英语语法

34.He learned to speak the language so quickly and well that he_____have been taken for a native speaker.
A. must B. could C.should Dneed.

Answer 1

选B. could
【解析】could +have done 表示可能/本来……实际却没有
could have been taken for 表示可能被误认为/看作。。。
原句：He learned to speak the language so quickly and well that he could have been taken for a native speaker.
翻译为：他学会讲这门语言如此之快和如此之好以至于他可能被误认为是位本国人（母语为这语言的本国人）。 A.must必须，C.should应该 D.need需要 这三选项都不太符合原句意思，故选B.could
