问题补充:
All of my teachers but the math teacher he cheated in the exam.
A. doubt that
B. doubts that
C. doubt whether
D. doubts whether
答案:
A. doubt that
B. doubts that
(答案→)C. doubt whether
D. doubts whether
解析:考查主谓一致和宾语从句。本句的谓语动词要和all of mu teachers保持一致;故使用复数形式;因为句子使用了动词doubt“怀疑”;表示是不确定的事情的怀疑,故使用连词whether引导宾语从句,句意:除了数学老师以外的所有老师都怀疑他在考试中作弊了。故C正确。
