27、 aspect, or attitude to the Sun. Floridas ancient scrub demonstrates this principle. Its soil is pure silica, so barren it supports only lichens as ground cover.(It does, however, sustain a sand-swimming lizard that cannot live where there is moisture or plant matter (5) the soil.) Its climate, desp

28、ite more than 50 inches of annual rainfall, is blistering desert plant life it can sustain is only the xerophytic, the quintessentially dry. Its altitude is a mere couple of hundred feet, but it is high ground on a peninsula elsewhere close to sea level, and its drainage is so critical that a differ

29、ence of inches in elevation can bring major changes in its plant communities. Its aspect is flat, direct, brutaland subtropical. (10) Floridas surrounding lushness cannot impinge on its desert scrubbiness. This does not sound like an attractive place. It does not look much like one either; Shrubby l

30、ittle oaks, clumps of scraggly bushes, prickly pear, thorns, and tangles. “It appear Said one early naturalist,“ to desire to display the result of the misery through which it has Passed and is passing.“ By our narrow standards, scrub is not beautiful; neither does it meet (15) our selfish utilitari

31、an needs. Even the name is an epithet, a synonym for the stunted, the scruffy, the insignificant, what is beautiful about such a place? The most important remaining patches of scrub lie along the Lake Wales Ridge, a chain of paleoislands running for a hundred miles down the center of Florida, in mos

32、t places less than ten miles wide. R is relict seashore, tossed up millions of years ago when ocean levels (20) were higher and the rest of the peninsula was submerged. That ancient emergence is precisely what makes Lake Wales Ridge so precious: it has remained unsubmerged , its ecosystems essential

33、ly undisturbed, since the Miocene era. As a result, it has gathered to itself one of the largest collections of rare organisms in the world. Only about 75 plant species survive there, but at least 30 Of these are found nowhere else on Earth. （分数：1.00）(1). What does the passage mainly discuss?（分数：0.1

34、0）A.How geographers define a placeB.The characteristics of Floridas ancient scrubC.An early naturalists opinion of FloridaD.The history of the Lake Wales Ridge(2). The author mentions all of the following as factors that define a place EXCEPT（分数：0.10）A.altitudeB.soilC.life-formsD.aspect(3). It can b

35、e inferred from the passage that soil composed of silica（分数：0.10）A.does not hold moistureB.is found only in FloridaC.nourishes many kinds of ground coverD.provides food for many kinds of lizards(4). The word“sustain“ in line 6 is closets in meaning to（分数：0.10）A.selectB.strainC.supportD.store(5). The

The word “it“ in line 22 refer to（分数：0.10）A.FloridaB.the peninsulaC.the Lake Wales RidgeD.the Miocene era(10). The passage probably continues with a discussion of（分数：0.10）A.ancient s

39、crub found in other areas of the countryB.geographers who study Floridas scrubC.the climate of the Lake Wales RidgeD.the unique plants found on the Lake Wales RidgeSome animal behaviorists argue that certain animals can remember past events, anticipate future ones, make plans and choices, and coordi

40、nate activities within a group. These scientists, however, are cautious about the extent to which animals can be credited with conscious processing. (5) Explanations of animal behavior that leave out any sort of consciousness at all and ascribe actions entirely to instinct leave many questions unans

41、wered. One example of such unexplained behavior: Honeybees communicate the sources of nectar to one another by doing a dance in a figure-eight pattern. The orientation of the dance conveys the position of the food relative to the suns position in the sky, (10)and the speed of the dance tells how far

42、 the food source is from the hive. Most researchers assume that the ability to perform and encode the dance is innate and shows no special intelligence. But in one study, when experimenters kept changing the site of the food source, each time moving the food 25 percent farther from the previous site

43、 foraging honeybees began to anticipate where the food source would (15)appear next. When the researchers arrived at the new location, they would find the bees circling the spot, waiting for their food. No one has yet explained how bees, whose brains weigh four ten-thousandths of an ounce, could ha

44、ve inferred the location of the new site. Other behaviors that may indicate some cognition include tool use. Many (20)animals, like the otter who uses a stone to crack mussel shells, are capable of using objects in the natural environment as rudimentary tools. One researcher has found that mother ch

45、impanzees occasionally show their young how to use tools to open hard nuts. In one study, chimpanzees compared two pairs of food wells containing chocolate chips. One pair might contain, say, five chips and three chips, the other (25)our chips and three chips. Allowed to choose which pair they wante

46、d, the chimpanzees almost always chose the one with the higher total, showing some sort of summing ability. Other chimpanzees have learned to use numerals to label quantities of items and do simple sums. （分数：0.99）(1). What does the passage mainly discuss?（分数：0.09）A.The role of instinct in animal beh

47、aviorB.Observations that suggest consciousness in an anima behaviorC.The use of food in studies of animal behaviorD.Differences between the behavior of animals in their natural environments and in laboratory experiments.(2).

49、ood sourcesD.T identify the type of nectar that is available(4). The word “yet“ in line 16 is closest in meaning to（分数：0.09）A.howeverB.sinceC.generallyD.so far(5). What did researchers discover in the study of honeybees discussed in paragraph 2?（分数：0.09）A.Bees are able to travel at greater speeds than scientists thought.B.The bees could travel 25% farther than scientists expected.C.Th
