Children aged 3 to 4 years old use a tablet for over an hour a day.
3到4岁的儿童每天使用平板电脑超过一个小时。
2Why might parents need to set rules for their children's electronic device usage?
Parents need to set rules because children are using electronic devices more and more, and some spend many hours on them, even at night. This suggests a need for boundaries to manage usage.
3The article mentions that there is 'no ideal limit' to using electronic devices. What can we infer about the nature of setting limits for children's device use?
We can infer that what is considered an 'ideal' limit might vary greatly depending on the child, family, and circumstances. Therefore, instead of a universal perfect limit, the focus should be on managing usage and keeping it at a reasonable level.
