i ( ) dinner with my friends in the restaurant when the crime happened.have,had,was having
,have had,选什么?为什么?这是什么句型?

was having,主句用过去进行时,从句用when引导的一般过去时从句.这个主从复合句理解的难点在于：过去进行时表示的是一连串的,不间断的在过去某一段时间所发生的动作,而一般现在时所说的动作是在这当中的一个时间点上发生的.也就是说过去进行时表示的是时间的段,而一般过去时则表示这个时间段上的一个点.
例如：我昨天在街上步行时遇见了Tom.I was walking in the street when I met Tom yesterday.
