题目

英语动词短语做主语的使用方法,
比如：walk and deep-breathe in parks and forests for the high level of anion in these areas can stimulate parasympathetic nerve system which can help the body relax.中walk and deep-breathe in parks and forests for the high level of anion in these areas 这个动词短语,后面can可以换做to吗?还有,supplement energy in time to keep blood sugar at an effective level.中supplenment ernergy 做主语,to可以换做can吗?如果可以互换,那么可以说：Study English can make someone crazy,或者Studying English can make someone crazy.这两种说法都对吗.请赐教.

答案

can不能换成to,如果换的话这句话语法错误,can在这句话中做谓语
第二句中的to可以换成can,to和can 都能用,只不过句子的意思变了,用to,这只是一个动词短语,用can则是一个句子
study和studying都能用,一个是原形,一个是ing形式,都能用
