In this short video we'll be discussing noun clauses with it and whether. So, noun
clauses with it or whether are just like any other noun clause. They're dependent
clauses, so they need to be attached to an independent clause, and we use it or
whether to introduce these types of noun clauses. We use these types of noun
clauses to change yes-or-no questions into clauses or dependent clauses. We
use statement word order in these types of noun clauses just like the WH
question noun clauses we don't use question word order and we don't use a
question mark at the end of the sentence. if the noun clause is in a statement.
So, let's look at some examples we have this first yes-or-no question
"Are the students studying?" Now he want to try to change this into a noun clause so we
start with the independent clause "the instructor wants to know" We just make this
independent clause up and we're going to add "if" and then we switch the subject
and verb so that their in statement word order so we have "The instructor wants to know
if the students are studying" Here's another example: "Did the students see the email?"
Start with the independent clause "She wonders" then we can use if or whether,
statement word order. She wonders if the students saw the email." So
you can see that in the original question we have the helping verb in the
past tense, subject and then the main verb, and then in the noun clause we have the subject
and the verb as if it was just a statement. "Should they write the email?" Another yes/no
question. We start with the independent class "He's not sure" then we start with "if" or
"whether" and then we have the subject "they should write the e-mail." So we're going to talk about one common error
that a lot of people make a mistake with using these types of noun clauses.
The first error is using 'that' and 'if' or 'whether' to connect the independent clause with
the noun clause, so for example we have "The student wants to know that if there's homework."
So, we can't use both 'that' and 'if' in the sentence. To correct this error, we start with this
error "the student wants to know that if there's homework" We just take out 'that'
and now we have a sentence, a complex sentence with the 'if' or 'whether' noun clause.
