答案E
解析 Logical predication; Agreement
This sentence explains the advantages of long legs to the North American moose. Since the sentence contains multiple relationships among pronouns, nouns, and modifiers, it is important that the various elements be clearly connected. The structure of the sentence makes it unclear whether stepping easily over downed trees is intended to modify the main subject, the North American moose’s long legs, or the pronoun it. Although it presumably refers to the North American moose, it does so only obliquely, because moose does not appear in noun form in the sentence. The best way to construct this sentence is to make moose the subject of the main clause so that both occurrences of it have a clear antecedent. Because stepping easily over them is set off by commas from the preceding and ensuing clauses and because the apparently intransitive verb leap intervenes between downed trees and them, it is unclear whether them refers to the moose’s legs or the downed trees. The phrase leap or go around them should say leap over, because the point is that the predators must either leap over the downed trees (or go around them), not merely that the predators leap in the air or else go around the trees.
A The function of stepping easily over downed trees is unclear in relation to the rest of the sentence. The pronoun it refers only obliquely and unclearly to moose, because only the possessive form moose’s appears in the sentence. Furthermore, the final phrase should say leap over, not merely leap.
B The function of stepping easily over downed trees is unclear in relation to the rest of the sentence. The pronoun it refers only obliquely and unclearly to moose, because only the possessive form moose’s appears in the sentence. The plural pronoun them has no logical plural antecedent (surely the predators are not pursuing the moose’s legs, but the moose itself; nor are the predators pursuing the downed trees). Furthermore, the final phrase should say leap over, not merely leap.
C The plural pronoun them in pursuing them has no logical plural antecedent.
D The plural pronoun them has no logical plural antecedent {moose can be used as a plural, but because in this sentence the singular verb has is used, moose must be construed as being singular here). Furthermore, the final phrase should say leap over, not merely leap.
E Correct. The pronoun it refers to moose, and the pronoun them refers to trees. Also, the final phrase correctly says leap over or go around them.
The correct answer is E.
