While drunken driving may be on the decline, traffic safety experts remain puzzled over how to deal with another alcohol?related danger: drunken pedestrains.
Pedestrians struck and killed by cars often are extremely drunk. In fact, they are intoxicated more frequently-and with higher blood?alcohol levels-than drunken drivers who are killed in accidents, various studies have shown. Forty percent of adult pedestrians involved in fatal crashes have a blood?alcohol level of at least 0.10-which by law in most states signifies intoxication-compared to only 25 percent of drivers in deadly accidents, according to recent federal data.
Some types of pedestrain accidents have been declining nationally, especially those involving children, but the number of adult pedestrians who are drunk when killed in traffic has remained relatively steady at 2500 a year. The total number of pedestrians killed annually in U.S. traffic accidents is at least 7000, or one of every seven highway accidents resulting in death.
“We’re dealing here, we think, with a very severe drinking problem that leads to a severe highway safety problem,” said Richard Blomberg, president of Dunlap and Associates Inc, in Norwalk, Coon.
Blomberg, whose consulting company found a very high rate of alcohol involvement in a controlled study of pedestrian accidents in New Orleans, was among several researchers who spoke on the topic at the annual meeting of the Research council’s Transportation Research Board(TRB) in Washington in January.
Pedestrian accidents have not received enough attention in the past, according to Kay Colpitts, who chairs the board’s committee on pedestrians. Few methods exist to monitor walking habits, she said, and researchers have been mystified about how to prevent disasters.

D.make up one?seventh of highway accidents
8.According to the passage, what is Blomberg?
A.A researcher. B.A specialist in traffic safety.
C.A clerk of a consulting company. D.A government official
5-8 CBAA
5.C 本文主题是讲解醉酒行人出交通事故的问题，所以答案为C。A为交通安全，虽然文章有所涉及，但涉及面太广；B为喝醉的司机，文章虽提到．但是并非文章讲述对象；D为严重的公路安全问题，也犯了涉及面大广的错误。
6.B 见文章第二段第一句:Pedestrians struck and killed by cars often are extremely drunken. 说明醉酒是主要原因,故答案为B。
7.A 第二段中第三句提到在致命车祸中成年行人喝醉的占40%，而司机酒醉的只有25%，40%-25%=15%。与A的意思一致。
8.A 此题可从文中第五段找到答案。每年1月，调查委员会在华盛顿召开交通研究会议，Blombery是在会上发言的研究人员之一
。他的咨询公司在新奥尔良地区行人事故的对比研究中发现，酒精肇事在行人交通事故中的比率非常高
所以Blomberg是一位研究人员。

Today, ultrasonic(超声的) waves are being put to work in laboratories and factories. If an ultrasound generator is placed in a liquid, the waves move the liquid back and forth hundreds of thousands of times each second. This causes materials to mix quickly or to dissolve(使分解，使溶解) in liquids. Paint manufacturers(制造商) use ultrasound to do a better job of blending colors. The companies that make film for your camera find that mixing chemicals by the use of sound waves will produce a more sensitive film.
The new lightweight(轻量的) type of washing machine uses ultrasonic waves to get clothes clean. Its special ultrasound generator is put into a pail of soapy water containing the soiled clothes. The sound waves drive the soapy water back and forth through the cloth so fast that everything is soon clean. There is also a new kind of dishwasher that works in much the same way.
Ultrasonic waves can shake a liquid so fast that tiny holes form all through it. The liquid is actually torn apart by this action. Almost as soon as these holes are made, they fall together again. The result is a powerful pounding action. In the dairy industry this is used for the double purpose of making homogenized(使均匀，使匀质) milk and sterilizing(使无菌) it at the same time. If you look at some raw milk with a microscope, you find that it is made up of little drops of butter fat floating around in a watery liquid. In order to make milk easier to digest, these fat droplets(微粒) may be broken up by forcing the milk through very small openings. The result is called homogenized milk. When the ultrasonic method is used, the sound waves not only break up the droplets but also kill the germs in the milk by pounding them to pieces. (from www.nmet84.com)
8. Why does a paint manufacturer use ultrasound to do a better job of blending colors?
A. Because it is cheap to use ultrasound to blend colors.
B. Because the waves move the liquid so quickly that it can make materials mix quickly or dissolve in liquids.
C. Because they can mix chemicals by the use of sound waves.
D. Because the waves can clean the paint.
9. What properties does ultrasound wave have?
A. Homogenizes and sterilizes the milk. B. Mix materials and break droplets.
C. Kill germs and sterilize milk. D. Move liquids quickly.
10. What exists in the raw milk?
A. Little drops of butter fat. B. Small holes. C. Fat droplets and germs. D. Chemicals.
11. Where is ultrasound wave not used?
A. In the paint manufacture. B. In the shop mixing bread flour.
C. In the film-making company. D. In the dairy industry.

If you walk through the streets of any big city at six or seven in the morning, the chances are that you will see women hurrying along, pushing prams (婴儿推车). You may see more than one woman 1 on the same door and, as it opens, quickly kiss the child, 2 a package of nappies and hurry off down the street to clock on the early shift in an office, leaving their children to a child – minder – a woman who may be doing the job legally or illegally, well or badly. Brain Jackson, director of the Child – minding Researching Unit, and his colleagues have done a great deal of work in finding out 3 it means for a child to spend the first years of life in the care of a child – minder.
4 law, anyone who looks after a child for more than two hours a day and gets paid must be registered. 5 the punishment is a 6 pounds fine. Local authorities are responsible for the registration and supervision (监管) of minders. The regulations 6 adequate provision (保障) for fire, safety and health. Very few minders can 7 these. Yet, not many districts give financial assistance. “This means,” Brain Jackson says, “that when you have one registered minder tested and proved by the local authorities, you can be sure that you will get a dozen unregistered, illegal minders 8 .”
The researchers found themselves 9 into the role of private investigators when they conduct their 10 . Getting up early to do a “Dawn Watch” following mothers through cold, dark streets and nothing where they left their babies, Jackson says, was a long, slow process.
