        Most Americans are worried about new technology. They are concerned that machines, including robots, will take over work now done by humans. These findings come from a new report by the Pew Research Center of Washington D. C.

        About 75 percent of Americans questioned by Pew said automation will increase income inequality between the rich and the middle class and poor. And 64 percent of people expect automation to be so common in America that people will face difficulty finding things to do with their lives.

        Some of the concerns about technology come from a distrust about whether machines will always make the right decision. Many Americans believe humans have better judgement in dealing with. complex matters. One example is selecting a person for a job. Three-quarters of Americans said they would not want to apply for a job that uses a computer program to choose the most qualified person.

        “Most Americans want the government to limit automation. For example, 87 percent support a requirement that all driverless vehicles have a human in the driver's seat who can take control when an emergency occurs. And 85 percent want to limit machines to mostly doing jobs that are dangerous or unhealthy for humans. And only 25 percent expect more jobs to come from automation,” Pew said.

        Mark Zuckerberg, the co-founder of Facebook, spoke last May to graduating seniors from Harvard University in Massachusetts. His talk centered on the uncertain future facing young people. “Our generation will have to deal with tens of millions of jobs replaced by automation like self-driving cars and trucks.” Zuckerherg told the graduates.

        Zuckerberg said young people had better launch(发起)projects that will bring both jobs and direct benefits to the people of the world. He said in his speech that 30000 people worked to put a man on the moon, and millions of people built the Hoover Dam as well as other great projects over the last 100 years.

    (1)What do many Americans think of technology according to paragraph 3?
    A . Useful. B . Effective. C . Dangerous. D . Undependable.
    【答案】
    (2)Why do Americans want a human in driverless vehicles?
    A . To test the new technology. B . To make a driver. C . To ensure personal safety. D . To entertain the passengers.
    【答案】
    (3)W hat did Zuckerberg encourage the students to do?
    A . Refuse self-driving vehicles. B . Create new job chances. C . Focus on small projects. D . Fight against robots.
    【答案】
    (4)Which of the following would be the best title for the text?
    A . New Technology Creates More Jobs B . New Technology Brings More Fairness C . Americans Worry Machines Will Take Jobs D . Robots Make Work Easy to Do for Workers

    "Over the years the unthinkable hasbecome thinkable and today we sense we are close to being able to alter humanheredity œ#)." These were the words of David Baltimore of the CaliforniaInstitute of Technology, on December 1st, when he opened a three-day meeting inWashington to discuss the morality and use of human gene editing. Dr Baltimoreis an old hand at these sorts of discussions, for he was also a participant inthe Asilomar conference, in 1975, which brought scientists together to discussa safe way of using the then-new tcchnology of recombinant DNA, and whoserecommendations influenced a generation of biotechnology researchers.

    Four decades on, the need for a similarsort of chin-wag has arisen. The InternationalSummit on Human Gene Editing has been held by the national scientific academiesof three countries — America, Britain and China. They are particularlyconcerned about whether gene editing should be used to make heritable changesto the human germ line, something Dr Baltimore described as a deep andtroubling question. Like those of Asilomar, the conclusions of this meetingwill not be binding. But the hope is that, again like Asilomar, a mixture ofcommon sense and peer pressure will create a world in which scientists aretrusted to regulate themselves, rather than having politicians and civilservants do it for them. The meeting is being held against a backdrop of rapidscientific advance, Since 2012 research into a new, easy-to-use editing tool calledCRISPR-Cas9 has blossomed. This technique involves a piece of RNA (a chemicalmessenger, which can be used to recognise a target section of DNA) and anenzyme (酶)called a nuclease that can snip unwanted genes out and paste new ones in.

    Public interest was aroused in April,when Chinese scientists announced they had edited genes in non-viable ( 无活力的) humanembryos, and again in November when British researchers said they hadsuccessfully treated a one-year-old girl who had leukaemia ( 白血病),using gene-edited T-cells. T-cells are part of the immune system that attack,among other things, tumour cells. The researchers altered T-cells from ahealthy donor to encourage them to recognise and kill the patient's cancer, tomake them immune to her leukaemia drug, and to ensure they did not attack herhealthy cells.

    In another recent development, a firmcalled Edit as Medicine, which is based in Cambridge, Massachusetts, has saidit hopes, in 2017, to start human clinical trials of CRISPR-Cas9 as a treatmentfor a rare genetic form of blindness known as Leber congenital amaurosis (伯氏先天性黑蒙).Though other companies are already testing gene-editing therapies, these employolder, clunkier forms of the technology that seem likely to have lesscommercial potential. Moreover, researchers at the Broad Institute, also inCambridge, said this week that they had made changes to CRISPR-Cas9 whichgreatly reduce the rate of editing errors — one of the main obstacles to thetechnique's medical use.

    On the subject of germ-line editing,Eric Lander, the Broad's head, told the meeting it would be useful only in rarecases and said it might be a good idea to "exercise caution? before makingpermanent changes to the gene pool. The need for caution is advice that mightalso be heeded by those pursuing work in animals other than people, and inplants — subjects not being covered by the summit.

            While clean energy is increasingly used in our daily life,global warning will continue for some decades after CO2 emissions(排放)peak. So even if emission were to begin decrease today,we would still face the challenge of adapting to climate. Here I will stress some smarter and more creative examples of climate adaptation.

         When it comes to adaptation,it is important to understand that climate change is a process. We are therefore not talking about adapting to a new standard,but to a constantly shifting set of conditions. This is why in part at least,the US National Climate Assessment says that:”there is no ‘one-size fit all' adaptation.” Nevertheless,there are some actions that offer much and carry little risk or cost.

          Around the world people are adapting in surprising ways,especially in some poor countries,Floods have some more damaging in Bangladesh in recent decades. Mohammed Rezwan saw opportunity where others saw only disaster. His not-for-profit organization runs 100 river boats that server as floating libraries,schools,and health clinics,and are equipment with solar panels and other communication facilities. Rezwan is creating floating connectivity(连接) to replace flooded roads and highways. But he is also working at a far more fundamental level:his staff people how to make floating gardens fish ponds prevent starvation during the wet season.

           Elsewhere in Asia even more astonishing actions are being taken. Chewang Nophel lives in a mountainous region in India, where he is known as the Ice Man. The loss of glaciers(冰川) there due to global warming represents an enormous threat to agriculture. Without the glaciers, water will arrive in the rivers at times when it can damage crops. Norphel's inspiration come from seeing the waste of water over winter, when it was not needed. He directed the wasted water into shallow basins where it froze, and was stored until the spring. His fields of ice supply perfectly timed irrigation(灌溉) water. Having created nine such ice reserves. Nophel calculates that he has stored about 200, 000mof water. Climate change is a continuing process, so Norhel's ice reserves will not last forever. Warming will overtake them. But he is providing a few years during which the farmers will, perhaps, be able to find other means of adapting.

        Increasing Earth's reflectiveness can cool the planet. In southern Spain the sudden increase of greenhouses (which reflect light back to space) has changed the warming trend locally, and actually cooled the region. While Spain as a whole is heating up quickly, temperatures near the greenhouses have decreased. This example should act as an inspiration for all cities. By painting buildings white, cities may slow down the warming process.

        In Peru, local farmers around a mountain with a glacier that has already fallen victim to climate change have begun painting the entire mountain peak white in the hope that the added reflectiveness will restore the life-giving ice. The outcome is still far from clear, But the World Bank has included the project on its of ‘100 ideas to save the planet”.

        More ordinary forms of adaptation are happening everywhere. A friend of mine owns an area of land in western Victoria. Over five generations the land has been too wet for cropping. But during the past decade declining rainfall has allows him to plant highly profitable crops. Farmers in many countries are also adapting like this—either by growing new produce, or by growing the same things differently. This is common sense, But some suggestions for adapting are not. When the polluting industries argue that we've lost the battle to control carbon pollution and have no choice but to adapt, it's a nonsense designed to make the case for business as usual.

        Human beings will continue to adapt to the changing climate in both ordinary and astonishing ways. But the most sensible form of adaptation is surely to adapt our energy systems to emit less carbon pollution. After all, if we adapt in the way, we may avoid the need to change in so many others.

        Dust on furniture may be bad news for waistlines (腰围). But it's far too early to add dusting to a weight-loss plan. Dietary fats and other materials that make up indoor dust can send a signal to human fat cells, telling them to grow. That process, in turn, might slow the body's rate of burning energy. Such changes could add to any weight problems a person might have.

        “We don't know what that means to long-term health and certain diseases yet,” says Heather Stapleton, one of the study's authors. But she notes that her team's findings also raise a question of whether pollutants in dust might play some role in the growing, global problem of obesity (肥胖).

        Stapleton and her colleagues collected dust from homes and offices. Studies found that some materials in the dust could turn on a protein (蛋白质) called PPAR-gamma 1. It's found in many human tissues. Turning this protein on can cause fat cells to grow. Researchers think this protein may be involved in obesity. But a second study now finds evidence that certain fats are mostly to blame. Cooking oils may send out some of these fats into the air, where they eventually find their way into house dust. Or, the authors say, the fats might enter house dust as part of the hair or skin cells shed (脱落) by people or pets.

        “While the findings are amazing,” says Mitchell Lazar, another study author, “these findings need to be taken as very limited.” Indeed, he adds several cautions about how the findings should be understood. “For one thing, people eat these fats in foods all of the time. That is likely to be a lot more than would be consumed from indoor dust,” he said.

        An earthquake is one of the most common natural disasters. It may cause great damage.  So it is wise to learn some simple safety tips to protect yourself or your family members.

        Fragile items, like those made of glass should usually be placed on a lower surface, near the ground instead of placing them on cupboards higher up. Never place them near your bed, sofas and other furniture where you would be sitting or lying down. When there is a strong movement, these pieces will fall on the floor directly and not on you.

        There is a strong chance of short circuits(短路)and fire breakouts during an earthquake. Make sure you turn off electrical connections and gas immediately when an earthquake happens.

        During an earthquake, lie beneath an object that is not easily damaged. Do not go near objects that could directly fall on you. Never use the elevator to go down. Stay inside until the shaking stops and it is safe to go outside. Research has shown that most injuries happen when people inside buildings try to go out. Use the staircases at all times.

        If you are outdoors, do not take shelter under a tree, streetlights, electric poles or tall buildings. If you are driving, stop your car and stay in a safe place. Do not park your car under a tree or any tall object.

        If trapped in debris (瓦砾堆), cover your mouth with a handkerchief or clothing. Tap on a pipe or wall so rescuers can find you. Use a whistle (哨子) if one is available. Never shout for help. Shouting can cause you to breathe in dangerous amounts of dust. Do not light a match because you may burn yourself. Do not move about or kick up dust.

        A ten-year-old from Howell, Michigan is being praised as a hero thanks to his persistence (坚持) that led to saving the life of an elderly neighbor. The event happened late in an evening when Danny DiPietro was being driven home from hockey practice by his mom.

        That's when the young boy noticed an open garage (车库) and a figure that he believed was a dog outside an apartment building near his house. Given the freezing cold weather, the young boy got a feeling that something was not right. But instead of dismissing it like most kids his age would have, he insisted that his mother, Dawn, find out what was going on. Dawn tried to make Danny believe that no one would leave a dog out in such cold weather, but he refused to take no for an answer.

        Dawn finally gave in and decided to drive to the area with the family dog and see if there was any truth to Danny's hunch (直觉). Sure enough, as she got closer to the apartment building she noticed a garage that was wide open and someone waving madly for help. Upon getting there, she realized that it was not a dog the young boy had seen, but Kathleen St. Onge. The 80-year-old had fallen down on some ice in her garage and had been lying there for two hours, unable to get up.

        Dawn rushed home to get her husband to help and called 911. The two then returned with some blankets to cover Ms. St. Onge, while they waited for the ambulance (救护车) to arrive. Though still in hospital, the elderly woman is recovering well and forever grateful to Danny, for following up on his hunch!

        At the end of August this year I moved from London, UK, to a small town in Quebec, Canada, called Matane to work as an English language assistant. Patience is a word that has appeared in many forms over the past two months.

        I don't see myself as being the most patient person in the world but there was something that struck me on my first week of work. I had just finished a session with two students and just as they were leaving the classroom, one of the students turned back and said, “Thank you for your patience.” That was an early reminder of the importance of being patient as a teacher. It also made me reflect on the language teachers that I have had over the years, ones that demonstrated a high level of patience and understanding that has shaped my language learning path. Moreover, it helped me to realize the importance of demonstrating patience in the classroom as it can be the difference between building someone's confidence in a language or breaking down their confidence entirely.

        Living my life constantly in French is not easy but the people of Quebec are very patient. They repeat things several times and they are more than happy to wait while I find the correct words to express myself and find the correct word order. It's a learning process but with the patience of others, the process is slightly less nervous. At the end of the day, making mistakes shows you are trying and I think that is greatly appreciated by Quebecers.

        When I first arrived in Matane I kept getting headaches from having to concentrate all the time due to the language and even overhearing other people's conversations was hard work! I had to keep reminding myself that it would take time, and two months later the headaches are a distant memory and my ears have become more tuned to their accent. The key is to be patient with yourself.
