改错题 8.Over a range of frequencies from 100 to 5,000 hertz, monkeys and marmosets have a hearing sensitivity remarkably similar to humans, above which the sensitivity begins to differ.
【正确答案】 E
【答案解析】Logical predication; Agreement
This sentence expresses two ideas: the similarity in monkey, marmoset, and human hearing in the stated frequency range, and the divergence in hearing sensitivity above that range. The second idea is introduced by above which. Above which should be immediately preceded by the antecedent of which, that is, the 100-5,000 Hz range. Also, the subject and verb must agree in number.
A In this construction, above which ... illogically modifies either humans or a hearing sensitivity remarkably similar to humans, rather than the frequency range.
B The singular subject in this version, the hearing sensitivity... , is not accompanied by the correct singular verb form (is).
C Above which is incorrectly preceded by similar, rather than by the expression of the frequency range. The sentence appears, illogically, to compare humans over a range of frequencies with monkeys' and marmosets' hearing sensitivity.
D Above which is incorrectly preceded by similar, rather than by the expression of the frequency range. The sentence appears, illogically, to compare humans over a range of frequencies with monkeys' and marmosets' hearing sensitivity.
E Correct. Above which is correctly preceded by a range of frequencies... , and the verb is is in its proper singular form.
The correct answer is E.
