58岁时横渡英吉利海峡
一年多前，我开始为今年九月横渡英吉利海峡进行训练。届时我将年满58岁。
朋友们以为我疯了；我妻子倒没觉得我疯了，就是有点担心。人们一再问我的问题是：为什么？
最近，印第安纳州的一位见习记者问了我这个问题，我说：“让我先问你一个问题。今年夏天你有些什么打算？”他回答说打算去超市打工。我无需再说什么，他已经明白了我的意思。
不管你是20岁还是58岁，都喜欢接受挑战，干些带有冒险意味的事儿；而为横渡英吉利海峡做准备，远比在超市打工有意义，尤其是当你有所选择的时候。
可我究竟为什么决定要在58岁时横渡英吉利海峡呢？也许我自己也很难做出满意的回答。
对游泳爱好者来说，英吉利海峡向来是莫大的挑战: 它是对能力、耐力、运气，以至勇敢精神的一种考验。正是这一挑战，每年吸引了大约100名左右的游泳爱好者，他们心甘情愿地投入时间、经历和财力，一试身手。
有一点更增添了我的兴趣，那就是，我要是成功了，将成为迄今为止年龄最大的英吉利海峡畅游者。
我不认为自己是个超人，但我确实觉得自己至少有两个有利条件：
首先，我正在刻苦训练——现在每天游7.5 英里。在此之前，我一直坚持适度的刻苦训练，以保持良好的身体状态。
其次，我是个不屈不挠的人。我一旦确立了目标，便不会轻易放弃。横渡英吉利海峡早就是我的一个目标。我有一种预感，觉得自己会做好充分思想准备的，绝不会像几年前某位英吉利海峡的横渡者那样半途而废。他刻苦训练了两三年，做好了种种安排，甚至在赛前几星期就去英国，在英格兰海峡进行实地训练。重要的日子到来了，他开始向法国游去；才游了一个小时，他就从水里出来，爬上小船，说自己突然失去了横渡英吉利海峡的意愿，这事对他不再有什么意义了。
相反，有位姑娘在海面涌起激浪时，力图游完全程。由于海浪汹涌，海水冰凉，她游得很辛苦，这时她的教练在船上向她叫喊，认为她应该知难而退，弃水上船。她大声回应说：“是我在游，我会决定该什么时候上来的。”结果她成功了。
搭车者
昨天深夜，约翰·亨德森驱车回家，他刚出了一趟令人筋疲力尽的公差。为了在半夜之前赶到家，他把参观公司新总部的事儿也往后推迟了，而此刻他却难以保持清醒。他打开收音机，想把注意力集中的新闻上----是关于一则抢劫什么的----可他的眼皮老是不由自主地要合上。他妻子待在代顿的家里，长途旅行时，他真希望有他在自己身旁作伴。
就在这时他注意到路旁有个人想搭车。他不假思索地减慢车速，让车停下来。那个年轻人在雨中已淋得浑身湿透。看上去怪可怜的，约翰不禁为他感到难过。“上车吧，”他说。
约翰想起了自己从前没车时不得不从学校搭便车回家的情景。一连几个小时坐在路旁等别人让他搭车，他实在忍受不了。
搭车者一上了车，约翰顿生后悔之意。年轻人有张奇特的脸，两道目光锐利逼人。他的衣服又脏又旧，长长的头发也该剪剪了。搭车者点着一支烟，说他要去伍兹威尔。但当约翰问到别的问题时，年轻人却避而不谈任何有关他人个的情况，并改变了话题。
约翰身上开始冒冷汗，他情绪紧张，禁不住想到自己的钱包，想到了带在身边的所有钱财。他竭力想回忆刚才播音员说的那起抢劫案。别犯傻了，他对自己说。别胡思乱想！这家伙不是罪犯。再说惊慌又管什么用？
约翰三个月前就戒了烟，可这会儿他忍不住想抽一支。他向他的乘客要了一支烟，但他
却不得不等自己的双手停止颤抖后才点上烟。到了下一个小镇，约翰把车停下，说: “我实在是睁不开眼了，看来我得想办法找家旅馆，在这儿过夜了.” 他神情紧张地向搭车者道谦，说不能送他去伍兹威尔了。
年轻人慢慢把手伸向口袋. “这一下要亮招了,”约翰在想, “我在劫难逃”。就在那一刻，他考虑大声呼救，但搭车人掏出来的既不是枪也不刀子，而是几张皱巴巴的钞票，并要把这些钱给约翰. “哦，不，我不要钱。你只管下车得了，行吗?”
年轻人显得有点困惑，执意要塞钱给约翰---500美金. “你瞧，我父亲是石油大王约翰·贝尔斯福特,” 他说, “谢谢你送了我这么远的一段路程.”
直到搭车者从视野中消失，约翰才猛踩油门，开车向镇外疾驰而去。他急着想赶回家。玛莎说什么也不会相信有这种事的！他暗自这么思忖。
数学专业英语课后答案
2.1 数学、方程与比例 （1）数学来源于人类的社会实践，包括工农业的劳动，商业、军事和科学技术研究等活动。 Mathematics comes from man’s social practice, for example, industrial and agricultural production, commercial activities, military operations and scientific and technological researches. （2）如果没有运用数学，任何一个科学技术分支都不可能正常地发展。 No modern scientific and technological branches could be regularly developed without the application of mathematics. （3）符号在数学中起着非常重要的作用，它常用于表示概念和命题。Notations are a special and powerful tool of mathematics and are used to express conceptions and propositions very often. （4）17 世纪之前，人们局限于初等数学，即几何、三角和代数，那时只考虑常数。 Before 17th century, man confined himself to the elementary mathematics, i. e. , geometry, trigonometry and algebra, in which only the constants were considered. （5）方程与算数的等式不同在于它含有可以参加运算的未知量。 Equation is different from arithmetic identity in that it contains unknown quantity which can join operations. （6）方程又称为条件等式，因为其中的未知量通常只允许取某些特定的值。Equipment is called an equation of condition in that it is true only for certain values of unknown quantities in it. （7）方程很有用，可以用它来解决许多实际应用问题。 Equations are of very great use. We can use equations in many mathematical problems. （8）解方程时要进行一系列移项和同解变形，最后求出它的根，即未知量的值。To solve the equation means to move and change the terms about without making the equation untrue, until the root of the equation is obtained, which is the value of unknown term. 2.2 几何与三角 （1）许多专家都认为数学是学习其他科学技术的必备基础和先决条件。 Many experts recognize that mathematics is the necessary foundation and prerequisite of studying other science technology. （2）西方国家的专家认为几何起源于巴比伦和埃及人的土地测量技术，其实中国古代的数学家对几何做了许多出色的研究。 The western experts think that geometry had its origin in the measurements by the Babylonians and Egyptians of their lands. Infect, the ancient Chinese mathematicians made much remarkable study for geometry. （3）几何的学习使学生在思考问题时更周密和审慎，他们将不会盲目接受任何结论。 In studying geometry, the student is taught to think clearly and critically and he is led away from the practice of blind acceptance of any conclusions. （4）数学培养学生的分析问题的能力，使他们能应用毅力、创造性和逻辑推理来解决问题。
各阶段英语创意作业的设计
关于小学到高中各阶段英语创意作业的设计建议 一、初学英语者，作业设计应以口头作业为主（适用于起始年级的第一学期） 小学生刚接触英语时，兴趣较高，但课后对知识的回生现象严重。设计作业时，应以口头作业为主，通过说说、唱唱、玩玩的方式，协助学生巩固课堂所学知识。 1.游戏。小学低年级学生年龄小，即使对简单的英语朗读活动，其兴趣也只能维持一小段时间。例如：在学习了表示五官的英语单词后，我让学生互玩游戏，彼此听对方发出的指令单词，来指自己的五官。这个活动旨在激发学生说英语的兴趣。 童谣，让学生以唱的方式完成英语作业。例如：在学生学习学习用具铅笔和钢笔等单词后，我把这些单词改编成学生熟悉曲调的儿歌，结合课本提供的童谣，让学生自己给加节奏。这是开发音乐智能一种尝试，让学生想想课堂的歌曲怎么唱，用的形式，节奏如何，与其它同学交流。(了解英语教学资讯，注重QQ824560647) 3.有表情的朗读趣味故事，将教材内容或资料中的材料经过精心的筛选后改编成朗朗上口的句子、顺口溜或小诗儿歌等利用早读和业余时间教会学生，学生读会后给同学、朋友、家长等朗读表演，培养语感水平。 二、中年级的作业应力求生活化（适用于四、五年级学生） 中年级学生虽然有一定学习英语的基础，但是同样应该注意趣味性。中年级学生有主动参与学习的意识。作业设计中更多体现口语化、生活化，让学生在完成作业的过程中学习，体验与巩固所学语言。 1.绘画 把绘画与语言相结合是开发空间智能和评阅智能的有效手段。在学习方位时，我让学生画一幅想像中的图并用英语叙述各种东西的位置；学习问路时，让学生编问路的对话并画出线路图。制作相对应的单词卡片、图画日记等。 2.手工制作 手工制作通常是英语课上运动智能的主要形式。为第二天的表演做头饰，人物形象由学生自己设计，能够是卡通式的、漫画式的，也能够是写式的；收集英文包装纸实行商标剪贴；收集生活中常用的英文标志。 三、高年级的作业应注意培养学生的思维水平（适合六年级学生）

英语作业及答案
下面的范文中有很多错误，请找出形容词与副词的混淆、冠词的遗漏和误用、介词和代词的误用等错误，并检查句子的完整性、单词拼写、主谓的一致性、动词和现在分词是否混淆、复数形式、动词的时态、词汇选择、词性、单词的顺序等问题。 (几乎每个句子都有错误) An university education is a goal of many high school students. Some students want to go into a profession that requires an university degree. But there are other professions that do not require a degree, but require certification from a technological college. The reasons why students make decisions to go to technical college instead of university probably have a lot to do with their choice of career, their own academic abilities and their financial situation. First of all, students make their choices for post-secondary education based on the fields that interest them. A student who is interested in medicine might decide to university, into a pre-med program to prepare to become a doctor, or they might go to nursing school or a nursing program in a technical college. Some career choices offer a choice of educational route. The university route is usually more intense and takes longer. For example, an interior designer might take a one or two year program at a college, or choose to do the degree program as a part of the architectural department at a university. Other career choices involve certification that is available at a college, like broadcast journal or

一起作业错题
五年级下册知识点归纳： 第二单元因数与倍数 1.整除：被除数、除数和商都是自然数，并且没有余数。 2.整数与自然数的关系：整数包括自然数。 3.因数、倍数：大数能被小数整除时，大数是小数的倍数，小数是大数的因数。 例：12是6的倍数，6是12的因数。 （1）数a能被b整除，那么a就是b的倍数，b就是a的因数。因数和倍数是相互依存的，不能单独存在。 （2）一个数的因数的个数是有限的，其中最小的因数是1，最大的因数是它本身。 一个数的因数的求法：成对地按顺序找。 （3）一个数的倍数的个数是无限的，最小的倍数是它本身。 一个数的倍数的求法：依次乘以自然数。 （4）2、3、5的倍数特征 1）个位上是0，2，4，6，8的数都是2的倍数。 2）一个数各个数位上的数的和是3的倍数，这个数就是3的倍数。 3）个位上是0或5的数，是5的倍数。 4）能同时被2、3、5整除（也就是2、3、5的倍数）的最大的两位数是90，最小的三位数是120。同时满足2、3、5的倍数，实际是求2×3×5=30的倍数。 5）如果一个数同时是2和5的倍数，那它的个位上的数字一定是0。 4、完全数：除了它本身以外所有的因数的和等于它本身的数叫做完全数。如：6的因数有：1、2、3（6除外），刚好1+2+3=6，所以6是完全数，小的完全数有6、28等 5：自然数按能不能被2整除来分：奇数、偶数。 奇数：不能被2整除的数。叫奇数。也就是个位上是1、3、5、7、9的数。 偶数：能被2整除的数叫偶数（0也是偶数），也就是个位上是0、2、4、6、8的数。 最小的奇数是1，最小的偶数是0. 关系：奇数+、- 偶数=奇数奇数+、- 奇数=偶数偶数+、-偶数=偶数。 6、自然数按因数的个数来分：质数、合数、1、0四类. 质数（或素数）：只有1和它本身两个因数。 合数：除了1和它本身还有别的因数（至少有三个因数：1、它本身、别的因数）。 1：只有1个因数。“1”既不是质数，也不是合数。 最小的质数是2，最小的合数是4，连续的两个质数是2、3。 每个合数都可以由几个质数相乘得到，质数相乘一定得合数。 20以内的质数：有8个（2、3、5、7、11、13、17、19） 100以内的质数有25个：2、3、5、7、11、13、17、19、23、29、31、37、41、43、47、53、59、61、67、71、73、79、83、89、97 100以内找质数、合数的技巧： 看是否是2、3、5、7、11、13…的倍数，是的就是合数，不是的就是质数。 关系：奇数×奇数=奇数质数×质数=合数 最大、最小 A的最小因数是：1；A的最大因数是：A；A的最小倍数是：A； 最小的自然数是：0；最小的奇数是：1；最小的偶数是：0；最小的质数是：2；最小的合数是：4； 7、分解质因数：把一个合数分解成多个质数相乘的形式。 用短除法分解质因数（一个合数写成几个质数相乘的形式）。 比如：30分解质因数是：（30=2×3×5） 8、互质数：公因数只有1的两个数，叫做互质数。 两个质数的互质数：5和7 一质一合的互质数：7和8
