chapter 24 A clock and a watch
We can tell the time by a clock or by a watch. A clock is big; it is usually on the wall or on the table. A watch is small; we can put it in the pocket, or wear it on the wrist! A clock or a watch usually has a round face. It has two hands, a long one and a short one. Tom''s clock can speak and call him to get up every day. His watch has a picture of a lovely dog on the face. He likes it very much.
我们通过时钟或手表来知道时间。时钟是大的，它通常挂在墙上或放在桌子上。而手表是小的，我们可以把他放在口袋里，或者戴在手腕上！时钟或手表通常有一张圆圆的‘脸蛋’。它有两根针，一条长的一条短的。汤姆的钟每天都能叫他起床。他的手表上面有一个可爱的狗狗图片。他非常的喜欢它。
