我有一個好朋友。它有一張圓圓的臉。在它的臉上，有三只手。一個是短的，另外兩個是長的。它沒有胳膊，但它的手轉(zhuǎn)啊轉(zhuǎn)。它沒有腳也沒有腿，但是它可以整天整夜地走。它沒有眼睛和耳朵。它沒有嘴巴，但是它會說話。早上它可以叫醒我，告訴我：“該起床了。”

它是什么呢？

WHAT IS IT?

I have a good friend. It has a round face.On its face, it has three hands. One is short,the other two are long. It has no arms, but its hands turn round and round. It has no feet or legs, but it can go all day and all night. It has no eyes and no ears. It has no mouth, but it can talk. In the morning it can wake me up and tell me, “It’s time to get up.”

What is it?
