特殊變化有以下:
單數(shù)復(fù)數(shù)一個(gè)樣, sheep--sheep fish- fish  goldfish - goldfish    Chinese-Chinese   Japanese -Japanese
2.遇到oo 變ee :  foot-feet   goose- geese   tooth - teeth
3.有些變化就是大:mouse – mice  child - children  man-men  woman-women
4 .以s, x, sh, ch 結(jié)尾 , +es   (bus-buses, box-boxes,  brush-brushes,

5、以0 結(jié)尾(有生命的o)+es        (tomato-tomatoes)(番茄)       例外:kangaroo- kangaroos
6、以輔音字母+y結(jié)尾,改y為i+es  ( lady-ladies,  baby-babies  study-studies)
7.以f 或fe結(jié)尾,改f或fe為v+es       (knife- knives   shelf-shelves)

三、have與has 的區(qū)別:
have, has 都是“有”,
它們的用法有講究, 表示“某人有某物”,have, has請(qǐng)記住。 he, she, it “有”用has,    I, we , they , you 都用 have。 主人單數(shù)用 has , 主人復(fù)數(shù)用 have。
have 就是能力強(qiáng),疑問(wèn) ( ?)否定 (don’t / do not)都用它。

四、have ,has 與there is , there are 的區(qū)別

一般來(lái)講,元音字母(即a, e , i, o , u )開頭的單詞用an
如: an apple   an ear   an American girl    an Australian stamp   an old man

七. There be 句型  (即 there is / there are )
意思: 表示某地方有某人或某物 原則:就近原則 (There be 句型中的be 動(dòng)詞用is 還是用are 由最靠近它的第一個(gè)名詞是單數(shù)還是復(fù)數(shù)決定。)
如: There is a book and some pens on the desk.      There are some pens and a book on the desk.

八.不可數(shù)名詞:
juice   chalk   tissue  (不可數(shù)名詞沒(méi)有復(fù)數(shù)形式)

the headmaster’s office   校長(zhǎng)的辦公室  the children’s  toys      兒孩子們的玩具
the teachers’  room    教師辦公室  (當(dāng)名詞的復(fù)數(shù)形式是以“s”結(jié)尾時(shí),直接加 ’)

十. be 動(dòng)詞 :
is  are  am ( 表示“是” )
I 用am  , you 用are , is 連著he,she ,it 。單數(shù)名詞用is ,復(fù)數(shù)名詞全用are 。  如: I am ….   You are… .   We are… .   They are…. .  He is…..  She is…..    It is….       The girl is ….   The boys are….    Ben is….    Janet and Ben are…
