人教版八年级(下)英语第20讲：unit10语法篇
Unit 10 语法篇____________________________________________________________________________________________________________________________________________________________________学生通过本讲学习，能够掌握本单元的重点语法，并在综合能力上有一定的拓展。
现在完成时for，since用法1. 表示在过去开始一直延续到现在(可能延续下去)的动作或状态时,时间状语有：for (two years),since 1990, since (two weeks ago)和since引导的状语从句。
如：I have been away from my hometown for thirty years.(我离开家乡有30年了)Uncle Wang has worked in the factory since it opened.(自从这家工厂开张,王叔叔一直在那儿工作)2. 口语中have got往往表示have(有)的意思。
如：They have got thousands of books in their library.(他们图书馆有上万本书)3. have been to与have gone to的区别：have gone to(“已经去了”)表示人不在这里,have been to(“去过”)表示人在这里。
如：--Where is Mr Li? –He has gone to the UK.(李先生在哪里？他去了英国。
)--Do you know something about Beijing? –Yes, I have been to Beijing three times.(你知道北京的情况吗？是的,我去过那里三次。
)4. 在完成时中,一个瞬间性动词(一次性动作)不能与表示一段时间的状语连用,此时须将该瞬间动词改为延续性动词或状态动词。
八年级英语下册Unit 10 单元语法知识梳理
现在完成时（Ⅲ）1.现在完成时的“未完成用法”现在完成时表示动作或状态从过去某时开始，一直延续至今，还可能继续下去。
这种用法称为“未完成用法”。
此时常与for或since引导的时间状语（从句）连用。
表示“未完成”的句式示例现在完成时+for+一段时间We have known each other for twenty years.我们认识有二十年了。
I haven't seen her for a long time.我好久没有见到她了。
现在完成时+since+表示过去的时间点Mr. Smith has worked here since 1984.自1984年以来，史密斯先生就在这里工作。
现在完成时+since+从句He has learned about 5000 English words since he went to college.自上大学以来他学了大约5000个英语单词。
谓语动词用延续性动词，可以用how long提问。
例句：He has been a soldier for three years.他参军三年了。
→How long has he been a soldier? 他参军多长时间了？2.延续性动词与非延续性动词（1）延续性动词表示经验、经历；非延续性动词表示行为的结果，不能与表示一段时间的状语连用。
有些非延续性动词可以用延续性动词替换并用在现在完成时中。
（2）在现在完成时的句子中，若含有for或since引导的时间状语，则句中谓语一定要用延续性动词。
非延续性动词转换为延续性动词的方法有：①将非延续性动词转化为“be+形容词或副词”，这样才能和时间段连用：begin (start) →be on（开始）go there →be there（去哪里）come back →be back（回来）come here →be here（来这里）open →be open（开门）close →be closed（关门）die →be dead（死）marry →be married（结婚）finish →be over（结束）go to bed →be in bed（上床睡觉）leave →be away（离开）return →be back（回来）get out →be out（出去）fall asleep →be asleep（入睡）lose →be lost（丢失）fall ill →be ill（生病）get (arrive，reach) →be in / at（到达）join (become) →be in / be a member of（参加；加入）②有的非延续性动词可以转化为意思相同的延续性动词：borrow →keep（借）put on →wear / be on（穿）become →be（成为）get to know →know（认识）buy →have (own)（买）catch a cold →have a cold （感冒）receive →have（收到）go to sleep →sleep（睡觉）例句：They has been married for 6 years.他们已经结婚六周年了。
八下 U10 单元语法主题作文重点短语和必背句子
延续性动词与非延续性动词现在完成时表示从过去已经开始持续到现在的动作或状态，可以和表示“从过去某一时刻延续到现在的一段时间状语”连用，如“for+段时间”、“since+过去点时间”、“since+过去时的从句”、“since+一段时间+ago”。
且for与since引导的时间状语可以相互转换。
eg. I've had this bike for three years. = I've had this bike since three years ago. 我拥有这辆自行车三年了。
含有for，since的现在完成时: 过去的动作或状态，一直持续到现在。
句中动词的特点：表示持续性的动作或状态的动词必须是延续性动词(否定句除外)。
eg. He’s owned it since his fourth birthday. 他从四岁起就拥有了。
I have known Ann for three years/ since three years ago. 我认识安已经三年了。
非延续性动词和延续性动词之间的转换1) 转换为相应的延续性动词，用于现在完成时。
