求解。
请各位大侠，详细解答一下这题，万分感谢。
refer to ：提及、涉及、参考。
speak of ：说起、说到。

Answer 1

我知道AMY在她还是个开朗的女孩时就被交付于老师。a bright gir是对Amy的形容修饰，referred表示被交付于，C

Answer 2

这句话意思应该是“我知道老师指的是Amy当他说到一个聪明的女孩时”，那前面一空应该是 I know (that) the teacher_referred_____to Amy （不用.was referring 因为refer是短暂性的）。后面的应该是 when she __was speaking____ of a bright girl(不用spoke，因为他正 论及 这个女孩）

这只是我的理解，可能是这样的吧~

I konw the teacher referred Amy when she was speaking of a bright girl
我知道老师指的是艾米当她是说一个聪明的女孩时
选C

Answer 4

其实这是一道原自2009年云南省高考复习第二次检测卷中的单选题。恰恰相反，refer to可以理解为延续性动作。而speak of“说起、谈及”为短暂性动作。
I know the teacher was referring to Amy when she spoke of a bright girl.
when 引导的时间状语从句中的谓语动词可以是短暂性动词，也可以是延续性动词。但有区别：
When students were talking and laughing, the teacher came in.
