《强调句》
it is /was+被强调部分(主、宾、状)+that/who
判断方法:去掉it is /was 和 that/who ,如果句子仍然是完整的,则该句型就是强调句。句子如果不完整,则是定语从句。
强调句的一般疑问句形式是was it… that/who
强调句的特殊疑问句it was not until …that…
谓语动词人称和数的一致性 eg:it is i who am right. It is he who is wrong .
It is the studengts who are lovely.
4. Who和that 的选用:①强调人时用that或who都可以②既强调人又包括物时只能用、强调时间状语、强调地点状语、强调原因状语用that
,应根据句子的需要选择它的主格或宾格形式
Eg: It is(B) who want to see you ? B. he C. his
--what is mary ?
--was it (C) that you were reffer to?
强调句型中定语从句和时间状语从句易混淆的句型判断
①在“it+be动词+点时间+其它”这一结构中若在表达点时间的名词前有介词时,则该句型属于强调句型,名词后应接that 。若在时间名词前无出现介词后接引导时间状语的连词when或before。
It was at six o'clock that the accident occured .(强调句型)
It was six sharp when the accident happened (时间状语从句)
it was +一段时间的结构,若段时间后有ago或 later 时常用引导强调句型的连接词that,若段时间后无ago或later,常用表示相隔之长之短的连接词before。
Eg:it was twenty centuries ago( that)the Great e into being .
it was five years later (that )he came back from abroad .
it was some time (before) we realize the trueth .
注意:强调句一般考察的是选择题、完型、改错。
二《定语从句》
:①修饰前面的主语、宾语、表语、定语
②前面是人时用who、whom、that
③前面是物时用what、that、which
关系副词:①修饰前面的状语(地点状语、原因状语、方式状语、时间状语)
②重要有where、why、how、when
3在做此类题时常常有选择题里面:what=名词+which/that whose +名词=of who/which
,在宾语从句中充当成分,当and连接两个以上的定从,第二个that不可省略。
matter +what/who/which/when (状语从句)
whoever/whatever/ whichever/whenev
