3. 能够在语境中正确运用现在完成时。
4. 运用现在完成时谈论发生在过去并与现在有联系的事情。
二.预习指导:

预习任务:
1、我们已经学习了动词过去时的变化规则,你能说出有几种变化吗?
2、想一想我们已经学习了几种时态?能不能每一种时态各举一个例子。

三.课内探究:
现在完成时的“完成用法”和“未完成用法”
一) 现在完成时的结构: have / has + 动词的过去分词
其中 have / has 为助动词,它的否定和疑问句形式全部由 have / has 进行变化。
例如: 1. He has finished his homework.他已经做完了家庭作业。
否定句:____________________________________________________
一般疑问句:________________________________________________?
2. His father has been to Beijing three times. 他父亲去过北京三次了。
否定句:____________________________________________________.
一般疑问句:________________________________________________?
对划线部分提问_____________________________________________?
二)1.现在完成时的"完成用法"
A、定义:现在完成时的"完成用法"指的是动作发生在过去某一时刻并已结束,
但该动作对现在产生了影响,与现在情况具有因果关系。
例如:He has turned off the light. 他已把灯关了。
( 动作结束于过去,但说明的是现在的情况:灯现在不亮了。)
B、特点:现在完成时"完成用法"的特点是动作不延续,因此,该时
态只能与表示不定的过去时间状语(如:already,yet,before,recently
等)、频度时间状语(如:never,ever,once等)、包括现在时刻在内的
时间状语(如:this morning / month /year...,today等)连用。
例如: Have you found your pen yet? 你已找到你的钢笔了吗?
用所给动词的适当形式填空(题目有点多但特别重要请认真做哦)
