Question

Those boys _____ many times not to go on line, but it doesn’t make any difference.

A．have told

B．told

C．have been told

D．were being told

Answer 1

C

试题分析：考查时态语态：those boys和tell是被动关系，排除AB，根据第二句话，可知用现在完成时的被动，句意：这些男孩被告知很多次不要上网，但没有差别。选C。
点评：时态的考查要根据本句的关键词，本题的关键词是but it doesn’t make any difference.时态题还要考虑语态问题。
