27、 differ from other animals in the way they regulate body temperature. Ways of 1 the difference have become more accurate and meaningful over time, but popular terminology still reflects the old 2into warm blooded and cold blooded species; warm blooded included mammals and birds, 3all other creatures
28、 were considered cold blooded. As more species were studied, it became evident that this classification was 4. A fence lizard usually has a body temperature only a degree or two below that of humans and so is not cold. Therefore the next distinction was made between animals that maintain a 5body tem
29、perature and those whose body temperature varies with their environment. But this classification also 6inadequate, because among mammals there are many that vary their body temperatures during hibernation. Furthermore, many invertebrates that live in the 7of the ocean never experience a change in th
30、e chill of the deep water, and their body temperatures remain constant. The current distinction is between animals whose body temperature is regulated chiefly by internal metabolic processes and those whose temperature is regulated by the 8. The latter do so mainly by moving to favorable sites or by
31、 changing their exposure to 9 sources of heat. Mammals and birds also regulate their temperature by choosing favorable environments, but primarily they regulate their temperature by 10a variety of internal adjustments.（分数：20.00）填空项1:_填空项1:_填空项1:_填空项1:_填空项1:_填空项1:_填空项1:_填空项1:_填空项1:_填空项1:_五、READING CO
32、MPREHENSIO(总题数：10，分数：30.00)29.PART V READING COMPREHENSION_30.SECTION AIn this section there are several passages followed by ten multiple-choice questions. For each question, there are four suggested answers marked A, B, C and D. Choose the one that you think is the best answer._(l)People in the Un
33、ited States in the nineteenth century were haunted by the prospect that unprecedented change in the nations economy would bring social chaos. In the years following 1820, after several decades of relative stability, the economy entered a period of sustained and extremely rapid growth that continued
34、to the end of the nineteenth century. Accompanying that growth was a structural change that featured increasing economic diversification and a gradual shift in the nations labor force from agriculture to manufacturing and other nonagricultural pursuits. (2)Although the birth rate continued to declin
35、e from its high level of the eighteenth and early nineteenth centuries, the population roughly doubled every generation during the rest of the nineteenth century. As the population grew, its makeup also changed. Massive waves of immigration brought new ethnic groups into the country. Geographic and
36、social mobilitydownward as well as upwardtouched almost everyone. Local studies indicate that nearly three-quarters of the populationin the North and South, in the emerging cities in the Northeast and in the restless rural counties of the Westchanged their residence each decade. As a consequence, hi
37、storian David Donald has written, Social atomization affected every segment of society, and it seemed to many people that all the recognized values of orderly civilization were gradually being eroded. (3)Rapid industrialization and increased geographic mobility in the nineteenth century had special
38、implications for women because these changes tended to magnify social distinctions. As the roles of men and women played in society became more rigidly defined, so did the roles they played in the home. In the context of extreme competitiveness and dizzying social change, the household lost many of
39、its earlier functions and the home came to serve as a haven of tranquility and order. As the size of families decreased, the roles of husband and wife became more clearly differentiated than ever before. In the middle class especially, men participated in the productive economy while women ruled the
40、 home and served as the custodians of civility and culture. The intimacy of marriage that was common in earlier periods was rent, and a gulf that at times seemed unbridgeable was created between husbands and wives.（分数：6.00）(1).According to the passage, as the nineteenth century progressed, the peopl

42、s economy expandedB.women had more opportunities for employment in the western United States than in other regionsC.the home after 1820 was a superior social entity to that of the eighteenth centuryD.increased social fragmentation negatively affected middle class family(3).All the following can be i
43、nferred from the passage EXCEPT that_.（分数：2.00）A.more and more people were leaving the farm to take up nonagricultural jobsB.there was a significant change of meaning in the word familyC.people no longer wanted to get marriedD.the rapid economic growth lasted for more than half a century(l)Joan of Arc would be proud.
