Question

ask sb's help in doing 还是ask sb's help to do

遇到这个题， 虽然知道 ask sb todo something 可是加了个名词help 就傻了
类似还有 ask sb's aid in doing/to do
前面有一道题是 ask sb's aid in doing 答案解释说 因为 aid是名词 所以后面跟 in doing， 但感觉比较牵强； 难道后面有名次就一定要跟 in doing 么？ 等待更确认的答案

Answer 1

正确的:ask sb for help to do something 不能用sb's help
因为这是不正规的英语用法
for help这里做的是一种补充的作用,因为去了以后还是正确的句子

Answer 2

ask sb's help in doing

因为help后面不能加不定式to

Answer 3

这句不是在考ask的用法了,是在说help这个用法,help to do/in doing
