“When I grow up， I want to be...”

    Almost all of us have thought about，or been asked to think about，our future careers. Our answers may differ greatly. Even now your aspirations(志向，抱负)may have changed from when you were in primary school.

    However，it seems that career choices aren't only based on personal taste. In a survey carried out by Teens， doctors，lawyers，and bankers were some of most popular careers that people said they hoped to follow. This is similar to a survey carried out in the UK in May 2016 by job website—Co.uk，in which medicine was the top choice among UK teenagers aged between 13 and 17.

    Medicine and law are two of the oldest and best known professions. Their prestige (威望) may come from the fact that doctors and lawyers are much­respected members of society，and they make good money. What's more， these professions are often seen as a sign of upward social class.

    It is equally unsurprising that banking is now one of the most common career choices. Youngsters worldwide think of banking and see the money rolling in. Wealth is increasingly becoming one of the most important indicators(标志) of a successful career.

    However，not every child has the makings of doctor， lawyer， or banker. They are those who see achievement and happiness in other areas. As the Teens' survey discovered，a variety of unconventional(非传统的) jobs—coffee shop owner，waiter at a fast food restaurant—are among teenagers' career choices. They can be equally interesting and rewarding jobs.

    With every choice comes responsibility and challenge，and all career paths require specific education and training，you have to learn to balance optimism(乐观主义)and confidence with being realistic about your particular talents and skills.

    I lived in a big city. It's noisy arid dirty and I got very tired. At the weekends I like to leave the city and get some fresh air and a good rest. A few weekends ago I decided to see my parents. I was really looking forward to it.

    My parents live a long way away. I went to see them with James, a friend, and we drove down on Friday night. In the middle of the trip it began to rain. The roads became very wet and it was difficult to drive. We arrived home just after midnight, feeling tired. The next morning it was still raining. James took his car to the local garage which was very good.

In the afternoon the weather became better. We wanted to go for a drive. My parents lent us their car. That was no good. Their car didn't work! We rang the garage. "Oh, no." they said, "your car won't be ready until tomorrow." So it wasn't possible to go for a drive. We decided to play a word game. When we didn't agree about a word we looked for a dictionary. It wasn't there. Suddenly my mother remembered. "I lent it to your sister. She took it with her when she left." The word game wasn't any good without a dictionary.

    On Sunday my mother dropped a suitcase on her foot and wig had to hire a taxi to take her to hospital. When James and I drove back we got stuck in a traffic jam (交通阻塞). Next time I want to have a rest. I'll stay in the city!

    Could the device, smartphone or PC，which you're using affect the moral decisions you make when using it? To test it, researchers presented multiple dilemmas to a sample set of 1,010 people. The participants were assigned a device at random.

    One case of the questions participants were asked is the classic “trolley (有轨电车) problem”: A runaway trolley is headed towards five people tied up on a set of train tracks. You can do nothing, resulting in the deaths of five people, or push a man off a bridge, which will stop the trolley. The practical response is to kill one man to save five lives, which 33.5 percent of smartphone users chose, compared to 22.3 percent of PC users.

    “What we found in our study is that when people used a smartphone to view classic moral problems, they were more likely to make more unemotional, reasonable decisions when presented with a highly emotional dilemma, ”Dr Albert Barque-Duran, the lead author of the study, told City, University of London. “This could be due to the increased time pressure often present with smartphones and also the increased psychological distance which can occur when we use such devices compared to PCs.”

    As for why the researchers started this study, Dr Barque-Duran noted, “Due to the fact that our social lives, work and even shopping take place online, it is important to think about how the contexts where we typically face moral decisions and are asked to engage in moral behavior have changed, and the impact this could have on the hundreds of millions of people who use such devices daily.” It's clear that we need more research on how our devices affect our moral decision making because we're using screens at an ever-increasing rate.

    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.

    The Dunning-Kruger effect is a type of cognitive bias (偏见) in which people believe that they are smarter and more capable than they really are. Essentially, low ability people do not possess the skills needed to recognize their own incompetence. The combination of poor self-awareness and low cognitive ability leads them to overestimate their own capabilities. This phenomenon is something you have likely experienced in real life, perhaps at a holiday family gathering. Throughout the course of the meal, a member of your extended family begins spouting off on a topic, boldly announcing that he is correct and that everyone else's opinion is stupid, uninformed, and just plain wrong. It may be plainly evident to everyone that this person has no idea what he is talking about, but he talks continuously, blithely oblivious (忘乎所以) to his own ignorance.

    The effect is named after researchers David Dunning and Justin Kruger, two social psychologists. They found incompetent people are not only poor performers, they are also unable to accurately assess and recognize the quality of their own work. These low performers were also unable to recognize the skill and competence levels of other people, which is part of the reason why they consistently view themselves as better, more capable, and more knowledgeable than others.

    This is the reason why students who earn failing scores on exams sometimes feel that they deserved a much higher score. They overestimate their own knowledge and ability and are incapable of seeing the poorness of their performance.

    “In many cases, the incompetent are often blessed with an inappropriate confidence, encouraged by something that feels to them like knowledge.” Dunning and his colleagues have also performed experiments where they ask respondents if they are familiar with terms related to subjects including politics, biology, physics, and geography. Along with genuine concepts, they added completely made-up terms. In one such study, approximately 90 percent of respondents claimed that they had at least some knowledge of the made-up terms.

    So what can you do to gain a more realistic assessment of your own abilities? Instead of assuming you know all there is to know about a subject, keep digging deeper. Once you gain greater knowledge of a topic, the more likely you are to recognize how much there is still to learn. Another effective strategy involves asking others for constructive criticism. While it can sometimes be difficult to hear, such feedback can provide valuable insights into how others perceive your abilities. Even as you learn more and get feedback, it can be easy to only pay attention to things that confirm what you think you already know. In order to minimize this confirmation bias, keep challenging your beliefs and expectations and seek out information that challenges your ideas.

    In the 1960s, while studying the volcanic history of Yellowstone National Park, Bob Christiansen became puzzled about something that, oddly, had not troubled anyone before: he couldn't find the park's volcano. It had been known for a long time that Yellowstone was volcanic in nature—that's what accounted for all its hot springs and other steamy features. But Christiansen couldn't find the Yellowstone volcano anywhere.

    Most of us, when we talk about volcanoes, think of the classic cone (圆锥体) shapes of a Fuji or Kilimanjaro, which are created when erupting magma (岩浆) piles up. These can form remarkably quickly. In 1943, a Mexican farmer was surprised to see smoke rising from a small part of his land. In one week he was the confused owner of a cone five hundred feet high. Within two years it had topped out at almost fourteen hundred feet and was more than half a mile across. Altogether there are some ten thousand of these volcanoes on Earth, all but a few hundred of them extinct. There is, however, a second les known type of volcano that doesn't involve mountain building. These are volcanoes so explosive that they burst open in a single big crack, leaving behind a vast hole, the caldera. Yellowstone obviously was of this second type, but Christiansen couldn't find the caldera anywhere.

    Just at this time NASA decided to test some new high-altitude cameras by taking photographs of Yellowstone. A thoughtful official passed on some of the copies to the park authorities on the assumption that they might make a nice blow-up for one of the visitors' centers. As soon as Christiansen saw the photos, he realized why he had failed to spot the caldera; almost the whole park-2.2 million acres—was caldera. The explosion had left a hole more than forty miles across—much too huge to be seen from anywhere at ground level. At some time in the past Yellowstone must have blown up with a violence far beyond the scale of anything known to humans.
