案件背景 在公司办公室内，主管大卫被发现离奇死亡，现场一片狼藉。经调查，有三名嫌疑人：Mike、Linda和Amanda。 1. 动机线索 - 初步排查：Mike近期因工作失误被大卫批评，面临绩效扣分和奖金扣除，存在报复动机；Linda一直觊觎大卫的主管职位，大卫若出事她有望晋升；Amanda则是因为大卫频繁对她进行言语骚扰，工作上也故意刁难。 2. 不在场证明线索：经询问，Mike的朋友证实其在昨天下午六点到八点时一直在看电影，时间吻合，能够证明他案发时不在办公室内，基本可以排除Mike作案嫌疑。 3. 现场痕迹线索：在会议室角落发现一把带血的水果刀，经检验是刺伤大卫的凶器。且大卫手指处有一团深色衣物纤维。 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $ 过去进行时 past continuous tense 目录 过去进行时的含义 01 过去进行时的句型 02 过去进行时的用法 过去进行时练习 04 03 Who is the big detective？ 谁是凶手？ 昨天下午六点半某公司老板David离奇地死在自己的办公室，名侦探毛利小五郎和柯南立即赶到案发现场进行案件侦查。此时目击警官正在排查嫌疑人，最后锁定了三个最有犯案动机的嫌疑犯。分别是秘书Amanda， 总经理Mike，财务会计Linda.
