1、陈述句的否定
(1)在含有宾语从句的主从复合句中,当主句的谓语动词是think, expect, believe, suppose, guess, fancy,imagine等,且主句主语是第一人称时,宾语从句谓语的否定习惯上要移到主句谓语上,如: I don't think he is right.

(2)含有否定意义的副词never, seldom, hardly, scarcely, rarely, barely的句子应视为否定句,如: I have never been there before.

2、反意疑问句

(1)need和dare 既可作情态动词,又可作实意动词,在反问部分须加以区别,如We needn't leave, need we? We don't need to leave, do we?

(2)陈述部分出现否定意义的副词或代词如never, seldom, few, hardly, little等时,反问部分须用肯定形式,如:He seldom comes, does he?

(3)陈述部分用不定代词作主语时,反问部分的主语用it ,如:Nothing can stop me, can it?

陈述部分用everybody, everyone, somebody, someone,等作主语时,反问部分常用it,有时也用they,如:Everybody knows that, don't they?

(4)陈述部分包括used to 时,反问部分可有两种形式,如: You used to get up early, usedn't (didn't) you?

(5)陈述部分是"there + be"结构时,反问部分用there,如:There's something wrong with you, isn't there?

(6)陈述部分是含有宾语从句的主从复合句时,反问部分的主语和谓语应和主句保持一致,如: He never told others what he thought, did he?

但,如果是I think , I believe等+宾语从句时,反问部分须和从句的动词保持一致,如,I don't think he is right, is he? I don't believe he does that, does he?

主语从句
作句子主语的从句叫主语从句。主语从句通常由从属连词 that , whether ,if 和连接代词 what , who , which , whatever , whoever 以及连接副词 how , when , where , why 等词引导。 that 在句中无词义,只起连接作用;连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用,在从句中充当从句的成分。

有时为避免句子头重脚轻,常用形式主语 it 代替主语从句作形式主语放于句首,而把主语从句置于句末。主语从句后的谓语动词一般用单数形式。常用句型如下:

( 1 ) It + be + 名词 + that 从句

( 2 ) It + be + 形容词 + that 从句

( 3 ) It + be + 动词的过去分词 + that 从句

( 4 ) It + 不及物动词 + that 从句

另注意在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时,谓语动词要用虚拟语气“ (should) +do ”,常用的句型有:

It is necessary (important, natural, strange, etc.) that …

It is a pity (a shame, no wonder, etc.) that …

It is suggested (requested, proposed, desired, etc.) that …
