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 mto 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 quicklythin slice information reliably only after we ground such snap reactions inthick 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 arumals: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.The time needed in making decisions may ____.Avary according to the urgency of the situationBprove the complexity of our brain reactionCdepend on the importance of the assessmentDpredetermine the accuracy of our judgment

请阅读Passage l。完成第21—25小题。Passage 1It's one of our common beliefs that mice are afraid of cats. Scientists have long known that even if a mouse has never seen a cat before, it is still able to detect chemical signals released from it and run away in fear. This has always been thought to be something that is hard-wired into a mouse s brain.But now Wendy Ingram, a graduate student at the University of California, Berkeley, has challenged this common sense. She has found a way to"cure" mice of their inborn fear of cats by infecting them with a parasite, reported the science journal Nature.The parasite, called Toxoplasma gondii, might sound unfamiliar to you, but the shocking fact is that up to one-third of people around the world are infected by it. This parasite can cause different diseases among humans, especially pregnant women--it is linked to blindness and the death of unborn babies.However, the parasite's effects on mice are unique. Ingram and her team measured how mice reacted to a cat's urine(尿) before and after it was infected by the parasite. They noted that normal mice stayed far away from the urine while mice that were infected with the parasite walked freely around the test area.But that's not all. The parasite was found to be more powerful than originally thought—even after researchers cured the mice of the infection. They no longer reacted with fear to a cat's smell,which could indicate that the infection has caused a permanent change in mice's brains.Why does a parasite change a mouse's brain instead of making it sick like it does to humans?The answer lies in evolution."It's exciting scary to know how a parasite can manipulate a mouse's brain this way," Ingram said. But she also finds it inspiring."Typically if you have a bacterial infection, you go to a doctor and take antibiotics and the infection is cleared and you expect all the symptoms to also go away."She said, but this study has proven that wrong."This may have huge implications for infectious disease medicine."The passage is mainly about__________.查看材料A．mice' s inborn terror of catsB．the evolution of ToxoplasmaC．a new study about the effects of a parasite on miceD．a harmful parasite called Toxoplasma gondii

Despite the most pains-taking research， no one has yet found the answer， One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times， and this makes it easier for cold viruses to be passed on.No one has yet found a cure for the cold.There are drugs and pain suppressors such as aspirin， but all they do is relieve the symptoms.Which of the following does not agree with the passage?AThe Eskimos do not suffer from colds all the time.BColds are not caused by cold.CPeople suffer from colds just because they like to stay indoors.DA person rnay catch a cold by touching someone who already has one.
