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.

Everyone knows that the French are romantic, the Italians are fashionable and the Germans are serious. Are these just stereotypes(陈规) or is there really such a thing as national character? And if there is, can it affect how a nation succeeds or fails?
At least one group of people is certain that it can. A recent survey of the top 500 entrepreneurs(实业家) in the UK found that 70 percent felt that their efforts were not appreciated by the British public. Britain is hostile to success, they said. It has a culture of jealousy(嫉妒). As a result, the survey said, entrepreneurs were “unloved, unwanted and misunderstood”. Jealousy is sometimes known as the “green-eyed monster(怪物)” and the UK is its home. Scientists at Warwich University in the UK recently tested this idea. They gathered a group of people and gave each an imaginary amount of money. Some were given a little, others a great deal. Those given a little money were given the chance to destroy the large amounts of money given to others—but at the cost of losing their own. Two thirds of the people tested agreed to do this.
This seems to prove the entrepreneurs were right to complain. But there is also conflicting evidence. The Organization for Econnomic Cooperation and Development(OECD) recently reported that the UK was now the world’s fourth largest economy. That is not bad for people who are supposed to hate success. People in the UK also work longer hours than anyone else in Europe. So the British people are not lazy, either.
“It’s not really success that the British dislike,” says Carey Cooper, a Professor of management at the University of Manchester Institute of Science and Technology. “It’s people using their success in a way that seems arrogant(傲慢) or unfair or which separates them from their roots.”
Perhaps it is the entrepreneurs who are the problem. They set out to do things in their way. They work long hours. By their own efforts they become millionaires. But instead of being happy they complain that nobody loves them. If they were more friendly, people would like them more. And more people want to be like them.
56. What does the underlined word “it” in the second paragraph refer to?
A. One group of people. B. A great survey.
C. National character. D. A nation.
57. Most of the British top entrepreneurs surveyed believe that ________.
A. they are not popular simply because they are successful
B. the British public are hardworking
C. love of success is Britain’s national character
D. they are considered as “green-eyed monsters”
58. What does the result of the Warwich University test show?
A. Two thirds of the people tested didn’t love money.
B. Most people would rather fail than see others succeed.
C. An imaginary amount of money does not attract people.
D. Most people are willing to enjoy success with others.
59. The writer of the passage seems to suggest that _______.
A. jealousy is Britain’s national character
B. British entrepreneurs are not fairly treated
C. the scientists at Warwich University did a successful test
D. the British dislike the entrepreneurs because they do not behave properly
When New York City was not very big, there was a market on the East River. On market day all the farmers came there to sell their vegetable, butter and eggs, and fruit. They laughed and talked together, so no one could hear the river that ran beside them.
But Hans ,the butterman , sat without a smile. He sold pounds of butter from a table beside him. Many people said that his butter wasn’t the right weight. They said that his rolls of butter didn’t weigh as much as a pound.
Once the weighmaster came walking down the road. He was looking for people who did not sell the full weight. Someone told him, ”Watch Hans, the butterman.”
Hans had good eyes. He saw the weighmaster and quickly put the piece of gold into the first roll of butter, between the butter and its cover.
A captain was standing beside Hans’s table, and he had seen Hans put the piece of gold into the roll. He stood at Hans’s side when the weighmaster came up to him.
“Good morning,” said the weighmaster.
“Good morning,” said Hans. “I think that you are looking for farmers who trick the people of our town.
“I’m,” said the weighmaster. “Someone told me that your rolls of butter don’t weigh a full pound.”
“Oh yes, they do. Here, Weighmaster. Here is a roll of butter. Weigh it yourself,” said Hans.
Hans took the first roll of butter and gave it to the weighmaster.
The weighmaster took his scales and put the butter onto it. The roll weighed more than a pound.
“I’ve made a mistake,” said the weighmaster. “You are an honest man. There is enough butter in this roll.”
Then the captain stood in front of Hans’s table. “You are an honest man, so I want to buy some of your butter,” he said. Before Hans could speak, the captain picked up the roll of butter with the piece of gold in it. “I’ll take this one.”
Hans’s heart began beating more quickly. “No, not that one. I’ve sold that one to a friend of mine. Take another one.”
“No, I want this one,” said the captain.
“I won’t sell it to you. I told you that I’ve sold it to a friend,” said Hans.
“Don’t make me angry. The weighmaster weighed this roll. Give your friend another one.”
“But I want to give him this one,” said Hans, who was now very uncomfortable.
“I ask you, good Weighmaster,” said the captain angrily, “don’t I have the right to choose the piece of butter that I want? I will pay good money for it.”
“Of course you have the right, Captain,” said the weighmaster. “What are you afraid of, Hans? Aren’t all the rolls of butter alike? Perhaps I have to weigh all of them.”
What could Hans say? What could he do? He had to smile and sell the butter to the captain. The captain gave Hans three cents for the butter.
The captain and the weighmaster walked away together.
“You punished the thief,” said the weighmaster.
“No, he punished himself,” said the captain, smile.
1. When Hans saw the weighmaster, he ____________________ .
A. stood up at once B. said hello to the weighmaster
C. put a piece of gold into a roll of butter quickly
D. gave the weighmaster a piece
2. After the weighmaster weighed the roll of butter that Hans gave, he_________________.

When landing on Copenhagen Tasstrup Airport, you can see numbers of white propeller generators standing in the blue waterfront. The constant moving paddles are producing renewable energy to the city. During the recent Climate Change Conference, the city was introduced to the world as an example of climate-friendly city. Evidences other than wind power stations were obvious everywhere.
While private cars can be a great source of pollution in other cities, the main form of transport in the capital of Denmark is, however, public transportation. By public transportation, I mean one of very good quality. Buses are usually Volvo and most of the traffic lights are of Siemens. Additionally, buses, metros and intercity-trains (named S-train) are well equipped, constantly maintained, special and good-looking. The seats in the trains are of sofa-designed. Sticky gum or dirty spot rarely appear. Thanks to a small population, it is much easier to maintain the condition of the vehicles. Free wireless internet service is provided in S-trains. Seats are always possible even at rush hours if the passenger is patient enough to look for it. Taking the convenience for granted, Danish people find it hard to imagine how the metro in Tokyo can be as crowded as a “sardin can”. Pets and baby-wagons are allowed in buses, subways and S-trains. All the facilities enable better service to bigger passenger group. It is also notable that the mass transit uses green fuels and electricity.
Cars are common in Copenhagen, but people have an alternative of short distance transport: bikes. Denmark is known as bike-friendly for many reasons, such as flat land, splendid cycle ways, and the Danish fond of motion. But please be aware that riding a bike in Copenhagen is not like biking in Beijing. First of all, it is quite speedy. Many people ride to work every morning. Punctuality is important and they have to ride as fast as possible to be on time. So why not speed up? Not my philosophy. As a result, I am often hastened by impatient riders who unfortunately piled up after me. Second, considering the speed, bike helmets, front and back lights and other necessary accessories are required. Riders need to set a white light in the front of the bike and red light at the back. One may end up with a big fine if not riding with them.
72. In the passage we get to know that _____.
all energy come from wind power stations
different kinds of green energy keep this city running
a lot of electricity is imported from other countries
people in this city use little energy
73. S-trains are a kind of transportation______.
A. which send their passengers from one city to another.
B. which uses wind to run their ways
C. which is the only way for you to go from one city to another.
D. which you are not allowed to take if you take a pet.
74. In the last paragraph what does “Punctuality” mean?
A. Being fit B. Not being scolded C. Not being late D. Speeding
75. In Copenhagen if you ride too slow ,_____
A. you will be fined by police.
B. it means that you need to buy a better bike.
C. you may block the traffic flow.
D. many bike riders will shout at you.
