教學(xué)重點(diǎn)和難點(diǎn)
1. present perfect tense and some words and expressions
教學(xué)過程
一、重點(diǎn)單詞:just, since, fact, turn, miss, pleasant, land, way, lonely, lucky, grandpa, unkind, impolite, over, unhealthy

三、重點(diǎn)結(jié)構(gòu):it is easy for him to see them as often as before.
it was built to the north of lantau island.
i wish you a happy holiday.
it no longer provides a good environment for wildlife.
the changes have brought many benefits but they have also caused many problems for wildlife.
四、語法:現(xiàn)在完成時,present perfect tense
1、現(xiàn)在完成時所表示的動作發(fā)生在過去,但考慮較多的不是動作發(fā)生在過去的什么時候,而是強(qiáng)調(diào)與目前的聯(lián)系,即過去與現(xiàn)在的關(guān)系。強(qiáng)調(diào)過去的動作對目前造成的影響和后果,或強(qiáng)調(diào)動作本身或狀態(tài)持續(xù)地現(xiàn)在,因此屬于現(xiàn)在時范疇。它的主要用法可概括為八個字:影響、結(jié)果、持續(xù)和經(jīng)歷。
2、現(xiàn)在完成時的構(gòu)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
疑問式:have +主語+been/worked …?
has + 主語+ been/worked…?
3、現(xiàn)在完成時的用法
(1) 表示過去發(fā)生的某一動作對現(xiàn)在生成的影響或結(jié)果。
如:he has read the book.他已經(jīng)讀過這本書了。
“讀書”是發(fā)生在過去的動作,對現(xiàn)在造成的結(jié)果是“讀過了”。
(2) 表示動作過去已經(jīng)開始,持續(xù)到現(xiàn)在,可能還要繼續(xù)下去。這時往往與表示一段時間的狀語連用。
如:he has worked for more than three years. 他工作三年多了。
i have been in suzhou for ten years. 我來蘇州已經(jīng)十年了。
(3) 現(xiàn)在完成時屬于現(xiàn)在時態(tài)范疇,不能和表示過去的時間狀語連用,如yesterday, last week, a day ago等。但可以和never, ever, already, yet, just(剛剛), for…, since…, in the past three years, so far(到目前為止), by now, before(以前)等連用。
