3、 like before.its yesterday once more批注：讓學生邊聽音樂邊思考（可以看著歌詞聽），我們會發(fā)現(xiàn)歌詞中涉及到了各類代詞，讓學生自己去總結(jié)歸納，老師做補充即可，既可以激發(fā)學生的興趣，又可以發(fā)揮學生的主觀能動性。一、專題精講 知識點1：代詞的含義和分類1. 代詞的含義：代詞是為了避免重復，用來代替名詞或者名詞短語的詞。2. 代詞的分類根據(jù)功能不同，代詞可以分為八大類。 分類含義形式 人稱代詞表示我（們）、你（們）、他（們）、她（們）、它（們）的詞主格：I, we, you(你),you(你們), he, she, it, they賓格：me, us, you(你),

4、you(你們),him, her, it, them 物主代詞表示物體所屬關(guān)系的代詞形容詞性物主代詞：my, our, your(你的),your(你們的), his, her, its, their名詞性物主代詞：mine, ours, yours(你的東西)，yours(你們的東西), his, hers, its, theirs反身代詞用來表示 “某人自己”的詞myself, ourselves, yourself, yourselves, himself, herself, itself, themselves指示代詞用來指代或標識人或事物近指：this（可用于電話用語）, these

5、遠指：that（可用于電話用語）,those疑問代詞用來表達疑問或構(gòu)成疑問句的代詞who, whom, whose, what, which 不定代詞表示籠統(tǒng)指代，不能確定指代具體哪些人或物much,little,some,any, none,neither,few,other,everything,someone,something,somebody等關(guān)系代詞連接定語從句的代詞that, which,who, whose, as, whom相互代詞(考查較少)表示相互關(guān)系one another, each other批注：中考指導書上代詞部分要求掌握的知識點包括六個：人稱代詞、物主代詞、反身

6、代詞、指示代詞、不定代詞和疑問代詞。所以教師要提醒學生一定要掌握牢固。另外需要注意的是這里的關(guān)系代詞是在定語從句考點中重點強調(diào)的，所以不在代詞部分具體闡述。最后，本份講義專題部分主要是針對人稱代詞、物主代詞、反身代詞和指示代詞的考點展開的，后面的幾種代詞將放在介詞（二）具體闡述，這點是需要向?qū)W生說明的。知識點2：人稱代詞人稱代詞主格和賓格的區(qū)分要點：人稱代詞主格作主語，放在句首；人稱代詞賓格作賓語，放在動詞和介詞之后。做題時需要注意代詞的位置，根據(jù)位置選擇。如：I love my country.My mother is waiting for him outside.I dont know

7、her. 批注：這里需要提醒學生，考試中經(jīng)常會出現(xiàn)主格變賓格的題目，也是?？键c，基礎差的學生直接讓其辨清哪些是主格，哪些是賓格即可。例題(一)：用所給詞的正確形式填空1. There are lots of rivers in China, and the longest of (they) is the Changjiang River.答案：them解析：根據(jù)句意：中國有很多河流，他們中最長的是長江。這里of是介詞，表示“.的”，介詞后接賓語，用賓格，所以答案是將括號內(nèi)的主格they變成賓格的them。 2. Dad, Mum asked you and _ (I) to do the c

8、leaning at home today.答案：me解析：該題考查人稱代詞的賓格用法。題中ask是動詞，動詞后接賓語，用賓格。所以答案是將括號中的主格I 變成賓格me。例題(二)：單項選擇1. Han Han is very popular among the teenagers. We all like_.A. him B.he C. she D. himself解析：本題考查人稱代詞中的賓格。這里like是動詞，動詞后接賓語，用賓格，答案選A。2. -Look ,thats Mike, your classmate. -Yes. Lets go and say hello to_. A.

9、himB.heC.herD.them解析：本題考查人稱代詞賓格的用法。這里say hello to sb. 是固定詞組，表示向某人問好，to是介詞，后面跟賓語，使用賓格. 所以排除B。又因為Mike是男孩名而且是單數(shù)，所以答案選A。3. We have noticed the problems，and _ will be discussed at the meeting. A. you B. it C. they D. us解析：考查人稱代詞的用法。代替上文的the problems，是復數(shù)，所以是they，因此選擇答案C。知識點3：物主代詞1. 形容詞性物主代詞和名詞性物主代詞的區(qū)分要點：形

10、容詞性物主代詞具有形容詞的特點，不能在句中單獨使用，后面要跟名詞；名詞性物主代詞具有名詞的特點，可以在句中單獨使用，后面不接名詞。如：His parents are both office workers.This is my dictionary. Where is yours?My idea is quite different hers.批注：做題時，需要提醒學生觀察代詞后是否有名詞，這是做題的關(guān)鍵。例題（一）：用所給詞的正確形式填空1. Our house is a little larger than _ (they) and it has more furniture in it.

11、答案：theirs.解析：根據(jù)句意：我們的房子比他們的大一點，家具比較多。這里是我們的房子和他們的房子比，所以是所屬物品之間的比較，那首先要選用物主代詞，其次這里后面沒有名詞，所以要選用名詞性物主代詞theirs. 2. May I introduce Mike, a good friend of (I) to you?答案：mine批注：名詞性物主代詞可用在of后面與of 共同作定語，相當于“of + 名詞所有格”，表示帶有部分概念或一定的感情色彩。如：He is a friend of mine. 例題（二）：單項選擇1. Lost in Thailand is a very succes

12、sful comedy. Its favorite movie. I like it very much. A. hisB. mineC. herD. my解析：考查形容詞性物主代詞的用法。根據(jù)句意，排除A和C。my形容詞性物主代詞，常放在名詞前表所屬。又空后有名詞movie，故選D項。2. Excuse me, is this _ new camera? Yes, its _. A. your; my B. your;mine C. yours;my D. yours;mine解析：本題考查的是形容詞性物主代詞和名詞性物主代詞的辨析。第一空后有名詞，選用形容詞性物主代詞；后一空后沒有名詞，選

13、用名詞性物主代詞。因此答案選B。3. This is not my Walkman. Its _. Mine is over there.A. our B. hers C. your D. my解析：考查物主代詞的用法。選項中出現(xiàn)的都是物主代詞，根據(jù)橫線后沒有名詞，所以應該使用名詞性物主代詞。所以答案選B。2. 人稱代詞和物主代詞的區(qū)分要點：人稱代詞指代的是人或物，而物主代詞指的是人與人、人與物之間的所屬關(guān)系。批注：做題時可以進行簡單的翻譯，一般翻譯中帶有“.的”就選用物主代詞。例題（一）：單項選擇1. If you want people to treat you nicely, you h

14、ave to treat nicely, too.來源:學?？?。網(wǎng)Z。X。X。KA. their B. they C. them D. themselves解析：根據(jù)句意：如果你想別人友好地對待你的話，你也不得不友好地對待他們。橫線處應該填“他們”，用人稱代詞，所以排除A和D。其次treat是動詞，動詞后接賓語，用賓格，所以排除B, 答案選C。2. After Mo Yan won the Nobel Prize, more people began to read _ books.A. he B. him C. his D. himself解析：根據(jù)句意：莫言得了諾貝爾獎之后，更多人開始讀他

15、的書。書和他之間是所屬關(guān)系。直接就可以根據(jù)句意排除A、B、D。答案選C。3. Have you got an iPhone 5? No, many young people began to say “No” to it because of _ follow-up service. By the way, I am a supporter of Chinese products. A. its B. its C. it D. itself 解析：根據(jù)句意：-你有iphone5嗎？-我沒有。更多人開始對這個問題給予否定回答因為它的售后服務。順便說一下，我支持國產(chǎn)。its 一般是it is或者i

16、t has 的縮寫；it是它；itself是它自己。根據(jù)句意，這里的它和售后服務之間是所屬關(guān)系。所以選用物主代詞。答案選B。4. Is this new book, Shirley? No, it isnt. Maybe its . A. your; hisB. your; himC. yours; hisD. yours; him解析：查物主代詞的用法。形容詞性物主代詞后須接名詞，名詞性物主代詞后不需接名詞。第一道橫線的后面有名詞book, 所以用形容詞性物主代詞；第二道橫線的后面沒有名詞，所以用名詞性物主代詞。故選A。5. This morning Diana invited _to _b

17、irthday party.A. I; her B. I; hers C. me; her D. me; hers解析：考查人稱代詞和物主代詞辨析。句意：今天早上Diana邀請我參加她的生日晚會。本句中 invited 是及物動詞，其后要接賓語，第一個空要用賓格人稱代詞，排除A、B；第二空后有名詞birthday party，需用形容詞性的物主代詞修飾，排除D。選C。知識點4：反身代詞的人稱、性、數(shù)的選擇批注：教師需要提醒學生的是反身代詞的考查難度不大，但是是中考的?？键c。反身代詞的?？键c一是人稱和數(shù)的選擇，所以要注重句子的翻譯，特別要注意人稱的對應和反身代詞單復數(shù)的選擇。反身代詞的?？键c二是

18、一些固定搭配的選用。含有反身代詞的常用結(jié)構(gòu)：help oneself (to) 自便，enjoy oneself 玩的開心，teach oneself自學， say to oneself自言自語，lose oneself in 沉湎于, devote oneself to 奉獻，leave sb. by oneself 將某人獨自留下，keep a secret to oneself 保密，hurt oneself受傷，by oneself獨自等。如：The little boy is too young to look after himself.The children made mode

19、l planes by themselves.例題（一）：單項選擇1. Hi, guys. How was your party yesterday? Wonderful! We had a big meal and enjoyed .A. themselvesB. myselfC. yourselvesD. ourselves解析：考查反身代詞的用法。themselves“他們自己”，myself“我自己”，yourselves“你們自己”，ourselves“我們自己”。據(jù)句意“我們吃了頓大餐，玩得很開心”，所以選擇答案D。2. Peng Liyuan, the new first lad

20、y, has devoted _ to charity activities over the years. A. sheB. herC. hersD. herself解析：考查反身代詞的用法。這里devote oneself to sth.是固定詞組，表示奉獻于.,所以答案選D。3. Is this model plane yours, Susan? Yes, its mine.

A. you B. yoursC. yourself D. yourselves解析：本題考查反身代詞的固定搭配help oneself to，表示自便。先排除A、B。另外根據(jù)后面的my boy,說明是單數(shù)，因此答案選C。例題（二）：用所給詞的適當形式填空1. Come and enjoy _(yo

22、u), dear! Its my honor to invite all of you here.2. “Youre old enough, boy. Youd better do it (you).” My father said to me.3. It is too dangerous for the young children to play near the river by_ (they)4. My daughter is old enough to look after (she). She can stay at home alone.5. Sometimes teenager

23、s should be allowed to make decisions by (自己).答案：1. yourselves 這是一道考查反身代詞性和數(shù)一致的典型例題。由后句的“all of you”可以判斷前面的反身代詞 需要用復數(shù)。 2. yourself 3. themselves 這里使用到了固定詞組by oneself，表示獨自。 4. herself 5. themselves批注：1、2兩題說明you這個詞比較特殊，提醒學生遇到變反身代詞時一定要考慮用單數(shù)還是復數(shù)。 題目3中出現(xiàn)了固定詞組by oneself表示獨自，同義詞組有alone,on ones own. 在教學過程中，

24、教師要提醒學生注意句型轉(zhuǎn)換中容易出現(xiàn)這個知識點。如：他獨自完成了家庭作業(yè)?？梢苑g成He finished his homework by himself./ He finished his homework alone. / He finished his homework on his own. 2、 專題過關(guān)檢測題（一）: 單項選擇1.

Both D. None解析：本題考查不定代詞的詞義辨析。根據(jù)后面的I dont care, 說明都可以。所以選擇A,表示兩者中任一個都可以。neit

26、her表示兩者都不要；both是兩者都要，但是題目中空格后謂語動詞是單數(shù)的is，所以排除C；none表示一個都沒有，不符合句意。故選A。4. -Can I have some more ice cream, Mum? -Sorry. There is _left in the fridge. A.none B.nothing C. something D.anything解析：本題考查復合不定代詞的辨析。none 表示上文提到事物的數(shù)量一個都沒有； nothing沒有東西，表示什么都沒有; something表示某些東西；anything 用在肯定句中表示任何事物。根據(jù)句意：-媽媽，我能再吃點

27、冰激凌嗎？-對不起，冰箱里沒剩下的了。這里強調(diào)的是上文提到事物的數(shù)量一個都沒有，故答案選A。5. -I dont know _ she is. -She is our new English teacher. A.whatB.whoC.whichD.when解析：本題考查疑問代詞的用法辨析。根據(jù)答句“她是我們的新英語老師”可知，前句應該是對人姓名或身份的提問，因此答案選B。6. The teachers and the students _ came to visit Nanjing Museum are from England. A. thatB. whichC. whatD. whose

28、解析：本題考查關(guān)系代詞的用法。這里先行詞the teachers and the students在后面的定語從句中充當主語。所以先排除C和D。其次，which只能指物，所以答案選A。7. Im afraid Ill fail in this exam. Come on, Andy. You must believe in _.

It is a good habit of to read a few lines before going to bed. A. I B. me C. my D. mine解析：考查名詞性物主代詞的用法。根據(jù)句意“睡覺前讀幾行書是我們的（習慣中）一個好習慣”可知，此處表示泛指我們中的一個，故用名詞詞性物

Amy is lying on the grass doing nothing. A. me B.I C.him D.her 解析：句意：-Sally, 你能去幫你爸爸洗車嗎？-為什么是我呢?我現(xiàn)在很忙，Amy正躺在草地上什么都沒做。根據(jù)后文Im busy now，先排除C和D。Why

35、案：Its; ourselves; Her; ourselves; Ours; him三、學法提煉1、專題特點: 本專題只涉及到代詞中人稱代詞、物主代詞、反身代詞的用法。對人稱代詞、物主代詞和反身代詞的考查在于理解并掌握人稱代詞、物主代詞的用法，區(qū)別運用人稱代詞的主格及賓格；掌握名詞性物主代詞相當于“形容詞性物主代詞+名詞”的用法。2、 解題方法：（1） 人稱代詞和物主代詞的運用技巧：解題步驟：1. 根據(jù)句意選擇用人稱代詞還是物主代詞；2.如果用人稱代詞考慮用主格還是賓格；如果用物主代詞考慮用形容詞性還是名詞性。 A. 首先運用口訣解題。主格作主語，賓格作賓語；空在動詞前，主格填；空在動詞后，

36、賓格填沒錯；空后有人物，形容詞性填入；空后無人物，名詞性填入。 B. 然后翻譯句子，檢查答案是否正確。 C. 注意“動賓結(jié)構(gòu)”及“介賓結(jié)構(gòu)”（2） 反身代詞的用法，記住以下短文。中：如果我獨自居住，我會自己洗澡，自己穿衣，自己玩得開心，放松自己，給自己買點好吃的，但是如果我隨便吃東西，我會傷到我自己，我不得不自學醫(yī)學知識，照顧好自己。英：If I live by myself, I can wash myself, dress myself, enjoy myself, relax myself and buy myself some delicious food. But if I help

37、 myself to some food, I will hurt myself. I have to teach myself medical knowledge and look after myself. 3、 注意事項：（1） 部分人稱代詞和物主代詞形式上會用相同，需要注意區(qū)分。如：his可以是形容詞性物主代詞也可以是名詞性物主代詞；her既可以是人稱代詞的賓格也可以是形容詞性物主代詞。（2） 進行反身代詞的選擇時，一定要注意人稱的一致性和數(shù)的變化。因此，做題時一定要注重句子人稱的單復數(shù)和變化。1、 專題精講 知識點1：it, that, one的選擇批注：該考點在近幾年的中考中出現(xiàn)較

38、多，也是一個較難的考點，教師需要提醒學生注意。區(qū)分要點： it指與前面已經(jīng)提到的事物為同一物。簡稱“同類又同物”。如：The book is mine. Its very interesting. one 指與前面提到事物為同類事物。簡稱“同類不同物”，屬于泛指。復數(shù)形式是ones. 如：-Who has a pen?-I have one. that常用于比較結(jié)構(gòu)中，指與前面提到事物為同類事物。簡稱“同類不同物”，但屬于特指。復數(shù)形式是those. 如：The weather in Beijing is colder than that in Guangzhou in winter. 例1：

39、The actors in this film played better than _ in that film.A. those B. that C. it D. this解析：根據(jù)句意：這部電影里的演員比那部電影里的演員表演的要好。首先，所填部分是代替那部電影里的演員，所以和這部電影里的演員屬于同類不同物，而且是復數(shù)，所以排除B、C、D。因此答案是A。 例2： -Have you got any books on English grammar? I want to borrow_. -Yes, here you are. But you must return it by Friday

40、. A. one B. it C. some D. that解析。one泛指一個，it常常指代前文提到過的一個，some指代一些且泛指，that特指那個，因答句中有it，說明肯定是單數(shù)；又因為句意提示是泛指的一本關(guān)于英語語法的書，所以答案選A。例3： I bought Tiny Times, a book written by Guo Jingming. Would you like to read _? No, thanks. I have already bought _.A one; it Bit; one Cone; one Dit; it 解析：根據(jù)句意：-我買了小時代，是郭敬明寫的

41、一本書。你想要讀嗎？-不，謝謝。我已經(jīng)買了一本了。第一空就是指的“我買的那本郭敬明的書”，所以是同類又同物，選用代詞it ;第二空指的是“和我買的書一樣的一本書”，所以是同類不同物，又屬于泛指選用代詞one. 綜合來看，答案選B。例4：-Mum, Mary bought a parrot yesterday. Could you please buy _ for me? - Sure. But you must take good care of_. A. one;itB. this;oneC. it;oneD. one;one解析：根據(jù)句意：-媽媽，瑪麗昨天買了一只鸚鵡，你能給我買一支嗎?-

42、當然可以，但是你必須好好照顧它。one指代同類事物之中任一個，此處指a parrot; it指代上文提到的同一事物，此處指媽媽買回來的那只鸚鵡。因此答案選A。例5： I forget to bring a pen. Would you lend me _? A. one B. that C. it Dthis解析：根據(jù)句意：我忘了帶筆，你能借我一只嗎？這里要借的筆和前面的筆屬于“同類不同物”，排除C和D。又因為這里是泛指，所以答案選A。知識點2: 代詞it的用法批注：該知識點是初中階段很重要的一個知識點，而且用法比較多，教師需要提醒學生特別注意。代詞it的用法較多，主要的有： 一、單獨使用1.

43、 指代前面提到過的事物。如：This is not my book. Its Jims.2. 指代嬰兒或不明身份的人。如：Someone is knocking at the door, please go and see who it is.3. 指時間、季節(jié)、天氣、時間、星期或距離。如：It is ten oclock.It is sunny today.How far is it from your school to your home?2、 用在某些固定句型中（教師需要重點通過例題教授）1. 用作形式主語，常用于下列句型中： It is +形容詞/名詞+ for/of sb. to

44、do sth. 表示對某人來說做某事是./ 某人做某事是.的。如：It is important for us to work hard.It is nice of you to help me so much.It is an honor for me to get the prize. 批注：當形容詞描述的是行為者的性格品質(zhì)，如nice, kind, good, wrong, clever, foolish, silly, careless, generous, selfish, Polite等，則用句型It is +形容詞+of sb to do sth; 當形容詞描述的是整個不定式的情

45、況或者怎樣，如important, necessary, impossible, possible, interesting, hard, difficult, easy等，則用句型It is +形容詞+for sb to do sth. It is +形容詞+that從句。如：It is necessary that you should be present at the meeting. It is time to do sth./It is time for sth./ It is time +that從句，表示到做.的時間了。如：It is time to get up.It is

46、time for lunch.It is time that we go home.It seems that ., 表示看起來好像.如：It seems that he is very happy. It is ones turn to do sth.表示輪到某人做某事。如：It is your turn to sing. It takes/took sb. +時間+to do sth.表示花費某人多長時間做某事。如：It took me two months to write the article. 2. 用作形式賓語句型：sb. finds/thinks /makes it+形容詞+t

47、o do sth. 表示某人發(fā)現(xiàn)/認為做某事是.的。如：I find it interesting to make model planes. I think it necessary to learn English well. He made it a success. 3. 用于某些被動句句型中It is believed/reported/said/considered +that從句.表示大家認為./據(jù)報道./據(jù)說./人們認為. 如：It is believed that he will come to the party on time. It is reported that t

48、he president will come to visit our city next month. It is said that the story he told us yesterday is true.It is considered that he must keep a secret to himself. 例1：The doctor advised Elsa strongly that she should take a good rest, but _ didnt help.A. she B. it C.which D.he 解析：根據(jù)句意：醫(yī)生強烈建議Elsa好好休息，

49、但是毫無效果。這里毫無效果就是指的前面的醫(yī)生的建議，所以是考查it指代前面說過事物的用法，答案選B。例2：-Who is singing in the next room？ -_ must be Marie.A. It B. She C.This D. There解析：根據(jù)句意：-誰在隔壁唱歌？-肯定是Marie. 這里是考查it用于表示未知的人或物。所以答案選A。例3：All of us find_ necessary to take exercise every day.A. this B. that C.it D.them解析：根據(jù)句意：我們所有人都覺得每天鍛煉很有必要。這里考查的是fi

50、nd it+形容詞+to do sth. 的句型。 此處it做find 的形式賓語，指代 to take exercise every day. 所以答案選C。例4：We think _ necessary to protect the earth. A.it B.this C. that D.what解析：此處考查的是形式賓語it的用法。Sb. find it +形容詞+to do sth. 意思是“某人發(fā)現(xiàn)做某事是.”,故答案選A。例5：Class 2 will go for a picnic. They made _6 oclock to meet at the foot of Mt.T
