英语作文语法问题（打括号应该改为什么,谢谢啦!）
Staying away from electronic devices
Some students spend much time on electronic devices, such as playing computer games, watching films and so on. I think Eric Schmidt’s advice is very useful.（ I agree his advice. ）In my opinion, having more time to talkface-to-face with their friends and parents（ are all ）very important. Of course, playing computers games can also relax ourselves.（So everything is moderate.）
答
I agree with him is So everything should be moderatefriends，parents不是复数吗？为什么用is呢？不懂！麻烦解释下啦，谢谢咯！这个句子的主语不是friendsparents而是和别人面对面谈话这件事所以还是单数的
