Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.
People nowadays have a wide choice of leisure time activities. Some people enjoy quiet leisure time activities after a long hard day at work or school. Watching TV is certainly the most popular leisure time activity in Britain. The average person watches a few hours of it every day. The most popular programmes are soap operas, which follow the(often extraordinary) activities of fictitious people, and news programmes. Most British people watch the TV news at some point in the evening, perhaps whilst eating dinner or just before going to bed.
British people often find entertainment in collecting things. There are people in Britain who collect any kind of object you care to name. By far the most common thing to collect is stamps. Most people are happy to collect whatever stamps come their way, but others collect thematically, i.e. they collect certain kinds of stamps, e.g. stamps with pictures of animals on them or stamps that come from a certain country. I know people who collect matchboxes, dolls, and even the free gifts from fast food restaurants. Some people take collecting not so much as a hobby, but as an investment, which is reasonable since many collections are worth a lot of money.
Although many people prefer to watch sport on TV, playing sport has always been popular in Britain. You must have heard of some of the big British football clubs. Of course, few people get to play sport at a high level, but British people are often happy to play a sport "just for fun". Popular sports that British people enjoy playing include football, rugby, cricket, golf, tennis, badminton, and squash. Many people play sport to keep fit, but most British people do it "for the love of the game".
Another form. of entertainment in Britain is simply going out and socializing with friends. Contrary to popular belief, British people are very friendly and are usually quite happy to start up a conversation with a stranger. Socialising often involves going to a pub with friends, but there are many other alternatives. Cafes are becoming increasingly popular and British people also like to join clubs so that they can meet people who have similar interests. If you have an interest, you'll be sure to find a British person who shares it!
The large majority of British people tend to ______.
Gender Pay Gap, Once Narrowing, Is Stuck in Place
Throughout the 1980s and early '90s, women of all economic levels—poor, middle class and rich—were steadily gaining ground on their male counterparts in the work force. By the mid-'90s, women earned more than 75 cents for every dollar in hourly pay that men did, up from 65 cents just 15 years earlier.
Largely without notice, however, one big group of women has stopped making progress: those with a four-year college degree. The gap between their pay and the pay of male college graduates has actually widened slightly since the mid-'90s.
For women without a college education, the pay gap with men has narrowed only slightly over the same span.
These trends suggest that all the recent high-profile achievements—the first female secretary of state, the first female lead anchor of a nightly newscast, the first female president of Princeton, and, next month, the first female speaker of the House—do not reflect what is happening to most women, researchers say.
A decade ago, it was possible to imagine that men and women with similar qualifications might one day soon be making nearly identical salaries. Today, that is far harder to envision.
"Nothing happened to the pay gap from the mid-1950s to the late '70s," said Francine D. Blau, an economist at Cornell and a leading researcher of gender and pay. "Then the '80s stood out as a period of sharp increases in women's pay. And it's much less impressive after that."
Last year, college-educated women between 36 and 45 years old, for example, earned 74.7 cents in hourly pay for every dollar that men in the same group did, according to Labor Department data analyzed by the Economic Policy Institute. A decade earlier, the women earned 75.7 cents.
The reasons for the stagnation are complicated and appear to include both discrimination and women's own choices. The number of women staying home with young children has risen recently, according to the Labor Department; the increase has been sharpest among highly educated mothers, who might otherwise be earning high salaries. The pace at which women are flowing into highly paid fields also appears to have slowed.
Like so much about gender and the workplace, there are at least two ways to view these trends. One is that women, faced with most of the burden for taking care of families, are forced to choose jobs that pay less—or, in the case of stay-at-home mothers, nothing at all.
If the government offered day-care programs similar to those in other countries or men spent more time caring for family members, women would have greater opportunity to pursue whatever job they wanted, according to this view.
The other view is that women consider money a top priority less often than men do. Many may relish the chance to care for children or parents and prefer jobs, like those in the nonprofit sector, that offer more opportunity to influence other people's lives.
Both views, economists note, could have some truth to them.
"Is equality of income what we really want？" asked Claudia Goldin, an economist at Harvard who has written about the revolution in women's work over the last generation. "Do we want everyone to have an equal chance to work 80 hours in their prime reproductive years？ Yes, but we don't expect them to take that chance equally often."
Whatever role their own preferences may play in the pay gap, many women say they continue to battle subtle forms of lingering prejudice. Indeed, the pay gap between men and women who have similar qualifications and work in the same occupation—which economists say is one of the purest measures of gender equality—has barely budged since 1990. Today, the discrimination often comes from bosses who believe they treat everyone equally, women say, but it can still crea
