The cartoon series enjoyed by young and oldalike revolved

8、mostly around the misadventures of this loveable bear and hissidekick Boo-Boo as they attempted to snag “pic-a-nic“ baskets in the made-up(5) land of Jellystone Park. Its not often that people think about where the ideas forthese cartoon characters came from, which brings up an interesting point: Do

9、bears actually search for food left in picnic baskets and unattended campsites?Anyone who has watched an episode of the classic cartoon can see that the bearsbehavior goes far beyond the limits of what is natural. The thing that must be(10) explored, then, is which of those humorous antics were imag

10、ined by the writersat Hanna-Barbera, and which were actually based on a bears normal behaviors.Remarkably enough, bears have been known to seek out food from someunlikely sources, including picnic baskets, to supplement their usual diet of berries,insects, and fish. Bears work throughout the summer

11、and fall to build up fat stores(15) to have energy enough to last them through their winter hibernations. Related tothis is their need to replenish their depleted reserves when they wake up in thespring. Food is generally scarce in the early spring and consequently the bears willgladly indulge in an

12、y foods that are high in proteins or fats. This is the main reasonfor any incidents involving bears after they enter campsites in search of food.(20) Although this behavior may seem strange, it is merely the result of natureequipping the bears with a variety of traits that allow them to remain well

13、fed inincreasingly human-populated habitats. Specifically, the American black bear,Ursus americanus, has color vision, which most other animals lack. Black bearshave been observed by scientists using this unique enhancement to distinguish(25) between varying food items at close range. On top of this

14、, bears have an acutesense of smell and can use their especially sensitive lips to locate food. Thesesensory talents contribute to the bears remarkably high intelligence and curiosity,giving them the ability to open closed containers if they believe food is inside.Their exploratory and navigational

15、skills are also worthy of notemost bears will(30) maintain vast territories to be sure they can obtain food from a variety of sources.Bears may even vary their sleep cycles in areas where there is a large degree ofhuman activity, either feasting on road-side garbage during the day or scouringcampsit

16、es for leftovers at night.（分数：4.00）(1).The primary purpose of the passage is to（分数：1.00）A.offer a comparison between television programming and real-world eventsB.describe the conditions under which a bear will enter human habitatsC.explain the different means by which bears secure nutritious foodD.

17、discuss new evidence concerning the difficulty of controlling bearsE.(E) resolve a controversy surrounding the foraging behavior of bears(2).The author mentions all of the following as potential food sources for bears EXCEPT:（分数：1.00）A.berriesB.general storesC.insectsD.fishE.(E) picnic baskets(3).It

18、 can be inferred from the passage that which of the following is true of bears?（分数：1.00）A.They are particularly resourceful.B.They must enter human habitats in order to survive.C.They cannot tolerate human food.D.They eat voraciously throughout the winter.E.(E) They have only one method of obtaining

19、 food.(4).The author includes a discussion of the American black bear, Ursus americanus, most likely in order to（分数：1.00）A.provide additional support for the unique feeding habits of bearsB.discount the theory regarding a bears ability to remain well fedC.evaluate the dispute between advocates of di

20、ffering theories regarding bear behaviorD.challenge recent research on the way in which bears secure foodE.(E) suggest further investigation of human interaction with bears13.ASSIMILATE: (A) to ascertain (B) to befuddle (C) to suffocate (D) to dissipate (E) to incorporate into（分数：1.00）A.B.C.D.E.Send

21、ing a robot into space to gather information is certainly a viable option,Line but should be regarded only as that-an option. Even the most technologicallyadvanced robots cannot and should not replace manned missions to outer space.Certainly it is cheaper and less dangerous to launch a computer prob

22、e(5) that can gather reams of data, but often the information obtained by a machineserves only to produce more questions than it answers. Therefore, the spaceprogram should allow manned missions to follow up on those initial information-gathering robotic ventures.While manned missions are more costl

23、y than are unmanned missions, they(10) are also more successful. Robots and astronauts use much of the same equipmentin space, but a human is much more capable of calibrating those instrumentscorrectly and placing them in appropriate and useful positions. A computer isoften neither as sensitive nor

24、as accurate as a human in managing the same terrainor environmental circumstances. Robots are also not as equipped as humans to(15) solve problems as they arise, and robots often collect data that is not helpful oreven desired. A human, on the other hand, can make instant decisions about whatto expl

25、ore further and what to ignore.While technological advances have allowed us to make incredible stridesin space exploration, they still cannot match the power of the human brain. This(20) “supercomputer“ is necessary in order to maintain a space program that can trulyadvance to the next level.（分数：2.0

26、0）(1).The passage supplies information to answer which of the following questions?（分数：1.00）A.What is the cost of launching a computer probe into space?B.What type of information can safely be ignored when exploring outer space?C.How much information can a computer probe gather in outer space?D.What

27、is the next level in space exploration?E.(E) Are unmanned space missions more economical than manned space missions?(2).According to the passage, all of the following are advantages of humans over robots EXCEPT:（分数：1.00）A.humans can more accurately manage the data collectedB.humans can apply critica

28、l thinking skills to new situationsC.humans can typically stay in outer space for longer periods of timeD.humans are more sensitive to environmental changesE.(E) humans are better at preparing instrumentation for use in space14.SKEPTICISM: (A) intricacy (B) qualmishness (C) credulity (D) disbelief (

29、E) narcissism（分数：1.00）A.B.C.D.E.When I was preparing for my two-week vacation in southern Africa, ILine realized that the continent would be like nothing I had ever seen. I wanted toexplore the urban streets as well as the savannah; its always been my goal tohave experiences on vacation that most ot

30、her tourists fail to find. When my plans(5) were finalized, I left for Africa. The cultural differences were stunning, and madefor plenty of laughter and confusion, but always ended up bringing smiles to ourfaces. Whats funny now, though, more than ever, is how ridiculous I must haveseemed to the pe

31、ople of one village when I played with their dog. Apparently, therole of dogs in America is nothing like it is in the third world.(10) When I walk the streets of my hometown now, I often find myself staring atall of the dogs and dog owners on the sidewalk. The way I see it, the Americandog lives for

32、 the thrill: a hug, a scratch behind the ears, a new chew toy, anotherchance to fight against the leash it knows is only six feet long. Dog owners loveto believe their animal is smart, while people whove never owned a dog tend to(15) believe the opposite. With a little training, the dogs dont bark,

33、bite, or use thesofa as a toilet, but they do provide years of unconditional affection and loyalty,plus the occasional lame-brained escapade at which human onlookers can laugh.I am convinced African dogs could clobber their American counterparts. Therelationship between a typical African and his dog

34、 is one of tangible mutualism.(20) I say tangible because the African sees himself as the dominant creature not tobe bothered by the dog, but nevertheless responsible for providing for it. Hence,no attempts at behavioral training are ever made on African dogs. Instead, theAfrican seizes power with a

35、 chunk of scrap meat and a bowl of water. The dogsoon learns to quit yapping and biting at the hand that feeds him. Never does(25) the African speak to the animal. Im not even sure such dogs get names. Theirbehavior becomes interestingly balanced, however, much to the surprise of thecompassionate Am
