The sports meeting is put off./ is to be put off.

问题描述:

The sports meeting is put off./ is to be put off.
The sports meeting __
A.is put off
B.is to put off
C.is to be put off
D.puts off
为什么C不可以呢?be to do表将来,变成被动语态就是be to be done啊”运动会将会被取消“.

is就是那个be动词了 不需要再重复了呀 而且不是be to do 表将来而是to do表将来 如果用to do的话应该是 is going to be put off
