答案

Most students have never been to Europe,_____?
A.have they B.haven't they C.do they D.don't they
答案是A,为什么不选C
这里的have不是动词“有”的意思,不能用动词形式“do”回答.这是现在完成时的反义疑问,要用反义疑问词回答.
Would you please tell me_____?
A.when your father has come back
B.where would your father play tennis
C.why your father didn't watch the match
D.if your father had seen the film
答案是C,为什么不选A
A的说法要改成when your father came back 才可以.第一,看不出这里要用完成时,第二,时态也不对
＿＿＿of the twin sisters works as a waitress in the restaurant.
A.both B.all c.neither d.none
为什么选C
首先,是两个双胞胎姐妹之间,只能是用在两个人身上的A或者C.其次,如果选择“both”,后面的谓语动词就不可能是单数形式的“works”,而用否定意思的“neither”的谓语动词可以用单数.所以是C.
