关于used to 的用法
我看过好些句子.有的是主语后面直接加used to,例如:he used to get up early.
但有些句子主语与used to 之间又加有be动词,例如:I am used to eat dinner with my family every day.
这两种用法到底有什么区别?

used to是过去常常,后面加do
be used to 是习惯于做某事 后面加doing。所以你那个句子错了,应该是I am used to eating dinner with my family every day.
如果你是填空的话,就看后面的动词有没有加ing,加了就是be used to ,没加就是used to。
这是初三的语法吧,好好记着,

used to do 表示过去做某事而现在不做了
be used to +n/doing 习惯于某事或做某事

used to do sth 过去常常做某事 he used to get up early他过去常常早起be used to doing sth 习惯于做某事 I am used to eating dinner with my family every day.我习惯于每天和家人一起吃晚饭be used to do被用于...

used to 是表示过去常常做某事
be used to 是表示经常习惯做某事
