One of the good things for men in women's liberation is that men no longer have to pay women the old-fashioned courtesies.
In an article on the new manners, Ms. Holmes says that a perfectly able woman no longer has to act helplessly in public as if she were a model. For example, she doesn't need help getting in and out of cars. "Women get in and out of cars twenty times a day with babies and dogs. Surely they can get out by themselves at night just as easily."
She also says there is no reason why a man should walk on the outside of a woman on the sidewalk. "Historically, the man walked on the inside so he caught the garbage thrown out of a window. Today a man is supposed to walk on the outside. A man should walk where he wants to. So should a woman. If, out of love and respect, he actually wants to take the blows, he should walk on the inside--- because that's where attackers are all hiding these days."
As far as manners are concerned, I suppose I have always been a supporter of women's liberation. Over the years, out of a sense of respect, I imagine, I have refused to trouble women with outdated courtesies.
It is usually easier to follow rules of social behaviour than to depend on one's own taste. But rules may be safely broken, of course, by those of us with the gift of natural grace. For example, when a man and woman are led to their table in a restaurant and the waiter pulls out a chair, the woman is expected to sit in the chair. That is according to Ms. Ann Clark. I have always done it the other way, according to my wife.
It came up only the other night. I followed the hostess to the table, and when she pulled the chair out I sat on it, quite naturally, since it happened to be the chair I wanted to sit in. I had the best view of the boats.
"Well," my wife said, when the hostess had gone, "you did it again."
"Did what？" I asked, utterly confused.
"Took the chair."
Actually, since I'd walked through the restaurant ahead of my wife, it would have been awkward, I should think, not to have taken the chair. I had got there first, after all.
Also, it has always been my custom to get in a car first, and let the woman get in by herself. This is a courtesy I insist on as the stronger sex, out of love and respect. In times like these, there might be attackers hidden about. It would be unsuitable to put a woman in a car and then shut the door on her, leaving her at the mercy of some bad fellow who might be hiding in the back seat.
It can be concluded from the passage that ______.
A．men should walk on the inside of a sidewalk
B．women are becoming more capable than before
C．in women's liberation men are also liberated
D．it's safe to break rules of social behaviour

Remember Second Life, the virtual world that was supposed to become almost as important as the first one？ Now populated by no more than 84,000 avatars at a time, it has turned out to be a prime example of how short-lived Internet fads can be. Yet if many adults seem to have given up on virtual worlds, those that cater to children and teenagers are thriving. Several have even found a way to make money.
In America, nearly 10 million children and teenagers visit virtual worlds regularly, estimates eMarketer, a market researcher-a number the firm expects to increase to 15 million by 2013．As in January, there were 112 virtual worlds designed for under-18s with another 81 in development, according to Engage Digital Media, a market research firm.
All cater to different age groups and tastes. In Club Penguin, the market leader, which was bought by Disney in 2007 for a whopping $ 700 million, primary-school children can take on a penguin persona, fit out their own igloo and play games. Habbo Hotel, a service run from Finland, is a global hangout for teenagers who want to customise their own rooms and meet in public places to attend events. Gala Online, based in Silicon Valley, offers similar activities, but is visited mostly by older teens who are into Manga comics.
Not a hit with advertisers, these online worlds earn most of their money from the sale of virtual goods, such as items to spruce up an avatar or a private room. They are paid for in a private currency, which members earn by participating in various activities, trading items or buying them with real dollars.
This sort of stealth tax seems to work. At Gala Online, users spend more than $1 million per month on virtual items, says Craig Sherman, the firm's chief executive. Running such a virtual economy is not easy, which is why Gaia has hired a full-time economist to grapple with problems that are well known in the real world, such as inflation and an unequal distribution of wealth.
There are other barriers that could limit the growth of virtual worlds for the young, but the main one is parents. Many do not want their offspring roaming virtual worlds, either because they are too commercial or are thought to be too dangerous. Keeping them safe is one of the biggest running costs, because their sponsors have to employ real people to police their realms.
Youngsters are also a fickle bunch, says Simon Levene of Accel Partners, a venture- capital firm. Just as children move from one toy to another, they readily switch worlds or social networks, often without saying goodbye.
Even so, Debra Aho Williamson, an analyst at eMarketer, believes "these worlds are a training ground for the three-dimensional web". If virtual worlds for adults, which so far have been able to retain only hardcore users, manage to hang on for a few years, they may yet have a second life.
In the first paragraph it says that "Several have even found a way to make money" Which of the following could possibly be the "way" ？
A．Sales of the copies of the game.
B．Sales of virtual goods in the game.
C．Sales of game peripheral goods, such as dolls and OST CDs.
D．Development of different games towards gamers of different ages.

Many science reports discuss medical studies that test the effect of a new drug. Usually, a large number of people is divided into two groups. Each group takes a different substance. But no one knows which group is getting which substance. One group takes the medicine being tested. Another group takes what we call an inactive substance. Medical researchers call this substance a "placebo." The word "placebo" is Latin for "I shall please." Placebo pills(宽心丸)usually are made of sugar.
Using placebos to test drugs sometimes has a surprising result. Researchers say people taking the placebo often report improvements in their health. This is known as "the placebo effect"--pain that is eased or stopped by an inactive substance. In such testing, the drug must perform. better than the placebo to prove that it is effective.
Doctors have reported that the placebo effect can be used in treatment. For example, a doctor tells a patient that a new drug will stop the pain in his leg. The pill is only sugar. But the patient does not know that. He takes the pill and says his pain is gone.
Scientists are beginning to discover some physical reasons for this reaction in some people. They are learning that much of what people believe to be true comes from what the brain expects is going to happen. If the brain believes a drug will ease pain, the brain may begin physical changes in the body that can cause the expected effect. A recent examination of studies on drugs for depression found that placebos eased the depression about as well as the active drugs.
Other studies have explored the power of placebos. A study in Japan involved thirteen
people who reacted to the poison ivy (常青藤)plant. Poison-ivy causes red itchy sores(伤痕)on some people who touch it. Each person was rubbed on one arm with a harmless leaf, but was told it was poison ivy. Each person was then touched on the other arm with poison ivy, but was told it was a harmless leaf. All thirteen people developed a reaction on the arm where the harmless leaf touched their skin. Only two reacted to the poison ivy leaves.
Doctors and scientists worry that the use of placebos may not always be harmless. They say people can become victims of false doctors and others who use placebos to claim they can cure disease.
What do medical researchers usually use to make placebo pills？
A．Ivy leaves.
B．Harmless leaves.
C．Medicine being tested.
D．sugar.

No reference book, perhaps no book of any kind except the Bible, is so widely used as "the dictionary". Even houses that have few books or none at all possess at least one dictionary; most business offices have dictionaries, and most typists keep a copy on their desks; at one time or another most girls and boys are required by their teachers to obtain and use a dictionary.
Admittedly, the dictionary is often used merely to determine the correct spelling of words, or to find out the accepted pronunciation, and such a use is perhaps not the most important from an intellectual point of view. Dictionaries may, however, have social importance, for it is often a matter of some concern to the person using the dictionary for such purpose that he should not suggest to others, by misspelling a word in a letter, or mispronouncing it in conversation, that he is not "well-bred", and has not been well educated.
Yet, despite this familiarity with the dictionary, the average person is likely to have many wrong ideas about it, and little idea of how to use it profitably, or interpret it rightly. For example, it is often believed that the mere presence of a word in a dictionary is evidence that it is acceptable in good writing. Though most dictionaries have a system of marking words as obsolete, or in use only as slang, many people, more especially if their use of a particular word has been challenged, are likely to conclude, if they find it in a dictionary, that it is accepted as being used by writers of established reputation. This would certainly have been true of dictionaries a hundred years or so ago. For a long time after they were first firmly established in the eighteenth century, their aim was to include only what was used by the best writers, and all else was suppressed, and the compiler frequently claimed that this dictionary contained "low" words. Apparently this aspect of the dictionary achieved such importance in the mind of the average person that most people today are unaware of the great change that has taken place in the compilation of present-day dictionaries.
Similarly, the ordinary man invariably supposes that one dictionary is as good and authoritative as another, and, moreover, believes that "the dictionary" has absolute authority, and quotes it to clinch arguments. Although this is an advantage, in that the dictionary presents a definition the basic meaning of which can't be altered by the speaker, yet it could be accepted only if all dictionaries agreed on the particular point in question. But ultimately the authority of the dictionary rests only on the authority of the man who compiled it, and, however careful he may be, a dictionary-maker is fallible: reputable dictionaries may disagree in their judgments, and indeed different sections of the same dictionary may differ.
Which of the following statements is TRUE according to the passage？
A．The Bible is the most widely used reference book.
B．The dictionary is the most widely used reference book.
C．The dictionary is actually the more widely used book than the Bible.
D．The Bible is used as widely as the dictionary.

Is it possible that the ideas we have today about ownership and property rights have been so universal in the human mind that it is truly as if they had sprung from the mind of God？ By no means. The idea of owning and property emerged in the mists of unrecorded history. The ancient Jews, for one, had a very different outlook on property and ownership, viewing it as something much more temporary and' tentative than we do.
The ideas we have in America about the private ownership of productive property as a natural and universal right of mankind, perhaps of divine origin, are by no means universal and must be viewed as an invention of man rather than an order of God. Of course, we are completely trained to accept the idea of ownership of the earth and its products, raw and transformed. It seems not at all strange; in fact, it is quite difficult to imagine a society without such arrangements. If someone, some individuals, didn't own that plot of land, that house, that factory, that machine, that tower of wheat, how would we function？ What would the rules be？ Whom would we buy from and how would we sell？
It is important to acknowledge a significant difference between achieving ownership simply by taking or claiming property and owning what we tend to call the "fruit of labor." If I, alone or together with my family, work on the land and raise crops, or if I make something useful out of natural material, it seems reasonable and fair to claim that the crops or the objects belong to me or my family, are my property, at least in the sense that I have first claim on them. Hardly anyone would dispute that. In fact, some of the early radical workingmen's movements made (an ownership) claim on those very grounds. As industrial organization became more complex, however, such issues became vastly more intricate. It must be clear that in modem society the social heritage of knowledge and technology and the social organization of manufacture and exchange account for far more of the productivity of industry and the value of what is produced than can be accounted for by the labor of any number of individuals. Hardly any person can now point and say, "That--that right there--is the fruit of my labor." We can say, as a society, as a nation--as a world, really--that what is produced is the fruit of our labor, the product of the whole society as a collectivity.
We have to recognize that the right of private individual ownership of property is man-made and constantly dependent on the extent to which those without property believe that the owner can make his claim, dependent on the extent to which those without stick.
According to the passage, the concept of ownership probably ______.
A．resulted from the concept of property right
B．stemmed from the uncovered prehistoric ages
C．arose from the generous blessing of the Creator
D．originated from the undetected Middle Ages

Imagine that the world consists of 20 men and 20 women, all of them heterosexual and in search of a mate．Since the numbers are even, everyone can find a partner．But what happens if you take away one man？ You might not think this would make much difference．You would be wrong，argues Tim Harford，a British economist， in a book called The Logic of Life． With 20 women pursuing 19 men, one woman faces the prospect of spinsterhood． So she ups her game． Perhaps she dresses more seductively． Perhaps she makes an extra effort to be obliging． Somehow or other, she “steals” a man from one of her fellow women． That newly single woman then ups her game, too, to steal a man from someone else． A chain reaction ensues．
Real life is more complicated, of course, but this simple model illustrates an important truth．In the marriage market, numbers matter．And among African-Americans，the difference is much worse than in Mr．Harford's imaginary example．Between the ages of 20 and 29, one black man in nine is behind bars．For black women of the same age, the figure is about one in 150．For obvious reasons, convicts are excluded from the dating pool．
Removing so many men from the marriage market has profound consequences．As imprisonment rates exploded between 1970 and 2007， the proportion of U.S.-born black women aged 30-44 who were married plunged from 62%to 33%．Why this happened is complex and furiously debated．The era of mass imprisonment began as traditional mores were already crumbling， following the sexual revolution of the 1960s and the invention of the contraceptive pill．① It also coincided with greater opportunities for women in the workplace． These factors must surely have had something to do with the decline of marriage．
But jail is a big part of the problem, argue Kerwin Kofi Charles, now at the University of Chicago． They divided America up into geographical and racial “marriage markets”, to take account of the fact that most people marry someone of the same race who lives relatively close to them．② Then, after crunching the census numbers， they found that a one percentage point increase in the male imprisonment rate was associated with a 2.4-point reduction in the proportion of women, who ever marry．③ Could it be, however, that mass imprisonment is a symptom of increasing social malfunction, and that it was this social malfunction that caused marriage to wither？④ Probably not. For similar crimes, America imposes much harsher penalties than other rich countries．Mr. Charles and Mr. Luoh controlled for crime rates, as a substitution for social malfunction, and found that it made no difference to their results. They concluded that “higher male imprisonment has lowered the likelihood that women marry...and caused a shift in the gains from marriage away from women and towards men.”

One of the best-known proverbs must be "early to bed, early to rise, makes a man healthy, wealthy, and wise." The promises of health, wealth, and wisdom to those who join the ranks of the early retires and risers must be particularly appealing to many people in our contemporary society. There is no doubt that one of the greatest concerns of modern man is his health. It is estimated that in the United States $ 200 billion are spent on health care each year. The medical field has grown into such a big business that it employs 4.8 million people, and it appears that in many places, more staff is needed to meet the demands of the people who are concerned about their physical well-being.
Much more interest has been shown in preventive medicine in recent years. This is probably due in part to the increasing costs of medical treatment, but the writings of such people as Dr. Keneth Cooper have also played an important role. In his book Aerobics. Dr. Cooper communicated his message of the benefits of exercise so effectively that many other authors have flowed in his trail, and literally millions of readers have put on their sports shoes and taken to the highways and byways of America. A recent survey showed that over 17 million people are jogging. Many of these are so serious that they have trained themselves to run the 26 miles and 385 yards of the hard and tiring marathons that are sponsored all over the country. The last time I was in Honolulu, I was amazed to see hundreds of people, young and old, running for their lives, and I discovered many of them have run in the Hawaiian Marathon.
Exercise has also become a major part of conversation. A1 a dinner party recently, the president of a bank asked me, "You look like a runner; how far do you run each day？" A few days later when I appeared on a national television show, the host suddenly asked me if I was a regular runner. On both occasions the conversation turned to the subject of exercise and I found, as I have found whenever I have traveled recently, that this is a subject on many people's minds. Of course, there are still many people who are less than enthusiastic about exercise. They appreciate the philosophy of Robert M. Hutchins who said, "Whenever the thought of exercise occurs to me, I lie down till it passes."
The first paragraph indicated that medical workers ______.
A．are in great demand？
B．make a lot of money
C．are concerned with their own health
D．like sports more than ordinary people
