One reason for the stabilizations of divorce is the reduction in the risk factors—fewer teenagers marrying, fewer early births in marriage, fewer pre-marital(婚前的) conceptions.
Another reason which was aired at the annual conference of the British Society for Population Studies, was the increase in cohabitation. Some speakers argued that the increase in cohabitation has meant that marital couples are now much more familiar with each other before marriage and therefore less likely to separate.
One out of four couples who marry today have lived together and in the older age groups the proportion is much higher. Some 34 percent of women aged over 25 who marry have cohabited, and over 50 percent of women who are marrying a divorced man or who have been divorced themselves, cohabit before marriage.
Cohabitation in Britain, however, is still considerably lower than in many European states and was described by the demographers as "essentially a part of contemporary courtship". Only a small proportion of people who cohabited had children whereas in Sweden some 40 percent of births were now outside formal marriage. The British rate was 13 percent.
Kath Kiernan of the Centre for Population Studies noted that the present statistics suggested that there was a marginally higher risk of separation for couples who had cohabited, but this could possibly be explained by the fact that the statistics covered a period when cohabiting had not become as socially acceptable as it was today.
A third reason why the demographers thought the divorce rate could stabilize was the economic squeeze(利润等的缩减) and the recession(暴跌), which would mean there was less opportunity to separate because of the lack of housing and employment.
The phrase "levelled off" (Para. 1) most probably means ______.
A．increased
B．decreased
C．fluctuated
D．became stable
According to this law, changes in the prices of goods cause change in supply and demand. An increase in the price of the goods causes an increase in supply-then number of goods the producers make. Producers will make more goods when they can get higher prices for the goods. The producer makes more shoes as the price of shoes goes up. At the same time, an increase in the price of the goods causes a decrease in demand—the number of goods the consumers buy. This is because people buy less when the price is high. People buy fewer shoes as the price of shoes goes up. Conversely, a decrease in the price causes an increase in demand (people buy more shoes) and a decrease in supply (producers make fewer shoes).
Business firms look at both supply and demand when they make decisions about price and production. They look for the equilibrium point where supply equals demand. At this point, the number of shoes produced is 3000 and the price of the shoes is $30. $30 is the equilibrium price: at this price the consumers will buy all of the 3000 shoes which the producers make. If the producers increase the price of the shoes, or if they produce more than 3000 shoes, the consumers will not buy all of the shoes. The producers will have a surplus(过剩)—more supply than demand—so they must decrease the price in order to sell all of the shoes. On the other hand, if they make fewer than 3000 shoes, there will be a shoes shortage —more demand than supply—and the price will go up.
According to the Law of Supply and Demand, the equilibrium price is the best price for the good. The consumers and the producers will agree on this price because it is the only price that helps them both equally.
Why does an increase in price cause an increase in supply？ ______
A．Consumers buy more goods when prices are high.
B．Producers make more goods when prices are high.
C．Producers want to sell all of their goods.
D．Consumers will not buy all of the goods.

Temperatures at Hudson Bay have risen by one half degree Fahrenheit every decade since 1950. Winter ice on the bay melts three weeks earlier than it did just 25 years ago, which means three fewer weeks of polar bear mealtime. Result: Polar bears are 10 percent thinner and produce 10 percent fewer cubs than they did 20 years ago. And though climatologists hotly debate the causes behind Earth's Arctic meltdown, "these changes are startling and unexpected,' says James McCarthy, co-leader of the United Nations Intergovernmental Panel on Climate Change.
The plight of polar bears is just the tip to the iceberg when it comes to mounting evidence of global warming. "There's definitely a stark contrast with the way things were at the start of the 20th century," says atmospheric scientist Leonard Druyan, of Columbia University. Recent data show the volume of Arctic sea ice has shrunk 20 percent since the 1950s; glaciers around the world are melting at rapidly increasing rates. Rivers and lakes in North America, Asia, and Europe now freeze about nine days later and thaw 10 days earlier than they did a century ago.
Most scientists believe the only effective strategy to halt global warming is to drastically reduce emissions of powerful air pollutants like carbon dioxide, which accounts for two-thirds of all greenhouse gases. In the last 150 years, the surging use of fossil fuels coal, oil, and natural gas -- has released 270 billion tons of carbon into the air in the form. of carbon dioxide. Fortunately, oceans, plants, and soils absorb more than half of all atmospheric carbon dioxide -- without them world temperatures might have already soared at an alarming rate.
By saying "Spring is usually prime food time for 1,200 polar bears"？ (Line I, Para. 1), the author means that ______.
A．spring is usually a good time for polar bears to carry out their mating rituals
B．the polar bears usually eat a lot in the spring
C．spring is generally a good time to hunt polar bears
D．polar bears usually hibernate in the spring
Questions are based on the following passage．
Today， the poor aren "t just more likely to get divorced. They"re more likely to avoidmarriage entirely.
Earlier today， my colleague Derek Thompson argued that; it"s misleading to thinkof marriage as a "luxury good". Why？ Because luxury goods are something the rich buyand the poor can"t afford. But in the case of marriage the trend is more complex. The vastmajority of Americans tie the knot at some point in their lives， he argues. It"s just thatthose without a college education are far， far more likely to get divorced. Marriage is foreveryone; failed marriages are for the poor.
Bleak stuff. But it"s getting bleaker.
Derek"s post is based on a long-term study of young Baby Boomers， who were atleast 46 years old by 2010. But among younger Americans， marriage really is lookingmore and more like something you"d have to buy at Tiffany"s. According to 2012 CensusBureau report， which shows the percentage of men who have never married by age andincome， the less a guy earns nowadays， the less likely they are to have ever gotten married.
Well， that"s not 100 percent true. Among twenty-somethings there seems to be arich bachelor effect going on （or an overworked young professional effect， if you prefer）.
Those making $75，000 or more are somewhat less likely to have been married than thosemaking between $40，000 and $75，000.
This particular set of Census data unfortunately tells us much less about women andmarriage. The problem: Stay-at-home morns.
The key to remember， though， is that many educated， high-earuing women， the sortswho are likely to meet and marry educated and high-earning men， leave the workforce orgo part time once they have children. So a publicist who once made over $70，000 a yearmight only earn $20，000 if she decided to work fewer hours while caring for her childrenat home.
Here"s why this trend——not just the move towards divorce like Derek talked about，but the move from nuptials （婚礼 ） entirely——is so gloomy. Getting married， and stayingmarried， is one of the surest ways of securing a middle class life. By choosing not to wedin the first place， the poor are abandoning that chance at stability.
Why doesn‘t Derek Thompson think that marriage is a luxury good？ 查看材料
A.Because not everyone will get married eventually.
B.Because only rich people can afford to get married.
C.Because most people will get married regardless of their financial state.
D.Because lots of people can"t afford an expensive nuptial.
