23. A huge flying reptile that died out with the dinosaurs some 65 million years ago, the Quetzalcoatlus had a wingspan of 36 feet, believed to be the largest flying creature the world has ever seen. (A) believed to be (B) and that is believed to be (C) and it is believed to have been (D) which was, it is believed, (E) which is believed to be
答案为B.
E为什么不对? 找了以前的帖子,有说E中的which不对,就近指代feet. 但是做OG就发现有些题目是which可以跳跃指代. 谓语动词和主语保持一致. 避免一些歧义. 这一题不可以吗?
which跳跃指代Quetzalcoatlus, 谓语动词用IS.不可以吗?
另一种理解:E中错误为时态,believed后面应该用完成时,那么,E改为which is believed to have been. 是否就对了呢???
晕了. 恳请高人解释一下~~
