Wash Your Clothes with a Cup of Water?
A washing machine that uses only a cup of water to carry a full wash, leaving clothes completely dry, has been developed by British inventors. Researchers say the technology, which uses less than 2 percent of the water and energy of a traditional machine, could save billions of liters of water each year.
The machine works by using thousands of plastic chips— each about half a centimeter in size—to absorb and remove dirt. Around 20 kilos of the chips are added to each load, along with a cup of water and detergent(洗滌劑). During the washing cycle, the water is heated to help dissolve the dirt, which is then absorbed by the plastic chips. The inventors say the chips should be removed at the end of each wash, but can be used up to 100 times.
The technology, called Xeros, is already being compared to the Dyson bagless vacuum cleaner, which revolutionized the home cleaning industry when it was first introduced to the public in the mid-1990s.
If adopted by many homes across the UK, the machine could save billions of liters of water each year. According to the research, washing machine use has risen by 23 percent in the past 15 years, up from three times a week in 1990 to an average four times now. The average UK household uses most 21 liters of water daily on clothes washing. Nationally, this equals to approximately 455 million liters of water a day — enough to fill 145 Olympic-sized swimming pools.
Although the Xeros is now in the design and testing stage, the inventors say they are in talks with a commercial partner. The machine could be in the market as early as next year. Tests have produced quite astonishing results. “We’ve shown that it can remove all sorts of everyday stains including coffee and lipstick while using a tiny fraction of the water used by traditional washing machines,” said one of the inventors.
An expert said, “This is one of the most surprising and remarkable technologies I’ve had in recent years. Xeros has the ability to save billions of liters of water per year and, we believe, the potential to revolutionize the global laundry market.
64. Compared with the traditional washing machine, the most outstanding feature of the Xeros is that _________.
A. it doesn’t need any detergent
B. it saves a large amount of water
C. it can remove all sorts of everyday stains
D. the plastic chips can be removed at the end of each wash
65. The writer supports his idea with __________ in Paragraph 4.
A. examples    B. words    C. data     D. imagination
66. What do we know about the Xeros from the passage?
A. It will be quite cheap as the plastic chips can be used up to 100 times.
B. It’ll take the place of the Dyson bagless vacuum cleaner in future.
C. The plastic chips play an important role in absorbing and removing the dirt.
D. It isn’t in the market now because no investors are willing to develop it.
67. What is the writer’s attitude toward the new technology in this passage?
A. Positive.        B. Opposed.       C. Indifferent.    D. Doubtful.

London’s Chinese community (社區(qū)) dates back to the 18th century, when a small number of Chinese sailors moved to the city to work in Limhouse, east London. As time went on, other Chinese people came to this area and Limhouse began to be known as “Chinatown”. However, London’s Chinese community remained very small for many years: at the start of the 20th century, there were just 545 Chinese people in Britain.
After the Second World War, many farmers in Hong Kong lost their jobs and came to London. As Limhouse had been almost destroyed during the war, they settled in a different area—a part of central London near Leicester Square. This area is now what Londoners call Chinatown.
At first, the new immigrants (移民) found it difficult to get jobs. In the 1950s, however, a small Chinese restaurant opened in London. Many British people visited it and said that Chinese food was wonderful! Suddenly, Chinese restaurants and take-aways started opening in every part of the city. Instead of too little work, the new Chinese immigrants now found that they had too much! They worked as cooks, managers or waiters. Most of them enjoyed their lives and arranged their friends and relatives to join them from overseas.
As time went by, London’s Chinese community became more and more successful. The sons and daughters of the original restaurant workers studied and worked very hard. And most went on to get highly paid jobs. Many Chinese families left Chinatown and moved to the more expensive outskirts. Chinatown, however, is still as lively as ever.
1. When did the first Chinese immigrants come to London?
_________________________________________________.
How many Chinese people were there in Britain at the beginning of the 20th century?

When we do not understand each other’s language, we can talk with the help of signs.
A Frenchman was once traveling in England. He could not speak English at all. One day, he went into a restaurant and sat down at a table. When the waiter came, he opened his mouth, put his fingers in it and take them out again. He wanted to say, “Bring me something to eat.”
The waiter soon brought him a cup of tea. The man moved his head from side to side. The waiter understood him and took the tea away. In a moment he came with a cup of coffee and put it on the table. The man again refused his offer. He shook his head whenever the waiter brought him something to drink, for drinks are not food.
When the man was going away, another man came in. This man saw the waiter, and he put his hands on his stomach. This was enough. In a few minutes there was a large plate of meat and vegetables on the table in front of him.
So you see, we can understand the language of signs as well as we can understand the language of words.

Beijing — Premier Wen Jiabao has urged the leadership of all countries to deepen their political will in tackling climate change woes (災(zāi)難) as uncertainties mount in the months before the United Nation’s conference in Cancun, Mexico, at the end of this year.
Wen made the remarks on Friday when he met with nearly 20 politicians, climate change and environmental ministers worldwide, who are in Beijing this weekend to attend an international forum on green economy and climate change.
Based on the achievements made at the Copenhagen Summit last December, Wen urged the rich countries to further clarify their compulsory carbon reduction targets. “At the same time, we developing countries should make clear our voluntary goal of slowing down climate change,” Wen said.
Wen also urged the developed countries to transfer climate change friendly technologies to the developing countries, especially the poorest countries and island nations.
During the meeting, Wen said China will redouble its efforts in reducing carbon emissions and improving energy efficiency during the coming years after it finishes its 2006-2010 goal of cutting energy consumption per unit of economic output by 20 percent.
While praising China for its green efforts, former Australian Prime Minister Robert J. Lee Hawke asked China to share its experiences and lessons on energy savings and pollution reduction to the rest of the world to tackle global environmental woes and climate change.
Wen responded: “China, together with the rest of the world, is willing to make its due contribution in coping with global warming and climate change.”
At a banquet for the foreign guests on Friday night, former vice-premier Zeng Peiyan said mounting uncertainties are ahead for the climate change negotiations. The world needs more dialogue and cooperation, Zeng said.
“Climate change woes are our shared challenges but the root lies in the historical emissions by the developed countries,” said Zeng, as president of the China Center for International Economic Exchanges, which organized the weekend climate change summit.
Zeng expected the forum to work as a platform for different countries to communicate their positions freely before the Bonn climate change negotiation in June and the Cancun conference at the end of this year.
51. Which title suits this passage best?
A. We must work on climate change.
B. We should share our ‘green’ technology.
C. We need to clarify our action targets.
D. We ought to cooperate to control the climate.
52. Why did Wen Jiabao urge the developed countries to clarify their carbon reduction targets?
A. Because the developed countries are not willing to deal with global environmental woes.
B. Because the developing countries have not set any goal of slowing down climate change.
C. Because there are mounting uncertainties ahead for the climate change negotiations.
D. Because agreements were already made at the Copenhagen Summit last December.
53. What kind of goal should a developing country have to slow down climate change?
A. A less important goal.                                          B. A self-assessed goal.
C. A negotiation-based goal                               D. A more compulsory goal.
54. The underlined part in the last paragraph but one implies ____________.
A. Air pollution just existed in the developed countries in the past.
B. In the past, the developed countries slowed down the development of the world.
C. Climate change woes were originally caused by the developed countries.
D. The rich countries should be more responsible since they polluted most.

There is an English saying, "  71  ". Until recently, few people took the saying seriously. Now, however, doctors have begun to look into laughter and the effects it had on human body.   72  .
Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their hearts, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercise.   73   it also works several groups of muscles in the face, the stomach, and even the feet. If laughter exercises the body, it must be beneficial.
Other tests have shown that laughter appears to be able to reduce the effect of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programs. The group that tolerated(忍耐) the pain for the longest time was the group which listened to a funny program.    74  
75   They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those caused by laughter.
A.Laughter can make one’s life longer.
B.As a result of these discoveries, some doctors in the United States now hold laughter clinics, in which they help to improve their patients’ condition by encouraging them to laugh.
C.The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemicals in the brain which diminish both stress and pain.
D.Laughter is the best medicine
E. They have found that laughter really can improve people's health
F. It increases blood pressure, the heart beating and breathing;
G. Although laughter can help cure the disease, doctors still can not put this theory into clinic practice.

“The first and best of victories is for a man to conquer himself; to be conquered by himself is, of all things, the most shameful,” says Plato. Self-control is at the root of all the advantages. Let a man give in to his impulses (沖動(dòng)) and feelings, and from that moment he gives up his moral (道德上的) freedom.
A single angry word has lost many a friend. When Socrates found in himself any temper or anger, he would check it by speaking low in order to control himself. If you are conscious of being angry, keep your mouth shut so that you can hold back rising anger. Many a person has dropped dead in great anger. Fits of anger bring fits of disease. “Whom the gods would destroy they first make mad.” “Keep cool”, says George Herbert, “for fierceness (狂怒) makes error a fault.”
To be angry with a weak man is to prove that you are not strong yourself. “Anger,” says Pythagoras, “brings with folly(愚蠢) and ends with regret.” You must measure the strength of a man by the power of the feelings he conquers, not by the power of those which conquer him.
Self-control is man’s last greatest victory.
If a man lacks self-control he seems to lack everything. Without it he can have no patience, no power to govern himself; he can have no self-confidence, for he will always be controlled by his strongest feeling. If he lacks self-control, the very backbone and nerve of character are lacking also.
64. What does the reader learn from the first paragraph?
A. The greatest victory for a man is to conquer everything except himself.
B. One’s moral freedom is based on the control of himself.
C. To control oneself is the most difficult in one’s life.
D. If a person is too stubborn, he will feel most shameful.
65. What is the correct interpretation of “Whom the gods would destroy they first make mad” ?
A. If the gods want to kill you, they make you crazy first.
B. If you always lose your temper, you will soon be finished.
C. If you cannot control yourself, you will become crazy.
D. If you are mad, you will be punished by the gods.
66. If a man lacks self-control, he lacks all of the following EXCEPT _______.
A. the very backbone and nerve of character 
B. the patience and power to control himself

Recently, the most popular topic among people in Zhongguancun has been: How far is Zhongguancun away from Silicon Valley (硅谷)? Can Zhongguancun be the next Silicon Valley?
People think that the day is not far when Zhongguancun will become a Silicon Valley. This is because Silicon Valley has two famous universities, Stanford and Berkeley universities, and Zhongguancun also has two universities, Peking and Tsinghua universities. Silicon Valley and Zhongguancun are gathering places for engineers. Silicon Valley has a group of well-known American high-tech companies including Intel and Hewlett-Packard, and Zhongguancun has famous companies such as Lenovo and Founder. Silicon Valley is good at science and technology, especially the information industry, while Zhongguancun is known as an electronics street.

This can bring about many problems and can easily lead to failure. Now the basic task for Zhongguancun is to know the demands of the market and the users.
Now, many overseas talents who are returning home are people who once studied, lived and worked in Silicon Valley. A group of first-class universities have taken part in the development of Zhongguancun. It’s believed that Zhongguancun can become the next Silicon Valley, but it doesn’t need to copy Silicon Valley in every way. Zhongguancun can become a Silicon Valley with Chinese characteristics.
