About THAT-clauses

Last week in class (and in my powerpoint) we looked at THAT-clauses as subjects of the sentence. I said that the use of a THAT-clause as the subject is formal.

Here are three ways to say the same thing:
1. That Kemal makes it to class before 9 a.m. is amazing.
2. The fact that Kemal makes it to class before 9 a.m. is amazing.
But more commonly...
3. It is amazing that Kemal makes it to class before 9 a.m.

And another example:
1. That Tarek can't stay awake without his morning coffee is obvious to all of us.
2. The fact that Tarek can't stay awake without his morning coffee is obvious to all of us.
But more commonly...
3. It is obvious to all of us that Tarek can't stay awake without his morning coffee.

And yet another:
1. That my class is a lot of fun is undeniable.
2. The fact that my class is a lot of fun is undeniable.
But more commonly...
3. It is undeniable that my class is a lot of fun.

And finally:
1. That I work very hard is clear.
2. The fact that I work very hard is clear.
3. It is a fact that I work very hard.
