Both men and women are livinglonger these days in industrialized countries.{#blank#}1{#/blank#}Ingeneral, they can expect to live six or seven years more than men. One reasonfor this is biological.

      One important biological factor thathelps women live longer is the difference in hormones between men and women.{#blank#}2{#/blank#}Between the ages of about 12 and 50,women produce hormones that are involved in fertility(生育能力). These hormones also have a positive effect on the heartand blood flow. In fact, women are less likely to have high blood pressure orto die from heart attacks.

    A new keyboard can tell whether you are its owner. The keyboard records information about the typing pattern and sends it to a computer program. The program then checks to see if the pattern matches the right user. If not, an alarm sounds, and the computer locks the typist out. It locks out anyone else, even if the person knows password. What's more, this device needs no batteries. It harvests all the energy it needs from the action of your typing. Besides, the keyboard is also self-cleaning and the keys are free of damage from water, oil and dirt.

    The keys of the new keyboard are made of the same inexpensive plastic that might be found on any other standard keyboard. But instead of being smooth, the keys have millions of tiny plastic nanowires (纳米线) on their surface area to every key, increasing the effective contact area between the plastics and fingers. This ensures that there's enough power to run the keyboard as someone types.

    Liming Dai, a scientist, did not work on the new keyboard, but he thinks the design could be important in getting better performance from a variety of devices. “It could also be applied to a touch screen, for instance,” Dai says. “Then smart phones and notepads could harvest energy from the action of someone typing or drawing.”

    “Future work might make the keyboard even more useful,” Dai adds. “A later design might build tiny capacitors(电容器) onto the nanowires,” he suggests. Capacitors are little devices that temporarily store electric charges. Those might then LEDs to light a Keyboard in the dark.

    Zhonglin Wang is a co-designer of the new keyboard. His team has build a working model of the keyboard. “If a company decides to fund(投资) its production, this keyboard could be in stores in as little as two years,” says Wang.

    “He is the best choice for goodwill ambassador.” Indian movie fans in China say.

    Indian actor Aamir Khan has got his major celebrity status in China. Aamir Khan was in China last week to promote his latest Hindi film Secret Superstar. During his weeklong stay, first in Shanghai and then in Beijing, the Indian actor also found out that he has become a major celebrity in a country where Hollywood's reach has been traditionally limited.

    Some local analysts compare his star status in China to that of Hollywood actors Tom Hanks, Tom Cruise and Leonardo DiCaprio. Others wonder if Khan is an activist actor. Still others describe him as a feminist（女权主义者）. The Chinese media seem to have called him Mishu, or Uncle Aamir. The surprising rise in popularity of the 52-year-old Bollywood star is owing to his striking movies. At more than 1 million, Khan has the most followers as an Indian on Sina Weibo, the country's Twitter-like platform.

    Secret Superstar had made more than 400 million yuan（$63 million）earlier this week. The story of a teenage Muslim girl's fight against ugly patriarchy（父权制）to realize her dreams was released in China on Jan 19.

    Last year, his film Dangal, inspired by the real journey of an Indian wrestler through a conservative landscape to turn his daughters into world-class athletes, had made nearly 1.3 billion yuan.

    In 2011, Khan's work first got major attention from Chinese moviegoers with Three Idiots, which was released in India much earlier. A statement on India's orthodox education system, similar to that of China, the Hindi film went along with the local audience. Film critics and fans alike recommended it to their friends.

    Some film critics say the education systems, gender discrimination（性别歧视）and domestic violence（家庭暴力）that Secret Superstar shows are among similarities of social issues in India and China. A series of “masterpieces” have made Khan an effective brand in China, in addition to his movie marketing and film devotion.

    The printing press has a long history. It was invented in Germany by Joannes Gutenberg around 1440, and brought to England by William Caxton in the 1470s.Yet the basic technology of printing remained the same up to the end of the 18th century, requiring two men to operate a wooden screw press by hand, producing about 200 impressions an hour. The 19th century was the period in which this process was mechanised, automated, and made many times faster.

    A key moment in the development of mass newspapers was the development of the steam-powered printing press, adopted by the times in 1814. The new presses were able to print per hour around five times the number produced by the machines. The editor, John Walter, had the machines fixed secretly at night, so that when his printers reported for duty the next morning the majority of them found that they were out of work. The Times went from a circulation of 5,000 a day in 1815 to around 50,000 in the middle of the century. This was not caused by the steam press, but neither could it have happened without it.

    Later developments improved this effect: the Applegath machine achieved 5,000 impressions per hour, and the Hoe press, an import from the United States, reached to 20,000 impressions per hour. Increase in the speed of papermaking in this period brought down the cost of printed materials both for the producer and the customer. In 1896, the Daily Mail was sold at the cost of only half a penny, and by 1900 it was selling nearly 1,000,000 copies a day.

    If print production was completely changed in those years, then so was its distribution. The appearance of the steam railway meant that for the first time newspapers could be distributed across the country on a daily basis.

    In the United States, when one becomes rich, he wants people to know it. And even if he does not become very rich, he wants people to think that he is. That is what "Keeping up with the Joneses" is about. It is the story of someone who tries to look as rich as his neighbors.

    The expression was first used in 1913 by a young American called Arthur Momand. He told this story about himself. He began earning $125 a week at the age of 23. That was a lot of money in those days. And he was proud of his wealth(财富). He got married and moved with his wife to a very rich neighborhood outside New York City. When he saw that rich people rode horses, Momand went horseback riding every day. When he saw that rich people had servants, Momand and his wife also hired a servant and gave big parties for their new neighbors. It was like a race, but one could never finish this race because one was always trying to keep up. The race ended for Momand and his wife when they could no longer pay for their new way of life. They moved back to an apartment in New York City.

    Momand looked around him and noticed that many people do things just to keep up with rich lifestyle of their neighbors. He saw the funny side of it and started to write a series of short stories. He called it"Keeping up with the Joneses", because"Jones"is a very ordinary(普通的) name in the United States. "Keeping up with the Joneses" came to mean keeping up with rich lifestyle of the people around you. Momand's series appeared in different newspapers across the country for over 28 years.

    People never seem to get tired of keeping up with the Joneses. And there are"Joneses"in every city of the world. But one must get tired of trying to keep up with the Joneses because no matter what one does, Mr. Jones always seems to be ahead.

    When I was small, my mother and I would walk to our local library in Franklin Square. As we didn't always have access to a reliable car, walking hand in hand was the most convenient way to get anywhere. It was at story time for children that both my mother and I made lasting friendships.

    Today, I am fortunate to live around the corner from the Cold Coast Public Library in Glen Head and a short walk to the Sea Cliff Children's Library. My 18-imonth-old son, Colin, and I find ourselves in Sea Cliff several times a week, meeting and making friends. Well, that is what many people don't understand-a library is more than books; it's a community.

    Sure, the library in Franklin Square was the place where I was introduced to Judy Blume novels. But it was also the place where I got my first email address in 1997. At the library, friends and I learned how to research colleges and search for scholarships on the Internet. The library was the place where we sometimes giggled(咯咯笑)too loudly, and where the librarians knew us by name. Their knowing our names wasn't a bad thing. When I came home from my first term at Binghamton University, Mary LaRosa, the librarian at the Franklin Square library, offered me my first teaching job.

    I now teach reading at Nassau Community College. My students are often amazed that they can check out books via their smartphones and virtually(虚拟地)visit a variety of Long Island libraries. The app used by Nassau and Suffolk county public libraries, as well as the college library, makes their homework easier by helping them find resources. Even though they can't always easily visit their local libraries, the library is always with them.
