北大自主招生试题及答案 2008北京大学自主招生语文试题及答案 一共五大题。 一、写出一个四字短语，要求：偏旁相同。 二、用十个字写一句语义明确的话，要求：声母都是卷舌音，即zh,ch,sh,ri. 三、用文言写一段话，字数50以内。要求：至少出现三个“之”，每个之的意思用法都不相同。 四、默写一首五言律诗。再在每句适当的地方添加两个字，使之成为一首七言绝句。意境不必相同。 五、某官员贪污腐败被人检举，在单位的职工大会上作了检讨。请你模拟想象该官员的心理与口气，写一份检讨书。要求：检讨看似深刻，实际上毫无悔改之心，堆砌词藻，敷衍了事。字数600-700。 参考答案： 1、江河湖海波涛汹涌汹涌澎湃魑魅魍魉琴瑟琵琶 2、这是成人日，仍属正常处。（怎么说怎么别扭） 3 、（1）本日，百数人齐聚京师之考场，为大学之自主招生，全国瞩目之。有人捧卷，久之，叹息搁笔。（就地取材。第一个“之”是“的”。第二个是“的”。第三个是代词。第四个是音节助词。） （2）翌日，各路英雄好汉齐聚长春大学之综合楼，摩拳擦掌，跃跃欲试。忽闻一兄台曰：科举考试，听之任之，如是而已。呜呼，真英雄耳！ 4、春晓
春眠不觉晓，处处闻啼鸟。夜来风雨声，花落知多少。 悠悠春眠不觉晓，时时处处闻啼鸟。漫漫夜来风雨声，家家花落知多少。 5、这个题有点怪，好像不教人学好。为什么要让学生写这种假惺惺的文章？ 人活着是为了生活快乐幸福，我却把生活当成了战场。我的生活主旋律是不满足也不幸福，因为贪婪占有的心是永远满足不了的，永远体验不到真正的幸福，永远在苦苦地追求更大的权力、更高的地位、更多的金钱，在恶性循环中耗尽生命之能。 回想我没有出事前，常常感到疲惫不堪，暴躁易怒，匆忙急躁，活得很累。一年来我反复思考这个问题，寻找原因。如今我感到，最根本的一点，是因为把自己看得太重要了，把权力、地位、金钱看得太重要了。总以为自己比别人强，总想得到更多人的尊重羡慕，总想得到更大的名声；总怕自己的自尊和面子受到伤害；总想得到更大的权力、更高的地位、更多的财富。按常理，追求这些很正常，但我太过分了、扭曲了、变态了。一个目标刚实现，立刻又有了新的目标，马不停蹄，费尽心机，精疲力尽、暴躁易怒。 我现在感到，追求事业首先不应有贪婪占有思想，应当客观根据自身的条件、能力，以平和的心态做事，要把做事本身作为目的，把过程作为目的。 在这种拜金主义思想的支配和影响下，金钱左右了我的价值取向、思想行为，使我失去了宝贵的自由。现在我知道，与自由相比，金钱一文不值。这种动机与结果的关系，细想让人感到真是莫大的讽刺。每个人都希望拥有幸福，但拜金主义不会给人带来幸福，只能使人走向贪婪。贪婪的人永远不满足，因此，可能抢占、囤积了许多财物，但精神永远是空虚不幸福的。我曾以为可以通过追求权力、地位、财富使自己获得幸福，没想到成了没有自由的最不幸福的人。 考生乙答案（回忆版） 1 魑魅魍魉 2 忍失人生志，执之只是痴
