________________________________ ________________________________ （扎实基础，熟能生巧！）高一上期 module 4 ：重点语法现在完成时态（8 月8日，第八次课内容）现在完成时态是高考的常考点之一,它易与一般过去时态混淆。
一：结构形式：_________________________( 与动词连用)_________________________( 与形容词连用)二、现在完成时态的用法1. 表示继续：表示继续意义旨在说明过去的动作一直延续到现在,也就是说从过去某时开始的动作或状态一直持续到现在。
如:We have talked on the Internet since a year ago.Our class have prepared for the party all this week.注意:表示继续的现在完成时态多与表示一段时间的时间状语连用。
常用的这类时间状语有:for + 时间段,since ＋时间点,how long, _________/________( 最近_________( 总是) _____________( 一直)_________________/_______________ (直到目前)，_____________________ ( 最近几年以来 ) 等。
2. 表示经验：说明从过去到现在的经验,即从过去到现在这段时间之间曾经经历过或做过的事情。
（与次数连用多）， ________( 以前) 如:I have been to New York three times.I have taught English in a primary school before.3. 表示完成：有时意为"刚做完……"或"做完了……",表示过去开始的动作现在刚刚结束。
时间状语______________( 刚刚。
)如:I’ve just finished watching the movie.My mother has just gone to Changsha.4. 表示结果：用来强调过去的动作对现在仍有影响。
如:Electricity(电)has made our life colorful.I have lost my wallet.注意:表示结果的完成时往往不必用时间状语。
二、现在完成时态和一般过去时态的区别使用现在完成时态重在说明现在的情况,表示过去与现在的关系,强调结果；一般过去时则只涉及过去的行为或状态本身。
所以说话人要表达的侧重点不同,要用的时态就不同。
试比较:Have you had your lunch?(侧重_________的情况)Did you have your lunch?(强调__________的行为)The old man has lived in Beijing for over 20 years.(那个老人现在还活着,现在还住在北京或者刚离开)The old man lived in Beijing for over 20 years.(那个老人现在已故去)三．熟悉现在完成时态的各种句型（肯定句，否定句，一般疑问句，特殊疑问句）。
Tom has just gone to Changsha.否定句：_______________________________一般疑问句：_________________________________________肯定回答__________________否定回答_________________________特殊疑问句：_____________________________(对changsha 提问)I have been to New York three times.（对划线部分提问）_________________________________________________________________We have talked on the Internet since a year ago.（对划线部分提问）_________________________________________________________________I have lost my wallet. （对划线部分提问）__________________________________________________________________ 四．翻译练习：1.最近，你在做什么？_______________________________________________2.我以前见过那个人。
_______________________________________________3.我去过北京三次了。
_______________________________________________4.我已经学习英语4年了。
____________________________________________5.自从我到这儿，已经教英语12年了。
_____________________________________6.这是我第一次来美国。
______________________________________________。
