instead of:代替

I went to the bar to wait for the food,我到酒吧等餐

wait for:等候； 等待

她没有耐心等公共汽车到来。

词义辨析:wait, await这两个词都有“等待”的意思,其区别是：

1.await是正式用词,常用于书面语,不如wait常用。

2.await后面可以接动名词作宾语,但不可接不定式, wait后面可以接不定式作状语,但不可接动名词,如：I shall await hearing from you和I shall wait to hear from you。这两句里的await和wait不可对调。

3.await, wait for这二者含义相同,但wait for后面接了宾语还可以加上不定式,而await却不可,如

I am waiting for him to come(我在等着他来。)里的waiting for不可改作awaiting。
