Long, long ago there (live) a lot of mice in an old house. There (live) a cat in that house too. The mice (be) afraid of the cat but they (not know) what to do. So one day they all (come) to an old clever mouse and (begin) to talk about the cat.
"What (can) we do?" they (say). "the cat (kill) us all."
Suddenly one little mouse (say), "Let's put a bell round the cat's neck and we (hear) it."
They (be) all very glad and they (begin) to dance.
Suddenly the clever old mouse said, "I (want) to ask you one question. Who (put) the bell round the cat's neck?"
