疑问：2020年考研国家线工商管理硕士分数线有什么变化？

The picture shows us a cultural hotpot,in which contain the“food”from both the domestic and the abroad,from both the ancient and the modern period.At the bottom of the hotpot,a line of words appears,saying,“cultural hotpot—both delicious and nutritious.This picture was used to indicate that culture fusion benefit us a lot.
Nowadays,we are living in a world where one is cross-connected with others highly.That is to say,the development of our nation needs information from all around the world.As an ancient nation with splendid civilization,we also need to learn from westerners while enhancing and glorifying our traditional culture.In the same manner,those foreigners who are interested in our nation will get valuable hints for their nation’s development.Knowing more about the global culture will help people from different countries understand each other better and live with each other peacefully.Only with understanding,the global issues and disputes can be settled in a satisfying way.Just imagine that how horrible it is if each country isolates from others and resists the foreign information.
Of course,advocating culture fusion does not equal to accepting the foreign culture wholly without considering its bad influence.We must admit that each culture has its merits and dregs,which need us to treat them dialectically.

知觉是客观事物直接作用于感官而在头脑中产生的对事物的整体认识。知觉的特性有：知觉的理解性、知觉的选择性、知觉的恒常性、知觉的恒常性。其中知觉的恒常性是指客观条件改变，知觉保持相对不变的特性。分为形状、大小、明度、颜色和方向恒常。形状恒常性：当我们从不同角度观察同一物体时，物体在网膜上投射的形状是不断变化的。但我们知觉到的物体的形状并没有很大的变化，这就是形状恒常性（门从开到关）。大小恒常性：当我们从不同距离观察同一物体时，物体在网膜上成像的大小是变化的，而知觉到的物体的大小却不完全随着距离而变化，它趋向于原物的实际大小（艾姆斯小屋）。明度恒常性：在照明条件改变时，物体相对明度或视亮度却保持不变，这就是明度恒常性（煤球总是黑色的）。颜色恒常性：一个有颜色的物体在色光照明下，它表面的颜色并不受色光照明的影响，而是保持相对不变，这就是颜色恒常性（家具在不同灯光下，颜色保持相对不变）。方向恒常性：指人不随身体部位或视像方向改变而感知物体实际方位的知觉特性（棒框实验）。知觉恒常性的影响因素：视觉线索（各种参照物提供的信息）和知识经验（建立的对客观世界的稳定知觉）。

【精解】沈家本曾经这样评价《宋刑统》：“《刑统》为宋一代之法制，其后虽用编敕之时多，而终以《刑统》为本。”故C项正确。明太祖朱元璋曾经规定，后世子孙不得对《大明律》更改一字，否则以变乱祖制论，因此《大明律》终世不改，故A项是正确答案。唐朝和清朝都曾经对法典进行过更改，故排除B项和D项。
