He has come back. ( )_2. He has come back for 3 days. ( )_3. I have borrowed the book. ( )_4. I have borrowed the book since last week. ( )_5. I have got up for an hour. ( )_6. He has died for 10 years. ( )_3)非延续性动词的否定式已成为一种可延续性状态，可以和for,(后跟时间段) since（后跟时间点或一般过去式的从句）等表示一段时间的时间状语连用。1. I havent seen him for a long time. / since he _(离开)2. I havent heard from him for half a year.3. I havent borrowed books for two months.4) 非延续性V. 可以转换为延续性V.，有以下几种情况：用相应的延续性动词buyhave; borrowkeep/have; put onwear; catch(get) a coldhave a cold; come/go/becomebe 转换成“be + n.”形式join the Partybe a Party member join the armybe a soldiergo to schoolbe a student转换成“be + adj./adv.”形式diebe dead; finishbe over; beginbe on; leavebe away; fall asleepbe asleep; wake upbe awake; get upbe up; closebe closed; openbe opend) 转换成“be + 介词短”语形式go to schoolbe in school; join the armybe in the army5)Practice：他回来已三天了。_他离家已有两个月了。_他父亲已死了三年了。_他已睡了一小时了。_这场电影已经开始一小时了。_三、当堂检测 翻译下列句子1) -你哥哥参军了吗？_-他参军了。_-他什么时候参军的？_-他是1990年参军的。他参军已5年了。_2)-你父亲去哪了？_?-他去美国了。他是3年前去的。他在那儿已呆了3年了。_3） I _ an English-Chinese dictionary.
