爲什麼不能用THAT引導?什麼情況下什麼從句那些引導詞前要有先行詞?請幫我分析下句子結構謝謝
Many people have been ill from a strange disease these days,_______We』ve never heard of before.
A.one B.that C.it D.this
解答:
定語從句中不能用that引導的情況有這些
1、非限制性定語從句不能用that引導
我們不說 He failed the exam ,that was unusually difficult.
我們說 He failed the exam,which was unusually difficult.
2、如果先行詞是人,一般不用that引導
3、引導詞前面有介詞,不用that引導(一般用介詞+which引導)
比如 He gave me a ticket with which I can enter the meeting-room.《=====這樣才對
你說的這句句子是個非限制性定語從句,我們來分析一下
many people是主語,have been ill 是謂語,a strange disease 是賓語 ,these days 是時間狀語
然後有一個逗號,表示引導的非限定從
所以首先不能用thatB排除
it 引導的定語從句一般在主句句首做形式主語,構成it is ...結構,不在從句中做句首,c排除
this在定語從句中不用,D排除
根據排除法,選a
