就是说,我们一般从与自己意见不统一的人那儿学到知识,而不是意见相同的.
可以先从idea入手,说People have varied ideas.Knowledge comes from these ideas.然后说Knowledge是可以分享借鉴的.If I share an apple with a friend,each of us get half of the apple.But knowledge is something that won't get deducted during the process of sharing.知识在分享的过程中是不会减少的.When we share our ideas,we could learn more knowledge.这里就转到意见统一于不统一的问题上.如果一群人意见一样,那当然不可能学到新的知识.We could only learn new ideas from people who disagreed with us.They opened our eyes to things we've never thought about and showed us new methods to tackle new problems.等等.
如果还有问题,可以写站内消息给我.
