终于找到了一个能说服自己的说法, 首先,OG 69中,while表示当什么……的时候,表示两个动作同时发生,A和B就不对了。属于语法正确,但不符合习惯。 其次,OG 31中,while willing to,这个while+形容词的省略结构,GMAT认为是语法错误,OG-11解释到,Have a disinclination is wordy (the verb disinclined is preferred) and, when followed by while willing, creates an incomplete construction。应该补充一个逗号,原因在于,while引导的从句做状语,必须加逗号。 Incorrect: I couldn't pass the driving test even thoughI studied hard. Correct: I couldn't pass the driving test, even though I studied hard. ? 状语从句放于句尾时,如果对整个句子来讲是必须的,则不要用逗号分开,反之可以用逗号分开,但在although, though, even though, no matterwhat/how/when,since,whereas, while 所引导的状语从句前一定要用逗号分开。 这个例子就是如此,这里while+形容词,省略了主语+be,完全没错!另外我查阅了GMAT 阅读和语法的大量实例,while 做状语的时候,都是有逗号的! |
