Question

All those students who are not brave enough to        in class should        .

A. say; pay attention    B. tell; be paid more attention to

C. speak; be paid attention to    D. talk; pay attention to

Answer

C

【解析】句意：所有那些不够勇敢在课堂上发言的学生都应该被注意。say说，强调内容；tell告诉；speak说话，发言；talk 交谈，谈话；pay attention to是固定短语，注意...。第一个空应表示在课堂上讲话，只强调动作，故用speak；第二个空是被动语态的形式，这句话的主语All those students和pay attention to构成被动关系。故应选C。
