By far the most common snake in Britain is the adder. In Scotland, in fact, there are no other snakes at all. The adder is also the only Britain snake with a poisonous bite. It can be found almost anywhere, but prefers sunny hillsides and rough open country, including high ground. In Ireland there are no snakes at all.
Most people regard snake bites as a fatal misfortune, but not all bites are serious, and very few are fatal: Sometimes attempts at emergency treatment turn out to be more dangerous than the bite itself, with amateurs heroically, but mistakenly, trying do-it-yourself surgery and other unnecessary measures.
All snakes have small teeth, so it follows that all snakes can bite, but only the bite of the adder presents any danger. British snakes are shy animals and are far more frightened of you than you could possibly be of them. The adder will attack only if it feels threatened, as can happen if you take it by surprise and step on it accidentally, or if you try to catch it or pick it up, which it dislike intensely. If it hears you coming, it will normally get out of the way as quickly as it can, but adders cannot move very rapidly and may attack before moving if you are very close.The effect of a bite varies considerably. It depends upon several things, one of which is the body-weight of the person bitten. The bigger the person, the less harmful the bite is likely to be, which is why children suffer far more seriously from snake bites than adults. A healthy person will also have better resistance against the poison.Very few people actually die from snake bites in Britain, and though these bites can make some people very ill, there are probably just as many cases of bites having little or no effect, as there are of serious illness.

If an adder hears you approaching, it will usually （　）.

A:move out of your path B:take no notice of you at all C:disappear very quickly D:wait until you are close then attack

How to Start a Small Business in the US

People from other countries often take America as the "land of opportunity". Americans, too, believe that the country gives no end of chances to those who want to open their own businesses. Today, many Americans are still trying hard to become small business people, although only one out of two remains in operation after the first two years.
Many people start their small businesses for the wrong reasons. They want to get away from the paper work of their present jobs or to exchange the responsibility of their present jobs for free life styles. But more, not less, paper work and responsibility come with ownership of a small business.
Thomas is the owner of the news magazine Mother Earth, which is now quite successful. He says that he had to work sixty hours without stopping when he was trying to bring out the first issue.
Thomas had waited for years after he came up with the idea for Mother Earth. During that time, he collected as much information as he could about his business. He borrowed books from the library, talked to successful people in the field, and began planning carefully the amount of money and the kinds and numbers of supplies he would need. When he finally opened with a capital of $1,500, he set up his office in the kitchen and his printing press in the garage. Owing to his devotion to business, his talent, and his skill in management, Mother Earth now has a circulation of 300,000.
Not all small businesses are doing as fine as Mother Earth. 50% of the 450,000 that start in America every year fail. Still, 95% businesses in the US can be called "small". Altogether these businesses amount to 40% of America’s gross national product.
According to the passage, which of the following is true of the small businesses in the US

A:All of them close down in the first two years. B:Most of them fail within the first two years. C:They all make big profits. D:Only half of them continue to operate after the first two years.

? ?Obesity can spread from person to person, much like a virus, researchers are reporting today. When one person gains weight, close friends tend to gain weight, too.
? ?Their study, published in The New England Journal of Medicine, involved a detailed analysis of a large social network of 12,067 people who had been closely followed for 32 years, from 1971 to 2003.
? ?The investigators knew who was friends with whom as well as who was a spouse or sibling or neighbor, and they knew how much each person weighed at various times over three decades. That let them reconstruct what happened over the years as individuals became obese. Did their friends also become obese? Did family members? Or neighbors?
? ?The answer, the researchers report, was that people were most likely to become obese when a friend became obese. That increased a person’s chances of becoming obese by 57 percent. There was no effect when a neighbor gained or lost weight, however, and family members had less influence than friends.
? ?It did not even matter if the friend was hundreds of miles away, the influence remained. And the greatest influence of all was between close mutual friends. There, if one became obese, the other had a 171 percent increased chance of becoming obese, too.
? ?The same effect seemed to occur for weight loss, the investigators say. But since most people were gaining, not losing, over the 32 years, the result was, on average, that people grew fatter.
? ?Dr. Nicholas A. Christakis, a physician and professor of medical sociology at Harvard Medical School and a principal investigator in the new study, said one explanation was that friends affected each others’ perception of fatness. When a close friend becomes obese, obesity may not look so bad.
? ?"You change your idea of what is an acceptable body type by looking at the people around you," Dr. Christakis said.
? ?The investigators say their findings can help explain why Americans have become fatter in recent years--each person who became obese was likely to drag along some friends.
? ?Their analysis was unique, Dr. Christakis said, because it moved beyond a simple analysis of one person and his or her social contacts and instead examined an entire social network at once, looking at how a person’s friend’s friends, or a spouse’s sibling’s friends, could have an influence on a person’s weight.
? ?The effects, he said, "highlight the importance of a spreading process, a kind of social contagion, that spreads through the network."
? ?Of course, the investigators say, social networks are not the only factors that affect body weight. There is a strong genetic component at work, too.
? ?Science has shown that individuals have genetically determined ranges of weights, spanning perhaps 30 or so pounds for each person. But that leaves a large role for the environment in determining whether a person’s weight is near the top of his or her range or near the bottom. As people have gotten fatter, it appears that many are edging toward the top of their ranges. The question has been why.
? ?If the new research is correct, it may say that something in the environment seeded what some call an obesity epidemic, making a few people gain weight. Then social networks let the obesity spread rapidly.
Which of the following statement about a friend’s influence is false according to the report?

A:Friends had more influence than family members on people who became obese. B:Even if the friend lives far away, the influence still remained. C:People were not likely to lose weight when they have skinny friends. D:The greatest influence of all was between close mutual friends.
