点拨名词性that从句的难点分析

1、【奇速英语】点拨名词性that从句的难点名词性从句，指的是在句法上所起的作用与名词所起的作用相同的那些从 句，它包括主语从句、宾语从句、表语从句和同位语从句。能引导名词性从句的 引导词很多，但用得最多，且能同时引导这四类名词性从句的首选 that从句。同 学们在使用名词性that从句时，应特别注意以下几点：一、名词性that从句的功能特点that只起连接主句和从句的作用，在从句中不担任任何成分，本身也没有词义。 名词性that从句在句中能充当主语、宾语、表语、同位语等。如：That he will come is certain.他将来，这是肯定无疑的。（that从句用作主语）I notice

2、d that he spoke En glish fluen tly.我注意到他说英语很流利。（that从句用作 宾语）The problem is that we have n' t got eno ugh n问题就是我们还没有足够多的钱。（that从句用作表语）The fact that he loves Mary is clear to everyone.他喜欢玛丽这一事实是人人都清 楚的。（that从句用作同位语）二、名词性that从句用作介词宾语在一般情况下，名词性that从句不能用作介词的宾语，如不能说：They were worried over that you wer

3、e sick.误）He must face up to that he is no Ion ger youn g.误）There ' s no getting away from that the country' s economy is suffering.(关于这一问题，请注意以下几点：1. that引导的宾语从句一般不用作介词宾语，但可用于介词except, but, in等少数几个介词的宾语。如：The film is very good except that the ending is a little sad.这部电影很不错， 只是结 尾有点让人伤心。But t

4、hat he has a family, he would have left here long ago 要不是他有一个家，他老早就会离开英国了。2. 除except, but, in等几少数几个介词外，其他介词后若要接that从句作宾语，则通常在介词后先接名词the fact作宾语，然后再后接that从句用作the fact的 同位语。如上面的几个误可分别改为：They were worried over the fact that you were sick.他们为你生病发愁。He must face up to the fact that he is no Ion ger young.

5、他应该勇于正视自己不再年轻这一事实。There ' s no getting away from the fact that the country' s econ国my is suffering.经济疲软，这一事实无法回避。3. 在少数情况下，介词后接that从句作宾语时，可采用 介词+it +that从句”这样 的结构，it被看作是that的先行词。如：You may depe nd on it that tomorrow will be fine.你可以指望明天天晴。See to it that everyth ing is ready in time.务必要把一切都及时

6、准备好。注：有时还可以用于 动词+it+that从句”这样的结构。如：I take it that they will succeed.我认为他会成功。三、引导词that的省略情况that引导名词性从句时，是连接词，本身没有意义，也不作任何句子成分，引导 宾语从句时可以省略，不过引导主语从句、表语从句和同位语从句时一般不省略。 但是请注意以下几种情况：1. 由that引导的主语从句放在句首时，that不省略。但是，当主语从句位于句尾， 而用it来做它的形式主语时，that是可以省略的。如人教社高二英语（下册）就有 这样一句：It ' s a pity you missed the sp

7、orts meeting last we你错过了上周的运动会， 真是遗 憾。2. 引导表语从句的that通常不省略，但在非正式语体中有时也可以省略。如人 教社初中英语第三册就有这么一例：The only problem is you can ' t ealtre的问题是，你不能吃树子。3. 在通常情况下，引导宾语从句的 that是可以省略的，但也并不是说它在任何 情况下都可以省略。如以下各例中的that就不宜省略：Everybody could see what happe ned and that Tom was frighte ned. （anc连接两个名词性从句，that从句放在

8、and后面时，that不能省略）I kn ow nothi ng about him except that he is a stude nt.（that 引导的宾语从句做介词宾 语时，that不能省略）We all thought it a pity that the conference should have been called off.如果宾语从句有补足语，用it作形式宾语时，that不省略）He judged that, because he was a child, he did not un dersta nd win eS（that 从句和主句谓语动词之间或从句主语之间有插

9、入语时，that不可省略）四、that引导同位语从句和引导定语从句时的区别1. 从句法功能上来看：同位语从句中连接词that在从句中不作句子成分，也没有词汇含义，只起连接作用，其作用大致相当于一个冒号；而引导定语从句的that是关系代词，且在句中充当句子的成分（主语或宾语）。如：I hold the belief that where there is a will, there is a way. （tha引 导的是同位语从句， 它在从句中不充当句子成分）The letter that I received yesterday was from my sister. （tha引 导的是定语从

10、句，它在从句中充当宾语）2. 从意义上来看：同位语从句所表达的内容与作为中心词的名词所表达的内容是一样的，两者之间可以划等号；而定语从句则是限制或修饰中心词的，中心词所表达的内容不等于定语从句所表达的内容。如：He told me the news that his uncle would come home from abroad on National Day.(that引导的是同位语从句，其中 the news = his uncle would come home from abroad on Natio nal Day)This is the factory that we visited last mon th. (that 引导的是定语从句，其中thefactory 工 we visited last mon th.)3. 从中心名词上来看：同位语从句中的中心名词常是一些表示概括意义的抽象名词，这类名词有 fact, idea, view, thought, order, suggestion, news, truth, hope, promise, answer, belief, condition, doubt, fear,
