二、名詞單數變複數,一般都把s加。

特殊變化有以下:

單數複數一個樣,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結尾,+es (bus-buses, box-boxes, brush-brushes,

watch-watches)

5、以0結尾(有生命的o)+es (tomato-tomatoes)(番茄)例外:kangaroo- kangaroos

6、以輔音字母+y結尾,改y爲i+es ( lady-ladies, baby-babies study-studies)

7.以f或fe結尾,改f或fe爲v+es (knife- knives shelf-shelves)

三、have與has的區別:

have, has都是“有”,

它們的用法有講究,表示“某人有某物”,have, has請記住。 he, she, it “有”用has,I, we , they , you都用have。主人單數用has ,主人複數用have。

have就是能力強,疑問( ?)否定(don’t / do not)都用它。

四、have,has與there is , there are的區別

五、Some與any的區別:

some用於肯定句中,any用於否定句和疑問句中。

如:I have some books. I don’t have any books. Do you have any books ?

六.a與an的區別

一般來講,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動詞用is還是用are由最靠近它的第一個名詞是單數還是複數決定。)

如:There is a book and some pens on the desk. There are some pens and a book on the desk.

八.不可數名詞:

juice chalk tissue (不可數名詞沒有複數形式)

There is some chalk. There is some juice. There is some tissue.

九.’s所有格:

表示:某人或某動物的

the girl’s name那個女孩的名字the teacher’s desk講臺

the headmaster’s office校長的辦公室the children’s toys兒孩子們的玩具

the teachers’ room教師辦公室(當名詞的複數形式是以“s”結尾時,直接加’)

十. be動詞:

is are am (表示“是” )

I用am,you用are,is連着he,she,it 。單數名詞用is,複數名詞全用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…
