2. B.
   have you played, had
3. C.
   had you played, have had
4. D.
   do you play, have had

Answer 1

B
试题分析：考查时态。本题第一句中的时间状语是up to now直到现在，与现在完成时使用；第二句中的时间状语是last night这是一个很典型的过去时的时间状语。句意：—到现在为止你举行了多少次演奏会？—大约25次，昨天晚上我们举行了最大的一次。故B正确。
考点：考查时态
点评：时态的考查关键是要抓住句子的时间状语，如第一句中的up to now。在平时要注意一些典型的时间状语和时态的连用，如all the time与现在完成进行时连用等。
