特殊变化有以下：单数复数一个样， sheep--sheep fish- fish #160;goldfish - goldfish #160; #160;Chinese-Chinese #160; Japanese -Japanese2.遇到oo 变ee : #160;foot-feet #160; goose- geese #160; tooth - teeth3.有些变化就是大：mouse – mice #160;child - children #160;man-men #160;woman-women4 .以s, _, sh, ch 结尾 ， ＋es #160; (bus-buses, bo_-bo_es, #160;brush-brushes,watch-watches)5、以0 结尾（有生命的o）+es #160; #160; #160; #160;(tomato-tomatoes)(番茄) #160; #160; #160; 例外：kangaroo- kangaroos6、以辅音字母＋y结尾，改y为i＋es #160;( lady-ladies, #160;baby-babies #160;study-studies)7.以f 或fe结尾，改f或fe为v＋es #160; #160; #160; (knife- knives #160; shelf-shelves)三、have与has 的区别：have, has 都是“有”,它们的用法有讲究, 表示“某人有某物”，have, has请记住。

he, she, it “有”用has， #160; #160;I, we , they , you 都用 have 主人单数用 has , 主人复数用 havehave 就是能力强，疑问 （ ？）否定 （don’t / do not）都用它四、have ，has 与there is , there are 的区别表示某人或某动物 有 #160;： has / have #160; #160;(I have a dog.#160; The dog has a short tail.) 表示某地方 有： there is / are #160; #160; #160; (There is a book in the bag.)五、Some与any 的区别：some用于肯定句中，any用于否定句和疑问句中如：I have some books.#160;I don’t have any books.#160;Do you have any books ?六．a #160;与an 的区别一般来讲，元音字母（即a, e , i, o , u ）开头的单词用an如： an apple #160; an ear #160; an American girl #160; #160;an Australian st #160; an old man七． There be 句型 #160;（即 there is / there are ）意思： 表示某地方有某人或某物 原则：就近原则 （There be 句型中的be 动词用is 还是用are 由最靠近它的第一个名词是单数还是复数决定。

如： There is a book and some pens on the desk.#160; #160; #160;There are some pens and a book on the desk.八.不可数名词：juice #160; chalk #160; tissue #160;（不可数名词没有复数形式）There is some chalk.#160;There is some juice.There is some tissue.九．’s所有格 ：表示：某人或某动物的the girl’s name #160; #160;那个女孩的名字 #160;the teacher’s desk #160; #160; #160; #160;讲台the headmaster’s office #160; 校长的办公室 #160;the children’s #160;toys #160; #160; #160;儿孩子们的玩具the teachers’ #160;room #160; #160;教师办公室 #160;(当名词的复数形式是以“s”结尾时，直接加 ’)十． be 动词 :is #160;are #160;am （ 表示“是” ）I 用am #160;， you 用are ， is 连着he，she ，it 。

单数名词用is ，复数名词全用are #160;如： I am ….#160; You are… .#160; We are… .#160; They are…..#160;He is…..#160;She is…..#160; #160;It is….#160; #160; #160; The girl is ….#160; The boys are….#160; #160;Ben is….#160; #160;Ja and Ben are…第 页 共 页。
