改点英语小错误.一分钟就可完成,Kindness is a bridge what can communciate with each others.May be strangers can help you when you get into trouble.哪里错了?

Kindness is a bridge that can communciate with each others.May be strangers can help you when you get into troubles.

Kindness is a bridge THAT can communciate with each others.Maybe strangers can help you when you get into trouble

Kindness is a bridge that/ which can communciate with each others.Maybe strangers can help you when you get into trouble.
用that或which都可, that和which可省略, 因为这里关系代词当受词.

第一句中的WHat 错 应该 改成which

原文错误太多.
重新说一下吧.
Kindness is a bridge for communication between two two strangers.And it is very likely that strangers can help you when you get into trouble.
