问题描述:

The retired man donated most of his savings to the school damaged by the earthquake in yushu,_____the students return to their classrooms.
A enabling
B having enabled
C to enable
D to have enabled

A,这个退休人把他大部分的积蓄都捐给了在玉树地震中受灾的学校,是学生重新回到了教室,enabling表示结果哪为什么是用ing形式呢?还有为什么having enabled不行呢?ing 形式表结果,是状语从句,如果用having 表示已经发生的事情,但是这个题中的应该是先捐钱,在捐钱的同时使学生回到教室,也不能用toenable,如果要用的话就要把句子前面的逗号去掉hegotheretowatchher,to要用在句子里面表示目的,不能用逗号隔开
