The air bag is a piece of safety equipment in cars. It was first designed by John W. Hetrick in 1952. Like many inventions, he came up with the idea as a result of an event that had occurred in his life. He says:
“In the spring of 1952, my wife, my seven-year-old daughter, Joan, and I were out for a Sunday drive in our 1948 Chrysler Windsor. About three miles outside Newport we were watching for deer jumping across the road. Suddenly, there was a large rock in our path. I hit the brakes and we went into a ditch(壕溝).
“As I applied the brakes, both my wife and I threw our hands up to keep our daughter from hitting the car. There was soft mud in the ditch, so the car wasn’t damaged, and no one was hurt.”
“During the ride home I couldn’t stop thinking about the accident. I asked myself,‘Why couldn’t some object come out to stop you from striking the inside of the car?’As soon as I got home that night I drew some sketches(草圖). Each evening for the following two weeks, I’d add or reduce something from the sketches.”
Hetrick applied an event he had observed while in the Navy to the design of the air bag. He was repairing a torpedo(魚雷) which had a cloth covering. When the compressed(壓縮的) air that was in the torpedo was let out, the covering was suddenly filled with air and was shot to the ceiling.
With this knowledge, he developed his design until he was able to obtain a patent on the invention on August 5, 1952. The idea was similar to the air bag designs of today. Compressed air is stored in a container and when a traffic accident occurs and the car slows down at a rapid enough rate, the air will be released into the air bag. The idea was ingenious, but Hetrick’s air bag never would have functioned properly. It was really a breakthrough, but it would require years and years of designing and testing by some top car designers before it could be used.

A.turned out to be dangerous | B.was helpful to his invention |

Researchers at Massachusetts General Hospital for Children (MGHfC) have invented a new term that describes dangers associated with cigarette smoke: third-hand smoke. Study results published in January, 2009 discuss how third-hand smoke is especially dangerous for children.
Have you ever walked into a room that had the smell of cigarette smoke, regardless of the fact that a fan was moving the air and no one was smoking at the time? This is what researchers are calling third-hand smoke — and it represents the poisonous deposits (存積物) that are left behind long after a cigarette is put out.
Cigarette smoke contains gases and small particles that are deposited on every surface it comes in contact with, for example, the smoker’s hair and clothing, or the environment the cigarette was smoked in. It’s dangerous for young children who may crawl on polluted surfaces. Third-hand smoke is a serious health risk for our kids, especially those who live in the homes of smokers.
Jonathan Winickoff, lead author of the study, explains, “When you come into contact with your baby, even if you’re not smoking at the time, he or she comes in contact with those poisons. And if you breast-feed, the poisons will transfer to your baby in your breast milk.” Winickoff adds however, that nursing a baby if you’re a smoker is still a better choice than bottle-feeding.
Researchers involved in the study also surveyed more than 1,500 families in an effort to learn about adult attitudes regarding the danger third-hand smoke represents to their children and how that might affect smoking in the home.
Approximately 95 percent of nonsmokers and 84 percent of smokers believe that secondhand smoke is dangerous for children.
On the issue of whether third-hand smoke threatens the health of children, 65 percent of nonsmokers and 43 percent of smokers felt that third-hand smoke harms kids. When asked about rules regarding smoking in the home, approximately 88 percent of nonsmokers said they don’t allow smoking, while only 27 percent of smokers forbid smoking in the home.
However, both non-smokers and smokers who felt that third-hand smoking was harmful to children’s health were more inclined to (傾向于) restrict smoking in their homes.
【小題1】The study led by Jonathan Winickoff focused on _______.
A.bad influences long after a cigarette is smoked |
B.third-hand smoke and secondhand smoke |
C.the bad effects of smoking on common people |
D.the terrible smell of cigarette smoke |
A.By telling results of a survey. |
B.By giving statistics. |
C.By making comparisons. |
D.By giving an example. |
A.keeping kids out of room when you smoke |
B.cleaning the house to get rid of poisons |
C.making yourself clean before contacting kids |
D.trying to forbid smoking in home |

Some years ago I worked with people on public welfare. I believed that everybody had the ability to be 26 and all we have to do was to make them start working.
The first thing I said to them was, "I would like to know what your 27 are." Everyone looked at me as if I were 28 . One woman said "I don't know what you can 29 with dreams. The rats are eating up my kids." I said. "That's terrible. You are very much 30 with the rats and your kids. How can we help?" " I could use a new screen door(紗門)because there are 31 in the old." I asked, "Is there anybody knowing 32 to fix it?" A man said, "Long ago I used to do things like that but now I have a bad back, but I'll 33 ." I gave him some money to do that.
The next week, when the group was 34, I asked the woman, "Well, is your 35 door fixed?" "Oh, yes," she said. "Then we can start dreaming, right?" She 36 at me. I asked the man, "How do you feel?"

I said, " What 40 in your way?" She answered, "I have six kids, and no one can 41 them while I'm away." I asked "Who would help this woman while she gets some 42 at school?" Another woman said "I got kids, too, but I could do that." So the woman went to school.
In 12 weeks these people were 43 public welfare. The woman who 44 the children became a licensed foster care (代別人照看孩子)person. The man became a handyman. I've not only done that 45 , I've done it many times.
