Let’s look at two old but popular inventions we use in our daily life.

Band-Aids（創(chuàng)可貼）

The first Band-Aid was made by American Earle Dickson in 1921. The idea came to him by chance. Dickson’s wife Josephine often cut her fingers in the kitchen. At that time gauze（紗布） and adhesive tape（膠帶）didn’t come together. People had to cut them to the right size. Dickson found they were always too big and soon fell off. So he put a piece of gauze on the center of a piece of tape. This is how he made the first Band-Aid.

Later Dickson’s new inventions became very popular all around the world.

Bubblegum（泡泡糖）

Bubblegum was invented by accident. In 1928, American gum company worker Walter E. Diemer played around with new chewing gum recipes. Chewing gum had already been invented more than half a century before then. But Diemer found that the gum he made was easy to blow. He blew a bubble and then saw the possibilities. He took some of his new gum to a shop and it sold out in a single afternoon. Since then, Dubble Bubble—the first brand of bubblegum—has made kids happy all around the world.

1.Josephine often _________ in the kitchen.

A. hurt her fingers B. made bubblegum

2.Before the Band-Aid was invented, _________.

A. the gauze and adhesive tape were always small
