英语中的缩略形式主要是人称代词的主格形式（I / you / he / she / it / we / you / they）和疑问词（what / where/ who）与系动词（am/is/are）、助动词（has/had/will/would），系动词、助动词和情态动词与not等词缩略而成。
缩写形式主要有以下几种形式：
1.人称代词主格与系动词的缩写：
❶ I'm = I am 我是❷ we're = we are 我们是
❸ you're = you are 你(们)是❹ she's = she is/was 她是❺ he's = he is/was 他是❻ it's = it is/was 它是❼ they're = they are 他(她，它)们是
2. 否定句中系动词与not的缩写：❶ isn't = is not 不是❷ aren't = are not 不是
❸ wasn't = was not 不是
❹ weren't = were not 不是
3. 人称代词主格与shall/will，not的缩写：

使用缩写形式时应注意以下几点：
1. this is 没有缩略形式；
2. 第三人称单数与“'s”的缩写中，"'s"可以表示三个词：is，was，has。如：she is, she was，she has的缩写形式都是she's 。同学们在使用时一定要根据时态和语境具体情况具体分析，做到心中有数， 不能想当然的认为是"'s"就是 is；
3. 对一般疑问句进行简单回答时，肯定形式不能用缩略形式。
