OG10-48，这道题对A的解释是living前面没有指明动作发起者，如果按照这个解释的话，新东方补充练习第24题的A选项的sitting前面是否也应该指明动作发起者呢？？ 麻烦NN解释一下 OG10-48. The golden crab of the Gulf of Mexico has not been fished commercially in great numbers, primarily on account of living at great depths—2,500 to 3,000 feet down. (A) on account of living (B) on account of their living (C) because it lives (D) because of living (E) because they live As used in choices A, B, and D, the phrases on account
of and because of are unidiomatic; because, which appears in C and E, is preferable here since because can introduce a complete subordinate clause explaining the reason why the golden crab has not been fished extensively. B and E also produce agreement errors by using the plural pronouns their and they to refer to the singular noun crab.
Choice D, like A, fails to provide a noun or pronoun to perform the action of living, but even with its the phrases would be more awkward and less clear than it lives. C, which uses because and it as the singular subject of a clause, is the best choice. 24．A common disability in test pilots is hearing impairment, a consequence of sitting too close to large jet engines for long periods of time. (A) a consequence of sitting too close to large jet engines for long periods of time (B) a consequence from sitting for long periods of time too near to large jet engines (C) a consequence which resulted from sitting too close to large jet engines for long periods of time (D) damaged from sitting too near to large jet engines for long periods of time（A） (E) damaged because they sat too close to large jet engines for long periods of time Choice A is correct. Choice B is faulty because a consequence from is unidiomatic and because the modifying phrases are awkwardly placed. In C, a consequence which resulted is redundant in that consequence expresses the idea of result, and from is again wrong. D and E both present dangling modifiers in that nothing named in the main clause can be said to be damaged; i.e., the pilots’ hearing has been damaged, but their hearing impairment has not. The question is of middle difficulty. |
