　　参考答案及解析：

　　1.The correct answer is C

　　Explanation

　　Hopes for “permanent victories against many diseases” have been “blighted,” or dashed or crushed, by the “proliferation of drug-resistant strains of bacteria and viruses.”

　　2.The correct answer is E

　　Explanation

　　Choice (E) is correct. “Debilitated” refers to an often temporary loss of strength, less severe than becoming “incapacitated,” or deprived of strength or ability. Since the impairment is serious but temporary, doctors might very well encourage Tom to expect “recovery” after a period of convalescence.

　　3.The correct answer is A

　　Explanation

　　The sentence indicates that “an onslaught of glaciers” once changed things in “northern forests” but not in “forests in the southern region of the continent.” It makes sense to suggest that the forests that did not have their “flora and fauna,” or plants and animals, wiped out by glaciers would be “rich in plant and animal diversity,” or would contain a vast amount of different plants and animals.

　　4.The correct answer is E

　　Explanation

　　Keep in mind that the words after the colon will explain or exemplify the first part of the sentence. This means that the missing term describes someone who “seemed to know what dignitaries and foreign leaders were thinking.” Such a person is said to have great “perspicacity,” or perception.
