高中英语名词性从句详细讲解
注意
主语从句中的“主谓一致”：
1.主语从句通常被看作一个整体,主句的谓语动词用单数 形式.
is That they will come _______certain.
2. What 引导主语从句时,主句谓语动词的单复数由 表语的单复数决定.
are What he wants ______these books. is What he wants ______some water.
我认为他不会来这里. I think he won’t come here. I don’t think he will come here.
( (
) )
注意宾语从句中的时态呼应，当主 句动词是现在时，从句根据自身的句 子情况，而使用不同时态。例如： I know (that) he studies English every day. I know (that) he studied English last term. I know (that) he will study English next year. I know (that) he has studied English since 1998.
3. I
am afraid (that) I’ve made a mistake.
(作形容词的宾语)

语从句要用that引导而不是because。 The reason why he was late was that he missed the train by one minute this morning .
同位语从句
在句中起同位语的作用.一般放在名词fact , news , idea , promise, thought , suggestion, belief, truth 等之 后,用以说明或解释前面的名词.引导词有连词 that(不能省)；少数情况下也可用连接副词等.
1.The thought that we might succeed excited us. 2.The idea that they should try a second time is worth considering. 3.The suggestion that the plan (should) be delayed will be discussed tomorrow.
4.It + 不及物动词 ＋ that从句

虚拟语气 “(should) +do”，常用 的句型有： It is necessary (important, natural, strange…) that … It is a pity/ a shame/no wonder that … It is suggested (requested, proposed, desired...) that…
whatever, who, whoever, whom, whomever, whose, which, whichever 连接副词：when, where, how, why, whenever, wherever, however 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

1) 由疑问词引导的从句中, 词序按陈述句 顺序排列。
e.g. I wonder what he is doing. 注意：I wonder what was wrong /the matter

4) That在其他名词性从句中均不可省略，只有 在宾语从句中that有时可以省略，但在并列 的宾语从句中第二个that 不可省略。
e.g. He said (that) he would leave and that he would never come back again.
5) 否定的转移 若主句谓语动词为think, consider, suppose, believe, expect, fancy, guess, 等, 其后的宾语 从句若含有否定意义, 一般要把否定词转移到 主句谓语上, 从句谓语用肯定式。 e.g. I /we don’t think this dress fits you Well, does it?
3. 连接代词: what, whatever, who, whoever, whom,whose, which（哪个）： 不仅起到连接一个句子的作用,同时也是从句 的一个组成部分；从句不完整，缺成份。
