问题描述:

The retired man donated most of his savings to the school damaged by the earthquake in Yushu,
后面句子是enabling the students to return to their classrooms.我要问的是为什么不是having enabled呢..

前面说了一帮都是原因,后面则是结果。这里是进行时做结果状语。having enabled是现在完成时,用它时态就不对了。捐钱的时候还没完成完成了,而是捐钱给他们,然后是她们重新回到学校。

又没有标志着用现在完成时的标志词,干么用现在完成时,一结果,用ING就行了

非谓语动词的知识,位于才有时态。having enabled是现在分词的完成式,表示此动作发生在谓语动词 (donated)前,切有因果联系,与本局不符。
例如 Having driven all day,we were rather tired.

动名词短语用作目的状语

having enabled是现在完成时,用它时态就不对了.捐钱的时候还没完成完成了,而是捐钱给他们,然后是她们重新回到学校
此题正确答案为enabling
此题为2010年江苏省高考题
