英語中的并列句有兩種情況：完全并列句,即兩個有著各自主謂（賓）完整結(jié)構(gòu)的的并列句,和同一主語的不完全并列句.前者實際上是兩個完全獨立的兩個句子,因語義表達需要而組合在一起.此類并列句不能省主語；后者實際上是并列謂（賓）語結(jié)構(gòu),多見于祈使句和同一主語的不同行為或狀態(tài)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——命令或指導(dǎo)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.（同一主語不同謂（賓）語結(jié)構(gòu)）
