    An Australian company, Smart Car Technologies, has developed a system that lets drivers know when they’re speeding. When the technology becomes commercially available, it could help lead-footed drivers avoid tickets and also save lives. The company that developed the product hopes to convince Australian government agencies to put the technology into use in their automobile fleets.
    The product, called Speed Alert, links real-time location data and speed obtained with the help of GPS to a database of posted speed limits stored in a driver’s PDA or programmable mobile phone. The setup of the product does not need to be hooked up to a car’s speedometer. In fact, it is entirely portable. It will also work with newer phones and PDAs that have built-in GPS receivers. If a driver exceeds the speed limit, the speed is shown and an alert sounds.
    Michael Paine, an Australian vehicle design engineer and traffic safety consultant, was hired to analyze the product. He told Live Science that his colleagues in the road safety field are “very enthusiastic” about what they’re now calling “intelligent speed alert.” Other research, according to Paine, shows that 40 percent of all traffic deaths involve speeding. There is also a potentially controversial future use: “Since the system is so portable, it would be easy to make it a requirement for teenage drivers to always use a speed alert device when driving,” Paine said. “The system even has the capability to record speeding violations, so parents can monitor their teenage drivers.”
    The product will soon go on sale in Sydney.

    1. 1.

      What’s the purpose of the new product?

      1. A.
        To inform us of the new car system.

        To introduce some improvement in cars.
      3. C.
        To limit certain drivers to safe driving.
      4. D.
        To popularize the built-in car system.
    2. 2.

      The second paragraph mainly talks about        .

      1. A.
        the project of the built-in product
      2. B.
        why the system becomes popular
      3. C.
        the functions of GPS in cars
      4. D.
        how the product is programmed
    3. 3.

      Which of the following is true of Speed Alert according to Michael Paine?

      1. A.
        Most of the traffic deaths can be avoided.
      2. B.
        Speeding violations can be easily found out.
      3. C.
        The system will excite some teenage drivers.
      4. D.
        The product will not be available for adults.
    4. 4.

      What can be the best title of the passage?

      1. A.
        Speed Alert and Its Future Use.
      2. B.
        Progress in Car-making Science.
      3. C.
        Warning for Adventurous Drivers.
      4. D.
        New In-Car Device against Speeding.

    If you boss asks you to work in Moscow this year, he’d better offer you more money to do so — or even double that depending on where you live now. That’s because Moscow has just been found to be the world’s most expensive city for the second year in a row by Mercer Human Resources Consulting.

           Using the cost of living in New York as a base, Mercer determined Moscow is 34.4 percent more expensive including the cost of housing, transportation, food, clothing, household goods and entertainment(娱乐).

           A two-bedroom flat in Moscow now costs $4,000 a month; a CD $24.83, and an international newspaper $6.30, according to Mercer. By comparison, a fast food meal with a hamburger(汉堡包) is a steal at $4.80.

           London takes the No.2 place, up from No.5 a year ago, thanks to higher cost of housing and a stronger British pound relative to the dollar. Mercer estimates(估算) London is 26 percent more expensive than New York these days. Following London closely are Seoul and Tokyo, both of which are 22 percent more expensive than New York, while No.5 Hong Kong is 19 percent more costly.

           Among North American cities, New York and Los Angeles are the most expensive and are the only two listed in the top 50 of the world’s most expensive cities. But both have fallen since last year’s study — New York came in 15th, down from 10th place, while Los Angeles fell to 42nd from 29th place a year ago. San Francisco came in a distant third at No. 54, down 20 places from a year earlier.

           Toronto, meanwhile, is Canada’s most expensive city but fell 35 places to take 82nd place worldwide. In Australia, Sydney is the priciest place to live in and No. 21 worldwide.

    What do the underlined words “a steal” in Paragraph 3 mean?

       A. an act of stealing                      B. something delicious

       C. something very cheap                D. an act of buying

    London has become the second most expensive city because of ______.

       A. the high cost of clothing            B. the stronger pound against the dollar

       C. its expensive transportation        D. the high prices of fast food meals

    Which city is the third most expensive on the list?

       A. Tokyo.         B. Hong Kong.             C. Moscow.                  D. Sydney.

    Which city has dropped most on the list in North America?

       A. New York.   B. Los Angeles.             C. San Francisco.   D. Toronto.

    An Australian researcher is urging parents to load up their teenager’s backpack and make them walk to school.

    Professor Leon Straker says students who walk or cycle to school are less likely to have back and neck pain. But the study of 1,202 Western Australian 14­year­old found that 72% of students travelled to school by car or bus. Straker says the study suggests walking or cycling while carrying a schoolbag helps improve trunk (躯干) and spinal (脊柱的) muscle strength.

    This helps reduce back pain because greater muscle strength improves support for the back during load carrying .Despite advocating that parents get their children moving，Straker warns bag load should not exceed (超过) 15% of body weight.

    Straker says the study also stresses that neck pain is as common as back pain among young teenagers. This is an area that has been largely ignored，he says，but can be an important indicator of neck pain into adulthood.

    For the study，students were asked a series of questions such as how long they carried their bags for，how they carried their schoolbags，the method of travel，and their perceptions(感觉) about the bag’s weight.

    Straker says about half of all participants experienced back and neck pain，with slightly more females reporting neck pain. However，the gender (性别) difference may also be due to the fact that females have lower pain tolerance.

    Studies from the 1980s found carrying a bag over one shoulder was most common among teenagers. However in this study 85% of participants carried their bag over both shoulders.

    Straker believes the change has been driven partly through education campaigns，but also by increasing fashion status of backpacks and improved design.

    1.In the opinion of Leon Straker，parents should________.

    A．reduce the load of their children’s schoolbags

    B．put more books in their children’s schoolbags

    C．get their children’s schoolbags ready for school

    D．ask their children to walk to school carrying schoolbags

    2.If a child weighs 40 kilograms，the weight of his schoolbag should be________.

    A．no more than 15 kg

    B．less than 6 kg

    C．as heavy as 9 kg

    D．more than 6 kg

    3.We can learn from the passage that________.

    A．most of the students in Australia walk to school

    B．neck pain is uncommon among young teenagers

    C．walking while carrying a backpack helps reduce back pain

    D．males are more likely to experience back pain than females

    4.According to the passage，what change has taken place since the 1980s?

    A．How students carry their schoolbags.

    B．How heavy students’ schoolbags are.

    C．How students go to school every day.

    D．How long students carry their schoolbags for.

    The 16-year-old girl Jessica Watson is said to be the youngest person to sail non-stop alone around the world. But her record has been questioned because someone thought that she has not sailed far enough. She will also not be recognized by the World Speed Sailing Record Council, as it was too dangerous for someone under 18 years old.

    Ms Watson sailed into Sydney port on Saturday, seven months after leaving on a hard voyage. Family, friends and Australian Prime Minister Kevin Rudd have gathered to greet her. Thousands of well-wishers waited at the port and watched from boats as Ms Watson sailed her pink, 10m boat over the finishing line. Many more Australians watched the event broadcast live on television. Watson said she was just an “ordinary girl who believed in her dream”.

    Ms Watson left Sydney on 18 October, despite that some people disagreed to her plan. Watson traveled northeast through the South Pacific and across the equator (赤道), south to Cape Horn at the tip of South America, across the Atlantic Ocean to South Africa, through the Indian Ocean and around southern Australia. The route took her through some of the world’s most changeful waters, and she battled through huge storms and suffered seven accidents of her boat.

    People around the world have followed Ms Watson’s adventures on her blog, which she has daily updated (更新). On her blog, she wrote down beautiful sunrise over seas, the excitement of meeting a blue whale and the bright, terrible sight of a shooting star flying across the night sky above her boat. Ms Watson has reportedly sold her story to a news company for $700,000. She is planning to write a book on her experience.

    1.Which of the following oceans didn’t Ms Watson cross through in her voyage?

    A. The Pacific Ocean.                B. The Arctic Ocean.

    C. The Indian Ocean.                 D. The Atlantic Ocean.

    2.Ms Watson’s voyage will NOT be considered an official world record mainly because __________.

    A. no one can prove that her route was dangerous enough

    B. she hasn’t applied for the record

    C. teenagers are not encouraged to take such a dangerous adventure

    D. girls are not allowed to take part in the dangerous sports

    3.We can make a conclusion from this passage that Watson __________.

    A. would make another voyage for money

    B. made the world round voyage for money

    C. had no way to communicate with others during the voyage.

    D. is so confident and brave that she could overcome troubles on her own

    4. All the following can be inferred from this passage EXCEPT that __________.

    A. her book about her voyage is a best seller

    B. people in Australia had much interest in her voyage

    C. she spent more than 200 days alone at sea

    D. people have different attitudes towards her voyage
