问题 There is no good place to have a car crash -- but some places are worse than others. In a foreign country, for instance,(1)to explain via cellphone that you are upside down in a ditch when you cannot speak the local language can fatally delay the arrival of the emergency services.    But an answer may be at hand. Researchers funded by the European Commission are beginning tests of a system called E-merge that(2)senses when a car has crashed and sends a text message telling emergency services in the local language that the accident has taken place.    The system was(3)by ERTICO, a transport research organization based in Brussels, Belgium. Cars are fitted with a cellphone-sized device attached(4)the underside of the dashboard which is activated by the same sensor that triggers the airbag in a crash. The device(5)a cellphone circuit, a GPS positioning unit and a microphone and loudspeaker.    It registers the severity of the crash by(6)the deceleration data from the airbag’s sensor. Using GPS information, it works out which ootmtry the Car is in, and from this it determines(7)which language to compose an alert message detailing precise location of the accident.    The device then automatically makes a call to the local emergency services(8). If the car’s occupants are conscious, they can communicate with the operator(9)the speaker and microphone.    E-merge also transmits the vehicles make, model, color and license number, and its heading when it crashed, which in rum indicates on which side of a multi-lane highway it ended up.’    This(10)the emergency services find the vehicle as soon as they arrive on the scene. "We can waste a large(11)time searching for an incident," says Jim Hammond, a (an)(12)in vehicle technology at the Association of Chief Police Officers in the UK. Tests will begin soon with police car fleets in the UK. Trials have already started in Germany, Sweden, Spain, the Netherlands and Italy.    In-car systems that summon the emergency services after a crash have(13)been fitted in some premium cars. ERTICO says that(14)EU states "are willing to fund the necessary infrastructure, E-merge could be working by 2008.    A study by French car maker Renault concluded that the system could save up to 6000 of the 40, 000 lives lost each year on Europe’s roads, and prevent a similar number of serious injuries.    The Renault study estimates that fitting E-merge to every car in Europe would eventually save around 150 billion per(15)in terms of reduced costs to health services and insurance companies, and fewer lost working days.

答案C
解析 备选项是同一单词的不同形态，因此判断该题考察语法结构。空格处所在的结构在句子中做主语，因此C是答案。不选择D是因为句子中主语部分的动作词和谓语部分的动作词之间没有强调“动作的先后关系”。
