Predicative Clauses (表语从句)
表语从句的用法
在复合句中用作表语的从句是表语从句, 引导表语从句的关联词与引导主语从句 的关联词大致一样, 表语从句位于连系动 词后, 有时用as if 引导。其基本结构为:主 语 +系动词 + that 从句。 That’s what we should do. That’s why I want to see you.

【解析】 考查名词性从句。所填词引导
if和whether引导动词后的宾语从句时一 般可通用，但介词后的宾语从句、主语从 句(放在句首时)、表语从句常由whether引 导。例如:
Whether she will go home or not is unknown.
It remains to be decided whether / if we shall raise ducks or geese.
Attention
在表语从句中, 当 reason 做主语时,引导 词只能用that, 不能用because。 如: 他迟到的原因是因为他没有赶上早班车。 The reason why he was late was that he didn’t catch the early bus.
主语从句的用法 一、主语从句在句中作主语, 主语从句
(4) It is＋过去分词＋从句 It is reported that… 据报道…… It has been proved that… 已证实…… It is said that… 据说……
三、It 作形式主语和 it 引导强调句的比较 It 作形式主语代替主语从句, 主要是为了平 衡句子结构, 主语从句的连接词有变化。而it 引导的强调句则是对句子某一部分进行强调, 无论强调的是什么成分, 都可用连词that。被 强调部分指人时也可用who/whom。例如:
例如:
（1）What we can’t get seems better than what we have.
（2）That we should work out a plan to deal with the serious situation is important.
2)引导词if和whether
2. as if, because 也可引导表语从句。 如： It looks as if it’s going to rain. It was because I got up late. 3. 在非正式文体中, 引导表语从句的that 可以省略。如: The trouble is (that) he is ill.
The reason for my absence was that I was ill. 1. be, seem, look等动词后均可跟表语从 句： 如：My suggestion is that we should go shopping. It seems that it is going to rain.
可以位于句首, 但常见的主语从句多 放在句末, 句首则用形式主语 it。
1. That the earth is round is true. = It is true that the earth is round.
2. Whether he will come hasn’t been decided. = It hasn’t been decided whether he will come. Attention: 连词that, whether在从句中不担任句子成 分, 只起连接作用, 不能省略(注：if 不可用 来引导主语从句)。
It is a pity that you didn’t go to see the film. It doesn’t interest me whether you succeed or not. It is in the morning that the murder took place. It is John that broke the window.
