这里附上姐姐的原解释: after可以引导从句,没问题。 我觉得这里的D选项的exhausting确实存在很多问题,见Ron上次v-ing的讲课(不复述了,please help yourself)。当你用v-ing表示动作的时候,要注意动作的主语。到底是谁在exhausting? It is not clear. 这道题就类似于: I regularly deposit some of my wages into an account intended to sustain my tuition after entering MBA. 这句话这么看,问题就很明显了。从逻辑上entering的主语应该是我。但是从句子结构上看, an account [intended to sustain my tuition (after entering MBA)] 这里仿佛entering的主语是account。所以不合逻辑。 你对比一下after falling那道题,是不是falling的主语很明显啊?
OG对比题: 86. The results of the company’s cost-cutting measures are evident in its profits, which increased 5 percent during the fi rst 3 months of this year after it fell over the last two years. (A) which increased 5 percent during the first 3 months of this year after it fell (B) which had increased 5 percent during the first 3 months of this year after it had fallen (C) which have increased 5 percent during the first 3 months of this year after falling -----profits (D) with a 5 percent increase during the first 3 months of this year after falling (E) with a 5 percent increase during the first 3 months of this year after having fallen
附上论坛链接及解释 http://www.beatthegmat.com/new-issue-1000-73-t68329.html C: oil reserves are exhausted - This means that the oil reserve will exhaust after its prolong usage. D: exhausting its oil reserves - This means that the state deliberately wants to exhaust its oil reserves.
D> The construction in D is "fund intended to sustain the state’s economy after exhausting its oil reserves , or fund + participle phrase after (fund+) participle phrase. " fund intended to sustain the state's economy" makes sense. "fund exhausting its oil reserve" doesn't make sence. So D is out.
