With its large urban population, China ranks first in the world inbic

6、ycle production and use. In fact, China is responsible for half of the worldsbike ownership, with 10 million bicycles found in Beijing alone. This amounts(5) to about one bicycle for every two residents, and makes cycling the most popularform of transportation in the capital.However, as economic pro

7、sperity has increased, individual car ownershiphas also risen. This shift has contributed to already serious problems with urbanpollution and traffic congestion. As a result, the government has encouraged even(10) more bicycle use. Bike lanes have been added to city streets, and more bicycleparking

8、lots have been created throughout Beijing. Still, critics point out that carsare much more convenient for many daily activities in a large city. Only time willtell if government measures will ensure that bicycles remain the favorite methodof transportation.（分数：2.00）(1).The author of the passage is p

12、tial part of life. For giraffes, two hours aLine day is enough. For bats, that number is closer to twenty. The average adult humanneeds between seven and nine hours of sleep every day. Despite these differences,mammals all have one thing in common: If they do not get enough sleep, they can(5) suffer

13、 serious mental and physical consequences.The most extensive sleep research has been conducted on people. Throughthese studies, scientists have identified two broad categories of sleep, which canbe further divided into five stages with distinct physiological functions. Takentogether, they form a com

14、plete sleep cycle. The first four stages are marked by a(30) lack of rapid eye movement (REM). Therefore, they are referred to as non-REMsleep. While people are engaged in non-REM sleep, several things are occurring.Researchers have discovered that during this early sleep, the human bodyreleases a s

15、eries of hormones responsible for the proper functioning of certainbody systems. Disrupted sleep can cause these hormones to fall out of balance.(15) The results can contribute to disorders such as diabetes, depression, infertility,or even cancer. Lack of sleep, especially in stages 3 and 4, can lit

16、erally stunt thegrowth of children and may increase rates of obesity in adults.Stage 5 sleep is defined by the occurrence of rapid eye movement, otherwiseknown as dreaming. Note that, while REM sleep is the final stage in a sleep cycle,(20) a complete cycle generally lasts only about 95 minutes. A p

17、erson will experiencefour to six cycles in one sleep session, with REM sleep taking up a larger portionof the cycle as the night continues. Scientists have advanced several theoriesabout why humans need REM sleep. One view is that dreaming aids in memoryconsolidation. Under this theory, during REM s

18、leep the brain not only strengthens(25) memory of important actions or events, but it weakens memory of unimportantthings. Another view is that dreaming is necessary for proper central nervoussystem development. Yet another theory suggests that REM sleep involves therepair of monoamine receptors. Th

19、e theories are not necessarily exclusive; in fact,they all reach the conclusion that REM sleep deprivation can result in death.（分数：4.00）(1).The author of the passage is primarily concerned with（分数：1.00）A.promoting mammalian sleep researchB.documenting the importance of non-REM sleep in hormone regul

20、ationC.describing the role of sleep in human behavior and developmentD.arguing that humans need more sleep to function optimallyE.(E) illustrating the importance of REM sleep to brain function(2).The author implies that disrupted sleep can cause disorders such as diabetes (line 15) because（分数：1.00）A

21、.diabetes is linked to obesityB.sufficient sleep is not crucial to good healthC.diabetes is a serious physical consequence of poor sleepD.the disorders are probably a result of unbalanced hormone productionE.(E) non-REM sleep is more important than REM sleep(3).The passage suggests that the author w

22、ould be most likely to agree with which of the following statements?（分数：1.00）A.A typical person needs more than six sleep cycles to maintain optimal health.B.REM sleep is more important than non-REM sleep.C.A typical person experiences more REM sleep at the end of the night.D.Lack of sleep can stunt

23、 the growth of adults.E.(E) The majority of sleep disorders occur in children.(4).The authors argument is developed primarily by the use of（分数：1.00）A.an attack on poorly constructed sleep research studiesB.a critique of recent scientific studies on REM-sleepC.a warning against getting too little sle

26、While forensic scientists commonly rely on fingerprints to help identify aLine person, it is not possible to use the same kind of technology with other speciesof mammals. Recently, however, a group of researchers from Tokyo developed adevice that allows them to identify individuals of the endangered

27、 Ganges River(5) dolphin species. This underwater acoustic device measures the clicking soundsproduced by the creatures and helps with identification and tracking, since eachsound is as completely unique as a fingerprint.Ganges River dolphins are rare in that, unlike the majority of theircounterpart

28、s, they live in rivers and lakes rather than oceans. The species is blind(10) and uses clicks to send out sonar pulses for guidance and to find food. In the pastfew decades, their numbers have decreased by 50 percent, because of fishing netentanglement, human predation, pollution, construction, or a

29、 combination ofthese factors. With this new acoustic technology, scientists hope to get a betteridea of how many of these dolphins still exist, as well as their migration patterns(15) and feeding habits. In turn, this information may help scientists protect andconserve this unique species.（分数：2.00）(

31、olphinB.suggest that, because of this blindness, the Ganges River dolphin survives only in rivers and lakesC.challenge the claim that the species decline in numbers is due to fishing net entanglement, human predation, pollution, or constructionD.refute the claim that the Ganges River dolphin can in

32、fact be identified and tracked by underwater acoustic devicesE.(E) lend credibility to the claim that the Ganges River dolphin is a rare species(2).The passage supplies information for answering which of the following questions?（分数：1.00）A.How do the remaining Ganges River dolphins still exist?B.What
