1. vt. 建議/提議
1) suggest sth (to sb) (向某人)建議某事
如：I'll suggest a new plan (to him).
2) suggest doing sth 建議做某事
如：He suggested going fishing this afternoon.
3) suggest sb/one's doing sth 建議某人做某事
如：You should suggest him/his giving up smoking.
4) suggest + that從句 建議...
此時(shí)要求that從句使用虛擬語氣，即從句的謂語由“(should) + 動(dòng)詞原形”構(gòu)成，且should可以省略。
如：He suggested (that) she (should) go to Beijing right away.
2. Vt.暗示/表明
suggest + that從句 (表示此意思的時(shí)候，一般只考查這一個(gè)用法)
其賓語從句不能使用虛擬語氣，而是使用陳述語氣，即該用什么時(shí)態(tài)就用什么時(shí)態(tài)，只是要注意和主句suggest的時(shí)態(tài)對(duì)應(yīng)即可。
如：His words suggested (that) he was unhappy.
