源于一段对话，前面大意是M向W问路:
M：Got it. Ah...Youre not driving that way, are you?
W：Sorry.
M：Well, no harm in asking. Thanks for your help.
no harm in asking 是 there isno harm in asking. 之省略。
意思是：“问路没坏处。”
英语常用结构： There is no + 抽象名词 + in doing... : 做某事没好处/坏处/意义......
记住、会用下列表达，你就没疑问了：
There is a lot of + 表示“作用与功效、好处、坏处、利益、用途、道理、意义、乐趣”等含义的不可数名词 + in sth.
其中，in sth. 表示“在（做）某事方面”，可以看作“方面状语”。
表示“作用与功效、好处、坏处、利益、用途、道理、意义、乐趣”等含义的不可数名词，容易见到的有：
use, advantage, good, harm，sense, point, fun, merit, pleasure 等。比如：
1. There is no use in arguing with him. 与他争论没用。
2. There is no advantage in going so early. 去那样早一点好处都没。
3. There is no sense in beating about the bush. 旁敲侧击说话没道理。
4.There is no point in coming back. 回来也没意义了。
5. There is no good in gossiping here. 这不是拉闲话的地方。
6. There is no fun in winning a thing unless you play for it. 不费心思得来的东西实在没的意思是。
7. There is no pleasure in having nothing to do. 无事可做真无趣。
8. There is no disgrace in being poor. 贫穷并不丢脸。
9. There isno harm in asking. 不耻下问没坏处。
