最近要做一个关于社交网络的好处和坏处的演讲，最后要问观众几个问题大家来讨论，大家帮我想想可以问什么

As we all know ,everything has two sides .
SNS gives us a platform to know more friends ,and it is convinient for us to communicate with others .As it is a virtual world,we can talk with all kinds of people .What's more ,there is no need to worry about what we should say and what we shouldn't .
On the other hand ,we rely on SNS so much in our life ,we will lose some opptiunities to commnicate with people around us ,for example ,our friends,our teachers ,our parents and so on .Importantly ,we maybe become silent ,dont want to say a word in the real world .

你可以问：很多人利用社交网诈骗，你们相信社交网吗
