study.The University of Melbourne study shows that people who use the Internet for their own reasons at work are about 9 percent more productive than those who do not.Study author Brent Coker said,“Surfing the Internet at times helps increase an employees attention.”“People need to relax for a bit to get back their attention,”Coker said on the universitys website.“Having a short break,such as a quick surfing of the Internet,helps the mind to rest itself,leading to a higher total Internet attention for a days work,and as a result,increases productivity(生产效率),”he said.According to the study of 300 workers,70 percent of people who use the Internet at work surf the Internet for their own reasons during office hours.Among the most popular surfing activities are searching for information about products,reading online news,playing online games and watching videos.“Firms spend a lot of money on software toblocktheir employees from watching videos,using social networking sites or shopping online,”said Coker.“Thats not always a good idea.”However,Coker said the study looked at people who surfed the Internet in moderation(适度),or were on the Internet for less than 20 percent of their total time in the office.“Those who spend too much time surfing the Internet will have a lower productivity than those without.”he said.4.What does the University of Melbourne study

have managed to extract a gene from a preserved sample of a Tasmanian tiger and make it active.Thebreakthroughhas left them dreaming that one day they will be able to recreate the animal,which died out more than 70 years ago.And if it can be done with the Tasmanian tiger,it may also be possible to resurrect(复活)creatures that have been extinct for far longer.“There used to be a time when extinction meant forever,but no more,”said Professor Mike Archer.“We are now able to seriously challenge whether those animals that have gone for ever.What has been achieved is a very important step in bringing back those animals that are extinct.And while I think that technically it is still pretty difficult at the moment,we can now see the possibilities.Im personally convinced that the Tasmanian tiger will be brought back to life in my lifetime.”The breakthrough came after nine years of experiments by scientists at the University of Melbourne,who extracted a gene from one of several tigers preserved in alcohol in a Melbourne museum.They removed the equivalent gene from a mouse embryo implanted the tiger gene and then watched as the mouse continued to grow normally,suggesting the tiger gene had been activated.Team leader Dr.Andrew Pask said it was the first time DNA from an extinct species had been used to“induce(引起)a functional response in another living organism”.However,the animals entire gene structure would have to be revived in the same way to even begin the possibility of bringing the Tasmanian tiger back from the dead.Mick Mooney,a wildlife officer ofthe Tasmanian Government,was worried that such developments could encourage peoples indifference to the protection of endangered species.“If people think that we can bring animals back to life after theyve gone,they will start saying that there is nothing to worry about because we can fix it up later.”8.What does the underlined word“breakthrough”in the l paragraph refer to?A.Scientists have recreated new animals.B.Scientists have resurrected endangered animal.C.It has turned out that some creatures would not go extinct.D.A tiger gene has been extracted successfully and activated.9.Scientists are

earth again C.humans have come closer in reconnecting extinct animals D.reconnecting extinct animals is impossible 11.We can learn from Mick Mooncys words that_.A.he thought it unnecessary to worry about endangered animals B.his opinion is in contrast with that of the Tasmanian Government C.he thought people should be encouraged to protect endangered animals D.he is concerned that bringing extinct animals back to life may have a negative effect D The year 2020 will mark the beginning of the decade of the yold,or the“young old”,as the Japanese call people aged between 65 and 75.The traditional retirement age is 65.One might therefore expect peak retirement.By continuing to work,and staying socially engaged,the yold will change the world,as they have done several times before at different stages of their lives.The yold are more numerous,healthier and wealthier than previous generations of seniors.The yold are busier,too.In short,the yold are not just any group of old people.They are challenging the traditional expectations of the retired as people who wear slippers and look after the grandchildren.That will influence consumer,service and financial markets.The over-60s are one of the fastest-growing groups of customers of the airline business.The yold are vital to the tourism industry because they spend much more,when taking a foreign holiday,than younger adults.But for all this to happen,three big things will have to change,under pressure from the yold themselves.The most important is public attitudes towards older people,and in particular the expectation that the old ought to be putting their feet up and quietly retiring into the background.Then,government policies will have to change,too.The retirement age in many rich countries is still below the age to which many people want to work.The effective retirement age(the age at which people actually leave the workforce)is usually even lower.Third,higher numbers of healthy yold people will require drastic changes in health spending.Most diseases of ageing are bestmetwith prevention and lifestyle changes.But only about 2%3%of most countries health-care spending goes on prevention.That will have to rise,because although the yold will constitute a bulge of comparative health and activity over the next decade,by 2030 they will hit 75 and enter a long period of decline for which few rich countries are ready.12.What kind of people are the yold exactly?A.They are workaholics.B.They are full of energy.C.They enjoy being focused on.D.They like staying socially engaged.13.Why do the yold contribute to tourist industry?A.They like traveling more.B.They have more money.C.They consume more on travel.D.They have much free time.14.Whats the authors attitude toward health-care spending on prevention?A.Unsatisfied.B.Subjective.C.Neutral.D.Active.15.What does the underlined word“met”in the fourth paragraph mean?A.dealt with B.come across C.satisfied D.experienced.第二节（共 5 小题；每小题 2 分，满分
