单选题Most of us can't remember our first vaccination, a common practice of preventing us against diseases. Chances are, it was a shot filled with a drug formula—just enough to produce a mild infection but not the full-blown disease. Immunizing, or preventing people against some diseases in this way has worked reasonably well for more than a century, but scientists think they can do better by using genetically engineered plants. We all know that eating fruits and vegetables is good for us, but within the next decade we could be eating as a way to deliver drugs that keeps off epidemic diseases or that treat various chronic conditions. "The idea of vaccinating people with edible plants is very new," says Dwayne Kirk of the Boyce Thompson Institute for Plant Research in Ithaca, New York, "But it's a lot friendlier than injections." Potatoes and tomatoes seem for now to be the most efficient vehicles for the new approach. Instead of mixing viral or bacterial DNA in a formula for injection, for example, scientists could insert it into soil bacteria. When the bacteria are taken-up by the plant, the DNA material gets into the plant. Another method of getting genes into plants is to coat tiny particles of metals such as gold with foreign DNA, then shoot the particles directly into plant cells. Either way, the plant's cells start to produce whatever proteins the new genes are designed to make. Immunization begins when the plant or its fruit is eaten, prompting the body to produce the appropriate antibodies. The technique does not have to be limited to infectious diseases, however. It may even be useful for conditions such as Type I diabetes. For such patients, eating genetically engineered plants could eventually train the body's defenses, all without the bother—or risk—of a needle. Plant-based vaccines are particularly attractive for Third World countries, where storage and distribution of drugs are a problem. Eventually, people in these areas may inoculate themselves against diseases simply by growing a crop of genetically engineered fruits or vegetables and eating a few several times a year.

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 modern 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What's the woman's occupation?

单选题Whitney's is a restaurant and a gambling place. There is no restaurant or hotel in France, Italy, Germany, or Spain whose food can compare with Whitney's. At Whitney's there are no menus; you order what you wish from an endless variety of special foods. But on your first visit to Whitney's you often pay little attention to what you eat, for very soon, as the room begins to fill, you can hardly believe your eyes. At every table you soon recognize someone who is famous. After lunch this well-dressed group of persons goes down to the gambling room. By two o'clock the room is well filled, by three it is crowded, and it remains so until the early hours of the morning. I was deeply impressed, and I welcomed an opportunity to meet Mr. Whitney himself. I found him a man square of jaw, cold of eyes, his face rather unexpressive — much what I expected. He was not a very communicative person. He told me his once experience, though. "The other day a lady, who claimed herself Mrs. John Rossiter, came to my once." He said, "Before she said a word she began to cry; the tears came into her eyes and began to run down her cheeks, and she kept wiping them away with her handkerchief, trying all the way to control herself. I can't stand, but this rather impressed me." "Her husband had lost thirty thousand dollars in the gambling room, she told me. I have known John Rossiter well enough to say 'Hello,' but not much more than that. Mrs. Rossiter explained that the great problem of her life had been her husband's gambling. It was a long story, I don't remember the details, but I told her that I agreed to give her back the money which her husband had lost." As he spoke of this a light came into his eyes, and a faint smile appeared on his lips. "The next morning I met John Rossiter. I asked him not to come here after his wife told me about his troubles. But he said he was not married./
