不加ING
advise与suggest
是“向……建议”的意思,两者的区别是：advise后面加somebody (not)to do...,而suggest后面必须加somebody(或者somebody’s)doing...,当然两者都可以接宾语从句,注意宾语从句的动词形式必须是(should) (not) do.如下面三个句子：
a.I advise my father to stop smoking.
b.I suggest my father( father’s) stopping smoking.
c.I advise/suggest (that) my father (should) stop smoking.
advise与suggest的另一个区别是：可以说suggest something to somebody,而advise一般不能接something作宾语.
