阅读下列材料:

材料一  欲观周之所以定天下,必自其制度始矣。周之制度之大异于商者,一曰立子立嫡之制,由是而生宗法及丧服之制;并由是而有封建子弟之制、君天子臣诸侯之制。……其旨则在纳上下于道德,而合天子、诸侯、卿大夫、士、庶民,以成一道德之团体。周公制作之本意实在于此。

——王国维《殷周制度论》

材料二  春秋时犹宗周王,而七国则绝不言王矣;……春秋时犹论宗姓氏族,而七国则无一言及之矣;春秋时犹宴会赋诗,而七国则不闻矣;春秋时犹有赴告策书,而七国则无有矣。邦无定交,士无定主,此皆变于一百三十三年之间,史之阙文,而后人可以意推者也,不待始皇之并天下,而文、武之道尽矣。

——《日知录》

材料三  周文武所封子弟同姓甚众,然后属疏远,相攻击如仇雠,诸侯更相诛伐,周天子弗能禁止。今海内赖陛下神灵一统,皆为郡县,诸子功臣以公赋税重赏赐之,甚足易制。天下无异意,则安宁之术也。

——《史记·秦始皇本纪》

材料四  郡县制取代分封制的必然结果就是贵族制让位于官僚制。官僚制是顺应中央集权和皇权制的需要而产生的一种新的组织形式和管理体制。……在官僚制时代,不管是旧贵族、新贵族,还是新兴的士人阶层,都必须通过任命,转化为官僚,才能成为政体的直接参与者。从这个意义上说,贵族从分封制下的社会政治阶层转化成了郡县制下的社会阶层。成为官僚的贵族便不再具有封地主人和天子臣属的双重身份,而仅仅只有天子臣属的一种身份。

任务型阅读

    I had an experience once which taught me something about the ways people made a bad situation worse by blaming themselves. One January, I officiated (主持) at two funerals for two elderly women.____At the first home, the son of the deceased (已故) woman said, “If only I had sent my mother to Florida and gotten her out of this cold and snow, she would be alive today. It's my fault that she died.” At the second home, the son said, “If only I had not insisted her going to Florida, she would be alive today.____ It is my fault.”

    When things don't turn out as we would like them to, we tend to assume that had we done things differently, the story would have had a happier ending. Any time there is a death, the survivors will feel guilty. Because the course of action they took turned out bad, they believe that the opposite course, for example, keeping mother at home, would have turned out better.____

    There seem to be two elements involved in our readiness to feel guilty. The first lies in our belief that the world makes sense—there is a reason for everything that happens.

    The second is the thought that we are the cause of what happens, especially the bad things that happen.____A baby comes to think that the world exists to meet his needs, and that he makes everything happen in it. He wakes up in the morning and calls the rest of the world to its tasks.____When he is hungry, people feed him, and when he is wet, people change him. Very often, we do not completely abandon that childish thought that our wishes cause things to happen.

A. That long airplane ride was more than she could take.

B. After all, how could it have turned out any worse?

C. Life and dead is an unsolved mystery.

D. The roots of this feeling may lie in our childhood.

E. He cries, and someone comes to attend to him.

F. Both died a natural death.

G. They believe that they are responsible for what has happened.
