17. Bob Wilber became Sidney Bechet’s student and protégé when he was nineteen and, for a few years in the 1940’s, came as close to being a carbon copy of the jazz virtuoso in performance as anyone has ever come. (A) as anyone has ever come (B) as anyone ever had been (C) as anyone ever had done (D) that anyone ever did (E) that anyone ever came 答案a,我选c,为什么不对呢?
看了这道题我也不甚明白: 当然如果从单纯做题的角度,一开始就可以把D,E排除,B和C似乎也不应该把副词ever放在had的前面,那么就只剩下A了,不过问题是这里为什么不是...as anyone has ever done 呢?以前似乎做题都是把动词改成do,did或does的啊。当然,仔细看来这儿确实有点特殊,就是前面用的是过去时,后面用的是现在完成时,这两者的比较不象以前的...do as sb do或 ... have done as sb have那样简单,不过,难道过去时和现在完成时比较时有新的规则? 百思不得其解,不过真理越辩越明,请大牛不吝赐教。
