1、 人稱代詞并列用法的排列順序
1)單數人稱代詞并列作主語時,其順序為: 第二人稱->第三人稱->第一人稱 即:youandI;he/she/itandI;you,he/she/itandI
2)復數人稱代詞作主語時,其順序為: 第一人稱->第二人稱->第三人稱 即:weandyou;youandthey;we,youandthey
2、 人稱代詞用法: 謂語之前主格填,動/介之后賓格跟,形容詞性物主代詞后跟名詞,名詞性物主代詞可單獨使用。人稱代詞并列現,注意順序禮貌見, 二一、三一、二三一,第一人稱最謙虛,
3、 be 的用法口訣:我用am,你用are,is連著他,她,它; 單數名詞用is,復數名詞全用are。
變疑問,往前提,句末問號莫丟棄。 變否定,更容易,be后not莫忘記。 疑問否定任你變,句首大寫莫遲疑。
4、第三人稱單數用does,其它人稱用do。第一人稱單數和第三人稱單數用 was, 其余人稱用 were ;
she ,he ,it "有"用has,其它人稱"有"用have;I用shall,其它人稱用 will。
名詞復數
1、規(guī)則變化:
1) 直接加 –s: 清輔音后讀/s/ 濁輔音和元音后讀 /z/
2) 以s, x, ch,sh,結尾加 –es, 讀 /iz/
3) 不是以a、e、i、o、u+y結尾的,變y 為i再加es, 讀 /z/
4) 以元音字母a、e、i、o、u+y 結尾的,或以y結尾的專有名詞,直接加s。
5) 以o結尾的名詞,變復數時:a. 加s,如: photo---photos piano---pianos   radio---radios zoo---zoos;
b. 加es,如:potato—potatoe  tomato--tomatoes c. 上述a和b兩種方法均可,如zero---zeros / zeroes。
6) 以f或fe 結尾的名詞變復數時:  a. 加s: belief---beliefs roof---roofs   safe---safes gulf---gulfs;
b. 去f,fe 加ves:half—halves    knife--knives    leaf—leaves    wolf—wolves
wife—wives     life—lives      thief--thieves;
c. 上述a和b兩種方法均可,如handkerchief: handkerchiefs / handkerchieves。
2、不規(guī)則變化
1) child---children foot---feet tooth---teeth  mouse---mice  man---men woman---women
注意:由一個詞加 man 或 woman構成的合成詞,其復數形式也是 -men 和-women,
2) 單復同形:deer,sheep,fish,Chinese,Japanese ,li,jin,yuan,two li,three mu,four jin但除人民幣的元、角、分外,美元、英鎊、法郎等都有復數形式。
3)集體名詞,以單數形式出現,但實為復數。如:people police cattle 等本身就是復數,不能說 a people,a police,a cattle,但可以說a person,a policeman,a head of cattle.
4) 以s結尾,仍為單數的名詞,如:a. maths,politics,physics等學科名詞,一般是不可數名詞,為單數。b. news 為不可數名詞。c. the United States,the United Nations 應視為單數。
d. 以復數形式出現的書名,劇名,報紙,雜志名,也可視為單數。
5) 表示由兩部分構成的東西,如:glasses (眼鏡) trousers, clothes等,若表達具體數目,要借助數量詞 pair(對,雙); suit(套); a pair of glasses; two pairs of trousers等。
6)復數形式有時可表示特別意思,如:goods貨物,waters水域,fishes(各種)魚。
變一般疑問句、否定句的方法
變一般疑問句方法:
1、如句子中有am, is, are, was, were、can, would,則提前在句子最前面,注意把am變?yōu)閍re,把was變?yōu)閣ere把I變?yōu)閅ou;把my變?yōu)?your 把our 變?yōu)閥our
2、如沒有am, is, are, was, were、can, would,判斷①動詞是過去式,動詞改為原形,句前加Did,其余照抄;
②動詞是第三人稱單數,動詞改為原形句前加Does,其余照抄;
③動詞是原形,則句前加Do,其余照抄。
變否定句方法:
1、句中有am, is, are, was, were,can, would,再其后加not,并縮寫,其余照抄
2、如沒有am, is, are, was, were或can, would,判斷①動詞是過去式,動詞前加didn’t動詞改為原形,其余照抄;
②動詞是第三人稱單數,動詞前加doesn’t,動詞改為原形,其余照抄;
③動詞是原形,動詞前加加don’t,其余照抄。
一般疑問句和否定句的變化口訣: 一般問句并不難,謂語調到主語前。大寫小寫有變化,句末要把問號加。
第一人稱常變二。否定句就更簡單,中間加上一not,謂語動詞提到前。
一、改為一般疑問句:
1、  先找句子中如有am, is, are, was, were、can, would,則提前在句子最前面,注意:(1)把am變?yōu)閍re,把I變?yōu)閅ou;(2)如主語是I時,把was變?yōu)閣ere提前,把I變?yōu)閅ou。
2、  如沒有am, is, are, was, were、can, would,則判斷是否為過去式,是則動詞改為原形,句前加Did,其余照抄;不是則判斷是否為第三人稱單數,是則動詞改為原形,句前加Does,其余照抄;還不是,則句前加Do,其余照抄。
二、改為否定句:
1、先找am, is, are, was, were或can, would,再其后加not,其余照抄
2、如沒有am, is, are, was, were或can, would,則判斷是否為過去式,是則動詞改為原形,主語后加didn’t,其余照抄;不是則判斷是否為第三人稱單數,是則動詞改為原形,主語后加doesn’t,其余照抄;還不是,則主語后加don’t,其余照抄。
何為是第三人稱單數
一、人稱代詞he, she, it是第三人稱單數。
二、單個人名、地名或稱呼作主語時是第三人稱單數。
三、單數可數名詞或"this / that / the+單數可數名詞"作主語時,是第三人稱單數。
四、不定代詞someone, somebody, nobody, everything, something等及指示代詞this, that作主語時,是第三人稱單數。
五、不可數名詞作主語時為第三人稱單數。
六、當數字或字母作主語時,看作第三人稱單數。
