2019-2020年初中英語 知識點總結(jié)課件 人教新目標版 1. 名詞 (1) 不規(guī)則名詞的單、復數(shù)形式要特別記憶: man—men, woman—women, child—children, foot—feet, tooth—teeth (2) 單數(shù)、復數(shù)同形的名詞: fish, sheep, deer, Chinese, Japanese (3) 常用復數(shù)形的名詞: trousers, shoes, glasses (4) 只有復數(shù)形的名詞: thanks, clothes (5) 單數(shù)形式但其意為復數(shù)的可數(shù)名詞: people, police (6) 有生命的名詞所有格形式: 單數(shù)名詞加’s, 復數(shù)名詞加s’, 不是以s結(jié)尾的復數(shù)名詞加’s, 如: children’s room (7) 無生命的名詞所有格用of結(jié)構(gòu)表達: 如: the capital of China (8) 表示并列名詞各自所有,在各名詞詞尾加’s: 如: Tom’s and Mary’s bikes (兩人各自的自行車) (9) 表示并列名詞共同所有,則在后一個名詞的詞尾加’s: 如: Tom and Mary’s mother (即Tom與Mary是兄妹) (10) 關于時間、距離、長度、重量、價格的所有格: 如: ten minutes’ walk, ten miles’ journey, a boat’s length, two pounds’ weight, ten dollars’ worth (11) 雙重所有格: a friend of my father’s 2. 形容詞與副詞 (1) 原級,比較級,最高級詞形變化: ① 〔單元音+單輔音〕的單音節(jié)詞 fat—fatter—fattest thin—thinner—thinnest hot—hotter—hottest big—bigger—biggest ② 以y結(jié)尾的雙音節(jié)詞 easy—easier—easiest heavy—heavier—heaviest pretty—prettier—prettiest 2、動詞不定式的用法之歸納匯總 動詞不定式(to do)是初中英語課的一個重點,也是中考要考查的一個項目。動詞不定式屬于非謂語動詞的一種形式,很多同學經(jīng)常把它和謂語動詞混在一起,掌握起來有困難。下面我們對動詞不定式的用法做簡單歸納,幫助同學們記憶: 一、動詞不定式在句子中不能充當謂語,沒有人稱和數(shù)的變化。 二、動詞不定式是由“to+動詞原形”構(gòu)成(有時可以不帶to)。動詞不定式的否定形式是“not+動詞不定式”(not不與助動詞連用)。 三、動詞不定式短語具有名詞、形容詞和副詞等的功能,可在句中用做多種句子成分。 1、主語:常置于句末,而用it代替其做形式主語。例: To go in for sports helps you stay fit.(book4,L28) It helps you stay fit to go in for sports. It is dangerous to swim in the deep sea on your own. 注:此句式中不定式邏輯上的主語可由for或of引出,邏輯主語由of引出時,表語的形容詞為kind,nice,good,polite,clever,foolish,right,wrong等表示評價的形容詞。 例:Its right of him to refuse the invitation.(him為邏輯主語) 2、表語:Our duty is to protect the enviroment. 3、動詞賓語:此種情況可按固定搭配或句式去記。 例:would you like to see my photos? Kevin planned to visit his uncle.(book4,L11) 和plan用法一樣的詞還有:start,want,agree,hope,begin,decide等。 I found it very difficult to get a job.(it為形式賓語) 4、賓語補足語: (1)在多數(shù)復合賓語及物動詞后要帶to。 例:I asked a friend to read it to me.(book4,L2) (2)在表示感覺、致使等意義的動詞(see,watch,hear,feel,notice,observe,make,let,have,help等)后不帶to。 例:They heard him sing a pop song in the meeting room. 5、定語:動詞不定式做定語放在所修飾的名詞的后面。 例:Vinny is the first disabled person to sail around the world.(book4,L1) 6、形容詞補足語:在表示心理、感情、評價等的形容詞后,對其進行補充說明。 例:Weareverygladtomeetyouagain. 7、狀語:表示目的、原因、程度等。 例:They brought in photos of their families for me to look at.(book4,L2) 8、“疑問詞+不定式”用法:不定式前可帶what,who,which,where,when,how等疑問詞,這種不定式短語在句中多用做賓語。 例:He didnt tell me where to go. 9、在初中階段還涉及到“不定式被動語態(tài)一般式(tobe+過去分詞)”。 例:There are twenty more trees to be planted. ※英語中省略冠詞的情況一覽 (1) 稱呼語之前不加冠詞。 Waiter, bring my bill, please. (2) 家庭稱謂如父母兄弟前不加冠詞,甚至傭人也都不需加冠詞。 Father is out, but Mother is at home. Cook has made mince-pies for Christmas. (3) 三餐名稱前不加冠詞。 e to dinner (breakfast, lunch) with me. (4) 運動、游戲、顏色、感官的名詞前不加冠詞。 He likes basketball. White is a beautiful color. Do you play bridge? Sight is one of the five senses. (5) 表官職、身份或親屬關系的名詞當補語或作同位語時不加冠詞。 He was elected president. George Ⅵ, King of England. (6) School; church; hospital等字,指原有的用途時不加冠詞,若指建筑物本身或場所時,則要加冠詞。 School begins at eight. (school作抽象名詞用) The school stands on the hill. (school指建筑物) (7) 兩個相對的名詞并用時不加冠詞。 Arm in arm; day by day; man to man; young and old 英文中各種數(shù)字表達的讀法 (1) 年號的讀法: 1979←→nineteen seventy-nine / nineteen hundred (and) seventy-nine; (2) 電話號碼;貨幣的讀法: 1023←→one o two three; 1227←→one double two (或 two two) seven; (3) 小數(shù)點的讀法: 13.91←→thirteen decimal (point) nine one; 0.23 = nought demical two three; (4) 算術式的讀法: 2+3=5 Two plus three is (或equals, is equal to) five. 5-3=2 Five minus three is equal to two. 32=6 Three times two is six. 93=3 Nine divided by three makes three. (5)貨幣的讀法 $4.25←→four dollars (and) twenty-five (cents); 名詞的相關形式與表達 ※在中考單項選擇試題中,除了時態(tài),名詞的考查頻率也較高。一般考查以下幾點: 一、 可數(shù)名詞與不可數(shù)名詞 在可數(shù)名詞與不可數(shù)名詞上一般出現(xiàn)這樣幾類,(1)分辨是哪一類名詞,并根據(jù)結(jié)論做選擇。(2)可數(shù)名詞復數(shù)的不規(guī)則變化。(3)不可數(shù)名詞的量化表達。所以,考生首先要能夠明確哪些是可數(shù)名詞,哪些是不可數(shù)名詞。其次,還要知道可數(shù)名詞的復數(shù)的變化規(guī)則??蓴?shù)名詞的變化規(guī)則一般是在單詞后面加-s 或-es,如: 1. desk---desks bed---beds piano---pianos hat---hats bag---bags photo---photos 2. bus---buses box---boxes watch---watches brush---brushes 3. t omato---tomatoes potato---potatoes hero---heroes Negro---Negroes 4. leaf---leaves knife---knives 5. baby---babies family---families 另外,還要記住一些特殊的名詞的變化形式,如: Chinese---Chinese Japanese---Japanese Englishman---Englishmen Frenchman---Frenchmen Russian---Russians American---Americans German --- Germans child---children foot---feet man---men woman---women tooth---teeth goose --- geese deer---deer sheep---sheep 還要掌握不可數(shù)名詞的量化表達有: a piece of、a bag of、a bottle of、a cup of、a glass of 。 另外,大家應注意:單數(shù)集合名詞作主語時謂語動詞“數(shù)的”變化:單數(shù)集合名詞如class, police, family, school, group, team等。盡管形式上是單數(shù),意義上都是復數(shù),因此,一般要與復數(shù)謂語動詞連用,例如: Class Five have a foreign friend. 五班有一位外國朋友。(這里的五班指五班的同學的。) His family are good to me. 他的家人對我很好。(很顯然,這里的family指家庭成員。) 當上述集合名詞著重指“整體”時, 意義上則是單數(shù),因此,要與單數(shù)謂語動詞連用。例如: Our school team often plays well in our city. 我們的校隊經(jīng)常在我們市踢得很好。(這里的team 指整個隊,但意義上仍為單數(shù),故謂語動詞用plays. ※ 名詞所有格 名詞所有格有兩種形式:一是加s,一種是用of來表示。一般情況下,指某人的某物用s表示,而指某物的什么用of 短語來表示。另外,要注意凡是以s結(jié)尾的名詞或規(guī)則名詞的復數(shù),不能直接加s,而應該加- 即可。例如,boys clothes girls dresses。 不過,注意例外情況,例如, the bosss handwriting,其中the bosss 的-s不可省略。因為在英語中,如果以-s 或-ss 結(jié)尾的名詞不是復數(shù)復數(shù)形式,那么其名詞所有格仍加-s。那么你會說“瓊斯的小汽車”嗎?對,Joness car。 下面我們來做一部分習題。 1.
