where ______the recorder?i can not see it anywhere
(1)选B
现在完成时的用法之一:过去的事对现在有影响.
题目中,“ i can not see it anywhere”就是“where have you put the recorder?”所产生的影响,故用现在完成时.
如果没有i can not see it anywhere,用一般过去时也没关系.
再看看下一句:“i put it right here”用的是过去时,“but now it is gone”并不是“i put it right here”所造成,故用一般过去时.
(2)选A
B,D是被动语态,而break out是没有被动词态,想一想,quarrel并不是“被”发生的,这样就容易理解了.
