used to用法You're doing in a wrong way!It ------ this way.A.us

应该选C.意思是,“你的做法是错的.过去是这么做的.”
在英语里这是一个考点---used to so sth..
因为常常与be used to doing sth.（习惯作某事）混淆,所以经常两个一起考.
两者用法如下：
1、used to do sth. 过去常常做某事,现在不了.
肯定：I used to get up early.
否定：I didn't use to get up early.
疑问：Did you use to get up early?
2、be used to doing something
肯定：I am used to eating school food now.
否定：I'm not used to eating the food now.
疑问：Are you used to eating the food now?
