Which of these sentences is correct ?
A．She wondered what’s wrong with her dog.
B．I am not sure what does he do for a living.
C．Nobody knows how he repaired his broken bike this morning.
D．He asked if that it would rain the following day.
答案
答案：C
题目分析：句意:下面的句子哪个是正确的。这题考查的是宾语从句。我们需要注意三个问题，即宾语从句中用陈述语序、宾语从句的引导词及宾语从句的语态要与主句一致。故A选项错在时态上，应用一般过去时；B选项用的是疑问语序；D选项中引导词if和that重复了。故选C。
