2.suggest 及物動詞 ， 建議它所表示的含義是“建議或者提議”。
suggest 疑問詞 to do
suggest that sb. (should) do(含其他名詞性從句都用虛擬語氣)
suggest doing sth./ sth.
例句：
Did he suggest anything to the boss?
他給老板提建議了嗎？
May I suggest a white wine with this dish, Sir?
先生，吃這道菜，我給您推薦一種白葡萄酒，好嗎？
I suggested going home. 我建議回家。

我提議坐我的車去。

I suggest we go out to eat.
我提議我們出去吃吧。
He suggested us going out for a walk. 他建議我們出去走走。
（此句也可以改為 He suggested our going out for a walk.這里的 one doing 或 one's doing 稱做動名詞的復合結構，其中的代詞 one 或 one's 是動名詞的邏輯主語。suggest sb doing sth 固定搭配”是完全正確的）
用名詞作賓語，構成 suggest sth. for sb. to do, 表示建議某事讓某人去做。
He suggested a plan for us to draw up 他提出一個計劃讓我們去制定。
由此強調說明“ suggest sb to do sth 后面的作賓補”是錯誤的說法。
小結：suggest是及物動詞，常作“提議、建議”講。后接名詞、動名詞、含疑問詞的不定式短語或從句，從句要用虛擬語氣，但不能接不定式和復合賓語。suggest 還有“ 暗示、表明、說、指出（一個事實）” 的意思。此時從句中用陳述語氣，不用虛擬語氣。不再舉例說明。
第一、vt.建議/提議
①suggest sth (to sb) （向某人）建議某事
②suggest doing sth 建議做某事
③suggest sb/one's doing sth 建議某人做某事
④suggest that從句 建議…（其他各名詞性從句的謂語由“(should) 動詞原形”構成，should可以省略。）
第二、Vt.暗示/表明
suggest that從句（使用陳述語氣）
