We can tell the time by a clock or watch. A clock is big; it is usually on the wall, or it stands on the table. A watch is small; we can put one in our pocket (口袋) or wear it on the wrist (手腕).

The clock has a round face with figures (数字) on it, and two hands, a long hand and a short hand.

The short hand points to the hours (小时), the long hand points to the minutes(分). Some clock have three hands, a short hand , a long hand, and a very long one to point to the seconds (秒).
