i can't understand __at the poor little girl。a。 they laugh b。 their laughing c。 them to laugh d。 them why laugh本題考察understand的用法。understand的一個用法是：理解/了解某事物的重要性、意義，認識到。。。的道理或者原因：Do you understand the difficulty of my position?你理解我處境的困難嗎？I don't understand why he came/what the problem is。我不明白他為什么來。/我不明白這是什么問題。I just can't understand him/his taking the money。我無法理解他為什么要偷錢。可見：本題選b。屬于動名詞，而且their可以改成them。若a改成why they laugh 則也是正確答案。

按照賓語從句理解的話，只能是understand后省略了that，但按照漢語意思講并不通順，應是I can't understand why they laugh at the poor little girl.而選B是understand后接動名詞的用法。
