    Teens and younger children are reading a lot less for fun, according to a Common Sense Media report published Monday.

    While the decline over the past decade is steep for teen readers, some data in the report shows that reading remains a big part of many children's lives, and indicates how parents might help encourage more reading.

    According to the report's key findings, "the proportion (比例) who say they 'hardly ever' read for fun has gone from 8 percent of 13-year-olds and 9 percent of 17-year-olds in 1984 to 22 percent and 27 percent respectively today."

    The report data shows that pleasure reading levels for younger children, ages2-8, remain largely the same. But the amount of time spent in reading each session has declined, from closer to an hour or more to closer to a half hour per session.

    When it comes to technology and reading, the report does little to counsel(建议)parenst looking for data about the effect of e-readers and tablets on reading. It does point out that many parents still limit electronic reading, mainly due to concerns about increased screen time.

    The most hopeful data shared in the report shows clear evidence of parents serving as examples and important guides for their kids when it comes to reading. Data shows that kids and teens who do read frequently, compared to infrequent readers, have more books in the home, more books purchased for them, parents who read more often, and parents who set aside time for them to read.

    As the end of school approaches, and school vacation reading lists loom(逼近)ahead, parents might take this chance to step in and make their own summer reading list and plan a family trip to the library or bookstore.

    When Shakespeare was twenty-one, he went to London, a very interesting place, to try his fortune.

    There was the famous London Bridge and St. Paul's Cathedral, and palaces and markets and long streets full of shops.

    Then, too, there were the daily crowds where could be seen people from all over the world. Knights, scholars and the highwayman (拦路强盗）or thieves, who had been infamous for their clever robberies, passed by each other.

    Here, also, were noblemen dressed in gold, from Italy and Spain and France; slaves from Spanish America, sea captains and ministers, soldiers and servants—all held by chances or interests within the gray walls which circled London, and whose gates gave welcome to as strange a crowd as could be found in the world.

    Into this curious crowd came Shakespeare, quick to see and eager to learn. And before long all these strange sights were as familiar to him as the faces of his own town's residents. Each one told its story to him so plainly that, as before he had learned the secrets of the fields and woods, so now he learned men and men's interests that make up the great world.

    And he learned these lessons so well that when he came to write his plays, he made such use of them as no writer ever made before or since; for it is the use of this knowledge of the world, combined with his own genius, that makes Shakespeare the greatest dramatist that has ever lived.

Dear Bobby Brune,

    Children learn best when they're having fun. “Jungle Gym Jimmy” is an article for parents and children that teaches playground safety and shows how simply playing can promote good health and fitness. The tips are given through the funny voice of the “tour guide” on the playground, seven—year-old Jimmy. By listening to Jimmy, children learn how to use the equipment safely and how to get the most fun out of a day on the playground.

    As a Kid Talk subscriber for the last seven years. I am very familiar with your publication, and feel this article would be a positive addition to the “I Can Do It” section of the magazine. The article is 2, 114 words, and has been divided into categories in a way that holds children's interest. Being a mother of four children and using our home as a meeting place for most of the neighborhood, I've had the opportunity to test and confirm that the fun and easy “exercises” offered here are not only effective but are lots of fun for kids.

    I've been writing children's stories and articles for several years, and have had many of my stories published in Kids Know Best, a small newspaper that the Cinder Primary School publishes each month. I'm also a founding member of the “Right On Baby” editorial group which publishes a monthly e—zine for parents with newborns, and I'm a contributing editor to “Write Now,” an online site that teaches creative writing.

    Thank you for your time.

Sincerely,

Claudia Parker

    The Earth is facing a climate crisis, but it's also getting greener and leafier. According to new research, the rise is largely due to China and India.

    A study by National Aeronautics and Space Administration (NASA), based on extensive satellite photographs and published in the journal Nature Sustainability, has revealed that the two countries with the world's biggest populations are also responsible for the largest increase in greenness.

    Since 2000, the planet's green leaf area has increased by 5 percent, or over 2 million square miles. That's an area equivalent to the sum total of the Amazon rainforests, NASA says. But researchers stressed that the new greenery does not neutralize deforestation and its negative impacts on ecosystems elsewhere.

    A third of the leaf increase is thanks to China and India, due to the implementation of major tree-planting projects alongside a vast increase in agriculture.

    Using the data from a NASA sensor, researchers discovered that China is the source of a quarter of the increase in green leaf area, despite possessing only 6.6 percent of the world's vegetated area (植被区). Forests account for 42 percent of that increase, while croplands make up a further 32 percent. China's increase in forest area is the result of forest preservation and expansion programs, NASA said, established to fight against the impacts of climate change, air pollution and soil erosion (水土流失). India has contributed a further 6.8 percent rise in green leaf area, with 82 percent from croplands and 4.4 percent from forests.

    Rama Nemani, a co-author of the study and a researcher at NASA's Ames Research Center, said in a statement, "When the greening of the Earth was first observed, we thought it was due to a warmer, wetter climate and fertilization from the added carbon dioxide in the atmosphere, leading to more leaf growth in northern forests, for instance." "Now, with the data that lets us understand the phenomenon at really small scales, we see that humans are also contributing," Nemani said. "This will help scientists make better predictions about the behavior of different Earth systems, which will help countries make better decisions about how and when to take action."

    Thomas Pugh, a professor at the University of Birmingham's School of Geography, Earth and Environmental Sciences, said the NASA report expands scientists' understanding of the causes behind global greening. But he also cautioned that a direct line cannot be drawn between an increase in global greening and a decrease in negative impacts of climate change.

    Being able to land safely is a critically important skill for all flying animals. Comparatively speaking, ground living animals face no particular challenge when they need to stop running or crawling, while flying animals move at much higher speed, and they must be careful about how they land. Hitting the ground, or even water, at full flight speed would be quite dangerous. Before touching down, they must decrease their speed in order to land safely. Both bats and birds have mastered the skill of landing, but these two types of flyers go about it quite differently.

    In the past it was believed that, in terms of flying mechanics, there was little difference between bats and birds. This belief was based only on assumption, however, because for years nobody had actually studied in detail how bats move their wings. In recent years, though, researchers have discovered a number of interesting facts about bat flight. Bats are built differently from birds, and their wings are made up of both their front and hind limbs (肢体). This makes coordinating (协调) their limbs more difficult for bats and, as a result, they are not very good at flying over longer distances. However, they are much better at the ability to adjust themselves: a bat can quickly change its direction of flight or completely reverse it, something a bird cannot easily do.

    Another interesting characteristic of bat flight is the way in which bats land-upside down! Unlike birds which touch down on the ground or on tree branches, bats can be observed flying around and then suddenly hanging upside down from an object overhead. One downside to this landing routine is that the bats often land with some force, which probably causes pain. However, not all bats hit their landing spots with the same speed and force; these will vary depending on the area where a bat species makes its home. For example, a cave bat, which regularly lives on a hard stone ceiling, is more careful about its landing preparation than a bat more accustomed to landing in leafy treetops.

    When you think back to the blackboard from your school days, what color is it? Chances are that it's green. So what's up with the name? Originally, blackboards were really black. Before wall-sized blackboards existed, late 18th-century students used their own mini boards made of slate (石板) or painted wood, according to Concordia University, Those first boards were, in fact, black, and they paved the way for the larger ones.

    In 1800 when a Scottish headmaster named James Pillans wanted his students to draw maps, the students couldn't draw the maps their teacher wanted on their tiny boards, so Pillans put several slates together to create a large board. Problem solved! From there, the idea spread quickly as teachers could finally show a concept to the whole class at one time. By 1815, the massive writing spaces were common enough to earn their own name: blackboard.

    The color change came in the 1960s when companies sold, steel plates, coated with green enamel (漆) instead of the traditional dark slate. The new material was lighter and less fragile than the first blackboards, so they were cheaper to ship and more likely to survive the journey. Teachers weren't complaining either. After all, the new "greenboards" made the chalk powder easier to erase. Plus, the enamel left less of a glare and the color was nicer to look at. At that point, people started using the word "chalkboard "as a more accurate descriptor, but "blackboard" still stuck around.
