如题所述
【导读】公共英语考试想必大家对此考试一定不陌生吧,如今公共英语的用处非常广泛重要,公务员考试英语免考,自考,成人高考升专科,升本科英语也免考,公共英语考试分为笔试和口试,为了帮助大家都能顺利通过考试,下面是小编为大家整理的“公共英语考试必考语法考点:名词性从句”相关内容,希望对大家有所帮助。
名词性从句用法及示例:
1.引导名词性从句的连接词
引导名词性从句的连接词可分为三类:
连接词:that,whether,if(不充当从句的任何成分)
连接代词:what,whatever,who,whoever,whom,whose,which
连接副词:when,where,how,why
不可省略的连词:
1.介词后的连词
2.引导主语从句和同位语从句的连词不可省略。例如:
That she was chosen made us very happy.她被选上了,我们很高兴。
We heard the news that our team had won.我们听到消息说我们队赢了。
比较:whether与if均为"是否"的意思。但在下列情况下,whether不能被if取代:
1.whether引导主语从句并在句首
2.引导表语从句
3.whether从句作介词宾语
4.从句后有"or not"
大部分连接词引导的主语从句都可以置于句末,用it充当形式主语。例如:
It is not important who will go.谁去,这不重要。
It is still unknown which team will win the match.到底谁赢呢,形势尚不明朗。
名词性that-从句
1)由从属连词that引导的从句叫做名词性that-从句。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、同位语和形容词宾语。例如:
主语:That he is still alive is sheer luck.他还活着全靠运气。
宾语:John said that he was leaving for London on Wednesday.约翰说他星期三要到伦敦去。
表语:The fact is that he has not been seen recently.事实是近来谁也没有见过他。
同位语:The fact that he has not been seen recently disturbs everyone in his
office.
近来谁也没有见过他,这一情况令办公室所有的人不安。
形容词宾语:I am glad that you are satisfied with your job.你对工作满意我感到很高兴。
2)That-从句作主语通常用it作先行词,而将that-从句置于句末。例如:
It is quite clear that the whole project is doomed to
failure.很清楚,整个计划注定要失败。
It's a pity that you should have to leave.你非走不可真是件憾事。
用it作形式主语的that-从句有以下四种不同的搭配关系:
a.It+be+形容词+that-从句
It is necessary that…有必要……
It is important that…重要的是……
It is obvious that…很明显……
b.It+be+-ed分词+that-从句
It is believed that…人们相信……
It is known to all that…从所周知……
It has been decided that…已决定……
c.It+be+名词+that-从句
R>It is common knowledge that………是常识
It is a surprise that…令人惊奇的是……
It is a fact that…事实是……
d.It+不及物动词+that-分句
It appears that…似乎……
It happens that…碰巧……
It occurred to me that…我突然想起……
