演讲要点:介词短语作状语总结、否定副词引导倒装总结、虚拟条件句倒装总结
行文逻辑:分析倒装结构→列举典型例句→归纳使用规则
一、介词短语作状语位于句首,谓语动词是不及物动词时,句子要完全倒装。
例:in the front of the lecture hall sat the speaker.
二、here, there,now, then开头的句子,句中的谓语动词为不及物动词时,句子要发生完全倒装。
例:here comes the train! / there goes the bell!
三、表否定的副词或短语位于句首,句子要发生部分倒装。
常见否定副词:not , not only , few, barely, never , little , seldom , hardly, scarcely, ...
常见表否定的短语:in no way, by no means, at no time, under no circumstance...
例:little do they know about him.
seldom does she come back on sundays.
注:not only ... but also ... 引导两个并列句,前倒后不倒。
例:not only does she do well in her lessons, but also she often helps others with their lessons.
四、only+状语(从句)位于句首时,主句要部分倒装。
例:only then did i realize the importance of english.
五、so…that结构中的倒装。
如果要强调so 所修饰的形容词或副词,常将so及它所修饰的形容词或副词一起提到句首。这时,主句要发生部分倒装。
例:倒装前:she runs so fast that she is far ahead of others.
倒装后:so fast does she run that she is far ahead of others.
六、 if 引导的虚拟条件句中,如有 were ( had , should ) , if 则可省去,,把were,had,should提到主语前面,发生部分倒装。
例:倒装前if we had come yesterday, we would have seen him.
倒装后had we come yesterday, we would have seen him.
七、as 引导的让步状语从句,要发生部分倒装。
1. 副词置于句首。
例:much as she like it (=although she like it very much), i will not buy it.
2. 动词置于句首。
例:wait as we may (= although we may wait), he will not see us.
3. 形容词或名词置于句首。
例:child as he is (=although he is a child), he can tell right from wrong.
注:当名词前有形容词修饰时,as引导的倒装句中要保留不定冠词。
例:a bad-tempered man as he is (=although he is a bad-tempered man), he loves me deeply.
