Do not sign your own name at the end of the letter. Use "Li Ming" instead. Do not write the address. (10 points)

At noon on May 4th the carbon-dioxide concentration in the atmosphere around the Mauna Loa Observatory in Hawaii hit 400 parts per million(ppm). The average for the day was 399. 73 and researchers at the observatory expect this figure, too, to exceed 400 in the next few days. The last time such values prevailed on Earth was in the Pliocene epoch(上新世)4m years ago, when jungles covered northern Canada. There have already been a few readings above 400 ppm elsewhere—those taken over the Arctic Ocean in May 2012, for example—but they were exceptional. Mauna Loa is the benchmark(标准)for CO 2 measurement because Hawaii is so far from large concentrations of humanity. The Arctic, by contrast, gets a lot of polluted air from Europe and North America. The concentration of CO 2 peaks in May, falls until October as plant growth in the northern hemisphere"s summer absorbs the gas, and then goes up again during winter and spring. This year the average reading for the whole month will probably also reach 400 ppm, according to Pieter Tans, who is in charge of monitoring at Mauna Loa, and the seasonally adjusted annual figure will reach 400 ppm in the spring of 2014 or 2015. Mauna Loa"s readings are one of the world"s longest-running measurement series. The first, made in March 1958, was 315 ppm. That means they have risen by a quarter in 55 years. In the early 1960s they were going up by 0. 7 ppm a year. The rate of increase is now 2. 1 ppm—three times as fast—reflecting the relentless rise in green-house-gas emissions. As a rule of thumb, CO 2 concentrations will have to be restricted to about 450 ppm if global warming is to be kept below 2 degrees. Because CO 2 stays in the atmosphere for decades, artificial emissions of the gas would have to be cut immediately, and then fall to zero by 2075, in order to achieve 450 ppm. There seems no chance of that. Emissions are still going up. At current rates, the Mauna Loa reading will rise above 450 ppm in 2037.

You are going to read a list of headings and a text. Choose the most suitable heading from the list[A]to[G]for each numbered paragraph (41-45). There are two extra subheadings which you do not need to use. Mark your answers on the ANSWER SHEET. (10 points)[A]Never say goodbye[B]Open up channels of communication[C]Weigh your options[D]Surprise them[E]Commitment[F]Make sacrifices[G]Plan get-togethersWe all hope that our friendships will be enduring and vibrant. We also hope that despite our differences in gender, interests and careers, we would stick together through the thick and thin of life. Here are five ways you can save your friendship despite the changes in both your lives:【R1】______You will have to come to the point where you have to decide if this friendship is important enough to make sacrifices, this will be the only way you can commit to the revival and survival of your friendship. You will also have to make sure if your friend is in it for the long haul too, because it takes two to tango. If the feelings are mutual, the effort will be equal. It will be futile if you work on saving this friendship and he or she could not give two pennies worth about it. 【R2】______Once you have decided that the two of you have climbed Mount Everest long enough together and that this friendship is without a doubt worth saving, then I suggest you have a heart-to-heart like there is no tomorrow. It is not impossible—it all depends on what you put in, both of you. It is fundamental that you put in the time and the effort; it is then that you will see this friendship flourish like never before. 【R3】______Why not spend a fun weekend away? Just the two of you, a bottle of wine and the open road (just do not do the drinking and the driving at the same time). Be creative and make sure you make some remarkable new memories, especially the ones that extend the dorm room and hallway ones. You have grown up and moved along with your life, so should your memories. 【R4】______There is nothing like finding a signed, sealed and delivered a package from your best friend at your front door. It brings a solid feeling of gratitude with the excitement and you know that this friendship is one that will endure all the storms, especially if the college friend lives abroad and had to pay a lot to get that package there at the right place and at the right time, for instance, your birthday. 【R5】______Once you are faithful to each other, you will have no problem in saving the friendship and allowing it to be a success. It will entail you sacrificing some things in your life, but if the friendship is worth it, it will not be a problem. It is also important to remember that no relationship is perfect; you will most likely have some downs following the ups.

The essential functions of the UN are to maintain international peace and security, to develop friendly relations among nations, to cooperate internationally in solving international economic, social, cultural and human problems, promoting respect for human rights, and fundamental freedoms, and to be a centre of coordinating the actions of nations in attaining these common ends. No country takes precedence over another in the UN. Each member's obligations and rights are the same. All must contribute to the peaceful settlement of international disputes, and members have pledged to refrain from the threat or use of force against other states. Though the UN has no right to intervene in any state's internal affairs, it tries to ensure that non-member states act according to its principles of peace and security. UN members must offer every assistance in an approved UN action and in no way assist states against which the UN is taking preventive or enforcement action.

What has been described as the largest ever ransomware attack—a cyber criminal scheme that locks up computer files until victims pay a ransom—holds the paradoxical distinction of being both an outrageous success (in terms of its blast radius) as well as an abject failure (in terms of its haul). The malicious software spread so far and wide, jammed up so many IT networks and generated so much panic and chaos that the wrongdoers effectively undid themselves. On May 12, the world awoke to the beginnings of hundreds of thousands of old Microsoft Windows based computers' seizing up as they subjected to a malicious software, appropriately called WannaCry. Within hours, the digital epidemic circled the globe like the Spanish flu, infecting machines running outdated operating systems in some 150 countries, spreading across numerous homes and corporate networks. The attack, which relied on powerful tools believed to have been developed by the NSA and leaked online in April by a group of hackers known as the Shadow Brokers, wormed its way through businesses, hospitals and governments, all of which found themselves suddenly locked out of their own systems. Researchers detected the wave quickly, and it wasn't long before they picked up on the criminals' self-defeating mistakes. The attackers failed to assign each victim a separate Bitcoin wallet , researchers noted, a critical error that meant they would not be able to easily track ransom payments. They neglected to automate the money collection in a way that would scale. And then there was the matter of the kill switch. No one is quite certain why the attackers coded a self-destruct button into their software, yet that's precisely what they did. Marcus Hutchins, a 22-year-old security researcher based in England who goes by MalwareTech, stumbled on the power plug largely by accident. After taking lunch on that Friday afternoon, he inspected the malware and noticed a specific web address encoded within. Curious, he registered the domain for less than $ 11. This simple act stopped the malware, killing the virus' ability to spread and buying time for organizations to upgrade their software and deploy protections.

America has seen a drop in crime rates that in earlier years would have been universally viewed as impossible. The overall crime rate has plummeted by 45% since peaking in 1991 and by 13% just since 2007—counterintuitively continuing to drop through the recession and sharp spike in unemployment. Since 1991, according to FBI data, the number of violent crimes has fallen 36% nationally and 64% in the nation"s largest cities. And in New York and Los Angeles, the nation"s two largest cities , it has fallen even further. Property crime has also become increasingly rare. Incredibly, in New York City, car thefts have plunged 94% in the past two decades. How is this possible? In the mid-1990s, few saw this decline coming, and many warned that crime would surge once again as teens of that era grew into young adults. Today, criminologists still differ on what has caused the nationwide turnaround in crime rates and why those dire predictions never came to pass. But crime-fighting technology, better policing, aging societies, growing urban populations and declining usage of hard drugs are widely cited. For many Americans, the drop in crime has resulted not only in a much higher quality of life but in a reduced economic burden as well. Safer cities generally mean stronger urban economies. In the same category of big surprises, teen-pregnancy rates have fallen to their lowest level in more than 30 years, according to the widely respected Guttmacher Institute. They have declined 51% from their 1990 peak, based on the latest available data, and the teenage birthrate is down 43% from that year"s level. Today, fewer teens are becoming pregnant and becoming mothers than at any point since reliable data has been collected by the National Center for Health Statistics. This is also true for women in the 20-to-24 age group. To put it mildly, there were very few predictions to this effect a generation ago. In addition, overall birthrates in the U. S. have turned up for the first time since 2007—including for children born to women in a college education—to just shy of 4 million.

Imagine a world in which there was suddenly no emotion—a world in which human beings could feel no love or happiness, no terror or hate. Try to imagine the consequences of such a transformation. People might not be able to stay alive: knowing neither joy nor pleasure, anxiety nor fear, they would be as likely to repeat acts that hurt them as acts that were beneficial. They could not learn: they could not benefit from experience because this emotionlessness would lack rewards and punishments. Society would soon disappear; people would be as likely to harm one another as to provide help and support. Human relationships would not exist; in a world without friends or enemies, there could be no marriage, affection among companions, bonds among members of groups; society's economic underpinnings would be destroyed; since earning $ 10 million would be no more pleasant than earning $ 10, there would be no incentive to work.

Big companies swallow little ones every day. So the【C1】______on March 25th by Yahoo (annual revenue, $5 billion) of Summly, a British start-up (annual revenue, zero), for a reported $30m would normally【C2】______merely a shrug of the shoulders and some muttering about the【C3】______economics of the internet. The deal is worth noting,【C4】______, for two reasons. One is that Summly"s founder, Nick d"Aloisio, is only 17: this summer he will be sitting his【C5】______like other teenagers. He invented an iPhone app to【C6】______articles in 300-400 characters, ideal for the smartphone-user wondering what he should【C7】______reading. Li Ka-shing, a Hong Kong telecoms tycoon, invested money in the【C8】______, having got wind of an early version of the app after tech blogs wrote about it, Mr d"Aloisio says. Famous actors, artists and entrepreneurs have also【C9】______in, taking the sum outsiders invested in Summly to $1.5m. Mr d"Aloisio says that he remained the largest shareholder. The second reason is that Summly is just the latest of half a dozen start-ups【C10】______by Yahoo in as many months. The internet company has also bought Stamped, Alike and Jybe, which built apps for personalized recommendations of,【C11】______other things, books, food and music; OnTheAir, a video-chat company; and Snip.it, which created an app for managing and sharing articles. Marissa Mayer, Yahoo"s boss since July, says she is【C12】______make the company a stronger force on smartphones and tablets.

An earthquake hit Kashmir on Oct. 8, 2005. It took some 75 000 lives,【C1】______ 130 000 and left nearly 3. 5 million without food, jobs or homes.【C2】______ overnight, scores of tent villages bloomed【C3】______ the region, tended by international aid organizations, military【C4】______ and aid groups working day and night to shelter the survivors before winter set【C5】______. Mercifully, the season was mild. But with the【C6】______ of spring, the refugees will be moved again. Camps that【C7】______ health care, food and shelter for 150 000 survivors have begun to close as they were【C8】______ intended to be permanent. For most of the refugees, the thought of going back brings【C9】______ emotions. The past six months have been difficult. Families of 10 many as【C10】______ people have had to shelter【C11】______ a single tent and share cookstoves and bathing【C12】______ with neighbors.

Peek through the inspection windows of the nearly 100 three-dimensional (3D) printers quietly making things at RedEye, a company based in Minnesota, and you can catch a glimpse of how factories will work in the future. It is not simply that the machines run day and night【C1】______by just a handful of technicians.【C2】______it is what they are making that shows how this revolutionary production process is【C3】______the manufacturing mainstream. 3D printers make things by building them up, a layer at a time,【C4】______a particular material, rather than【C5】______it by cutting, drilling or machining—which is why the process is also called additive manufacturing. There are many ways in which this can be done, and with only a【C6】______adjustment of software each item can be different,【C7】______the need for costly retooling of machines. This has made 3D printing a【C8】______way to make one-off items, especially prototype parts, mock-ups, small mechanical【C9】______and craft items. And that is about all that 3D printers are good for,【C10】______the doubters. Chief among them is Terry Gou, the boss of Foxconn. He thinks 3D printing is just "a trick" without any【C11】______value in the manufacture of real finished goods, and he has vowed to start spelling his name backwards if【C12】______wrong. Mr. Gou is right about one thing: additive manufacturing is not about to replace mass manufacturing.【C13】______the technology is improving, the finish and durability of some printed items can still【C14】______what producers require. And nor can 3D printers produce millions of【C15】______parts at low cost, as mass-production lines can.【C16】______3D printers have their【C17】______which is why they are starting to be used by some of the world"s biggest manufacturers, such as Airbus, Boeing, GE, Ford and Siemens. The market for 3D printers and【C18】______is small, but growing fast. Last year it was worth $2.2 billion worldwide, up 29% from 2011. As producers become more【C19】______with the technology, they are moving from prototypes to final【C20】______.

[A] Set a Good Example for Your Kids[B] Build Your Kids' Work Skills[C] Place Time Limits on Leisure Activities[D] Talk about the Future on a Regular Basis[E] Help Kids Develop Coping Strategies[F] Help Your Kids Figure Out Who They Are[G] Build Your Kids' Sense of Responsibility How can a Parent Help Mothers and fathers can do a lot to ensure a safe landing in early adulthood for their kids. Even if a job's starting salary seems too small to satisfy an emerging adult's need for rapid content, the transition from school to work can be less of a setback if the startup adult is ready for the move. Here are a few measures, drawn from my book Ready or Not, Here Life Comes, that parents can take to prevent what I can "work life unreadiness" : 【R1】______ You can start this process when they are 11 or 12. Periodically review their emerging strengths and weaknesses with them and work together on any shortcomings, like difficulty in communicating well or collaborating. Also, identify the kinds of interests they keep coming back to, as these offer clues to the careers that will fit them best. 【R2】______ Kids need a range of authentic role models—as opposed to members of their clique, pop stars and vaunted athletes. Have regular dinner table discussions about people the family knows and how they got where they are. Discuss the joys and downsides of your own career and encourage your kids to form some ideas about their own future. When asked what they want to do, they should be discouraged from saying "I have no idea" . They can change their minds 200 times, but having only a foggy view of the future is of little good. 【R3】______ Teachers are responsible for teaching kids how to learn, parents should be responsible for teaching them how to work. Assign responsibilities around the house and make sure homework deadlines are met. Encourage teenagers to take a part-time job. Kids need plenty of practice delaying gratification and deploying effective organizational skills, such as managing time and setting priorities. 【R4】______ Playing video games encourages immediate content. And hours of watching TV shows with canned laughter only teaches kids to process information in a passive way. At the same time, listening through earphones to the same monotonous bats for long stretches encourages kids to stay inside their bubble instead of pursuing other endeavors. All these activities can prevent the growth of important communication and thinking skills and make it difficult for kids to develop the kind of sustained concentration they will need for most jobs. 【R5】______ They should know how to deal with setbacks, stresses and feelings of inadequacy. They should also learn how to solve problems and resolve conflicts, ways to brainstorm and think critically. Discussions at home can help kids practice doing these things and help them apply these skills to everyday life situations. What about the son or daughter who is grown but seems to be struggling and wandering aimlessly through early adulthood? Parents still have a major role to play, but now it is more delicate. They have to be careful not to come across as disappointed in their child. They should exhibit strong interest and respect for whatever currently interests their fledging adult (as naive or ill-conceived as it may seem) have while becoming a partner in exploring options for the future. Most of all, these new adults must feel that they are respected and supported by a family that appreciates them.
