Planting trees around poultry farms can improve air and water quality -- and relations with neighbors. Research has shown that just three rows of trees near poultry houses can reduce the release of dust and ammonia(氨). They can also reduce the strong smell of ammonia gas.
The trees take dust, ammonia and odors in their leaves. They also provide shade from the sun, so they reduce cooling costs in summer. And they act as a windbreak, so they reduce heating costs in winter. Trees can also improve water quality around farms by removing pollutions from soil and groundwater.
Several years ago, people were objecting to the odor of poultry farms on the Delmarva Peninsula in the eastern United States. Delmarva is where the states of Delaware, Maryland and Virginia come together. Two thousand farms there can each house an average of seventy-five thousand chickens.
Traditionally the farms used windows to provide fresh air in the chicken houses. Farmers rarely planted trees or tall crops around the buildings, so there would be no barrier to the airflow. But then farms began to use new ventilation systems. Instead of windows, the new systems used tunnel fans to circulate air. The fans directed airflow from the poultry houses toward the homes of neighbors.
Researchers began dealing with the problem in two thousand. They found that over a period of six years, planting three rows of trees reduced total dust and ammonia by more than half. And they found that smells were reduced by eighteen percent.
Farmers may think trees will take too long to grow and be effective. But some trees can grow quickly. At least one-third of the Delmarva farms have planted trees, technically known as vegetative environmental buffers. The idea offers a way to cut pollution, save money and energy, and make the neighbors happy.

Children start out as natural scientists, eager to look into the world around them. Helping them enjoy science can be easy; there’s no need for a lot of scientific terms or expensive lab equipment. You only have to share your children’s curiosity(好奇). Firstly, listen to their questions. I once visited a classroom of seven-year-olds to talk about science as a job. The children asked me “textbook questions” about schooling, salary(薪水) and whether I liked my job. When I finished answering, we sat facing one another in silence. Finally I said, “Now that we’re finished with your lists, do you have questions of your own about science?”
After a long pause, a boy raised his hand, “Have you ever seen a grasshopper(蚱蜢) eat? When I try eating leaves like that, I get a stomachache. Why?”
This began a set of questions that lasted nearly two hours.
Secondly, give them time to think. Studies over the past 30 years have shown that, after asking a question, adults typically wait only one second or less for an answer, no time for a child to think. When adults increase their “wait time” to three seconds or more, children give more logical(符合逻辑的), complete and cre ative answers.
Thirdly, watch your language. Once you have a child involved in a science discussion, don’t jump in with “That’s right” or “Very good”. These words work well when it comes to encouraging good behavior(行为). But in talking about science, quick praise can signal that discussion is over. Instead, keep things going by saying “That’s interesting” or “I’d never thought of it that way before”, or coming up with more questions or ideas.
Never push a child to “Think”. It doesn’t make sense, children are always thinking, without your telling them to. What’s more, this can turn a conversation into a performance. The child will try to find the answer you want, in as few words as possible, so that he will be a smaller target(目标) for your disagreement.
Lastly, show; don’t tell. Real-life impressions of nature are far more impressive than any lesson children can learn from a book or a television program. Let children look at their fingertips through a magnifying glass(放大镜), and they’ll understand why you want them to wash before dinner. Rather than saying that water evaporates(蒸发), set a pot of water to boil and let them watch the water level drop.
According to the passage, children are natural scientists, and to raise their interest, the most important thing for adults to do is _______.

A．to let them see the world around

B．to share the children’s curiosity

C．to explain difficult phrases about science

D．to supply the children with lab equipment

Winter depression (or winter blues) is a common affliction (折磨) for those who live in our northern climate. Its clinical name is seasonal affective disorder (or SAD) and up to 5% of the population (especially in northern states) may suffer from it. Seasonal affective disorder is characterized by feelings of sadness and depression that occur in the winter months when the temperatures drop and the days grow short . The depression is often associated with excessive eating or sleeping and weight gain. Women are twice to three times more likely to suffer from the winter blues than men.
There are many effective treatments for winter depression, some of which you can do to help yourself. Increasing your daily exposure to as much natural light as possible can be helpful to many. Any time that you have the opportunity to gain access to more sunlight in the winter months, you should try to do so. Taking walks throughout the day (even if you don’t normally do so), sitting next to a south-facing window at your office, in a classroom, or at home will increase your sunlight exposure. Exercising next to a window or outdoors (when possible) is another activity that can help.
Although it may be difficult to do, maintaining your schedule and lifestyle will help to keep the depression at bay. A regular pattern of sleep is the most important thing to maintain. It may be helpful, for instance, to have your bedroom lights on a timer to turn on a half-hour before you wake. This may help in waking at a regular time every morning, when it is still dark outside in the winter months.
Light therapy has shown to be an effective treatment for seasonal affective disorder. While you can purchase expensive, specialized light therapy lighting fixtures for your home or office, some inexpensive alternatives are also available. Another lighting technique to try is to replace commonly used light bulbs in your home with brighter full spectrum (also known as broad spectrum) light bulbs. While more expensive than regular light bulbs, these bulbs provide light that is similar to natural sunlight.
If none of these techniques seem to help your depressive symptoms, you should consider consulting your family physician or a mental health professional. The winter blues are a form of depression and can be readily treated w ith medications or psychotherapy when other self-help methods aren’t effective. Don’t be afraid to talk about this condition with a professional; it’s nothing to be ashamed or afraid of. With a little effort, the winter blues can be beaten

When next year’s crop of high-school graduates arrive at Oxford University in the fall of 2009, they’ll be joined by a new face: Andrew Hamilton, the 55-year-old provost(教务长) of Yale, who’ll become Oxford’s vice-chancellor——a position equal to university president in America.
Hamilton isn’t the only educator crossing the Atlantic. Schools in France, Egypt, Singapore, etc. have also recently made top-level hires from abroad. Higher education has become a big and competitive business nowadays, and like so many businesses, it’s gone global. Yet the talent flow isn’t universal. High-level personnel(人员) tend to head in only one direction: outward from America.
The chief reason is that American schools don’t tend to seriously consider looking abroad. For example, when the board of the University of Colorado searched for a new president, it wanted a leader familiar with the state government, a major source of the university’s budget. “We didn’t do any global consideration,” says Patricia Hayes, the board’s chair. The board finally picked Bruce Benson, a 69-year-old Colorado businessman and political activist(活动家) who is likely to do well in the main task of modern university presidents: fund-raising. Fund-raising is a particularlly American thing, since U.S. schools rely heavily on donations. The fund-raising ability is largely a product of experience and necessity.
Many European universities, meanwhile, are still mostly dependent on government funding. But government support has failed to keep pace with rising student numbers. The decline in government support has made fund-raising an increasingly necessary ability among administrators (管理人员), and has hiring committees hungry for Americans.
In the past few years, well-known schools around the world have joined the trend. In 2003, when Cambridge University appointed Alison Richard, another former Yale provost, as its vice-chancellor, the university publicly stressed that in her previous job she had overseen “a major strengthening of Yale’s financial position.”
Of course, fund-raising isn’t the only skill outsiders offer. The globalization of education means more universities will be seeking heads with international experience of some kind to promote international programs and attract a global student body. Foreigners can offer a fresh perspective(视角) on established practices.
What is the current trend in higher education discussed in the passage?

A．Institution worldwide are hiring administrators from the US.

B．A lot of activists are being hired as administrators

C．American universities are enrolling more international students.

D．University presidents are paying more attention to funding-raising.

What is the chief consideration of American universities when hiring top-level administrators?

A．The political correctness.	B．Their ability to raise funds.
C．Their fame in academic circles.	D．Their administrative experience.

What do we learn about European universities from the passage?

A．The tuitions(学费) they charge h

ave been rising considerably.

B．Their operation is under strict government control.

C．They are strengthening their position by globalization.

D．Most of their money comes from the government.

In what way do top-level administrators from abroad contribute to university development?

A．They can improve the university’s image.

B．They will bring with them more international personnel.

C．They will view a lot of things from a new angle.

D．They can set up new academic subjects.

Which of the following would make the best title of the passage?

A．Higher Education Globalization	B．Global Headhunting In Higher Education
C．Global Higher Education Cooperation	D．Universal Higher Education Development

Hello. It’s one of the first words we learn as babies, yet it’s one of the last ones we think to use as adults. That’s unfortunate, b 48 saying hello is more than just saying hello—it is recognition of another’s worth. How might the world change—how might we change—if we mastered this word? To find o 49 , I spent one month saying hello to every person I met. Here’s what I’ve learned. It can boost （促进） productivity. In one of the few studies ever done on this subject, Allan Allday, a 50 assistant professor of special education at Oklahoma State University, had middle school teachers greet their students individually each morning. This exchange of greetings raised the kids’ productivity. School went from impersonal to p 51 , and that resulted in more class participation and better grades.
Environments influence friendliness, One study found that people in the city were more likely to kiss one hand with a stranger than those in the countryside. And researchers say，pleasure environments generally encourage more smiles and hellos t 52 unpleasant ones. My experience was similarly. Whatever the reason, my urban hellos were answered far l 53 often than my rural one. Similarly, people in vacation spots, l 54 the Jersey Shore, were far friendlier than those hurrying work downtown.
It’s a form of universal health insurance. It’s impossible to say hello w 55 smiling. And smiling has been shown to lower blood pressure, relieve stress and boost happiness. Apparently, a smile creates a similar effect in the recipient （接受者）。

A．Teachers.	B．Parents.
C．Students.	D．Headmasters.

A．IFAW	B．Penguin Group
C．PGA Junior League Golf	D．Special Olympics
