问题: 高二英语

______is the distance between these two cities?
A.How long B.What C.How far D.How

请回答应该选哪个及为什么选。

解答:

应该选B,也就是What is the distance between these two cities?
请注意,问距离多长,一般不能用how long.
类似的例子有:
我们可以说How long is the bridge?
而不能说How long is the length of the bridge?
但我们可以说What is the length of the bridge?
又如我们问年龄时只能说:what is your age?或how old are you?
而不能说:how old is your age?
