1、辨别 that 引导的从句类型怎样区分 that 引导的定语从句、同位语从句、主语从句和强调结构呢？可采用“成分法” “试加法” “试减法” “还原法” 。现分述如下：（1）定语从句可用“成分法”即分析 that 引导的从句的句子成分，如果 that 在从句中充当主语或宾语，则此从句为定语从句。The matter that you were arguing about last night has been settled.你们昨天晚上讨论的那个问题已经解决了。A plane is a machine that can fly.飞机就是可以飞的机器。（2）同位语从句可用“试加法” ，即在名词
2、和从句之间加系动词 be，使该名词和从句构成一个新的句子。如果句子通顺、合乎逻辑，那么从句就是同位语从句。We heard the news that our team had won. 我们听说了我们队取胜的消息。The fact that he had not said anything surprised everybody.他什么也没有说，这使每个人都吃了一惊。根据“试加法” ，句可改写为：The news was that our team had won.句可改写为：The fact was that he had not said anything.改写后的句子 、通顺，合乎逻辑
3、，故 that 引导的从句为同位语从句。（3）用 it 作形式主语的主语从句可用“还原法” ，即把 that 引导的从句调到句首，去掉句首的 it，再加句子剩余部分。如新句子意思不变，合乎逻辑，则该从句为主语从句，否则为其它从句。Its a rule that he gets up at six oclock every morning.他每天早上六点起床，这是一个规律。Its clear that he has finished his homework. 很明显，他已经完成了作业。按“还原法” ，句可构成新的句子：That he gets up at six oclock every mo
4、rning is a rule.句 可构成新的句子： That he has finished his homework is clear.句子、改写后意思通顺、合乎逻辑，故 that 从句为主语从句。（4）强调结构采用“试减法” ，即把句子中的“It bethat”这一框架去掉，如果句子剩余部分（可以做位置上的调整）意思通顺，合乎逻辑，则 that 是强调结构的标志。It was five years ago that he joined the party. 他就是五年前参军的。It is you that are wrong. 错的就是你。根据“试减法”句可改成新句子：He joined
5、 the party five years ago.句改为：You are wrong 改写后的句子通顺，合乎逻辑，故句、为强调句型。Exercises:1The news to Shanghai delighted all of them.A. they would go B. which they would goC. that they would go D. would go2I have read all the books you gave me.A. one B. that C. what D. it3 is a fact that English is being accept
