    FLORENCE, Italy—Svetlana Cojochru feels hurt. The Moldovan has lived here seven years as a caregiver to Italian kids and the elderly, but in order to stay she's had to prove her language skills by taking a test which requires her to write a postcard to an imaginary friend and answer a fictional job ad.

    Italy is the latest Western European country trying to control a growing immigrant(移民) population by demanding language skills in exchange for work permits, or in some cases, citizenship.

    Some immigrant advocates worry that as hard financial times make it more difficult for natives to keep jobs, such measures will become more a vehicle for intolerance than integration(融合). Others say it's only natural that newcomers learn the language of their host nation, seeing it as a condition to ensure they can contribute to society.

    Other European countries laid down a similar requirement for immigrants, and some terms are even tougher. The governments argue that this will help foreigners better join the society and promote understanding across cultures.

    Italy, which has a much weaker tradition of immigration, has witnessed a sharp increase in immigration in recent years. In 1990, immigrants numbered some 1.14 million out of Italy's then 56.7 million people, or about 2 percent. At the start of this year, foreigners living in Italy amounted to 4.56 million of a total population of 60.6 million, or 7.5 percent, with immigrants' children accounting for an even larger percentage of births in Italy.

    Cojochru, the Moldovan caregiver, hoped obtaining permanent residence(居住权) would help her bring her two children to Italy; they live with her sister in Moldova, where salaries are among the lowest in Europe. She was skeptical that the language requirement would encourage integration.

    Italians always “see me as a foreigner,” an outsider, even though she's stayed in the country for years and can speak the local language fluently, she said.

    If you want to disturb the car industry, you'd better have a few billion dollars: Mom-and-pop carmakers are unlikely to beat the biggest car companies. But in agriculture, small farmers can get the best of the major players. By connecting directly with customers, and by responding quickly to changes in the markets as well as in the ecosystems(生态系统）, small farmers can keep one step ahead of the big guys. As the co-founder of the National Young Farmers Coalition (NYFC, 美国青年农会）and a family farmer myself. I have a front-row seat to the innovations among small farmers that are transforming the industry.

    For example, take the Quick Cut Greens Harvester, a tool developed just a couple of years ago by a young farmer, Jonathan Dysinger, in Tennessee, with a small loan from a local Slow Money group. It enables small-scale farmers to harvest 175 pounds of green vegetables per hour—a huge improvement over harvesting just a few dozen pounds by hand—suddenly making it possible for the little guys to compete with large farms of California. Before the tool came out, small farmers couldn't touch the price per pound offered by California farms. But now, with the combination of a better price point and a generally fresher product, they can stay in business.

    The sustainable success of small farmers, though, won't happen without fundamental changes to the industry. One crucial factor is secure access to land. Competition from investors, developers, and established large farmers makes owning one's own land unattainable for many new farmers. From 2004 to 2013, agricultural land values doubled, and they continue to rise in many regions.

    Another challenge for more than a million of the most qualified farm workers and managers is a non-existent path to citizenship — the greatest barrier to building a farm of their own. With farmers over the age of 65 outnumbering(多于）farmers younger than 35 by six to one, and with two-thirds of the nation's farmland in need of a new farmer, we must clear the path for talented people willing to grow the nation's food.

    There are solutions that could light a path toward a more sustainable and fair farm economy, but farmers can't clumsily put them together before us. We at the NYFC need broad support as we urge Congress to increase farmland conservation, as we push for immigration reform, and as we seek policies that will ensure the success of a diverse and ambitious next generation of farms from all backgrounds. With a new farm bill to be debated in Congress, consumers must take a stand with young farmers.

    People with bigger brains tend to score higher on standardized tests of intelligence, according to new study findings.

    However, the study author Dr. Michael A.McDaniel of the Virginia Commonwealth University in Richmond emphasized that these findings represent a general trend, and people with small heads should not automatically believe they are less intelligent. For instance, Albert Einstein's brain was "not particularly large", McDaniel noted." There's some relationship between brain size and intelligence on the average, but there's plenty of room for exceptions," he said.

    Interest in the relationship between brain size and intelligence grew in the1830s, when German anatomist(解剖学家) Frederich Tiedmann wrote that he believed there was "an unquestionable connection between the size of the brain and the mental energy displayed by the individual man". Since that statement, scientists have conducted numerous studies to determine if Tiedmann's assertion was correct. Most studies have looked into the link between head size and intelligence. More recently, however, researchers have published additional studies on brain size and intelligence, measured using MRI scan(核磁共振成像扫描).

    For his study, McDaniel analyzed more than 20 studies that looked into the relationship between brain size and intelligence in a total of 1,530 people. The studies showed that on the average, people with larger brain volume tended to be more intelligent. The relationship between brain volume and intelligence was stronger in women than men, and in adults than in children. McDaniel notes in the journal Intelligence.

    McDaniel is not sure why the relationship was stronger for adults and women. "Other research has shown that women, on the average, tend to have smaller brains than men, but score just as well—if not higher—in tests of intelligence," he said.

    McDaniel insisted that the relationship between brain size and intelligence is not a "perfect" one. "One can certainly find lots of examples of smaller-sized people who are highly intelligent," he said, "But, on the average, the relationship holds."

Londoners are great readers. They buy vast numbers of newspapers and magazines and of books — especially paperbacks, which are still comparatively cheap in spite of ever-increasing rises in the costs of printing. They still continue to buy "proper" books, too, printed on good paper and bound（装订）between hard covers.

    There are many streets in London containing shops which specialize in book-selling. Perhaps the best known of these is Charring Cross Road in the very heart of London. Here bookshops of all sorts and sizes are to be found, from the celebrated one which boasts of being "the biggest bookshop in the world" to the tiny, dusty little places which seem to have been left over from Dickens' time. Some of these shops stock, or will obtain, any kind of book, but many of them specialize in second-hand books, in art books, in foreign books, in books on philosophy, politics or any other of the countless subjects about which books may be written. One shop in this area specializes only in books about ballet!

    Although it may be the most convenient place for Londoners to buy books, Charring Cross Road is not the cheapest. For the really cheap second-hand books, the collector must venture off the beaten track, to Farringdon Road, for example, in the East Central district of London. Here there is nothing so impressive as bookshops. The booksellers come along each morning and pour out their sacks of books onto small hand carts. And the collectors, some professionals and some amateurs, have been waiting for them. In places like this they can still, occasionally, pick up for a few pence an old one that may be worth many pounds.

    "Have a nice day！" may be a pleasant gesture or a meaningless expression. When my friend Maxie says "Have a nice day" with a smile, I know she sincerely cares about what happens to me. I feel loved and safe since another person cares about me and wishes me well.

    "Have a nice day. Next！" This version of the expression is spoken by a salesgirl at the supermarket who is rushing me and my groceries out the door. The words come out in the same tone (腔调) with a fixed procedure. They are spoken at me, not to me. Obviously, the concern for my day and everyone else's is the management's attempt to increase business.

    The expression is one of those behaviors that help people get along with each other. Sometimes it indicates the end of a meeting. As soon as you hear it, you know the meeting is at an end. Sometimes the expression saves us when we don't know what to say. "Oh, you just had a tooth out? I'm terribly sorry, but have a nice day. "

    The expression can be pleasant. If a stranger says "Have a nice day" to you, you may find it heart­warming because someone you don't know has tried to be nice to you.

    Although the use of the expression is an insincere, meaningless social custom at times, there is nothing wrong with the sentence except that it is a little uninteresting. The salesgirl, the waitress, the teacher, and all the countless others who speak it without thinking may not really care about my day. But in a strange and comfortable way, it's nice to know they care enough to pretend they care when they really don't care all that much. While the expression may not often be sincere, it is always spoken. The point is that people say it all the time when they like.
