Question

我明天就要考试啦,有关英语方面的问题
——How high do we need to build the wall Is it----?
——No,a------wall is enough.
A three-meter-high；two-meter-high B three-meter-high；two meters high C three meters high ；two-meter-high D three meters high ;two meters high
为什么要选C?

Answer 1

is it 3 meters high ?为一个疑问句,将它还原为陈述句则为it is 3 meters high.
而用2-meter-high 是因为wall 为名词,前面需要的是定语 而2-meter-high的意思为“2米高的”,相当于形容词
