(C) and also a body of work of importance in polit­ical science is representing

(D) an important body of work in political science and has been representative of

(E) and as political science an important body of work too, represent

我有疑問的是選項D

關於現在完成式部分

我一開始的理解是這樣: the federalist 這部論文,呈現了3個不同作家的作品

這部論文已經完成了嗎??是阿,在過去完成的

那麼論文的影響有一直延續嗎??有阿

所以我覺得用現在完成式並沒有不合理的地方

og的解釋如下: D, employing the present perfect tense, suggests that the situation of triple authorship is no longer the case

我不理解為什麼說"no longer the case"??

完成是不是有隱含延續的動作含意嗎??????

困惑中

现在完成时表明将来不一定这样. OG这样解释我们就这样理解吧.

OG里有一些其他相似的例子
