一道高中英语选择题(The businessman )The businessman is so busy that he often forgets ____ his coat.A.doing upB.doing onC.to do up D.to do on为什么?
选C
忘记做某事用不定式,忘记做过的某件事用动名词
do up整理(衣服)

选 C
那个商人太忙了以致他经常忘记整理他的外套。
这里是考察短语do up， 整理的意思。还有forget的句型
forget to do sth 忘记了去做某事，说明还没做。
forget doing sth 忘记做过某事，说明已做
根据意思， 选 C

C.to do up
forget to do 解释为忘记去做某事
forgot doing 解释为忘记做过某事
这里应该是说他总是忘记去收拾好他的大衣
do up解释为收拾之类的意思

商人很忙碌，因而他时常忘记扣上他的外套
DO UP 扣扣子的意思..
选择C
而A意思是他忘记已经扣上了外套.

选C
首先，do up(收拾齐整)，是个固定词组，而没有do on这个搭配，所以排除B,D
其次，forget to do sth.[忘记去做某事（未做）]，符合题意，而forget doing sth.[忘记已做过某事（已做）]，与题意不符，故排除。

选C
forget to do sth 忘记了去做某事，说明还没做。
forget doing sth 忘记做过某事，说明已做 。
on表示穿着的状态，而题目要求的是表示动作，即使不知道do up 的意思可用排除法选择C。
