兩個十分重要的并列句結構

■湖南  劉  亞

一、句型分析

句型一  祈使句，+and + 陳述句

該句型表示如果做到了祈使句表示的事情，就會有后面句子表示的結果。如：

Be quiet, or he will hear us. 安靜，不然他們會聽見我們的。

Work hard, and you will pass the exams. 努力學習，你就會通過考試。

Come early, and you will see the film star. 早點來，你就可以看到這位電影明星。

句型二  祈使句，+ or + 陳述句

該句型表示如果不做到祈使句表示的事情，就會有后面句子表示的結果。如：

Hurry up, or we’ll be late for school. 快點，不然我們就會是上學遲到。

Get up or you’ll be late for school. 起床吧，否則你上學會遲到了。

Keep to the path or you’ll lose your way. 沿這條小道走，否則就要迷路。

二、命題切入點

針對這句型最可能的命題切入點有三個方面：

1. 考查祈使句句首的動詞形式。祈使句句首用動詞原形。如：

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

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

【答案與解析】答案選B。因為是祈使句，所以句首要用動詞原形。

2. 考查連詞and與or的選擇與辨析。看前后意思是否一致，若意思一致，則用and；若意思不一致，則用or。如：

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

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

【答案與解析】答案選D。因為前后意思不一致，句意為“快點，否則你就趕上不早班車了”。

3. 考查陳述句中的動詞時態。原則上用一般將來時。如：

8. Be quiet or you______ the whole house!

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

【答案與解析】答案選C。因其中的陳述句表示將來意義，故用一般將來時。
