英语中 “动词短语” 可以做主语吗?(除了祈使之外,其实内也不算主语)请英语高人回答.
“动词短语” 相当于一个行为动词,不可以做句子主语,只能做句子谓语,但是,动名词短语可以做主语,也就是动名词做主语,例如
(1)Finging a sastisfactory job nowadays is not easy 中的 Finding a satisfactory job 属于动名词短语,作主语,但是find a satisfactory job 不可以做主语
(2)I am looking for my pen under the bed 中的,look for 是个短语动词,在句子中就是动词短语look for my pen 只能做句子谓语,不能做主语
(3) To learn English well is of great importance to us all 中动词不定式短语可以做主语,但是 learn English well 却不能做主语
总之:能做主语的有下面成分
(1)名词可以做主语 :The boy is a student
(2)代词可以做主语:He is a doctory
(3)数次可以做主语:The first is the best
(4)The +形容词可以做主语:The rich should help the poor
(5)动词不定式可以做主语:To speak with a strange must be so careful
(6)动名词可以做主语:Smoking is greatly harmful to our health
(7)主语从句可以做主语:What I have done is of great benefits to you
再问: 看出您英语很棒,我还想问您一个问题,一个英语句子本质上算是一个“动词”还是一个”名词“,还是根本就不能这样说 。
