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,这一事实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 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……
