對there be句型中主語的數(shù)量如:some, five, only one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How many+可數(shù)名詞復數(shù)+are there+地點/時間狀語的句型結(jié)構(gòu)。
例句:
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?
