The dictation (to check) by the teacher yesterday
If you (not to buy) coffee, we shall drink tea
If he (to smoke), he would not feel so bad
If she had warned me, I (to do) the work in time
I ( to wait) for a letter from my brother for a month already
You (to play) with a ball for three hours already
He (to work) here for five years
