问题     Everyone knows that the first rule of driving is never taking your eyes off the road. Teen drivers【C1】________being careful, but they tend to start multitasking after just a few months behind the wheel, according to research published Tuesday. And【C2】________older drivers can handle eating or talking to passengers, which【C3】________up the new drivers, dialing a cell phone increased the risk of accidents among young and【C4】________drivers alike.
    This isn’t great news, since it’s well【C5】________that distracted driving is a leading cause of accidents among all drivers.
    It makes sense that young drivers will start testing their limits after a few months behind the wheel, according to Bruce Simons-Morton, a behavioral scientist. "You increase the difficulty of a task until you make an【C6】________," Simons-Morton says. "It seems like a very natural thing but still it’s very【C7】________, because good driving ability and safety judgment develops【C8】________a very long period of time."
    Within six months of getting their licenses, young drivers in this study -started texting, eating and【C9】________the radio while driving as much as their more skilled【C10】________. But it takes thousands of hours of【C11】________to get good at driving, according to Simons-Morton. That disconnect may help【C12】________the high accident rates among teenage drivers.
    The researchers compared data from two small studies—one tracked 42【C13】________licensed young drivers and the other looked at 100 drivers with more experience.
    All the participants had sensors and cameras【C14】________in  their  cars.  The  researchers  used  the  sensors  to track when  drivers  got into  accidents  or  close  calls. The videos  were  then  used to  see  what  the  drivers were doing just before the accidents【C15】________.
    Because  the  researchers  wanted  to  focus  on  the【C16】________of  distracted  driving,  they【C17】________crashes caused  by  drunk  driving  and  ones  that  were  clearly caused by other drivers.
    Since the number of people in this study was small, Simons-Morton says the results will have to be【C18】________by other research. A couple of bigger studies already【C19】________the works, might make things clearer. But Simons-Morton says this is the first totally【C20】________look at teen driver distraction.
【C7】
选项 A、safe
B、troublesome
C、dangerous
D、confusing
答案C
解析 but still表示语义转折，前面的a very natural thing表达肯定意义，所以本空格需填入含否定意义的形容词。根据常识可知，在青少年开车时不断地增加任务的难度(increase the difficulty of a task)是很危险的，故C项dangerous“危险的”。A项safe“安全的”，开车时增加任务难度，肯定不安全。B项troublesome表示“麻烦的；讨厌的”。D项confusing表示“令人困惑的”，而下句所解释的原因是“需培养良好的驾驶能力和安全性判断”，这两项的语义均不通顺。
