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。

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。
