Pop stars today enjoy what once only belonged to the royalty(皇室)．Wherever they go，people turn out in their thousands to greet them.The crowds go wild trying to catch a brief glimpse of their smiling，colorfully dressed idols.The stars are transported in their chauffeur driven Rolls Royces，private helicopters or executive aeroplanes.They are surrounded by a permanent entourage(隨從)of managers，press agents and bodyguards.Photographs of them appear regularly in the press and all their comings and goings are reported，for，like royalty，pop stars are news.If they enjoy many of the privileges of royalty，they certainly share many of the inconveniences as well.It is dangerous for them to make unscheduled appearances in public.They must be constantly shielded from the adoring crowds who idolize them.They are no longer private individuals，but public property.The financial rewards they receive for this sacrifice cannot be calculated，for their rates of pay are great.

And why not？Society has always rewarded its top entertainers lavishly.The great days of Hollywood have become legendary：famous stars enjoyed fame，wealth and adulation(奉承)on an all time scale.By today's standards，the excesses of Hollywood do not seem quite so spectacular.A single gramopphone record nowadays may earn much more in royalties than the films of the past ever did.The competition for the title“Top of the Pops”is fierce，but the rewards are truly huge.

It is only right that the stars should be paid in this way.Don't the top men in industry earn enormous salaries for the service they perform to their companies and their countries？Pop stars earn vast sums in foreign currency—often more than large industrial companies—and the taxman can only be grateful for their massive annual contributions to the exchequer(國庫)．So who would begrudge them their rewards?

It's all very well for people in boring jobs to complain about the successes and rewards of others.People who make envious remarks should remember that the most famous stars represent only the tip of the iceberg.For every famous star，there are hundreds of others struggling to earn a living.A man working in a steady job and looking forward to a pension at the end of it has no right to expect very high rewards.He has chosen security and peace of mind，so there will always be a limit to what he can earn.But a map who attempts to become a star is taking enormous risks.He knows at the outset that only a handful of competitors ever get to the very top.He knows that years of concentrated effort may be rewarded with complete failure.But he knows，too，that the rewards for success are very high indeed：they are the payback for the huge risks involved and once he makes it，he will certainly earn them.That's the essence of private enterprise.

1.The author develops the passage mainly by ________.

A．comparing different ideas

B．giving explanations

C．inferring

D．listing typical examples

2.The underlined word “begrudge” in the third pararaph is closest in meaning to ________.

A．be jealous of? ????????????? B．be satisfied with

C．be anxious about? ????????????? D．be crazy about

3.According to the passage，which of the following can match the view of the author?

A．He who laughs last laughs best.

B．If you venture nothing，you will gain nothing.

C．He who makes no mistakes makes nothing.

D．Success belongs to the persevering.

4.Which of the following is true according to the passage?

A．People are blind in idolizing stars.

B．There is fierce competition in becoming pop stars.

C．The government taxes pop stars very little.

D．Pop stars' life is more luxurious than that of royalty.

Thirty years ago, the Earnshaw family lived at Wuthering Heights, with two teenaged children Hindley and Catherine. Mr. Earnshaw travels to Liverpool, where he adopts a homeless Gypsy boy, naming him "Heathcliff". Hindley finds himself robbed of his father's love and care and becomes bitterly jealous of the newcomer. However, Catherine grows very attached to him. Soon, the two children spend hours on the moors (荒原) together and hate every moment apart.

Because of the conflict(沖突), Hindley is eventually sent to college. However, he marries a woman named Frances and returns three years later, after Mr. Earnshaw dies. He becomes master of Wuthering Heights, making Heathcliff their servant instead of a family member.

Months after Hindley’s return, Heathcliff and Catherine travel to Thrushcross Grange to spy on the Linton family. However, they are found and try to escape. Catherine is caught by a dog, and then brought inside the Grange to have injuries tended to while Heathcliff is sent home. Catherine eventually returns to Wuthering Heights as a changed woman, looking and acting as a lady. She laughs at HeathcIiff’s dirty appearance. When the Lintons visit the next day, Heathcliff dresses up to impress her. It fails, however, when Edgar, one of the Lintons' children, argues with him. Heathcliff is locked in the attic, where Catherine later tries to comfort him. He swears revenge(報(bào)復(fù)) on Hindley.

In the summer of the next year, Frances gives birth to a son, Hareton, but she dies before the year is out. This leads Hindley to fall into a life of drunkenness and waste. Two years pass and Catherine has become close friends with Edgar, growing more distant from Heathcliff.

One day in August, while Hindley is absent, Edgar comes to visit Catherine. Before long, they declare themselves lovers. Catherine explains to Nelly, her servant, that she does not really love Edgar but Heathcliff. Unfortunately, she could never marry Heathcliff because of his lack of status and education. She therefore plans to marry Edgar and use that position to help raise Heathcliff’s status. Unfortunately, Heathcliff has overheard the first part and runs away, disappearing without a trace. After three years, Edgar and Catherine are married.

Six months after their marriage, Heathcliff returns as a gentleman, having grown stronger and richer. Catherine is delighted to see him although Edgar is not so keen. Edgar's sister, Isabella, now eighteen, falls in love with Heathcliff. He looks down upon her but encourages the adolescent love, seeing it as a chance for revenge on Edgar. When he embraces Isabella one day at the Grange, there is an argument with Edgar, which causes Catherine to lock herself in her room and fall ill.

Heathcliff has been staying at the Heights, gambling with Hindley and teaching Hareton bad habits. Hindley is gradually losing his wealth, mortgaging （抵押) the farmhouse to Heathcliff to repay his debts.

While Catherine is ill, Heathcliff leaves with Isabella, causing Edgar to disown （與……斷絕關(guān)系) his sister. The two marry and return two months later to Wuthering Heights. Heathcliff hears that Catherine is ill and arranges to visit her in secret. In the early hours of the day after their meeting, Catherine gives birth to her daughter, Cathy, and then dies. Hindley dies six months after Catherine. Heathcliff finds himself the master of Wuthering Heights and the guardian of Hareton.

1.From the first paragraph, we can know ______ .

A．Hindley hates the fact that his parents give all their love and care to Catherine

B．Mrs. Earnshaw adopts Heathcliff in Liverpool

C．Hindley is the oldest of all three children

D．Catherine likes Heathcliff so much that she enjoys staying with him for long

A．lives a disordered life                    B．locks Heathcliff in the attic

C．a(chǎn)rgues with Heathcliff very often            D．returns to Wuthering Heights as a changed man .

3.The underlined part "the first part" in Paragraph 5 most probably refers to ________ .

A．Catherine says that Edgar has asked her to marry him and she has agreed

B．Catherine loves Heathcliff but can't marry him because of his lack of status and education

C．Catherine decides to marry Edgar, with whose help she can help raise Heathcliff’s status

4.At the end of the story________.

科目：高中英語 來源：黑龍江省2010屆高三下學(xué)期第四次模擬考試試題（英語） 題型：七選五

 

第二節(jié) （共5小題；每小題2分，滿分10分）

根據(jù)短文內(nèi)容，從短文后的選項(xiàng)中選出能填入空白處的最佳選項(xiàng)。選項(xiàng)中有兩項(xiàng)為多余選項(xiàng)。

Everyone knows that the Frenchmen are romantic, the Italians are fashionable and the Germans are serious. Are these just stereotypes or is there really such a thing as national character? And if there is, can it affect how a nation succeed or fail?

At least one group of people is certain that it can. A recent survey of the top 500 entrepreneurs (企業(yè)家) in the UK found that 70% felt that their efforts were not appreciated by the British public. Britain is hostile (敵意的) to success, they said. It has a culture of jealousy(嫉妒).   71  Jealousy is sometimes known as the “green – eyed monster” and the UK is its home.

Scientists at Warwich University in the UK recently tested this idea. They gathered a group of people together and gave each an imaginary amount of money.   72    Those given a little were given the chance to destroy the large amount of money given to others – but at the cost of losing their own. Two thirds of the people tested agreed to do this.

  73    But there is also opposite evidence. The Organization for Economic Cooperation and Development recently reported that the UK is 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 is 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 proud or unfair or which separates them from their roots.”

  74    They set out to do things in their way. They work long hours. By their own efforts they become millionaires.   75   It hardly seems worth following their example. If they were more friendly, people would like them more. And more people want to be like them.

A. This seems to prove that the entrepreneurs were right to complain.

B. The one who owns most money in the end is the winner.

C. As a result, the survey said, entrepreneurs were “unloved, unwanted and misunderstood.”

D. It is not true that British people are born jealous of others` success.

E. Some were given a little, others a great deal.

F. But instead of being happy they complain that nobody loves them.

G.. Perhaps it is the entrepreneurs who are the problem.
