Don't you think____important to protect our earth?A that B how C it D this 为什么要选C?

问题描述:

Don't you think____important to protect our earth?A that B how C it D this 为什么要选C?
如果it是作形式宾语后面不是应该是 it is important to protect our earth.为什么是
it important to protect our earth

因为整句句子做think的宾语,所以省略掉了,如果是整句句子的话就需要加上that,即don't you think that it is important to protect our earth?
