17、At the end of each passage, you will hear some questions. Both the passage and the questions will be spoken only once. After you hear a question, you must choose the best answer from the four choices marked A, B, C and D. 1 【听力原文】 Have you ever dashed across a parking lot in a sudden rainstorm? You
18、might think that youll stay drier by running as fast as you can. But in fact, the faster you run, the more drops youll run into horizontally, soaking your front. You want to stay as dry as possible, so what should you do: walk or run? A scientist would break this problem into its simplest elements.
19、If theres no wind, youll only get wet from two directions above as the drops fall on you, and in front as you move into them.The amount of wetness from above is determined by how long you stay in the rain. If you stay outside twice as long, your head and shoulders will get twice as wet. As far as yo
20、ur top is concerned, the faster you run, the better. Running faster means less time spent in the rain. The water you run into is another story. The faster you go, the more rapidly your front will collide with raindrops, but youll also spend less time running through them. As it turns out, no matter
21、how fast you go, youll always hit the same number of drops from the front. If you slow down, youll hit them more slowly, but the total amount will be the same at the end of your trip. Putting the two parts together, top and front, its clear that running will indeed keep you drier than walking, but n
22、ot by very much. It only keeps the top of your head and shoulders drier. Your front will be just as wet no matter how fast you run. 5.What decides the amount of drops that soak your front? 6. Which factor determines the amount of wetness from above? 7.What will happen to your front if you go faster

The answer is yes, but how fish drink water depends on where they live. Water gets into a fishs body through a process in which water diffuses from a higher to a lower
24、 concentration. For example, if there is more water outside of a cell than inside, water will try to flow into the cell until there is the same concentration of water both outside and inside. The body of a fish acts the same way, either absorbing or losing water depending on its surroundings.Whether
25、 a fish absorbs or loses water is based on the fact that all fish must maintain a certain amount of salt in their bodies to stay healthy. Fish that live in fresh water have a higher concentration of salt in their bodies than the surrounding water. Consequently, water continuously flows into the fish
26、s body to attempt to dilute the amount of salt in the fish until it is equal to the amount of salt in the surrounding water. Since fish cannot allow their salt content to be diminished, their kidneys work overtime to expel excess water. Ocean fish have the opposite problem. Surrounded by salt water,
27、 their bodies contain a relatively lower concentration of salt than the ocean water. In this case it causes the fish to constantly lose water in order to equalize salt concentration inside and outside the body to partly compensate for the water loss, ocean fish actually drink water through their mou

And to get rid of the excess salt they take in by drinking seawater, they also get some salt off their body. 8.What does the speaker say determines how fish drink water? 9.What do fish do to stay healthy? 10.Why do fish in fresh water make their kidneys work overtime? 4 【正确答案】 B 【知识模块】 听力短文 5 【

But most bees are non-aggressive, and only sting when provoked. In fact, once you get beyond the stinger, bees are pretty fascinating.
30、For example, honeybees are great builders. Beehive construction begins with finding a suitable site.Scout bees seek hollow spaces in trees and human-made structures. Such spaces must be able to hold at least six and a half gallons, and have a small entrance that faces south for warmth. Once theyve f
31、ound the perfect spot, the scouts prepare the site by clearing away loose wood or other rubbish and coat the space. Worker bees then take over, using their wax to build the hive. Starting from the top and working down, they bald combs-layers of cells with passageways along the walls to allow bees to
32、 move between combs. Each layer of cells has a specialized purpose.The most important cells store honey. The bottom layers are designated for infant-rearing. Just beneath are brood cells where baby, bees become worker bees, and off to the side are cells housing baby bees. Last, but certainly not lea
33、st, special cells are set aside,to shelter infant queen bees. A typical nest has about 100, 000 cells with a total surface area of about twenty-seven square feet. Most of the cells are used to store the more than forty pounds of honey required to feed a bee colony during the winter. They may not win

35、earth gets hotter in the new century, what will happen to animals and the plants which animals depend on for survival? The question offers another way of looking at the greenhouse effect. People have talked about the general problem of global warming for some time. Global warming, a recent warming o
36、f the Earths surface and lower atmosphere, is believed to be the result of a strengthening of the greenhouse effect. Because of this, people were usually worried about things like whether to buy a home on the coast. Biologists and other scientists turned their attention to plants and animals at an i
37、mportant meeting. They reviewed evidence that plants and animals are sensitive to climate.Since the Ice Age ended 2,000 years ago, and warmer temperatures returned to the northern latitudes, many species have migrated north. If the predictions about the greenhouse are correct, temperatures will rise
38、 by the same amount in the next 100 years as they did in the past 10,000. Will animals and plants be a-ble to adapt that quickly to change in the environment? Many wont. Certain species will probably become very rare. Experts say plants under climate stress will very open to disease and fire. Forest
39、 fires may become more common. That in turn may harm animals that depend on the trees for food or shelter. Any preserves we set up to protect the endangered species may become useless as the species are forced to migrate along with their natural homes. Changes are part of life, but rapid change, say

41、 【知识模块】 听力短文 13 【听力原文】 Point at a ball and a dog will look at the ball, whereas a cat will probably look at your hand. Dogs seem to have a ready understanding of how human beings direct attention by pointing, and can follow our gestures almost as if they thought the same way we do. Of course, dogs p
42、robably arent born knowing anything about people. We just carefully train them to look, fetch, and so on. An expert at the Max Plank Institute in Germany, named Michael Tomasello ran a series of tests on dogs, in which they had to find which sealed container had yummy dog food in it. The only hint t
43、hey got was from a human being who looked at or pointed at the right container. This wasnt hard for dogs at all. But it was hard for wolves. Wolves that have been raised by people should have had the same success at finding the sealed container, but they didnt. Even monkeys, which are very smart ani
44、mals indeed, werent as fast at finding the food as dogs. What does this mean? One interpretation is that dogs do have a natural ability to understand forms of human communication. Even nine-week old puppies found the food, suggesting the skill is there before training. Wolves dont have the skill, su
45、ggesting that it has developed in dogs since the time they branched off from their predecessors. There is debate about this idea.But Tomasello thinks that in the past fifteen thousand years, as human beings and dogs have evolved together, the basis for dogs ability to understand what you mean may ha

47、ears, if you suffered through music lessons as a kid you may have benefited from those lessons in ways you wouldnt expect. When you are trained on a musical instrument your brain is stimulated and changes and develops as a result. Because the parts of the brain are connected to one another, this sti
48、mulation doesnt affect musical ability only.Experts have discovered that the stimulation musical training enacts on the left part of your brain which enhances verbal memo-ry.People with musical training are significantly better at retailing words from a list as well as better learning new words. Wha
49、ts more, the longer the duration of musical training is, the better the verbal memory is. So children who have studied music for two years demonstrate better verbal memory than children who have not studied music, children who continue to study music keep improving their verbal memory all the time. The good news for those of us who were trained on musical instruments but quit at some point is that we dont seem to lose the verbal benefits we gain from this training. Scientists are particularly interested in what this suggests and thus the predictab
