1.(4x）^(4x)的3次方+(-4x)^(-4x)的3次方
=（4x^(4x)^3+((-4x)^(-4x))^3
=(4x)^(12x^3)+((-4x)^(-12x^3)) 不好意思 这道题不大会
2.（-2x^)的3次方+(-3x的3次方)^+(-x)的6次方 =-8x^3-27x^3+x^6=-35x^3+x^6
3.（x-2)(x+1)-2(x-3)(x+2) =x^2+x-2x-2-2(x^2-x-6)=x^ 2-x-2-2x^2+2x+12=-x^2+x+10
4.(x-5y)(x-y)-6(x+2y)(x-3y)=x^2-xy-5xy+5y^2-6(x^2-3yx+2yx-6y^2)

平移对角线加勾股定理,过程如下：
证明：过点D作DE‖AC交BC的延长线于点E
∵AC⊥BD,∴DE⊥BD
∵Rt△BDE中,有BD^2+DE^2=BE^2
又∵BD=BO+OD,DE=AC=OA+OC,BE=BC+CE=BC+AD
∴(OB+OD）^2+（OA+OC）^2=（AC+BD）^2
即OB^2+ +2OB•OD+OD^2+ OA^2+2OA•OC+ OC^2= AD^2 +2AD•BD+BD^2
∵ 在Rt△AOD中,有OA^2+OD^2=AD^2
在Rt△BOC中,有OB^2+OC^2=BD^2
∴2OB•OD+2OA•OC=2AD•BD
∴OB•OD+ OA•OC= AD•BD

many changes are taking place in " food styles" in the United States.The United States is traditionalyy famous for its very solid and unchanging diet,which is chiefly made up of mmeat and potatoes.Now we have many different alternative to choose from:various ethnic food,health food,and fast food,in addition to the traditional home-cooked meal.
Ethnic restaurants and supermatkets are common in the United States.Because the U.S is a country of immigrant,there is an immense variety of ethnic food.Most American cities and towns are fiiled with restaurants serving international cooking.Many even have ethnic sections:Chinatown,Little Italy,or Germantown.With this vast ethnic choice,we can enjoy food from all over the world.Besides sections of cities,there ethnic regions,which are well known for certain food because of the people who settled there.For example.in southern California,there many Mexican restaurants.
Health food gained popularty when people began to think more seriously about their phsical well-being.The very term health food is ironic beacuse it impies that there is also "unhealthy" food.Healh food is fresh,natural.unprocessed,which does not contain preservatives to make it last longer or chemicals to make it taste or look better.Pople who are keen on health food are uauslly vegetaries,who prefer to get their essential proteins from sources other than meat,such as beans,chees,and eggs.
Fast food restaurants are now expanding rapidly all over the country.In the United States,speed is a very important factor.People uauslly have a short lunch break or they just do not want to waste their time eating.fast food restaurants are places that take care of hundreds of people in a short time.There is uauslly very little waiting,and the food is always cheap.Some examples are burger and Pizza places.
America"s attitude toward food is changing,too.Though the tradional big breakfast is losing popularty,people are rediscovering the social importance of food.Dinner with family or friends is again becoming a very special way of enjoying and sharing.Like so many Americans are taking time to relax and enjoy the finer taste at dinner,evevn if they still rush through lunch at a hamburger stand.终于打完啦!

鲁迅嚼辣椒驱寒
央视国际 2003年07月21日 17:21
鲁迅先生从小认真学习.少年时,在江南水师学堂读书,第一学期成绩优异,学校奖给他一枚金质奖章.他立即拿到南京鼓楼街头卖掉,然后买了几本书,又买了一串红辣椒.每当晚上寒冷时,夜读难耐,他便摘下一颗辣椒,放在嘴里嚼着,直辣得额头冒汗.他就用这种办法驱寒坚持读书.由于苦读书,后来终于成为我国著名的文学家.

君子曰：学不可以已。青，取之于蓝，而青于蓝；冰，水为之，而寒于水。木 直中绳，揉以为轮，其曲中规，虽有槁暴，不复挺者，〔车柔〕使之然也。故木受 绳则直，金就砾则利。君子博学而日参省乎己，则知明而行无过矣。
故不登高山，不知天之高也；不临深〔奚谷〕，不知地之厚也；不闻先王之遗 言，不知学问之大也。于越夷貉之子，生而同声，长而异俗，教使之然也。诗曰： “嗟尔君子，无恒安息。靖恭尔位，好是正直。神之听之，介尔景福。”神莫大于 化道，福莫长于无祸。
吾尝终日而思矣，不如须臾之所学也。吾尝〔足支〕而望矣，不如登高之博见 也。登高而招，臂非加长也，而见者远。顺风而呼，声非加疾也，而闻者彰。假舆 马者，非利足也，而致千里。假舟辑者，非能水也，而绝江河。君子生非异也，善 假于物也。
南方有鸟焉，名曰“蒙鸠”，以羽为巢，而编之以发，系之苇苕。风至苕折， 卵破子死。巢非不完也，所系者然也。西方有木焉，名曰“射干”，茎长四寸，生 于高山之上，而临百仞之渊。木茎非能长也，所立者然也。蓬生麻中，不扶而直。 〖白沙在涅，与之俱黑。〗兰槐之根是为芷，其渐之□（异体“修”加三点水）， 君子不近，庶人不服。其质非不美也，所渐者然也。故君子居必择乡，游必就士， 所以防邪僻而近中正也。
物类之起，必有所始。荣辱之来，必象其德。肉腐出虫，鱼枯生蠹。怠慢忘身 ，祸灾乃作。强自取柱，柔自取束。邪秽在身，怨之所构。施薪若一，火就燥也。 平地若一，水就湿也。草木畴生，禽兽群焉，物各从其类也。是故质的张而弓矢至 焉，林木茂而斧斤至焉，树成荫而众鸟息焉，醯酸而蚋聚焉。故言有召祸也，行有 招辱也，君子慎其所立乎！
积土成山，风雨兴焉。积水成渊，蛟龙生焉。积善成德，而神明自得，圣心备 焉。故不积跬步，无以至千里；不积小流，无以成江海。骐骥一跃，不能十步；驽 马十驾，功在不舍。锲而舍之，朽木不折；锲而不舍，金石可镂。蚓无爪牙之利， 筋骨之强，上食埃土，下饮黄泉，用心一也。蟹六跪而二螯，非蛇□（“擅”换虫 旁）之穴无可寄托者，用心躁也。是故无冥冥之志者，无昭昭之明。无〔忄昏〕〔 忄昏〕之事者，无赫赫之功。行衢道者不至，事两君者不容。目不能两视而明，耳 不能两听而聪。□（“腾”中“马”换“虫”）蛇无足而飞，梧鼠五枝而穷。诗曰 ：“尸鸠在桑，其子七兮。淑人君子，其仪一兮。其仪一兮，心如结兮。”故君子 结于一也。
昔者瓠巴鼓瑟而流【沉】鱼出听，伯牙鼓琴而六马仰秣。故声无小而不闻，行 无隐而不形。玉在山而草木润，渊生珠而崖不枯。为善不积邪？安有不闻者乎！ 学恶乎始？恶乎终？曰：其数则始乎诵经，终乎读礼。其义则始乎为士，终乎 为圣人。真积力久则入，学至乎没而后止也。故学数有终，若其义则不可须臾舍也 。为之，人也；舍之，禽兽也。故书者，政事之纪也。诗者，中声之所止也。礼者 ，法之大分，群类之纲纪也。故学至乎礼而止矣。夫是之谓道德之极。礼之敬文也 ，乐之中和也，诗书之博也，春秋之微也，在天地之间者毕矣。
君子之学也，入乎耳，箸乎心，布乎四体，形乎动静。端而言，蠕而动，一可 以为法则。小人之学也，入乎耳，出乎口，口耳之间则四寸耳，曷足以美七尺之躯 哉！古之学者为己，今之学者为人。君子之学也，以美其身。小人之学也，以为禽 犊。故不问而告谓之傲，问一而告二谓之〔口赞〕。傲，非也；〔口赞〕，非也； 君子如向矣。
学莫便乎近其人。礼乐法而不说，诗书故而不切，春秋简而不速。方其人之习 君子之说，则尊以遍矣，周于世矣。故曰：学莫便乎近其人。
学之经莫速乎好其人，隆礼次之。上不能好其人，下不能隆礼，安特将学杂识 志顺诗书而已耳！则末世穷年，不免为陋儒而已。将原先王，本仁义，则礼正其经 纬蹊径也。若挈裘领，诎五指而顿之，顺者不可胜数也。不道礼宪，以诗书为之， 譬之犹以指测河也，以戈舂黍也，以锥飧壶也，不可以得之矣。故隆礼，虽未明， 法士也；不隆礼，虽察辩，散儒也。
问苦者，勿告也。告苦者，勿问也。说苦者，勿听也。有争气者，勿与辩也。 故必由其道至，然后接之，非其道则避之。故礼恭，而后可与言道之方；辞顺，而 后可与言道之理；色从，而后可与言道之致。故未可与言而言谓之傲，可与言而不 言谓之隐，不观气色而言谓之瞽。故君子不傲不隐不瞽，谨顺其身。诗曰：“匪交 匪舒，天子所予。”此之谓也。
百发失一，不足谓善射。千里跬步不至，不足谓善御。伦类不通，仁义不一， 不足谓善学。学也者，固学一之也。一出焉，一入焉，涂巷之人也。其善者少，不 善者多，桀纣盗跖也。全之尽之，然后学者也。
君子知夫不全不粹之不足以为美也，故诵数以贯之，思索以通之，为其人以处 之，除其害者以持养之。使目非是无欲见也，使耳非是无欲闻也，使口非是无欲言 也，使心非是无欲虑也。及至其致好之也，目好之五色，耳好之五声，口好之五味 ，心利之有天下。是故权利不能倾也，群众不能移也，天下不能荡也。生乎由是， 死乎由是，夫是之谓德操。德操然后能定。能定然后能应。能定能应，夫是谓之成 人。天见其明，地见其光，君子贵其全也。
选用的段落
君子曰：学不可以已。青，取之于蓝，而青于蓝；冰，水为之，而寒于水。木 直中绳，揉以为轮，其曲中规，虽有槁暴，不复挺者，〔车柔〕使之然也。故木受 绳则直，金就砾则利。君子博学而日参省乎己，则知明而行无过矣。
