would 和used to 的区别
would意为“总是”、“往往”、“总要”、“惯于”、“就会”，是情态动词，后面接动词原形，通常表示过去经常反复发生的习惯性动作。would通常用于以下两种结构：
1、S + would + 动词原形；
2、S + wouldn't + 动词原形；
这是would的否定句，表示拒绝、无此习惯或不可能，意为“不肯”。
used to意为“过去常常”，其中to是动词不定式符号，后面接动词原形，表示过去经常性或习惯性的动作或状态现在已经结束，只能用于一般过去时，含有较强的“今昔对比”的意味。
相同点：
used to 和would 都用来表达现在已不存在的过去的习惯或状态，都不能用来表示动作发生的具体频度或发生在具体的某一段时间。
不同点：
used to可指过去的状态或情况，would则不能。
would表示反复发生的动作。如果某一动作没有反复性，就不能用 would，只能用 used to。
used to表示过去经常性或习惯性的动作或状态现在已经结束，would则表示有可能再发生。
