Unit8 Adventure-语法篇

_______________________________________________________________________________ _______________________________________________________________________________

1、认识，理解并掌握现在完成进行时 2、辨析现在完成时和现在完成进行时的区别 3、熟悉现在完成时和相关的时间状语

一、课时重点

1. 我们用现在完成进行时表示：

过去开始的反复或正在进行的动作。例如：

I've been going everywhere by bike for the last two years. 最近的过去开始的对现在有影响的动作。例如：

He's been doing his science project all night。（that's why he is so sleepy now） 形式：

现在完成进行时的构成是：主语+have/has+been+doing You have been studying very hard. Has Steve been complaining about it? 2. 现在完成时和现在完成进行时的辨析：

我们用现在完成时描述一个完成的动作（成果），用现在完成进行时谈论未完成的动作，例如：

I have read Hamlet （我已经读过了）

I have been reading Hamlet （我还没读完，一直在读）

现在完成时关注动作的结果，特别是谈到数字或数量时；现在完成进行时关注动作本身，特别是解释动作可见的结果时。例如：

He has run 3 miles. （强调跑完的距离）

He has been running for an hour. （强调动作和结果，如：过去的一个小时干了什么，以及现在为什么这么累） 3. 现在完成时和时间状语

现在完成时一般使用下列时间状语：before, ever, never, seldom, sometimes, often, usually, just 其中，already用于陈述句中，一般放在have后；yet用于疑问和否定句中，通常放在句末。例如：

I have already repaired my bike. Have you repaired your bike yet? I haven't repaired my bike yet. 关于for和since

for用于说明动作的时间长度，例如： I haven't seen him for ten years. since用于说明动作的起点，例如： I haven't seen him since 1990.
