两个十分重要的并列句结构

 一、句型分析

句型一  祈使句,+and + 陈述句

该句型表示如果做到了祈使句表示的事情,就会有后面句子表示的结果。如:

Be quiet, or he will hear us. 安静,不然他们会听见我们的。

Work hard, and you will pass the exams. 努力学习,你就会通过考试。

Come early, and you will see the film star. 早点来,你就可以看到这位电影明星。

句型二  祈使句,+ or + 陈述句

该句型表示如果不做到祈使句表示的事情,就会有后面句子表示的结果。如:

Hurry up, or we’ll be late for school. 快点,不然我们就会是上学迟到。

Get up or you’ll be late for school. 起床吧,否则你上学会迟到了。

Keep to the path or you’ll lose your way. 沿这条小道走,否则就要迷路。

二、命题切入点

针对这句型最可能的命题切入点有三个方面:

1. 考查祈使句句首的动词形式。祈使句句首用动词原形。如:

Just ______ to him, and you will see how clever he is!

A. to listen             B. listen                 C. listened            D. listening

【答案与解析】答案选B。因为是祈使句,所以句首要用动词原形。

2. 考查连词and与or的选择与辨析。看前后意思是否一致,若意思一致,则用and;若意思不一致,则用or。如:

Be quick, ______ you’ll miss the early bus.

A. and            B. so                  C. but               D. or

【答案与解析】答案选D。因为前后意思不一致,句意为“快点,否则你就赶上不早班车了”。

3. 考查陈述句中的动词时态。原则上用一般将来时。如:

8. Be quiet or you______ the whole house!

A. are waking       B. have waken     C. will wake          D. wake

【答案与解析】答案选C。因其中的陈述句表示将来意义,故用一般将来时。
