“祈使句+and+陈述句”句型

2006年普通高等学校招生全国统一考试(重庆卷)中有这样一道单项选择题:___________ and I’ll get the work finished.A.Have one more hour B.One more hour C.Given one more hour D.If I have one more hour 解析:从句子结构上看,and连接了两个分句,两句间存在着一种顺承关系,其中前一分句表示一种条件或假设,相当于if条件状语从句,后一分句表示一种结果或推论。换句话说,本题考查的是“祈使句+and+陈述句”句型,其中祈使句可转换成名词短语,故答案为B。该句型不仅是高考的一个考点,也在中学课本中频频出现。现将这一句型需要注意的问题及其变体形式简要介绍一下。一、句型中陈述句的时态或语气决定着祈使句表示的条件性质 1. 当陈述句是一般将来时或一般现在时的时候,祈使句是真实条件句。例如:Follow the advice of the doctor, and you’ll be well very soon.解析:陈述句谓语部分为一般将来时,所以祈使句表示真实条件句(If you follow the advice of the doctor)。Work hard, and you can make rapid progress in your study.解析:陈述句谓语部分为一般现在时,所以祈使句表示真实条件句(If you work hard)。2. 当陈述句的谓语动词是would /should / could / might + 动词原形或完成体时,祈使句表示非真实条件句。例如:Pass my house and you might return the book you borrowed.解析:陈述句谓语部分为might return,所以祈使句表示非真实条件句(If you should pass my house)。Come tomorrow and I would tell you everything.解析:陈述句谓语部分为would tell,所以祈使句表示非真实条件句(If you should come tomorrow)。二、“祈使句+ and + 陈述句”句型的三种变化形式1.“祈使句+ 破折号+ 陈述句”Try some of this juice—perhaps you’ll like it. (2000年京皖春招)尝尝这种果汁,也许你会喜欢的。2.“名词词组+ and + 陈述句”名词词组中通常含有more, another, further, earlier等词。It is really very dangerous.One more step, and the baby will fall into the well .真危险。再多迈一步,这个小孩儿就掉进井里了。Another £500, and I could buy a car.假如我再有500镑,就能买辆小汽车了。One step further and you’ll lost.再多走一步,你就会迷失方向了。A few minutes earlier, and I could have seen the famous scientist.要是我早来几分钟,就能见到那位著名的科学家了。3.“祈使句+ or + 陈述句”or表示“否则”、“要不然的话”,or可用or else或otherwise替换,从反面来预测结果。Take the chance, or you will regret it. 抓住机会吧,否则你会遗憾的。Watch your step, or else you might fall into the water.留神脚下,不然你会掉进水里的。Do as you’re told, otherwise you’ll be in trouble.叫你怎么做就怎么做,否则你会有麻烦的。高考链接:1.Start out right away,__________ you’ll miss the first train.
