It’s no use crying over spilt (倾倒出)milk.① It +be +no good /use doing…做…无益/无用It’s a waste of time thinking hard about the past.②It +be +a waste of time doing…做…是浪费时间The book is worth reading.③It +be +worth doing …做…值得There is no harm in doing so.④There +be +no +n. +in +doing …做…没有…2. 作宾语 (动词宾语和介词宾语)He finished reading the book yesterday.I enjoy learning English.
