阅读短文，然后从每小题A、B、C、D中选出能回答所提问题或完成所给句子的最佳答案。

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.

     Most of you know this mathematical game, of course. You and your friend draw crosses and circles on a sheet of paper. You do it one after another. The first pupil who gets three marks in a row wins. But do you know that you can play this game another way and it will become more interesting? You must try to make your friend win. If you get your three marks in a row, you don't win — you lose!

     It is more difficult to play this game the other way. The second pupil can always win (if he plays the right way), but he may not win if the first pupil begins with his mark in the center. Then if the first pupil always takes a place on the other side of his friend's mark, nobody will win.
     If your friend does not know the secret which we have explained, you must play each time so as to leave him the greatest number of ways to win. You may try a few games and you will see how interesting it is to play the game this way.

    Everybody hates rats. But rats may soon be man's new good friend.
    What happens after an earthquake? We send in rescue(援救)dogs. Why? Because they can smell people. Dogs save lives. They help rescuers to find living people. But dogs are big and they can't get into small spaces. So now a new research project is using a smaller animal to save lives: the rat.
    How does it work? First, the rat is trained to smell people. When this happens, the rat's brain gives a signal(信号). This is sent to a small radio on its back, and then the rescuers follow the radio signals. When the rat's brain activity jumps, the rescuers know that someone is alive. The rat has smelled that person.
    Although there are already robots which can do this job, rats are better. “Robots' noses don't work well when there are other smells around. Rats are good at that.” Rats can also see in the dark, they are cheaper and quicker to train than dogs, and unlike robots, they don't need electricity!
    The “rat project” is not finished, but a scientist says, “It would be great. A rat could get into spaces we couldn't get to, and a rat would get out if it wasn't safe.” Perhaps for the first time in history, people will be happy to see a rat in a building (but only after an earthquake, of course).

Animals grow up in different ways. Some newborn animals are helpless but their mothers protect them. A newborn kangaroo is very small. It is only a few centimeters(cm) long. It closes its eyes and doesn't have hair. It stays safe in its mother' s pouch(育儿袋) for a long time.A newborn monkey can not walk. Its mother carries it everywhere.

Other baby animals can walk soon after they're born. They learn to run with their mothers when danger is near. A baby zebra can run, an hour after it is born.

Some baby animals are born in a place that is safe. Baby wolves are usually born in big holes with little light. Other baby animals are born in the open. A baby elephant is often born on open land.

Animals that drink their mothers' milk are called mammals. A mother bear's milk is rich. Baby bears have milk for a few months. This is the same with baby zebras. As baby animals grow, they need solid(固体) food. Baby lions eat what their mother can catch!

According to a national study, in the summer of 2013, the long-term(长期的) warm weather in the UK has made the number of butterflies increase.

Around 46,000 volunteers(志愿者) took part in the year's Big Butterfly Count(统计), and they found 830,000 butterflies.Volunteers were asked to make a record.They would record how many times they found one of 21 different kinds of butterflies.

Later, the scientists used the records to find out how many butterflies of different kinds were found across the country.Then, they compared the results to the year before.They found that there was a rise in the number of 15 kinds of butterflies, and some of them went up by 50% compared to recent years.They said the increase in butterfly numbers was a result of warm weather.

However, scientists also said that the number of butterflies was in decline(下降) as a whole, and that we might not see the same result the next year.

Richard Fox, who works for Butterfly Conservation, said, “UK butterflies are in long-term decline.Studies have been done since the 1970s.They show that UK butterflies have declined in type and number.”

He added, “We must halt the long-term decline of these beautiful creatures(生物).The only way is by stopping the damage that has been done to the butterflies' habitats(栖息地) across the UK.”

Animals are our good friends. Some are active and others are quiet. But do you know anything about the clever animals in the world? Just have a look!

Animals	Interesting facts
	Kelly is an African elephant. Now she is 19 years old. She lives in the zoo. Kelly has produced more than 100 paintings since last year. She has made over $3,500 for the zoo. Newspaper reporters wrote about Kelly, and then people went to buy her pictures.
	Nana is a clever black and white dog in England. He can do many things just like a human. He can walk on two legs and close the door. Also, he is able to get things for his master, such as newspapers and the TV remote control. What's more, he can sleep and use the quilt very well. No games are difficult for him!
	Koko is a 44-year-old chimpanzee. He has lived with human for tens of years and can “talk” to humans with his hands. He can do simple gestures and that helps people to understand him.

Do you still get free plastic bags from the supermarkets? Things have changed.

China has banned(禁止) free plastic bags in shops and supermarkets, and people have to pay for using plastic bags. The rule started on June 1st. It came because our country tried to make less litter. Making super-thin plastic bags has also been banned.

The Chinese once used about 3,000,000,000 plastic shopping bags a day, and they have caused the pollution of the environment. The bags have become a main cause of plastic pollution because they are easy to break and people throw them away here and there. So the Chinese people are encouraged to bring their own bags for shopping.

What kind of shopping bag is the best to bring? Some students in Chongqing have a good idea. They make their own shopping bags. They use old clothes to make cloth bags, and send them to their parents as presents. They also ask their parents and friends to use cloth bags instead of plastic ones. They think it is their duty to protect the environment.
