夏说英语新闻晨读 第508期:电子屏幕对孩子无害?

 本期内容：

There is little evidence screen use for children is harmful in itself, guidance from leading pediatricians says. It says there is no good evidence that time in front of a screen is "toxic¹" to health, as is sometimes claimed. While the guidance avoids setting² screen time limits, it recommends not using them in the hour before bedtime. Meanwhile, a separate study has found that girls are twice as likely to show signs of depressive symptoms linked to social media use at age 14 compared with boys.
