I ______ so busily recently that I ______ no time to help you with your math— That’s OKI can manage it by myself

I think we should always stay away from drugs.- They are dangerous and addictive.

There __________a Christmas party in Sunshine Secondary School next Friday evening.

They all said that the man caused the accident, but he ________ he had nothing to do with it.

When I fail and want to give up, my teacher always encourages me ___________ in myself and have confidence in myself.
