英語 Waste 內容全析

【本課教學目標】

　　相關知識

　　本單元 30 和 31 兩課的學習中要掌握下列線索：

　　1．Why must we stop pollution?

　　2．What kind of pollution is mentioned in the text ?

　　3．What types of waste are discussed in the text ?

　　4．Can you tell what ways are used in the world to recycle waste ?

　　5．How many different things are reused in China?

　　句子分析

　　1．No matter how much you want to bathe，it just isn’t safe．　　不管你多么想洗海水澡，反正這都很不安全。

　　這里是由 no matter how 引出讓步狀語從句。

　　但是一定要注意：no matter how(however) 既可以接形容詞和副詞，表示程度狀語；又可以直接接句子，表示方式狀語。請對比下面兩個句子：例如：

　　No matter how small the wheat ear is，we should pick it up．　　無論麥穗有多小，我們都該把它拾起來。(程度狀語)

　　No matter how he tried，he failed at all．　　無論他怎樣試，他均未成功。(方式狀語)

　　No matter 之后可以是任何 wh-word 例如：what，who，which，when，where 等。例如：

　　No matter what she says ，he wouldn’t listen to her.　　不管她說什么，他就是不聽她的。

　　No matter who says it，he wouldn’t listen．　　不管誰說的，他就是不聽。

　　No mater where he works，he is always working hard.　　無論他在哪兒干活，他總是很賣力氣。

　　2．When you find anything，make a note where it’s found and do a drawing in your notebook．

　　當你發現某種東西時，記下發現的地點，并在筆記本上繪一個圖。

　　該句子中 where it’s found 為同位語從句，說明 note 的內容。

　　注意：不要把它看成是地點狀語從句，那就譯為“在你發現它的地方做筆記”意思完全不對了。where it’s found，不是指 make a note 的地點。

　　該句中有一個搭配很強的結構： 　　do + (由動詞轉換來的) ing 式，表示做什么。例如：

　　do a drawing 繪一個圖

　　do some cooking 做飯 do some shopping 買東西

　　do some reading 閱讀 do some writing 寫東西

　　3．How to get rid of waste is a great problem for the world today．如何處理廢物是當今世界上的一個大難題。

　　該句是不定式結構做主語。How to get rid of waste 是由疑問詞+不定式構成。它可以延伸為一個主語從句：

　　How we should get rid of waste．

　　疑問詞+不定式結構可在句中做主語，賓語，表語等。例如：

　　How to deal with the matter is unknown．　　如何處理這件事沒有人知道。(作主語)

　　We haven’t decided when to start off for Beijing．　　我們還沒有決定何時動身去北京。(做賓語)

　　The problem is how to get rid of bad habit．　　問題是如何去掉這不良的習慣。(做表語)

　　4．A better method is to take the waste far out to sea in ships where the wind and waves break it down．

　　該句中“where the wind and waves break it down”為定語從句，先行詞為sea．句中 break down 做“分解”講。(既可以指化學變化，也可以指物理變化)。

　　5．It will be many years before the chemicals start to escape from the containers.

　　要過很多年(之后)，容器里的化學物質才會開始流出。

　　該句中 before 譯為“在(一段時間)之后”。例如：

　　It was three months before she returned to her hometown．　　三個月之后她才返回家鄉。

　　注意：在翻譯含有 before 從句的句子時，要注意漢語的譯法。例如：

　　Before I could get in a word，she had left without saying a word．　　我還沒來得及插話她便什么也沒說就走了。

　　It was not long before the whole country rose up.　　沒過多久，全國就舉行了起義。

　　翻譯下列各句，注意 before 的譯法：

　　1．Do it now before you forget．

　　2．Before I could get in a word，she had left．

　　3．It was not long before she came back．

　　4．It was long before she came back．

　　5．He had left the town the day before she arrived．

　　6．It will not be long before they understand each other．

　　參考答案：

　　1．趁你沒忘記，趕快做這件事。(否定譯法)

　　2．我還沒來得及插話，她便走了。(否定譯法)

　　3．沒過多久，她便回來了。(不譯)

　　4．過了好久之后，她才回來。(譯為“之后”)

　　5．她到的前一天，他就離開這座城市了。

　　6．要不了多久，他們便會彼此理解了。

　　語言要點

　　1．deal with 作：“處理”講。例如： 　　Pollution is a big problem to deal with．　　污染是一個要處理的大問題。

　　I wonder how we should deal with so much rubbish．我不知道如何處理這么多的垃圾。

　　2．Although the sea breaks up the waste...　　雖然海洋可以把糞便沖散……

　　break up 作“驅散”“拆開”“打碎”解。

　　做“拆散”解時，與 break down 同義。例如：

　　The war broke up many families．　　這場戰爭拆散了許多家庭。

　　The warship was broken up．這艘戰艦被拆散。

　　3．...depending on the nature of the materials．　　……視材料的性質而定。

　　depend on 做“依……而定，”“依靠”“依賴”講。例如：

　　Whether we’ll go there depends on the weather．我們是否去那兒取決于天氣。

　　4．at one time 譯為“(過去)有段時期”( once／in the past )例如：

　　At one time，he was an English teacher．過去有段時間，他是英語教員。

　　注意：at one time 不能與“at a time”混淆。

　　at a time 意思是“一次”“同時”例如：

　　We cannot do two things at a time．我們不能同時做兩件事。

　　5．...and has been very active in protecting the Pacific Ocean．在保護太平洋的活動中一直都很積極。

　　be active in 意思是“積極／主動地參加(活動)。”例如：

　　She has been active in sports．她一直積極參加體育活動。

　　We should be active in social activities．我們應積極參加社會活動。

　　6．European countries are making an active effort to reuse materials more than they used to．

　　歐洲國家現在正積極努力比過去更多地回收利用舊材料。

　　make an effort to do sth．努力做……

　　We have made every effort to fight against pollution．　　我們盡一切努力和污染做斗爭。

　　7．This ink is taken out by a special technique，and new paper is made．

　　用一種特殊的技術清洗掉油墨，再制成新的紙張。

　　take out ( = remove)擦掉，洗掉。例如：

　　How can I take out the ink marks from my new white shirt?　　我的白色新襯衣上的墨水怎樣才能洗掉呢?

　　They took out the posters on the walls．他們洗掉了墻上的招貼畫。

【重點難點解析】

　　新知講解

　　狀語從句

　　狀語從句在高三課本中雖然沒有單獨列出作為語法項目，但在本單元中狀語從句出現得比較頻繁，故引起大家的注意。

　　狀語從句在句中作狀語，修飾主句中的動詞，形容詞，副詞或整個句子。狀語從句由從屬連詞引導，既可放在主句前又可放在主句后。放在句首時，從句后經常用逗號；放在句尾時，從句前不用逗號。狀語從句共有：時間狀語、原因狀語、目的狀語、結果狀語、方式狀語、讓步狀語和條件狀語從句。無論什么樣的狀語從句，最主要的是要搞清連接詞的分類和

　　在從句中所起的作用，這是掌握狀語從句的關鍵。

　　舊知歸納

　　典題剖析

　　1．I was about to go for a walk ______ it began to rain．

　　A．while B．after C．when D．the moment

　　誤點 A 與 B 沒有掌握時間狀語從句中連詞的使用；同時對這個句子沒有充分的認識。正確答案應選：C。

　　解析 (1)首先要解決一個誤區問題：這道題不是大家所認為的狀語從句的概念。when 放在句中，前面的句子里有 be doing，be about to do，had just done，be ready to，be on the point of doing 時此句為一個并列句，中文的翻譯是：這時(突然)。

　　(2)引導時間狀語從句的連接詞有：

　　when：從句的動作可以與主句的動作同時發生，也可以有動作的先后，但是經常會有一個句子為進行時態。

　　as：作為時間狀語從句的連接詞時一般放在句中，前后的時態為一致翻譯為：“一邊……一邊……”；但是當 just as 出現時，要放在句首，翻譯為“就在……的時候”。

　　while：A．當作為從屬連詞時從句要用表示延續性的動詞，而 when 兩者皆可；B．當作為并列連詞時它要放在中間，前后時態要一致，同時用兩個不同的主語表示對比的概念。

　　before：表示“在……之前”。但有時它有不同的翻譯意思或有句型的概念。例如：

　　Don’t get off before the bus has stopped．

　　車沒停，不要下。(逆翻)

　　Three years had passed by before we knew it.

　　不知不覺，過去了三年。(逆翻)

　　The roof had fallen in before I could have time to save the boy．

　　我還沒來得及有時間去救那男孩，屋頂就塌了。(逆翻)

　　It was twenty days before he came back to his motherland．

　　二十年后，他回到了祖國的懷抱。(順翻，不譯)

　　after：表示“在……之后”

　　since：表示“自從……”。主句現在完成時態，從句一般過去時態。

　　as soon as，the moment，the minute，directly，immediately，Hardly had...when，No sooner had...than，Scarcely had...when：

　　均表示“一……就……”(但只有as soon as可以用在一般將來時態中)。

　　not...until，until／till：表示“直到……才”；“直到……”(前者主句動詞要用非延續性動詞，而后者要用延續性動詞)。

　　捷徑 重點掌握狀語從句的使用及連接詞的概念，并在具體的語言邏輯的要求下指導做題是解決狀語從句學習的關鍵所在．

　　2．______ he is busy，I won’t trouble him．

　　A．Since B．For C．When D．Unless

　　誤點 B選項是受到中文語言邏輯的直接影響的結果，since 與 for在表示原因時各有不同。正確答案應選：A。

　　解析 (1)在表示原因概念的時候首先要注意 since，as，for，be-cause 這幾個詞的區別。

　　since：“既然”，在使用時一定要注意主句的表達概念。例如：

　　Since everyone is here，1et’s have our meeting．

　　Since the earth is round，why can’t we fall off?

　　(主句所表達的是“建議性或無須回答的推測概念”)

　　because：“因為……；由于”，在使用時要注意它是表示主句動作的直接原因或用來回答 why 所引起的提問，既可放在句首，又可放在句中。例如：

　　Because he was ill，he didn’t come to the meeting last week．

　　-Why didn’t he come for a film?- Because he had seen it．

　　as：表示較為明顯的原因，除了可從外表看出原因以外，它不能回答由 why 引起的提問，既可放在句首，又可放在句中。例如：

　　As the weather was nice，I opened all the windows．　　顯而易見，天氣很好，我打開了窗戶。

　　As our country is strong，we are respected by people all over the world．

　　顯而易見，我們的國家強大了，備受全世界人們的尊敬。

　　for：在表示原因的時候它主要用于并列句里，同時要放在句中表示一種補充說明的原因(句子不能倒過來翻譯)，前面的句子里往往有：must，can，seem，look，can’t 等詞的判斷點的出現。例如：

　　He must have come from Africa，for he is black．　　他準是來自于非洲，因為他是個黑人。

　　(2)另外，還要掌握下面狀語從句的各種連接詞的使用。

　　①時間狀語從句：when，while，as，before，after，once，since，as soon as，wherever( = every time).till，until，by the time，every time．

　　②原因狀語從句：because，since，now that，as．

　　③條件狀語從句：if unless，as(so)long as，in case，on condition that，once．

　　④程度、結果狀語從句：so...that；such...that．

　　⑤讓步狀語從句：although, though, even if, even though, whatever, whoever, whichever, whenever, wherever, however, no matter what, no matter who,no matter when, no matter where, no matter how, as whether... or.

　　⑥目的狀語從句: so that, in order that.

　　⑦比較狀語從句: as... as, (not) so ... as, than, more than.

　　⑧方式、方法狀語從句: as, as if, as though, just as.

　　⑨地點狀語從句: where, wherever.

　　捷徑 注意掌握中英文之間的辨析與狀語從句所表達的確切含義是作好這類題的關鍵。

　　重點詞語辨析

　　1．used to 和 be used to 的區別

　　(1)be used to 是“習慣于……”的意思。其中 to 是介詞，后面可跟名詞或動詞的-ing 形式。例如：

　　He is used to this kind of job．他習慣于這種工作。

　　I am not used to getting up early．我不習慣于早起。

　　注：此短語中的 be 動詞有時候還可以換用 get 或 become。例如：

　　You will soon get used to our way of living．

　　你將很快習慣于我們的生活方式。

　　(2) used to 作“過去常常”解，表示“過去經常做某事”，含“現在已經不做此事了”的意思。這里的 to 是不定式符號，后跟動詞原形。be used to 作“習慣于”解，其中 to 是介詞，be 可以有不同的時態變化(過去時、現在時、將來時)試比較：

　　She used to go to the park in the morning．

　　她過去早上常去公園。(現在已不去了)

　　She is used to going to the park in the morning．她習慣于早上去公園。

　　(2)add... to... 意為“把……加入到……，增加，加進去”。如本單元中出現的句子：

　　Chaplin’s earliest films were silent，because the equipment for adding sound to films had not yet been developed．

　　卓別林最早期的電影是無聲電影，因為在那時還沒有研制出給影片配音的設備。

　　If you add five to eight，you will get l3．

　　(3)add to 意為“增添，增加，增進”。例如：

　　Your carelessness added to our difficulties．

　　(4)add up to 意為“總計，加起來總共是”，該短語不可用于被動語態。例如：

　　The expenses add up to $ 100．支出合計為一百美元。

　　3．set off (out)；set up；be set；set sb．free

　　(1)set off 表示“起程”、“動身”，后面可跟介詞 for，set out 也可表示此意。例如：

　　What time shall we have to set off tomorrow?

　　They set off for Beijing．

　　(2)set up 作“建立”、“成立”解。本單元出現過的句子：

　　In 1919，Chaplin set up an important film company.

　　(3)be set 的意思是“以……為背景”，“(戲劇影片)的背景是”，后面常跟介詞 in。

　　The film was set in California in the middle of the nineteenth century．

　　這部影片的背景是19世紀中葉的加利福尼亞。

　　(4) set sb．／sth．free 意為“給……自由”、“釋放”例如：

　　The slaves were set free a century ago，but the black people are still not given their full human rights．一個世紀前這些奴隸獲得了自由，但是黑人仍沒得到完整的人權。

　　You should set the poor bird free．

　　4．be known for；be known as；be known to

　　(1)be known for 表示原因，意為“因……而出名”。主語本身并非出名的原因，而是由于介詞 for 后的某物或某一地點特征等出名。主語和介詞后的內容不對等。例如：

　　Guilin is known for its beautiful scenery．桂林以優美的風景而出名。

　　(2)be known as 表示“以(作為)……而出名”，介詞 as 后常接人或事物，主語是出名的人或事物。兩者屬于對等的同位關系。例如：

　　She is well known as an excellent player．她作為優秀運動員而出名。

　　Gold was discovered in California and thousands of people rushed there to look for gold，so it became known as“the gold rush”．

　　有人在加州發現了黃金，成千上萬的人急急忙忙地跑到那里去尋找金子，于是這種熱鬧場面就成為人們所熟知的“淘金熱”。

　　(3)be known to 為(某人)所知或所熟悉，to 后跟表示人的名詞或代詞。例如：

　　He is always ready to help others，as is known to all．

　　5．still，quiet，silent，calm 的辨析

　　這幾個詞均表示“冷靜”、“平靜”，但內涵有別。

　　(1) still 主要指“靜止”、“不動”，可以指環境的安靜，也可指姿勢保持不動，強調沒有動作。例如：

　　The little girl stood still，except that her lips moved slightly．

　　那個小女孩一動不動地站著，只是嘴唇微微動了動。

　　How still everything is! 一切是多么安靜啊!

　　Still waters run deep．靜水流深(大智若愚)。

　　(2) quiet 主要指“安靜”，強調沒有聲音或動作；也指性情溫和、安詳、文靜或生活悠閑，環境寂靜、平靜。例如：

　　He has always lived a quiet life．

　　他一直過著悠閑的生活。

　　She is a quiet girl．她是個文靜的女孩。

　　(3) silent 指“沉默”，強調不發表意見；也指“寂靜”，強調沒有聲音。例如：

　　He said he could not keep silent any longer．

　　他說他再也不能保持沉默了。

　　The hall was silent．大廳內鴉雀無聲。

　　(4) calm“平靜”、“鎮定”，既可表示外界的安靜，又可表示內心的鎮靜。例如：

　　He remained calm in face of the danger．

　　面對危險他鎮定自若。

　　The sea was fairly calm，and I could see all about．

　　大海風平浪靜，我能看到周圍的一切。

【單元口語交際】

　　表示“禁止和警告”和“猜測”的句式 Prohibition and Warning and Conjecture

　　常用句型：

　　Don’t look out of the window．

　　You shall listen to your parents．

　　Never pour oil on water．

　　No smoking!

　　Don’t rush! 　　It seems that he is coming tonight．

　　He is likely to win the game in the end．

　　He must have finished the work．

　　What could they be talking about over there with the headmaster?

　　Mary can’t have gone to New York．I saw her just now seated under the tree，reading a book． 　　It looks as if is going to rain soon．

　　He appears to be an honest student in the class．But in actual fact，he isn’t．

　　口語示范：

　　1．表示“禁止、警告”及“猜測”的對話練習：

　　(1)Less noise，please ! - No noise，please ! (請小聲點!)

　　這是對話中的一個省略句。完整的句子為：

　　Don’t make any noise，please ! 或 Do make no (less)noise，please !

　　例如：Less noise，please．I have something important to tell you．

　　(請聲音小點。我有重要的事情告訴大家。)

　　No noise，please．The baby is sleeping．

　　(別吵了，孩子在睡覺。)

　　(2)Don’t rush ! (不要趕忙／不要性急)

　　它是由 Don’t + 原形動詞構成的表示“禁止”或“警告”的句式。

　　例1 -We’ve got to start off right now．

　　 -Don’t rush ! There’s plenty of time．

　　 -我們得馬上出發。-別急，時間還多著呢。

　　例2 -Let me get to the front．

　　　　 -Don’t crowd，please．

　　 -讓我到前面去。

　　 -請不要擠。

　　例3 -He hasn’t turned up now．

　　 -Don’t worry．He must be on the way here．

　　 -他現在還沒來。

　　2．It seems that there is a big waste pipe coming down from the town．

　　看來，有一根大廢水管從城里直接到這兒來了。

　　It looks as if our class won’t be able to bathe at all ．

　　看來，我們班(好像)根本不能洗海水浴了。

　　這兩句都是表示“猜測”的句子。

　　例1 -It’s already half past ten．There is likely no bus．

　　 -Well，it looks as if we shall have to walk home．

　　 -已經十點半了。不可能有公共汽車了。

　　 -唉，看來我們只得走回家了。

　　例2 -Relief supplies are being sent to the flooded areas．

　　 -It looks as if the situation will get better．

　　 -救濟物資正運往山區。

　　 -看來情況將會好轉。

　　例3 -They all say it is a good idea．

　　 -他們都說這個主意很好。

　　 -看來(似乎)沒有人反對這個意見。

　　例4 -He looks so happy．

　　 -他看上去很高興。

　　 一看來他已經上大學了。

　　英語解題中的斷句問題與判斷的技能培養

　　斷句包含兩層含義：意群停頓及深層次語法結構。會斷句，不僅可以使我們正確理解文意，還可以在解題時避免干擾，迅速得到正確答案。例如：

　　1．She did everything she could ______ help him．

　　A．do B．doing C．to D．to do

　　如果不能判斷 she could 是 everything 的定語從句(省略了 do)，則易選干擾項 A，而實際上這里的 help him 是做句子的目的狀語。所以只能選 C。

　　2．Please tell me the way you thought of ______ care of the garden．

　　A．taking B．to take C．take D．takes

　　首先判斷第一個 of 處是斷句，因為有短語 think of a way(to do／doing)sth，所以 the way 是 you thought of 定語從句的先行詞，而 to take 用作后置定語，修飾 the way。正確應選B。

　　3．Is there a tailor’s shop around ______ I can make a suit?

　　A．which B．what C．that D．where

　　很容易理解成 around which，而選 A。其實 around 在這里不是介詞而是副詞，相當于 about，做地點狀語，意思是“附近”，故選D。

　　4．The theory he’s stuck ______ us that earthquakes can be forecast．

　　A．to prove to B．to proves to 　　C．proves to D．which proved

　　這里考查 stick to 和 prove sth to sb 的用法。此句包含一個定語從句he’s stuck to ；一個賓語從句 prove to sb that earthquakes can be forecast 翻譯成：“他堅持的理論向我們證明了地震可以被預測”。斷句應在充分理解句意的基礎上進行，即在 stuck to 后。B 為正確答案。

　　5．The theory objected ______ true．

　　A．to prove B．proved C．to proved D．was proved

　　答案：C應從 to 和 proved 中間斷句，objected to 是后置定語，修飾 theory，proved true 為謂語。

　　6．Her boyfriend called not only herself but also her husband．Nothing she did to stop him ______.

　　A．working B．work C．worked D．works

　　由文章題意知，她采取了很多辦法來 stop him，但都不奏效。此句用定語從句 she did to stop him 來修飾，worked 是作句子的謂語，應從 worked 之前斷句。選C。

　　7．______ at the news that I didn’t know what to say to comfort her．

　　A．So sad she looked B．So sad did she look　　C．So sadly she looked D．So sadly did she look

　　本題考查主系表結構和倒裝句。應在 at 之前斷句。這就意味著 look與 at 并無直接關系，不是 look at the news，而是 look sad at the news，“因為聽到這個消息而傷心”。B．為正確答案。

　　8．______ different life today is from ______ was fifty years ago．

　　A．What a；what B．How；what 　　C．What；that D．What；how

　　此題斷句應在 different 和 life 之間，構成感嘆句：由 how 引導的對形容詞 different 進行感嘆強調。而 today 是時間狀語。本句意為：Life is different from what was fifty years ago．B為正確答案。

　　1．We grow all our grapes and vegetables here in the garden，______ cost us a lot of money，of course．

　　A．which B．ss C．that D．what

　　能力培養

　　高考中如何寫出好句子的能力培養

　　1．在書面表達中，要注意適當地使用一些詞組、習語來代替一些單詞，以增加文采，豐富語句的表現力。例如：

　　原文 The old man was hit by the car when he was crossing the street.

　　修正 The old man was knocked down by the car when he was crossing the street.

　　原文 A new railway is being built in my hometown.

　　修正 A new railway is under construction in my hometown.

　　原文 I like reading while my brother likes watching TV.

　　修正 I like reading while my brother enjoys watching TV.

　　英語習語、詞組十分豐富，在自己的書面表達中，能適當地使用這些短語，無疑是一個提高水平的十分行之有效的方法。

　　2．盡量避免過多地重復使用某一單詞，必要時應選擇使用其他恰當的同義詞或詞組來代替。例如：

　　原文 I like reading while my brother likes watching TV.

　　修正 I like reading while my brother enjoys watching TV.

　　3．要注意使用不同結構、不同長度的句子，盡量使句型多樣化，避免單詞。例如：

　　原文

　　There is a new classroom building on one side of the road. There used to be a playground on the other side before. But there is a library now. There are all kinds of books, newspapers and magazines in the library. There is a new playground in front of the school. There are a lot of trees in and around the school.

　　修正

　　On one side of the road there is a new classroom building. On the other side, where the playground used to be, now stands another new building-our library, in which you can find all kinds of books, newspapers and magazines. The playground is now in front of the school. We have also planted a lot of trees in and around the school.

　　4．多使用一些主從復合句來代替簡單句，能使書面表達行文更加流暢有力。例如：

　　原文 We had to stand there to catch the offender．

　　修正 All we could do was to stand there，trying to catch the offender．

　　原文 The meal was very nice．We all enjoyed it very much．

　　修正 The meal was so nice that we all enjoyed it very much．

　　5．改變句子開頭方式，不要一味地都是主語開頭，接著是謂語、賓語，最后再在句末加上一個狀語。我們可以適當地把一些成分(如狀語)提前位于句子的開頭，使整個句子讀起來有點跌宕起伏，增加書面表達的表現力。例如：

　　原文

　　The young man pointed to a policeman not far away and said，“He stopped us an hour ago and told us to catch another offender．”

　　修正

　　Pointing to apoliceman not far away，the young man explained，“He stopped us an hour ago and made us catch another offender．”

　　原文

　　I studied Chinese，maths，english，physics，chemistry and computer at school．

　　修正

　　The main subjects I studied at school included Chinese，maths，English， physics，chemistry and computer．

　　6．通過合句，將意義相關的幾個句子用一定的連接方式連接起來，或通過緊縮，去掉一些多余的成分，避免冗長累贅、松散無力，以增強句子的連貫性，達到更好的表達效果。例如：

　　原文

　　We had a short rest．Then we began to play happily．We sang and danced．Some told stories．some played chess．

　　修正

　　After a short rest，we had great fun singing and dancing，telling jokes and playing chess．

　　原文

　　My brother was riding the bike and I sat on the seat behind him．

　　修正

　　My brother was riding the bike with me sitting on the seat behind.

　　3 Writing

　　I live in Chongqing, a beautiful mountain city in Sichuan Province. There's a river, Jialing River, running by, but it is much polluted. Chongqing is an industrial city in which there are many factories. Many of them were built a long time ago. At one time, people in our hometown didn' t worry at all about pollution. The factories poured waste directly into the river, so that there was no fish in the river. Even now, it is not safe to bathe in it. Among the factories, the worst one was the paper factory, which was also the first one built in China. Now the city government is taking measures to stop the factories from polluting the fiver. I hope that our government will encourage them to put in new equipment and introduce new techniques to further reduce the pollution.
