表语从句讲解及专项练习、答案
表语从句讲解及专项操练之袁州冬雪创作概念：表语从句是在复合句中作表语的名词性从句.放在系动词之后,一般布局是“主语+系动词+表语从句”可以接表语从句的连络动词有be, look, remain, seem等.★ The trouble is that we are short of money.坚苦是我们资金短缺.★ That is why stone walls are used instead of fences around New England fields.这就是为什么在新英格兰用石头墙而不必栅栏的原因.★ At that time, it seemed as if I couldn't think of the right word anyhow.当时,我似乎怎么也想不出一个恰当的字眼来.引导表语从句的词：从属连词that、whether、as though、 as if（That引导表语从句时，在白话中，间或可以省略.）关系代词who, what, which, whom, whose, whatever, whoever, whomever, whichever等；关系副词when, where, why, how, however, whenever, wherever等.※ 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(费事)，problem(问题)，result(成果)，chance(能够性)，suggestion(建议)，idea(想法)，reason(来由)等.表语从句对主句主语停止说明、诠释，使主语的内容详细化.例如：★ The trouble is (that) she has lost his money. 费事的事是他丢了钱.★ 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 tha t fewer and fewer students showed interest in her lessons. 我们不克不及懂得越来越少的学生对他的课不感兴趣.※ 由关系代词引导的表语从句.关系代词who, what, which, whom, whose, whatever, whoever, whomever, whichever等引导表语从句，在句中作主语、宾语、表语，关系代词不克不及省略.例如：★ The question is which of us should go.问题是我们哪个应该去.★ The problem was who could do the work.问题是谁能做这项工作.★ That's what he is worrying about.那就是他在担心的事.★ That's what we should do.那是我们应该做的.※由关系副词引导的表语从句.关系副词 when, where, how, why 除在句子起毗连作用外，在从句中还充当时间，地点，方式或原因状语，自己具有词义.例如：★Go and get your coat. It's where you left it. 去把雨衣拿来.就在你原来放的地方.★ I had neither a raincoat nor an umbrella. That’s why I got wet through. 我们既没伞也没雨衣，这是我们淋湿的原因.★ That is how mice ruin many stores of grain every year.那就是老鼠是怎样每一年损害大量食粮的.★ That is what he is worri ed about.那就是他所担心的.※ 由连词because，as if/as though等引导的表语从句.★ 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.注意A. 表语从句一定要用陈述语序.False: The question is when can he arrive at the hotel.Right: The question is when he can arrive at the hotel.B. 不成以用if，而用whether 毗连表语从句(as if 破例）.引导宾语从句时可以互换if/whether 位于介词后要用whether位于句首时要用whether.引导表语从句，主语从句，同位语从句时要用whether.False: The question is if the enemy is marching towards us.Right: The question is whether the enemy is marching towards us.Right: It looked as if he had understood this question.C.不像宾语从句，在有表语从句的复合句中，主句时态和从句时态可以纷歧致.Right: The question is who will travel with me to Beijing tomorrow.Right: The question is why he cried yesterday.D. that在表语从句中不成以省掉.基本用法表语从句只能置于主句之后，而主句的动词只能是接洽动词.名词性从句在be等系动词后作表语时被称为表语从句例如：★The problem is how we can get the things we need.问题是我们怎样能弄到我们需要的东西. (how 在表语从句中充当方式状语)★ The scissors are not what I need.这把剪刀不是我所需要的.(what 在表语从句中充当宾语)★ What I told him was that I would find him a good play. 我告诉他的是我会给他找个好脚本.(what在主语从句中作直接宾语， that作为表语从句的引导词在该表语从句中不充当句子成分，不克不及省略)★ That is what I want to tell you.那就是我想要对你讲的.(what在表语从句中充当直接宾语)★ That is why she faile d to pass the exam. 那就是她测验不及格的原因.(why 在表语从句中充当原因状语)表语测试1.

※由关系副词引导的表语从句。
关系副词when, where, how, why 除在句子起连接作用外，在从句中还充当时间，地点，方式或原因状语，本身具有词义。
例如：★Go and get your coat. It's where you left it. 去把雨衣拿来。
就在你原来放的地方。
★I had neither a raincoat nor an umbrella. That’s why I got wet through. 我们既没伞也没雨衣，这是我们淋湿的原因。
★That is how mice ruin many stores of grain every year.那就是老鼠是怎样每年损害大量粮食的。
★That is what he is worried about.那就是他所担心的。
※由连词because，as if/as though等引导的表语从句。
★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。
注意A. 表语从句一定要用陈述语序。
False: The question is when can he arrive at the hotel.Right: The question is when he can arrive at the hotel.B. 不可以用if，而用whether 连接表语从句(as if 例外）。
引导宾语从句时可以互换if/whether 位于介词后要用whether位于句首时要用whether。
引导表语从句，主语从句，同位语从句时要用whether。
False: The question is if the enemy is marching towards us.Right: The question is whether the enemy is marching towards us.Right: It looked as if he had understood this question.C.不像宾语从句，在有表语从句的复合句中，主句时态和从句时态可以不一致。
Right: The question is who will travel with me to Beijing tomorrow.Right: The question is why he cried yesterday.D. that在表语从句中不可以省掉。
基本用法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。
名词性从句在be等系动词后作表语时被称为表语从句例如：★The problem is how we can get the things we need.问题是我们怎样能弄到我们需要的东西。
(how 在表语从句中充当方式状语)★The scissors are not what I need. 这把剪刀不是我所需要的。
(what 在表语从句中充当宾语)★What I told him was that I would find him a good play. 我告诉他的是我会给他找个好剧本。
(what在主语从句中作直接宾语，that 作为表语从句的引导词在该表语从句中不充当句子成分，不能省略) ★That is what I want to tell you.那就是我想要对你讲的。
(what在表语从句中充当直接宾语)★That is why she failed to pass the exam. 那就是她考试不及格的原因。
