OG 265 求助关于现在完成时的问题

265. Thomas Eakins’ powerful style and his choices of subject—the advances in modern surgery, the discipline of sport, the strains of individuals in tension with society or even with themselves—was as disturbing to his own time as it is compelling for ours.

(A) was as disturbing to his own time as it is

(B) were as disturbing to his own time as they are

(C) has been as disturbing in his own time as they are

(D) had been as disturbing in his own time as it was（B）

(E) have been as disturbing in his own time as

Choice B, the best answer, exhibits correct subject-verb agreement and uses appropriate verb tenses. Choices A, C, and D contain errors of agreement: the compound subject style and... choices of subject requires a plural verb and should correspond to the plural pronoun they, not it. Further­more, C wrongly shifts to the present perfect tense (has been) to characterize something that happened in the past, while D uses the past tense was to characterize something that is happening in the present. In E, while the plural have agrees in number with the compound subject, the use of the present perfect tense (have been) is inappropriate for characterizing the effect of Eakins' work in his own time.

为何解释中说现在完成时不能用去过去发生的动作？记得现在完成时是可以用于描述在过去某不确定时间点发生的动作的。请NN帮忙解释，谢谢

我查了书

你说的这个情况是已完成用法：指动作或过程发生在说话之前某个没有明确说出的已过去时间，现在已经完成了，并与现在的情况有联系。并且不与表示时间的状语连用。

而这题里的实际用法并没有完全适用这个已完成用法。

它表示的是两个时间段里的比较。

GMAT语法中在过去发生的动作一般用过去时来表达，比较简洁明了。

谢谢CAROLHIDE的解释，说的非常清楚，还想请教下，这里如果用HAS BEEN的话，是否有从过去某一时间开始，一直延续到现在的意思？

carolhide

对的，现在完成时在GMAT的用法中一般就是表达从过去某个时候开始一直延续到现在的状态。

谢谢CORALHIDE的耐心指点。

总结下：这题C选项中首先HAS BEEN描述一个过去的状态并不合适，其次为了比较的平行应该采用一般过去时从而和AS THEY ARE对应
