A huge flying reptile that died out with the dinosaurs some 65 million years ago, the Q 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 believd E.which is believed to be
答案:C,我选A,
!)LZM的解释说:因为有die out 说明是过去的事,必须用完成时,但是题目有ever,表示"曾经",这本身就是说明过去的事了,不用另加完成时了.用现在的不定式即可了.
以下是引用1stzhang在2003-5-14 10:06:00的发言: 当两个动词连用的时候,一定要注意动词的发出的先后顺序。believe是现在发生的,而be这个动作是在believe之前发生的。为了让句子不出现歧异和更加合理,在时态上面就必须体现出来。如果把a改为believed to have been ,我认为A更好!
还要请教,如果believed to have been。 那么该分词结构在全句中做什么成分呢? 根据LZM,过去分词可以做定语,或在句首做状语。 而且从语法上,believed to have been优先修饰wingspan , 不知道这样算不算是歧异。 另外,过去分词本身含有完成概念,后面能否再加完成时呢?
