    Akuapem is in the eastern part of Ghana. The sun there shines all the time. The local people are very friendly and hospitable(好客的). Now let's have a look at how Akuapem people receive a visitor.
    A visitor is often welcomed warmly in a family of Akuapem. After the visitor is welcomed into the house, he is offered a seat and water at the very beginning, because the host assumes that the visitor must have come from a very long journey and need water. If there is a group of visitors, the host will greet the visitors from right to left. And the host shakes only with his right hand, because Akuapem people think the left hand is not clean.
    Next, the visitor is asked how his journey was and why he has come. While the conversation is going on, the wife and the children, especially girls, are preparing food for the visitor. The visitor can choose his favorite food. After the visitor finishes eating, the host and the visitor go on with their conversation. Usually this is short one because the visitor is getting ready to say goodbye.
    When the visitor is leaving, he is often given some food. He is also accompanied(陪伴) by one of the children to the nearest station. The child who accompanies the visitor will not come back home until the visitor leaves safely.
    Whether he is a close friend or just a stranger, this is always how friendly Akuapem people receive a visitor.

材料一：在春秋战国时期，随着社会生产力的提高，西周的制度发展程度过低，无法更多的满足新兴地主阶级的发展需求。他们力求改变现状。试图获得更多的经济、政治、文化地位。呼唤建立新的社会，从而推动了百家争鸣的产生与发展。

——据李静、萧红恩《百家争鸣与文艺复兴的历史比较》

材料二：文艺复兴主要是一场文化运动。强调对希腊罗马经典的研究以及对个人成就的赞扬。它最早出现在14世纪的意大利。随后遍及欧洲大地，成为l4世纪摧毁中世纪旧结构的“灾难”。……她将欧洲从中世纪引向了近代世界。

——丹尼斯·谢尔曼乔伊新•索尔兹伯里《全球视野下的西方文明史》

材料三：新文化运动期间，陈独秀等人指出：“要拥护那德先生，便不得不反对孔教、礼法、贞节、旧伦理、旧政治。要拥护那赛先生，便不得不反对旧艺术、旧宗教。要拥护德先生又要拥护赛先生，便不得不反对国粹和旧文学。”

材料四：（“文革”结束后开始的）这场讨论的内容是，究竟什么是检验真理的标准。这场讨论深层的含义则是要解决中国走什么道路的问题。因此，这是一场关系到中国前途和社全主义命运的大讨论。
