     Many people invented toys. Most of them were kids. Kids are better than adults at inventing toys. They

can use everything to make toys.

     But sometimes adults can make the old ones more popular. For example, People first played yo-yos in

ancient (古代的) Greece. About two hundred years ago they became very popular with children, first in

England and then in the United States. Later people didn't like them, In 1928, Donald Duncan went into the

yo-yo business. He had some "Yo-yo men" and let them go door to door selling yo-yos. Soon more and more

people began to play yo-yos. Today the name Duncan still goes with yo-yo.
