一道单选题？急求。谢谢。在线等哦

I don't think _____ possible to master a foreign language without much memory work.
A this B that C its D it
选D 为什么不是it's

Answer 1

it is adj to do sth是个消者租培基本句型。
但前面有think 后面的就是think的从句了。所拿型薯以不能再有is
think (that)+从句
故而选it

Answer 2

i don't think it possible 已郑哗颂经是喊郑一个完整的句子了.

当然, it is 或者 it'芦游s 都是可以的. 可是你这里没有.

Answer 3

如果有，当然可以选。隐庆缓。
think it adj. to do=think it is adj. to do

Answer 4

应该是it's啊，不知道三楼在说什么，从句也要完整啊

Answer 5

it&it's都对
