五、阅读理解
Many children spend a lot of time watching or playing with electronic media — from televisions to video games, computers and other devices(设备).
So, it is natural that parents should wonder about the time children spend looking at a TV or computer screen. Americans say "screen time" when they talk about any time children spend in front of an electronic device.
Perhaps parents can stop worrying so much about screen time, at least for older boys and girls. The American Academy of Pediatrics(AAP) listed several suggestions for parents and child care workers. Here are some of the suggestions.
Avoid digital(数字的)media use in children younger than 18 to 24 months.
For children aged 18 to 24 months, avoid letting the child watch the media alone.And avoid using the media as a way to comfort your child.
For children two to five years of age, allow one-hour screen time on "high-quality(质量) programming" a day and watch it with your child.
For children aged 6 and older, don't spend too much time using the media. Also, make sure that screen time does not take the place of healthy sleep, exercising, doing homework and other activities.
Make sure to have media-free time together in a family, such as dinner or driving. Also make some areas of the home media-free. Turn off your child's electronic devices an hour before bedtime.
