it's our first time ()the great walla visit b to visit c visited写出为什么?有哪些语法?

问题描述:

it's our first time ()the great wall
a visit
b to visit
c visited
写出为什么?有哪些语法?

B
it's our first time (干什么的第一次)后置定语
由序数词修饰名词时,由不定式作后置定语
如 The last one to arrive pays the meal.
Lily is the first student to get up.
采纳吧

b to visit
it's our first time这是一个句子已有动词be,不能再有其他实意动词了.所以用不定式
