“When in Rome, do as the Romans do”, so when you want to do business in France, you have to get to know French culture, to make marketing plans, and to run your business by local laws.

    {#blank#}1{#/blank#} The French take great pride in their language, so anyone who does not speak it may run the risk of being disrespected by his French colleagues or business partners. Also, another reason why learning French is important is that it is a great way to show every possible French business partner that you care and respect their country's culture and language.

    There are obvious ways of greeting people in French. When you meet someone new, it's usual to shake his hand firmly and always look at the person in the eye. {#blank#}2{#/blank#}

        Dress well. {#blank#}3{#/blank#}Your business clothing is a reflection of your success and social status. Always try to be stylish. Women are advised to dress simply but elegantly. Wearing make-up is practiced widely by business women.

    The French are passionate about food, so lunches are common in doing business in France, which usually consist of an appetizer, main meal with wine, cheese, dessert and coffee, and normally take up to two hours. {#blank#}4{#/blank#}

    Do not begin eating until the host says, “Bon appetite”. Pass dishes to the left, keep wrists above the table and try to eat everything on the plate. {#blank#}5{#/blank#}This may suggest that you find the food tasteless. If eating in a restaurant, the person who invites always pays.

A. The French draw information about people based on their appearance.

B. This is a time for relationship building.

C. Maybe you have heard the expression.

D. Language should be the focus of anyone planning to do business in France.

E. Be careful with adding salt, pepper or sauces to your food.

F. When you meet a friend, kissing is common.

G. English and French are both spoken in formal occasions.

    Five weeks ago I had a total hip replacement surgery (髋关节置换手术). In Canada, we have great healthcare system. That means we get our new hips for free.

    My hip had been hurting me for years before I went to the doctor. Of course, it was free. She referred me to a surgeon, but the earliest appointment was in 10 months. That is what being free gets you. Ten months later, after some free X-rays, the surgeon told me I needed a surgery, which was about an 18-month wait, for some senior citizens had been on the operation list. Another 18 months! I dragged myself out of the surgeon, s office.

    Walking through the hospital, I thought about the situation. As the breadwinner of a large family, I couldn't wait that long, so I had to get to the front line. I was fully aware of what a Canadian should be like (Canadians are usually considered gentle and caring), but this time I really needed to fight for myself. At that very moment, in the shop window of the hospital, I saw a sign which read, “Volunteers Needed.” Suddenly, an idea occurred to me — I would get the job. Fortunately, they signed me up immediately because the average age of the volunteers at the shop was 75. They were desperate for some young blood.

    Every Friday morning, I was at the shop. While seeing the hospital staff, I'd casually ask, “What do you do?” Then I'd tell them, “Well, I'm getting my hip replaced — in 18 months.

    It's going to be so great when the pain stops.” Soon, all the staff got to know me. Naturally, in my next appointment, the surgeon recognized me. Moments later, I had a surgery date just weeks away.

    I had to say it was actually my volunteering that got me to the front of the line. And I'm not ashamed of it, for I intend to stick with the volunteering. Also, even when I cheated the system, I did it in a way that benefits society.

    Here is a record of the discussion about AI (artificial intelligence) conducted by several scientists:

    Scientist A: I would say that we are quite a long way off developing the AI, though I do think it will happen within the next thirty or forty years. We will probably remain in control of technology and it will help us solve many of the world's problems. However, no one really knows what will happen if machines become more intelligent than humans. They may help us, ignore us or destroy us. I tend to believe AI will have a positive influence on our future lives, but whether that is true will be partly up to us.

    Scientist B: I have to admit that the potential consequences of creating something that can match or go beyond human intelligence frighten me. Even now, scientists are teaching computers how to learn on their own. At some point in the near future, their intelligence may well take off and develop at an ever-increasing speed. Human beings evolve biologically very slowly and we would be quickly substituted. In the short term, there is the danger that robots will take over millions of human jobs, creating a large underclass of unemployed people. This could mean large-scale poverty and social unrest. In the long term machines might decide the world would be better without humans.

    Scientist C: I'm a member of the Campaign to Stop Killer Robots. Forget the movie image of a terrifying Terminator stamping on human skulls and think of what's happening right now: military machines like drones, gun turrets and sentry robots are already being used to kill with very little human input. The next step will be autonomous “murderbots” following orders but finally deciding who to kill on their own. It seems clear to me that this would be extremely dangerous for humans. We need to be very cautious indeed about what we ask machines to do.

    Each year there is an increasing number of cars on roads and streets as millions of new cars and trucks are produced. One out of every six Americans works at putting together the parts of cars, driving trucks, building roads or filling cars and trucks with gas. Americans won't live without cars!

    Most Americans would find it hard to think what life would look like without cars. However, some have realized the serious problems of the air pollution that is caused by the car.

    The polluted air becomes poisonous and dangerous to health.

    One way to get rid of the polluted air is to build a car that does not pollute. That's what several of the large car factories have been trying to do. But to build a clean car is easier said than done. Progress in this field has been slow.

    Another way is to take the place of the car engine by something else. Inventors are now working on steam cars as well as electric cars. Many makers believe that it will take years to develop a practical model that pleases man.

    To prevent the world from being polluted by cars, we'll have to make some changes in the way many of us live. Americans, for example, have to cut down on the number of their total cars. They are encouraged to travel and go to work by bicycle. Bicycling is thought to help keep the air clean.

    But this change does not come easily. A large number of workers may find themselves without jobs if a car factory closes down. Thus the problem of air pollution would become less important than that of unemployment.

    Although cars have led us to a better life, they have also brought us new problems.

    Compassion（同情）is a desire within us to help others. With effort, we can translate compassion into action. An experience last weekend showed me this is true. I work part-time in supermarket across from a building for the elderly. These old people are our main customers, and it's not hard to lose patience over their slowness. But last Sunday, one aged gentleman appeared to teach me a valuable lesson. This untidy man walked up to my register（收款机）with a box of biscuits. He said he was out of cash, had just moved into his room, and had nothing in his cupboards. He asked if we could let him have the food on trust. He promised to repay me the next day.

    I couldn't help staring at him. I wondered what kind of person he had been ten or twenty years before, and what he would be like if fortune had gone his way. I had a hurt in my heart for this kind of human soul, all alone in the world. I told him that I was sorry, but store rules didn't allow me to do so. I felt stupid and unkind saying this, but I valued my job.

    Just then, another man, standing behind the first, spoke up. If anything, he looked more pitiable, “Charge it to me,” was all he said.

    What I had been feeling was pity. Pity is soft and safe and easy. Compassion, on the other hand, is caring in action. I thanked the second man but told him that was not allowed either. Then I reached into my pocket and paid for the biscuits myself. I reached into my pocket because these two men had reached into my heart and taught me compassion.

Though known for being violent, six-foot-long Humboldt squid (鱿鱼) in the Pacific Ocean, are good communicators,

It is not news that the squid can rapidly change the color of their skin-making different patterns for communication something other squid species are also known to do.

Bot it is totally dark where the Humboldt squid live, more than one thousand feet below the ocean surface. So their pattern is invisible. Instead, a new study suggests that they create backlighting for the patterns by making their bodies glow, like the screen of an ereader.

"Right now, what blows my mind in there's probably squid talking to each other in the deep ocean and they're probably sharing all sorts of cool information." said Ben Burford, a graduate student at Stanford University.

Burford and his fallow researchers studied deep-water recordings made by remotely operated vehicles off the California coast. They found the squid make around 30 different patterns, some of which are only used around other squid, suggesting they're used for communication, The squid also appear to reorder the patterns, almost like words in a sentence.

"That's really exciting because then you can say a whole lot more based on their arrangement," Burford said. "So, they could for instance say, hey, that fish over there is mine, and I'm the ruling squid."

The findings could change the way scientists think about bioluminescence (生物荧光), which is used by many deep-sea animals to attract prey or a mate.

"We generally think of deep: sea stuff as having very simple displays because it's a low-light environment," said Mike Vecchione, a zoologist from the National Museum of Natural Museum of Natural History. "This turns some of our ideas about bioluminescence almost around upside down."

The deep ocean is a challenging place to study, so Vecchione said there may be much more complexity to discover.
