单选题5 Alison closed the door of her small flat and put down her briefcase. As usual, she had brought some work home from the travel agency. She wanted to have a quick bite to eat and then, after spending a few hours working, she was looking forward to watching television or listening to some music. She was just about to start preparing her dinner when there was a knock at the door. "Oh, no ! Who on earth could that be?" she muttered to herself. She went to the door and opened it just wide enough to see who it was. A man of about sixty was standing there. It took her a moment before she realized who he was. He lived in the flat below. They had passed each other on the stairs once or twice, and had nodded to each other but never really spoken. "Uh, sorry to bother you, but...uh...there's something I'd like to talk to you about," he mumbled. He had a long, thin face and two big front teeth that made him look rather like a rabbit. Alison hesitated, but then, opening the door wide, asked him to come in. It was then that she noticed the dog. She hated dogs—particularly big ones. This one was a very old, very fat bulldog. The man had already gone into her small living-room and, without being asked, had sat down on the sofa. The dog followed him in and climbed up on the sofa next to him, breathing heavily. She stared at it. It stared back. The man coughed. "Uh, do you mind if I smoke?" he asked. Before she could ask him not to, he had taken out a cigarette and lit it. "I'll tell you why I've come. I...I hope you won't be offended but, well..." he began and then stopped. Suddenly his face went red. His whole body began to shake. Then another cough exploded from somewhere deep inside him. Still coughing, he took out a grey, dirty-looking handkerchief and spat into it. Afterwards he put the cigarette back into his mouth and inhaled deeply. As he did so, some ash fell on the carpet. The man looked around the room. He seemed to have forgotten what he wanted to say. Alison glanced at her watch and wondered when he would get to the point. She waited. "Nice place you've got here," he said at last.

单选题{{B}}Passage 1{{/B}} Nowadays, with plentiful ice and electric churning, few people recall the shared excitement of the era when making ice cream was a rarely scheduled event. Then the iceman brought to the back door, on special order, a handsome 2-foot-square cube of cold crystal and everyone in the family {{B}}took a turn at the crank{{/B}}. The critical question among us children was, of course, who might lick the dasher. A century or so ago the novelist Stendhal knew only hand-churned ice cream and, when be first tasted it, ex-claimed, "What a pity this isn't a sin!" Hand-churning is still tops for perfectionists for no power-driven machine has yet been invented that can achieve a comparable texture. Even French Pot, the very best commercial method for making ice cream, calls for finishing by hand. Ice creams are based on carefully cooked well-chilled syrups and heavy custards, added to unwhipped cream. No form of vanilla flavoring can surpass that of vanilla suger or of the bean itself, steeped in a hot syrup. If sweetened frozen fruits are incorporated into the cream mixture instead of fresh fruits, be sure to adjust sugar content accordingly. Make up mixtures for chum-frozen ice creams the day before you freeze, to increasingly fill the container only 3/4 full to permit expansion. To pack the freezer, allow 3 to 6 quarts of chipped or cracked ice to I cup of coarse rock sail. Pack about 1/3 of the freezer with ice and add layers of salt and ice around the container until the freezer is full. Allow the pack to stand about 3 minutes before you start turning. Turn slowly at first, about 40 revolutions a minute, until a slight pull is felt. Them triple speed for 5 to 6 minutes. If any additions, such as finely cut candied or fresh fruits or nuts are to be made, do so at this point. Then repack and taper off the churning to a- bout 80 revolutions a minute for a few minutes more. The cream should be ready in 10 to 20 minutes, depending on the quality. If the ice cream or ice is to be used at once, it should be frozen harder then if you plan to serve it later. Should the interval be 2 hours or more, packing will firm it. To pack, pour off the salt water in the freezer and wipe off the lid. Remove the dasher carefully, making sure that no salt or water gets into the cream container Scrape the cream down from the sides of the container. Place a cork in the lid and replace the lid. Repack the container in the freezer with additional ice and salt, using the same proporions as before. Cover the freezer with newspapers, a piece of carpet or other heavy material. The cream should be smooth when served, If it proves granular, you used too much salt in the packing mixture, overfilled the inner, container with the ice cream mixture or turned too rapidly. If you are making a large quantity with the idea of storing some in the deep-freeze, package in sizes you plan on serving: Should ice cream be allowed to melt even slightly and is then refrozen, it loses in volume and even more in good texture.

单选题Passage Three The terrorist attacks in London Thursday served as a jarring reminder that in today's world, you never know what you might see when you pickup the newspaper or turn on the TV. Disturbing images of terror can trigger a visceral response no matter how close or far away from home the event happened. Throughout history, every military conflict has involved psychological warfare in one way or another as the enemy sought to break the morale of their opponent. But thanks to advances in technology, the popularity of the Internet, and proliferation of news coverage, the rules of engagement in this type of mental battle have changed. Whether it's a massive attack or a single horrific act, the effects of psychological warfare aren't limited to the physical damage inflicted. Instead, the goal of these attacks is to instill a sense of fear that is much greater than the actual threat itself. Therefore, the impact of psychological terror depends largely on how the acts are publicized and interpreted. But that also means there are ways to defend yourself and your loved ones by putting these fears into perspective and protecting your children from horrific images. What is psychological terror? "The use of terrorism as a tactic is predicated upon inducing a climate of fear that is incommensurate with the actual threat," says Middle Eastern historian Richard Bulliet of Columbia University. "Every time you have an act of violence. Publicizing that violence becomes an important part of the act itself." "There are various ways to have your impact. You can have your impact by the magnitude of what you do, by the symbolic character of target, or the horrific quality of what you do to a single person," Bulliet tells WebMD. "The point is that it isn't what you do, but it's how it's covered that determines the effect." For example, Bulliet says the Iranian hostage crisis, which began in 1979 and lasted for 444 days, was actually one of the most harmless things that happened in the Middle East in the last 25 years. All of the U.S. hostages were eventually released unharmed, but the event a psychological scar for many Americans who watched helplessly as each evening's newscast counted the days the hostages were being held captive. Bulliet says terrorists frequently exploit images of a group of masked individuals exerting total power over their captives to send the message that the act is a collective demonstration of the group's power rather than an individual criminal act. "You don't have the notion that a certain person has taken a hostage. 'It's an image of group power, and the force becomes generalized rather than personalized," says Bulliet. "The randomness and the ubiquity of the threat give the impression of vastly greater capacities." Psychiatrist Ansar Haroun, who served in the U.S. Army Reserves in the first Gulf War and more recently in Afghanistan, says that terrorist groups often resort to psychological warfare because it's the only tactic they have available to them. "They don't have M-16s, and we have M-16s, they don't have the mighty military power that we have, and they only have access to things like kidnapping," says Haroun, who is also a clinical professor of psychiatry at the University of California, San Diego. "In psychological warfare, even one beheading can have the psychological impact that might be associated with killing 1,0000 of the enemy," Haroun tells WebMD. "You haven't really harmed the enemy very much by killing one person on the other side, but in terms of inspiring fear, anxiety, terror, and making us all feel bad, you've achieved a lot of demoralization.
