wait的用法簡述如下：
一、wait可單獨使用.例如：
Wait till the bus stops before getting off．等公共汽車停了再下車.
I can wait if you can't get there on time．如果你不能按時到這里,我可以等.
二、wait后接表示所等的人、物的名詞或代詞時,應與介詞for連用.例如：
She is waiting for her mother．她正在等她媽媽.
They are waiting for the train．他們正在等火車.
三、wait后接表示目的的動詞不定式.例如：
They are waiting to have dinner．他們正等著吃飯.
We are waiting to go there．我們等著去那里.
四、如果表示“等某人（物）進行某動作”,wait后不能接賓語從句,而應用wait for sb．（sth．）to do結構.例如：
Are you waiting for me to give back the book?你在等我還書嗎?
The students are sitting quietly in the classroom and waiting for their new teacher to come in．學生們靜靜地坐在教室里,等候新老師的到來.
五、wait習慣上后接“and＋另一動詞”,而不直接接動詞不定式.例如：
Let's wait and see．讓我們等著瞧.
