阅读理解

    Humans are much worse at estimating risk than we think we are. While we overestimate the risk of rare but disastrous occurrences, such as being attacked by a shark, many of us seriously underestimate the risk of behaviors that reduce our lifespan (寿命), such as smoking.

    In fact, there are two types of risks — acute and chronic. Acute risks are those that may kill you immediately, such as a car accident.

    Chronic risks don't kill you immediately but rob you of your life a little at a time. If you choose to eat an unhealthy diet, for instance, you may appear to be getting away with this, but you risk developing illnesses in future that may shorten your life.

    The problem is we value things much less when they occur in the future. Distant events are abstract — we don't know how and when they might affect us -~ so we care less about them.

    Take smoking for example. It is just about the worst choice you can make for your health. Every two cigarettes that you smoke takes 30 minutes off your lifespan.

    In contrast, eating vegetables is clearly very good for you, with each serve increasing your lifespan by two hours. This is a massive health gain and clearly should be a strong motivator for you to eat healthily.

    Drinking coffee is also good for you, though with limited health gains. Each cup of coffee (assuming you drink reasonably), is associated with approximately a ten-minute gain in your lifespan.

    Even drinking alcohol may add to your lifespan, with each serve adding 30 minutes to the length of your life. But this health gain is only true for the first drink; following drinks shorten lifespan. Alcohol also causes an acute risk when consumed in excess. Too much drinking gives you a 25 in one million chance of sudden death.

    We shouldn't be too nervous about exposure to risks. Life is all about making decisions about risks and rewards, and we all have a different starting point for what we consider acceptable risks to take. Even if we don't always make the healthiest decisions, at least we can make ones that are fully informed.

(1)、Which of the following belongs to acute risks?
A、Eating junk food every day. B、Being hit in a plane crash. C、Staying up late every night. D、Being too much overweight.
(2)、Why do people often ignore chronic risks?
A、They can often get away with them. B、They can rid themselves of their side effects. C、They don't reduce their lifespan. D、They will not cause immediate death.
(3)、Which habit will shorten your lifespan?
A、Eating vegetables every day. B、Smoking only one cigarette a day. C、Drinking a cup of coffee every day. D、Drinking alcohol reasonably.
(4)、What does the underlined phrase “in excess” in the 8th paragraph mean?
A、At random. B、In need. C、More than enough. D、Ahead of time.

    If you see a group of people dancing and singing on the street or in the railway station, you don't need to feel surprised. They are a flash mob(快闪族). Who are they Are they mobs? Don't be confused by their name. Actually, a flash mob is a group of people who gather suddenly in a public place, do something unusual for a brief period of time, and then quickly disappear.

    They are usually organized with the help of the Internet or other digital communications networks. The messages may be sent to friends, who send to more people. At a predetermined time, they gather and perform some activities such as exchanging books, coming together to look at the sky, waving their hands and yelling something at the top of their voice for 30 seconds. Then, they quickly disappear before the police can arrive Using mobile phones, the flash mob can change its place if the first one has been cancelled for any reason.

    Bill Wasik, senior editor of Hamper's Magazine, organized the first flash mob in Manhattan in May 2003 and the first successful flash mob gathered on June 3, 2003. Wasik claimed that he created the flash mob as a social experiment designed to laugh at fashion seekers and stress the cultural atmosphere of wanting to be an insider or part of "the next big thing”.

    Flash mob gatherings can sometimes shock people. Such an activity might seem amusing and magical, but it also might frighten people who are not aware of what is taking place. Undoubtedly, flash mob can serve as good political tools and have great potential, such as using flash mob to advertise a product.

    The flash mob is now becoming more and more popular. People use it to do many things. Flash mobs give people from all walks of life an opportunity to come together to create a memory.

    That robots, automation, and software can replace people might seem obvious to anyone who's worked in automotive manufacturing. But MIT business scholars Erik Brynjolfsson and Andrew McAfee's claim is more troubling and controversial. They believe that rapid technological change has been destroying jobs faster than it is creating them.

    They believe that technology increases productivity and makes societies wealthier, but it became clear to them that the same technologies making many jobs safer, easier, and more productive were also reducing the demand for many types of human workers. Technologies like the Web, artificial intelligence, and big data are automating many routine tasks. Countless traditional white-collar jobs, such as many in the post office and in customer service, have disappeared.

    As evidence, Brynjolfsson and McAfee point to a chart on which separate lines represent productivity and total employment in the United States. For years after World War II, the two lines closely tracked each other, with increases in jobs corresponding to increases in productivity. Then, beginning in 2000, the lines diverge; productivity continues to rise steadily, but employment suddenly shrinks. By 2011, a significant gap appears between the two lines, showing economic growth with no parallel increase in job creation.

United States Productivity and Employment

    But are these new technologies really responsible for a decade of lackluster (无生气) job growth? David Autor, an economist at MIT who has studied the connections between jobs and technology, doubts that technology could account for such a sudden change in total employment. Moreover, he also doubts that productivity has, in fact, risen steadily in the United States in the past decade. If he's right, it raises the possibility that poor job growth could be simply a result of a depressed economy. The sudden slowdown in job creation “is a big puzzle,” he says, “but there's not a lot of evidence that it's linked to computers.” “To be sure, computer technologies are changing the types of jobs available, but that is very different from saying technology is affecting the total number of jobs,” he adds. “Jobs can change a lot without there being huge changes in employment rates.”

    Lawrence Katz, a Harvard economist, says that while technological changes can be painful for workers whose skills no longer match the needs of employers, no historical pattern shows these shifts leading to a net decrease in jobs over an extended period. Still, Katz doesn't dismiss the notion that there is something different about today's digital technologies. Though he expects the historical pattern to hold, it is “genuinely a question,” he says. “If technology disrupts enough, who knows what will happen?”

    Some people think that success is only for those with talent or those who grow up in the right family, and others believe that success mostly comes down to luck. I'm not going to say luck, talent, and circumstances don't come into play because they do. Some people are born into the right family while others are born with great intelligence, and that's just the reality of how life is.

    However, to succeed in life, one first needs to set a goal and then gradually make it more practical. And, in addition to that, in order to get really good at something, one needs to spend at least 10,000 hours studying and practising. To become great at certain things, it'll require even more time, time that most people won't put in.

    This is a big reason why many successful people advise you to do something you love. If you don't enjoy what you do, it is going to feel like unbearable pain and will likely make you quit well before you ever become good at it.

    When you see people exhibiting some great skills or having achieved great success, you know that they have put in a huge part of their life to get there at a huge cost. It's sometimes easy to think they got lucky or they were born with some rare talent, but thinking that way does you no good, and there's a huge chance that you're wrong anyway.

    Whatever you do, if you want to become great at it, you need to work day in and day out, almost to the point of addiction, and over a long period of time. If you're not willing to put in the time and work, don't expect to receive any rewards. Consistent, hard work won't guarantee you the level of success you may want, but it will guarantee that you will become really good at whatever it is you put all that work into.

    It's natural to think about what goes into producing the food in your daily lunch bag. But have you ever stopped to consider the production techniques behind the bag itself? At the center of it is a woman named Margaret Knight.

    From her earliest years, Knight was a restless creator. In the article titled "TheEvolutionoftheGroceryBag", its writer mentions a few of her childhood projects. She was "famous for her kites", and "her sleds were the envy of the town's boys."

    To support her mother, she took a job at a cotton factory when she was 12. That same year she invented a shuttle system which helped to prevent injury. At the time,  she had no concept of patenting(得到……的专利权) her idea. What strengthened her place in history was her working experience at the Columbia Paper Bag Company. Here, instead of folding every paper bag by hand, Knight wondered if she might be able to make them cleanly and rapidly via an automated machine. The result was a working model of her elegant paper-folding machine. But this time, she wanted to go to the extra step and secure a patent on her creation, a brave move for a woman in the 19th century, when an extremely small percentage of patents were held by women.

    Not only did Knight file for a patent, she bravely defended her ownership of the bag machine idea. A man named Charles Annan said the creation was his own, arguing no woman could be able to design such a machine. Knight fought a legal battle against him and handed Annan a courtroom(法庭) defeat by presenting her detailed hand-drawn blueprints. Finally, Knight received her rightful patent in 1871.

    After making the machine, she continued to invent many other things like a paper feeding machine and a skirt protector. Knight, at the age of seventy, worked twenty hours a day on her 89th invention.
