May. As you can see on the screen, heavy rain and the risk of severe thunderstorms is forecast through Friday from the western Gulf Coast north and eastward through the lower and mid Mississippi Valley. Much of this area has already received heavy rain over the past few weeks, thus flash flooding is possible. Additional rain in Friday will also exacerbate the widespread main stem river flooding that is ongoing.

Where is the report probably being broadcasted？

A．On TV

B．On the radio

C．Through telephone

D．By voiced mail

And the beauty of scientific theories is they help us to 【M1】______ organize our thinking about a broad arrange of observations and 【M2】______ events. Imagine how life might be like for a researcher who plugs 【M3】______ away at collecting data and cataloging fact after fact with organizing 【M4】______ this information around a set of concepts and propositions. Chances are that this person would eventually be swamped by seemingly unconnected facts, thus qualifying as a trivia expert who lacks "big 【M5】______ picture." So theories are of critical importance to developmental psychology, for each of them provides us with a "lens" which we 【M6】______ might interpret any number of specific observations about developing individuals. What are the characteristics of a good theory？ Ideally, it should be concise, or parsimonious, and thus be able to explain a broad 【M7】______ range of phenomena. A theory with few principles that accounts of a 【M8】______ large number of empirical observations is much more useful than a second theory that requires many more principles and assumptions to explain the same number of observations. In addition, good theories are falsifiable — that is, capable of making explicit predictions about future events so that the theory can be supported or disconfirmed. And, as implied by the falsifiability criterion, good theories do not limit themselves to which is already known. Instead, they are 【M9】______ heuristic — meaning that they build on existing knowledge by continuing to generate testable hypotheses that, if confirmed by future research, will lead to a much rich understanding of the 【M10】______ phenomena under investigation.

ppear. They share a number of similarities with each other—as well as some important differences.

Manned submersibles.(潜水器), like spaceships, must maintain living conditions in an unnatural environment. But while a spaceship must simply be sealed against the vacuum of space, a submersible must be able to bear extreme pressure if it is not to break up in deep water.

In exploring space, unmanned vehicles were employed before astronauts. In undersea exploration, on the other haled, men paved (铺路) the way, and only recently have unmanned remote-operated vehicles (ROVs) been put to use.

One reason for this is that communicating with vehicles in orbit is much easier than talking to those underwater. A vacuum is an ideal medium for radio communications, but underwater communications are limited to much slower sound waves. Thus, most undersea vehicles—particularly ROVs—operate. at the end of long process.

For a similar reason, knowing where you are undersea is much more difficult than in space. A spaceship's position can be located by following its radio signal, or by using telescopes and radar. For an undersea vehicle, however, a special network of sonar (声纳) devices most be laid out in advance on the ocean floor in the area of a dive to locate the vehicle's position.

Though undersea exploration is more challenging than outer space in a number of respects, it has a distinct advantage: Going to the ocean doesn't require the power necessary to escape Earth's gravity. Thus, it remains far less expensive.

People did not begin to use unmanned vehicles in undersea exploration until recently because of ______.

A．the ocean depths

B．the communication problem

C．the movement of waves

D．the problem of vacuum

Women's education may be unusual territory for economists, but enhancing women's contribution to development is actually as much an economic as a social issue. And economics, with its emphasis on incentives (激励), provides guideposts that point to an explanation for why so many girls are deprived of an education.

Parents in low-income countries fail to invest in their daughters because they do not expect them to make an economic contribution to the family: girls grow up only to marry into somebody else's family and bear children. Girls are thus seen as less valuable than boys and art kept at home to do housework while their brothers are sent to school the prophecy (预言)becomes self-fulfilling, trapping women in a vicious circle (恶性循环) of neglect.

An educated mother, on the other hand, has greater earning abilities outside the home and faces an entirely different set of choices. She is likely to have fewer but healthier children and can insist on the development of all her children, ensuring that her daughters are given a fair chance. The education of her daughters then makes it much more likely that the next generation of girls, as well as of boys, will be educated and healthy. The vicious circle is thus transformed into a virtuous circle.

Few will dispute that educating women has great social benefits. But it has enormous economic advantages as well. Most obviously, there is the direct effect of education on the wages of female workers. Wages rise by 10 to 20 per cent for each additional year of schooling. Such big returns are impressive by the standard of other available investments, but they are just the beginning. Educating women also has a significant impact on health practices, including family planning.

The author argues that educating girls in developing countries is ______.

A．troublesome

B．labor-saving

C．rewarding

D．expensive

Factors Influencing Marriage

The common view in social science of love relationships is not that opposites attract each other but that like attracts like. People fall in love with others who share their interests and tastes and whose personalities are similar. Hill, Rubin, and Peplau found only slight support for this view. On a great many characteristics, couples were not alike. On others, couples were only somewhat alike. Couples did tend to be about the same age, to be equally good-looking, to have similar IQ scores, to be of the same religion , and to want the same number of children. But on each of these things, quite a few couples differed from one another. In fact, on only one question did most agree on. whether they were "in love".

The early interviews failed to find that being alike was very important in bringing couples together. The follow-up interviews found that similarities were much more important in keeping couples together. Those who were together after two years were much more closely matched than couples who broke up, especially in terms of age, IQ, college plans, and looks. Thus, couples were much more likely to break up if one person was a lot smarter, better looking, or older. It is easy to imagine why these differences would matter. If one person is much smarter or more mature than the other, this could cause conflicts. If one person is much better looking, he or she will have more chances for other relationships.

Yet other things that would seem as important turned out not to matter. Those who stayed together differed not at all from those who broke up in how alike they were on religion, sex role ideas, beliefs about sex, idealism, or the number of children they wanted. Surely, one might suppose that marked differences in sex role attitudes could cause friction or that religious differences might lead to breakups. But there was no evidence of this.

In fact, conflict was not one of the main reasons people gave for breaking up. Most said they broke up because they got bored with the other person. Often this caused one of the pair to become interested in someone else, thus prompting (促进) the split (分裂). Perhaps surprisingly, the woman got involved with someone else far more often than the man. Also, women were much more likely to suggest a breakup than men, regardless of the grounds. However, people were more likely to remain friends after the breakup if the man asked for the split. This suggests that the male ego is more sensitive to rejection.

In a marriage, conflicts are often caused by the diversity of intelligence.

B．Wrong

rnight camp by a river. Providing you take care to keep insects away, this can be as healthy a place as any. Much as you might feel you need a good wash, one trap not to fall into, though, is the use of soap or shampoo. These may make you feel good, but actually give off unnatural smells in the jungle which act as a magnet to insects, thus increasing the chances of your getting bitten. Better to actually go in for a dip, being careful to dry off and re-apply your anti-insect cream immediately afterwards.

You hear a man talking to a group of people who are going on an expedition into the rainforest. What does he advise them against？ ......

A．sleeping in places where insects are found.

B．using substances which attract insects.

C．bathing in areas where insects are common.
