Unit 5 Languages Around the World Discovering Useful Structures (ppt课件)-2022新人教版（2019）《高中英语》必修第一册.pptx

1、Unit 5 Languages Around the World Emperor Qinshihuang united the seven major states into one unified country where（地点状语）the Chinese writing system began to develop in one direction.（定语从句，修饰one unified country）It was a time when（时间状语）people were divided geographically.(定语从句，修饰a time)These were animal

2、 bones and shells on which symbols were carved by ancient Chinese people.（定语从句，这是介词+关系代词引导的定语从句，修饰animal bones and shells）There are many reasons why（原因状语）people learn a foreign language.（定语从句，修饰reason）关系副词的作用如下：1指代表示时间、地点、原因的先行词。2在从句中充当句子成分状语，即在从句中起副词的作用。3起连接作用，把主句和定语从句连接起来构成主从复合句。定语从句()关系副词的用法当引导定语

3、从句的关系词在从句中用作时间、地点、原因状语时，应使用关系副词when,where,why或“介词which”。1when引导定语从句when表示时间,代替先行词并在定语从句中做时间状语，其先行词往往是表示时间的名词，如time,day,year,month,week等。2where引导定语从句where表示地点,代替先行词并在定语从句中做地点状语，其先行词往往是具体地点place,room,mountain,airport或抽象地点的名词如case,state,condition,point,situation等。3why引导定语从句的用法why表示原因,代替先行词并在定语从句中做原因状语，

4、其先行词是表示理由的名词reason。一、关系副词引导定语从句二、关系代词与关系副词的选用定语从句的引导词用关系代词还是关系副词可以用以下两种方式判断：用法用法依据依据根据从句的谓语动根据从句的谓语动词词是及物动词，后面若无宾语，用关系代词；是不及物动词则用关系副词根据先行词在从句根据先行词在从句中所作的成分中所作的成分把先行词代入定语从句中，若作主语或宾语用关系代词；作状语则用关系副词三、介词+关系代词引导的定语从句关系副词when,where,why引导定语从句时，关系副词也可用“介词+关系代词“代替。(1)when可以换成“介词which”。(2)where可以换成“介词which”。(

5、3)why可以用for which来代替。1、介词选择的三原则：一先二动三意义。一先：根据先行词的搭配习惯来确定。二动：根据从句中谓语动词的搭配习惯来确定。三意义：根据从句所表达的意义来确定。2、介词可以后移，此时关系代词可以忽略。3、名词/代词/数词+of+关系代词 引导的定语从句通常是非限制性定语从句，该结构在定语从句中一般作主语。When I started studying German,it was a struggle.The words felt strange on my tongue,and the grammar would not stay in my head.I to
