The interview is an important event in the job-hunting process, because the 20 or 30 minutes you spend with the interviewer may decide whether or not you get the particular job you want. Therefore, it is important to remerber that your purpose during the interview may differ from that of the potential employer. You want to make yourself stand out as a whole person who has personal strengths and should be considered the right person for the job. It is encouraging to know that the interviewer's task is not to embarrass you, but to hire the right person for the job.

    Remember, job hunting is very competitive. Anything you can do to improve your interview techniques will be to your advantage. The following suggestions may help you land the most important job.

    Your goal in this interview is to make sure your good points get across. The interviewer won't know them unless you point them out , so try to do this in a factual and sincere manner.

    Don't say anything bad about your former employers. If you have been fired from a job and the interviewer asks about it, be honest.

    Show the interviewer that your are interested in the company by asking questions. Ask about responsibilities, working conditions, promotions opportunities and benefits of the job you are interviewing for.

    If at some point you decide the interview is not going well, do not let your discouragement show. You have nothing to lose by continuing a show of confidence, and you may have much to gain. It may be real, or it may be a test to see how you react to adverse conditions.

    Some interviewers may bring up salary early in the interview. At this time, you may indicate that you are more interested in a job where you can prove yourself that a specific salary. This politely passes the question back to the interviewer. If possble, you should negotiate for salary after you have been offered a job and have completed the paperwork.

    The Coolest Inventions

    An Oceans Vacuum(吸尘器)

    There's a collection of plastic trash in the middle of the Pacific Ocean. It's bigger than Texas and growing. The way to clean it up now is to catch it with nets. That is both costly and slow. Instead, the Ocean Cleanup Project proposes a 62-mile-long floating barrier that would use natural currents to trap trash. If next year's trials succeed, a full cleanup operation would aim to start in 2020. It could reduce the trash by 42% over 10 years.

    Easy-On Shoes

    In 2012, Matthew Walzer, a high school student with a disability, sent a note to Nike. “My dream is to go to college,” he wrote, “without having to worry about someone coming to tie my shoes every day.” Nike assigned a design team to the challenge. This year, they came out with their solution: the FlyEase. The basketball shoe can be fastened with one hand. A pair of Nike FlyEase shoes sells for $130.

    An Airport for Drones (无人机)

    As Amazon, Google, and others get ready for drone delivery service, there is one big question: What kinds of home bases will their drones have? Rwanda, in Africa, may have the answer. There, workers will soon start work on three “drone ports”. The goals is to make it easier to transport food, medical supplies, electronics, and other goods through the hilly countryside. Construction is set to be completed in 2020.

    Parents who help their children with homework may actually be bringing down their school grades. Other forms of parental involvement, including volunteering at school and observing a child's class, also fail to help, according to the most recent study on the topic.

    The findings challenge a key principle of modern parenting where schools expect them to act as partners in their children's education. Previous generations concentrated on getting children to school on time, fed, dressed and ready to learn.

    Keith Robinson, the author of the study, said, "I really don't know if the public is ready for this but there are some ways parents can be involved in their kids' education that leads to declines in their academic performance. One of the things that was consistently negative was their parents' help with homework." Robinson suggested that may be because parents themselves struggle to understand the tasks."They may either not remember the material their kids are studying now, or in some cases never learnt it themselves, but they're still offering advice."

    Robinson assessed parental involvement performance and found one of the most damaging things a parent could do was to punish their children for poor marks. In general, about 20% of parental involvement was positive, about 45% negative and the rest statistically insignificant.

    Common sense suggests it was a good thing for parents to get involved because "children with good academic success do have involved parents", admitted Robinson. But he argued that this did not prove parental involvement was the root cause of that success. "A big surprise was that Asian-American parents whose kids are doing so well in school hardly involved. They took a more reasonable approach, conveying to their children how success at school could improve their lives."

    At least 40% of Australian households now have at least one home “Internet of Things” device. These are fridges, window blinds, locks and other devices that are connected to the Internet.

    While the Internet of Things (IoT) may lead to more efficiency in our daily lives, my research shows that consumers are exposed to many risks by the use of IoT devices, ranging from disclosure of private information, to physical injury and problems with the devices themselves.

    Australia has no specific laws aimed at addressing IoT issues, and current laws intended to protect consumers have gaps and uncertainties when dealing with IoT devices. Many IoT device manufacturers and suppliers show little regard for customers' privacy. Some even make money from customer data.

    Consumer electronics company Vizio recently agreed to pay US regulators US $ 2.2 million, after failing to get appropriate permission from users to track their TV viewing habits.

    Late last year, the Norwegian Consumer Council found that a children's doll recorded anything said to it by children and sent the recordings to a US company. The company reserved the right to share and use the data for a broad range of purposes.

    IoT devices have the potential to collect more private data about individuals than was possible with previous devices. All this data can then be used to study consumers, predict our behavior, and sell us products at times when our willpower is lowest. Some companies are currently using technology to track consumers through stores and send their messages to mobile phones. This may be linked to our purchase history.

    Consumers are exposed to significant risks from IoT devices, from the use of data, to security flaws and devices no longer being supported. They should think long and hard about the risks they are taking on with IoT devices. Do you really need that internet-connected hairbrush?

    The computers changed our lives in the 1980s, the Internet changed our lives in the 1990s, and the robots will change our lives in the new century.

    Do you think there will be robots in people's homes? It's not a dream that every home will have a robot.

    Now, robots are not only able to help people do the housework, they can also help the doctors do the difficult operations, play chess with people, play the piano and so on.

    A new cooking robot is used in Beijing. It can cook all the dishes on the menu, you only need to wait two to four minutes. In the future, the robot will be a nurse, a security guard, or a partner in your life.

    Experts believe robots will be used everywhere from the industrial robots to service robots. In the future, robots will become part of the family, and provide close service for people. We all look forward to the new robot age.

In a time when a dangerous number of people are overweight, many people seem to have forgotten the most important way to keep healthy and slim—exercise. And as a new study carried out on mice in the lab has shown, exercise done early in life can reward you in your adult years.

    A team of researchers at the University of California studied the effects of early exercise on adult physical activity, body mass and eating. They found that early-age exercise in mice has positive effects on adult levels of voluntary exercise in addition to reducing body mass.

    "These results may have an effect on the importance of regular physical education in elementary and middle schools," said Theodore Garland, a professor of biology, who led the research project. "If kids exercise regularly through their school years, then they may be more likely to exercise as adults, which could have far-reaching positive effects on human health and well-being."

    Although the positive effects of early-life exercise lasted for only one week, it is important to note that one week in the life of a mouse is the same as about nine months for humans. "Our results suggest that any positive effects of early-life exercise on adult exercise will need to be kept up if they are to be long-lasting."

    His team of researchers found, too, that all mice that had access to early exercise were lighter in weight than non-exercised mice.

    Garland explained that, in general, exercise will stimulate appetite sooner or later. However, it is possible that certain types of exercise, done for certain periods of time or at certain light levels, might not stimulate appetite much, if at all, at least in some individuals.

    "If we could understand what sorts of exercise these might be, then we might be able to tailor exercise recommendations in a way that would bring the benefits of exercise without increase in appetite, leading to a better chance of weight loss," he said.
