As a result of pollution , Lake Erie , on the borders of the USA and Canada, is now without any living things.  
Pollution in water is not simply a matter of “poisons” killing large numbers of fish overnight. Very often the effects of pollution are not noticed for many months or years because the first organism(生物体 ) to be affected are either plants or plankton. But these organisms are the food of fish and birds and other creatures. When this food disappears, the fish and birds die too. In this way a whole food chain can be wiped out, and it is not until dead fish and water birds are seen at the river’s edge or on the sea shore that people realize what is happening.  
Where do the substances which pollute the water come form? There are two main sources sewage (污水) and industrial waste. As more detergent (洗涤剂 ) is used in the home, so more of it is finally put into our rivers. lakes and seas. Detergents harm water birds dissolving the natural substances which keep their feathers waterproof. Sewage itself, if not properly treated, makes the water dirty and prevents all forms of life in rivers and the sea from receiving the oxygen they need. Industrial waste is even more harmful since there are many highly poisonous things in it, such as copper and lead(铅 ).  
So , if we want or stop this pollution , the answer is simple: sewage and industrial waste must be made clean before flowing into the water. It may already be too late to save some rivers and lakes, but others can still be saved if the correct action is taken at once.  
72. Pollution in water is noticed _____.   
A. when the first organisms are affected    B. when a good many fish and birds die   
C. when poisonous things are poured into water        
D. as soon as the balance of nature is destroyed   
73. The living things die because there is no ____ in the lake or river.    
A. water          B. fish               C. poison           D. oxygen   
74. Which of the following is harmful according to the passage?   
A. Organisms                             B. Plants and plankton in the water       
C. Waste water from cleaning   D. Industrial waste made clear before flowing into the water   
75.The way to stop water pollution is _______.  
A. realize the serious situation clearly   
B. put oxygen into the river   
C. make the waste material harmless before flowing into the water   
D. make special room in the sea for our rubbish

Restaurants in Europe, the United States and Japan are testing technology to let diners order their food direct from a screen at their table instead of depending on a fellow human being to note their choice.
Besides cutting costs, companies that sell the “e-menus” argue the bytes-for-bites way has a new value that can attract younger customers, and various photographs of steaks and gooey desserts attract diners to order more. It also could extend the TV dinner. How about a computer game dinner?
“It's about impulse-buying,” said Adi Chitayat, Conceptic’s CEO. “If a person starts looking at pictures of chocolate cake, the chances are he'll order it.” Frame, a restaurant in Tel Aviv with the system, is said to have its sales on tables with the e-menu increased by about 11% . Customers often call ahead to reserve (预定)spots equipped with screens, manager Natalie Edry told Reporters.
At one of the e-menu tables, IT worker Gil Uriel and his young family were enthusiastic as they checked out pictures of the dishes on offer and squabbled(争吵)overdesserts. “It’s more visual,” says Uriel, as his children clicked away furiously on a games function between courses. “We can still choose, we can still argue —but it’s much easier when we can all see it.”
The following are the advantages of “restaurants with” EXCEPT that .

A.eating in them is more comfortable
B.the restaurants can save a lot of money
C.they can attract more youngsters to the restaurants
D.customers can see the pictures of their ordered foods

The underlined word “impulse—buying” in the 3rd paragraph means.

A.having no idea in buying things
B.being uninterested in buying things
C.having no patience in buying things
D.being encouraged in buying things

According to the last paragraph, we know that.

A.customers feel little interest in the e-menus
B.e-menus only attract a small number of customers
C.it still takes time for e-menus to be widely accepted
D.restaurants of this kind are refused by customers

This passage might be taken from .

A.a food guide B.a website
C.a traveling magazine D.classic advertisements

Prison Break is a huge hit thanks to its handsome star, Wentworth Miller. His character, Michael Scofield, is the engine that drives the show.
Having committed a crime to get into prison and break out with his innocent brother, Michael Scofield is one of the most interesting personalities on TV today. But what about the man behind the character?
Miller,35, is a hard guy to figure out. He does not come from a normal background and has never lived his life in a typical way.
Miller didn’t take direct path to fame and fortune. He graduated from Princeton University in 1995, not with a degree in theatre of film, but in English. He didn’t even act when he was in college. His only performance experience was in his university’s singing group. Yet , at graduation Miller still decided to make the move to Hollywood.
Miller has always been different. Although he is American, he was in Britain when his father was studying there. His family background is also a special mix of cultures. “My father is black and my mother is white. That means I have always been caught in the middle. I could be either one, which can make you feel out of place,” Miller says.
Following his unusual path, Miller did not start trying out for films and TV shows when he
first went to Hollywood. Instead, he worked as a lowly production assistant. Not what you would expect from a Princeton graduate. However, it all paid off for Miller in the end.
In 2002, Miller played a role in the drama Dinotopia(《恐龙帝国》). He starred as a thoughtful and shy man. Producers remembered his performance when they were casting Prison Break two years later. With a golden globe nomination(提名)and another season of Prison Break on his resume, Miller seems ready to take over all of Hollywood.
What does the passage mainly talk about?

A.Michael Scofield in Prison Break .
B.Hollywood’s recent big hit—Prison Break.
C.Miller’s unusual path to fame and fortune.
D.The man who will take over all of the world.

The writer thinks “Miller is a hard guy to figure out” because.

A.it’s difficult to tell him from others
B.he is a shy man and hard to cooperate with
C.he always has ideas hard for people to understand
D.his family background and life experience are very special

Which is the closest in meaning to the underlined sentence “it all paid off for Miller in the end”?

A.Miller put a lot of extra work for his final success.
B.Miller gained fame and fortune at last with his first film.
C.Miller finally succeeded even if he has been in low position.
D.Miller managed to pay off his debts with his small income in the end.

Which of the following statements is TRUE about Miller?

A.He is chosen to play the Michael Scofield due to his interesting personality.
B.His performance in Dinotopia makes some contributions to his success.
C.He has the same experience with the character Michael Scofield.
D.He is angry about his being born into a mixed-cultural family.

There’s been a lot of talk about white-and-blue collar workers, and you may have even heard of gold collar workers, but lately a new color of collar is making its way into China’s urban vernacular(土话)—green. Green collars say no when work is life and life is work. They choose to get out of the fast lane(车道), and explore new ways of living “green”.
Living green doesn’t mean someone is working as an environmentalist, biologist or scientist. Instead it is more of a lifestyle choice. A typical green collar is well educated like a white-collar but physically tough like a blue-collar, likely born in the 70s or 80s of the last century and living in one of China’s big cities, with a monthly income well above 5,000 yuan (about US $700).
The life of a green collar may go something like this; Turn off the mobile phone after work, eat only healthy food rich in vitamins, go on hikes every weekend, and like to help the underprivileged.
Green collars even have their own club. In Beijing, the Green Collar Club is for people who share a “be happy, healthy and helpful” spirit. The club often holds charity parties and uses the donations for environmental protection and poverty relief(摆脱贫困)projects in China.
“They are successful in their careers, but do not miss the pleasures in life. They have a lot of money, but do not fall slave to it.” said Zuo Shiguang, one of the founding members of the club.
What is the passage mainly about?

A.Differences between white-and-blue collars and green collars.
B.The increasing awareness of environmental protection.
C.New trends of life in China’s big cities.
D.The lifestyle of green collars.

Green collars willafter work.

Dear Sirs,
Your shipment(装运)of twelve thousand“Smart”watches was received by our company this morning.However,we wish to make a number of complaints concerning the serious delay in delivery and your failure to carry out our instructions.
It was stressed from the beginning that the delivery date had to be less than six weeks. While we appreciate that delays in production are occasionally unavoidable.We must point out that the major reason why the order was placed with your company was that we were assured by you that your existing stocks ensure immediate shipment.Late delivery of the goods has caused us to disappoint several of our most valued customers.and is sure to have a negative effect on future orders.
The second complaint concerns the difference in colour.Only half the watches in the delivery received are of the colours we ordered.Our Hong Kong agent assures us that she stressed to you the importance of following our instructions.Since we consider there to be only a limited market in this country for watches of other colours.Any watches that are not of the specified colours will , of course, be returned to you.
We are also somewhat concerned about the rather poor quality of the goods received.since it is obvious that the watches that finally arrived have been produced from inferior materials and have been made to a lower standard than those in the sample.We have also found that a number of the watches do not appear to be functioning.We should like to point out that we feel this matter to be entirely your responsibility.
As a result of the above problems,therefore,we feel that the most suitable course of action is to return to you unpaid any of the goods considered unsatisfactory,and to deduct(扣除)any costs from our final settlement.We shall also be forced to reconsider whether any further orders should be placed with your company.
We look forward to your immediate reply.
Yours sincerely,
John Smith

LONDON (AP) — England joins on Sunday the growing list of places that ban smoking in public buildings, taxis and other places including even Buckingham Palace with a tough law.
Pubs, clubs and restaurants will all be smoke-free. Taxi and delivery drivers have been warned that they too could be fined 50 pounds, or about $100, if caught lighting up inside work vehicles.
Experts say the bans have become an irreversible (不可逆转的) tread because of greatly rising health costs and public uneasiness over second-hand smoke. Some of the strictest smoking bans are in the United States, even though there is no federal anti-smoking policy. New York and Florida have strict bans, while California has certain outdoor smoking bans.
Spain, Italy, Iran, Norway, Sweden, Singapore, South Africa, Uruguay and new Zealand have passed legislation(立法) to restrict smoking. France banned smoking in many public places in February and plans to extend the ban to cafes and restaurants next year. Finland is introducing a ban in 2009.
Despite the spread of bans, the World Health Organization predicts a steady rise in tobacco sales. In its Tobacco Atlas, the WHO said that by 2030 there will be “at least another two billion smokers in the world” and an expected decrease in male smokers “will be offset by an increase in female smoking rates, especially in developing countries.”
In advance of the English ban, anti-smoking ads have coated bus stops and the British government has subsidized(资助) programs to help people quit. The rest of Britain—Scotland, Wales and Northern Ireland —already have smoking bans in place.
The first two paragraphs mainly tell us_______

A.Buckingham Palace bans smoking
B.smoking ban comes into force in England
C.there’s no smoking in Buckingham Palace
D.smoking is against the law in England

Which of the following places may still be smoking areas in England?

A.Private houses B.Taxis.
C.Restaurants. D.London clubs

B.There is an extremely strict smoking ban everywhere in America.
C.Smoking situation is still serious across the world.
D.Related ads didn’t appear in England until the English ban was lifted.(解除)
