Which of the following can't be used to ask for price?
- A.How much are these pants?
- B.How much do these pants cost?
- C.What's the price of these pants?
- D.What are the price of these pants?
答案
正确答案:D

最后一项中price是单数形式,所以系动词要用is,而不能用are。故选D。

注意最后一项中the price of these pants的中心语是price,是单数形式,所以不能用are。
