Write a conversation according to 2c. Unit 10 Ive had this bike for three years. 第一课时第一课时 Section A(1-2d) 【Free【Free talk】talk】How long have you had your bike? 【学习目标学习目标】 1. 学习下列单词：yard, sweet, cent, toy, bear, maker, scarf, soft, board, check 2. 学习下列短语：yard sale, board game, check out, more than, bring back, give away, notany more, welcome to, 3. 能熟练运用下列语句询问活动情况： 1.

I have learned about 2000 English words so far. 注意：常用 How long .? 提问现在完成时的时间。 1）延续性动词：动作可持续一段时间，可和 for, since 等表示一段时间的时间状语连用。 2）非延续性动词：动作不能持久，一瞬间就结束，不能延续，或表示一次性动作，也叫短暂 性动词、瞬间动词、终止性动词。不能和表示一段时间的时间状语连用。常见这类动词有 come, go, leave, begin, start, arrive, reach, see, die, join, get up, borrow, lend, buy, finish, end, become, hear from 等。 *判断正误如有错误并改正: 1.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 soldier go 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 open d) 转换成“be + 介词短”语形式 go to schoolbe in school; join the armybe in the army 5)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.
