一个伊斯兰激进网站发放了一段据称是阿尔盖达领袖奥萨玛·本·拉登的录音。他呼吁创立新的救助团体以协助穆斯林。周五的信息是近几星期阿尔盖达人物就巴基斯坦境内影响近二千万人的水灾发表的第三次。本·拉登表示应成立新的“资金充裕”的支援机构，研究穆斯林区域的水文以防止未来的洪水灾害。信息显示阿尔盖达正加紧活动，利用因水灾引起的愤怒来寻求支持。信息的真实性没有得到独立证实。

第二个。单从语法上“奥巴马宣布本拉登死亡”那句，第一个和第二个都没有语法错误，但是语言习惯上，第二个更适合。而“美国东部时间5月1日，下午11点35分，奥巴马在白宫突然宣布：基地组织头目本拉登在一次军事行动中被击毙”这句，其他三句狗屁不通，最后一个有为夸张，全用单词来描述时间，这种现象在任何正常情况下都不会发生。第一句是没什么America time(美洲时间），第二也不会有1st of May这种形式。第三句，没什么EST On.....最后一个，我前面说了。

美国总统布什竞选讲演稿(LEHRER: New question, Mr. President. Two minutes. What about Senator Kerry"s point, the comparison he drew between the priorities of going after Osama bin Laden and going after Saddam Hussein? BUSH: Jim, we"ve got the capability of doing both. As a matter of fact, this is a global effort. We"re facing a group of folks who have such hatred in their heart, they"ll strike anywhere, with any means. And that"s why it"s essential that we have strong alliances, and we do. That"s why it"s essential that we make sure that we keep weapons of mass destruction out of the hands of people like Al Qaida, which we are. But to say that there"s only one focus on the war on terror doesn"t really understand the nature of the war on terror. Of course we"re after Saddam Hussein -- I mean bin Laden. He"s isolated. Seventy-five percent of his people have been brought to justice. The killer -- the mastermind of the September 11th attacks, Khalid Sheik Mohammed, is in prison. We"re making progress. But the front on this war is more than just one place. The Philippines -- we"ve got help -- we"re helping them there to bring -- to bring Al Qaida affiliates to justice there. And, of course, Iraq is a central part in the war on terror. That"s why Zarqawi and his people are trying to fight us. Their hope is that we grow weary and we leave. The biggest disaster that could happen is that we not succeed in Iraq. We will succeed. We"ve got a plan to do so. And the main reason we"ll succeed is because the Iraqis want to be free. I had the honor of visiting with Prime Minister Allawi. He"s a strong, courageous leader. He believes in the freedom of the Iraqi people. He doesn"t want U.S. leadership, however, to send mixed signals, to not stand with the Iraqi people. He believes, like I believe, that the Iraqis are ready to fight for their own freedom. They just need the help to be trained. There will be elections in January. We"re spending reconstruction money. And our alliance is strong. That"s the plan for victory. And when Iraq if free, America will be more secure. LEHRER: Senator Kerry, 90 seconds. KERRY: The president just talked about Iraq as a center of the war on terror. Iraq was not even close to the center of the war on terror before the president invaded it. The president made the judgment to divert forces from under General Tommy Franks from Afghanistan before the Congress even approved it to begin to prepare to go to war in Iraq. And he rushed the war in Iraq without a plan to win the peace. Now, that is not the judgment that a president of the United States ought to make. You don"t take America to war unless have the plan to win the peace. You don"t send troops to war without the body armor that they need. I"ve met kids in Ohio, parents in Wisconsin places, Iowa, where they"re going out on the Internet to get the state-of-the-art body gear to send to their kids. Some of them got them for a birthday present. I think that"s wrong. Humvees -- 10,000 out of 12,000 Humvees that are over there aren"t armored. And you go visit some of those kids in the hospitals today who were maimed because they don"t have the armament. This president just -- I don"t know if he sees what"s really happened on there. But it"s getting worse by the day. More soldiers killed in June than before. More in July than June. More in August than July. More in September than in August. And now we see beheadings. And we got weapons of mass destruction crossing the border every single day, and they"re blowing people up. And we don"t have enough troops there. BUSH: Can I respond to that? LEHRER: Let"s do one of these one-minute extensions. You have 30 seconds. BUSH: Thank you, sir. First of all, what my opponent wants you to forget is that he voted to authorize the use of force and now says it"s the wrong war at the wrong time at the wrong place. I don"t see how you can lead this country to succeed in Iraq if you say wrong war, wrong time, wrong place. What message does that send our troops? What message does that send to our allies? What message does that send the Iraqis? No, the way to win this is to be steadfast and resolved and to follow through on the plan that I"ve just outlined. LEHRER: Thirty seconds, Senator. KERRY: Yes, we have to be steadfast and resolved, and I am. And I will succeed for those troops, now that we"re there. We have to succeed. We can"t leave a failed Iraq. But that doesn"t mean it wasn"t a mistake of judgment to go there and take the focus off of Osama bin Laden. It was. Now, we can succeed. But I don"t believe this president can. I think we need a president who has the credibility to bring the allies back to the table and to do what"s necessary to make it so America isn"t doing this alone. LEHRER: We"ll come back to Iraq in a moment. But I want to come back to where I began, on homeland security. This is a two-minute new question, Senator Kerry. As president, what would you do, specifically, in addition to or differently to increase the homeland security of the United States than what President Bush is doing? KERRY: Jim, let me tell you exactly what I"ll do. And there are a long list of thing. First of all, what kind of mixed message does it send when you have $500 million going over to Iraq to put police officers in the streets of Iraq, and the president is cutting the COPS program in America? What kind of message does it send to be sending money to open firehouses in Iraq, but we"re shutting firehouses who are the first- responders here in America. The president hasn"t put one nickel, not one nickel into the effort to fix some of our tunnels and bridges and most exposed subway systems. That"s why they had to close down the subway in New York when the Republican Convention was there. We hadn"t done the work that ought to be done. The president -- 95 percent of the containers that come into the ports, right here in Florida, are not inspected. Civilians get onto aircraft, and their luggage is X-rayed, but the cargo hold is not X- rayed. Does that make you feel safer in America? This president thought it was more important to give the wealthiest people in America a tax cut rather than invest in homeland security. Those aren"t my values. I believe in protecting America first. And long before President Bush and I get a tax cut -- and that"s who gets it -- long before we do, I"m going to invest in homeland security and I"m going to make sure we"re not cutting COPS programs in America and we"re fully staffed in our firehouses and that we protect the nuclear and chemical plants. The president also unfortunately gave in to the chemical industry, which didn"t want to do some of the things necessary to strengthen our chemical plant exposure. And there"s an enormous undone job to protect the loose nuclear materials in the world that are able to get to terrorists. That"s a whole other subject, but I see we still have a little bit more time. Let me just quickly say, at the current pace, the president will not secure the loose material in the Soviet Union -- former Soviet Union for 13 years. I"m going to do it in four years. And we"re going to keep it out of the hands of terrorists. LEHRER: Ninety-second response, Mr. President. BUSH: I don"t think we want to get to how he"s going to pay for all these promises. It"s like a huge tax gap. Anyway, that"s for another debate. My administration has tripled the amount of money we"re spending on homeland security to $30 billion a year. My administration worked with the Congress to create the Department of Homeland Security so we could better coordinate our borders and ports. We"ve got 1,000 extra border patrol on the southern border; want 1,000 on the northern border. We"re modernizing our borders. We spent $3.1 billion for fire and police, $3.1 billion. We"re doing our duty to provide the funding. But the best way to protect this homeland is to stay on the offense. You know, we have to be right 100 percent of the time. And the enemy only has to be right once to hurt us. There"s a lot of good people working hard. And by the way, we"ve also changed the culture of the FBI to have counterterrorism as its number one priority. We"re communicating better. We"re going to reform our intelligence services to make sure that we get the best intelligence possible. The Patriot Act is vital -- is vital that the Congress renew the Patriot Act which enables our law enforcement to disrupt terror cells. But again, I repeat to my fellow citizens, the best way to protection is to stay on the offense. LEHRER: Yes, let"s do a little -- yes, 30 seconds. KERRY: The president just said the FBI had changed its culture. We just read on the front pages of America"s papers that there are over 100,000 hours of tapes, unlistened to. On one of those tapes may be the enemy being right the next time. And the test is not whether you"re spending more money. The test is, are you doing everything possible to make America safe? We didn"t need that tax cut. America needed to be safe. BUSH: Of course we"re doing everything we can to protect America. I wake up every day thinking about how best to protect America. That"s my job. I work with Director Mueller of the FBI; comes in my office when I"m in Washington every morning, talking about how to protect us. There"s a lot of really good people working hard to do so. It"s hard work. But, again, I want to tell the American people, we"re doing everything we can at home, but you better have a president who chases these terrorists down and bring them to justice before they hurt us again. LEHRER: New question, Mr. President. Two minutes. What criteria would you use to determine when to start bringing U.S. troops home from Iraq? BUSH: Let me first tell you that the best way for Iraq to be safe and secure is for Iraqi citizens to be trained to do the job. And that"s what we"re doing. We"ve got 100,000 trained now, 125,000 by the end of this year, 200,000 by the end of next year. That is the best way. We"ll never succeed in Iraq if the Iraqi citizens do not want to take matters into their own hands to protect themselves. I believe they want to. Prime Minister Allawi believes they want to. And so the best indication about when we can bring our troops home -- which I really want to do, but I don"t want to do so for the sake of bringing them home; I want to do so because we"ve achieved an objective -- is to see the Iraqis perform and to see the Iraqis step up and take responsibility. And so, the answer to your question is: When our general is on the ground and Ambassador Negroponte tells me that Iraq is ready to defend herself from these terrorists, that elections will have been held by then, that their stability and that they"re on their way to, you know, a nation that"s free; that"s when. And I hope it"s as soon as possible. But I know putting artificial deadlines won"t work. My opponent at one time said, "Well, get me elected, I"ll have them out of there in six months." You can"t do that and expect to win the war on terror. My message to our troops is, "Thank you for what you"re doing. We"re standing with you strong. We"ll give you all the equipment you need. And we"ll get you home as soon as the mission"s done, because this is a vital mission." A free Iraq will be an ally in the war on terror, and that"s essential. A free Iraq will set a powerful example in the part of the world that is desperate for freedom. A free Iraq will help secure Israel. A free Iraq will enforce the hopes and aspirations of the reformers in places like Iran. A free Iraq is essential for the security of this country. LEHRER: Ninety seconds, Senator Kerry. KERRY: Thank you, Jim. My message to the troops is als Thank you for what they"re doing, but it"s also help is on the way. I believe those troops deserve better than what they are getting today. You know, it"s interesting. When I was in a rope line just the other day, coming out here from Wisconsin, a couple of young returnees were in the line, one active duty, one from the Guard. And they both looked at me and said: We need you. You"ve got to help us over there. Now I believe there"s a better way to do this. You know, the president"s father did not go into Iraq, into Baghdad, beyond Basra. And the reason he didn"t is, he said -- he wrote in his book -- because there was no viable exit strategy. And he said our troops would be occupiers in a bitterly hostile land. That"s exactly where we find ourselves today. There"s a sense of American occupation. The only building that was guarded when the troops when into Baghdad was the oil ministry. We didn"t guard the nuclear facilities. We didn"t guard the foreign office, where you might have found information about weapons of mass destruction. We didn"t guard the borders. Almost every step of the way, our troops have been left on these extraordinarily difficult missions. I know what it"s like to go out on one of those missions when you don"t know what"s around the corner.

WASHINGTON, Oct. 7 (Xinhua) -- The bottom line for the U.S. strategy in Afghanistan is no deep cuts in troop levels, President Barack Obama told congressional leaders. During a session with a bipartisan group of congressional leaders on Tuesday, the president also made it clear that the U.S. mission in Afghanistan would not be narrowed down to just hunting al-Qaida leaders, according to U.S. TV and wire reports Wednesday. Analysts said, based on Obama"s remarks at the meeting, that he seemed to be searching for some sort of middle ground. The president said he wanted to "dispense with the straw man argument that this is about either doubling down or leaving Afghanistan." While leading congressional Democrats said they would support whatever Obama decided, others challenged him about sending more troops. Republicans pressed him to order an escalation without delay. Washington is currently split on the future direction of the Afghan strategy. Top military leaders and opposition Republicans are pressing Obama to act quickly to increase the present 68,000-troop level by as many as 40,000. Meanwhile, senior White House advisors are reportedly pushing back the request for sending large number of additional troops to Afghanistan. Instead, they said, the U.S. should focus on faster military training of Afghan forces, the assassinations of al-Qaida leaders and support for the government of neighboring Pakistan in its fight against the Taliban. As the casualty toll grows and public support for the Afghan war wanes, Obama is carrying out a major strategy review of his Afghanistan policy, which could either lead to more troops being sent or a cutback in the 68,000-strong U.S. force there.

Off the hook啥意思？ Off the hook“摆脱困境”，hook表示“钩子”，off the hook似乎为“摆脱钩子”含义，实际为引申义“摆脱困境，脱身”。 英文释义：used to tell someone to stop and consider carefully their decision or opinion about something: John"s agreed to go to the meeting in my place so that lets me off the hook.约翰同意替我开会，让我终于可以脱身。 Nobody can help you off the hook except yourself .除了你自己，没有人能够帮助你摆脱困境。

Para Para 这种舞蹈的发源地是日本并早於七十年代末期已经开始存在, 但一直未能将此舞蹈发扬到海外. 直到 "90 年代初期, 日本便开始兴起 ParaPara 这种舞蹈, 近乎所有 Disco 也转变成 ParaPara Club; 但直到 "90 年代中期, ParaPara 便开始下滑, 近期日本由知名人士 - 木村拓哉及滨崎步等明星於公开场合甚至於超过一万人的演唱会内教跳 ParaPara, 令各人一起跳 ParaPara Dancing. 令到 ParaPara Dancing 在日本又再次掀起第三次热潮来 , 而一间以出版音乐机为名的 Konami 游戏机厂 , 也藉此诞生了一部名为 ParaParaParadise(PPP) 的音乐跳舞机 . 这部跳舞机采用了红外线感应器来感应玩者的舞姿 , 所以大家可以於这跳舞机上跳出 ParaPara Dancing. 故此大家可以在一些有 PPP 的机铺看到有一大群 ParaPara Dancers 呢! ParaPara 主要的音乐是以 Eurobeat 为主呀 而ParaPara 的音乐种类是 Eurobeat, Eurobeat 是一种来自意大利的跳舞音乐, 已有20年多的历史了. 音乐主要以快速的电子音乐为主, 与 Trance 的格式差不多, 不过 Trance 是以 Beat 为主, Eurobeat 就以曲为主. ParaPara 更是以 Eurobeat 的曲与词而跳出舞蹈. 新一代的 ParaPara 其实ParaPara 於这廿多年来经过不断的改进, ParaPara 又於不同年代不断演变 Style. 近期因为 ParaPara Dancer 以高中女生为主, 故此近期所 hit 的 ParaPara Dancing 亦较为女性化 (当然只是一部份), 但日本有很多男性跳此类 ParaPara 亦相当有型, 但亦不离那首歌的基本动作, 这就是个人风格. 日本的 ParaPara, 香港的文化 在日本, ParaPara 在 Disco 到处可见, ParaPara Disco 每晚也最少有 300 人以上一起跳, 虽然香港亦开始有 Disco 定期举行 ParaPara Disco, 但始终在香港进出 Disco 并不为一般人所认同，因此一众热心参与的人士都会在街头四处寻找地方玩乐，假若你在 2000 年年尾至 2001 年年初期间的星期六晚上曾来过文化中心的话，你亦应已亲身感受到超过 100 人一起跳 ParaPara 的感动场面，可是到了後期文化中心全面禁止这种街头文化在文化中心发展而令到 ParaPara 在香港的发展受到少许阻滞，直到 2001 年年中，香港 ParaPara 舞蹈总会成立後在租用场地方面取得进展而可以继续推广 ParaPara 这种运动. 文化中的衣著 ParaPara Dancing 的衣著在日本亦是很讲究的呢! 有的男仕会穿上西装, 有的男仕会穿上夏威夷 shirt. 女的大部份都会穿上花花裙, 而且其中会化上"朱古力"妆, 这个妆的重点在於把身上像朱古力的肤色及涂上一层浅色的眼影. 其实 ParaPara Dancing 是一种自由度很大的舞蹈, 衣著方面最重要只是轻便, 不会妨碍到跳 ParaPara 便行 . 而且每一首 Eurobeat 的歌也可以自创 ParaPara Dancing, 但当然必需学懂基本的舞姿, 舞步及 ParaPara 的 concept. 大家不妨学学 ParaPara Dancing, 感受一下一大群 ParaPara Dancers 一起跳 , 一起唱的感动场面吧!跳出新景象在日本，六名舞蹈员以明星的姿态组成 ParaPara All Star ，虽然商业味道比较重，但是她们的出现对 ParaPara 持续发展始终功不可抹.

常春藤联盟由美国东北部之八所学校组合而成：布朗大学、哥伦比亚大学、康奈尔大学、达特茅斯学院、哈佛大学、宾夕法尼亚大学、普林斯顿大学、及耶鲁大学。除康奈尔大学外，所有这些学校均在北美独立战争前创设，每所院校的入学标准均非常严格。这些学校之间的学术与运动竞争性纪录始于十九世纪末。常春藤(Ivy League)一词是指美国东北部八所大学体育联盟，包括：哈佛(Harvard)成立于1636年，耶鲁(Yale)成立于1701年，宾夕法尼亚大学(Penn)成立于1740年，普林斯顿(Princeton)成立于1746年，哥伦比亚(Columbia)成立于1754年，布朗(Brown)成立于1764年，达特茅斯(Dartmouth)成立于1769年，康奈尔(Cornell)成立于1865年。名称的由来：根据一种理论，“常春藤联盟”之原名应追溯到1937年，一位《纽约报》(New York Herald Tribune)体育新闻记者斯坦利·伍德沃德（Stanley Woodward）先生铸造了此名词，因美国最古老及最精英的学校建筑物均被常春藤覆盖住。另外一个理论对此名词的解释则较为古老，来自较早称之为“四联盟”（Four League）的运动协会，成员包括哥伦比亚大学、哈佛大学、普林斯顿大学和耶鲁大学。以上内容参考：百度百科-长春藤盟校

(2).XD作为网络用语，也可以解释为：兄弟。例如：XD们，给介绍几款好玩的游戏。Orz(OT2)Orz，又称作失意体前屈，是一种源自于日本的网路象形文字(或心情图示)，并且在2004年时在日本、台湾、大陆与香港俨然已经成为一种新兴的网路文化。失意体前屈，原本指的是网路上流行的表情符号：＿|￣|○。看起来像是一个人跪倒在地上，低着头，一副“天啊，你为何这样对我”的动作，虽然简单却很传神。在初期的时候，并没有人对这个符号起个名字，“失意体前屈”也是后来才出现的，据说是某个餐厅的座垫上绣着这五个字，至于再之前又是谁想到的，就不可考了。后来，又有人发现，用简单的三个英文字也可以表现这个动作，于是Orz就开始流行了。后来，更有Orz的日志软体、日志网站！这种文字可以写作Orz、oro、Or2、On_、Otz、OTL、sto、Jto、○|￣|_等，但其中以“Orz”最为常用；并有混合型，表示无可奈何的“囧rz”。原始用意带有“悔恨”、“悲愤”、“无力回天”等的含意，最明显的用法就是在于被甩(失恋)的时候。

乳胶枕头是近年来市面上很火爆的一种枕头，乳胶枕头不仅可以让我们的睡眠更加好，而且可以保护我们的脊椎。如果我们脊椎产生问题，可能会对生活习惯产生影响，并且造成四肢麻木，不利于我们的健康。选择一款适合自己的乳胶枕头是很多人关心的问题，那么，应该如何选择乳胶枕头呢?一、保养方法枕头作为人们生活中不可缺少的家庭日用品，和被褥等组成了家族众多的床上用品系列。同为床上用品，人们通常却只注意清洁凉晒被褥、枕巾、枕套，却很少把枕头请到屋外透气、晾晒。殊不知，每晚睡觉时，枕头是被褥里污浊气息通过的咽喉要道，加之人睡觉时，呼出的不纯净气体大量地渗入，以及头皮分泌的汗渍、污垢，使枕头成为脏乱差的藏污纳垢场所。仅靠清洗外部的枕巾和枕套，只是治标不治本，枕芯内的污秽气息却不能除掉，所以枕头已经成为现代家庭中最不干净的地方之一，称之为枕头的卫生盲区，特意制作的枕头晒袋专门用于家庭方便晾晒自己的枕头。尤其应当注意的是，倘若是呼吸道、消化道或头部皮肤有传染病者，还会将细菌和病毒染于枕芯内，有可能导致夫妻或孩子之间的交叉感染。所以建议您，您的枕头要经常晾晒消毒，保持卫生，有条件的家庭，除多晒枕头外，还应经常更换枕芯，按照医学专家的建议枕芯至少每两年换一次，最好每周都晒一次。二、选择方法枕头内材结构软硬、造型规格是影响孩子驼背的重要原因。枕头的作用是用来承托颈椎的，太高、太大、太硬都会影响胸椎(即肩椎)的向前倾斜，久而久之使孩子幼嫩的颈椎产生了变形，严重的会导致孩子驼背。建议1岁以前的孩子宜用专用的婴儿童枕头，1-5岁可用小号枕头，厚度2-5CM。材料要较软及透气。6-10岁可以用中号枕头，厚度5-8CM，材料要软、透气且韧性好。12-18岁可以用中大号枕头，厚度8-12CM,材料为微软、透气好、韧性好。三、选购使用1、是否100%天然乳胶合成乳胶来源于石油，天然乳胶来源于橡胶树。有淡淡的橡胶味，更加亲近自然，成本更高。2、生产工艺国内多数乳胶产品都是邓禄普生产工艺，特拉蕾工艺的产品质量更好，但由于成本问题，价格高些。3、寝具的密度枕头最佳密度在40-45间，太大太小都不好。床垫的最佳密度在80左右。4、市场上关于乳胶枕的叫法有些混乱，一些人工合成的泡沫、海绵枕也被称之为乳胶枕，乳胶枕也有合成乳及天然乳胶的之分，购买时应询问清楚。5、唯有真正的乳胶枕，才会散天然的乳香味。而其他材质是没有的。6、真正的乳胶枕是有几千个蜂巢式气孔，比其它纤维容纳更多的空气。7、手感，用手触摸，舒适感觉犹如皮肤。

数学解题与数学发现一样，通常都是在通过类比、归纳等探测性方法进行探测的基础上，获得对有关问题的结论或解决方法的猜想，然后再设法证明或否定猜想，进而达到解决问题的目的．类比、归纳是获得猜想的两个重要的方法．运用类比法解决问题，其基本过程可用框图表示如下：可见，运用类比法的关键是寻找一个合适的类比对象．按寻找类比对象的角度不同，类比法常分为以下三个类型． 将三维空间的对象降到二维（或一维）空间中的对象，此种类比方法即为降维类比．【例2】以棱长为1的正四面体的各棱为直径作球，S是所作六个球的交集．证明S中没有一对点的距离大于1。【分析】考虑平面上的类比命题：“边长为1的正三角形，以各边为直径作圆，S‘是所作三个圆的交集”，通过探索S"的类似性质，以寻求本题的论证思路．如图，易知S‘包含于以正三角形重心为圆心，以为半径的圆内．因此S"内任意两点的距离不大于1以此方法即可获得解本题的思路。证明：如图，正四面体 ABCD中，M、N分别为BC、AD的中点，G为△BCD的中心，MN∩AG=O．显然O是正四面体ABCD的中心．易知OG=·AG=，并且可以推得以O为球心、OG为半径的球内任意两点间的距离不大于，其球O必包含S．现证明如下。根据对称性，不妨考察空间区域四面体OMCG．设P为四面体OMCG内任一点，且P不在球O内，现证P亦不在S内。若球O交OC于T点。△TON中，ON=，OT=，cos∠TON=cos（π-∠TOM)=-。由余弦定理：TN2=ON2+OT2+2ON·OT·=，∴TN=。又在 Rt△AGD中，N是AD的中点，∴GN=。由GN= NT=， OG=OT， ON=ON，得 △GON≌△TON。∴∠TON=∠GON，且均为钝角．于是显然在△GOC内，不属于球O的任何点P，均有∠PON>；∠TON，即有PN>TN=，P点在 N为球心，AD为直径的球外，P点不属于区域S．由此可见，球O包含六个球的交集S，即S中不存在两点，使其距离大于． 某些待解决的问题没有现成的类比物，但可通过观察，凭借结构上的相似性等寻找类比问题，然后可通过适当的代换，将原问题转化为类比问题来解决．【例3】任给7个实数xk（k=1，2，…，7)．证明其中有两个数xi，xj，满足不等式0≤≤·【分析】若任给7个实数中有某两个相等，结论显然成立．若7个实数互不相等，则难以下手．但仔细观察可发现：与两角差的正切公式在结构上极为相似，故可选后者为类比物，并通过适当的代换将其转化为类比问题．作代换：xk=tanαk（k =l，2，…，7），证明必存在αi，αj，满足不等式0≤tan（αi-αj）≤·证明：令xk=tanαk（k =l，2，…，7），αk∈（-，），则原命题转化为：证明存在两个实数αi，αj∈（-，），满足0≤tan（αi-αj）≤·由抽屉原则知，αk中必有 4个在[0，）中或在（-，0）中，不妨设有4个在[0，）中．注意到tan0=0，tan=，而在[0，）内，tanx是增函数，故只需证明存在αi，αj，使0<；αi-αj <即可。为此将[0，）分成三个小区间：[0，]、（，]、（，）。又由抽屉原则知，4个αk中至少有2个比如αi，αj同属于某一区间，不妨设αi>；αj，则0≤αi-αj ≤，故0≤tan（αi-αj）≤·这样，与相应的xi=tanαi、xj=tanαj，便有0≤≤· 简化类比，就是将原命题类比到比原命题简单的类比命题，通过类比命题解决思路和方法的启发，寻求原命题的解决思路与方法．比如可先将多元问题类比为少元问题，高次问题类比到低次问题，普遍问题类比为特殊问题等．【例4】已知xi≥0（i=1，2，…，n），且xl+x2+…+xn=1。求证：1≤++…+≤．【分析】我们可先把它类比为一简单的类比题：“已知xl≥0，x2≥0，且xl+x2 =1，求证1≤+≤”．本类比题的证明思路为：∵2≤xl+x2=l，∴0≤2≤1，则1≤xl+x2+2≤2，即1≤（+)2≤2，∴1≤+≤．这一证明过程中用到了基本不等式和配方法．这正是要寻找的证明原命题的思路和方法．证明：由基本不等式有0≤2≤xi+xj，则0≤2≤（n-1)(xl+x2+…+xn)=n-1∴1≤xl+x2+…+xn +2≤n，即1≤（++…+)2≤n∴1≤++…+≤．所谓归纳，是指通过对特例的分析来引出普遍结论的一种推理形式．它由推理的前提和结论两部分构成：前提是若干已知的个别事实，是个别或特殊的判断、陈述，结论是从前提中通过推理而获得的猜想，是普遍性的陈述、判断．其思维模式是：设Mi（i=1，2，…，n）是要研究对象M的特例或子集，若Mi（i=1，2，…，n）具有性质P，则由此猜想M也可能具有性质P．如果=M，这时的归纳法称为完全归纳法．由于它穷尽了被研究对象的一切特例，因而结论是正确可靠的．完全归纳法可以作为论证的方法，它又称为枚举归纳法．如果是M的真子集，这时的归纳法称为不完全归纳法．由于不完全归纳法没有穷尽全部被研究的对象，得出的结论只能算猜想，结论的正确与否有待进一步证明或举反例．本节主要介绍如何运用不完全归纳法获得猜想，对于完全归纳法，将在以后结合有关内容（如分类法）进行讲解．【例5】证明：任何面积等于1的凸四边形的周长及两条对角线的长度之和不小于4十．【分析】四边形的周长和对角线的长度和混在一起令人棘手，我们可以从特例考察起：先考虑面积为1的正方形，其周长恰为4，对角钱之和为2即．其次考察面积为1的菱形，若两对角线长记为l1、l2，那么菱形面积S=l1·l2，知l1+ l2≥2=2=，菱形周长：l=4≥2=4。由此，可以猜想：对一般的凸四边形也可将其周长和对角线长度和分开考虑．【证明】设ABCD为任意一个面积为1的凸四边形，其有关线段及角标如图．则SABCD= (eg+gf+fh+he)sinα≤ (e+f)(g+h）≤，∴e+f+g+h≥2，即对角线长度之和不小于．∴a+b+c+d≥4，即周长不小于4．综上所述，结论得证，
