You're the only person ______I've ever met ______could do it.怎么填
答
You're the only person that I've ever met who could do it
你是我见过的唯一一个能做好它的人。
答
You're the only person that I‘ve ever met who could do it.
考察定语从句。这是一个复合句， 由两个定语从句组成。第一句You're the only person that I‘ve ever met 因为person 前面是the only, 所以关系代词只能用that，第二句I've ever met the only person who could do it,修饰人，且在句中作主语，关系代词用who.
答
You are the only person I've ever met who could do it.
答
that who
这两个都是定语从句，第一个空前面有the only ，后面先行词一定用that且不能省略。第二个空简单，填who ，。
