A man found the cocoon (茧) of a moth (蛾). He took it home so that he could    1  the moth come out of the cocoon. On that day a small   2  appeared. He sat and watched the moth for several hours as the moth struggled to   3  the body through that little hole. Soon it seemed to stop making any progress. It appeared as if it had    4  as far as it could and it could go no further. It just seemed to be stuck. So the man, out of his kindness, decided to help the moth. He took a pair of scissors and cut off the  5___  bit of the cocoon. The   6  then came out easily. But it had a swollen body and small, shriven (无用的) wings. The man continued to watch the moth because he expected that, at any moment, the wings would enlarge and   7  to be able to support the    8  , which would get smaller in time. Neither happened! In fact, the little moth spent the rest of its life   9  around with a swollen body and shriven wings. It was   10  able to fly.
What the man in his kindness   11  was that the small cocoon and the  12__of the moth to get through the   13  opening was a way to push fluid (液体)   14  the body of moth   15   its wings so that it would be ready to fly   16  it got out of the cocoon. Freedom and    17  would come only after the struggle. By taking the struggle away, he also took away the moth’s health.
Sometimes struggles are exactly what we need in our lives. If we were to   18  our lives without any difficulties, we would become disabled. We would not be as    19  as what we could have been. Give every opportunity a chance. Leave no room for   20   .

A good heart
Dikembe Mutombo grew up in Africa among great poverty and disease. He came to Georgetown University on a scholarship(奖学金) to study medicine — but Coach(教练) John Thompson got a look at Dikembe and had a different idea. Dikembe became a star in the NBA, and a citizen of the United States. But he never forgot the land of his birth, or the duty to share his fortune with others. He built a new hospital in his old hometown in the Congo. A friend has said of this good-hearted man: “Mutombo believes that God has given him this chance to do great things.”
Success and kindness
After her daughter was born, Julie Aigner-Clark searched for ways to share her love of music and art with her child. So she borrowed some equipment, and began filming children’s videos(录像) in her own house. The Baby Einstein Company was born, and in just five years her business grew to more than $20 million in sales. And she is using her success to help others — producing child safety videos with John Walsh of the National Center for Missing and Exploited Children. Julie says of her new program: “I believe it’s the most important thing that I have ever done. I believe that children have the right to live in a world that is safe.”
Bravery and courage
A few weeks ago, Wesley Autrey was waiting at a Harlem subway station with his two little girls when he saw a man fall into the path of a train. With seconds to act, Wesley jumped onto the tracks, pulled the man into the space between the rails(铁轨), and held him as the train passed right above their heads. He insists he’s not a hero. He says: “We have got to show each other some love.”
【小题1】 Mutombo believes that building the new hospital is ______.

A Battery’s Nightmare
Portable electronics that can be carried about easily are only as good as their batteries (电池) and, let’s face it, batteries aren’t very good, especially when compared with, say, petrol, which packs 100 times a battery’s energy into an equal space. That’s why a large group of mechanical engineers (centered at the Massachusetts Institute of Technology, but with partners at other universities and companies) are hard at work in an effort to replace batteries with a tiny engine that runs on fuel. Imagine a battery-free life! When the fuel runs out in your mobile phone, you just fill up and go.
The engine---about the size of a ten-cent coin---starts with a combustion chamber (燃烧室) that burns hydrogen. Its tiny parts are etched (蚀刻) onto silicon wafers (硅片) in the same manner that computer parts are etched onto integrated circuits (集成电路). The first engine is made up of five wafers. And since these wafers could be produced in much the same way as computer chips, they could probably be produced quite cheaply.
But the devil in all this nice detail is efficiency. Tiny engine parts don’t always behave like the bigger parts of the first engine. Something between the parts can slow down the works, according to Columbia University Professor LucFrechette, one of the engine’s designers. Extreme heat from the combustion chamber is also a problem, often leaking to other parts of the engine.
The scientists’ goal is to create an engine that will operate 10 times better than batteries operate. Frechette says that a complete system, with all parts in place and working, will be set up in the next couple of years, but commercial models aren’t likely until at least the end of the next ten years.
【小题1】According to the passage, the title suggests that _______ .

A butcher watching over his shop was really surprised when he saw a dog coming inside the shop. He went over to the dog and noticed it had a note in its mouth. He took the note and it read “Can I have 12 sausages and a leg of lamb, please. The dog has money in his mouth, as well.”
The butcher looked carefully and was surprised to find that there was really a ten-dollar note there. So he took the money and put the sausages and lamb in a bag, placing it in the dog’s mouth. The butcher was so impressed, and since it was about closing time, he decided to shut up shop and follow the dog.
So off he went. He followed the dog to a bus stop. The dog stopped and started looking at the timetable. The dog checked out the time, and then sat on one of the seats provided. Along came a bus. The dog walked around to the front, looked at the number, and went back to its seat. Another bus came. Again the dog went around to the front, looked at the number and climbed on. The butcher, by now, open-mouthed, followed it onto the bus.
The bus traveled through the town and out into the suburbs. Eventually the dog got up, and moved to the front of the bus. It stood on two back paws and pushed the button to stop the bus. Then it got off with groceries still in its mouth.
Well, the dog and the butcher were walking along the road, and then the dog turned into a house. It walked up the path, and dropped the groceries on the step. Then it walked back down the path, took a big run, and threw itself against the door. Then again, it threw himself against it. There’s no answer at the house. so the dog waited at the door.
The butcher watched as a big guy opened the door, and started shouting at it. The butcher ran up, and stopped the guy. “Why do you shout at the dog? It is really a genius.” The guy responded, “You call this clever? This is the second time this week that this stupid dog’s forgotten its key.”
