——David injured his leg playing football yesterday.

题目

——David injured his leg playing football yesterday.
——Really?_________?
C.How did that happen
D.Why was he so careless
这两个选择哪一个,另一个为什么不选,请说明原因.

答案

c
这种答题就是不要夹杂个人感情,事件发生的结果有了,当然要问事件发生的原因.d选项很显然就是太主观了,难道David伤到腿是因为不小心造成的吗?
嗯,个人理解,不懂的话还是请教自己的老师比较好.
