The dictation was checked by the teacher yesterday
If you do not to buy coffee, we shall drink tea
If he didnt smoke, he would not feel so bad
If she had warned me, I would have done the work in time
I have been waiting for a letter from my brother for a month already
You have been playing with a ball for three hours already
He has been working here for five years
