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
7.一些特殊情况:
1.从句为陈述句,常选择引导词that,that引导宾语从句无意义,不充当句子成分常省略。例句:He told us (that they would help us through the whole work.
2.从句为一般疑问句,常选择引导词if或whether,表示“是否”。在whether … or not结构中不能用if替换。例句:I don’t know if there will be a bus any more.
3.从句为特殊疑问句,常选择what,when,where,which,who,how等的疑问代词、副词作引导词。例句:He didn’t tell me when we should meet again.
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.
我在跑下楼的时候,听见钟敲了十二下。
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。
这是一幅有关文明环保的漫画。
一个阳光明媚的下午,小红和小明两个要好的好朋友手拉着手走在放学的路上。空气是那样新鲜,花香是那样芬芬,他俩沉浸在那美妙的世界里。他俩走呀走直到垃圾桶的旁边,垃圾桶恶臭的味道打破了那美妙的世界,原来是有人把垃圾倒在外面了。小红破口大骂:“是谁这么缺德,这么懒,把垃圾倒在外面!”说完,就准备弯下腰去捡。小明一把拉住他,说:“不用,不用,清洁工会来弄干净的,我们回家吧!”“不行,我们是环保小卫士。”小红对小明说。一次、两次、三次她挥汗如雨,小明看见这样的场景很愧疚,心想:现在干净了,以后还会有人这样做,该怎么办呢?小明抓抓脑袋,有了,只见他纸上写“文明——只差一步”,贴在垃圾桶上,贴完,他俩就高高兴兴地回家了。
不要因为懒,就把垃圾倒在外面。
