How many pencils do you have? 你有多少支鉛筆?

(1)how many是“多少,幾個(gè)”的意思。how many用來(lái)修飾可數(shù)名詞的復(fù)數(shù),它的句式是:How many + 復(fù)數(shù)名詞 + 一般疑問(wèn)句+?

(2)how many的用法:

對(duì)there be句型中主語(yǔ)的數(shù)量如:some, five, only one等提問(wèn)時(shí),如果主語(yǔ)是可數(shù)名詞,不管主語(yǔ)是單數(shù)還是復(fù)數(shù)一般都用復(fù)數(shù)形式提問(wèn),因?yàn)閱?wèn)話(huà)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“how many + 可數(shù)名詞復(fù)數(shù) + are there + 地點(diǎn)/時(shí)間狀語(yǔ)?”的句型結(jié)構(gòu)。

e.g. There is a book on the desk.(用how many改為特殊疑問(wèn)句)

How many books are there on the desk?

There are seven days in a week.(對(duì)劃線(xiàn)部分進(jìn)行提問(wèn))

How many days are there in a week?

(3)記憶口訣

how many在句首,名詞復(fù)數(shù)跟著走,一般問(wèn)句緊相隨,其它成分不要丟。
