Which of the following is true about drones?
A.It is under proper supervision.
B.It has multiple purposes.
C.It is opposed by people.
D.It has no security problem.

[单选题]The TTL field was originally designed to hold a time stamp, which was decremented by each visited router. The datagram was ( ) when the value became zero. However, for this scheme, all the machines must have synchronized clocks and must know how long it takes for a datagram to go from one machine to another. Today, this field is used mostly to control the ( ) number of hops (routers) visited by the datagram. When a source host sends the datagram, it ( ) a number in this field. Each router that processes the datagram decrements this number by 1. If this value, after being decremented, is zero, the router discards the datagram.This field is needed because routing tables in the Internet can become corrupted.A datagram may travel between two or more routers for a long time without ever getting delivered to the (请作答此空).This field limits the ( ) of a datagram.
A.switch
B.router
C.source host
D.destination host

[单选题]Text 2 An old saying has it that half of all advertising budgets are wasted-the trouble is,no one knows which half.In the internet age,at least in theory,this fraction can be much reduced.By watching what people search for,click on and say online,companies can aim“behavioural”ads at those most likely to buy.In the past couple of weeks a quarrel has illustrated the value to advertisers of such fine-grained information:Should advertisers assume that people are happy to be tracked and sent behavioural ads?Or should they have explicit permission?In December 2010 America's Federal Trade Cornmission（FT C）proposed adding a"do not track"（DNT）option to internet browsers,so that users could tell adwertisers that they did not want to be followed.Microsoft's Internet Explorer and Apple's Safari both offer DNT;Google's Chrome is due to do so this year.In February the FTC and Digltal Adwertising Alliance（DA A）agreed that the industry would get cracking on responging to DNT requests.On May 31st Microsoft Set off the row:It said that Internet Explorer 10,the version due to appear windows 8,would have DNT as a default.It is not yet clear how advertisers will respond.Geting a DNT signal does not oblige anyone to stop tracking,although some companies have promised to do so.Unable to tell whether someone really objects to behavioural ads or whether they are sticking with Microsoft’s default,some may ignore a DNT signal and press on anyway.Also unclear is why Microsoft has gone it alone.Atter all,it has an ad business too,which it says will comply with DNT requests,though it is still working out how.If it is trying to upset Google,which relies almost wholly on default will become the norm.DNT does not seem an obviously huge selling point for windows 8-though the firm has compared some of its other products favourably with Google's on that count before.Brendon Lynch,Microsoft's chief privacy officer,bloggde:"we believe consumers should have more control."Could it really be that simple?29.which of the following is ture according to Paragraph.6?
A.DNT may not serve its intended purpose
B.Advertisers are willing to implement DNT
C.DNT is losing its popularity among consumers
D.Advertisers are obliged to offer behavioural ads

[单选题]Text 3 At first glance the patriarchy appears to be thriving.More than 90%of presidents and prime ministers are male,as are nearly all big corporate bosses.Men dominate finance,technology,films,sports,music and even stand-up comedy.In much of the world they still enjoy social and legal privileges simply because they have a Y chromosome.So it might seem odd to worry about the plight of men.Yet there is plenty of cause for concern.Men cluster at the bottom as well as the top.They are far more likely than women to be jailed,estranged from their children,or to kill themselves.They eam fewer university degrees than women.Boys in the developed world are 50%more likely to flunk basic maths,reading and science entirely.What can be done?Part of the solution lies in a change in cultural attitudes.Over the past generation,middte-class men have leamed that they need to help with child care,and have changed their behaviour.Working-class men need to catch up.Women have learned that they can be SUfgeons and physicists without losing their femininity.Men need to understand that traditional manual jobs arc not coming back,and that they can be nurses or hairdressers without losing their masculinity.Policymakers also need to lend a hand,because foolish laws are making the problem worse.America reduces the supply of marriageable men by locking up millions of young males for non-violent offences and then making it hard for them to find work when they get out（in Georgia,for example,felons are barred from feeding pigs,fighting fires or working in funeral homes）.A number of rich countries discourage poor people from marrying or cohabiting by cutting their benefits ifthey do.More generally,schools need to become more boy-friendly.They should recognise that boys like to rush around more than girls do:it's better to give them lots of organised sports and energy-eating games than to dose them with Ritalin or tell them off for fidgeting.They need to provide more male role models:employing more male teachers in primary schools will both supply boys with a male to whom they can relate and demonstrate that men can be teachers as well as firefighters.The growing equality of the sexes is one of the biggest achievements of the post-war era:people have greater opportunities than ever before to achieve their ambitions regardless of their gender.But some men have failed to cope with this new world.It is time to give them a hand.

A.Male-Would Be a Final Say in Business
B.Gender Inequality-a Thomy Question to Solve

[单选题]Text 4 A US drug company has increased the price of an acne cream by more than 3,900%to$9,561 in less than 18 months in the latest example of drug"price cheating",which has enraged the American public and become a central topic of debate in the presidential election campaign.Novum Pharma,a recently formed privately held Chicago-based company,bought the rights to drug Aloquin in May 2015.The 60g cream,which contains two cheap ingredients,was sold by its previous owner,Primus Pharmaceuticals,for$241.50.Nowm almost immediately increased the price by l,100%,and hiked the price higher still in January 2016.Figures seen by the Financial 77mes show the company increased the price a third time last week to take the cost to$9,561.So-called"price cheating",in which companies buy the rights to older drugs and then vastly increase their cost,has provoked outrage across the country and led to calls for reform of the US healthcare system.Earlier this month,Hillary Clinton claimed"It's time to move beyond talking about these price hikes and start acting to address them.AlI Americans deserve full access to the medications they need-without being burdened by excessive,unjustified costs."Clinton said she would change the law to allow the"emergency importation"of safe altemative treatments from abroad.Aloquin contains two cheap active ingredients:a decades-old antibiotic,iodoquinol,and an extract from the aloe vera plant.Iodoquinol can be bought for as little as$30 a tube and aloe vera cream costs a few dollars.The drug is labelled as"possibly effective",as the US Food and Drug Administration has stated that there is only limited evidence that the drug is effective.Novum has also drastically increased the price of its other two skin creams,Alcortin A and Novacort.The drugs are prescription only,with the cost being mostly covered by health insurance or government assistance.In instances when the full cost of the treatment isn't covered by insurance,Novum provides coupons to reduce the proportion that patients have to pay,while collecting the rest from the health plan.The company,which is privately held and does not publish figures on sales or profits,did not reply to requests for comment.A spokesman told the public that the firm was founded by"a group oflike-minded investors who believe in the firm's focus ofproviding therapeutic innovations that are affordable for patients".The quotation of Clinton indicates that——
A.emergency alternative drugs should be imported
B.Americans should decide the price of medicines
C.we should know the address ofthe medicine companies
D.prices ofAmerican drugs are too high to afford
