명사절 만드는 순서 어떻게 되요?

명사절은 '주어', '보어', '목적어'로 쓰여야 됩니다. 또한 '주어+동사'를 반드시 포함 시켜야 되죠.

1. 주어로 쓰인 경우

What I have to do today is finishing all homework.

That there is a fact that we should study hard is our duty.

2. 보어로 쓰인 경우

1) The important thing is that he is right. (주격보어) 

2) the question is whether he is right.(or not) 

3) the question is what you have.

4)it is when we have to start.

5) this is how we solved the problem. 

3. 목적어로 쓰인 경우

I want to know if he will be here.
