    American researchers found females are the more talkative sex because of a special “language protein” in the brain.

    The study, conducted by neuroscientists (神经学家) and psychologist from the University of Maryland, concluded that women talked more because they had more of the Foxp2 protein. The research, published in the Journal of Neuroscience, found that higher levels were found among humans that were women but in rats that were males. Their findings came after it was previously claimed that ladies speak about 20,000 words a day — over 13,000 more than men. “This study is one of the first to report a sex difference in the expression of a language-associated protein in humans or animals,” said Prof Margaret McCarthy, who led the study. In their study, the researchers attempted to determine what might make male rats more vocal than their female friends.

    They separated four-day-old rats from their mothers and then counted the number of times they cried out in the “ultrasonic (超声波的) range”, the frequencies higher than humans can hear, over five minutes. While both sexes called out hundreds of cries, the males called out twice as often, they found. But when the pups were returned to their mother's cage, she fussed over her sons first. Tests conducted on the parts of the brain known to be associated with vocal calls showed the male pups have up to twice as much Foxp2 protein as the females. The researchers then increased the production in the brains of female pups and reduced it in males. This led to the female rats crying out more often and their mothers showing more interest in them. In contrast, males became less “talkative”.

    The researchers then tested samples from ten children, aged between three and five, which showed that females had up to 30 per cent more of the Foxp2 protein than males, in a brain area key to language in humans.

    “Based on our observations, we assume higher levels of Foxp2 in girls and higher levels of Foxp2 in male rats is an indication that Foxp2 protein levels are associated with the more communicative sex,” said Prof McCarthy.

    “Our results imply Foxp2 as a component (成分) of the neurobiological basis of sex differences in vocal communication in mammals.”

    People in the western state of California who are in the United States illegally can now request a driver's license. The law went into effect on January l. California is not the first American state with such a law, but it has the largest number of illegal immigrants. More than a million people began to request licenses shortly after the new state law went into effect. Among them was Christian Alvarado. Mr. Alvarado entered the United States from El Salvador eight years ago without permission from the U.S. government. Some call such people "illegal immigrants." Others call them "undocumented immigrants".

    Mr. Alvarado thinks it so exciting, for he has been waiting for the license for a long time. But some are worried that their personal information will be used to find them and deport them. Armando Botello is a spokesman for the California Department of Motor Vehicles, or DMV. He says people should not be afraid, for such information will not be shared.

    The new licenses are the same as licenses given to citizens except that they have the words "Federal Limits Apply". That means the license cannot be used to travel on an airplane or enter a federal building. Ana Garcia, working at the Central American Resource Center, says some illegal immigrants fear those words will be used to abuse them. Civil rights groups say the police and others will not.

    Dan Schnur, a political scientist at the University of Southern California, said that the main argument against the new law is that it rewards illegal behavior. But Professor Schnur argued that young, white Americans generally support immigration reform, including giving driver's licenses to illegal immigrants

    "It's simply because they grew up in a much more multicultural society than their parents or their grandparents did." Professor Schnur says he believes the changes in beliefs about illegal immigrants that have taken place in California will spread throughout the United States.

    Why do human beings still risk their lives under ground and doing one of the dirtiest and most dangerous jobs in the world? It is an increasingly urgent question, given the recent mining accidents in Sago, W. Va and Huntington, Utah. A small group of engineers and robotics experts look forward to a day in the not-too-distant future when robots and other technology do most of the dangerous mining work.

    Robotic technology, in particular, holds much promise, McAteer says, especially when it comes to mapping mines and rescuing trapped miners — the special operations of the mining industry.

    One of the first mining robots was developed five years ago at Carnegie Mellon University's Robotics Institute. It was called Groundhog. It used lasers(激光器) to “see” in dark tunnels and map abandoned mines—some of the most dangerous work in the business.

    The latest design is called Cave Crawler. It's a bit smaller than Groundhog, and even more advanced. It can take photos and videos and has more sensors that can detect the presence of dangerous gases. Incredibly, the robot has a real sense of logic. If it comes across an obstacle it gets momentarily confused. It has to think about what to do and where to go next. Sometimes it throws a fit just like a real person.

    The greatest problem, though, is cost. The money of the earliest research project was provided by the government, but that money had dried up, and it's not clear where future money will come from. Partly for that reason, and partly because of advances in safety, mining is not nearly as dangerous as it was in the past. Since 1990, fatalities(致命性) have declined by 67% and injuries by 51% , according to the National Mining Association.

    Some experts predict that robots in mines will serve much of the same function that they do in the automotive industry. The robots do the most boring and dangerous jobs,but won't get rid of the need for human workers.

    Forests are always losers at the Olympics, and that's unlikely to change anytime soon.

    For the winter games in PyeongChang, South Korea, virgin forest was destroyed on Mount Gariwang to accommodate ski runs. For the 2022 Winter Olympics in Beijing, a ski run is set to wipe out part of the Songshan National Nature Reserve. And let's not forget the 240 acres of Atlantic Forest that were leveled for the 2016 games in Rio de Janeiro to make way for a golf course.

    For the upcoming Tokyo games, environmental and human rights advocates have been raising alarms about the use of tropical (热带的) wood to build the New National stadium. Activists have fought against such environmental destruction. The damage is often permanent, threatens endangered plants and animals and in some cases, causes conflicts with native people. But frequently the country's organizing committee, and the International Olympic Committee (IOC) have found ways to make it reasonable — despite a paragraph in the Olympic Charter (宪章) that states that the IOC's role is to "encourage and support a responsible concern for environmental issues".

    "As it stands now, the IOC has little authority over a city's local organizing committee, which finally plans the event, " Chappelet, professor of public management at the University of Lausanne, told Earther. "Even if the IOC is dissatisfied with the way host cities have prepared for the games, they have no built-in systems to watch them so that they strictly follow the Olympic Charter." The only thing they can do if they're not happy is to withdraw (= take back) the right to organize the game. "But the IOC could include more enforcement (执行) systems into the contract they make with the host city," he added. That contract must be signed and obeyed by everyone and those who break it must be fined.

    Boykoff, the author of several books on the Olympics, suggested a similar solution. "The IOC could insist that host cities take their ecological (生态的) promises into account first, but instead they look the other way, time and time again," he said.

    When I was a little child, my parents divorced, making my mother a single parent. We had little money, but my mom gave me a lot of love. Each night, she sat me on her lap and spoke the words that would change my life, "Kemmons, you are certain to be a great man and you can do anything in life if you work hard enough to get it."

    At fourteen, I was hit by a car and the doctors said I would never walk again. Every day, my mother spoke to me in her gentle, loving voice, telling me that no matter what those doctors said, I could walk again if I wanted to do it badly enough. She drove that message so deep into my heart that I finally believed her. A year later, I returned to school—walking on my own!

    When the Great Depression(大萧条)occurred, my mom lost her job. Then I left school to support the family. At that moment, I was determined never to be poor again.

    My real change occurred on a vacation I took with my wife and five kids in 1951. I was angry that the second-class hotel charged an extra $2 for each child. That was too expensive for the average American family. I decided to open a motel(汽车旅馆)for families that would never charge extra for children. There were plenty of doubters at that time.

    Not surprisingly, mother was one of my strongest supporters. We experienced a lot of challenges. But with my mother's words deeply rooted in my soul, I never doubted we would succeed. Fifteen years later, we had the largest hotel system in the world—Holiday Inn. In 1979 my company had 1,759 inns in more than fifty countries with an income of $ 1 billion a year.

    You may not have started out life in the best situation. But if you can find a task in life worth working for and believe in yourself, nothing can stop you.

Teenage summer camps

    We helped on a nature reserve(保护区)for a week. We did different things every day, including cutting the reeds(芦苇),by the lake. Every day, we took turns to cook, in teams of five. When it was our teams turn, we made a simple dinner of pasta and salad for everyone. Judging by the fact that there was none left, we didn't do too badly!

    We stayed with families who had kids our own age, and because they were on a mid-term break they came with us on all the trips. So except when we were actually in a language class, we were spending time with our new friends. It was a great way to practice the language we had been working on in the classroom.

-Oliver

    Every morning we had the same breakfast, and then cleaned up the camp. When it was all completely tidy, we could head off for the day. The first time we went into the city, we were put into teams and given lists of things to spot, like statues, squares and other landmarks. With some help from the locals, my team found almost all of the things on our list and came second. We went to different museums and galleries in and around the city every day. It was a great chance to learn about another country and its history.

-Sarah

    We stayed in a youth center in the suburbs, and went into the center of town by bus every day. It was a good way to see a bit of the city, and it didn't take long to get to the theater where we had our classes. I loved the atmosphere in the old building, and we could walk around during our breaks and watch rehearsals(排练). We learned a great deal and I'm looking forward to putting it all into practice at my school drama club next term!
