单选题You must have been troubled by when to say "I love you" because it is one of the greatest puzzles in our life. What if you say it first and your partner doesn't love you back? Or if they do say it but you don't feel they mean it? Being the first to declare your love can be nerve-racking (紧张) and risky and can leave you feeling as vulnerable as a turtle with no shell. But is the person who says it first really in a position of weakness? Doesn't it pay to hold back, play it cool and wait until the other half has shown their hand frst? "A really good relationship should be about being fair and being equal, " says psychologist Sidney Crown. "But love is seldom equal. " All relationships go through power struggles but, he says, if a love imbalance continues for years, the rot will set in. "That feeling of 'I've always loved you more' may be subverted (颠覆，破坏) for a time, but it never goes away completely and it often emerges in squabbling (大声争吵). " In love, at least, the silent, withholding type is not always the most powerful. "The strongest one in a relationship is often the person who feels confident enough to talk about their feelings, " says educational psychologist Ingrid Collins. Psychosexual therapist Paula Hall agrees. "The one with the upper hand is often the person who takes the initiative. In fact, the person who says 'I love you' first may also be the one who says 'I'm bored with you' first. " Hall believes that much depends on how "I love you" is said and the motivation of the person saying it. "Is it said when they're drunk? Is it said before their partner flies off on holiday, and what it really means is 'Please don't be unfaithful to me'? By saying 'I love you' , they really saying 'Do you love me?' If so, wouldn't it just be more honest to say that?" Collins agrees that intention is everything. "It's not what is said, but how it's said. What it comes down to is the sincerity of the speaker. /

单选题The view over a valley of a ting village with thatched roof cottages around a church; a drive through a narrow village street lined with thatched cottages painted pink or white; the sight over the rolling hills of a pretty collection of thatched farm buildings-these are still common sights in parts of England. Most people will agree that the thatched roof is an essential part of the attraction of the English countryside. Thatching is in fact the oldest of all the building crafts practised on the British Isles (英伦诸岛). Although thatch has always been used for cottage and farm buildings, it was once used for castles and churches, too. Thatching is a solitary (独自的) craft, which often runs in families. The craft of thatching as it is practised today has changed very little since the Middle Ages. Over 800 full-time thatchers are employed in England and Wales today, maintaining and renewing the old roofs as well as thatching newer houses. Many property owners choose thatch not only for its beauty but because they know it will keep them cool in summer and warm in winter. In fact, if we look at developing countries, over half the world lives under thatch, but they all do it in different ways. People in developing countries are often reluctant to go back to traditional materials and would prefer modem buildings. However, they may lack the money to allow them to import the necessary materials. Their temporary mud huts with thatched roofs of wild grasses often only last six months. Thatch which has been done the British way lasts from twenty to sixty years, and is an effective defence against the heat.

单选题{{B}}Text 1{{/B}} Once it was possible to define male and female roles easily by the division of labour. Men worked outside the home and earned the income to support their families, while women cooked the meals and took care of the home and the children. These roles were firmly fixed for most people, and there was not much opportunity for men or women to exchange their roles. But by the middle of this century, men's and women's roles were becoming less firmly fixed. In the 1950s, economic and social success was the goal of the typical American. But in the 1960s developed a new force called the counterculture. The people involved in this movement did not value the middle-class American goals. The counterculture presented men and women with new role choices. Taking more interest in child care, men began to share child-raising tasks with their wives. In fact, some young men and women moved to communal homes or farms where the economic and child care responsibilities were shared equally by both sexes. In addition, many Americans did not value the traditional male role of soldier. Some young men refused to be drafted as soldiers to fight in the war in Vietnam. In terms of numbers, the counterculture was not a very large group of people. But its influence spread to many parts of American society. Working men of all classes began to change the economic and social patterns. Industrial workers and business executives alike cut down on overtime work so that they could spend more leisure time with their families. Some doctors, lawyers, and teachers turned away from high paying situations to practice their professions in poorer neighbourhoods. In the 1970s, the feminist movement, or women's liberation, produced additional economic and social changes. Women of all ages and at all levels of society were entering the work force in greater numbers. Most of them still took traditional women's jobs such as public school teaching, nursing, and secretarial work. But some women began to enter traditionally male occupations: police work, banking, dentistry, and construction work. Women were asking for equal work, and equal opportunities for promotion. Today the experts generally agree that important changes are taking place in the roles of men and women. Naturally, there are difficulties in adjusting to these changes.

单选题Very often, the human eye and brain can recognize familiar shapes even if all but a few significant points are left out. It is this creative power of the human eye and brain that may someday allow profoundly deaf people to talk in sign language over a special "telephone". Researchers have found that thirteen spots of light on each hand and one spot on the nose--to show head motion and provide a reference point for hand position--are sufficient for the performing of American Sign Language. The bright spots are produced by attaching pieces of a special tape to the nose, fingertips, and wrists and adjusting a closed-circuit television system so that only the bright spots appear on the screen of the receiver. After a few minutes of familiarization, pairs of deaf people are able to communicate freely over television. Deaf people and other sign readers can, of course, understand sign language on commercial television. But widespread link-ups of television systems for personal communication are economically impolite because a standard picture requires about one thousand times more information than a telephone circuit can carry. The researchers think if likely through the simplified picture of twenty-seven moving dots used in their experiments can be reduced to the capacity of a telephone line.

单选题Trees are useful to man in three very important ways: they supply him with wood and other products; they give him shade; and they help to prevent droughts and floods. 　　Unfortunately, in many parts of the world, man has not realized that the third of these service is the most important. In his eagerness to draw quick profit from the trees, he has cut them down is large numbers, only to find that without them he has lost the best friends he had. 2 000 years ago a rich and powerful country cut down its trees to build warships, with which to gain itself an empire. It gained the empire but, without its trees, its soil became hard and poor. When the empire fell to pieces, the home country found itself faced floods and starvation. 　　Even if a government realizes the importance of adequate supply of trees, it is difficult for it to persuade the villager to see this. The villager wants wood to cook his food with; and he can earn money by producing charcoal or selling wood to the townsman. He is usually too lazy or too careless to plant and take care of new trees. So, unless the government has a good control system, or can educate the people, the forests will slowly disappear. 　　This does not only mean that the villager’s sons and grandsons have fewer trees. The results are even more serious: for where there are trees their roots break the soil up ― allowing the rain to sink in ― and also bind the soil, thus preventing its being washed away easily; but where there are no trees, the rain falls on hard ground and flows away from the surface, causing floods and carrying away with it the rich topsoil ,in which crops grow so well. When all the top soil is gone, nothing remains but a useless desert.
