在作文中从句怎么练习【一】

基本概念定语：用于修饰名词或代词的成分就叫定语。定语从句：如果修饰某个名词或代词的定语是一个完整的句子，这个句子就叫定语从句。定语从句所修饰的名词或代词叫先行词。定语从句放在先行词后面。定语从句的引导：定语从句的引导词代替的是先行词。

1、当定语从句所修饰的名词是事、物时，用that/which引导，且that/which在定语从句中作主语或宾语。e.g:a.Thisisthepenthat/whichIboughtyesterday.

2.当定语从句所修饰的名词是人时用that/who引导，引导词再从句中做主语或宾语。

3.定语从句修饰的'名词时地点时用which/that或where引导:若地点名词在定语从句中是作主语或宾语就用that/which引导，是作地点状语则用where引导，可与“介词+which”互换。作visited的宾语作介词in的宾语作work的地点状语

4.当定语从句修饰的名词是时间名词时：若在定语从句中作主语或宾语用that/which,作时间状语则用when,同样可与“介词+which”互换。

5.当定语从句所修饰的名词在定语从句中表示原因时用why。’tcomeisstillamystery.

6.当定语从句修饰的名词和引导词后面的那个词之间是所有关系时，用whose引导。女儿已经出国的那个人是位医生

一般说来，用on和at表示“as soon as, once”。on后面常接“来、去”之类的词，at后面常接“听到、看到”之类的词。in后面接其他带动作的词，相对于从属连词“while”。

例1：On removing them he was stunned to see that the plates were fogged where the crystals had covered them.当他把晶体揭开时，发现盘子上方雾蒙蒙，他吃了一惊。

例2：In running down the stairs, I heard the clock struck twelve.

例3：He jumped with joy at hearing the news.他一听到这个消息就高兴得跳了起来。

如果定语从句的时态与主句的时态具有同时性(包括谓语有情态动词或之后性，则可以用“关系代词或关系副词+不定式”来简化，或直接用“不定式”来修饰先行词。要注意的是，此时的不定式一定要是及物动词，如果是不及物，则需要在动词后面加上相应的介词，使之成为及物动词短语。这个结尾的介词可以提前到关系代词前面，也可以继续留在句尾。前者是正式说法，后者是非正式说法。

例1：We moved to the country so that the children would have a garden in which they could play in.
