As a young girl, Margaret “Mattie” Knight never played with dolls, preferring to make toys for her brothers instead. In 1849, Knight went to work in a cotton factory where she witnessed a “shuttle,” a device that carries thread back and forth across a textile loom（纺布机）, fly off the machine when the thread broke, striking and killing a young boy about her own age.

The 12-year-old Knight developed a safety mechanism that made it impossible for a shuttle to leave the loom. The design was so effective, soon virtually every new power loom carried her invention, saving countless workers from injury or death. Being so young, she didn’t bother to patent the device, so she never received payment.

Knight wouldn’t make the same mistake later in life when she invented a machine that could produce flat-bottomed paper bags. Knight had built a small wooden model in her home, but she needed a metal version to show it could hold up to the stress of mass production. So she hired Charles Annan to make the full-sized machine for her, only to have him try to claim the patent for himself. When Knight sued（起诉）, Annan’s argument was that the design had to be his, because no woman could possibly understand the complex mechanics. Knight proved him wrong when she brought back her wooden prototype and explained how every part worked. She won the case in 1871, making her the second woman to hold an American patent. Over a hundred years later, her design is still used as the basis for many modern flat-bottom bag machines.

But that wasn’t the last the world heard of Mattie Knight. During her lifetime, she made about 90 inventions and received 26 patents, becoming one of the most productive female inventors of the 19th century.

4.What would be the best title for the text?

When I was growing up, I had an old neighbor named Dr. Gibbs. He didn’t look like any doctor I’d   36  known. When Dr. Gibbs wasn’t   37  lives, he was planting trees.

The good doctor had some   38  theories on planting trees. He believed in “No pains, no gains”. He never   39  his new trees, which was   40  many people. Once I asked why. He   41  that watering plants spoiled them, and that if you water them, each following tree generation will   42  weaker and weaker. So you have to make things   43  for them. He talked about how watering trees   44  shallow roots, and how trees that weren’t watered had to grow deep roots in   45  of water. I came to understand that he meant deep roots were to be   46 . I planted a couple of trees a few years back and I took good care of them. Two years of   47  has resulted in trees that expect to be waited on hand and foot. Whenever a cold wind blows, they   48  and tremble their branches. Funny things about those trees of Dr. Gibbs’. The lack of water seemed to   49  them in ways comfort and ease never could.

I used to   50  for my sons that their lives will be easy. But   51  I’ve been thinking that it’s time to   52  my prayer. I know my children are going to meet   53 , and I’m praying they will be strong. The prayer for comfort is seldom met. What we need to do is to pray for deep roots,   54  when the winds blow, we won’t be   55  away.
