3) suggest sb/one"s doing sth 建議某人做某事

4) suggest + that從句 建議...

此時要求that從句使用虛擬語氣，即從句的謂語由“(should) + 動詞原形”構成，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 (表示此意思的時候，一般只考查這一個用法)

其賓語從句不能使用虛擬語氣，而是使用陳述語氣，即該用什麼時態就用什麼時態，只是要注意和主句suggest的時態對應即可。

如：His words suggested (that) he was unhappy.
