未知题型 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 isnt great news, since its 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 its 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.【C1】A．start overB．start forC．start offD．come off

未知题型 The highest anxiety moment in the holiday season must be the moment just before your loved ones unwrap their gifts. The ribbon comes untied, the paper falls to the floor—what will their expression be?【C1】______out the right gift can be very difficult, and we can easily make mistakes. Before【C2】______a gift, we all ask ourselves two questions: How much to spend and what to get.【C3】______both questions are complex, the more complex one by far is what to get. We may not know the exact【C4】______of the other person;【C5】______we know what kind of gift they would absolutely love, we might still not know the exact color, size, etc.【C6】______these risks, giving an ill-suited gift risks showing the other person exactly how little we really know them. And from there the path to a【C7】______relationship is short The risk of giving the wrong thing is【C8】______gift givers often end up giving consumables such as wine and chocolate. After all, these are unlikely to be the 'wrong' gift for anyone. But theres a【C9】______: These safe gifts are not very 'gifty' and are unlikely to strengthen our relationship with the recipient【C10】______, when we give jewelry, art, or furniture, we take a risk that the other person will not like the【C11】______. But these risky gifts are more 'gifty' and, if they are successful, will【C12】______their goal of strengthening the social【C13】______between the person giving the gift and the person【C14】______it. So how much risk do most gift givers take? Not surprisingly, the majority of givers dont risk giving more risky gifts. But were they right in playing it【C15】______? In short: They were not. A research showed that, in general, gift givers dont【C16】______how much others will enjoy their gift.【C17】______, gift receivers preferred the riskier gift and wished that gift givers took more【C18】______. So perhaps this holiday season we should put an extra effort into gift giving. Lets throw caution to the winds,【C19】______the wine, chocolates, and gift certificates and give real gifts. The biggest risk is being【C20】______.【C1】A．TurningB．TakingC．FiguringD．Drawing
