词组get down to sth/doing sth 表示“开始做某事,认真做某事或者重视某事物”,我们 来举两个例子,Let's get down to business.我们开始办正事吧.It's time I get down to some serious work.该是我认真干点事情的时候了.所以选择C
to这个词一般情况下只能做介词、副词或动词不定式的标志词(小品词).
当它后面接动词时,它是小品词;
当它后面接宾语(名词、代词、动名词、副词、介词短语等都可以用作宾语但动词永远不能做宾语)时,它是介词;
当上述两种情况都不符合时,to往往是副词,而且当它做副词时只能表示“苏醒”、“靠岸”等义.
但是对于填空中既有do又有doing的时候,就需要靠平时积累的短语的固定形式用法了
具体有一些TO短语的分类,是介词还是不定式,你自己细细看吧
B doing
get down doing something 开始认真做某事
c.get down to
这里的to是介词,当to作介词时,其后接名词或动名词;作不定式时,其后接动词原形。
eg: look forward to doing, to 是介词
plan to do sth. to 是不定式
