Whatever Rock was doing down there, it made enough noise for me to go to him. By the time I made it to the bottom of the stairs, he was running up, and he never came up the stairs, no matter what. I think that was his way of telling me, “We’ve got to go back up.”

When I got to the top of the stairs, I turned around and saw a light on, but I didn’t remember leaving one on. I walked downstairs again, and that’s when I saw fire, I immediately shouted to my wife to wake up and get our three kids, I grabbed a knife and cut out the plastic that covered the window to the porch roof. I then broke the window and kicked out the screen. I got everybody out on the roof and threw a blanket out there so we wouldn’t slip off. It was cold, January cold. Then I started screaming for help. But help never came.

Now, I’m scared of heights and have physical issues, what with my rheumatoid arthritis(类风湿性关节炎), but I couldn’t let my family burn up. So I jumped off the roof. I didn’t run to the edge; I just jumped and got the wind knocked out of me when I landed.

I found our ladder, placed it against the house, and climbed back up to the roof. I wrapped my arms around my daughter and carried my nine-month-old son with my teeth, by his little sleeper. Then I climbed down the ladder. Once on the ground, I had my little girl hold her brother, and I went back up to the roof to get my other daughter. Then I went back up again and got my wife. I tried to get my dog, but he just disappeared in the black smoke. I never saw him alive again.

I’m no hero. I’m just an ordinary person who’d help anybody. This happened to be the time when I helped my own family. I live to protect my family. Just like Rock—he lived to protect us.

Humans have sewn by hand for thousands of years. It was said that the first thread was made from animal muscle and sinew (腱). And the earliest needles were made from bones. Since those early days, many people have been involved in the process of developing a machine that could do the same thing more quickly and with greater efficiency.

Charles Wiesenthal, who was born in Germany, designed and received a patent on a double-pointed needle that eliminated the need to turn the needle around with each stitch (缝合) in England in 1755. Other inventors of that time tried to develop a functional sewing machine, but each design had at least one serious imperfection. Frenchman Barthelemy Thimonnier finally engineered a machine that really worked. However, he was nearly killed by a group of angry tailors when they burned down his garment factory. They feared that they would lose their jobs to the machine.

American inventor Elias Howe, born on July 9, 1819, was awarded a patent for a method of sewing that used thread from two different sources. Howe’s machine had a needle with an eye at the point, and it used the two threads to make a special stitch called a lockstitch. However, Howe faced difficulty in finding buyers for his machines in America. In frustration, he traveled to England to try to sell his invention there. When he finally returned home, he found that dozens of manufacturers were adapting his discovery for use in their own sewing machines.

Isaac Singer, another American inventor, was also a manufacturer who made improvements to the design of sewing machines. He invented an up-and-down-motion mechanism that replaced the side-to-side machines. He also developed a foot treadle(脚踏板) to power his machine. This improvement left the sewer’s hands free. Undoubtedly, it was a huge improvement of the hand-cranked machine of the past. Soon the Singer sewing machine achieved more fame than the others for it was more practical, it could be adapted to home use and it could be bought on hire-purchase. The Singer sewing machine became the first home appliance, and the Singer company became one of the first American multinationals.

However, Singer used the same method to create a lockstitch that Howe had already patented. As a result, Howe accused him of patent infringement（侵犯）. Of course, Elias Howe won the court case, and Singer was ordered to pay Howe royalties（版税）. In the end, Howe became a millionaire, not by manufacturing the sewing machine, but by receiving royalty payments for his invention.

1.Barthelemy Thimonnier’s garment factory was burned down because _____________.

A. people did not know how to put out the fire

B. Elias Howe thought Thimonnier had stolen his invention

C. the sewing machines was couldn’t work finally

D. workers who feared the loss of their jobs to a machine set fire

2.Which of the following is NOT TRUE according to the passage?　　

A. Singer is an American inventor and manufacturer.

B. The Singer sewing company became more practical.

C. The foot treadle helped to make the sewer’s hands free.

D. Singer made improvements to the design of sewing machines.

3.Why did the court force Isaac Singer to pay Elisa Howe a lifetime of royalties?

A. Because the judge was against Singer for his surly attitude.

B. Because Howe had already patented the lockstitch used by Singer.

C. Because Singer had borrowed money from Howe and never repaid it.

D. Because Singer and Howe had both invented the same machine.

4.Which of the following would be the best title for this passage?

A. A Stitch in Time Saves Nine

B. The Case between Howe and Singer

C. Patent Laws on the Sewing Machine

D. The Early History of the Sewing Machine
