算盘的来历,最早可以追溯到公元前600年,据说我国当时就有了“算板”。古人把10个算珠串成一组,一组组排列好,放入框内,然后迅速拨动算珠进行计算。东汉末年,徐岳在《数术记遗》中记载,他的老师刘洪访问隐士天目先生时,天目先生解释14种计算方法,其中一种就是珠算,采用的计算工具很接近现代的算盘。这种算盘每位有5颗可动的算珠,上面1颗相当于5,下面4颗每颗当作1。随着算盘的使用,人们总结出许多口决,使计算的速度更快了。这种用算盘计算的方法,叫珠算。

At present time, roller skating (滑旱冰) is easy and fun. But many years ago, it wasn’t easy at all. Before 1750, people never tried skating on wheels. That changed because of a man named Joseph Merlin. Merlin’s work was making instruments (工具). In his free time he liked to play the violin. Merlin was a man with many ideas and many dreams. People called him a dreamer.

One day Merlin received an invitation to go to an important party. He was very pleased and a little excited. As the day of the party came near, Merlin began to think. He wanted to find a way to make a wonderful entrance at the party. Merlin had an idea. He thought that he would attract a lot of attention if he could skate into the room.

Merlin tried different ways to make himself roll (滚动). Finally, he decided to put two wheels under each shoe. These were the first roller skate shoes. Merlin was very proud of them. He dreamed of arriving at the party and skating into the room while playing the violin. He was sure that everyone would be very surprised.

On the night of the party Merlin rolled into the room, playing his violin. Everyone was really surprised to see him. There was just one problem. Merlin had no way to stop his roller skating.
