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.

    Among all the fast growing science and technology, the research of human genes, or biological engineering as people call it, is drawing more and more attention now. Sometimes it is a hot topic discussed by people.

    The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with, such as cancer and heart disease. Every year, millions of people are murdered by these two killers. And to date, doctors have not found an effective way to cure them. But if the gene technology is applied, not only these two diseases can be cured completely, bringing happiness and more living days to the patients, but also the great amount of money people spend on curing their diseases can be saved, therefore it benefits the economy as well. In addition, human life span （寿命） can be prolonged.

    Gene technology can help people to give birth to more healthy and clever children. Some families, with the English imperial （皇家的） family being a good example, have hereditary diseases. This means their children will for sure have the family disease, which is a great trouble for these families. In the past, doctors could do nothing about hereditary diseases. But gene technology can solve this problem perfectly. The scientist just need to find the wrong gene and correct it, and a healthy child will be born.

    Some people are worrying that the gene research can be used to manufacture human beings in large quantities. In the past few years, scientists have succeeded in cloning a sheep, therefore these people predict that human babies would soon be cloned. But I believe cloned babies will not come out in large quantities, for most couples in the world can have babies in very normal way. Of course, the government must take care to control gene technology.

    The medical world is gradually realizing that the quality of the environment in hospitals may play an important role in helping patients to get better.

    As part of nationwide effort in Britain to bring art out of the museum and into public places, some of the country's best artists have been called in to change older hospitals and to soften the hard edges of modern buildings.

    Of the 2,500 national health service hospitals in Britain, almost 100 now have very valuable collections of present art in passages (走廊), waiting areas and treatment rooms.

    These recent movements first started by one artist, Peter Senior, who set up his studio at a Manchester hospital in northeastern England during the early 1970s. He felt the artist had lost his place in modern society, and that art should be enjoyed by a wider audience. A common hospital waiting room might have as many as 5,000 visitors each week. What a better place to hold regular exhibition of art! Senior held the first exhibition of his own paintings in the outpatients waiting area of the Manchester Royal Hospital in 1975. Believed to be Britain's first hospital artist, Senior was so much in demand that a team of six young art school graduates soon joined him.

    The effect is surprising. Now in the passages and waiting rooms, the visitor experiences a full view of fresh colors, playful images and restful courtyards.

    The quality of the environment may reduce the need for expensive drugs when a patient is recovering from illness. A study has shown that patients who had a view onto garden needed half the number of strong painkillers compared with patients who had no view at all or only a brick wall to look at.

    Throughout much of human history, man has been the measure of many, if not all, things. Lengths were divided up into feet and smaller units from the human hand. Other measures were equally characteristic. Mediterranean traders for centuries used the weight of grains of wheat to define (定义) their units of mass. The Romans used libra, forerunner of the pound, by referring to the weight of a carob (角豆树) seed.

    The sizes of similarly named units could also differ. The king's foot, used in France for nearly 1, 000 years after its introduction by Charlemagne in around 790 AD, was, at 32.5cm, around a centimeter shorter than the Belgic foot, used in England until 1300.Greek, Egyptian and Babylonian versions of water in a fixed container varied from one another by a few kilos, Nor was there agreement on such things within countries. In France, where there was no unified (统一的) measurement system at the national level, the situation was particularly terrible. The lieue (former measure of distance), for example, varied from just over 3 km in the north to nearly 6 km in the south.

    Although John Wilkins, an Englishman, first put forward a decimal system (十进制) of measurement in 1668, it was the French who in 1799 made it law. The Système International d'Unités (SI, or the metric system, as it is better known) developed from it and became the official measurement in all countries except Myanmar, Liberia and the United States. Now the International Bureau of Weights and Measures in Paris is set to give the metric system its biggest shake-up yet.

    At a meeting in Versailles, France, on November 16th, 2018, the world's measurement bodies are almost certain to approve a decision that will mean four out of the seven base SI units, including the kilogram, will follow the other three, including the metre, in being redefined in terms of the values of physical constants (物理常数).Each of the chosen constants has been measured incredibly precisely, which would mean that from May 20^th 2019 the constants will themselves be fixed at their current values for ever. Any laboratory in the world will then be able to measure, for example, the mass of an object as precisely as the accuracy of their equipment will allow.

    On a freezing cold day, a couple had to move into a small apartment because of their failure in business. The husband worked day and night to support the family but gave no care of his wife. So she thought, "He doesn't love me any more. He just cares about his business ... not me"．

    One day, she was about to take a shower when he stopped her at the door, "Let me take it first, okay?" "Why not me first?" she asked. "I am tired, honey, you take it later, okay?" She was entirely unhappy.

    One day, she found nothing to do and turned on his computer. A few words came into her sight. Reading them, she burst into tears. It was his diary：

    Today, I was quite sad. She asked me why I was always taking the shower first, and I said to her, "I was exhausted." She was unhappy. In her mind, I treated her not as well as usual, but what could I do? I was not as rich as before! We moved to the small apartment, and there was only one shower in the bathroom. It was so cold to take a shower in such a cold winter. But I found that if one person took the shower first, the room could get a little warmer. So every day I rushed to the bathroom first. I was thinking that, when she took the shower, the room would get warmer, even if it was only 1℃.

    Now I cannot give her a comfortable life, take her to good restaurants, or buy expensive dresses for her, but at least, I can give her 1℃ love.

    Self-driving cars have been backed by the hope that they will save lives by getting involved in fewer crashes with fewer injuries and deaths than human-driven cars. But so far, most comparisons between human drivers and automated vehicles have been unfair.

    Crash statistics for human-driven cars are gathered from all sorts of driving situations, and on all types of roads. However, most of the data on self-driving cars' safety have been recorded often in good weather and on highways, where the most important tasks are staying in the car's own lane and not getting too close to the vehicle ahead. Automated cars are good at those tasks, but so are humans.

    It is true that self-driving cars don't get tired, angry, frustrated or drunk. But neither can they yet react to uncertain situations with the same skill or anticipation of an attentive human driver. Nor do they possess the foresight to avoid potential perils. They largely drive from moment to moment, rather than think ahead to possible events literally down the road.

    To a self-driving car, a bus full of people might appear quite similar to an uninhabited corn field. Indeed, deciding what action to take in an emergency is difficult for humans, but drivers have sacrificed themselves for the greater good of others. An automated system's limited understanding of the world means it will almost never evaluate (评估) a situation the same way a human would. And machines can't be programmed in advance to handle every imaginable set of events.

    Some people may argue that the promise of simply reducing the number of injuries and deaths is enough to support driverless cars. But experience from aviation (航空) shows that as new automated systems are introduced, there is often an increase in the rate of disasters.

    Therefore comparisons between humans and automated vehicles have to be performed carefully. To fairly evaluate driverless cars on how well they fulfill their promise of improved safety, it's important to ensure the data being presented actually provide a true comparison. After all, choosing to replace humans with automation has more effects than simply a one-for-one exchange.
