fisherman, army, wound, secretary, engineerdied (in 1992) →has been dead (for eighteen years)left (in 2002) →has been away (for eight years)
(让学生独立完成2b，然后引导学生总结非延续或延续性动词在与时间段连用时动词的转换情况，板书总结的内容并作补充讲解。)
含有for+时间段/since+时间点/how long …等句子里的谓语动词需要用延续性动词。die→be dead, leave→be away (from)come→be in, join→be a member of/be inbuy→have, borrow→keep
Step 5 Project 第五步 综合探究活动(时间:5分钟)
