Discussion Groups / ESL Teaching / July 2004

I have a question about the following sentences:

I don't like it when my brother hits me.
vs.
I don't like when my brother hits me.

Is the former is the only correct way of expressing this idea out of
the two?
The rationale is that "when my brother hits me" is a subjunctive
adverbial clause.  Thus, that part should be able to be removed and
still have a correct sentence ("I don't like") in the latter case,
which sounds odd.

On the other hand, the latter sentence is heard very often.  Is it
incorrect?

If it is NOT incorrect, can someone explain to me in grammatical terms
why it is acceptable?

Thanks!
