5、在此期间发生。 如果时间状语从句放在主句之前，从句后要加逗号。,一般过去时+一般过去时 I looked at his screen . I started to laugh ,too. When I looked at his screen,I started to laugh ,too.,过去进行时+一般过去时 We were entering data on the system.

8、,因此when引导的时间状语从句中的动词可以是终止性动词,也可以是延续性动词,而while从句中的动词必须是延续性动词. when 说明从句的动作和主句的动作可以是同时,也可以是先后发生；while 则强调主句的动作在从句动作的发生的过程中或主从句两个动作同时发生. 由when引导的时间状语从句,主句用过去进行时,从句应用一般过去时；如果从句和主句的动作同时发生,两句都用过去进行时的时候,多用while引导,如： when和while 还可作并列连词.when表示“在那时”；while表示“而,却”,表对照关系.如： a.The children were running to move th
