单选题A smile is a strong sign of a friendly and open attitude and a willingness to communicate. It is a positive, silent sign sent with the hope the other person will smile back. When you smile, you show you have noticed the person in a positive way. The result? That person will usually smile back. You might not realize a closed position is the cause of many conversational problems. A common closed position is sitting with your arms and legs crossed and your hand covering your mouth or chin. This is often called the "thinking pose". Ask yourself this question: Are you going to interrupt someone who appears to be deep in thought? This position gives off "stay away" signs and prevents your main "sign sender" (your mouth) from being seen by others looking for inviting conversational signs. The open body position is most effective when you place yourself within communicating distance of the other person—that is, within about five feet. Take care, however, not to enter someone"s "personal space" by getting too close, too soon. Leaning forward a little while a person is talking shows your interest and how you are listening to what the person is saying. By doing this, you are saying: I hear what you"re saying, and I"m interested in—keep talking! Often people will lean back with their hands over their mouth, chin, or behind their head in the "thinking" pose. This position gives off signs of judgment, doubt, and lack of interest from the listener. Since most people do not feel comfortable when they think they are being judged, this leaning-back position serves to prevent the speaker from continuing. In many cultures the most common form of first contact between two people is a handshake. Be the first to extend your hand in greeting. Couple this with a friendly "Hello", a nice smile, and your name and you have made the first step to open the lines of communication. Eye contact should be natural, not forced or overdone. Direct eye contact shows you are listening to the other person and that you want to know about her.

单选题Questions 14-17 are based on the following dialogue.

单选题 Sometime in the middle of the 15th century, a well-to-do merchant from London buffed more than 6,700 gold and silver coins on a sloping hillside in Surrey. He was fleeing the War of the Roses and planned to return during better times. But he never did. The coins lay undisturbed until one September evening in 1990, when local resident Roger Mintey chanced upon them with a metal detector, a device used to determine the presence of metals. Mintey's find—much of which now sits in the British Museum-earned him roughly $350,000, enough to quit his job with a small manufacturer and spend more time pursuing lost treasure. But digging up the past is controversial in Britain. In many European countries, metal detectorists, or people using metal detectors, face tough regulations. In the U.K., however, officials introduced a scheme in 1997 encouraging hobbyists to report their discoveries (except for those falling under the definition of treasure, like Mintey's find, which they are required to report)—but allowing them to keep what they find, or receive a reward. Last year, a hidden store was uncovered in a field outside Birmingham. It consists of more than 1,500 gold and silver objects from the seventh century and was valued at more than $4.5 million. While local museums hurry to raise enough money to keep the find off the open market, it sits in limbo, owned by the Crown but facing claims by the landowner and the metal detectorist who found it. The find marks the latest battleground in the increasingly heated conflict between the country's 10,000-20,000 metal detectorists and the museum workers determined to protect its precious old objects. Supporters say the scheme stems the loss of valuable information about precious old objects, while opponents argue that metal detectorists don't report everything. The debate centers on the larger question of who owns the past. "There's been a slow move over the centuries that precious old things belong to us all," says Professor Christopher Chippindale of Cambridge University. But in Britain at least, the temptation of buried treasure could change all that.

单选题A break through in the provision of energy from the sun for the European Economic Community (EEC) could be brought forward by up to two decades, if a modest increase could be provided in the EEC's research effort in this field, according to the senior EEC scientists engaged in experiments in solar energy at EEC's scientific laboratories at Lspra, near Milan. The senior West German scientist in charge of the Community's solar energy programme, Mr. Joachim Gretz, told journalists that at present levels of research spending it was most unlikely that solar energy would provide as much as three per cent of the Community's energy requirements even after the year 2000. But he said that with a modest increase in the present sums devoted by the EEC to this work it was possible that the breakthrough could be achieved by the end of the next decade. Mr. Gretz calculates that if solar energy only provided three percent of the EEC's needs, this could still produce a saving of about a billion pounds in the present bill for imported energy each year. And he believes that with the possibility of utilizing more advanced technology in this field it might be possible to satisfy a much bigger share of the Community's future energy needs. At present the EEC spends about $2.6 millions a year on solar research at Lspra, one of the EEC's official joint research centres, and another $3 million a year in indirect research with universities and other independent bodies.
