Passage 1 Traffic lights are crucial tools for regulating traffic flow. They are not, however, perfect. Drivers exchange the gridlock that would happen at unmanaged junctions for a pattern of stop-go movement that can still be frustrating, and which burns more fuel than a smooth passage would. Creating such a smooth passage means adjusting a vehicle′s speed so that it always arrives at the lights when they are green. That is theoretically possible, but practically hard. Roadside signs wired to traffic lights may help, but they have not been widely deployed. Now scientists have an idea that could make the process cheaper and more effective. Instead of a hardwired network of signs, they propose to use mobile-phone apps. For a driver to benefit, he must load a special software, dubbed SignalGuru, into his phone and then mount it on a special bracket attached to the inside of his car′s windscreen, with the camera lens pointing forwards. SignalGuru is designed to detect traffic lights and track their status as red,amber or green. It broadcasts this information to other phones in the area that are fitted with the same software, and--if there are enough of them--the phones thus each know the status of most of the lights around town. Using this information, SignalGuru is able to calculate the traffic-light schedule for the region and suggest the speed at which a driver should travel in order to avoid running into red lights. Tests in Cambridge, Massachusetts, where five drivers were asked to follow the same route for three hours, and in Singapore, where eight drivers were asked to follow one of two routes for 30 minutes, revealed that SignalGuru was capable of predicting traffic-light activity with an accuracy of 98.2% and 96.3% respectively, in the two cities. This was particularly impressive because in Cambridge the lights shifted, roughly half-way through the test, from their off-peak schedule to their afternoon-traffic schedule, while in Singapore lights are adaptive, using detectors embedded under the road to determine how much traffic is around and thus when a signal should change. Fuel consumption fell, too--by about 20%. SignalGuru thus reduces both frustration and fuel use, and makes commuting a slightly less horrible experience. What did tests in Cambridge and Singapore reveal?
A.SignalGuru can detect the status of traffic lights with accuracy.B.Traffic lights in Cambridge work better than those in Singapore.C.Drivers in Singapore follow traffic rules better than those in Cambridge.D.Traffic lights in Cambridge are more adaptive in off-peak hour.

Passage 2 Scientists have found that although we are prone to snap overreactions, if we take a moment and think about how we are likely to react, we can reduce or even eliminate the negative effects of our quick, hard-wired responses. Snap decisions can be important defense mechanisms; if we are judging whether someone is dangerous, our brains and bodies are hard-wired to react very quickly, within milliseconds. But we need more time to assess other factors. To accurately tell whether someone is sociable, studies show, we need at least a minute, preferably five. It takes a while to judge complex aspects of personality, like neuroticism or open-mindedness. But snap decisions in reaction to rapid stimuli aren′t exclusive to the interpersonal realm. Psychologists at the University of Toronto found that viewing a fast-food logo for just a few milliseconds primes us to read 20 percent faster, even though reading has little to do with eating. We unconsciously associate fast food with speed and impatience and carry those impulses into whatever else we′re doing. Subjects exposed to fast-food flashes also tend to think a musical piece lasts too long. Yet we can reverse such influences. If we know we will overreact to consumer products or housing options when we see a happy face (one reason good sales representatives and real estate agents are always smiling), we can take a moment before buying. If we know female job screeners are more likely to reject attractive female applicants, we can help screeners understand their biases--or hire outside screeners. John Gottman, the marriage expert, explains that we quickly "thin slice" information reliably only after we ground such snap reactions in"thick sliced" long-term study. When Dr. Gottman really wants to assess whether a couple will stay together, he invites them to his island retreat for a much longer evaluation: two days, not two seconds. Our ability to mute our hard-wired reactions by pausing is what differentiates us from animals:dogs can think about the future only intermittently or for a few minutes. But historically we have spent about 12 percent of our days contemplating the longer term. Although technology might change the way we react, it hasn′ t changed our nature. We still have the imaginative capacity to rise above temptation and reverse the high-speed trend. Our reaction to a fast-food logo shows that snap decisions__________.
A.can be associativeB.are not unconsciousC.can be dangerousD.are not impulsive
Which of the following does NOT belong to the ways of collecting information for formative assessment?
A.Learner portfolio.B.Testing.C.Classroom observation.D.Questionnaire survey.
According to a recent research, the old are more than twice as likely to have a positive attitude to life __________ the young.
