered by a thick forest. As more and more people came to live in Hong Kong, these trees were cut down and burnt. Now there is no forest left, though there are still some small areas covered with trees. We call these woods.
Elephants, tigers and many other animals were living in the thick forest. When people came to live in Hong Kong, the animals began to die out. Early farmers grew rice and kept pigs and chickens in the valleys. They cut down the trees and burnt them. They needed fire to keep themselves warm in winter, to cook their food and to keep away the dangerous animals. Elephants quickly disappeared because there was not enough food for them. Many other animals soon died in the same way.
You might think that there are no longer any animals in Hong Kong except in 2005. But there are still about 36 different animals living there. One of the most interesting of Hong Kong’s animals is the barking deer. These are beautiful little animals with a rich brown coat and a white patch under the tail. They look like deer but they are much smaller. They are less than two feet high. They make a noise rather like a dog barking. In Hong Kong the barking deer has only a real enemy—— men. People hunt these little animals though it is illegal, There are now not many barking deer left. So it is important for people to protect wild animals.
