5．Children know that summer is probably the most fun of all seasons．However，experts say it is also the most dangerous，especially，for children aged 14 and under．In its first study of children's safety in the US，the National Safe Kids Campaign （NSKC） found that nearly half of the injury-related （與受傷相關(guān)的） deaths among children happened in summer．
     Experts are not surprised by the study's results．They always know summer is a dangerous season for children．During the summer，children are out of school and spend more time outdoors．They are more likely to get into an accident or be injured．"While we encourage children to be active and spend more time outdoors，they need to understand the importance of safety，"said Everett Koop，an expert of the NSKC．
     To help children stay safe，the NSKC started a"Make it a Safe Kids Summer"campaign during National Safe Kids Week，from May 5 through May 12．Here are some important summer safety tips from the NSKC：
●Always wear your seat belt．
●Make sure there is an adult around when you decide to go swimming．

12．In winter，when the sun hides behind the clouds，everyone feels a bit low．You may be tired and find you want to sleep all the time．What you may not know is：you are suffering from （患有） SAD（季節(jié)性抑郁癥）．
But don't worry-it's normal．Colder temperatures and fewer hours of daylight can steal your energy and put you in a bad mood．

9．How to deal with homesickness
When you sleep somewhere else，like at a summer camp or a friend's house，you know you're there for a fun time．But for some kids，when they are away from home they feel sad．They start to miss their own beds，their own parents，and all the things at home．It's called being homesick（想家的）．Do you want to feel less homesick？Here's how：
Spend more time in doing fun things．The more fun things you do，the less time you'll have to feel homesick．So try to take part in activities and soon you might start to have a good time．
You can make a plan to call your mum or dad．For a night visit，maybe you can call once that night，and again in the morning．In the camp，you might set a regular day and time for a phone call home．You can also send e-mails or short messages to keep in touch （保持聯(lián)系） with family and friends．If you're going to be away for a while，you might even write a letter!When you get in touch with someone，make sure to tell them the fun things you're doing!
Sometimes，just tell someone that you're feeling homesick．This will help you feel better，Maybe you can tell a friend that you feel homesick．And the two of you can do something fun，such as telling jocks．If you're at camp，a camp counselor（顧問） would be a good person to talk to．He or she might have some ideas to help you feel better．
