英语阅读理解答案
The zipper is a wonderful invention. How did people ever live without zippers? Zippers are very common, so we forget that they are wonderful. They are very strong, but they open and close very easily. They come in many colors and sizes.
In the 1890s, people in the United States wore high shoes with a long row of buttons, too. People wanted an easier way to put on and take off clothes.
Whitcomb L. Judson invented the zipper in 1893. He was an engineer in Chicago. He called the zipper a slide fastener. However, it didn’t stay closed very well. This was not satisfactory, and people didn’t buy many of them. Then Dr Gideon Sundback from Sweden solved this problem.
A zipper has three parts: 1. There are dozens of metal or plastic hooks(called teeth) in two rows. 2. These hooks are fixed to two strips of cloth. The cloth strips can bend easily. 3. A fastener slides along and fixes the hooks together. When it slides the other way, it takes the hooks apart. 提问时间：2020-10-30
