Did you ever wonder who invented products

题目内容：

Did you ever wonder who invented products like Liquid Paper, Kevlar or paper bags? Most would think a man invented these items. Guess what? Women invented each of these. What? You don’t believe me? Well, read this:

Liquid Paper was invented by Bette Nesmith Graham in 1951 and originally called Mistake Out. Being a typist, Bette was increasingly irritated with being unable to erase her typing mistakes. The messy business left her hands black and the paper dirty. Bette was good at painting and remembered that an artist paints over mistakes. She applied that same principle to typing mistakes and Liquid Paper was born, making Bette into a self-made millionaire.

Kevlar, yes, the Kevlar of the bullet proof vest（防弹衣）—what police officers and soldiers wear, was invented by Stephanie Kwolek. Stephanie worked for the DuPont Company as a research chemist. She was asked to find a high-performance fiber. Originally, this fiber was intended to be used for car tires (轮胎). However, the fiber she developed in 1964 was amazing and is still used in products such as sailboats, skis, shoes, and yes, bullet proof vests. In 1995 Stephanie was named to the National Inventor’s Hall of Fame.

Margaret Knight invented a machine that revolutionized the making of paper bags. Paper bags had been made like envelopes but Margaret developed a machine that would fold and paste（粘）a flat-bottom paper bag, the very same type we still use today. Margaret’s family was poor and she started working at the age of nine. Her first invention at the age of twelve was a safety tool for a loom（织布机）. Later she worked for the Columbia Paper Bag Company. It was there that she worked on improving the making of paper bags. She was issued her patent（专利）in 1870.

So next time you use a new product or an old one, will you wonder who made it? Do some research on the web and answer a few questions like: Who invented it? How was it invented? You may be surprised at some of the stories you uncover.
