A.it
B.that
C.both
D./
选择D解释为什么不选A
归纳make it possible和make possible
两者区别和 在什么情况下选哪个。谢谢

Answer 1

make it possible +that + 宾语从句 其中it作为形式宾语
至于区别从例句来看：
The invention of telegram make possible the transmission of messages to any part of the world within a few second.
The invention of telegram make it possible for message to be transmitted to any part of the world within a few second.
make possible 直接加n.就不需要it 这个形式宾语
有没有it要从整句句子的语境来看
→形式宾语即当宾语太长的时候,习惯性的放在最后,本来的位置就用it顶上.
1 make sth（直接加宾语） possible:Hard work plus a little wisdom has made John's success possible (直接加宾语)
2 make it(只能用it) possible for sb.to do sth.或者make it possble that 加句子
如：A) Hard work plus a little wisdom has made it possible for John to succeed in his job.
B) Hard work with a little wisdom made it possible that John succeeded in his job.
