B.In 2012.C.In 2013. D.In 2014.65.Which is not TRUE according to the writer's opinion?A.We should analyze the reasons for running the red light comprehensively.B.Drivers should be encouraged to learn the driving awareness in developed countries.C.Those who run the red traffic lights should be punished blindly.D.People should be educated often to obey the traffic rules.八、补全对话(每小题2分,共10分)A:I think teenagers should be allowed to get a driver's license as soon as they pass the test. B:Maybe.________(66).A:Do you think teenagers should be allowed to work?B:Yes.But they can't work ________(67).They should be allowed to work only on weekends. A:Should teenagers be allowed to get their ears ________(68)?B:I don't like pierced ears,but I think teenagers should spend more time on their studies.
