Fencing or Not
Wildlife fences are constructed for a variety of reasons including to prevent the spread of diseases, to protect wildlife from poachers(偷猎者), and to help manage small populations of threatened species. Human-wildlife conflict is another common reason for building fences. Wildlife can damage valuable farm animals and crops. Some species carry diseases of agricultural concern, and a few threaten human lives. At the same time, people kill wild animals for food, trade, or to defend lives or property, and human activities destroy wildlife habitat(栖息地). Separating people and wildlife by fencing can appear to be a mutually beneficial way to avoid such harmful effects. But in a paper in the journal Science, published recently, some scientists argue that fencing should only be used if worse comes to worst.
According to the scientists, although fencing can have conservation benefits, it also has costs. When areas of wildlife habitat are changed into islands, the resulting small and isolated populations tend towards extinction, and the resulting loss of larger-bodied species can affect interactions between species in ways that cause further local extinctions. Therefore, scientists are asking that conservationists carefully weigh up the biodiversity costs and benefits of new and existing fences.
In addition to fences’ ecosystem-wide impact, the scientists don’t think they always achieve their specific aims. Construction of fences to reduce human-wildlife conflict has been successful in some places but the challenges of appropriate fence design, location, construction, and protection mean that fences often fail to deliver the anticipated benefits. In some places, fences also provide poachers with a ready supply of wire for making traps.
A variety of alternative approaches, including better caring for farm animals, community-based crop-guarding, insurance and wildlife-sensitive land-use planning are suggested to reduce conflicts between people and wildlife without the need for fencing. Some projects working with local people and government agencies in Indonesia have shown that human-elephant conflict can be dramatically reduced without using fences.
The scientists conclude that as climate change increases the importance of facilitating wildlife mobility and conserving landscape connectivity, fence removal may become an important form of climate change preparation, and so fencing of wildlife should be avoided whenever possible.What does the underlined word “mutually” in Paragraph 1 probably mean________?

阅读下列短文，从每题所给的A、B、C和D项中，选出最佳答案。
We’ve talked about snails (蜗牛) and their slow move. But much of the time snails don’t move at all. They are in their shells (壳) —sleeping.
Hot sun will dry out a snail’s body. So at the least sign of hot sun, a snail draws its body into his shell. A snail will die in a heavy rain. So when it rains, a snail does the same thing, too. A snail can sleep for as long as it needs to. It spends all the winter months in its shell, asleep.
In the spring the snail wakes up. Its body, about three inches long, comes out from the shell. When hungry, the snail looks for food. Its eyes, at the end of the top feelers (触角), are very weak. But its sense (感觉) of smell is very strong. It helps the snail to find food and the new greens.
A snail’s mouth is no bigger than the point of a pin (大头针). Yet it has 256,000 teeth! The teeth are very small, and you can’t see them. If you put a snail in a hard paper box, it will eat its way out! And if a snail wears out its teeth, it will grow new ones.

I entered high school having read hundreds of books. But I was not a good reader.Merely bookish, I lacked a point of view when I read. Rather, I read in order to get a point of view. I searched books for good expressions and sayings, pieces of information, ideas, themes-anything to enrich my thought and make me feel educated. When one of my teachers suggested to his sleepy tenth-grade English class that a person could not have a "complicated idea" until he had read at least two thousand books, I heard the words without recognizing either its irony (嘲讽) or its very complicated truth. I merely determined to make a list of all the books I had ever
read. Strict with myself, I included only once a title I might have read several times.(How, after all, could one read a book more than once?) And I included only those books over a hundred pages in length. (Could anything shorter be a book?)
There was yet another high school list I made. One day I came across a newspaper article about an English professor at a nearby state college. The article had
a list of the "hundred most important books of Western Civilization." "More than
anything else in my life," the professor told the reporter with finality, "these books have made me all that I am." That was the kind of words I couldn't ignore. I kept the list for the several months it took me to read all of the titles. Most books, of course, I hardly understood. While reading Plato's The Republic, for example, I needed to keep looking at the introduction of the book to remind myself what the text was about.However, with the special patience and superstition (迷信) of a schoolboy, I looked at every word of the text. And by the time I reached the last word, pleased, I persuaded myself that I had read The Republic,and seriously crossed Plato off my list.
51.On heating the teacher's suggestion of reading, the writer thought______.
A. one must read as many books as possible.
B. a student should not have a complicated idea.
C. it was impossible for one to read two thousand books.
D. students ought to make a list of the books they had read
52. While at high school, the writer_________.
A. had plans for reading B. learned to educate himself
C. only read books over 100 pages D. read only one book several times
53. The underlined phrase "with finality" in the second paragraph probably means_________.
A. firmly B. clearly C. proudly D. pleasantly
54. The writer's purpose in mentioning "The Republic" is to________.
A. explain why it was included in the list.
B. describe why he seriously crossed it offthe list.
C. show that he read the books blindly though they were hard to understand
D. prove that he understood most of it because he had looked at every word
55. The writer provides two book lists to________.
A. show how he developed his point of view.
B. tell his reading experience at high school.
C. introduce the two persons' reading methods.
D. explain that he read many books at high school.
You're in a bit of a dilemma standing in front of the produce section of your local supermarket. In one hand, you're holding a conventionally grown Granny Smith apple.In your other hand, you have one that's been organically grown. Both apples are firm,shiny and green. Both provide vitamins and fiber, and both are free of fat, sodium and cholesterol.
The conventionally grown apple costs less and is a proven family favorite. But the organic apple has a label that says "USDA Organic". Does that mean it's better? Safer? More nutritious? Several differences between organic and non-organic foods exist. Become a better informed consumer for your next trip to the supermarket.
The word "organic" refers to the way farmers grow and process agricultural products, such as fruits, vegetables, grains, dairy products and meat. Organic farming practices are designed to encourage soil and water conservation and reduce pollution.Farmers who grow organic produce and meat don't use conventional methods to fertilize, control weeds or prevent livestock disease.
Here are other differences between conventional fanning and organic farming:
* Organic or not? Check the label.
The U.S. Department of Agriculture (USDA) has established an organic certification program that requires all organic foods to meet strict government standards. These standards regulate how such foods are grown, handled and processed.Any farmer or food manufacturer who labels and sells a product as organic must be USDA certified as meeting these standards. Only producers who sell less than $5,000 a year in organic foods are exempt (免除) from this certification.
If a food bears a USDA Organic label, it means it's produced and processed according to the USDA standards. The seal is voluntary, but many organic producers
use it.
46. The main purpose of the passage is_________.
A. to promote the sales of organic food
B. to inform people organic food is better for their health
C. to persuade people to become informed consumers
D. to compare conventional and organic foods
47. According to the passage, organic farming is intended to_________.
A. improve the quality of the soil and water
B. take the place of the traditional agriculture entirely
C. adopt eco-friendly methods to grow plants and feed animals
D. prevent livestock from getting disease more effectively
48. According to the passage, the conventionally grown apple_________.
A. costs less but tastes worse than an organic one
B. doesn't look the same as an organic one
C. has proven itself acceptable by the family
D. contains more fat, sodium and cholesterol
49. Which of the following methods belongs to organic farming?
A. Using chemicals to kill insects and prevent disease.
B. Using rotted plants as fertilizer to promote plant growth.
C. Using growth hormones to speed up animals' growth.
D. Using pests to reduce insects and disease.
50. From the passage we know the organic certification program________.
A. is not meant for all producers of produce
B. makes it compulsory to attach a USDA Organic label
C. sets restrictions on the sales of organic produce
D. requires all foods to satisfy the strict government standards

Living an Adventurous Life
Nearly ten years ago, I was told that I had a brain tumor (瘤), and this experience changed my attitude about adventure forever. I thought that I was going to die and that all my adventures were over. I did not have a brain tumor, it turned out, but rather multiple sclerosis (多发性硬化症), which meant that, although they were not over,the nature of my adventures could have to change.
Each morning that I wake up is a fresh event, something that I might not have
had. Each gesture that I make carries the weight of uncertainty and demands significant attention: buttoning my shirt, changing a light bulb, walking down stairs. I might not be able to do it this time. If I could not delight in them, they would likely drown me in anger and in self-pity.
I admire the grand adventures of others. I read about them with interest. With Peter Matthiessen I have hiked across the Himalayas to the Crystal Mountain. I have walked with Annie Dillard up, down, into, and across Tinker Creek in all Seasons. David Bain has gone with me along 110 miles of Philippine coast, and Ed Abbey has
rowed me down the Colorado River, I enjoy the adventures of these courageous figures, who can strike out on difficult trips - 2 miles, 250 miles, 3000 miles - ready to bear cold and tiredness - indeed not just to bear but to celebrate.
But as for me, I can no longer walk very far from the armchair in which I read. Some days I don't even make it to the backyard. And yet I'm unwilling to give up the adventurous life, the difficulty of it, even the pain, the anxiety and fear, aud the sudden brief lift of spirit that makes a hard journey more attractive.
I refine adventure, make it smaller and smaller. And now, whether I am moving on my hands and knees across the dining room to help my cat, lying wide-eyed in the dark battling another period of sadness, gathering flowers from the garden, meeting a friend for lunch, I am always having the adventures that are mine to have.

Large companies need a way to reach the savings of the public at large. The same problem, on a small scale, faces practically every company trying to develop new products and create new jobs. There can be little prospect of raising the sort of sums needed from friends and people we know, and while banks may agree to provide short-term finance, they are generally unwilling to provide money on the permanent basis for long-term projects. So companies turn to the public, inviting people to lend them money, or take a share in the business through the Stock Exchange. By doing so, they can put the saving of individuals and institutions into circulation both at home and overseas.
When the saver needs his money back, he does not have to go to the company with whom he originally placed it. Instead, he sells his shares through a stockbroker（股票经纪人） to some other saver who is seeking to invest his money.
Many of the services needed both by industry and by each of us are provided by the government or by local authorities. Without hospitals, roads, electricity, telephones, railways, this country could not function. All these require continuous spending on new equipment and new development if they are to serve us properly, requiring more money than is raised through taxes alone. The government, local authorities, and nationalized industries therefore frequently need to borrow money to finance major capital spending, and they, too, come to the Stock Exchange.
There is hardly a man or woman in this country whose standard of living does not depend on the ability of his or her employers to raise money to finance new development. In one way or another, the new money must come from the savings of the country. The Stock Exchange exists to provide a channel through which these savings can reach those who need finance.
51. Almost all companies involved in new production and development most .
A. rely on their own resources
B. persuade the banks to provide long-term finance
C. borrow large sums of money from friends and people they know
D. depend on the population as a whole for finance
52. The money which enables these companies to go ahead with their projects is .
A. repaid to its original owners as soon as possible
B. raised by selling of shares in the companies
C. exchanged for the ownership in the Stock Exchange
D. invested in different companies in the Stock Exchange
53. When the savers want their money back they should .
A. ask another company to obtain their money for them
B. look for other people to borrow money from
C. put their shares in the company back on the market
D. transfer their money to a more successful company
54. All the essential services on which we depend are .
A. run by the government or our local authorities
B. in constant need of financial support
C. financed wholly by raising taxes
D. unable to provide for the needs of the population
55. The Stock Exchange makes it possible for the government, local authorities and nationalized industries .
A. to borrow as much money as they wish
B. to make certain everybody saves money
C. to raise money to finance new development
D. to make certain everybody lends money to them.
