20. Never before in the history of music have musical superstars been able to command so extraordinary fees of the kind they do today. (A) so extraordinary fees of the kind they do today (B) so extraordinary fees as they are today (C) such extraordinary fees as they do today (D) such extraordinary fees of the kind today’s have (E) so extraordinary a fee of the kind they can today
KEY: C 我对 AS THEY DO TODAY 中的动词省略不清楚, 选了B, 在有情态动词的时候, 到底是保留情态动词还是保留实际动词, 从而用DO 代替? 谢谢.
另外句子的理解上也有问题,如果用are,只是强调现在的音乐家有这种能力,而用do,则表示现在的音乐家已经在使用这种能力,更加贴切一点八 印象中,如果补出的是be动词,后面直接跟表语的,不会跟复杂成分 be able to do不应该认为是情态动词
agree that do,则表示现在的音乐家已经在使用这种能力 but disagree 用are,只是强调现在的音乐家有这种能力 ,because "be able to" cannot be separate,and we see them as a entirety. In most of status,It isequal to can and is a情态动词
字典里有: he's no more able to read Chinese than i am. here we see that " be able to" is separate as " i am", so i guess there is an objective grammar rule for us to figure out the two choices, but i don't know what it is.
