As一般放在句首，which在句中.As we know, smoking is harmful to one's health.The sun heats the earth, which is very important to us.as和which引导非限制性定语从句，有相同之处也有不同之处。

(3) This is the same book as I lost last week.简单归纳: as ,which均可以引出非限制性定语从句, 如都指前一句话的意思,二者可以互换。

非限制性定语从句的引导词有所特点，本文将详细介绍非限制性定语从句的引导词及其特点。
一、引导非限制性定语从句的引导词引导非限制性定语从句的引导词包括"which"、"who"、"whom"、"whose"、"that"等。
这些引导词根据被修饰名词的不同类别和所表示的信息进行选择。
1. "which"用来修饰事物，表示非限制性定语从句的引导词。
例如：The new smartphone, which was released last week, is selling well.（新上市的智能手机卖得很好。
）2. "who"用来修饰人，在非限制性定语从句中作为引导词。
例如：Peter, who is my best friend, is coming to the party tonight.（彼得，我的最好朋友，今晚要来参加派对。
）3. "whom"也用来修饰人，但通常用在非限制性定语从句中作为宾语。
例如：The woman, whom I met yesterday, is a famous writer.（那个我昨天见到的女人是一位著名的作家。
）4. "whose"用来修饰所属关系，表示非限制性定语从句的引导词。
例如：John, whose father is a doctor, wants to become a lawyer.（约翰的父亲是医生，他想成为一名律师。
）5. "that"用来修饰事物，在非限制性定语从句中作为引导词。
非限制性定语从句
(1)限制性定语从句和主句的关系十分密切， 若省去，主句的意思就不明确。主从句之间 不用逗号隔开。而非限制性定语从句则不然。 试比较：
This is the best book that I have read. This is a good book, which is easy to understand.
(2) 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

在非限制性定语从句中，我们使用特定的引导词和结构来构建句子。
本文将对非限制性定语从句的引导词和结构进行解读。
一、引导词1. which：which 是最常用的非限制性定语从句引导词，用来指代或解释先行词的内容。
其后的从句与主句之间使用逗号分隔。
例如：I have a cat, which is very cute. （我有一只猫，它非常可爱。
）2. who：who 用来指代人，并引导非限制性定语从句。
与 which 类似，who 也应该与主句之间使用逗号隔开。
例如：Tom is my best friend, who always supports me.（汤姆是我最好的朋友，他总是支持我。
）3. whom：whom 也用来指代人，但在非限制性定语从句中常用作宾语。
同样需要在主句之前使用逗号与从句隔开。
例如：Lucy is a talented singer, whom I admire a lot.（露西是一位才华横溢的歌手，我非常钦佩她。
）4. that：虽然 that 可以在限制性定语从句中使用，但在非限制性定语从句中使用较少，一般情况下我们会选择 which 或 who。
5. whose：whose 是一个特殊的引导词，用来表示所属关系。
常用于人和物的非限制性定语从句中，引导词后面跟名词。
例如：This is Jack, whose car was stolen yesterday.（这是杰克，他的车昨天被偷了。
）二、结构除了引导词，非限制性定语从句的结构也需要注意。
一般来说，非限制性定语从句需要放置在主句后面，两者之间使用逗号隔开。
例如：My sister, who is a doctor, lives in New York.（我的姐姐是一名医生，她住在纽约。

非限制性定语从句谓语动词用单数还是复数？
非限制性定语从句谓语动词用单数还是复数？今天**的是一个微博精品文章，这个文章虽然我微博发过，但是我觉得很重要，再发一次新的精品班7月24日开始（明天）！8月预测班（口语+写作）7月20日开始(还可以插班)！语法班7月17日开始！非限制性定语从句既可能修饰一个名词，也可能修饰一个句子在写一个非限制性定语从句的时候，情况A：写完主句后，你要看看自己的主句是不是一个名词结尾，而这个主句是不是作为从句的主语如果不是名词结尾，关系代词用which，从句的谓语动词可以用单数譬如说我想说：很多小公司的员工都要工作很勤奋，这已经成为一个普遍现象前面是主句，工作很勤奋，work hard不是名词，所以从句我用了which hasMany employees of small companies have to work very hard, which has become the norm in the workplace.情况B：写完主句后，如果主句是一个名词结尾，而且从句不管修饰句子还是修饰这个名词都说的过去，这个时候要看名词的性质，B1 这个名词如果是单数或者是不可数名词，相对来说比较简单如果我想说：很多人现在都很注意员工培训，这对事业有帮助前面主句的结尾是一个名词，training，这是一个不可数名词，这个时候要看名词是否是单数或者是不可数名词，如果是，谓语动词可以用单数Many people today pay attention to on-the-job training, which is important to their career success.B2 这个名词是复数，特别还是表示人的名词，要特别小心处理如果我想说：很多人现在都很注意和同事的关系，这对事业有帮助这个句子就比较复杂，有可能结尾是colleagues, 也可能是relationships我会尽量使用情态动词，can, may 等，这么写，因为情态动词没有单复数，不管修饰前面整个句子，还是前面的复数名词，语法都没问题Many people today pay attention to their working relationships, which can be vital to their career achievement. （）如果我的从句谓语动词用are，就不是很好，因为如果修饰整句主句，那么谓语动词用单数才对Many people today pay attention to their working relationships, which are vital to their career achievement. （×）如果我的主句用colleagues结尾，问题就很更大，colleagues是人，和后面的关系代词which有冲突Many people today pay attention to their relationship with colleagues, which are important to their career success. (×)情况C：写完主句后，如果主句是一个名词结尾，而且从句肯定只可能修饰这个名词，而不可能是前面的句子，这个时候从句的先行词和谓语单复数随着名词变化如果我想说：很多度假的人都对历史建筑感兴趣，这些建筑都有独特的建筑方式这个句子的结尾是historic sites，而且铁定是从句的主语，从句不可能修饰感兴趣这个事情Many holidaymakers are interested in historic sites, which normally have unique architectural styles. （）对网络课程咨询和报名感兴趣的同学，请点击左下右方的阅读原文或发信息课表至对话框，获得课程信息。
