用來詢問事物的數(shù)量，后接不可數(shù)名詞，例如：How much milk is there in the glass 玻璃杯里有多少牛奶;用來詢問事物的重量，例如：How much does the pig weigh 這頭豬多重?

how many的用法

對數(shù)量進行提問，many后面跟可數(shù)名詞復數(shù)。

How many pandas are there?

那里有多少只熊貓?

How many lions can you see?

你能看到多少只獅子?

對therebe句型中主語的數(shù)量如:some,five,onlyone等提問時,如果主語是可數(shù)名詞,不管主語是單數(shù)還是復數(shù)一般都用復數(shù)形式提問。

因為問話人不知道具體的數(shù)量是多少,而且many只能接可數(shù)名詞復數(shù)形式,所以be一定要用are.即用Howmany+可數(shù)名詞復數(shù)+arethere+地點/時間狀語的句型結構。例如:

1、There is a book on the desk. (用how many改為特殊疑句)How many books are there on the desk 翻譯：有多少本書在桌子上？

2、There are seven days in a week. (對劃線部分進行提問)How many days are there in a week 翻譯：一周有多少天？
