1. to go over the knowledge in unit 1
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
二、短語運(yùn)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。
