一句语法填题:
She read the letter through before sending it, _______ (check) for spelling mistakes.
答案:checking,分析是:这里是用现在分词表伴随。
疑问:但为什么不填不定式 to check 呢?可以理解为用不定式表目的啊!
不定式表目的时,前面不能用逗号。例如:
They will go to the station to meet the guests. 他们将去车站接客人。
Jesus Christ came into the world to save us from our sins. 基督降世拯救我们摆脱罪恶。
Rescuers worked in relays to save the trapped miners. 救援人员轮班工作以营救遇难的矿工。
The Government set up a working party to look into the problem. 政府成立了工作组调查那个问题。
所以,你这道题不能填不定式 to check。
