The little clock in the sitting room struck the hour.

When the clock struck six, he got up, and went to the door.

Just as the clock struck six, the heat began to come up.

By the time the clock struck 12, about a hundred people were on hand.

The clock struck half past eight when I came in, didn't it?

One night in every week, as the clock strikes ten, we meet.

When the clock struck 12 all the lights of the city went dead.

The clock struck five thirty as we turned on to the A469.

The grand clock in the hall struck the hour of five.

But the real challenge for you will come after that clock strikes 12.
