Either the ways or the time _____ yet,but you may ask the headmaster for some information.
A.isn't decided B.hasn't decided
C.aren't decided D.haven't decided
为什么不选B?yet 不是用于完成时吗?

其实这道题不用看yet.此空一看就应用被动语态,排除BD,另外,either…or…引导的句子,谓语动词用单数,即可知选A
既然你问了yet,就说一下吧~
yet
adv.
1.还,尚,仍然2.已经3.甚至,更4.现在；即刻；马上 5.从现在起直至某一时间；还6.（表示将来可能发生,尽管现在似乎没有可能）早晚,总有一天7.迄今为止,到当时为止（最好的或最长的等） 8.（强调次数或数量的增加） 9.（强调程度的增加）更 10.（用于否定句和疑问句,谈论尚未发生但可能发生的事）
conj.
1.然而,但是
当yet表示已经、迄今为止时,用完成时.
从后面半句来看,此处yet的意思为“用于否定句和疑问句,谈论尚未发生但可能发生的事”,故,用一般式即可.
