The two-income family has created a generation of latchkey children.

双职工家庭带来了一代脖子上挂钥匙的孩子…

When the parents both work at the restaurant for long hours, their kids generally become latchkey children.

当父母两人都在餐馆长时间的工作时，他们的孩子放学后都要自己开门回家。

Latchkey children often aren't allowed to play outside their homes until their parents get home, so exercise time at school is even more important.

孩子们经常都被锁在家里，不能外出活动，一直到他们的父母回家。所以学校的体育锻炼就尤为重要。

Many children are latchkey kids. Accidents are frequent; we heard of an elementary school student who badly burned himself in a science experiment, with his older brother watching.

很多孩子都是挂钥匙儿童，所以事故不断，我们听说一个小学上在做实验室严重烧伤，而他的哥哥当时就在旁边。
