6、_四、BPart Reading (总题数:3,分数:15.00)BPassage 1/BStudies of whales in captivity (囚禁;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 l
7、ed some scientists to believe that whales possess a high level of intelligence.The 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,
8、 a sperm whales brain is only about 0.02 percent of its body weight, while a human 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
9、 folding of the upper surface of the brain. This folding increases the surface area 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
10、most interesting indications of whale intelligence came with the discovery in the 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 m
11、ay be simply longer versions of the mating songs also noted in birds and amphibians (两栖动物).(分数:5.00)(1).The best title for this passage would be _ .(分数:1.00)A.Studies of Whales in CaptivityB.Whales Physiology and Social BehaviorC.Study of Whales IntelligenceD.Whale(2).Which of the following does not
12、 illustrate the intelligence about whale?(分数:1.00)A.Their learning and problem-solving skills, together with their curiosity and often eager interactions with humans.B.The large brains of whales.C.Complex behavior.D.Relying on hearing.(3).If a sperm whales weight is thirty tons, the size of a human
13、will be _ kilogram.(分数:1.00)A.210B.125C.100D.75(4).The sperm whales visual centers 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
14、.complex behavior may reveal more about whale intelligence than brain sizeD.this 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.f
15、irmB.obviousC.reliableD.liableBPassage 2/BPlacing a satellite into 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 li
16、fts the entire launch vehicle-with its load of fuel, the rocket body, 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
17、 second stage then ignites, providing the energy necessary to lift 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
18、final orbital altitude. After the satellite has reached the final 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 199
19、0 the United States began launching some satellites from aircraft 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
20、size of the rocket is limited by the size and strength of the aircraft, 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
21、.(2).According to the second paragraph, which of the following is 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.Af
22、ter its engines use up its fuel, the first stage part of the rocket 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
23、necessary to lift the satellite into orbit.“, “ignites“ means _ .(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 St
