试做真题 透析真题 高手必备 萃取高招 对点精练 (一)状语从句 判断是定语从句还是状语从句的关键是寻找是否有先行词,有先行词的句子则为定语从句。由when和where引导的句子,其前面无先行词则为状语从句。如: It was five o’clock when Tom came to see me yesterday afternoon.(句中无先行词,故when引导的句子为时间状语从句,it指时间) When you read the book,you’d better make a mark where you have any questions.(句中无先行词,where引导地点状语从句) 试做真题 透析真题 高手必备 萃取高招 对点精练 (二)同位语从句 定语从句与先行词之间是修饰与被修饰、限制与被限制的关系,从句说明先行词的性质或特征,关系词(或先行词)在定语从句中必须充当相应的成分。而同位语从句中从句与其前面的名词之间是等同关系,进一步说明其具体内容,连接代词只能用that,而不能用which,且在从句中不充当任何成分。如: The news that I heard over the radio was exciting.(定语从句,先行词在从句中充当动词heard的宾语,说明news是从收音机里听到的)? The news that our football team won the match is exciting.(同位语从句,说明news的具体内容)? 试做真题 透析真题 高手必备 萃取高招 对点精练 (三)强调结构 判断句子结构是否是强调句型可用还原法,即将被强调的部分放在从句中相应的位置,不需要再添加任何词语句子就是正确的,即为强调句型结构。如: It was at five o’clock that Tom came to see me yesterday afternoon. It was in the bookstore that I met your brother the other day. (四)并列结构 若句与句之间有并列连词and,but或分号、句号,则该结构为并列结构,若无则为定语从句。 Last night I took a taxi,and it took me straight home. 此时属于并列结构,若将并列连词and去掉,it改为which,则为非限制性定语从句。 试做真题 透析真题 高手必备 萃取高招 对点精练 Tom’s mother kept telling him that he should work harder,but it didn’t help. 若将but去掉,则应填which,成为非限制性定语从句。 The weather turned out to be very good,which was more than we expected. 该处为which引导非限制性定语从句。 He paid the boy $10 for washing ten windows,most of which hadn’t been cleaned for at least a year. 该处为which引导定语从句。若将逗号改为分号或句号,或在most之前加并列连词and,均需将which改为them。 试做真题 透析真题 高手必备 萃取高招 对点精练 高招1根据指代和成分正确判定和选择关系词 典例1 A company 　　　　　　profits from home markets are declining may seek opportunities abroad.(山东真题)? 【剖析】 whose　句意:国内市场利润下降的公司可以从国外市场上寻找机会。本题考查定语从句。所填词whose引导定语从句,并在从句中作定语。 典例2 The book has helped me greatly in my daily communication,especially at work 　　　　　　?a good impression is a must.(江苏真题)? 【剖析】 where　句意:这本书在日常交流方面对我帮助很大,尤其在那些要求必须具备良好外部形象的工作中。work在此为表示地点的名词,其后是一个定语从句;要填的词引导从句并在从句中作地点状语,故用关系副词where。 试做真题 透析真题 高手必备 萃取高招 对点精练 典例3 English is a language shared by several diverse cultures,each of 　　　　　uses it differently.(天津真题)? 【剖析】 whi
