propose和suggest的区别

propose是建议，打算的意思，後接名词。比如We propose an early start tomorrow.我们打算明天早早出发。suggest 也是建议，提议的意思，一般跟that从句。但它具有启发性，比如The specialist suggested that children should not eat too much sugar.专家建议儿童不该吃太多的食糖

前者：常用于正式地提出建议。
I propose Sue Wilson for treasurer.
It was proposed that we postpone making a decision until next month.
后者：语气较委婉，指提出些个不成熟的建议，或发表点参考意见。
I suggest we have dinner first, and then watch the movie.
Can anyone suggest what we should do to increase sales?

propose和 move 特指在会议上提出建议、提议，比较正式。而suggest指一般情况下的提建议，用的场合比较多。三者跟that从句都要用虚拟语气，即（should ）do.

proposal是一个提议，一个方案，更正式。
suggestion是意见，几句活就能说完的。 http://www.qnr.cn/waiyu/
