I've had it for three years. How long has his son owned the train and railway set? He's owned it since his fourth birthday. Have you ever played football? Yes, I did when I was little, but I haven't played for a while now. 1）现在完成时的特殊疑问句的结构是什么？用什么疑问词来询问拥有某物品的时间？ 3）since 后面接什么 2）for 后面接什么 for 和 since 在现在完成时中的应用 for与since都能与现在完成时连用，但区别较大： (1) for后须接“时间段” e.g. He has studied English for five years. (2) since后须接“时间点” e.g. He has studied English since 1999. (3) 二者可以转换 for +一段时间 = since + 一段时间 + ago e.g. He has been here for five weeks. = He has been here since five weeks ago. for 和 since 在现在完成时中的应用 (4) since能引导时间状语从句(主句用现在完成时，从句用一般过去时)，而for则不能。 e.g. He has taught here since he came to China. We have been friends since we met in school. (5) 现在完成时常用句型： ①It is/has been +时间段+ since +时间状语或从句 e.g. It is four days since last Friday. It has been two years since Jim came to Beijing. (6) 均须与延续性动词连用，也可以与非延续性动词的否定式连用。 e.g. I have bought this computer since four years ago. (×) I have had this computer since four years ago. (√) I haven’t bought anything for two months.(√ ) I haven't heard from him for 3 weeks. (√) 判断下列哪个是时间段还是时间点，用for或since填空： for + 时间段 since + 过去时间点 _____ 100 years _____ 1 minute _____ 2010 _____ three o’clock _____ half an hour ago _____ last year _____ I was 10 years old _____ more than 2 weeks for for since since since since = one year ago since for We haven't seen each other _______a long time.

Grammar How long have you had that bike over there? I’ve had it for three years. How long has his son owned the train and railway set? He’s owned it since his fourth birthday. Have you ever played football? Yes, I did when I was little, but I haven’t played for a while now. have own play have, own, play 是 动词。 延续性 1.I have been at this school___more than two years. 2.She has worked in the factory______ten years ago. 3.Mr. Green has lived in the city______he was born. 4.His father has been a party member____twenty years. 5.He has been a soldier _____ May, 2000. 6.His grandpa has been dead ____about ten years. for since since for since for since + （过去的）月份\年份\时间点 一段时间+ago 一般过去时从句 for +一段时间 延续性动词 在表示持续一段时间的句子中，应将短暂性动词转化为相同意义的延续性动词或状态动词。 初中英语中常见的有： 短暂性动词 延续性动词 go, leave, move arrive, come, reach join,  become buy, get (得到) be away (off),   be out of be here , be in +某地 be in,  be a (an) + n. have [拓展] 短暂性动词在肯定句、疑问句中不能与时间段连用，如become, begin, buy, borrow, arrive, come, die, fall, finish, go, join, leave, marry等。为了表述这种意思，我们常用相应的延续性动词have, keep等来代替非延续性动词。如： 我买这本书一周了。 I have bought the book for a week. (×) I have had the book for a week. (√) 20 Compare the sentences and tell True or False. 1. How long has he left? How long has he been away? 2. How long has he borrowed the book?

Tony has had the computer for two years. √ × √ × √ × √ × 非延续性动词可表示某一动作完成，因此可用于现在完成时； 但由于动作不能延续，所以不能跟表示一段时间点时间状语连用： Jim has come back. 汤姆已经回来了。 Jim has come back for a month. 汤姆已经回来了一个月。 2. 非延续性动词变成延续性动词，再与表一段时间的时间状语连用。 Jim has been back for a month. 汤姆已经回来了一个月。 Grammar X 3. 非延续性动词转化为延续性动词 1）直接换成延续性动词　 buy 买 → have 有　 borrow 借 → keep 保留　 put on 穿上 → wear 穿着 come / go / become 来/去/变成 → be 在/是 I have had the bike since I was 7. 我七岁就买了那辆自行车。 Grammar 2）转换成be＋名词 join the army 参军 → be a soldier 当兵 join the Party 入党 → be a Party member 成为一名党员 go to school 去上学 → be a student 成为一名学生 翻译：他已经上9年学了。 He has gone to school for 9 years.
