Honesty is a virtue, and telling a lie is morally wrong. But how can you know if someone is {#blank#}1{#/blank#}? The answer is, they're probably not. Traditional economics says that people are rational beings who will lie if it is {#blank#}2{#/blank#} their advantage. A recent university study has shown that, actually, we're pretty honest ―especially {#blank#}3{#/blank#} we're at home.

Researchers in Germany phoned people at home and asked them to toss a coin. There was a strong financial incentive (激励) to fake the result: if the coin landed tails-up, the participant would receive money or a gift voucher, while if the coin landed heads-up, they would get {#blank#}4{#/blank#}. Because they were on the phone, they knew there was no {#blank#}5{#/blank#} of getting caught if they lied. And yet people revealed the truth despite that they {#blank#}6{#/blank#} (receive) nothing. Over hundreds of tosses a coin will land tails-up roughly 50% of the time. In this study over half the people (55.6%) asked said that the coin landed heads-up. Most of them didn't pursue the reward at the {#blank#}7{#/blank#} of honesty.

    Previous studies had found that people were more dishonest. In those laboratory studies 75% of people, {#blank#}8{#/blank#} (include) some who faked the results, reported a winning coin and claimed a reward. So the research team guesses it's being in our own home {#blank#}9{#/blank#} makes us play fair. {#blank#}10{#/blank#}, what motivates people to do so remains unclear.

    Why do some people eat too much? Is it because they're hungry? Or is there a scientific{#blank#}1{#/blank#}(explain)?

    There are a number of theories to account{#blank#}2{#/blank#}overeating. One factor depends on the time of day. “It's all part of a routine,” says Randy Seeley,{#blank#}3{#/blank#}professor of psychiatry in Cincinnati. “You're hungry at noon because that's the time you{#blank#}4{#/blank#}(eat)lunch for the past 100 days.” Another reason we may eat more than necessary is that the body needs to satisfy a salt and sugar balance. Drinking alcohol also increases appetite, because the body wants something {#blank#}5{#/blank#}(absorb) the alcohol.

    {#blank#}6{#/blank#}(basic), overeating can also be a question of more biological factors. For instance, your body temperature can tell your brain that you feel hungry. “Your body temperature{#blank#}7{#/blank#}(drop) when it's time to eat, and eating warms you up,” says Gina Harlow, a paediatrics professor at Harvard University. Also, the smell of certain foods can make us imagine subconsciously the pleasure of eating{#blank#}8{#/blank#}. Harlow adds, “If you know you love French fires,{#blank#}9{#/blank#} (smell)them will make you want to eat them because you know how good they are,{#blank#}10{#/blank#}can lead to eating too many.”

    So, the next time you realize you've eaten too much, don't worry about it. You can always blame it on science.

    Cloning is a way of {#blank#}1{#/blank#}(make) an exact copy of another animal and plant{#blank#}2{#/blank#} has two major uses. One is{#blank#}3{#/blank#} gardeners use it to produce commercial quantities of plants. The {#blank#}4{#/blank#}is that it is valuable for research on new species and for medical research on animals. {#blank#}5{#/blank#}, the process of cloning is difficult to undertake.

    Many attempts to clone mammals failed. The first successful clone, Dolly the sheep, made the whole {#blank#}6{#/blank#}(science) world follow its process, though it had {#blank#}7{#/blank#} problems than the normal sheep. On the other hand, Dolly's appearance {#blank#}8{#/blank#}(raise) a storm of objections and had a great impact {#blank#}9{#/blank#} the media and public imagination. Different people have different opinions of it. However, scientists still wonder whether cloning will help {#blank#}10{#/blank#} harm us and where it is leading us.

    Bank of China and Alibaba are the dream employers for Chinese students, according to a new survey.

    The survey of more than 55,000 students, {#blank#}1{#/blank#}(conduct) by a research firm Universum, found that {#blank#}2{#/blank#}(rough)a quarter want to work for an international company, while only 9% want to work for a start-up. Five percent want to start {#blank#}3{#/blank#}own business.

    When it comes to desirable companies, business students{#blank#}4{#/blank#}(name)Bank of China the top choice for seven years, and it shows no signs of {#blank#}5{#/blank#}(give)up its lead.

    William Wu, manager of Universum, said that banking remains{#blank#}6{#/blank#}attractive industry for young Chinese. “China's government is now emphasizing the revolution of finance industry, {#blank#}7{#/blank#}leaves the younger generation with the impression that though banking is a {#blank#}8{#/blank#}(tradition)industry, there are still a lot of development {#blank#}9{#/blank#}(opportunity),” Wu said.

    Alibaba improved six places from 2014, {#blank#}10{#/blank#}(rank)second among business students. It held a record-breaking $25 billion IPO in September.

    Why do different people like different colors? The answer depends largely {#blank#}1{#/blank#} cultural values. To the Egyptians, green is a color {#blank#}2{#/blank#} stands for the hope and joy of spring, while for Muslims, it means heaven. Red is a symbol of good luck in many cultures. During the Spring Festival in China, children {#blank#}3{#/blank#}(give) money in a red envelope to bring good fortune in the New Year. For many nations, blue is a symbol of protection and religious beliefs. Greek people often wear a blue necklace hoping to protect {#blank#}4{#/blank#} (they) against evils.

    People's {#blank#}5{#/blank#}(choose) of colors is also influenced by their bodies' reactions toward them. Green is said to be the most restful color. It has the ability to reduce pain and relax people both mentally {#blank#}6{#/blank#} physically. When{#blank#}7{#/blank#}(work) in green environment, people have fewer stomach aches. Red can make a person's blood pressure{#blank#}8{#/blank#} (rise) and increase people's appetite. Many decorators will include different shades of red in the restaurant. And many commercial websites will have a red “Buy Now” button because red is a color that {#blank#}9{#/blank#}(easy) catches a person's eye. Unlike red, blue is believed to cause people to lose appetite. Therefore,{#blank#}10{#/blank#} you want to eat less, eating from blue plates can help.

    When I was a university student, I {#blank#}1{#/blank#} (attract) by the Chinese. So I got a job as a teacher in Wuhan three years ago. Thinking back, I realize it was the students I met in the first year and Chinese university life in general {#blank#}2{#/blank#} gave me the deepest impression.

    During my school days, I would rarely give up my spare time to any activity connected with study. Unless exams were approaching, my weekends were devoted to {#blank#}3{#/blank#} (have) fun or perhaps a part-time job. My Chinese classmates, on the other hand, {#blank#}4{#/blank#} (seem) to spend their entire waking hours studying. I understand {#blank#}5{#/blank#} competition in Chinese universities is extremely fierce. Nonetheless, their energy and motivation put {#blank#}6{#/blank#} (I) to shame.

    My first year in China was also my first year as a teacher. It was both challenging {#blank#}7{#/blank#} rewarding. One thing I know for certain is that my year in Wuhan helped me {#blank#}8{#/blank#}(change) for the better. Thanks to the politeness and {#blank#}9{#/blank#}(warm) of Chinese students, I overcame my fear of speaking in public and became more self-confident. Most {#blank#}10{#/blank#}(important), I met dozens of nice people and made many excellent friends.
