英语学习者一定对这几组动词短语used to, be used to do, be used to doing, 又爱又恨, 特别容易记混，今天我们两种方法让你彻底分清楚，一种方法我们通过联想记忆，另外一种就是在网上找到一首英语歌曲，我们边唱边学习used to。
联想记忆：无be,used to 中used 是过去式，used to 类比情态动词后面接动词原形。
I used to take exercise in the morning.
我过去常常早上锻炼。
联想记忆：be done 构成被动语态， be used 是被用来，“去做某事”是“to do”.

笔是被用来写字的。
联想记忆：be +used（adj. 习惯的）+to(介词)+doing
