7．The girl was shopping when the alien out．（ ）| A． | goes | B． | went | C． | will | D． | is going |
分析 句意：当外星人走出来的时候，那个女孩正在买东西．
解答 答案B．在过去进行时里，如果含有时间状语从句的复合句，延续性动词用过去进行时，非延续性动词用一般过去时．因为go是非延续性动词，是瞬间发生的动作，所以需要用一般过去时went．故选B．
点评 此题考查了过去进行时的主从复合句，需要分清楚动词是延续性动词还是非延续性动词．如果从句是非延续性动词，需要用一般过去时，如果主从句都是延续性动词，则都用过去进行时．
