Your house may have an effect on your figure. Experts say the way you design your home could play a role in whether you pack on the pounds or keep them off. You can make your environment work for you instead of against you. Here are some ways to turn your home into part of your diet plan.

    Open the curtains and turn up the lights. Dark environments are more likely to encourage overeating, for people are often less self-conscious(难为情) when they're in poorly lit places — and so more likely to eat lots of food. If your home doesn't have enough window light, get more lamps and flood the place with brightness.

    Mind the colors. Research suggests warm colors fuel our appetites. In one study, people who ate meals in a blue room consumed 33 percent less than those in a yellow or red room. Warm colors like yellow make food appear more appetizing, while cold colors make us less hungry. So when it's time to repaint, go blue.

    Don't forget the clock — or the radio. People who eat slowly tend to consume about 70 fewer calories(卡路里) per meal than those who rush through their meals. Begin keeping track of the time, and try to make dinner last at 30 minutes. And while you're at it, actually sit down to eat. If you need some help slowing down, turning on relaxing music. It makes you less likely to rush through a meal.

    Downsize the dishes. Big serving bowls and plants can easily makes us fat. We eat about 22 percent more when using a 12-inch plate instead of a 10-inch plate. When we choose a large spoon over a smaller one, total intake(摄入) jumps by 14 percent. And we'll pour about 30 percent more liquid into a short, wide glass than a tall, skinny glass.

    You may be surprised to learn that English gets 30 to 45 percent of its words from French. The reason goes back to the year 1066, when Norman forces invaded（入侵）what is now Britain. The Normans were from northern France and spoke French. During the Norman occupation, French became the language of England's rulers and wealthy class. This lasted for more than 300 years. Other people in England continued to speak English during this period.

    Over time, the two languages combined and shared words. Some researchers believe that about 10,000 French words eventually entered the English language. However, although English took many French words, their meanings have not always stayed the same. Sometimes the differences in meanings can be very important, and lead to funny or strange situations if the words are used in the wrong way.

    Take, for example, the French word college. In English, college can often be used in place of the word university, or sometimes as a school within a university. However, in French, college actually means “middle school”, or the level of schooling for students in grades five or six through eight.

    There are many other similar words in the two languages with completely different meanings. In English, the word chat is a verb which means “to talk casually”; but in French, the word chat is the word for an animal: a cat.

    If an English speaker says someone is jolly, that means they are cheerful or friendly. But in French, jolie means someone is good-looking or pleasant to look at. In any case, both are nice things to say to someone.

    Being sociable looks like a good way to add years to your life. Relationships with family, friends, neighbours, even pets, will all do the trick, but the biggest longevity(长寿) boost seems to come from marriage or an equivalent relationship. The effect was first noted in 1858 by William Farr, who wrote that widows and widowers(鳏夫) were at a much higher risk of dying than their married peers. Studies since then suggest that marriage could add as much as seven years to a man's life and two to a woman's. The effect holds for all causes of death, whether illness, accident or self-harm.

    Even if the odds are stacked against you (the conditions are not favourable), marriage can more than compensate. Linda Waite of the University of Chicago has found that a married older man with heart disease can expect to live nearly four years longer than an unmarried man with a healthy heart. Likewise, a married man who smokes more than a pack a day is likely to live as long as a divorced man who doesn't smoke. There's a flip side, however, as partners are more likely to become ill or die in the couple of years following their spouse's death, and caring for a spouse with mental disorder can leave you with some of the same severe problems. Even so, the odds favour marriage. In a 30-year study of more than 10,000 people, Nicholas Christakis of Harvard Medical School describes how all kinds of social networks have similar effects.

    So how does it work? The effects are complex, affected by socio-economic factors, health-service provision, emotional support and other more physiological mechanisms(机制). For example, social contact can boost development of the brain and immune system, leading to better health and less chance of depression later in life. People in supportive relationships may handle stress better. Then there are the psychological benefits of a supportive partner.

    A life partner, children and good friends are all recommended if you aim to live to 100.The best social network is still being mapped out, but Christakis says: “People are interconnected, so their health is interconnected.”

    Since English biologist Charles Darwin published On the Origin of Species in 1859, scientists have vastly improved their knowledge of natural history. However, a lot of information is still of the speculation, and scientists can still only make educated guesses at certain things.

    One subject that they guess about is why some 400 million years ago, animals in the sea developed limbs (肢) that allowed them to move onto and live on land.

    Recently, an idea that occurred to the US paleontologist (古生物学家) Alfred Romer a century ago became a hot topic once again.

    Romer thought that tidal (潮汐的) pools might have led to fish gaining limbs. Sea animals would have been forced into these pools by strong tides. Then, they would have been made either to adapt to their new environment close to land or die. The fittest among them grew to accomplish the transition (过渡) from sea to land.

    Romer called these earliest four-footed animals “tetrapods”. Science has always thought that this was a credible theory, but only recently has there been strong enough evidence to support it.

    Hannah Byrne is an oceanographer (海洋学家) at Uppsala University in Sweden. She announced at the 2018 Ocean Sciences Meeting in Oregon, US, that by using computer software, her team had managed to link Homer's theory to places where fossil deposits (沉积物) of the earliest tetrapods were found.

    According to the magazine Science, in 2014, Steven Balbus, a scientist at the University of Oxford in the UK, calculated that 400 million years ago, when the move from land to sea was achieved, tides were stronger than they are today. This is because the planet was 10 percent closer to the moon than it is now.

    The creatures stranded in the pools would have been under the pressure of “survival of the fittest”, explained Mattias Green, an ocean scientist at the UK's University of Bangor. As he told Science, “After a few days in these pools, you become food or you run out of food... the fish that had large limbs had an advantage because they could flip (翻转) themselves back in the water.”

    As is often the case, however, there are others who find the theory less convincing. Cambridge University's paleontologist Jennifer Clark, speaking to Nature magazine, seemed unconvinced. “It's only one of many ideas for the origin of land-based tetrapods, any or all of which may have been a part of the answer,” she said.

    When the company was small, Google cared a lot about getting kids from Harvard, Stanford, and MIT. But Laszlo Bock, Google's former Senior Vice President of People Operations, said it was the "wrong" hiring strategy. Experience has taught him that there are exceptional kids at many other places, from state schools in California to those in New York. "What we find is that the best people from places like these are just as good if not better as anybody you can get from any Ivy League school," said Bock, who authored a book titled "Work Rules!"

    So what else does Google not care about:

    Grades: Google's data shows that grades predict performance for the first two years of a career, but do not matter after that.

    Brain-teasers: Gone are interview questions such as: Why are manhole covers (井盖) round? How many golf balls can fit in a school bus? "Our research tells us those questions are a waste of time," Bock said. "They're a really coachable skill. The more you practice, the better you get at it."

    Here's what Google does care about:

    Problem solvers: Your cognitive (认知的) ability, or how well you solve problems.

    Leaders: The idea is not whether you were president of the student body or vice president of a bank, but rather "When you see a problem, do you step in and help solve it?" and then critically, "Are you willing to let somebody else take over, and make room for somebody else? Are you willing to give up power?"

    Googleyness: That's what Google calls its cultural fit. It's not "Are you like us?" Bock said. "We actually look for people who are different, because diversity gives us great ideas."

    "What's most important is that people are intellectually humble, willing to admit when they're wrong, and care about the environment around them ...because we want people who think like owners not employees," Bock said.

Traditionally, businesses use name badges(胸卡) for security and personal identity; the whole look also contributed to brand identity. But the use of name badges has so much more to offer: 

{#blank#}1{#/blank#}Name badges complete the overall look of an employee. Businesses who carry out this practice show that they pay attention to detail, no matter how small, giving the staff a professional look. Customers are more comfortable dealing with someone who looks professional and well trained. 

Name badges give employees identity. Name badges can make employees feel better about their jobs because they are not just nameless people. Name badges also promote a friendly environment, which leads to happier employees. {#blank#}2{#/blank#} Furthermore, the knowledge of being easily identified also makes an employee perform better, lest(以免) they be reported for bad service.

Name badges promote communication. {#blank#}3{#/blank#} This allows for easier communication, and employees are able to assist customers better when they know exactly what the customer wants or needs. A name can certainly make a big difference, not just for overall customer experience, but for the business as well. 

Name badges lend an air of familiarity. Customers are more comfortable when they know who they are speaking to or who is assisting them. Employees may also be required to find out the customer's name, all in the spirit of providing personalized service. {#blank#}4{#/blank#}

Name badges keep security in check. While name badges can keep businesses secure by identifying that the right people are where they should be, they also make customers feel secure by knowing who they are dealing with. {#blank#}5{#/blank#}

A．Name badges come in different colors and styles.

B．Name badges make employees look more professional.

C．Satisfied employees, in turn, deliver better customer service.

D．It's easier to talk to someone when you can address them by name.

E．In companies using name badges, the employees are more efficient.

F．Customers won't risk mistaking another customer for a member of the staff.

G．As a result, name badges make employees more approachable and business smoother.
