1、用法不同

advise后面加somebody (not)to do...

如：I advise my father to stop smoking.

suggest后面必须加somebody(或者somebody's)doing...

如：I suggest my father( father's) stopping smoking.

2、局部含义不同

suggest有暗示的意思，advise没有。

3、后接形式不同

advise后可以直接跟人称代词作宾语，如：advise sb. to do sth.; advise sb. against(doing) sth.; advise sb. on/ about sth.;而suggest后一般用suggest to sb that…形式。

suggest的常见错误：

1.他建议去散散步。

误He suggested to go for a walk.

正He suggested going for a walk.

正He suggested that we (should) go for a walk.

解析：suggest后不能接动词不定式或“宾语＋动词不定式”结构。在表示“建议某人做某事”时，可接动名词或接that从句来表示，从句中的谓语多用should加动词原形构成，should可省略。

2.她打哈欠表示她很困了。

误：Her yawn suggests that she should be sleepy.

正：Her yawn suggests that she is sleepy.

解析：suggest作“暗示，表明”解后接that从句时，从句中一般不用虚拟语气。

3.建议性感，但是不能太过招摇。

误：suggest at sexiness but don't flaunt it.

正：suggestsexiness but don't flaunt it.

分析：suggest是及物动词，后面可直接跟宾语，不需要不介词at。
