City elders across the United States are campaigning (呼吁) to restrict their numbers, while the Hong Kong government is proposing to license (批准) their operation.

According to one estimated, each establishment can make between $250 and $1,500 a day. The schoolchildren in uniforms there are not allowed into these centers.

Now kids and adults alike play these games in the privacy of their homes. Video game sets have invaded (进入) most homes. The question that must be asked is: Have they any education value?

单选题The most popular strokes system is the "Five- stroke Coding System". The principle of this system is to break down each Chinese character into different strokes, and each key in the keyboard represents one stroke. Anyone not knowing the pronunciation may type the character by hitting the keys representing different strokes. This system is very efficient but it needs some training before one could really type Chinese at a high speed.

单选题 All of us communicate with one another verbally (口头的) as well as non-verbally. Most of thetime we are not aware that we're doing it. We wave a hand, meet someone else's eyes or lookaway, shift positions in a chair. We make these movements unconsciously. But researchers havediscovered that there is a system to them almost as consistent (一致的) and comprehensible aslanguage. Every culture has its body language. The way an Englishman crosses his legs is nothing likethe way a male American does it. In talking, Americans are likely to end a statement with a lowering of the eyelids. They conclude a question with a lift of the hand or a widening of theeyes. With a future-tense verb they often gesture with a forward movement. There are regionalidioms too. Your sex, ethnic background, social class and personal style all influence your bodylanguage. Nevertheless, you move and gesture within a certain idiom. Usually, the wordless communication acts to qualify the words. What the non-verbal elements express very often, and very efficiently, is the emotional side of the message. When a personfeels liked or disliked, often it's a case of "not what he said but the way he said it." Experts in the study of communication through body movement are not prepared to spell outa precise vocabulary of gestures. When an American rubs his nose, it may mean he is disagreeingwith someone or rejecting something. But there are other possible interpretations, too. The expertlooks for patterns in the context, not for an isolated meaningful gesture.

单选题Genes that control factors such as size, color and shape determine the differences in fruit. And now that scientists have discovered how to detect different genes, farmers can hand over a young and tender branch to have its genes checked prior to planting. It works the same way as a detective (侦探) checking finger-prints. Once farmers know which trees are good and which are bad, they can discard the bad ones. Farmers can even create new varieties according to their individual tastes. In the past three years, tens of thousands of tests were carried out to determine the genetic (基因的) features of fruit. Zhang, a Chinese scientists, showed a photo of a DNA (脱氧核糖核酸)-test and pointed to the shining lines on it, saying that the lines were genetic signs that tell us what a tree's fruit will be like. For example, the ordinary pear tree bears fruit after four years. But now it only takes a month to test the DNA from a young leaf and a farmer will know everything about its fruit. By mixing different types of trees with suitable genes, farmers can create whatever fruit trees they want.

单选题Task 2 In Washington D.C., 1600 Pennsylvania Avenue is a very special address. It is the address of the White House, the home of the president of the United States. Originally the White House was gray and was called the Presidential Palace. It was built from 1792 to 1800. At this time, the city of Washington itself was being built. It was to be the nation's new capital city. George Washington, the first president, and Pierre Charles 12Enfant, a French engineer, chose the place for the new city. L'Enfant then planned the city. The president's home was an important part of the plan. A contest was held to pick a design for the president's home. An architect named James Hobart won. He designed a large three-story house of gray stone. President Washington never lived in the Presidential Palace. The first president to live there was John Adams, the second president of the United States, and his wife Mrs. Adams did not really like her new house. In her letters, she often complained about the cold. Fifty fireplaces were not enough to keep the house warm! In 1812 the United States and Britain went to war. In 1814 the British invaded Washington. They burned many buildings, including the Presidential Palace. After the war James Hoban, the original architect, partially rebuilt the president's home. To cover the marks of the fire, the building was painted white. Before long it became known as the White House. The White House is one of the most popular tourist attractions in the United States. Every year more than 1.5 million visitors go through the five rooms that are open to the public.
