一、有“建议”的意思。
advise、propose也有此意，请比较它们用法的异同：
1) 都可接名词做宾语
She suggested/ advised/ proposed an early start. 她建议早一点出发。
We suggested/ advised/ proposed a visit to the museum the next day.
我们建议明天去参观博物馆。
2) 都可接动名词做宾语
I suggested/ advised/ proposed putting off the sports-meet. 我建议将运动会延期。
They suggested/ advised/ proposed waiting until the proper time.
他们建议(我们)等到恰当的时机才行动。
3) 都可接that宾语从句，that从句用should+动词原形，should可以省略。
She suggested/ advised/ proposed that the class meeting (should) not be held on Saturday.
她建议班会不要在星期六举行。
We suggested/ advised/ proposed that he (should) go and make an apology to his teacher.
我们建议他去向老师道歉。
4) advise可接动词不定式复合宾语，propose可接不定式做宾语。
I advised him to give up the foolish idea. =I suggested/proposed his/him giving up the foolish idea.我建议他放弃那愚蠢的念头。(suggest和propose在口语里可接动名词的复合宾语)。
We proposed to start early. =We proposed starting early.我们建议早一点出发。(接不定式不用suggest和advise)
