我选的a 为什么

C.ought to be allowed not D.not ought to be allowed
我选a 但是一开始我就把bc排除了 为什么
3.my dog has never _____anyone,except when provoked.
A.bitten B.bit C.biting D.bite
这个我虽然选对了但是不知道为什么要用过去式
答
1. 不管是whether还是if都行，问句用Can提问就行了，但是后面的句子要用陈述句，因此只能是there is
2.ought后面直接跟否定副词not
3.这个地方其实不是过去式，是过去分词，跟前面的has一起形成现在完成时
答
1 if 和whether 都可以,但从句需要用陈述语句
2 ought to do应该做ought not to do 不应该做
3.has/have/had done 是现在完成时,加过去分词
