1704791663 英文疑难详解 93.would 和 used to 的分别
1704791664
1704791665 英文的助动词 would 和 used to,同为表达过去的习惯,但不知在用法上二者有何分别?
1704791666
1704791667 【解答】英文表示现在的习惯,多用动词的现在时态( Present Tense)或是助动词的 will;表示过去的习惯,则用 used to 或 will 的过去式 would.常与 will,would 同用的,是 often,sometimes 等副词。至于表示过去习惯的 used to 和 would,在用法上到底有何分别呢?有人说 would 是表示不规则的习惯,used to 是表示规则的习惯,但什么情形是有规则的,什么情形就是不规则,实在没有具体的标准,因为既然称为习惯,就多少是有规则的了。
1704791668
1704791669 最明确的分别,也许是这样的:would 表示一种“回想的心情”,used to 表示“过去与现在的对比”。
