2、 Chinese:1. 代沟的表现。2. 代沟出现的家庭原因。3. 代沟出现的社会原因。Generation GapPart Reading Comprehension(Skimming and Scanning) (15 minutes)Directions: In this part, you will have 15 minutes to go over the passage quickly and answer the questions on Answer Sheet 1. For questions 1-7, choose the best answer from the fou
3、r choices marked A), B), C) and D). For question 8-10, complete the sentences with the information given in the passage.Animals on the MoveIt looked like a scene from “Jaws” but without the dramatic music. A huge shark was lowly swimming through the water, its tail swinging back and forth like the p
4、endulum of a clock.Suddenly sensitive nerve ending in the sharks skin picked up vibrations of a struggling fish. The shark was immediately transformed into a deadly, efficient machine of death. With muscles taut, the shark knifed through the water at a rapid speed. In a flash the shark caught its vi
5、ctim, a large fish, in its powerful jaws. Then, jerking its head back and forth, the shark tore huge chunks of flesh from its victim and swallowed them. Soon the action was over.Moving to SurviveIn pursuing its prey, the shark demonstrated in a dramatic way the important role of movement, or locomot
6、ion, in animals.Like the shark, most animals use movement to find food. They also use locomotion to escape enemies, find a mate, and explore new territories. The methods of locomotion include crawling, hopping, slithering, flying, swimming, or walking.Humans have the added advantage of using their v
7、arious inventions to move about in just about any kind of environment. Automobiles, rockets, and submarines transport humans from deep oceans to as far away as the moon. However, for other animals movement came about naturally through millions of years of evolution. One of the most successful exampl
8、es of animal locomotion is that of the shark. Its ability to quickly zero in on its prey has always impressed scientists. But it took a detailed study by Duke University marine biologists S. A. Wainwright, F. Vosburgh, and J. H. Hebrank to find out how the sharks did it. In their study the scientist
9、s observed sharks swimming in a tank at Marine land in Saint Augustine, Fla. Movies were taken of the sharks movements and analyzed. Studies were also made of shark skin and muscle.Skin Is the KeyThe biologists discovered that the skin of the shark is the key to the animals high efficiency in swimmi
10、ng through the water. The skin contains many fibers that crisscross like the inside of a belted radial tire. The fibers are called collagen fibers. These fibers can either store or release large amounts of energy depending on whether the fibers are relaxed or taut. When the fibers are stretched, ene
11、rgy is stored in them the way energy is stored in the string of a bow when pulled tight. When the energy is released, the fibers become relaxed.The Duke University biologists have found that the greatest stretching occurs where the shark bends its body while swimming. During the bodys back and forth
12、 motion, fibers along the outside part of the bending body stretch greatly. Much potential energy is stored in the fibers. This energy is released when the sharks body snaps back the other way.As energy is alternately stored and released on both sides of the animals body, the tail whips strongly bac
13、k and forth. This whip-like action propels the animal through the water like a living bullet.Source of EnergyWhat causes the fibers to store so much energy? In finding the answer the Duke University scientists learned that the sharks similarity to a belted radial tire doesnt stop with the skin. Just
14、 as a radial tire is inflated by pressure, so, too, is the area just under the sharks collagen “radials”. Instead of air pressure, however, the pressure in the shark may be due to the force of the blood pressing on the collagen fibers.When the shark swims slowly, the pressure on the fibers is relati
15、vely low. The fibers are more relaxed, and the shark is able to bend its body at sharp angles. The animal swims this way when looking around for food or just swimming. However, when the shark detects an important food source, some fantastic involuntary changes take place.The pressure inside the anim
16、al may increase by 10 times. This pressure change greatly stretches the fibers, enabling much energy to be stored.This energy is then transferred to the tail, and the shark is off. The rest of the story is predictable.Dolphin Has Speed RecordAnother fast marine animal is the dolphin. This seagoing m
17、ammal has been clocked at speeds of 32 kilometers (20 miles) an hour. Biologists studying the dolphin have discovered that, like the shark, the animals efficient locomotion can be traced to its skin. A dolphins skin is made up in such a way that it offers very little resistance to the water flowing
18、over it. Normally when a fish or other object moves slowly through the water, the water flows smoothly past the body. This smooth flow is known as laminar flow. However, at faster speeds the water becomes more turbulent along the moving fish. This turbulence muses friction and slows the fish down.In
19、 a dolphin the skin is so flexible that it bends and yields to the waviness of the water.The waves, in effect, become tucked into the skins folds. This allows the rest of the water to move smoothly by in a laminar flow. Where other animals would be slowed by turbulent water at rapid speeds, the dolp
20、hin can race through the water at record breaking speeds.Other Animals Less EfficientNot all animals move as efficiently as sharks and dolphins. Perhaps the greatest loser in locomotion efficiency is the slug. The slug, which looks like a snail without a shell, lays down a slimy trail over which it
21、crawls. It uses so much energy producing the slimy mucus and crawling over it that a mouse traveling the same distance uses only one twelfth as much energy.Scientists say that because of the slugs inefficient use of energy, its lifestyle must be restricted. That is, the animals are forced to confine
22、 themselves to small areas for obtaining food and finding proper living conditions. Have humans ever been faced with this kind of problem?1.According to the passage, a shark can use movement to do something except .A )to find foodB) to avoid being chased by its enemiesC) to find a new place to liveD
23、) to show its braveness2.Examples of automobiles, rockets and submarines are used to show that .A)humans are the most clever living creatures in the worldB)human inventions enable us to travel in almost any kind of environmentC)humans are very successful in inventing transportation toolsD)humans can

D)The jaw.4.According to the Duke University scientists, when does the shark stretch its collagen fibers to the greatest extent?A)When moving its tail rapidly
25、.B)When finding its preys.C)When staying without any movement.D)When bending its body in swimming.5.Why is the area just under the sharks collagen fibers similar to a belted radial tire?A)Because it is also full of blood pressure.B)Because it is also filled of air pressure.C)Because it is also infla
26、ted by pressure.D)Because it also can be used again and again.6.A laminar flow is formed when a fish swims .A)slowly through the waterB)rapidly through the waterC)against the currentD)at the fastest speed in water7.Consuming the equal amount of energy as a slug does, a mouse can travelas long as it.
