speak
speak讲语言 speak to sb about sth
tell告诉 tell sb sth/tell sth to sb
say说 say sth to sb
talk交谈,聊天 talk to sb/talk sb about sth
say ,speak talk 和tell辨析.

词或宾语从句.
eg:He can say his name.他会说他的名字.
Please say it in English.请用英语用.
She`s saying ,Don`t draw on the wall.她在说“别在墙上画”.
▲ speak强调说的动作,不强调所说的内容 .作及物动词时,常以某种
语言作宾语.作不及物动词时,常见的搭配形式有：

证明：∵平行四边形ABCD的对角线相交于点O
∴OA=OC,AD∥BC
∴∠OAE＝∠OCF,∠OEA＝∠OFC
∴△OAE≌△OCF(AAS)
∴AE=CF,OE=OF
解⑴由上BC=BF+FC=BF+AE=4+2,.8=6.8
⑵梯形AEFB的周长=AE+EF+BF+AB==AE+2OE+BF+AB=2.8+2+4+3.8=12.6

火山爆发后由于温度下降,凝固成固体的岩石.
其物态的变化是：靠近火山口的由液体变成固体,远离火山口的细小东西由液态变成火山灰和气体.
当然,在火山喷发的过程中还会形成许多新的矿物和岩石.
产生这些变化的原因主要是由于压力和温度产生变化,在高温和高压的地质环境中,是处于液态的形态存在,一旦在自然环境中,这些岩浆就会由于压力的改变和温度的下降而固结和气化.

物体运动速度快慢和 物体质量的大小 与 作用于物体的力的大小 和 物体所受的阻力有关!物体质量越小,作用于物体的力越大,物体所受阻力越小,速度就越快!
子弹速度之所以比火车快,可以从以上三个条件分析!
火车的质量远比子弹大!
火车所受的阻力远比子弹大!
火车所受的力远比子弹大!
虽然火车所受的作用力远比子弹大,但是子弹的质量远比火车小和所受阻力远比火车小!综合以上的描述,子弹的速度比火车快!

宽容
词 目 宽容
读 音 kuān róng
解 释 原谅,饶恕,不予以计较追究
宽容别人,其实就是宽容我们自己.多一点对别人的宽容,其实,我们生命中就多了一点空间.有朋友的人生路上,才会有关爱和扶持,才不会有寂寞和孤独；有朋友的生活,才会少一点风雨,多一点温暖和阳光.其实,宽容永远都是一片晴天.
2.宽容就是忘却.人人都有痛苦,都有伤疤,动辄去揭,便添新创,旧痕新伤难愈合.忘记昨日的是非,忘记别人先前对自己的指责和谩骂,时间是良好的止痛剂.学会忘却,生活才有阳光,才有欢乐.
3.宽容就是不计较,事情过了就算了.每个人都有错误,如果执著于其过去的错误,就会形成思想包袱,不信任、耿耿于怀、放不开,限制了自己的思维,也限制了对方的发展.即使是背叛,也并非不可容忍.能够承受背叛的人才是最坚强的人,也将以他坚强的心志在氛围中占据主动,以其威严更能够给人以信心、动力,因而更能够防止或减少背叛.
4.宽容就是潇洒.“处处绿杨堪系马,家家有路到长安.”宽厚待人,容纳非议,乃事业成功、家庭幸福美满之道.事事斤斤计较、患得患失,活得也累,难得人世走一遭,潇洒最重要.
5.宽容是一种坚强,而不是软弱.宽容要以退为进、积极地防御.宽容所体现出来的退让是有目的有计划的,主动权掌握在自己的手中.无奈和迫不得已不能算宽容.宽容的最高境界是对众生的怜悯.
6.宽容就是在别人和自己意见不一致时也不要勉强.从心理学角度,任何的想法都有其来由.任何的动机都有一定的诱因.了解对方想法的根源,找到他们意见提出的基础,就能够设身处地,提出的方案也更能够契合对方的心理而得到接受.消除阻碍和对抗是提高效率的唯一方法.任何人都有自己对人生的看法和体会,我们要尊重他们的知识和体验,积极吸取之间的精华,做好扬弃.
7.宽容就是忍耐.同伴的批评、朋友的误解,过多的争辩和“反击”实不足取,惟有冷静、忍耐、谅解最重要.相信这句名言：“宽容是在荆棘丛中长出来的谷粒.”能退一步,天地自然宽.
8.宽容也需要技巧.给一次机会并不是纵容,不是免除对方应该承担的责任.任何人都需要为自己的行为负责；任何人都要承担各种各样的后果.否则,对方会一而再、再而三地犯禁（错）,显示出软弱.
9.格言：
紫罗兰把它的香气留在那踩扁了它的脚踝上.这就是宽怒.” ——马克吐温
君子之道,忠恕而已矣.己所不欲,勿施于人.我不欲人之加诸我也,吾亦欲无加诸人.（论语）
泰山不让土壤,故能成其大；河海不择细流,故能成其深.（李斯）
“宽容就像天上的细雨滋润着大地.它赐福于宽容的人,也赐福于被宽容的人.——莎士比亚名剧《威尼斯商人》中一段台词
宽容是文明的唯一考核（海尔普斯）
智慧的艺术就是懂得该宽容什么的艺术（威廉·詹姆斯）
宽宏精神是一切事物中最伟大的（欧文）
生活中有许多这样的场合：你打算用忿恨去实现的目标,完全可能由宽恕去实现的目标,完全可能由宽恕去实现（西德尼·史密斯）
诚挚地宽恕,再把它忘记（英国）
宽宥是人性的,而忘却是神性的（詹姆斯·格兰）
宽容的人最为性急,耐受力强的人最不宽容（贝尔奈）
最高贵的复仇是宽容（雨果）
生活过,而不会宽容别人的人,是不配受到别人的宽容的.但是谁能说是不需要宽容的呢?（屠格涅夫）
正义之神,宽容是我们最完美的所作所为（华兹华斯）
只有勇敢的人才懂得如何宽容；懦夫决不会宽容,这不是他的本性（斯特恩）
宽容要么对人有益,要么对人有害（伯克）
损着别人的牙眼,却反对报复,主张宽容的人,万勿和他接近----（鲁迅）

This book provides pretty much everything we've been promised from the outset: an ending, and a satisfying one at that -- but not without its price. Many die, not just the two Rowling mentioned in so many interviews. Many beloved characters die, and some of them die "off screen" as it were, so that we as readers aren't even privy to the details of their deaths, or their final moments of life. Some of these deaths will bring tears to the eyes of any loyal Potter devotee, I've no doubt of that. But as for the main death, the one so many have wondered about? Well, that's where Rowling falls back on a few too-worn literary devices, and where she loses one of her stars.
I found this book to be far too full of easy short cuts and simplistic cliches to give it five stars. Far too many times, Harry and his friends were "mysteriously" saved at the last minute. And the real answers to these so-called mysteries will fall much more easily into the hands of die-hard Potter fanatics who've spent hours studying the books and pouring over the fan sites than they ever do into the hands of the characters themselves. This is too often frustrating. Perhaps it's unfair to criticize or punish Rowling for the perseverance and intelligence of her fans, but the fact is that many of her secrets have been guessed. In fact, the few that haven't seem only to surprise because Rowling conveniently has them pop up for the first time in this book. Magical objects we've seen many times before suddenly have new and useful -- and VERY convenient -- magical properties. People we've only heard of have convenient new information and relevance to the plot.
She lost the other star because of omissions. Unexplained (and again, very convenient) plot twists, otherwise known as plot holes, are all over the book. A book this long that purports to be the end of an epic series should not have this many plot holes and inexplicable events. (None of which I can go into detail about without giving up major spoilers -- sorry.) And most damning of all, when some of the plot holes are explained, it's done in a manner resembling what the brilliant movie "The Incredibles" referred to as "monologuing" -- when one character (usually the bad guy) sits around explaining the whole plot and nothing bad happens to the good guys while all these lose ends are conveniently tied up. For some reason, the villain, no matter how vicious he has been throughout the story, always conveniently waits to attack until the hero's had plenty of time to get all the answers he needs to defeat the bad guy. The only change Rowling makes to this shopworn device is that she does it via magical means. (Though in her case, the magical mean in question is the Pensieve -- something shopworn in and of itself, considering the number of times it's now been used in this series to convey crucial information.) I was also sorely disappointed to realize that she left out a number of things she practically promised fans would be included in this book. For instance, many fans have asked her what Harry's parents did for a living. She always said she couldn't tell us because it would be too big a plot spoiler for the upcoming novels. Well, now the novels are all finished and we still don't know. Why didn't she include that in this final book, if it really was supposed to matter so much? And why did she leave so much crucial information out of her far too short epilogue?
There is no doubt that in Harry Potter Rowling has created a brave and endurable hero, one who will linger in the hearts and minds of readers for generations to come. But in this humble reader's opinion, she has also created one for whom the struggle ended a bit too quickly and easily, of whom too many things are left unknown, and for whom answers and help came too readily and too conveniently in the end.
Then again . . . maybe I just wanted it to last a little longer. Because it's over now, and nothing like Harry Potter is ever happening to this humble reader again.

（√3 - 3√12 - √6）× 2√3 + 5√2直接乘开
就是（√3*2√3）-（3√12 *2√3 ）-（√6*2√3）+5√2
=6-36-6√2+5√2
=-30-√2
