The cat is lost. We are all ________ it.

I called you this morning, but nobody answered it.– Oh, we ______ some shopping at the supermarket.

You look tired! working in door you should be out for a walk.[ ]

By the end of the last month, I _____________ all the CDs of Justin Bieber.

I don’t expect children to be rude, nor ______ them to be disobeyed．
