问题补充：
I have French. What about you?
A. many difficulties to learn
B. a few troubles in learning
C. quite a little difficulty to learn
D. a great deal of trouble learning
答案：
A. many difficulties to learn
B. a few troubles in learning
C. quite a little difficulty to learn
(答案→)D. a great deal of trouble learning
解析：考察固定句式。固定句式：have some trouble （in） doing sth做某事有困难。其中的trouble是不可数名词，不能使用a few修饰。句意：在学习法语方面我有些困难，你呢？故D正确。
