Every time the hand of the clock runs a circle,they grow up a little.
This short vedio lasts 3 minutes only.It is a story about the whole life of a couple.It will tell you how they met,how they fell in love with each other,and how they to be old.
注:1.钟摆即指针,生活化的说法是hand.因此最好加上是时针还是分针走一周,他们长大一点点.hour hand 时针 minute hand 分针
2.时钟自己不会walk or run,是它的指针 walk or run.这两个词用哪个都可以.看你强调时间过的快还是慢.
