单选题 Passage 8 Excitement, fatigue, and anxiety can all be detected from someone's blinks, according to psychologist John Stern {{U}}(1) {{/U}} Washington University in St. Louis. Stern specialized in the study on these tiny twitches, using them as sensitive {{U}}(2) {{/U}} of how the brain works. "I use blinks as a psychological measure to make {{U}}(3) {{/U}} about thinking because I have very little {{U}}(4) {{/U}} in what you tell me about what you ,are thinking." He says. "If I ask you the question, 'what does the phrase a rolling stone gathers no moss mean?' you can't tell me {{U}}(5) {{/U}} you've started looking for the answer. But I can, by watching your eyes." Blinks also tell Stem when you have understood his question--often long before he's finished asking it--and when you've found an answer or part of {{U}}(6) {{/U}}. "We blink at times {{U}}(7) {{/U}} are psychologically important." He says. "You have listened to a question, you understand it, {{U}}(8) {{/U}} you can take time out for a blink. Blinks are {{U}}(9) {{/U}} marks. Their timing is tied to what is going on in your {{U}}(10) {{/U}}." Stem has found that {{U}}(11) {{/U}} suppress blinks when they are absorbing or anticipating {{U}}(12) {{/U}} but not when they're reciting it. People blink later, for example, {{U}}(13) {{/U}} they have to memorize six numbers instead of two. "You don't blink," he says, "until you have {{U}}(14) {{/U}} the information to some short-term memory store." And if subjects are cued {{U}}(15) {{/U}} the set of numbers is coming, say, five seconds, they'll curb their blinks until the task is {{U}}(16) {{/U}} Similarly, the more important the information that people are taking in, the more likely they are to put their blinks on hold for {{U}}(17) {{/U}}. Pilots blink less when they're {{U}}(18) {{/U}} for flying a plane than when they {{U}}(19) {{/U}} their eyes from the road to the rearview mirror. But if they see the flashing lights of a state trooper behind them, their {{U}}(20) {{/U}} will move fast unmoistened to the speedometer and back to the mirror.

单选题Questions 11-15 are based on the following passage: Although no one is certain why migration occurs, there are several theories. One theory claims that prehistoric birds of the Northern Hemisphere were forced south during the Ice Age. As the glaciers melted, the birds came back to their homelands, spent the summer, and then went south again as the ice advanced in winter. In time, the migration became a habit in spite of the disappearance of glaciers. Another theory proposes that the ancestral home of all modern birds was the tropics. When the region became overpopulated, many species were crowded north. During the summer, there was plenty of food, but during the winter, scarcity forced them to return to the tropics. A more recent theory suggests a relationship between increasing daylight and the stimulation of certain glands (腺) in the birds' bodies that may prepare them for migration. One scientist has been able to cause midwinter migrations by exposing birds to artificial periods of daylight. He has concluded that changes occur in the bodies of birds due to seasonal changes in the length of daylight.

单选题 Lazy? Shy? Live in a cave? Those might not be positive attributes for the average human, but they sure are good for animals trying to survive in a changing environment. According to a new study, beasts that hibernate(冬眠)or crawl into holes are less likely to be listed as endangered than those that don't. Following up a previous study on extinct animals, which showed that species exhibiting "sleep or hide" (SLOH)behaviors did better than others, the researchers wanted to see if the same was true of modern crearures like moles and bears. To find out if our more timid animals have a leg up in the survival game, researchers made a master list of 443 sleep-or-hide mammals. With their list in hand, the team compared their 443 to the "red list" of endangered species published by the International Union for Conservation of Nature. As suspected, a sleepy of hiding animal was less likely to be on the red list than a regular animal, and a red-list animal was also less likely to be a SLOH-er. This makes a lot of sense, as animals that hide away in a cave or a tree hole are protected by their physical shelters from a variable environment outside, while hibernators enjoy a flexible metabolism(新陈代谢)that can help them adapt to a changing climate.
