idealistic
Of,relating to,or having the nature of an idealist or idealism.
If you describe someone as idealistic,you mean that they have ideals,and base their behaviour on these ideals,even though this may be impractical.
这是两本字典关于idealistic的解释
而practicle更侧重于现阶段就可以达到的一个不是非常难的目标
可以理解为前者是梦想,而后者是目标
我倾向于前者,可以写伟人为了远大的理想而奋斗造福人类,比如林肯解放黑奴,（马丁路德金）,海伦凯勒,mother terasa 等等,为人类事业现身的杰出代表.
我六月考啊.紧张ing.
