英语单选题
1.Tom,go and get your coat,It`s_____you left it.(B)
A.there B.where C.there where D.where there
2.-Was his father very strict with him when he was at school?
-Yes.He had never praised him _______ he became one of the top student in his grade.(C) (为何不选B?)
A.after B.unless C.until D.when
请给出具体的语法解释!
1.B
where引导的句子翻译成“...的地方”
在这句话中where 引导的句子放在be动词后面,叫表语从句
翻译成“它就在你放的地方“
2.C
not ...untill (这里的never 就相当于not)
unless = if...not 代到句子里不符合题意.
翻译成:爸爸从来不表扬他,直到他成为了年级的尖子生.
另外,不能选B的原因还有时态不对.应该改为:
He would never praise him unless he became one of the top student in his grade.(主将从现)
