先来一张思维导图：
下面是wait的短语：
（1）wait for sb./sth./时间段 “等候……”,for是介词。
wait for me 等我
wait for a bus等公交车
wait for about twenty minutes 等了大约20分钟
(2) wait 时间段 for sb./sth.
wait a long time for the train（人教版八上Unit 1)等火车等了很久
下面的用法更常见：
wait for sb./sth. for 时间段
Yesterday I waited for my sister for over an hour.昨天，我等我妹妹等了一个多小时。
(3) wait for sb.to do 等某人做某事
He is waiting for me to go to the store together.他正在等我一起去商店。
(4) can't/could't wait to do 迫不及待地做某事，等不及去做某事
He could't wait to open the door.
他迫不及待地打开门。
(5) wait a minute 等一会儿
wait a moment 等一会儿
just a moment 请稍等
欢迎各位提宝贵意见，不要客气哦[比心]
