　 介词+关系代词引导的定语从句，是学习定语从句的难点之一，是高考命题的重要考点常使用的关系代词一般为which, whom, whose,即可以引导限制性，也可以引导非限制性定语从句

[点拨]考生复习备考中需要注意如下几点：

1. Their personal life was regularly discussed by people who did not know them but talked as if they were close friends．素不相识的人们经常议论他们的私生活就像是谈论他们亲密的朋友一样。

1). 连词as if=as though，意为“仿佛，像，似乎”。通常用在be，look，seem，sound，taste，smell及feel等连系动词的后面。其后的从句可以用陈述语气，但多用于虚拟语气。如：

How wild his white hair looked as if it had been electrified!

他的白发十分凌乱，好像触了电似的。(虚拟语气)

She seems as if she is going to cry．

她似乎要哭了。(陈述事实)

2).as if (though)后面除了跟句子外，还可以跟名词、动词不定式、形容词(短语)、介词短语和分词。如‘

He acts as if a fool．他做事像个傻子。

He raised his hand as if to take off his hat．

他举起他的手，好像要取下帽子。

3). as if (though)还可以表达感叹语气，来对某项建议、假设和推测表示不赞成、惊讶、不满和厌恶等。如：

As if anyone would believe that story!好像有人竟会相信那样的事!

As if we were all stupid and he alone clever!

哼，就仿佛我们都是傻瓜，只有他一个人聪明似的。
