參考答案

(1) 2

This is a Vocabulary question. The word being tested is threatened. It is highlighted in the passage. To threaten means to speak or act if you will cause harm to someone or something. The object of the threat is in danger of being hurt, so the correct answer is choice 2, “endangered”

(2) 2

This is a Factual Information question asking for specific information that can be found in paragraph 3. The correct answer is choice 2, reduced water absorption. The paragraph explicitly states that the reduction of vegetation greatly reduces water absorption. Choice 4, reduced water runoff, explicitly contradicts the paragraph, so it is incorrect. The “spaces in the soil” are mentioned in another context: the paragraph does not say that they increase, so choice 3 is incorrect. The paragraph does not mention choice 1.

(3) 1

This is a Vocabulary question. The word being tested is delicate. It is highlighted in the passage. The correct answer is choice 1, “fragile” meaning “easily broken.” Delicate has the same meaning as “fragile.”

(4) 1

This is a Factual Information question asking for specific information that can be found in paragraph 5. The correct answer is choice 1: border areas have difficulty ”adjusting to stresses created by settlement. ” The paragraph says that “expanding populations,” or settlement, subject border areas to “pressures,” or stress, that the land may not ”be able to respond to.” Choice 2 is incorrect because the paragraph does not discuss ”fertility” after desertification. Choice 3 is also incorrect because “irrigation” is not mentioned here. The paragraph mentions “increasing populations” but not the difficulty of “attracting populations,” so choice 4 is incorrect.

(5) 4

This is a Vocabulary question. The word being tested is progressively. It is highlighted in the passage. The correct answer is choice 4, “increasingly.” Progressively as it is used here means “more,” and “more” of something means that it is increasing.
