2、 second,or,more precisely,change to the unusual time of 7:59:60,according to .The addition of a leap second(闰秒),announced by the Paris Observatory,is to keep our clocks in time with the slowing of Earths rotation(旋转) and astronomical time as measured by the sun.Just one extra second could cause big

3、problems and affect the way computers and websites work,however.When the last leap second was added back in 2012,more than a few websites had some trouble.As reported by Phys.org,popular sites like the community website Reddit crashed when the leap second was added.For Reddit,the problem was eventua

4、lly found to be with a Linux system that got confused when it checked the network time and found an extra second.Speaking to Wired about the problem back in 2012,Linux creator Linus Torvalds commented:“Almost every time we have a leap second,we find something.Its really annoying,because its code(代码)

5、 that is almost never used,and thus not tested by users under their normal conditions.”Companies have had to think of their own solutions,and Googles “leap smear” may be the best-known example.As company engineer Christopher Pascoe explains in a blog post,companies usually try to fix the problem by

6、turning back the clocks by one second at the end of the day so that they play that second again.However,Pascoe believes this creates problems.He asked:“What happens?Does e-mail that comes in during that second get stored correctly?”Google has a solution:Cut the extra second into milliseconds and the

7、n put these tiny amounts of time into the system throughout the day.“This means that when it became time to add an extra second at midnight,”says Pascoe.“Our clocks have already taken this into account over the course of the day.”For many companies without Googles money,however,the leap second will

8、likely still cause some crashes.Dont worry,thoughat least it wont last long!语篇解读本文主要介绍了“闰秒”带来的影响及其解决方案。1Why do we need to add a leap second?AThe worlds atomic clocks are set to do so.BTo keep in time with the worlds computers.CTo keep atomic clocks in time with the slowing of Earths rotation.DTo rec

9、ord the changes to astronomical time.答案C解析细节理解题。根据文章第二段中“The addition of a leap second(闰秒),announced by the Paris Observatory,is to keep our clocks in time with the slowing of Earths rotation(旋转) and astronomical time as measured by the sun.”可知,闰秒是由于地球自转变慢引起的,为了与由太阳测量的天文时间一致而增加一秒,故选C。2What happened

10、to the website Reddit when the leap second was added in 2012?AIt crashed because of a virus attack.BIts network time added two extra seconds.CAll of the code in its Linux system went wrong.DOne of its software systems got confused and the site broke down.答案D解析细节理解题。根据第三段最后一句和第四段中“the problem was eve

16、make a choice between two appealing choices,according to a new study.The study builds on past research into a phenomenon known as “the Macbeth effect”It turns out that Shakespeare was really onto something when he imagined Lady Macbeth trying to clean her conscience(良心) by rubbing invisible bloodsta

17、ins from her hands.A few years ago,scientists asked people to describe a past wrong act.If people were then given a chance to clean their hands,they later expressed less guilt than people who hadnt cleaned.This finding fascinated WS.Lee,a researcher.“Anything from the past,any kind of negative emoti

18、onal experiences,might be washed away,” says Lee.He decided to test hand washings effect on one kind of bad feeling:the tension we feel after being forced to choose between two attractive choices,because picking one choice makes us feel that weve lost the other.People usually try to calm this inner

19、conflict by later exaggerating(夸大) the positive aspects of their choice.He had students rank 10 different music CDs.Then he offered students one CD as a gift.Some students then used liquid soap.Others only looked at the soap or sniffed(嗅) it.“Actually,you do not need water and soap,” says Lee.Later,

20、the students again had to rank all the music.People who didnt wash their hands had the normal responsethey scored their take-home CD higher,suggesting that they now saw it as even more attractive than before.But this wasnt true for the hand washers.They ranked the music about the same.“They feel no

21、need at all to justify the choice,” says Lee.But the implications of it just arent clear.Schwarz says its too soon to know whether people should head for a sink after making a tough choice.He says washing may help decision-makers by cleaning away mental disorder,but perhaps if they dont go through t

28、 Institute of Technology.Ellen Langer,a Harvard psychologist who studies how the mind influences the body,and her colleagues reviewed the scientific literature for evidence that a persons perception of their age might influence their health.They published their results in the journal PerspectivesonP

29、sychologicalScience.In one study that Langer led,47 women had their hair done.The women who thought their new hairdos(发型) made them look younger did look younger to objective observers,who were shown before-and-after pictures.The women who thought they looked younger also showed a drop in blood pres

30、sure.Another study involving 4,421 men found that those who became bald(秃顶) at a relatively young age were more likely to get cancer and heart disease than men who did not.Similarly,another study involving 2,017 men found that those who lost their hair early were more likely to develop heart disease

31、.“We believe that the feelings associated with being older than ones real age account for some of these health outcomes,” the researchers wrote.The researchers also described studies which found that women who had children later in life were more likely to be healthier and live longer than those who

32、 had children early,which they attributed to the fact that these mothers tend to spend more time with younger women.Similarly,people who marry younger partners tend to live longer than those who marry older partners,according to other studies.Taken together,the research supports the general mind-bod

33、y hypothesis(假说) that when a younger mind is prepared,a younger body can accompany it.While the mechanism(机制) remains unclear,the researchers figured that suggestions associated with aging can make one unconsciously or consciously aware of old age and set in motion a series of physiological processe

34、s that can have real effects on short-term and long-term health.语篇解读本文为说明文,题材为科普知识类。觉得自己更年轻的人更健康也活得更长。11The underlined word “perception” in Paragraph 2 means “”Aview BappearanceCinfluence Dcreation答案A解析词义猜测题。由第一段第一句中的“Youre as young as you feel”及第二段第一句中的“how the mind influences the body”可推测出答案。12Whi

40、genes.But the truth is that genes only make up 1 to 2 percent of our DNA,which caused scientists to believe that the rest of it is useless.Nevertheless,instead of doing nothing,junk DNA,as it is called,turned out to be playing an important part in our body.If genes are like light bulbs,then junk DNA

41、 acts as switches.They control which genes are used in a cell and how active they are.For example,they can determine whether a cell becomes a lung cell or a neuron(神经元)The study,published in the journal Nature on September 5,started in 2003,and 442 scientists from 30 labs around the world were invol

42、ved,according to Reuters.It is considered the biggest breakthrough in genomics(基因学) in a decade because it might help scientists find the cause of certain diseases.It has long been known that many complicated diseases,such as cancer,are caused by tiny changes in DNA.But now scientists realize that m

43、ost of the changes occur not in the genes themselves,but in the “junk” part of the DNA.They are able to keep track of how and why the switches change and then figure out new treatments and drugs.“Our former understanding of DNA was like getting a picture of Earth from space,”Eric Lander from the Bro

44、ad Institute,US,told TheNewYorkTimes.“You know the planet is there,but you cannot see exactly what its like on the surface.”But now with the new study result “you can follow the roads and see the traffic circulation.Thats exactly the same way we will use this data in cancer research,”explained Mark

45、Rubin from Weill Cornell Medical College in New York.16Which of the following would be the best title for the passage?ADNAThe Cause of CancerBWhat Is DNA?CA New Discovery for “Junk DNA”DA Misunderstanding of Genes答案C解析标题归纳题。本文主要介绍了垃圾DNA其实在我们的身体中也扮演着重要的角色,这是医学上的一个新发现,故选C。17What does the underlined ph

46、rase “get it right” in the first paragraph refer to?ADiscovering new types of DNA.BRecognizing the importance of junk DNA.CUnderstanding the role genes play in DNA.DTelling useful DNA from useless one.答案B解析词义猜测题。根据上文中的“多年前科学家对于垃圾DNA也犯了同样的错误”可推知,他们现在正在纠正,也就是认识到垃圾DNA的重要性。故选B。18The author explains how

47、different parts of DNA work by .aintroducing a general theorybmaking a metaphor(比喻)cgiving examplesddisplaying research dataAa,c Bb,cCa,d Dc,d答案B解析细节理解题。根据第三段最后一句“If genes are like light bulbs,then junk DNA acts as switches.”可知,作者使用比喻来解释DNA的作用;根据第四段内容可知,作者具体举出了例子,故选B。19The results of the study menti
