6、被拘留的状态) have taught us much about their physiology (生理学) as well as their complex social behavior. Their learning and problem-solving skills, together with their curiosity and often eager interactions with humans, have led some scientists to believe that whales possess a high level of intelligence.T
7、he large brains of whales also suggest a high intelligence. The sperm whale (抹香鲸)s brain is considerably larger than an elephants, brain and six times the size of a human brain. However, relative to the rest of the body, a sperm whales brain is only about 0.02 percent of its body weight, while a hum
8、an brain is about 2 percent. These animals tend to rely on hearing more than vision, which explains why the visual centers of their brains are smaller proportionally than those in humans. Another feature is the degree of folding of the upper surface of the brain. This folding increases the surface a
9、rea and has been observed in more intelligent animals. Whale brains generally show as much or more folding area as is seen in humans.Complex behavior may reveal more about whale intelligence than brain size. Perhaps the most interesting indications of whale intelligence came with the discovery in th
10、e 1970s of whale singing. Singing is most common on the winter mating grounds, for example in the Caribbean and Hawaii.There is no solid evidence that the songs encode language in an intellectual sense. The whale songs may be simply longer versions of the mating songs also noted in birds and amphibi

13、rs of their brains are smaller proportionally than those in humans, this can explain why _ .(分数:1.00)A.their eyesight is better than hearingB.whale brains generally show as much or more folding area as is seen in humansC.complex behavior may reveal more about whale intelligence than brain sizeD.this
14、 folding increases the surface area and has been observed in more intelligent animals(5).“There is no solid evidence that the songs encode language in an intellectual sense.“ in the sentence “solid“ means _ .(分数:1.00)A.firmB.obviousC.reliableD.liable八、Passage 2(总题数:1,分数:5.00)Placing a satellite into
15、 orbit requires a tremendous amount of energy, which is achieved from multistage rockets burning chemical fuels. The first stage of a multistage rocket consists of rocket engines that provide a huge amount of force. The first stage lifts the entire launch vehicle-with its load of fuel, the rocket bo
16、dy, and the satellite-off the launch pad (发射台) and into the first part of the flight. After its engines use all their fuel, the first stage portion of the rocket separates from the rest of the launch vehicle and falls to the earth.The second stage then ignites, providing the energy necessary to lift
17、 the satellite into orbit. It, too, then separates from the satellite and any remaining rocket stages.The rest of the launch depends on the satellites mission. And a third rocket stage provides the energy to lift the satellite to its final orbital altitude. After the satellite has reached the final
18、altitude, another rocket engine fires and gives the satellite a circular orbit. All rocket-engine burns occur at a precise moment and last for a precise amount of time so that the satellite achieves its proper position in space.In 1990 the United States began launching some satellites from aircraft
19、flying at high altitudes. This method still requires a rocket-powered launch vehicle, but because the vehicle does not have to overcome friction with the thick atmosphere found at low altitudes, much less fuel is needed. However, the size of the rocket is limited by the size and strength of the airc
20、raft, so only smaller satellites can be launched this way.(分数:5.00)(1).What is the main idea about the passage?(分数:1.00)A.Placing a satellite into orbit.B.Multistage rockets.C.Launching some satellites from aircraft.D.Rocket launching.(2).According to the second paragraph, which of the following is
21、NOT true?(分数:1.00)A.The first stage of a multistage rocket consists of rocket engines that provide a large amount of force.B.The first stage lifts the entire launch vehicle off the launch pad and into the first part of the flight.C.After its engines use up its fuel, the first stage part of the rocke
22、t separates from the rest of the launch vehicle and falls to the space.D.The entire launch vehicle includes its load of fuel, the rocket body, and the satellite.(3).In the sentence “The second stage then ignites, providing the energy necessary to lift the satellite into orbit.“, “ignites“ means _ .(
23、分数:1.00)A.startsB.blasts offC.departsD.fires(4).Generally speaking how many stages are there in a multistage rocket?(分数:1.00)A.Two.B.Three.C.Four.D.Five.(5).Which of the following statements is NOT the characteristics of the United States aircraft launching some satellites?(分数:1.00)A.This method sti
24、ll needs a rocket-powered launch vehicle.B.The vehicle can pay no attention to friction with the thick atmosphere.C.Much more fuel is needed.D.Only smaller satellites can be launched this way.九、Passage 3(总题数:1,分数:5.00)In earlier centuries, nursing care was usually provided by volunteers who had litt
