大全10 A large rise in the number of housing starts in the coming year should boost new construction dollarsby several billion dollars, making the construction industry’s economic health much more robust than five years ago. (A) making the construction industry’s economic health much more robust than five years ago (C) making the construction industry’s economic health much more robust than it was five years ago 答案是c og251. The gyrfalcon, an Arctic bird of prey, has survived a close brush with extinction; its numbers are now five times greater than when the use of DDT was sharply restricted in the early 1970's. . (A) extinction; its numbers are now five times greater than (B) extinction; its numbers are now five times more than (C) extinction, their numbers now fivefold what they were Florida will gain another quarter-million jobs this year alone, many of them in such high-paying fields as electronics and banking,making the state’s economy far more diversified than it was ten years ago. 其实根据这3个句子。可以看出than之后需不需要补助词。其实主要问题不是时态前后不一置。 在og251的a项中,than前后时态不一致,但确实把it was给省略了。而且这里it was是可以省的,并无歧义也很简洁。 在大全10和最后一句里,it was 需要补出,个人认为是因为比较结构出现在了伴随性状语中。 具体为什么,我也说不清,可能是为了避免歧义(我不是很确定)。但大家记住这个规律即可。
