Question

A good teacher has to be armed with the ability to keep students _______ throughout their learning process．（　　）

A. motivating

B. motivated

C. motivate

D. to be motivated

Answer 1

答案：B
题干中非谓语动作motivate作keep的宾语补足语，motivate与students之间构成动宾关系，要用被动，即keep students motivated让学生受到激励；句意表达的是客观事实，不是未发生的动作，不能用动词不定式．故选B．
