first of all 首先

Unit 10 I’d like some noodles.★1.(P55,题目)①would like sth想要某物

H ’d like a new pen,他想要一支新钢笔。

② would like to do sth想做某物

We ’d like to play basketball.我们想去打篮球。

★ 2.(P55,1a) 可数名词的单数变复数规则(规则变化):①绝大多数名词的复数形式是在名词词尾加s

例如:bag—bags,apple—apples;

②以辅音字母 y结尾的名词,先变y为i,再加es

例如:family- families,dictionary- dictionaries;

③在以s,sh,ch,x结尾的名词后加es。

例如:Class - Classes,watch(手表)-watches;

④在以f或fe结尾的名词,变f或fe为ve再加s

例如:wife-wives,leaf-leaves;

⑤以o结尾的名词,有生命的加es,没有生命的s

例如:tomato-tomatoes,piano-pianos,zoo-zoos

可数名词的单数变复数(不规则变化):

man-men;woman-women;child-children;chinese- chinese(中国人);Japanese- Japanese(日本人)

补充:关于名词修饰名词的单复数问题:

名词修饰名词时,

例如:an apple tree(一棵苹果树)中apple(名词,苹果)修饰tree(名词,树),对tree进行修饰和限制,说明这棵树不是橘子树也不是梨树,只能是苹果树。

一般情况,像这样名词放在名词前做定语,起修饰作用时,前面的名词只能使用单数形式。该短语变为复数时,只有后面的名词变为复数,

例如:

tomato noodles(西红柿面条) 中tomato只能使用单数形式 本单元中同样的短语还有:

potato salad (土豆沙拉) beef and carrot noodles (牛肉和胡萝卜面)

但是,可数名词单独作为某道菜时,需要用复数形式

例如:I like tomatoes,but I don’t like beef .我喜欢吃土豆,但是不喜欢吃牛肉。(tomato为可数名词,beef为不可数名词)

★ 3.(P55,图片)some与any的用法:① some(一些,很多)一般用于肯定句中,后面跟可数名词复数和不可数名词。② any(一些,很多)一般用于否定句中,后面跟可数名词复数和不可数名词。③ some有时也可以用于疑问句中,表示说话人已了解一些情况,希望得到肯定回答。

Tom has some books.汤姆有许多书。(book为可数名词)(肯定句)→

Tom doesn't have any books.(否定句) Does Tom have any books?(一般疑问句)

There is some water in the bowl.在碗里有一些水。(water为不可数名词)

Would you like some noodles? 你想来些面条吗?(希望得到对方肯定回答)

4.(P56,2b,1行)关于量词的单复数问题

bowl(碗)、glass(玻璃杯)为量词

a bowl of rice(一碗米饭)

→two bowls of rice(两碗米饭) (rice不可数,但是bowl可数)

a glass of juice(一玻璃杯果汁)

→three glasses of juice(三玻璃杯果汁)

★ 5.(P58,1b)and(和)用于肯定句表示并列,or(或者)用于疑问句、否定句表示并列

I like noodles,tomatoes and orange juice.我喜欢面条,西红柿和橘子汁。(肯定句)→

I don't like noodles,tomatoes and orange juice.(否定句)

★ 6.(P2b,2段2行)the number of 名词:…的数量(该短语放在句首做主语时,句子动词用单数形式)
