【3年高考2年模拟】2016届高三英语一轮复习课件语法专练三定语从句

　　其中关系代词as在从句中充当主语、宾语或表语。如: We have found such materials as are used in their factory. 我们已经找到了像他们工厂里用的那种材料。(as作主语) These houses are sold at such a low price as people expected. 这些房子以人们预料的那样的低价出售。(as作宾语) He is not the same man as he was. 他和过去不同了。(as作表语) 注意:such...as引导的定语从句与such...that引导的状语从句的区别: ①He is such a clever boy as everyone likes. 他是一个人人都喜爱的聪明的男孩子。 ②He is such a clever boy that everyone likes him. 他是一个如此聪明的男孩子,以至于人人都喜欢他。第一个句子中such...as引导的是定语从句,as在从句中作宾语;而第二个句子中such...that引导的是状语从句,从句中不缺任何成分。 2....such as... such为代词,意为“这样的人或物”,as在从句中作成分,修饰先行词such。如: This book is not such as I expect. 这不是我想要的书。(as作宾语) (六)关系代词as,which的区别 1.as 引导的非限制性定语从句,既可在主句前,又可在主句后,有时还可插入主句中,而which引导的非限制性定语从句只能置于主句之后。相同的是两者都可替代整个主句的内容。如: The weather turned out to be very good,which was more than we could expect. 结果天气很好,超出了我们的预料。 2.当非限制性定语从句放在主句前面时,只能用as。如: As is known to everybody,the moon travels round the earth once every month. =The moon travels round the earth once every month,as/which is known to everybody. =It is known to everybody that the moon travels round the earth once every month. =What is known to everybody is that the moon travels round the earth once every month. 众所周知,月球每月绕地球转一次。后两句属名词性从句范畴。另外,as多用于下列习惯用语中:as anybody can see正如人人都能看到的那样;as is well known=as is known to all众所周知;as we had expected正如我们所预料的那样;as often happens正如经常发生的那样;as has been said before如上所述;as is mentioned above正如上面提到的。
