umm...或许得修改下那句总结了,我也不知道哪里看来得.. 不过OG11-130里面确实指出来that不能够只能,要用who. 130. As a result of medical advances, many people that might at one time have died as children of such infections as diphtheria, pneumonia, or rheumatic fever now live well into old age. (A) that might at one time have died as children (B) who might once have died in childhood (C) that as children might once have died (D) who in childhood might have at one time died (E) who, when they were children, might at one time have died Parallelism + Agreement The sentence has one error in pronoun usage and two errors in parallelism. The pronoun who, rather than that, should be used to refer to people. Once, not the ambiguous and wordy at one time, is parallel to the adverb now, and in childhood, not as children, is parallel to into old age. Parallel structure involves not only how parallel elements are formed but also where they are placed in the sentence: here adverbs (once and now) should be placed first, followed by verbs (have died and five), and then by prepositional phrases (in childhood and into old age). A Who should replace that; once should replace at one time, in childhood should replace as children B Correct. This sentence correctly uses who to refer to people, parallel structures are maintained by using once to parallel now and in childhood to parallel into old age. C Who should replace that, in childhood should replace as children and should be placed after died to be parallel in position to into old age D Once should replace at one time, the parallel elements should appear in parallel positions E When they were children is awkward and not parallel to into old age in wording or placement; once should replace at one time |
