祈使句后接并列连词 and 或 or,再接一个陈述句,是中考英语一个十分重要的考点。本文拟对这一结构作一简要分析。
一、结构分析
结构一: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:
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。
结构二: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 well be late for school 快点,不然我们就会上学迟到。
Get up or youll be late for school 起床吧,否则你上学会迟到了。
Keep to the path or youll lose your way 沿这条小道走,否则就要迷路。
二、命题切入点
针对这种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,所以句中动词要用原形。
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,用 and;若意思不一致,则用 or。如:
Be quick,_________youll miss the early bus
A and B soC 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,否则你就赶不上早班车了”。
3 考查陈述句中的动词时态,原则上用一般将来时。如:
Be quiet or you_________the whole house!
A are wakingB have wakenC 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。
