    Maurice Mountain is a retired lawyer in Washington, D.C. He developed a prototype(原型机) for a device he calls the Presto Emergency Boat Ladder. His invention is a small folding ladder that attaches to the side of a boat to help people who fall into the water. Mr. Mountain plans to mass-produce his boat ladder.

    He created his invention at a workshop called TechShop. Mr. Mountain says, “I think it encourages innovation. I think people who probably have had ideas rolling around in the back of their minds for years but have never had the opportunity to actually put them into production or even experiment with them would find this place wonderful. Members of TechShop use high-tech equipment to develop and produce ideas they have for inventions.” Isabella Musachio manages a TechShop in Arlington, Virginia. She says the shop has many different kinds of equipment.

    “TechShop is a do-it-yourself maker space. So when you come in we have all these different areas of the shop, and we have a metal shop, wood shop, lasers, 3D printers, electronics. I mean, we have so many different areas and we have all the equipment that is availahle to anybody above the age of 12.”

    Membership costs for TechShop start at just over $ 100 per month. Members are able to use costly machines including 3D modeling tools and laser cutters. Isabella Musachio says TechShop helps its members build their dreams.

    “Our motto is ‘build your dreams here’ because you can really come in with just an idea, and then with the help of TechShop make that leap from an idea to building your project o, your prototype or even your business.”

    Jim Newton is the founder of TechShop. He first introduced the idea for the technology workshops at an arts and sciences event called Maker Faire in San Mateo, California in 2006. His idea attracted hundreds of members during that event, Now, there are eight TechShop locations in the U. S. In all, there are more than 6,000 members. Two more-TechShop locations in the cities of St. Louis and Look Angeles will be set up.

    While drunken driving may be on the decline, traffic safety experts remain puzzled over how to deal with another alcohol related danger: drunken pedestrians(行人).

    Pedestrians struck and killed by cars often are extremely drunk. In fact, they are intoxicated(喝醉的) 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（迷惑不解） about how to prevent disasters.

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

    A. Traffic Safety.

    B. Drunken Drivers.

    C. Drunken Pedestrian Accidents.

    D. A Severe Highway Safety Problem.

    2.Among the causes of walkers’ accidents, the most serious problem is ________.

    A. long delays in traffic signals that may make people cross streets ignoring traffic rules

    B. the alcohol level in their blood which is too high.

    C. a lack of adult keeping eyes on many children involved in accidents

    D. former drunken drivers whose licenses are not allowed to use for a time

    3.According to recent federal data, drunken drivers with an over 0.10 blood alcohol level in deadly accidents ____.

    A. are 15 percent less than drunken adult walkers with the same level

    B. are 2500 a year in US traffic accidents

    C. are at least 7000 in US traffic accidents

    D. make up one seventh of highway accidents

    4.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
