In the United States and several other countries , 2.5 million children play baseball in an organization called Little League . They play on teams in their hometowns . Their parents and other adults in the community coach or instruct them and serve as umpires（裁判员）to make sure that everyone follows the rules . Local businesses give money for the ball fields and the uniforms . Local teams compete against each other and the winners get to play teams that are more distant . Eventually , the top teams go to the Little League World Series .

    One hundred years after Abner Doubleday invented baseball in Cooperstown , New York , in 1839 , Little League got started in Pennsylvania . Three men started the game for neighborhood boys with a smaller playing field and fewer innings（局）than adult baseball . Little League became popular after World War II when the game spread across the United States . By 1955 it was played throughout North America and within five years it had spread to Europe. Children's baseball really caught on in Japan and Taiwan of China and teams from those areas won the World Series seven out of eight years . After this , the organization tried banning foreign teams from the World Series , but the ban came to an end after one year .

    At first , Little League was only for boys aged nine to twelve . However , in 1974 , the parents of girl baseball players brought a law suit . The courts ruled that Little League had to include both boys and girls . Later Little League added on softball and other games for teenagers up to age eighteen . Occasionally , a Little Leaguer becomes a professional player . For example , Gary Carter went from Little League to play nineteen seasons in the Major Leagues , ten of them as an All-Star player . By and large , youngsters play baseball for fun , but their parents are pround of them .

    Lisa Pina never thought she would need the fire safety training she received during her apprenticeship(学徒期)as a union painter and dry waller(筑墙工). On Friday morning, she was thanking God she had it.

    On Thursday night, while Pina was babysitting her granddaughter, nephew and two nieces in her sister's apartment, she smelled smoke and realized the apartment building was on fire. When her 4-year-old granddaughter Ilean Garcia began saying, “We're going to die, ”she knew she had to act.Pina,39, first sealed the door, and then told all four children to get on the floor. After calling 911, she told the children to start singing and promised them all treats as soon as they reached safety. “I said, ‘OK, we're going to lie down and we're all going to play a game,'” Pina said. “We all started singing our ABCs and 123s.I was just trying to make it fun.” Pina patiently waited, and a few minutes later, Riverside County sheriff's deputies (治安官的助手) arrived. Pina, Ilean,8yearold Gabriel Parga,5-year-old Aubreyana Parga and 4-year-old Meriyah Parga were all trapped on the second floor as flames filled the first story.  Pina did the only thing she could. She opened the window and dropped the children, one-by-one, into the arms of the sheriff's deputies about 15 to 20 feet below. “I just needed to keep the kids calm so they wouldn't be afraid，”Pina said.“I was deathly afraid inside，but I couldn't let them know that.”[Not long after dropping the children out of the window, firefighters arrived with a ladder and rescued her. Ten people were treated at the scene for suffering smoke, but nobody was seriously injured.

    Teenagers who spend hours in front of the television may have a poorer diet as young adults.

    A study, which included nearly 1,400 high school students, found those who watched TV for five hours or more per day had less healthy diets than peers(同龄人) five years later. Why does this happen? Should the parents take any measures?

    On the one hand, people who spend a lot of time in front of the TV, especially teenagers, may snack more, and that may affect their long-term diet quality.

    On the other hand, TV ads for fast food, sweets and snacks tempt teenagers to eat more of those foods. And TV time might also replace exercise time for some kids.

    Lead researcher Dr. Daheia J. Barr-Anderson, of the University of Minnesota in Minneapolis, told Reuters Health a clear correlation between TV time during high school and diet quality in young adulthood. While the heaviest TV viewers were eating the most junk food, those who'd watched less than two hours per day had the highest intake(吸收) of fruits, vegetables, whole grains and high-calcium food. In her opinion, parents should limit and monitor TV viewing.

    As far as I am concerned, children should watch no more than two hours of television per day. And parents should set a good example by eating right, being physically active and curbing their own TV time.

    These days, more and more Chinese people enjoy sending and receiving messages on the phone. It can help them to get the latest news and communicate with friends. But I think I should read more books besides the textbooks, the more, the better. It can open my eyes and improve my language skills. Of course, it also can help me to get good grades. Do you know how to read more and learn more? Here are some tips for you.

    Clear your purpose for reading

    Before you start reading, ask yourself why you are reading this book. Most people read for two main reasons, pleasure or knowledge. Clearing about your reading purpose can not only help you choose the books you really need to read, but also remind you why reading the book is important to you, so you will keep reading and complete the book faster.

    Read only what you are interested in

    No matter what you are reading, it is important to enjoy what you read. Your friends may tell you the books they love, but those books might not necessarily be the ones you enjoy.

    Give up books that you don't enjoy

    You may have chosen books that you are interested in, and they are right to your purpose. But while you are reading them, there may still be some books that you don't enjoy reading. Whenever you realize that you aren't enjoying the book you are reading, give it up. Remember reading shouldn't be a chore (苦差事).

    Set a reading goal

    It is interesting that I read the books borrowed from libraries faster than those I bought. The reason is the books I bought don't have a due date! I don't need to return those books. Having a reading goal helps you work out how much reading you need to do in a week or even a day. Before you read each book, ask yourself what time you need to complete this book by.

    When I was small and my grandmother died, I couldn't understand why I had no tears. But that night when my dad tried to cheer me up, my laugh turned into crying.

    So it came as no surprise to learn that researchers believe crying and laughing come from the same part of the brain. Just as laughing has many health advantages, scientists are discovering that so, too, does crying.

    Whatever it takes for us to reduce pressure is important to our emotional health, and crying seems to work well. One study found that 85 percent of women and 73 percent of men report feeling better after crying.

    Besides, tears attract help from other people. Researchers agree that when we cry, people around us become kinder and friendlier and they are more ready to provide support and comfort. Tears also enable us to understand our emotions better; sometimes we don't even know we're very sad until we cry. We learn about our emotions through crying, and then we can deal with them.

    Just as crying can be healthy, not crying - holding back tears of anger, pain or suffering - can be bad for physical health, Studies have shown that too much control of emotions can lead to high blood pressure, heart problems and some other illnesses. If you have a health problem, doctors will certainly not ask you to cry. But when you feel like crying, don't fight it. It's a natural –and healthy-emotional response.

    The term "crocodile tears" refers to insincere sadness. This term has an etymology dating back several centuries. As early as the fourth century, crocodile tears are referenced in the literature with the meaning of insincere sorrow. It is said that crocodiles weep while eating their hunted animals because they are sad; however, this sadness is not honest.

    The term crocodile tears became widely popular after it was documented in a fifteenth-century book titled The Voyage and Travel of Sir John Mandeville, Knight. A passage from the book reads: "These crocodiles kill men and they eat them weeping."

    As you may already know, crocodilians(鳄目动物) likely feel bad about little—especially feeding. However, the assumption of the crocodile-tears metaphor may be true. In a 2007 paper published in BioScience titled "Crocodile Tears: And they eat them weeping", researchers observed 7 crocodilians in cages during feeding time at a reserve (4 caimans and 3 American alligators). The researchers observed the crocodilians outside of water at feeding stations to better find out whether tearing developed.

    Five of the 7 crocodilians developed something like tears in their eyes before, during or after feeding. The researchers suggest that these crocodile tears occur because a crocodilian hisses (发出嘶嘶声) while it eats, and this hissing forces air through the spaces in the bone behind the nose and out the eye, in the process picking up nasolacrimal secretions (鼻泪管分泌物.)

    In humans, crocodile tears is a medical condition that causes a person to tear up while eating. Crocodile tears typically occur because of a temporary loss of facial control due to damage of the facial nerve. Specifically, when the facial nerve grows again, it does so incorrectly thus resulting in tears during chewing food.
