bystanders

基本解释

Dear Bystanders: You are doubtless not the only one wondering.
亲爱的旁观者：有这个疑惑的肯定不止你一人。
But in the confusion there were some modest signs of civic heroism, of bystanders who did not just stand by.
然而在混乱局面也有一些表现英勇的市民英雄，他们不只是站在隔岸观火的旁观者。
For example, in a situation in which several bystanders need to band together to overwhelm a perpetrator, they will be more likely to act collectively than to act alone.
例如, 就有这样一种情况，在只有几个旁观者需要联合起来才能压倒一个罪犯的情况下, 他们就可能会更多地采取集体行动。

"And a lot of these bullying prevention and intervention programs that focus on bystanders have been shown to be the effective programs because they focus on changing that bystander behavior.
So instead of watching bullying take place or joining in with the bullying, these programs teach bystanders how to stand up and be supportive of the kids who are being victimized and to say 'You know we don't do that here, we don't engage in those behaviors.'" Professor Swearer advises parents and teachers to try to get children to talk to them about being bullied.
Since the protests began two months ago, more than 30 people have died - protesters,security personnel and bystanders, and more than 1,000 injured.

The other victims were children, co-workers, or other innocent bystanders caught in the cross-fire.
