Louis Armstrong sang, "When you"re smiling, the whole world smiles with you." Romantics everywhere may be surprised to learn that psychological research has proven this sentiment to be true—merely seeing a smile (or a frown, for that matter) will activate the muscles in our face that make that expression, even if we are unaware of it. Now, according to a new study inPsychological Science, simply reading certain words may also have the same effect. Psychologists Francesco Foroni from VU University Amsterdam and Gun R.Semin from the University of Utrecht conducted two experiments to see if emotion language has an influence on facial muscle activity. In the first experiment, a group of students read a series of emotion verbs (e.g., "to smile," "to cry") and adjectives (e.g., "funny," "frustrating") on a monitor, while the activity of their zygomatic major (the muscle responsible for smiles) and corrugator supercilii (which causes frowns) muscles were measured. The results showed that reading action verbs activated the corresponding muscles. For example, "to laugh" resulted in activation of the zygomatic major muscle, but did not cause any response in the muscles responsible for frowning. Interestingly, when presented with the emotion adjectives like "funny" or "frustrating" the volunteers demonstrated much lower muscle activation compared to their reactions to emotion verbs. The researchers note that muscle activity is "induced in the reader when reading verbs representing facial expressions of emotion." Can this natural bodily reaction affect our judgments In another experiment, volunteers watched a series of cartoons and were unconsciously shown emotion verbs and adjectives after each one. They were then asked to rate how funny they thought the cartoons were. Half of the participants held a pen with their lips, to prevent them from smiling, while the remaining participants did not have their muscle movement blocked. The results reveal that even when emotion verbs are presented unconsciously, they are able to influence judgment—volunteers found cartoons to be funnier when they were preceded by smiling verbs than if they were preceded by frowning-related verbs. However, this effect only occurred in the volunteers who were able to smile—volunteers who had muscle movement blocked did not show this relationship between emotion verbs and how funny they judged the cartoons as being.The results of these experiments reveal that simply reading emotion verbs activates specific facial muscles and can influence judgments we make. The researchers note these findings suggest that "language is not merely symbolic, but also somatic," and they conclude that "these experiments provide an important bridge between research on the neurobiological basis of language and related behavioral research." The word "somatic" (Para. 4) most probably means _____.

One of the least appreciated but most remarkable developments of the past 60 years is the extraordinary growth of American agriculture. Farming now accounts for about one tenth of the gross domestic product yet employs less than 1 percent of all workers. It has accomplished this feat through exceptionally high growth in productivity, which has kept prices of food low and therebycontributed to rising standards of living. Furthermore, the exportable surplus has kept the trade deficit from reaching unsupportable levels. Agriculture not only has one of the highest rates of productivity growth of all industries, but this growth appears to have accelerated during the past two decades. Over the period 1948 to 2004, total farm production went up by 166 percent. The land used for farming dropped by one quarter over the 56-year period, and investment in heavy farm equipment and other capital expenditures decreased by 12 percent. Several developments drove these changes, beginning with the replacement of the remaining horses by tractors immediately after World War II and with the expanding use of fertilizers and pesticides. Later came the adoption of hybrid seeds, genetic engineering of plants and improved livestock breeding.A key element was the U.S. Department of Agriculture"s (USDA) extension service. Operating through land-grant universities and other organizations, it educated farmers on biotechnology, pest management and conservation. For many years, critics have claimed that modern agriculture is not sustainable, one of the major assertions being that it encourages erosion, which will eventually wash away most of the topsoil Lost topsoil, the argument goes, is virtually irreplaceable because it takes up to 300 years for one inch of soil to form. But a detailed study of two large areas, the Southern Piedmont and the Northern Mississippi Valley Loess Hills, showed that based on 1982 data, soil loss has dropped sharply from the very high rates of the 1930s. The study attributed the decrease in soil erosion to the USDA, which urged farmers after World War Ⅱ to adopt conservation practices such as strip cropping, whereby alternating rows are planted, and leaving plant residues in the fields year-round to inhibit water runoff. Despite being a robust contributor to the U.S. economy, modem agriculture is not without a dark side. Runoff of fertilizers, antibiotics and hormones degrade the environment and can upset the local ecology. If not grown properly, genetically modified crops could spread their DNA to conventional species. The "dark side" (Para. 5) implies that modern agriculture will _____.
Anecdotal evidence has long held that creativity in artists and writers can be associated with living in foreign parts. Rudyard Kipling, Pablo Picasso, Ernest Hemingway, Paul Gauguin, Samuel Beckett and others spent years dwelling abroad. Now a pair of psychologists has proved that there is indeed a link. As they report in the Journal of Personality and Social Psychology, WilliamMaddux of INSEAD, a business school in Fontainebleau, France, and Adam Galinsky, of the Kellogg School of Management in Chicago, presented 155 American business students and 55 foreign ones studying in America with a test used by psychologists as a measure of creativity. Given a candle, some matches and a box of drawing pins, the students were asked to attach the candle to a cardboard wall so that no wax would drip on the floor when the candle was lit. (The solution is to use the box as a candleholder and fix it to the wall with the pins.) They found 60% of students who were either living abroad or had spent some time doing so, solved the problem, whereas only 42% of those who had not lived abroad did so. A follow-up study with 72 Americans and 36 foreigners explored their creative negotiating skills. Pairs of students were asked to play the role of a seller of a petrol station who then needed to get a job and a buyer who would need to hire staff to run the business. The two were likely to reach a deadlock because the buyer had been told he could not afford what the seller was told was his minimum price. Nevertheless, where both negotiators had lived abroad 70% struck a deal in which the seller was offered a management job at the petrol station in return for a lower asking price. When neither of the negotiators had lived abroad, none was able to reach a deal. To check that they had not merely discovered that creative people are more likely to choose to live abroad, Dr Maddux and Dr Galinsky identified and measured personality traits, such as openness to new experiences, that are known to predict creativity. They then used statistical controls to filter out such factors. Even after that had been done, the statistical relationship between living abroad and creativity remained, indicating that it is something from the experience of living in foreign parts that helps foster creativity. Merely travelling abroad, however, was not enough. You do have to live there. Packing your beach towel and suntan lotion will not, by itself, make you Hemingway. The word "deadlock" (Para. 3) most probably means _____.
With Japan"s welfare system buckling under the demands of an ageing society, the world"s oldest man apologized yesterday for his longevity. As Tomoji Tanabe, 111, received his certificate from Guinness World Records, the former engineer, who never touches alcohol, said that his feat of survival was nothing special. "I have been around too long," he joked, "I amsorry." Mr. Tanabe added his customary explanation of how he has managed to reach such a ripe old age: "Not drinking alcohol is the best formula for keeping myself healthy," he said. Other residents of his village attributed Mr. Tanabe"s long life to a diet that consists chiefly of vegetables and very little fried food. His explanation fuels a continuing mystery about the ideal formula for longevity—as each new holder of the title is crowned, each attributes his or her success to diets, lifestyles and habits that differ widely. Some have said that fresh air is the key, others have been heavy smokers. Some have taken vigorous exercise, others have sworn by periods of inactivity. The Mayor of Miyakonojo, the village where Mr. Tanabe lives with his family, presented the certificate to its famous resident after nearly five months of birthdate verification by the Guinness World Records team. Mr. Tanabe unofficially inherited the title when its previous record-holder, Emiliano Mer-cado del Toro, of Puerto Rico, died in January, aged 115.The crowning of Mr. Tanabe, who was born in the southern island of Kyushi in 1895, brings the desired "double trophy" back to Japan. Yone Minagawa, who lives in the same area, is 114 and holds the title of world"s oldest woman. Japan"s population of the centenarians is the largest in the world. Most of the 28,000 Japanese who have made it beyond 100 are women and the highest concentration of the very elderly is in the southern part. The area around Hiroshima and the island of Okinawa are especially rich in former "world"s oldest" title holders. The number of centenarians has risen 160-fold since records began in the 1960s. Although Japan is proud of its record-breaking longevity, the success of Mr. Tanabe comes as the country is running short of ideas for how to solve its ageing crisis. With the fertility rate still at record lows, government and private sector efforts to stimulate the birthrate have met with little success. As the number of children decreases, the future welfare burden for working-age Japanese may become intolerably large. It is suggested in the last paragraph that _____.
