1、Keeping Cut Flowers1 While everybody enjoys fresh cut flowers around his house, few people know how to keep them foras long as possible. This may be done by keeping in mind a few simple fact. 2 An important thing to remember about cut flowers is that they are sensitive to temperature. Forexample, studies have shown that cut carnations (康乃馨) retain their freshness eight times longer when kept at 12℃ than when kept at 26℃. Keeping freshly harvested flowers at the right temperatures is probably the most important aspect of flower care. 3 Flowers are not intended by nature to live very long. Their biological purpose is simply to attract birds orinsects, such as bees, forpollination (粉). After that, they quickly dry up and die. The process by which flowers consume oxygen and produce carbon dioxide, called respiration, generates the energy the flower needs to give the flower its shape and color. The making of seeds also depends on this energy. While all giving things respire, flowers have a high level of respiration. A result of all this respiration is heat, and forflowers the level of heat relative to the mass of the flower is very high. Respiration also brings about the eventual death of the flower. Thus the greater the level of respiration, the sooner the flower dies. 4 How, then, to control the rate at which flowers die? By controlling respiration. How is respiration controlled? By controlling temperature. We know that respiration produces heat, but the reverse is also true. Thus by maintaining low temperatures, respiration is reduced and the cut flower will age more slowly. 5 Another vital factorin keeping cut flowers is the quality of the water in which they are placed. Flowers find it difficult to "drink" water that is dirty orotherwise polluted. Even when water looks and smells clean, it almost certainly contains harmful substances that can endanger the flowers. To rid the water of these unwanted substances, household chlorine bleach (含氯漂白剂) can be used in small quantities. It is recommended that 15 drops of chlorine bleach (at 4% solution) be added to each liter of water. The water and solution should also be replaced each day. Paragraph 3____【单选题】

3、Sharing SilenceDeaf teenagers Orlando Chavez and German Resendiz have been friends since kindergarten (幼儿园). Together the two boys, who go to Escondido High School in California, have had the difficult job of learning in schools where the majority of the students can speak and hear.Orlando lost his hearing at the age of one. German was born deaf, and his parents moved from Mexico to find a school where he could learn sign language. He met Orlando on their first day of kinder garten."We were in a special class with about 25 other deaf kids," German remembered. "Before then, I didn\'t know I was deaf and I was different.""Being young and deaf in regular classes was very hard," signs Orlando. "The other kids didn\'t understand us and we didn\'t understand them. But we\'ve all grown up together, and today, I\'m popular because I\'m deaf. Kids try to communicate with me."Some things are very difficult forthe two boys. "We can\'t talk on the phone, so if we need help, we can\'t call an emergency service," German signs.

4、Why Would They Falsely Confess?Why on earth would an innocent person falsely confess to committing a crime? To most people, it just doesn\'t seem logical. But it is logical, say experts, if you understand what can happen in a police interrogation room.Under the right conditions, people\'s minds are susceptible to influence, and the pressure put on suspects during police grilling is enormous. "It\'s a little like somebody\'s working on them with a dental drill," says Franklin Zimring, a law professorat the University of California at Berkeley. "The pressure is important to understand, because otherwise it\'s impossible to understand why someone would say he did something he didn\'t do. The answer is: to put an end to an uncomfortable situation that will continue until he does confess."Developmental psychologist Allison Redlich recently conducted a laboratory study to determine how likely people are to confess to things they didn\'t do. ______ The researchers then intentionally crashed the computers and accused the participants of hitting the "alt" key to see if they would sign a statement falsely taking responsibility.Redlich\'s findings clearly demonstrate how easy it can be to get people to falsely confess: 59 percent of the young adults in the experiment immediately confessed. Redlich also found that the younger the participant, the more likely a false confession. Of the 15-to 16-year-olds, 72 percent signed confessions, as did 78 percent of the 12-to 13-year-olds."There\'s no question that young people are more at risk," says Saul Kassin, a psychology professorat Williams College, who has done similar studies with similar results, "But adults are highly vulnerable too."Both Kassin and Redlich note that the entire "interrogation" in their experiments consisted of a simple accusation-not hours of aggressive questioning-and still, most participants falsely confessed.Because of the stress of a police interrogation, they conclude, suspects can become convinced that falsely confessing is the easiest way out of a bad situation. "In some ways," says Kassin, "false confession becomes a rational decision."【单选题】
A.In her experiment, participants were seated at computers and told not to hit the "alt" key, because doing so would crash the systems.
B."In some ways," says Kassin, "false confession becomes a rational decision."
C."It\'s a little like somebody\'s working on them with a dental drill," says Franklin Zimring, a law professorat the University of California at Berkeley.
D."But adults are highly vulnerable too."
E.How could an innocent person admit to doing something he didn\'t do?
F.Redlich also found that the younger the participant, the more likely a false confession.
正确答案:A
答案解析:本段提到一个心理学家做了一个实验(a laboratory study),也提到了crashed the computers和the "alt" key,这些都和选项A对应了起来。这是补全文章的重要策略,即文章和选项的对应关系。
