6、船来代替大秤，曹冲想：造大秤可不容易，不如用船来代替大秤，因为船能装很重很重的东西；即使造了大秤，也没有人因为船能装很重很重的东西；即使造了大秤，也没有人能提得起来，那就用水的浮力代替人的力气。能提得起来，那就用水的浮力代替人的力气。读读官员们提出的称象的方法，联系曹冲的办法，说说他的办法妙读读官员们提出的称象的方法，联系曹冲的办法，说说他的办法妙就妙在哪里？就妙在哪里？曹冲用心听别人的议论，积极动脑筋想办法。曹冲用心听别人的议论，积极动脑筋想办法。曹冲善于观察和学习，知识丰富，知道船在水里下沉的曹冲善于观察和学习，知识丰富，知道船在水里下沉的程度与重量有关系。具有丰富的知识，肯动脑筋思考问题
