2015年职称英语考试常用语法详解:名词性从句
什么叫名词性从句?
在英语句子中,主语、宾语和表语是名词,在这三个位置上出现的句子就称为名词性从,即:主语从句、宾语从句和表语从句的总称。由于他们的连接原则和连接词的使用基本一致,故放在一起讲解。
如何连接?
名词性从句的连接可以简单地归纳为三句话:
1) 从句不缺成分用that
2) 从句缺少主语、宾语和表语,物用what,人用who / whom / whoever / whomever
3) 其他情况,中文缺什么意思就补所需的带-wh的词,
第一句话:从句不缺成分用that,例如:
My hope is that she will soon be well again.
Everybody hopes that she will soon be well again.
That she will soon be well again is our hope.
1) 名词性从句中的that 只是起连接作用,不充当任何成分,一定要与定语从句中的关系代词that相区别;
2) 除了主语从句居首的情况,是可以省略的,特别是宾语从句中。例3也可以写成:It is our hope that she will soon be well again.
此项内容不是考试重点。
第二句话:从句缺少主语、宾语和表语, 物用what,人用who / whom / whoever / whomever
这是名词性从句考试的重点, 特别是what, 这里的关键是否能辨认出句子的成分,
例如:
______ he needs is more time.
显然,主语从句中:he是主语,而谓语动词needs缺宾语,因此填what
Tell us _____ you saw and heard during your visit to that university.
同样,宾语从句中谓语动词saw和heard缺宾语,应填 what
This is not ______ I want. 同样,表语从句中动词缺宾语,应填what
______ some people are against is ______ other people are for.
这是一个主语从句 + 表语从句的结构,介词against和 for后面都没有宾语,无疑都应填what:一些人反对的就是其他人赞成的。
应注意的问题:
1) 关于what的疑问性和名词性:
I dont know what you dont know.
这个句子可以有两个译文:我不知道你不知道什么。/ 你不知道的我也不知道。显然,第一个译文中what是疑问性的;第二个译文中what是名词性的,中文往往表达为的.
注意:这种区分并不影响做语法选择题,只影响翻译理解.
例如:
What has made Japan ______ it is today?
不要急着试图翻译这个句子,先考虑一下从句中缺了什么成分?缺表语,即: it is 的表语,那就填what, 即:What has made Japan what it is today? 是什么使日本成为今天这个样子?句中第一个what是疑问性的,第二个what是名词性的。
2) 关于whoever和whomever的用法:
上面讲到,what具有疑问性和名词性。同样,讲到人谁时, 也有疑问性和名词性之分。现代语法规定,疑问性 谁?用who / whom,名词性谁 = 那个人用whoever/ whomever. , 例如:
谁迟到就开除谁。该句中的谁不是问哪个人迟到了?,而是说迟到的那个人,显然是名词性的,应译为:Whoever comes late will be fired.
这也是目前语法考试的一个重点。
3) 用who 还是whom?
We are talking about ______ will attend the meeting.
在个句子中,尽管空格______的位置在介词about 后面,属介词宾语的一部分,但它在从句中做主语,因此还是应该填who 而不是填whom;此原则同样适用于whoever与 whomever之间的选择。
第三句话:其他情况,中文缺什么意思就补所需的带-wh的词,例如:
I wonder whether he will come in such bad weather.
名词性从句有两个两个重点:what 和whoever
