1.由从属连词 that，whether 引导的表语从句。
that 在引导表语从句时无词义，而 whether 有词义，意为、“是否”。这时主句的 主语常常是些抽象名词，如 question(问题)，trouble(麻烦)，problem(问题)， result(结果)，chance(可能性)，suggestion(建议)，idea(想法)，reason(理由) 等。表语从句对主句主语进行说明、解释，使主语的内容具体化。 The trouble is (that) she has lost his money. 麻烦的事是他丢了钱。 The question is whether we need more ice cream.问题是我们是否还需要一些 冰淇淋。 The problem was that it was too valuable for everyday use.问题是它作为日常 之用太贵重了。 What she couldn’t understand was that fewer and fewer students showed interest in her lessons. 我们不能理解越来越少的学生对他的课不感兴趣。
3. 由连词 because，as if/as though 等引导的表语从句。 反
It looked as if it was going to snow.看起来好像要下雪了。 That's because we never thought of it.这是因为我们从未想过此事。 It seems as if he didn’t know the answer.好像他不知道答案。

说明主语是什么或者怎么样，表语从句对主句主语进行说明、解释， 使主语的内容具体化；表语从句只能置于主句之后，而主句的动词只 能是联系动词；可以接表语从句的连系动词由 be, look, remain, seem 等。 Eg: The problem is puzzling. 这问题令人困惑 主语 连系动词 形容词作表语 The problem is when we can get a pay rise. 问题是什么时候我们可 以得到加薪. 主语 连系动词 一个句子作表语---表语从句 He has become a teacher. 他已经成为一名教师。 He has become what he wanted to be ten years ago. 他已经成为了他 10 年前想成为的。 She has remained there for an hour. 她曾在那里停留了一个小时。 She has remained where I stood yesterday for an hour. 她一直在我昨天 站的地方站一个小时。 His suggestion is good. 他的建议是好的。 His suggestion is that we should stay calm. 他的建议是，我们应该保持 冷静。 2. 连接表语从句的连接词有：
That is why she failed to pass the exam. (why 在表语从句中充当原因状 语) 那就是她考试不及格的原因。
注意：
“That is why...”是常用句型， 意为“这就是„„的原因/因此„„” ， 其中 why 引导的名词性从句在句中作表语， 该句型通常用于针对前面 已经说明过的原因进行总结， 又如： That is why you see this old woman before you know, Jeanne. (前文提到 Jeanne 对老妇人显得苍老憔悴深感 诧异， 说话人对她讲述了其中的原因之后，用这一句来进行概括)。 That is why I came. 这就是我来的原因。 下面是两个与“That is why...”形式相似的结构 (1)“That is why...”与“That is the reason why...”同义， 只不过从语法结构 上讲， “That is the reason why...”中 why 引导的是—个定语从句，将其 中的 the reason 去掉则与“That is why...”结构一样， 例如： That is (the reason) why I cannot agree. 这就是我不能同意的理由。 (2)“That is because...”句型中从属连词 because 引导的名词性从句在此 作表语， 这也是个常用句型， 意为“这就是为什么……/因为……”。 “That is because...”与“That is why...”之间的不同在于“That is because...” 指原因或理由， “That is why...”则指由于各种原因所造成的后果， 例 如：He did not see the film last night. That is because he had to help his little sister with her homework.昨天晚上他没有去看电影， 那是因为他 得帮助他的妹妹做作业。 (第一句话说明结果， 第二句话说明原因) He had seen the film before. That is why he did not see it last night. 他以前曾看过那部电影， 因此他昨天晚上没有去看。 (第一句话说明原因， 第二句话说明结果) 例题精析： ［考题 1 ］ The traditional view is ___we sleep because our brain is
