牛津教材8BU2 Water Talk教案

Chapter 5 Water talk一、教学内容：Chapter 5 Water talk二、重点语法：（一）how much与how many的用法1. 所修饰词的不同how many用来修饰可数名词的复数，它的句式是:How many+复数名词+一般疑问句＋?how much用来修饰不可数名词，表示数量，也可单独使用。

2. how many的用法（1）对there be句型中主语的数量如:some, five, only one等提问时,如果主语是可数名词，不管主语是单数还是复数的一般都用复数形式提问，因为问话人不知道具体的数量是多少，而且many只能接可数名词的复数形式，所以be一定要用are.即用How many+可数名词复数+are there+地点/时间状语？的句型结构.例如:①There is a book on the desk. (用how many改为特殊疑问句)How many books are there on the desk?②There are seven days in a week. (对划线部分进行提问)How many days are there in a week?（2）记忆口诀how many在句首，名词复数跟着走，一般问句紧相随，其它成分不要丢。

3. how much的用法（1）用来询问事物的数量，后接不可数名词。

例如：How much milk is there in the glass? 玻璃杯里有多少牛奶？（2）用来询问事物的重量。

例如：－How much does the pig weigh? 这头猪多重？－Eighty kilos.八十公斤。

（3）how much 意为“多少钱”时，可单独使用，也可构成词组how much money，但英语中常省略money，用来询问某物的价钱、价格。

（注意：how much询问价格时，它的回答若是中国的货币单位应采用汉语拼音yuan, fen 来表示，几角常采用几十分来表示，字母用小写，且不用复数。
