used to用法详解

1、其基本义为“过去常常”，注意以下用法：

（1）一般不能与表示次数（如twice，three times等）或一段时间（如three months，five years等）的词语连用，但可与always，often，sometimes，never等频度副词连用。

（2）构成否定式和疑问式时有两种形式：借助助动词did（较口语化）或直接将used用作助动词（较正式）。

2、used to与would的区别

（1）两者均可表示过去习惯性的动作，有时可互换。如：

When we were children we would go skating every winter. 我们小时候，每年冬天都去溜冰。

（2）当要表示过去持续的状态或表示过去与现在的对比（即“以前这样，但现在不这样了”）时，则要用used to。
