Unit 8 Have you read Treasure Island yet?

第一课时 (Section A 1a-2d)

学习目标

1.学会用现在完成时表达过去发生的但与现在情况有关的事情。 2.掌握现在完成时结构和了解其含义

3.学会区分现在完成时与一般过去时的区别。

重难点

1现在完成时:表示过去发生或已经完成的动作对现在造成的影响或结果。 2现在完成时的构成：have/has +过去分词自主预习

一．动词过去分词的变化规则。

二．阅读课文57-58页的内容，试着找出下列短语的翻译。

1.充满_____________________ 2.赶快；匆忙（做某事）_________________ 3.成长；长大_________________ 4.在25页________________ 5.出海_____________________ 6.至少_________________ 7.英国 8.爱不释手______________ 9.书的后面 _____________ 合作探究

1.现在完成时：

1)含义：表示动作过去发生，但与现在有联系或影响，此时态常与以下时间词连用，如already已经,yet已经，还，just刚刚,ever曾经,so far到目前为止,before从前,times次数,for+时间段，since自从…以来,how long多久，never从不，in the past….在过去….

2)结构：主语+have/has+动词的过去分词（have/has是助动词，没有“有”的意义）

肯定句：She has finished her work.她完成了她的工作。

一般疑问句:-Has she finished her work?-Yes,she has./No,she,hasn’t. 否定句: She hasn’t finished her work.

3)动词的过去分词的构成：规则动词的过去式就是过去分词，不规则动词的过去分词见不规则动词表。

4）现在完成时态与一般过去时的区别：句子中如有yesterday,last,just now,in1999等过去时间词出现就只用一般过去时。

5)特别提醒：句子中如有when出现，一定不能用完成时例题：A:Jack has read the book, B:When did he read it? A:Last weekend

2.Have you read Little Woman yet?你已读过《小妇人》吗？

Yet（已经，还）的用法：在现在完成时中，already(已经)用于肯定句，yet用于一般疑问句或否定句，

例句：肯定句：I have already eaten lunch.我已经吃过午饭了。一般疑问句：____ you eaten lunch ____? 否定句： I _____eaten lunch ____.

3.What’s it like?它（这本书）怎么样？What+be+sth. like?表示“某物怎样？” 达标测评

1.I_______ ever________(drink)coffee.
