教学过程

二、短语运用:in fact,get married,turn into,noise pollution,take off,in some ways,from time to time,be in service/use,free time,on one's own,on longer,the changes to;

三、重点结构:It is easy for him to see them as often as before.

It was built to the north of Lantau Island.

I wish you ahappy holiday.

It no longer provides agood environment for wildlife.

The changes have brought many benefits but they have also caused many problems for wildlife.

四、语法:现在完成时,present perfect tense 1、现在完成时所表示的动作发生在过去,但考虑较多的不是动作发生在过去的什么时候,而是强调与目前的联系,即过去与现在的关系。强调过去的动作对目前造成的影响和后果,或强调动作本身或状态持续地现在,因此属于现在时范畴。它的主要用法可概括为八个字:影响、结果、持续和经历。

2、现在完成时的构成:

肯定式:I/We/you/they have+been/worked she/he/it has+been/worked

否定式:have not+been/worked has not+been/worked

疑问式:Have+主语+been/worked…?

Has+主语+been/worked…?

3、现在完成时的用法

(1)表示过去发生的某一动作对现在生成的影响或结果。

如:He has read the book.他已经读过这本书了。

"读书"是发生在过去的动作,对现在造成的结果是"读过了"。

(2)表示动作过去已经开始,持续到现在,可能还要继续下去。这时往往与表示一段时间的状语连用。

如:He has worked for more than three years.他工作三年多了。

I have been in Suzhou for ten years.我来苏州已经十年了。

(3)现在完成时属于现在时态范畴,不能和表示过去的时间状语连用,如yesterday,last week,a day ago等。但可以和never,ever,already,yet,just(刚刚),for…,since…,in the past three years,so far(到目前为止),by now,before(以前)等连用。

如:Have you finished your picture yet?你已经完成你的画了吗?

I have never heard of him before.过去我从未听说过他。

(4)瞬间动词也叫短暂性动词。这种动词动作开始也就意味着结束,所以不能与表示一段时间的状语连用。这些动词是become,begin,start,buy,borrow,arrive,come,die,fall,finish,go,join,leave,marry等。这了表述这种意思,我们常用相应的延续性动词have,keep等或短语"be+名词/形容词/位置副词/介词短语"来代替短暂性动词。

如:He has kept the book for three weeks.这本书他已借了三周了。

The meeting has been on for half an hour.会已开始半小时了。

He has been in the army for three years.他参军三年了。

(5)其他词组的区别

①since和for的区别

since短语或从句表示过去的动作延续至今,since之后为时间点。

如:He has lived here since 2000.2000年以来他一直住在这儿。

I haven't seen him since ten years ago.自十年前开始我就没见过他。

I have known him since Iwas very young.我很小时就认识他了。

For短语表示动作延续多长时间,for后面跟时间段。

如:He has lived here for three years.他住这儿已经三年了。

I haven't seen her for along time.我已经好久没见到她了。

②have/has been in,have/has been to和have/has gone to的区别

have/has been in表示"在某地呆了多久了",可以与表示一段时间的状语连用。Have/has been to表示"曾到过某地(已回来)",不能与一段时间的状语连用。两者表示的意义不同,所以跟的时间状语也不同。

如:He has been to Guangzhou twice.他去过广州两次。

He has been in Guangzhou for along time.他在广州已呆了很长时间了。

have/has gone to意为"到某地去了(还没回来)",表示到了某地或正在去的途中。总之,说话时当事人不在现场,一般不用第一、第二人称代词作句子的主语。

如:-Where is Kate?凯特在哪儿?

-She has gone to the post office.她去邮局了。
