动名词短语作主语和不定式的区别
spending too little time on the computer 是动名词短语作主语 also shows是谓语 .为什么不是不定式?而是谓语 spending too little time on the computer also shows the users are lonely.
答
主语一般是名词和动名词。一般不用动词不定时做主语，因为会显得头重脚轻，所以英语里如果是不定时做主语时一般会将它成It作形式主语，动词不定式放句尾做真实主语，如：做家务事她的义务：一般不会写成：to do homework is his duty,而是写成：It is his duty to do homework.
至于位于为什么是 also shows 而不是 also to show.是因为动名词作主语时，谓语动词要用单数，所以加s.而不是不定式。
可以参考一下。。。。
答
动名词和不定式作主语的区别在于：
动名词常表示泛指,而不定式表具体特指,往往表示将来行为.如：
Looking after the children is her job.
To look after the children is her job this afternoon.
