Researchers found that compared with teens who spent much of their free time in front of TV sets, those who were physically active often had higher self-respect, better grades and were less likely to have risky behavior like taking drugs, smoking, or drinking．The findings, based on a national survey of nearly 12,000 middle and high school students, were published in a journal．

       "Across the board, children who engaged in any kind of activity were belier off than kids who watched a lot of TV," said study co author professor Penny Gordon Larsen of the University of North Carolina．

       Other studies have linked certain content of television programs, such as violence and sex, to children's behavior．But beyond this issue, Gordon-Larsen said that kids who spend hours watching TV "miss opportunities" to develop skills, learn teamwork and have other experiences that their more active peers benefit from．

       That doesn't mean, however, that kids have to be on the football team． The study found that some activities like skating and skateboarding——which adults sometimes frown upon——were also related to better self respect and less risk taking．

       That skaters were better behaved than TV watchers might come as a surprise to some adults who consider these teens to be bad, according to Gordon-Larsen．Skateboarding is forbidden in many public areas, and some communities oppose building skating parks．But if kids who like to skate have nowhere to do it, "it's a shame," said Gordon-Larsen．

       Not only should parents encourage their kids to engage iii the physical activities they enjoy, she said, but schools and communities should also do more to create opportunities for children to be active．

Can you understand the beginning of this essay? “My smmr hols wr CWOT．B4．we usd 2go2 NY 2C my bro, his GF & 3 kds FTF.”

    The Scottish teacher who received it in class had no idea what the girl who wrote it meant． The essay was written in a form of English used in cell phone text messages．Text messages(also called SMS)through cell phones became very popular in the late 1990s．At first mobile phone companies thought that text messaging would be a good way to send messages to customers，but customers quickly began to use the text messaging service to send messages to each other．Teenagers in particular enjoyed using text messaging，and they began to create a new language for messages called “texting”.

   A text message is limited to 160 characters，including letters，spaces，and numbers，so messages must be kept short．In addition，typing on the small keypad of a cell phone is difficult，so it's common to make words shorter．In texting；a single letter or number can represent a word，like“r”for“are，” “u”for“you，”and“2”for“to．”Several letters can also represent a phrase，like“10l”for“laughing out loud．”Another characteristic of texting is the leaving out of letters

in a word，like spelling“please” as“pls．”

  Some parents and teachers worry that texting will make children bad spellers and bad writers. The student who wrote the essay at the top of this page said writing that way was more comfortable for her．(The essay said，“My summer holidays were a complete waste of time． Before，we used to go to New York to see my brother, his girlfriend，and their three kids face to face．”)

   Not everyone agrees that texting is a bad thing．Some experts say languages always develop，and this is just another way in which English is changing．Other people believe texting will disappear soon．New technology for voice messages may soon make text messages a thing of the past．

Nutrition influences not only students' grades at school but their growth and development. Improper nutrition is one of the causes of childhood obesity. What can you do to help your child avoid childhood obesity?

My first piece of advice is to look in your fridge. What are you buying at the grocery store? Think about it: if you don't buy junk food or snacks, your kids won't eat them at home. Now if you're like me — both of your kids are at school, you'll know you can't police them every second of the day. This is the time when you'll need to talk to your children about their food choices. If you don't know the right food choices, there are so many free resources on-line to guide you.

Try new things. I was very surprised to find out my 4-year-old daughter likes balsamic vinegar — she calls it the "black sauce". She likes to have it with tomatoes and cucumbers. You just never know what your kids might like.

Don't get stressed if you can't always prepare something healthy. You may sometimes leave the house and forget to take something out for dinner, or you are running late and there's no time to cook before you have to take one of the kids somewhere. However, you can still make healthy choices while dining out. Many of the fast food restaurants offer fruit and milk instead of soda. I like to buy organic frozen pizzas from the organic market — for a quick dinner solution(解决办法). All the ingredients are natural. What I do is to serve the pizza with something raw: lettuce, cucumbers, tomatoes, or fruit to try to give the kids something healthy with that meal.

In closing, take baby steps. Don't try to change your family's eating habits in one go, or you'll go nuts.
