A dog, it is said, is a man's best friend. Put a dog, a kid and a book together, and you have a struggling reader's best friend.

    The therapy dogs of R.E.A.D. – Reading Education Assistance Dogs – have been helping children improve their reading skills since 1999, when Intermountain Therapy Animals (ITA) began the program in Salt Lake City, Utah.

    Today, tens of thousands of R.E.A.D. teams – dogs and their owners – volunteer to spend time with youngsters in schools and libraries across the United States and around the world. The idea is that sharing a book with a nonjudgmental (不带评论的) partner encourages students' confidence and helps develop a love of reading.

    Izzy, a Havanese therapy dog, is a regular visitor to Public School 57 in East Harlem, New York. Students meet him in the library, pick out a book and sit down on the carpet. Izzy snuggles (依偎) up to them and gets ready to hear a story.

    “I love reading to Izzy because he listens to me, and he doesn't make fun of me when I make a mistake,” says third-grader Aelane Vasquez. The 9-year-old, whose parents are from Mexico, is one of 15 Latin-American students at the school who were selected for the program.

    “All the students that we work with in the R.E.A.D. program were behind reading levels at the beginning of the year,” Bridget McElroy, who teaches English as a Second Language, explained. “Now most of them have reached the average level, if not above it.” That's important, because achieving proficiency (熟练) in reading is vital for kids to succeed. Studies have shown that students who can't read at grade level by the end of third grade are four times less likely to graduate high school by the age of 19.

    The R.E.A.D. teams from New York Therapy Animals work with 175 kids at Public School 57 and nine other schools.

    McElroy said she sees a marked difference in Aelane and her classmates, and not just in study. “Not only do the kids have time to practice reading, what we are really seeing is that they are excited to read and practice even when Izzy is not here,” she said.

    It is hardly surprising that clothing manufacturers (生产商)follow certain uniform standards for various features(特征)of clothes. What seems strange, however, is that the standard adopted for women is the opposite of the one for men. Take a look at the way your clothes button. Men's clothes tend to button from the right, and women's from the left. Considering most of the world's population—men and women—are right-handed, the men's standard would appear to make more sense for women. So why do women's clothes button from the left?

    History really seems to matter here. Buttons first appeared only on the clothes of the rich in the 17^th century, when rich women were dressed by servants. For the mostly right-handed servants, having women's shirts button from the left would be easier. On the other hand, having men's shirts button from the right made sense, too. Most men dressed themselves, and a sword drawn from the left with the right hand would be less likely to get caught in the shirt.

    Today women are seldom dressed by servants, but buttoning from the left is still the standard for them. Is it interesting? Actually, a standard, once set, resists change. At a time when all women's shirts buttoned from the left, it would have been risky for any single manufacturer to offer women's shirts that buttoned from the right. After all, women had grown so used to shirts which buttoned from the left and would have to develop new habits and skills to switch. Besides, some women might have found it socially awkward to appear in public wearing shirts that buttoned from the right, since anyone who noticed that would believe they were wearing men's shirts.

    BEIJING, China —Pollution in China remains very serious as the country's rapid economic growth brings new environmental problems, a minister said Saturday.

    Vice Environment Minister Zhang Lijun said China has made progress on environmental protection, but admitted that its rapid economic growth over the past decade has had a negative effect on the environment.

    "Our rapid economic development has continuously brought our country new environmental problems, particularly dangerous chemicals, electronic waste and so on. These environmental pollutants (污染物) bring new problems and affect human health," Zhang told a news conference.

    He said that emissions(排放)of traditional pollutants remain high and some areas have failed to meet government standards.

China has pledged to continue reducing emissions this year of three key air pollutants— ammonia nitrogen, sulfur dioxide and nitrogen oxide. The government has also promised to bring down demand for chemical oxygen—a measure of water pollution by l.5 percent from the 2010 levels.

    In the last five years, there were 912 "environmental emergencies" involving heavy metal pollution, including several well-publicized instances of mass contamination, Zhang said. Thousands of children were affected by lead poisoning in several provinces in 2009 and 2010 because they lived near metal smelters or battery factories.

    The minister noted that rapid development in the next five years would increase the need for China to improve environmental protection and shift to a more sustainable(可持续的) model of economic development from its dependence on industries which consume huge quantities of energy.

    China is focusing on clean energy, including solar, wind and nuclear power, as one way to reduce its dependence on coal, which generates three-quarters of its electricity and is also used for winter heating in northern cities. China also hopes the strategy will reduce its demand for oil and gas and increase economic growth and jobs.

    Zhang told reporters there was no plan to adjust China's overall strategy for nuclear development but he said Beijing will learn lessons from Japan after a violent earthquake resulted in a radioactive leak(放射能泄露).

    "Some lessons we learn from Japan will be considered in the making of China's nuclear power plans," he said. "But China will not change its determination and plan for developing nuclear power."

    Three-quarters of the world's coffee farms destroy forest habitat to grow coffee in the sun and typically use harmful pesticides (杀虫剂) and chemicals that poison the environment. When forests disappear, migratory (迁徙的) songbirds disappear, too. In order to deal with severe population and habitat loss, Smithsonian scientists created the Bird Friendly certification.

    Bird Friendly coffees are shade-grown, meaning the coffee is planted under trees, rather than on the land that has been cleared of all other plants. Coffee experts say shade-grown coffees taste better, because the beans ripen slower than coffee grown in the full sun, resulting in a richer, more complex flavor. Bird Friendly certified coffees grow under bio-diverse shade that provides habitat for migratory songbirds and other wildlife, stores carbon and fights climate change. Bird Friendly coffees are also certified organic, meaning they are grown without pesticides, which is better for people and for the planet.

    Bird Friendly producers can also earn more for their crops. The wood and fruit trees on shade coffee farms provide farmers with additional income. Every cup of Bird Friendly coffee purchased rewards these farmers with a little more money for being good stewards of the environment and encourages them to continue conserving Bird Friendly habitat.

    Buying Bird Friendly supports the Smithsonian Migratory Bird Center's conservation research aimed at understanding and protecting your feathered friends. You can purchase Bird Friendly certified coffees around the world and protect wildlife and habitat with every cup. Find a store or cafe near you, or better yet, have it shipped to your door when you order online.

    Although toys packaging says it's educational, it doesn't make it so. That's the finding from a new study in JAMA Pediatrics that found some toys being marketed as language promoters got in the way of learning.

    Research shows that for kids to understand, speak and eventually read or write a language, they need to hear it - lots of it. And it's never too early for parents and to caregivers to get talking. That explains the booming industry in talking electronic toys that claim to help kids learn language.

    Professor Anna Sosa, of Northern Arizona University, led the study and says she gave families three different kinds of toys to play with: books, traditional toys like humble blocks and a shape sorter, and electronic toys. Sosa says she picked those toys because they are advertised in their packaging as language-promoters for babies between the ages of 10 and 16 months.

    "We had a talking on farm-animal names and things," Sosa says of the electronic toys. "We had a baby cell phone. And we had a baby laptop. So you open the cover and start pushing buttons, and it tells you things. The parent-child couples were asked to play separately with each type of toy over the course of three days."

    "When there's something else that's doing some talking, the parents seem to be sitting on the sidelines and letting the toy talk for them and respond for them," Sosa says. "That's bad because the best way a toy can promote language in infants and toddlers is by stimulating interaction between parent and child. There's simply no evidence that a young child can learn language directly from a toy. It isn't responsive enough. It isn't social."

    As for the other toys, traditional blocks and puzzles stimulated more conversation than the electronic toys, and books outscored them all. But don't underestimate the humble block. While traditional toys fell short of books in interaction quantity, Sosa notes, they kept pace in terms of quality.
