主语是抽象概念,非谓语动词,从句,谓语是用单数还是复数？

回答如下：
若主语是抽象名词、不可数名词、动名词、不定式、主语从句，谓语动词通常用单数形式。例如：
His absence from classes makes me very angry.
The money on the desk is mine.
His being late yesterday is true.
To live here is very pleasant.
For her to live here is my idea.
What to do next is not clear.
That he is in hospital is true.
What you said is not right.
但若上述主语是并列主语，谓语动词应该用复数形式。例如：
Water and fire are not incompatible.
To find problems and to settle problems are what we must do at present.
Listening, speaking, reading and writing are of great importance.
That he is out of work and that his wife is ill in bed are just what we leaders should be concerned about.
What you say and what you don't match up.

非谓语动词作主语时，谓语用单数。但如果两者并列，就像两个名词一样，使用复数形式。让我举两个例子。学好英语，听很重要。listengling是主语，动词是要学好英语，听和说很重要。这句话的主语是听和说，所以用动词are
