how many的用法：
對(duì)數(shù)量進(jìn)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(duì)therebe句型中主語的數(shù)量如:some,five,onlyone等提問時(shí),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?yàn)閱栐捜瞬恢谰唧w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(diǎn)/時(shí)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(duì)劃線部分進(jìn)行提問)How many days are there in a week 翻譯：一周有多少天？
