Conflict is on the menu tonight at the café La Chope. This evening, as on every Thursday night, psychologist Maud Lehanne is leading two of France's favorite pastimes, coffee drinking and the “talking cure”. Here they are learning to get in touch with their true feelings. It isn't always easy. They customers - some thirty Parisians who pay just under $2 (plus drinks) per session - care quick to intellectualize (高谈阔论)，slow to open up and connect. “You are forbidden to say ‘one feels,' or ‘people think',” Lehane told them. “Say ‘I think,' ‘Think me'.”

A café society where no intellectualizing is allowed? It couldn't seem more un-French. But Lehanne's psychology café is about more than knowing oneself: It's trying to help the city's troubled neighborhood cafes. Over the years, Parisian cafes have fallen victim to changes in the French lifestyle - longer working hours, a fast food boom and a younger generation's desire to spend more time at home. Dozens of new theme cafes appear to change the situation. Cafes focused around psychology, history, and engineering are catching on, filling tables well into the evening.

The city's psychology cafes, which offer great comfort, are among the most popular places. Middle-aged homemakers, retirees, and the unemployed come to such cafes to talk about love, anger, and dreams with a psychologist. And they come to Lehanne's group just to learn to say what they feel. “There's a strong need in Paris for communication,” says Maurice Frisch, a cafe La Chope regular who works as a religious instructor in a nearby church. “People have few real friends. And they need to open up.” Lehanne says she'd like to see psychology cafes all over France. “If people had normal lives, these cafes wouldn't exist”, she says, “If life weren't a battle, people wouldn't need a special place just to speak.” But them, it wouldn't be France.

    Everybody has one of those days when everything goes wrong. This is what happened to Harry.

    He got up one morning very late because he had forgotten to wind up his alarm clock（闹钟）. He tried to shave（刮脸）quickly and cut himself. When he got dressed he got blood all over his clean shirt, so he had to find another one. The only other shirt that was clean needed ironing（熨）, so he ironed it. While he was ironing it, there was a knock at the door. It was the man to read the electricity meter（表）. He showed him where the meter was, said good-bye and found that the iron had burnt a hole in his shirt. So he had to wear the one with the blood on it after all. By this time it was very late, so he decided he couldn't go to work by bus. He telephoned for a taxi to take him to work. The taxi arrived and Harry got in and began to read the newspaper.

    In another part of the town, a man had killed a woman with a knife and was seen to run away in a taxi. When Harry's taxi stopped outside his office, a policeman happened to be standing there. He saw the blood on Harry's shirt, and took him to the police station. He was kept till 3 o'clock in the afternoon before the police were sure that he was not the man they wanted. When he finally arrived at the office at about four, his boss took a look at him and told him to go away and find another job.

    Cheating can happen in a lot of different ways. When people cheat, it's not fair to other people, like the kids who studied for the test or who were the true winners of a game.

Many people like the action of cheating. It makes difficult things seem easy, like getting all the right answers on the test. But it doesn't solve the problem of not knowing the material and it won't help on the next test — unless the person cheats again.

    Some people lose respect for cheaters and think less of them. The cheaters themselves may feel bad because they know they are not really earning that good grade. And, if they get caught cheating, they will be in trouble at school, and maybe at home, too.

    Some kids cheat because they're busy or lazy and they want to get good grades without spending the time studying. Other kids might feel like they can't pass the test without cheating. Even when there seems to be a “good reason” for cheating, cheating isn't a good idea.

    If you were sick or upset about something the night before and couldn't study, it would be better to talk with the teacher about this. And if you don't have enough time to study for a test because of swim practice, you need to talk with your parents about how to balance swimming and school.

    A kid who thinks cheating is the only way to pass a test needs to talk with the teacher and his or her parents so they can find some solutions together. Talking about these problems and working them out will feel better than cheating.

    Program fools humans

    Have you ever been so bored that you started a conversation with a “chatbot (聊天机器人)”? You probably discovered quickly that it wasn't much fun, because the things it says hardly ever make any sense and chatting with it doesn't provide the same kind of back-and-forth as a human conversation.

    That might have made you wonder: will a computer ever be able to talk like a human?

    That day is certainly getting closer now. A computer program named “Eugene Goostman” has successfully passed the Turing test – by fooling people into thinking it was a 13-year-old boy, reported AFP on June 9.

    While you may have never heard of the Turing test, it means a lot in the world of artificial (人工的) intelligence.

    According to USA Today, the test was first invented in 1950 by Alan Turing, a British computer expert best known for his code-breaking work during World War II. In his test, a group of human judges take turns having keyboard conversations for five minutes with two subjects – a human and a piece of computer software. If up to 30 percent of the judges fail to tell the two apart, the program is considered to have passed the test.

“If a machine is indistinguishable (无法区分的) from a human, then it could be said to be ‘thinking',” wrote Turing in his paper Computing, Machinery & Intelligence back in 1950.

    No computer had ever passed the Turing test before. But this time, Eugene Goostman, developed by two Russian scientists to simulate (模拟) a 13-year-old boy, managed to convince 33 percent of judges that it was human.

    Machines are close to “reaching the milestone of communicating with us in a way that we are comfortable with”, Professor Kevin Warwick of the University of Reading, UK, told The Telegraph. “This brings closer the time in which robots start to play an active role in our daily lives.”

    Some people feel a bit disturbed by the news. They worry that computers will outsmart humans in the near future and take over the world. But Warwick said that it is unlikely that this will happen any time soon. After all, computers have only just learned to have a five-minute conversation, while we humans can do so much more than that.

    With its snow-covered mountains and a variety of wildlife, Yellow Stone National Park is one of the scenic treasures of the United States. Located primarily in Wyoming, the park hosts millions of visitors every year. If you plan to travel within the park, keep in mind advice from the National Park Service.

    Seasonal Travel

    Travel varies vastly from season to season. Roads are generally open in the summer except for cases of rock or mud slides, wild fires, accidents or road construction. Early snows in the fall can cause some roads to close temporarily. In the winter almost all roads are closed to motor vehicles, but snowmobiles and other snow vehicles with tracks are allowed. Roads begin to open for the spring by the latter part of April but can close if snowfall continues.

    Driving Time

    Grand Loop is the main road through Yellowstone National Park; it passes by most of the major attractions. These include Old Faithful, Yellowstone Lake and the Grand Canyon of Yellowstone. The maximum speed limit on the Grand Loop is 45 miles per hour, but the speed limit drops during some of the winding and twisting sections of this narrow road. Allow yourself at least two days to fully travel the loop due to the size of the park and being sometimes stuck in heavy traffic.

    Safety Awareness

    Buffalo(水牛)often block the roads in the park as they move through the fields. If a group is traveling across the road you are on  you can either wait for them to pass or find an alternative route. If you get out of your vehicle, the National Park Service says to stay at least 25 yards from any buffalo (and 100 yards or more away from bears and wolves). Buffalo are particularly unpredictable and charge people at speeds up to 30 mph.

    You can take your bicycle on any public roads and routes designed for bikes, but bicycles are not allowed on the park roads which are narrow with few shoulders. Altitudes range from 5, 300 to 8, 860 feet. The National Park Service recommends cyclists wear helmets and noticeable clothing.

Biologists from the John Innes Centre in England discovered that plants have a biological process which divides their amount of stored energy by the length of the night. This solves the problem of how to portion out (分配) energy reserves during the night so that the plant can keep growing, yet not risk burning off all its stored energy.

While the sun shines, plants perform photosynthesis (光合作用). In this process, the plants change sunlight, water and carbon dioxide into stored energy in the form of long chains of sugar, called starch (淀粉). At night, the plants burn this stored starch to fuel continued growth.

"The calculations are precise so that plants prevent starvation but also make the most efficient use of their food," said study co-author Alison Smith. "If the starch store is used too fast, plants will starve and stop growing during the night. If the store is used too slowly, some of it will be wasted. "

The scientists studied the plant Arabidopsis, which is regarded as a model plant for experiments. To give the plants some math tests, the biologists let night arrive unexpectedly early or late for them.

During one of the exams, they shut off the lights early on them that had been grown with twelve-hour days and nights. Putting them into darkness after only an eight-hour day means they didn't have time to store as much starch as usual. And this forced the plants to adjust their normal nightly rhythm.

Amazingly, even after this day length trick, the plants did very well in their exams and ended up with just five percent of starch left over at the end of the night. They had neither starved, nor stored starch that could have been used to fuel more growth.

The authors suggested that similar biological calculators may explain how a migratory bird, the little stint, can make a five-thousand-kilometer journey to their summer habitat in the Arctic and arrive with enough fat reserves to survive only approximately half a day more, on average.

The results of the study were published in e Life.
