Grammar and usage
Nn-restrictive attributive clause
关系代词which、wh、whm、whse关系副词when、where
非限制性定语从句是对先行词或整个主句的补充说明，与主句之间通常用逗号隔开，如：Davis wanted t visit Dr Yuan’s new farm , where seawater rice was grwn.Laura culdn’t cme t ur party , which was a pity.
1. which引导非限制性定语从句时, 先行项可以是某个单词或短语, 也可以是整个主句或主句的一部分。e.g. She heard a terrible nise , which brught her heart int her David studies hard and is ready t help thers , which is what his parents expect.2. 在非限制性定语从句中whm、which前面可以sme f、many f、all f、mst f等修饰词，表示整体中的部分或所有。The grwing speed f a plant is influenced by a number f factrs, sme f which are beynd ur cntrl.
3. as和which都可引导非限制性定语从句，指代整个主句的内容，但有区别：as引导的从句可以位于主句前、主句中和主句后，主句没有前后逻辑关系，常表示“正如”。which引导的定语从句只能放在主句后，主从句常有一定的因果关系或前后顺序，常表示“这一点”。e.g. Liquid water changes t vapr, which is called As everyne knws, all that glitters is nt gld.

Subject clause
主语从句的连接词有：从属连词：that，whether，if连接代词：what，which，wh，whm，whse，whatever，whichever，whever， whmever连接副词：when，where，why，hw
在复合句中，如作主语的是一个从句，该从句被称为主语从句。如：Hw much we will learn frm the telescpes is merely limited by ur imaginatin.
这里的hw much引导主语从句。
1. that不充当句子成分，无语义，只起连接作用，不能省略。e.g. That Hubble is based in space allws it t see further than grund-based telescpes.2. whether 不做成分，表意思“是否”。Whether he will cme r nt is nt knwn yet.It's uncertain whether/ if he’ll cme this evening.
注意：用whether 不用 if 的情况：1. 主语从句位于句首时; 2. 从句后有r或紧跟r nt时。
3. 连接代词wh(ever)(无论)谁主语、宾语、表语whm(ever)(无论)谁宾语whse(ever)(无论)谁的定语what(ever)(无论)什么主语、宾语、表语、定语which(ever)(无论)哪一个主语、宾语、定语
