求解高考原题how amazing it is that astronauts are……
-how amazing it is that astronauts are exploring outer space.
-it's a challenge,i guess,____man against nature.
答案填of,为什么不能是about?

Answer 1

1.it's a challenge,i guess：我想那是一个挑战,人类征服自然（的） 挑战
如果将i guess前置,
i guess是插入的,可以不看,如果将它前置,就明显的看出来这里需要的是一个所有格“of".
I guess it's a challenge____man against nature.
而against是一个介词,如果about再作为介词放在前面显然不可以.
