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 (与受伤相关的) deaths among children happen 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 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 (运动) 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.

● Wear a life jacket (救生衣) when on a boat or doing water sports.

● Obey all traffic laws.
