定语从句中,常用that的情况
that是个常见词,用法广泛.作为连词,它可以引导不同种类的从句.现就此探讨归纳如下：
一、that引导名词性从句
所谓名词性从句,指的是主语从句、宾语从句、表语从句和同位语从句.that引导名词性从句时,它本身不作任何句子成分,也没有任何词义,只起连接作用.
1.that引导主语从句
可以将that引导的主语从句放在谓语动词前面,也可在句首用形式主语it,而将that引导的主语从句后置.例如：
（1）That Mr King had been put into a women”s ward surprised his boss .
= It surprised his boss that Mr King had been put into the women”s ward .
金先生被安排在了女病房使他的老板很吃惊.
（2）That Professor Wang will give us a lecture tomorrow afternoon is known to all .
= It is known to all that Professor Wang will give us a lecture tomorrow afternoon .
大家都知道,王教授明天下午要给我们讲课.
注意：that常在下边的句型中引导主语从句：It is / was + 动词的过去分词 + that从句.例如：
（3）It is said that the book has been translated into several foreign languages .
据说,那本书已被译成了几种外语.
（4）It is reported that as many as 250,000 people lost their homes because of the earthquake .
据报道,多达25万人因地震而无家可归.
2.that引导宾语从句
引导宾语从句的that,在口语和非正式语体中常可省略.如果句中有两个或两个以上的宾语从句,则除第一个that可省略外,其它宾语从句中的that都不能省略.例如：
（1）He suggested (that) we should keep on trying .
他建议我们继续努力.
（2）We must believe (that) each one of us is able to do something well ,and that ,when we discovered what this is ,we must work hard at it until we succeed .
我们必须相信,我们每个人都能把每件事做好；而且我们领悟此事是何事之后,我们就必须努力做下去,直到成功为止.
3.that 引导表语从句
that引导的表语从句,一般位于句尾,that通常不能省略.例如：
（1）It seems that it is more difficult for women to get jobs than men .
似乎女人找工作比男人更难.
（2）The reason why so many people were killed in the big fire is that the building was built without any fire escapes .
这么多的人在大火中丧生,其原因是那座楼房里没有太平门.
4.that引导同位语从句
同位语从句是对前面名词的具体内容所作的详细阐述.例如：
（1）We are surprised at the fact that the children did it on their own .
听说孩子们独立做那件事,我们感到吃惊.
（2）They expressed their hope that they would like to go to visit the Great Wall .
他们表达了他们想去参观长城的愿望.
二、that引导定语从句
that引导定语从句时,是关系代词,它可指人（相当于who ,whom ）,也可指物（相当于which）.that在定语从句中可作主语,也可作宾语（作宾语时常可省略）.当定语从句修饰的先行词既有人又有物时,只能用that引导定语从句.例如：
1.This is the museum (that / which) they visited last month .
这就是他们上个月参观的博物馆.
2.They are going to the village that / which lies south of the mountain .
他们将去山南边的那个村庄.
3.The man (that / who / whom) I shook hands with just now is one of my old classmates .
刚才和我握手的人是我过去的一位同班同学.
4.Do you still remember the things and persons that we talked about at the meeting last month
你还记得上月我们在会上谈到的人和事吗?
三、that用在强调句型中
强调句型的结构为：It is / was … that … .如果被强调的是人,可用who代替that.如果被强调的是时间状语、地点状语或原因状语,则一般都用that.例如：
1.It was on July 30 that they decided to meet again .
就是在六月三十日他们才决定再一次见面的.
2.It is in the classroom that we usually have our classes .
我们通常是在教室里上课.
3.It was Ms King who / that pretended to be a man in order to get a job .
为找工作而女扮男装的是金女士.
