英语中的并列句有两种情况：完全并列句,即两个有着各自主谓（宾）完整结构的的并列句,和同一主语的不完全并列句.前者实际上是两个完全独立的两个句子,因语义表达需要而组合在一起.此类并列句不能省主语；后者实际上是并列谓（宾）语结构,多见于祈使句和同一主语的不同行为或状态的描述.例：
完全并列句：John went to school but Jane stayed at home yesterday.
不完全并列句：
1. （You）come to school early, gather together with your fellow students in the hallway, keep quiet and wait for the teacher to come.（祈使句——命令或指导性句子）
2. In order to be successful in the final exam, students will work really hard on the subjects, take shorter breaks, and leave for home later than usual.（同一主语不同谓（宾）语结构）
