本單元重點難點分析
1．have been (to) 與 have gone (to)
have been與have gone都表示現(xiàn)在完成時態(tài)，表明動作已經發(fā)生了，但它們之間的含義是有不同的。
1）"have been in + 地點名詞"或者"have been + 表位置的副詞"含義是"在某地呆得過多久"。例如：
Mr Zhang has been in this school for ten years．He knows everyone here.
張先生在這所學校呆了十年。
I have been here since I began to work．It's just like my home.
我工作以來一直呆在這里。
2）"have been to +地點名詞"表示"曾經到某地去過（多少次）"。例如：
Miss Brown has been to China twice．That's why she speaks Japanese very well.
布朗小姐來過中國兩次。
Have you ever been here before?
你以前到過這兒嗎？
3）"have gone to +地點名詞"或"have gone + 表位置的副詞"其含義是"到某地去了"（人已不在此地），注意：這種結構不用于第一人稱，也不用于第二人稱，它僅用于第三人稱。請看下面一段對話：
A: Where's Tom?
B: He's gone to the shop.
A: Has Mary gone there with him?
B: No, she hasn't.
A：湯姆在哪里？
B：他到商店去了。
A：瑪麗跟他去了嗎？
B：沒有。
2. Businessmen are afraid of newspapers and TV stations. 生意人害怕報紙和電臺。
be afraid of… 意思是"害怕……"。afraid是形容詞，在句中只能作表語，后跟名詞或動詞的-ing形式（指自己不能決定而突然發(fā)生的事），與frightened的意思相同。be afraid后也可跟動詞不定式表示"害怕做某事"即：be afraid to do sth.。另外，afraid后還可跟that引導的賓語從句，意思是"擔心，恐怕"。例如：
�。�1）I am afraid of mice. 我害怕老鼠。
（2）Don't be afraid of making mistakes. 不要怕犯錯誤。
�。�3）I'm afraid to tell her the truth. 我不敢告訴她真相。
�。�4）I am afraid you are ill. 恐怕你是病了。
�。�5 ）I'm afraid (that) we may not catch the train. 我擔心我們可能趕不上火車。
3. As soon as other people hear it, they go out with their rubbish and throw it in.
當人們一聽到它，他們就出來把垃圾扔進去。
as soon as -……就……，引導時間狀語從句，表示主句的動作緊跟從句的動作發(fā)生。必須注意 as soon as possible（one can），它表示"盡可能快地"。
【例】
�。�1）He'll write to me as soon as he gets to Beijing．
他一到北京就會給我寫信。
�。�2）You should do your work as soon as possible．
你應盡快地做事。
4. … taking care of our environment is very important. 保護好我們的環(huán)境是非常重要的。
(1) take care of保護，照顧，保管。如：
Please take good care of your books. 請保管好你們的書。
Can you take care of my baby while I'm away? 我出去時你能為我照顧我的孩子嗎？
(2) "Taking care of our environment" 在這里是動名詞短語作主語。也可以說： It's very important to take care of our environment.
5．It's our duty to keep our environment clean and tidy. 保持我們的環(huán)境干凈整潔是我們的責任。
�。�1）it在這里是形式主語，真正的主語是"to keep our environment clean and tidy"
又如：It's a pleasant way to help keep our city clean.
�。�2）keen后面可跟帶現(xiàn)在分詞的復合結構。如：
He kept me waiting for a long time yesterday．他昨天讓我等了很長時間。
keep后面也可跟帶形容詞的復合結構。如：
You should take more exercise to keep you healthy．你應該多運動來保持健康。
6．If everyone makes a contribution to protecting the environment, the world will become much more beautiful. 如果每人都對保護環(huán)境做出貢獻，那么世界將變得更加美麗。
make a contribution to…意思是"對……做貢獻，捐贈"。to是介詞后跟名詞或動詞的-ing形式。例如：
（l）Thomas made a great contribution to the world．托馬斯·愛迪生對世界做出了很大的貢獻。
（2）It is our duty to make a contribution to protecting the environment．為環(huán)境保護做貢獻是我們的責任。
make是英語中非常活躍的動詞之一，和不同的詞搭配具有不同的含義。又如：
make a face做鬼臉 make a living謀生
make a mistake犯錯誤 make friends with交朋友
make fun of開玩笑 make one's way擠出一條路
make room for讓座 make up one's mind下決心
My friend Emma made fun of my job once time. She said that my job is rather making a living than career manage. I made up my mind to run my company successfully, which could make her realize she had made such a mistake. Then I made my way in mass society. I made good as a manager. I stay here and make sure that I have made a go of the business. I make of what Emma have done for me, luckily, I made friend with her.
7. The more trees, the better的結構
這里是"the more，the more…"句型表述結構，它的意思是"越多越好；越……，越……"。例如：
Start your work, the sooner, the better.
開始工作吧，越快越好。
The more I think of it, the happier I am.
我越想越高興：
The harder you work, the greater progress you will make.
你越用功，進步就越大。
The longer we stayed there, the more we like the people there.
我們在那里呆得越久，越喜歡那里的人民。
注意：在"the more…，the more"這個句型中，"the"不能省略。
8．… need to do better in protecting the environment. 需要在保護環(huán)境方面做得更好。
do well in在某方面干得好。do better in在某方面干得更好。
在in后面加名詞或動名詞。例：
He does well in playing football．他足球踢得很好。
9．延續(xù)性動詞與非延續(xù)性動詞
(1) 延續(xù)性動詞
表示動作能夠持續(xù)發(fā)生一段時間的動詞。如：
be, have, know, work, live, study, teach, speak, talk, draw, wait, wear, walk, sleep等。
Miss Gao has been here since 7:00.
高小姐七點起就到這兒了。（此句中不能用arrived或come）
I have had the bike for five years．
這輛自行車我已經買了五年了。（不能用bought）
(2) 非延續(xù)性動詞
表示一個動作剛剛發(fā)生即告結束。如：
come, go, arrive, reach, see, hear, close, leave, begin, start, lose, fall, join, die, get up等。它們可以用于完成時態(tài)的第一種，說明某個動作的結果還存在。但它們不可以用于完成時態(tài)的第二種。
Grandpa Wang has died. 王大爺已經去世了。
The film has begun．電影已經開映。（現(xiàn)正放映）
這類動詞不能和表示一段時間的狀語連用。如：要表達"王大爺已經去世兩年了"應這樣寫：Grandpa Wang has been dead for two years. 而不能寫成：
Grandpa Wang has died for two years.
注：在for+時間段或 since+時間點的詞組或句子上進行畫線部分提問要用how long。同時用how long開始的句子中的謂語要用延續(xù)性的動詞（時態(tài)不限）。
關于現(xiàn)在完成時的講解
1．表示過去發(fā)生或己經完成的動作對現(xiàn)在造成的影響或結果
現(xiàn)在完成時的常用副詞是never"從來沒，不"，ever"曾經"，just"剛剛"，already"已經"，yet"已經，仍然"。其中already通常用有肯定句中，yet通常用在否定句和疑問句中。yet在否定句中要譯成"仍然"，"還"，在疑問句里要譯成"已經"。
�。�1）常already, just和yet等連用，如：
一Have you finished your work yet? 你做完你的工作了嗎?
一Yes. I have. I've just finished it. 我做完了，我剛做完。
I've already finished it. 我已經完成了。
I haven't finished it yet.我還沒做完。
�。�2）也可與ever, never連用
-Have you ever been to the park? 你曾去過那個公園嗎?
-Yes, I have. / No, I haven't, I have never been to the park.
是的，我去過。/不，我沒去過，我從未去過那個公園。
2．現(xiàn)在完成時與動詞的延續(xù)性
�。�1）for 和since時間狀語與現(xiàn)在完成時連用，表示從過去某一時間開始并一直延續(xù)到現(xiàn)在的情況，因此謂語部分不能用非延續(xù)性動詞，常見的非延續(xù)性動詞有：
close, leave, see, come, hear, buy, borrow, begin(start), join, die, finish等。
�。�2）在否定句中非延續(xù)性動詞可以與for或since引導的表示段時間的狀語連用，如：I haven't seen him for a long time.（此句是否定句，非延續(xù)性動詞see與for a long time連用）
3．注意現(xiàn)在完成時和一般過去時的區(qū)別。
A．一般過去時通常表示在過去某一具體時間發(fā)生的動作，與現(xiàn)在沒有什么聯(lián)系。現(xiàn)在完成時與現(xiàn)在有聯(lián)系，它表示過去的動作對現(xiàn)在產生的影響，結果。例如：
He cleaned the room an hour ago. 他一小時前打掃了房間。
He has cleaned the room. You see, it's very clean now.
他打掃了房間。你瞧，現(xiàn)在挺干凈的。
B．當句子有表示過去具體時間的狀語時，通常用一般過去時�，F(xiàn)在完成時不能與確定的過去時間狀語連用。例如：
We learned Lesson 4 last week. 我們上星期學了第4課。
不能用We have learned lesson 4 last week.
關于訓練聽說讀寫能力的教學建議
一、聽力訓練
除了課堂的聽力訓練以外，可以提供給學生一些關于現(xiàn)在完成時的聽力練習，完成一些替換練習、完成句子、回答問題等。在復習了前三單元內容的同時，還能達到了能讓學生聽懂相關語法的語句，并靈活運用現(xiàn)在完成時和一般過去時來回答問題。所涉及的范圍可以包括以時間點為線索的描述過去經歷、簡歷求職、假期生活等。 二、口語訓練
1. 看圖說話
向學生展示兩幅關于環(huán)境的圖片，其中，一幅是未受污染的環(huán)境，一幅是受污染的環(huán)境。讓學生觀察并對比它們，看看哪一幅beautiful，哪一幅是已受污染的環(huán)境。然后完成對Bad Environment和Good Environment的描述，以及人們曾對這種環(huán)境做過什么。
可提供下列詞匯與詞組：
pour, waste, dirty, clean, terrible, do no harm, write a book on the environment, pick up rubbish, collect rubbish, keep/make the place clean/dirty，damaged badly, in public place, it seems like, it is our duty to, plant tree, improve, recycle, make a contribution to，etc.
2. 簡述自己和他人的經歷
分兩步進行練習：
1) 讓學生們完成自己的簡歷，寫清楚時間、地點、當時所做的事情或身份。
2) 將學生分成兩組，A組和B組。兩組成員數(shù)量相同，并分別在對方組互相指定一名交談者。分別讓A組的成員向B組相對應的成員敘述自己的經歷，同時B組相應同學做好記錄，然后，B組同學復述A組同學的經歷。再分別交換角色，由B組敘述，A組復述。
注意提醒同學，一般過去時和現(xiàn)在完成時的使用應準確，敘述他人的經歷時，應注意他/她本人敘述時的用詞和所用時態(tài)。
三、閱讀訓練
在學習第10課的課文時，注意三種表述的不同用詞和語態(tài)：表述過去的事情、表述現(xiàn)在已完成或已產生的影響、下結論或展示希望�？勺寣W生閱讀后進行分析和歸納整理，將三種表述的用法和語言環(huán)境分別選出，形象地理解什么時候使用哪種時態(tài)是正確的。有代表性的句子有：
One day I was visiting … My friend said …
It is our duty … You might ask …
Have you ever thrown … Have I ever picked up
還可將本課有用的短語和詞組挑出來，進行造句練習：
a piece of beautiful music
pick up
collect rubbish
keep our city clean
take care of
throw onto
spit in a public place
cut down
protect our environment
make a contribution to
四、寫作訓練
1. 環(huán)境保護是個世界性的話題，它需要每個人來進行努力。除了對一些生態(tài)環(huán)境進行保護以外，還要保護我們身邊的環(huán)境。根據(jù)教材第10課的內容，將課文改寫成Protect our environment的百字短文。建議大家如何來保護我們的生活、工作或社會環(huán)境。除了課文所涉及的內容，可以加入自己的想法和建議。
2. 組織學生完成一份關于自己身邊環(huán)境的英文調查報告。提醒學生先準備好所要調查的項目，以及各項所需要的指標、數(shù)字、表格等。主題可包括水、空氣、土地、河流、資源、城市等。字數(shù)在80-100單詞。
可提供下列詞匯與短語：
waste water, clear air, earth, city, river, dirty, rubbish, spit, throw, collect, pick up, draw, damaged badly, in public place, it seems like, it is our duty to, plant tree, improve, recycle, make a contribution to, make/keep it clean, hope, wish, etc.
在總結時，建議根據(jù)不同的話題，將學生分成若干組，分別選出代表進行報告表演。鼓勵每個學生都積極參與，營造熱烈的報告氣氛，讓學生盡量用英文進行報告。在完成此報告時，學生們應掌握了關于環(huán)境保護的相關知識，意識到保護環(huán)境的重要性，并主動去宣傳相關知識。
3. 向學生展示三個場景的圖片或動畫：
1） 學生在學校內隨便亂扔東西，使校園看起來很臟；
2） 學生們在校園內很賣力地打掃衛(wèi)生；
3） 整個校園變得干凈整潔。
根據(jù)這三個場景完成作文《校園的變化》。

探究活動
調查報告
組織學生完成一份關于自己身邊環(huán)境的英文調查報告。提醒學生先準備好所要調查的項目，以及各項所需要的指標、數(shù)字、表格等。主題可包括水、空氣、土地、河流、資源、城市等。字數(shù)在80-100單詞。
可提供下列詞匯與短語：
waste water, clear air, earth, city, river, dirty, rubbish, spit, throw, collect, pick up, draw, damaged badly, in public place, it seems like, it is our duty to, plant tree, improve, recycle, make a contribution to, make/keep it clean, hope, wish, etc.
在總結時，建議根據(jù)不同的話題，將學生分成若干組，分別選出代表進行報告表演。鼓勵每個學生都積極參與，營造熱烈的報告氣氛，讓學生盡量用英文進行報告。在完成此報告時，學生們應掌握了關于環(huán)境保護的相關知識，意識到保護環(huán)境的重要性，并主動去宣傳相關知識。
改編課文
環(huán)境保護是個世界性的話題，它需要每個人來進行努力。除了對一些生態(tài)環(huán)境進行保護以外，還要保護我們身邊的環(huán)境。根據(jù)教材第10課的內容，將課文改寫成Protect our environment的百字短文。建議大家如何來保護我們的生活、工作或社會環(huán)境。除了課文所涉及的內容，可以加入自己的想法和建議。
簡述自己和他人的經歷
分兩步進行練習：
1. 讓學生們完成自己的簡歷，寫清楚時間、地點、當時所做的事情或身份。
2. 將學生分成兩組，A組和B組。兩組成員數(shù)量相同，并分別在對方組互相指定一名交談者。分別讓A組的成員向B組相對應的成員敘述自己的經歷，同時B組相應同學做好記錄，然后，B組同學復述A組同學的經歷。再分別交換角色，由B組敘述，A組復述。
注意提醒同學，一般過去時和現(xiàn)在完成時的使用應準確，敘述他人的經歷時，應注意他/她本人敘述時的用詞和所用時態(tài)。如把此練習放入課堂教學，可參考課件類素材《第9課教學演示中》的Presentation。
看圖說話
向學生展示兩幅關于環(huán)境的圖片，其中，一幅是未受污染的環(huán)境，一幅是受污染的環(huán)境。讓學生觀察并對比它們，看看哪一幅beautiful，哪一幅是 已受污染的環(huán)境。然后完成對Bad Environment和Good Environment的描 述，以及人們曾對這種環(huán)境做過什么。相關圖片提供在圖形圖像類素材。
可提供下列詞匯與詞組：
pour, waste, dirty, clean, terrible, do no harm, write a book on the environment, pick up rubbish, collect rubbish, keep/make the place clean/dirty，damaged badly, in public place, it seems like, it is our duty to, plant tree, improve, recycle, make a contribution to，etc.
