英语语法选择题(请说明原因)
It is now clear that no such creatures as vampires have seen and none _____in the world.
A.was found B.are found C.have been found D.have been found out
改正:题目少了一个been,应该是It is now clear that no such creatures as vampires have been seen and none _____in the world.
选A,很明显find的形式由其主语none决定,用第三人称单数.若用现在完成时需把have改为has.
