The Bent Pyramid outside Cairo ______ ancient Egypt’s first attempt to build a smooth-sided pyramid.
A. has been believed to have been
B. was believed to be
C. is believed to have been
D. is believed to be
请问这题的答案为什么选C,可以给我讲解一下这题的语法点吗?
The Bent Pyramid outside Cairo ______ ancient Egypt’s first attempt to build a smooth-sided pyramid.
A. has been believed to have been
B. was believed to be
C. is believed to have been
D. is believed to be
此题命题不够严谨。我认为,有两个可选答案:A 和 C。
我分别讲解:
A. has been believed to have been
已被认定为过去是。
1. 不定式 to have been 用“完成体”是正确的,表示在谓语动词之前发生。
2. has been believed 是被动语态,意思是“被认为”。现在完成时表示这个看法是过去发生的,后面不定式的动作是“已经被人们认定”已发生了。has been believed 的意思是“已经被认定”。
所以,这个答案没有问题。
B. was believed to be
过去被认为是。不是现在的观点。
C. is believed to have been
现在被认为过去是。指现在人们的看法,而且此看法现在仍然存在着。
这个答案正确。
D. is believed to be
现在被认为是。指现在人们的看法。但是不定式用一般体 (be) 为错误。因为不定式表达的是过去的情况,须用完成体。
关于 have/has been believed to have done 的例句:
Officials from EgyptAir say an Airbus 320 plane has been believed to have crashed into sea.
已被认定为落入大海中。
Mount Ararat has been believed to have been the final resting place of the ark, which according to the Bible, came to rest on top of a mountain.
已被公认是方舟最后的安息地
