[疑、难点解析] 1.句型 (1)How many bottles of orange can you see?你能看见几瓶桔汁呢? how many(有多少,指可数名词),how much(有多少,指不可数名词)等后面要用疑问句式表达. 如:How many bananas can you see? 你能看见多少只香蕉呀? How much milk do you have? 你喝了多少牛奶呀? (2)I can see only one.我只能看见一个. Only在此句中是副词,修饰动词see,不能看做是形容词修饰one, one只是一个代词. 如:Only a student is from China. 只有一个学生是中国人. only作形容词,它前面往往有one’s或定冠词the出现. 如:He is the only American student in our class. 他是我们班上唯一的美国学生. 2.不可数名词 名词分为可数名词和不可数名词两种.物质名词和抽象名词是不可数名词.不可数名词一般不用a/ on或the来修饰.但强调时,可在前面加定冠词the,不可数名词没有复数形式. 如:food, meat, bread, tea, water, milk, ink, orange(桔汁), drink(饮料), rice, fish等. (1)不可数名词要表示“一个”这类概念时,要用下列短语: a cup of tea 一杯茶 a bottle of orange 一瓶桔汁 a glass of milk 一杯牛奶 a piece of bread 一块面包 (2)表达复数意义时应用下列方式 two caps of tea 两杯茶 three bottles of drink 三瓶饮料 另外也可以用some, any, much, a little, a lot of等修饰不可数名词. 例如:There is some water in the cup.在杯子里有些水. Can you give me some ink?你能给我些墨水吗? I don’t want any milk.我不要牛奶. (3)would like “想要”表示请求或个人想法,看法等,语气婉转客气. I’d like == I would like I’d like do sth. +n. 如:I’d like to go there.我想要去哪儿. I’d like some bananas.我想要些香蕉. (4)It’s time to do sth. for + n. for sb. to do sth. 如:It’s time to get up.该起床了. It’s time for the meeting.开会时间到了. It’s time for your to play games.现在该你做游戏了.
