Question

When he was at college, he and his friends          to organize a party.

A．are asking

B．were asked

C．was asked

D．asks

Answer 1

B

试题分析：根据前面的时态可知，本句应该是过去时，故排除AD；根据he and his friends可知，应该用were，故排除C。“Be +过去分词”是被动语态的结构。所以本题选B。
点评：完成本题时，首先应注意时态，然后确定语态问题。另外注意be asked to do sth.表示“被要求做某事”。
