how many的用法：

　　對數(shù)量進行提問，many后面跟可數(shù)名詞復(fù)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(fù)數(shù)一般都用復(fù)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(fù)數(shù)形式,所以be一定要用are.即用Howmany+可數(shù)名詞復(fù)數(shù)+arethere+地點/時間狀語的句型結(jié)構(gòu)。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？
