Wind is the great maker of waves. There are exceptions, such as the tidal waves, sometimes produces by earthquakes under the sea. But the waves most of us know are produced by winds blowing over the sea.Now before constructing an imaginary life history of a typical wave, we need to know certain physical things about it. A wave has height, from trough (low point)to crest (high point),and it has length—the distance from this crest to that of the following wave. The period of the wave means the time it takes for succeeding crests to pass a fixed point. None of these things stays the same— for all depend upon the depth of the water and many other matters.
The water that makes up a wave does not advance with it across the sea. Each drop of water turns around in a little circle with the passing of the wave, but returns very nearly to its original position. And it is fortunate that this is so, for if the huge masses of water that make up a wave actually moved across the sea, sailing would be impossible.
If we want to find the speed of a wave, we may use the following way:
Speeding="Wavelength×Frequency"
Here, wavelength is the distance between two high points (crests), frequency means the number of cycles per second.
41.What causes waves according to the passage?
A. Earthquakes and nothing else. B. Wind and volcanos.
C. Wind and earthquakes. D. Wind and water.
42.Which of the following is true according to the text?
A. The water of a wave moves away across the sea.
B. The water of a wave remains almost in the same place.
C. The water of a wave goes with the passing of the wave.
D. The length of a wave means the distance between crest and trough.
43.The underlined word “succeeding” means__________.
A. reaching an aim B. doing well C. following after D. taking place
44.If the speed of wave 1 is 100 cm/s, and its frequency 10;and the frequency of wave 2 is 300,while its speed is twice that of wave 1.Which of the following is true?
A. The wave-lengths of the two are equal.
B. The wave-length of wave 1 is 10 times longer than that of Wave 2.
C. The wave-length of wave 2 is longer than that of wave 1.
D. The wave-length of wave 1 is longer than that of wave 2.
Britain is facing a sharp rise in its rat population as growing numbers of people leave what they cannot finish of the fast food in the street, an environment group warned .Keep Britain Tidy said the rats were stopping their traditional hunts underground and were running across the streets, invited by burgers, pizzas and crisps left behind by man. “The rat population is on the rise and soon it’ll be as common to see a rat on our street as it is to see a dog or a cat,” said group Director, Sue Nelson. The practice of spreading fast food litter and scraps on the street rather than in the dustbin—with young men the worst group—was behind the rise. According to the National Rodent Survey in 2005, Britain’s rat population has grown by nearly one quarter since 2000 and is now estimated at 60 million, two million more than the human population. On average a rat can give birth every 24-28 days and just a single pair of rats can produce a family of 2,000 a year. Around 200 people a year get Weil’s Disease –an infection which can lead to liver or kidney（肝肾）failure and eventually death and which is carried in rats’ waste. To attract people’s attention to the problem, Keep Britain Tidy produced a cinema ad with a title “How close do you want them to get?” The ad gave a shocking image of a young woman sleeping in a bed of rats--reminding people of the terrible scene from James Herbert’s classic horror tale The Rats, in which rats begin to hunt for humans.Where did the rats use to search for food?
| A．In the street | B．Under the ground |
| C．From the dustbins | D．In burger shops |
What was the rat population in Britain in 2000 according to the writer?
| A．Around 60 million | B．Around 45 million |
| C．Around 38 million | D．Around 2 million |
We may infer from the passage that ______________.
| A．Weil’s Disease will finally end the world |
| B．pizzas and crisps will become unpopular |
| C．rats will put human beings’ life in danger |
| D．young people should take the responsibility for the rat population |
By writing the passage, the author tries to _____________.
| A．close some of the burger and pizza restaurants |
| B．draw the public attention to the problem of rats |
| C．prevent the rats from growing up |
| D．making an advertisement for the classic horror tale The Rats |
The creation of a Chinese Green Card in 2004 was a milestone in the country’s immigration law. Five years on, the card is an increasingly sought-after document.
On August 15, 2004, the Regulations on Examination and Approval of Permanent Residence
oAliens in China created a Green Card system granting qualified foreigners the right to live in
China permanently.
Liu Lili, who works in the Exit and Entry Administration of Beijing Municipal Public Security Bureau, has watched the Green Card system develop since its inception. She said nearly all applications received by the Bureau are approved. So far, 323 people have been granted a “Green Card” qualifying them for permanent residence in Beijing. Another 15 are awaiting final approval. It takes around 6 months to process each application.
Of the 323 Green Card holders, 94 are wives or husbands of Chinese citizens; 50 are minors dependent on their parents; 20 are senior citizens returning to live with relatives; 114 are individuals who have made outstanding contributions or are of special importance to China (another 7 are their family members); and 23 are high-level foreign personnel who hold posts in businesses (another 15 are their family members).
Liu said the authorities had been granting residence to returning senior citizens for some time before the Green Card system was formally launched .The government has approved permanent residence for over 3,000 foreigners since the implementation of the Law on Control of the Entry and Exit of Aliens which was adopted by the Standing Committee of the National People’s Congress in November 1985.
Four groups of people are eligible for permanent residence: high-level foreign personnel who hold posts in businesses that promote China’s economic, scientific and technological development or social progress; foreign citizens who make large direct investments in China; persons who have made outstanding contributions or are of special importance to China; and people who come to China to be with family, such as husbands and wives, minors dependent on their parents, and senior citizens dependent on their relatives.
Liu said that most applications she dealt with were from American citizens.
Why do overseas citizens apply for permanent residence status in China? The main concern, aid Liu, is the political factor. Once people have a “Green Card”, they feel they are accepted and trusted by the Chinese government. The “Green Card” also facilitates entry and exit. With permanent residence status, visas are no longer needed and people can enter and leave the country using only a valid passport. China offers outstanding career opportunities and is seen by many as safer and more secure than many other countries, said Liu.
Liu said that Green Card holders have the same rights and responsibilities as Chinese citizens. However the card is not equivalent to Chinese nationality and holders are not allowed to vote in elections, hold political office, or serve in the military.
Obtaining a Green Card is not easy. The qualifying conditions are tough. Unless you are a close relative of a Chinese citizen，you will either have to invest a substantial amount of money in the country or make a genuinely outstanding contribution to the country’s development.
To meet increasing demand, he authorities are considering making the Green Card more available by broadening the range of applicants without lowering the requirements, aid Liu, but she gave no further details.Which of the following can’t get a green card?
| A．A foreigner whose wife of husband is of Chinese nationality. |
| B．A foreign child whose parents are Chinese citizens. |
| C．A foreigner who invests large sum of money in China. |
| D．A foreigner who works in China for a long time. |
If a foreign gets a Green Card in China, he /she_________.
| A．has the right to vote in China. | B．can be a high official in China |
| C．can enter or leave China without a visa | D．becomes a citizen of Chinese nationality |
From the article we can see foreigners apply for Green Cards mainly to ________.
| A．show that they are important | B．be accepted and trusted by the Chinese |
| C．make entry and exit easier | D．make more money. |
Which of the following is not the reason for foreigners to work or live permanently in China?
| A．They can find satisfactory jobs. |
| B．China is more secure country than many. |
| C．They have their professions, families and investments in China. |
| D．The weather, working conditions are better than better than their own countries. |
People are talking about the “new economy.” It’s very different from the “old economy”.
In the old economy, people travel to walk. They buy things in stores. They use the post office, the fax and the telephone to send information. They see people face-to-face at their jobs or in stores. People get information from newspapers, radio, television, books and libraries.
In the new economy, people do business through the “net,” which is a connection of millions of computers everywhere in the world. In the new economy, workers often work at home. They can get information online. They can communicate with employers and co-workers by e-mail. Businesses have “virtual stores”. They are websites on which customers can see the products. Businesses can sell to customers anywhere in the world.
In the new economy, people live a fast paced, convenient and colorful life. The whole world develops more quickly than before. But the new economy is a double-edge sword. Its disadvantage is also obvious. For example, the Internet has led to a huge increase in credit card cheating. Some illegal websites offer some cheap or banned goods or services. Online shoppers who enter their credit card information may never receive the goods they want to buy and their card information could even be for sale in an illegal website. So people in the new economy should be smarter and knowledgeable.The cause of the differences between the new economy and the old economy is ____.
| A．the change of people’s idea | B．the business people do |
| C．the use of the Internet | D．the change of people’s life |
In the old economy, people can do the following things EXCEPT____.
| A．getting information from books |
| B．communicating with friends by telephone |
| C．meeting people face to face |
| D．shopping online |
“But the new economy is a double-edge sword ” in the last passage means_____.
| A．The new economy is as sharp as a sword |
| B．The new economy has advantages and disadvantages |

| B．Telephone, radio, television, newspapers and so on will disappear in the new economy. |
| C．People in the new economy should have high quality. |
| D．Life in the new economy is more comfortable than the one in the old economy. |
About ten years ago when I was an undergraduate in college in New York, I was working as a practice student at my University's Museum of Natural History. One day while I was working at the cash register in the gift shop, I saw an elderly couple come in with a little girl in wheelchair.
As I looked closer at this girl, I saw that she was seated on her chair. I then realized she had no arms or legs, just a head, neck and the trunk of the human body. She was wearing a little white dress with the patterns of red roses and yellow dots.
As the couple wheeled her up to me I was looking down at the register. I turned my head toward the girl and gave her a wink(眨眼示意). As I took the money from her grandparents, I looked back at the girl, who was giving me the most beautiful, largest smile I have ever seen
