    Windbreaks are barriers (屏障) formed by trees and other plants. Farmers plant these barriers around their fields, which help prevent the loss of soil, stop the wind from blowing soil away. They also keep the wind from damaging or destroying crops. Besides, extra trees and plants can be cut down and used or sold for wood.

    Windbreaks can be highly valuable for protecting grain crops. For example, in parts of West Africa grain harvests were as much as twenty percent higher in fields protected by windbreaks compared to fields without them.

    But here is something interesting about windbreaks. They seem to work best when they allow some wind to pass through the barrier of trees or plants around a field. If not, then the movement of air close to the ground will lift the soil. Then the soil will be blown away. For this reason, a windbreak works best if it contains only 60 to 80 percent of the trees and plants that would be needed to make a solid line. An easy rule to remember is that windbreaks can protect areas up to 10 times the height of the tallest trees in the windbreak.

    There should be at least two lines in each windbreak. One line should be large trees. The second line, right next to it, can be shorter trees or other plants with leaves. Locally grown trees and plants are considered the best choices for windbreaks. Trees reduce the damaging effects of wind and rain. Their roots help protect soil from being washed away. And trees can provide animals outdoors with shade from the sun.

(1)、The advantages of building a windbreak are as follows EXCEPT _____.
A、keeping the wind from destroying grain crops B、increasing the production of grain harvests C、providing humans with shade from the sun D、reducing the damaging effects of wind and rain
(2)、The author thinks windbreaks are interesting because ______.
A、the movement of air lifts the soil B、windbreaks allow some wind to pass through C、large trees are lined with short ones D、windbreaks can stop the wind getting through
(3)、If the trees grow to a height of 30 feet, the areas the windbreak can protect are ______.
A、100 square feet B、150 square feet C、240 square feet D、300 square feet
(4)、What can be inferred from the text?
A、Extra trees and plants can be cut down for wood. B、The environment is going from bad to worse. C、Trees and plants from abroad are the best for windbreaks. D、Windbreaks can contribute to agriculture harvests.

    I don't ever want to talk about being a woman scientist again. There was a time in my life when people kept asking me stories about what it's like to work in a field under the control of men. I was never very good at telling those stories because truthfully I never found them interesting. What I do find interesting is the existence of the universe, the shape of space time and the nature of black holes.

    At 19, when I began studying astrophysics(天体物理学), it did not bother me in the least to be the only woman in the classroom. But while earning my Ph.D. at MIT and then as a post-doctor doing space research, the problem started to bother me. My every achievement—jobs, research papers, awards—was viewed from the angle of gender (性别) politics. So were my failures.

    Then one day a few years ago, out of my mouth came a sentence that would finally become my reply to any and all provocations(挑衅): I don't talk about that any more. It took me 10 years to get back the confidence I had at 19 and to realize that I didn't want to deal with gender problems. Why should removing sexism be yet another terrible burden on every female scientist? After all, I don't study sociology or political theory.

    Today I research and teach at Barnard, a women's college in New York City. Recently, someone asked me how many of the 45 students in my class were women. You cannot imagine my satisfaction at being able to answer, 45. I know some of my students worry how they will manage their scientific research and a desire for children. And I don't take no notice of those concerns. Still, I don't tell them “war” stories. Instead, I have given them this: the scene of their physics professor heavily pregnant (怀孕)doing physics experiments. And in turn they have given me the image of 45 women driven by a love of science. And that's a sight worth talking about.

    Nowadays, top performing sportsmen earn huge amount of money as compared to people in other professions. Some people consider it a rational approach. However, there are a few who think it is unjustifiable.

    Some people think sports professionals with outstanding performance should be overpaid as it is a short-lived career which requires rigorous hard work as compared to other professions. This field demands a strict, disciplined life with extensive physical efforts, consistent practice, a fixed diet schedule to bring pride and glory to the country. Due to such tough requirements, people in this field have an average career span of 10-15 years. As sports professionals have limited tenure, they should be rewarded with high monetary gains to acknowledge their excellent performance.

    However, there are a few who think that top performing sportsmen and women should not have high salaries as it is a biased approach. They feel that there are other critical professions which are more valuable to the country as compared to the sports field. For example, the professions, like doctors, social worker, works for the betterment of the society. Their efforts not only help to reduce the social issues prevailing in the community, but they also contribute in providing a healthy environment. As a result, they significantly contribute to the growth of the country. Henceforth, their efforts should be equally recognized along with the sports professionals.

    In my opinion, although there are some logical reasons for huge earnings of the top performing players, people from other professions should also be equally appreciated in terms of lucrative monetary benefits for their outstanding contribution. As all the professions are critical in their own field and contributes to the overall development of the country.

    To conclude, sports people delivering excellent performance should not be overpaid in comparison to other professionals who make a significant contribution to the society.

    As people age, the body changes in all sorts of predictable ways. Brains can slow. Wounds take longer to recover. And sleep patterns(模式) shift, too. This can come as news to many, says Michael V. Vitiello, a psychologist at the University of Washington who is expert in sleep in aging.

The most noticeable—and often most annoying—changes are how sleep and wake-up times change and sleep gets lighter, often beginning in middle age. Gone are weekend sleep to 11 a.m. and the ability to sleep through a noisy garbage truck down the block.

But not every restless night can be ignored. Studies have found that poor sleep can create a particular threat to older adults—Falls, depression and anxiety, problems with memory, and increased suicide(自杀) risk are among the effects of sleep issues in this population group that researchers have found. But scientists are still unsure why those risk connections exist.

    What is clear is the connection between good sleep and psychological well-being in older adults. A 2010 study showed us that connection when it came to sleep quality, but sleep quantity didn't show the same effects. And that, experts say, may be the key to understanding sleep as you age. If you're sleeping less, but don't feel negative effects out of bed, the changes you notice may just be normal age-related.

    Over time, Vitiello says, sleep patterns simply change. "A lot of older adults recognize that they don't sleep the same as they did when they were 18, but they can still function and they're OK. And all is well with the universe."
