三、课堂导学
A）语法
1、现在完成时的定义：现在完成时通常是指过去某一动作对现在的影响或过去发生的某一动作持续到现在（可能要持续下去）
2现在完成时的句式构成：主语+have/has+动词的过去分词+（宾语）+（地点）+（时间）。
各种句式如下：
肯定句：I have lived in ShuYang for two years.
否定句：I have not lived in ShuYang for two years.
一般疑问句：Have you lived in ShuYang for two years?
肯定回答：Yes, I have. 否定回答：No, I haven’t
特殊疑问句：How long have you lived in ShuYang?
3、现在完成时的基本用法：
a. 现在完成时可表示过去发生的动作对现在所产生的影响，后面通常不用时间状语，但句中常出现 already ，just， yet 等副词。
如：有人把窗户打破了。Someone has broken the window.
我刚刚读完这本书。I have just finished reading the book.
他已经看过医生了。 He has already seen the doctor.
你看过医生了吗? Have you seen the doctor yet?
( 注意：already常用于肯定句中，置于句中。yet 常用于否定句和疑问句中，常用于句末。)
b)现在完成时也可表示从过去某时开始的动作或状态一直持续到现在，常和for, since 引导的时间状语连用。
注意：for和since 引导的时间状语从句的区别：for + 一段时间，since + 点的时间或从句（从句中常用过去时）
如：I have learned English for 5 years.
I have learned English since 5 years ago
She has worked here for three years
He has lived in Beijing since he was born.
They have lived in Su Yang since they moved here
c)、现在完成时也可表从过去到现在曾经经历过或做过的事情。常和often、ever、never、before、once,….等时间状语连用。
e.g: 我从没去过北京。I’ve never been to Beijing.
他以前读过这本书。He has read this book before.
