英语动词短语做主语的使用方法,
问题描述:
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
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
