Question

—What did the doctor say?

—He asked how long _________.

1. A.
   has my daughter caught a cold
2. B.
   had my daughter caught a cold
3. C.
   my daughter had caught a cold
4. D.
   my daughter had had a cold

Answer 1

D
试题分析：宾语从句中一般为陈述语序。Catch为瞬间动作，不能和表示一段时间的时间状语连用，故选D。他问我的女儿感冒多久了。
考点：宾语从句及完成时态中动词与时间状语的搭配
点评：本题两个考点，宾语从句中的语序是考查的重点，应加强识记。关于瞬间动词的问题，指需要记住瞬间动词不能和表示一段时间的时间状语连用就可以了。
