Section A 26 Many European countries have been making the shift to electric vehicles and Germany has just stated that they plan to ban the sale of vehicles using gasoli
18、ne and diesel as fuel by 2030. The country is also planning to reduce its carbon footprint by 80-95% by 2050,【 C1】 _a shift to green energy in the country. Effectively, the ban will include the registration of new cars in the country as they will not allow any gasoline【 C2】 _vehicle to be registered
19、 after 2030. Part of the reason this ban is being discussed and【 C3】 _is because energy officials see that they will not reach their emissions goals by 2050 if they do not【 C4】_a large portion of vehicle emissions. The country is still【 C5】 _that it will meet its emissions goals, like reducing emiss
20、ions by 40% by 2020, but the【 C6】_of electric cars in the country has not occurred as fast as expected. Other efforts to increase the use of electric vehicles include plans to build over 1 million hybrid and electric car battery charging stations across the country. By 2030, Germany plans on having
21、over 6 million charging stations【 C7】 _. According to the International Business Times, electric car sales are expected to increase as Volkswagen is still recovering from its emissions scandal. There are【 C8】 _around 155,000 registered hybrid and electric vehicles on German roads, dwarfed by the 45
22、million gasoline and diesel cars driving there now. As countries continue setting goals of reducing emissions, greater steps need to be taken to have a【 C9】 _effect on the surrounding environment. While the efforts are certainly not【 C10】 _, the results of such bans will likely only start to be seen
23、 by generations down the line, bettering the world for the future. A)acceptance I)incidentally B)currently J)installed C)disrupting K)noticeable D)eliminate L)powered E)exhaust M)restoration F)futile N)skeptical G)hopeful O)sparking H)implemented 27 【 C1】 28 【 C2】 29 【 C3】 30 【 C4】 31 【 C5】 32 【 C6】
24、 33 【 C7】 34 【 C8】 35 【 C9】 36 【 C10】 Section B 36 Apples Stance Highlights a More Confrontational Tech Industry A The battle between Apple and law enforcement officials over unlocking a terrorists smartphone is the culmination of a slow turning of the tables between the technology industry and the
25、United States government. B After revelations by the former National Security Agency contractor Edward J. Snowden in 2013 that the government both cozied up to(讨好 )certain tech companies and hacked into others to gain access to private data on an enormous scale, tech giants began to recognize the Un
26、ited States government as a hostile actor. But if the confrontation has crystallized in this latest battle, it may already be heading toward a predictable conclusion: In the long run, the tech companies are destined to emerge victorious. C It may not seem that way at the moment. On the one side, you
27、 have the United States governments mighty legal and security apparatus fighting for data of the most sympathetic sort: the secrets buried in a dead mass murderers phone. The action stems from a federal court order issued on Tuesday requiring Apple to help the Federal Bureau of Investigation(FBI)to
28、unlock an iPhone used by one of the two attackers who killed 14 people in San Bernardino, California, in December. D In the other corner is the worlds most valuable company, whose chief executive, Timothy Cook, has said he will appeal the courts order. Apple argues that it is fighting to preserve a
29、principle that most of us who are addicted to our smartphones can defend: Weaken a single iPhone so that its contents can be viewed by the American government and you risk weakening all iPhones for any government intruder, anywhere. E There will probably be months of legal confrontation, and it is n
30、ot at all clear which side will prevail in court, nor in the battle for public opinion and legislative favor. Yet underlying all of this is a simple dynamic: Apple, Google, Facebook and other companies hold most of the cards in this confrontation. They have our data, and their businesses depend on t
31、he global publics collective belief that they will do everything they can to protect that data. F Any crack in that front could be fatal for tech companies that must operate worldwide. If Apple is forced to open up an iPhone for an American law enforcement investigation, what is to prevent it from d
32、oing so for a request from the Russians or the Iranians? If Apple is forced to write code that lets the FBI get into the Phone 5c used by Syed Rizwan Farook, the male attacker in the San Bernardino attack, who would be responsible if some hacker got hold of that code and broke into its other devices
33、? G Apples stance on these issues emerged post-Snowden, when the company started putting in place a series of technologies that, by default, make use of encryption(加密 )to limit access to peoples data. More than that, Appleand, in different ways, other tech companies, including Google, Facebook, Twit
34、ter and Microsofthave made their opposition to the governments claims a point of corporate pride. H Apples emerging global brand is privacy: it has staked its corporate reputation, not to mention the investment of considerable technical and financial resources, on limiting the sort of mass surveilla
35、nce that was uncovered by Mr. Snowden. So now, for many cases involving governmental intrusions into data, once-lonely privacy advocates find themselves fighting alongside the most powerful company in the world. I “A comparison point is in the 1990s battles over encryption,“ said Kurt Opsahl, genera
36、l counsel of the Electronic Frontier Foundation, a privacy watchdog group. “Then you had a few companies involved, but not one of the largest companies in the world coming out with a lengthy and impassioned post, like we saw yesterday from Timothy Cook. Its profile has really been raised. “ J Apple
37、and other tech companies hold another ace: the technical means to keep making their devices more and more inaccessible. Note that Apples public opposition to the governments request is itself a hindrance to mass government intrusion. And to get at the contents of a single iPhone, the government says
38、 it needs a court order and Apples help to write new code: in earlier versions of the iPhone, ones that were created before Apple found religion on(热衷于 )privacy, the FBI might have been able to break into the device by itself. K You can expect that noose(束缚 )to continue to tighten. Experts said that
39、 whether or not Apple loses this specific case, measures that it could put into place in the future will almost certainly be able to further limit the governments reach. L That is not to say that the outcome of the San Bernardino case is insignificant. As apple and several security experts have argu
40、ed, an order compelling Apple to write software that gives the FBI access to the iPhone in question would establish an unsettling precedent. The order essentially asks Apple to hack its own devices, and once it is in place, the precedent could be used to justify law enforcement efforts to get around
41、 encryption technologies in other investigations far removed from national security threats. M Once armed with a method for gaining access to iPhones, the government could ask to use it proactively(先发制人地 ), before a suspected terrorist attackleaving Apple in a bind as to whether to comply or risk an
42、 attack and suffer a public-relations nightmare. “This is a brand new move in the war against encryption,“ Mr. Opsahl said. “ We have had plenty of debates in Congress and the media over whether the government should have a backdoor, and this is an end run(迂回战术 )around thathere they come with an ord
43、er to create that backdoor. “ N Yet it is worth noting that even if Apple ultimately loses this case, it has plenty of technical means to close a backdoor over time. “ If they are anywhere near worth their salt as engineers, I bet they are rethinking their threat model as we speak,“ said Jonathan Zd
44、ziarski, a digital expert who studies the iPhone and its vulnerabilities. O One relatively simple fix, Mr. Zdziarski said, would be for Apple to modify future versions of the iPhone to require a user to enter a passcode before the phone will accept the sort of modified operating system that the FBI
45、wants Apple to create. That way, Apple could not unilaterally introduce a code that weakens the iPhonea user would have to consent to it. P “Nothing is 100 percent hacker-proof,“ Mr. Zdziarski said, but he pointed out that the judges order in this case required Apple to provide “ reasonable security
46、 assistance“ to unlock Mr. Farooks phone. If Apple alters the security model of future iPhones so that even its own engineers “reasonable assistance“ will not be able to crack a given device when compelled by the government, a precedent set in this case might lose its lasting force. In other words,
47、even if the FBI wins this case, in the long run, it loses. 37 It is a popular belief that tech companies are committed to protecting their customers private data. 38 The US government believes that its access to peoples iPhones could be used to prevent terrorist attacks. 39 A federal court asked App
48、le to help the FBI access data in a terrorists iPhone. 40 Privacy advocates now have Apple fighting alongside them against government access to personal data. 41 Snowden revealed that the American government had tried hard to access private data on a massive scale. 42 The FBI might have been able to
49、 access private data in earlier iPhones without Apples help. 43 After the Snowden incident, Apple made clear its position to counter government intrusion into personal data by means of encryption. 44 According to one digital expert, no iPhone can be entirely free from hacking. 45 Timothy Cooks long web post has helped enhance Apples image. 46 Apples CEO has decided to appeal the federal courts order to unlock a users iPhone.
