outercourse的意思

Outercourse是一个起源于美国的术语，指的是一种six（和谐e）接触的方式，旨在避免直接性交而进行的其他six（和谐e）接触方式。这种类型的性行为涉及到一系列的身体接触，包括亲吻、爱抚、拥抱、按摩等，但不涉及到直接的six（和谐e）器官接触。Outercourse通常是一种安全six（和谐e）行为，可以避免性传播疾病和怀孕的风险，因此它也是一种受欢迎的避孕方法之一。但需要注意，它并不是百分之百的安全，因为某些疾病（如艾滋病）。此外，Outercourse也是一种增进情感联系的方式，在建立亲密关系方面具有广泛的应用。它可以帮助夫妻或者情侣建立更深层次的沟通和信任关系，增强二人之间的亲密感。Outercourse提供了多种形式的接触和体验，它不仅确保了six（和谐e）行为的安全性，还可以促进情感联系。但需要注意的是，Outercourse不是每个人都适合的six（和谐e）行为方式，对于选择Outercourse作为six（和谐e）行为的人，需要保证彼此的自愿、同意和尊重。

outercourse具体操作方法是口交、手交、肛门刺激等。英语（English）是印欧语系-日耳曼语族下的语言，由26个字母组合而成，英文字母渊源于拉丁字母，拉丁字母渊源于希腊字母，而希腊字母则是由腓尼基字母演变而来的。英语是国际指定的官方语言（作为母语），也是世界上最广泛的第一语言，英语包含约49万词，外加技术名词约30万个，是词汇最多的语言，也是欧盟以及许多国际组织以及英联邦国家的官方语言，拥有世界第三位的母语使用者人数，仅次于汉语和西班牙语母语使用者人数。英语由古代从丹麦等斯堪的纳维亚半岛以及德国、荷兰及周边移民至不列颠群岛的盎格鲁、撒克逊以及朱特部落的白人所说的语言演变而来，并通过英国的殖民活动传播到了世界各地。由于在历史上曾和多种民族语言接触，它的词汇从一元变为多元，语法从“多屈折”变为“少屈折”，语音也发生了规律性的变化。在19至20世纪，英国以及美国在文化、经济、军事、政治和科学在世界上的领先地位使得英语成为一种国际语言。如今，许多国际场合都使用英语做为沟通媒介。

新建两张表：表1：student 截图如下：表2：course 截图如下：（此时这样建表只是为了演示连接SQL语句，当然实际开发中我们不会这样建表，实际开发中这两个表会有自己不同的主键。）一、外连接外连接可分为：左连接、右连接、完全外连接。1、左连接 leftjoin或leftouterjoinSQL语句：select*fromstudentleftjoincourseonstudent.ID=course.ID执行结果：左外连接包含leftjoin左表所有行，如果左表中某行在右表没有匹配，则结果中对应行右表的部分全部为空(NULL).注：此时我们不能说结果的行数等于左表数据的行数。当然此处查询结果的行数等于左表数据的行数，因为左右两表此时为一对一关系。2、右连接 rightjoin或rightouterjoinSQL语句：select*fromstudentrightjoincourseonstudent.ID=course.ID执行结果：右外连接包含rightjoin右表所有行，如果左表中某行在右表没有匹配，则结果中对应左表的部分全部为空(NULL)。注：同样此时我们不能说结果的行数等于右表的行数。当然此处查询结果的行数等于左表数据的行数，因为左右两表此时为一对一关系。3、完全外连接 fulljoin或fullouterjoinSQL语句：select*fromstudentfulljoincourseonstudent.ID=course.ID执行结果：完全外连接包含fulljoin左右两表中所有的行，如果右表中某行在左表中没有匹配，则结果中对应行右表的部分全部为空(NULL)，如果左表中某行在右表中没有匹配，则结果中对应行左表的部分全部为空(NULL)。二、内连接 join 或innerjoinSQL语句：select*fromstudentinnerjoincourseonstudent.ID=course.ID执行结果：innerjoin是比较运算符，只返回符合条件的行。此时相当于：select*fromstudent,coursewherestudent.ID=course.ID三、交叉连接crossjoin1.概念：没有WHERE子句的交叉联接将产生连接所涉及的表的笛卡尔积。第一个表的行数乘以第二个表的行数等于笛卡尔积结果集的大小。SQL语句：select*fromstudentcrossjoincourse执行结果：如果我们在此时给这条SQL加上WHERE子句的时候比如SQL:select*fromstudentcrossjoincoursewherestudent.ID=course.ID此时将返回符合条件的结果集，结果和innerjoin所示执行结果一样。四、两表关系为一对多，多对一或多对多时的连接语句当然上面两表为一对一关系，那么如果表A和表B为一对多、多对一或多对多的时候，我们又该如何写连接SQL语句呢？其实两表一对多的SQL语句和一对一的SQL语句的写法都差不多，只是查询的结果不一样，当然两表也要略有改动。比如表1的列可以改为：SnoNameCno表2的列可以改为：CnoCName这样两表就可以写一对多和多对一的SQL语句了，写法和上面的一对一SQL语句一样。下面介绍一下当两表为多对多的时候我们该如何建表以及些SQL语句。新建三表：表A: student截图如下：表B: course截图如下：表C: student_course截图如下：一个学生可以选择多门课程，一门课程可以被多个学生选择，因此学生表student和课程表course之间是多对多的关系。当两表为多对多关系的时候，我们需要建立一个中间表student_course，中间表至少要有两表的主键，当然还可以有别的内容。SQL语句：selects.Name,C.Cnamefromstudent_courseasscleftjoinstudentassons.Sno=sc.Snoleftjoincourseasconc.Cno=sc.Cno执行结果：此条SQL执行的结果是学生选课的情况。

本教程为大家介绍SQL中的多表查询，下面我们来看看具体实例吧。新建两张表：表1：student 截图如下：表2：course 截图如下：(此时这样建表只是为了演示连接SQL语句，当然实际开发中我们不会这样建表，实际开发中这两个表会有自己不同的主键。)一、外连接外连接可分为：左连接、右连接、完全外连接。1、左连接 left join 或 left outer joinSQL语句：select * from student left join course on student.ID=course.ID执行结果：左外连接包含left join左表所有行，如果左表中某行在右表没有匹配，则结果中对应行右表的部分全部为空(NULL).注：此时我们不能说结果的行数等于左表数据的行数。当然此处查询结果的行数等于左表数据的行数，因为左右两表此时为一对一关系。2、右连接 right join 或 right outer joinSQL语句：select * from student right join course on student.ID=course.ID执行结果：右外连接包含right join右表所有行，如果左表中某行在右表没有匹配，则结果中对应左表的部分全部为空(NULL)。注：同样此时我们不能说结果的行数等于右表的行数。当然此处查询结果的行数等于左表数据的行数，因为左右两表此时为一对一关系。3、完全外连接 full join 或 full outer joinSQL语句：select * from student full join course on student.ID=course.ID执行结果：完全外连接包含full join左右两表中所有的行，如果右表中某行在左表中没有匹配，则结果中对应行右表的部分全部为空(NULL)，如果左表中某行在右表中没有匹配，则结果中对应行左表的部分全部为空(NULL)。二、内连接 join 或 inner joinSQL语句：select * from student inner join course on student.ID=course.ID执行结果：inner join 是比较运算符，只返回符合条件的行。此时相当于：select * from student,course where student.ID=course.ID三、交叉连接 cross join1.概念：没有 WHERE 子句的交叉联接将产生连接所涉及的表的笛卡尔积。第一个表的行数乘以第二个表的行数等于笛卡尔积结果集的大小。SQL语句：select * from student cross join course执行结果：如果我们在此时给这条SQL加上WHERE子句的时候比如SQL:select * from student cross join course where student.ID=course.ID此时将返回符合条件的结果集，结果和inner join所示执行结果一样。四、两表关系为一对多，多对一或多对多时的连接语句当然上面两表为一对一关系，那么如果表A和表B为一对多、多对一或多对多的时候，我们又该如何写连接SQL语句呢?其实两表一对多的SQL语句和一对一的SQL语句的写法都差不多，只是查询的结果不一样，当然两表也要略有改动。比如表1的列可以改为：Sno Name Cno表2的列可以改为：Cno CName这样两表就可以写一对多和多对一的SQL语句了，写法和上面的一对一SQL语句一样。下面介绍一下当两表为多对多的时候我们该如何建表以及些SQL语句。新建三表：表A: student 截图如下：表B: course 截图如下：表C: student_course 截图如下：一个学生可以选择多门课程，一门课程可以被多个学生选择，因此学生表student和课程表course之间是多对多的关系。当两表为多对多关系的时候，我们需要建立一个中间表student_course，中间表至少要有两表的主键，当然还可以有别的内容。SQL语句：select s.Name,C.Cname from student_course as sc left join student as s on s.Sno=sc.Sno left join course as c on c.Cno=sc.Cno执行结果：此条SQL执行的结果是学生选课的情况。

【答案】：本题可以通过新建一个程序来实现统计。可以使用“查询设计器”构造以下的SELECT语句：SELECT Student.姓名;FROM Course INNER JOIN Score1;INNER JOIN Student ;ON Student.学号 = Score1.学号 ;ON Course.课程号 = Score1.课程号;WHERE Course.课程号 = score1.课程号;GROUP BY Student.姓名;INTO CURSOR TempSELECT COUNT(姓名) AS 学生人数 FROM Temp;INTO TABLE New_table$本题的主要考核点是SQL查询语句的使用。可以使用“查询设计器”构造以下的SELECT语句：SELECT Course.课程名,Course.开课单位;FROM Course LEFT OUTER JOIN Score1;LEFT OUTER JOIN Student ;ON Student.学号 = Score1.学号 ;ON Course.课程号 = Score1.课程号;WHERE Course.课程号 !=Score1.课程号;ORDER BY Course.课程名;INTO TABLE New_table2.dbf

I want to see at the beginning of the book will be put aside until LG will turn off the lights, I reluctantly closed the book will be, on the pillow. After the upper and lower on the waiting out. Left to right, and so on and so on, finally published in late March. But some have been busy in a mess of things inefficient, it was not until today that it will be finished in one breath. Chen Zhao I VE NEVER BEEN TO ME background music, there is a time for tears poured like to, but not the end. After reading each of these excellent description of the reality of work, will the hearts of many nameless ray of Tim and the vicissitudes of depression, anxiety felt in a number of old. Today is the lower part of the time, tell the truth on the upper part of the two characters have been doing is not very clear, but also the image. I read the work, there was an emphasis on the secret fate of the characters I draw, but not this time, Lee and Song Gang head of the two figures, one I do not focus. I watch them from the cold of the last century came a confusion of the times, has come to today. The last century flavor of the times I can only learn from books, posters, slogans, of procession and of the struggle, will be criticized and denounced, writing materials, such as those words again and again in the emergence of many well-known writers brushes, although the description of the different characters, but the scene More or less the same. I never could not understand what it is, it also can not speak. Yu Hua in the new so-called out for the first time to face the reality of the novel, but I really see the reality of the shadow. Beauty, advertising, as well as the sale of counterfeit charlatan Lee was also involved in a head restaurant, bath center, real estate and so on, finally, he has also set up a holding company, dividends, the economic phenomena are related to him, but For restaurants, bath and how the operation has not written, the author may not want to turn it into a description of the operation of commercial fiction. Song Li Gang and the fate of skinheads in the novel seems to be deliberately arranged very strange. Song Gang honest, introverted, loyal, kind-hearted, as in the ordinary course of such a person, no matter at which age should be a good person reported good, there should be a good end, but even 20 years of marriage but no children born, and finally Wogui suicide; Lee and skinheads, rude, and even direct a small rogue, but his loyalty, justice, life is a balance sum, do not lose out not fooled, do not account for other people less, the hard way, even if he is big business , We should not be the traditional self-Ren Jun is the tooth, in those days, his 14-year-old girl peep on the bottom, was arrested last march, but he just die disaster; his father with no mother, Yu Zhao-he-is a very, very good to him, dead set on the Song of Steel, the two brothers Xiangyiweiming into a new era. The new era of Song Gang-wen only appearance, Lin Hong-face after 20 years of marriage have been an honest day"s work when the work honestly, the laid-off workers find jobs on the honest, and even the nature of things Are honest, every time not more than 2 minutes; Lee skinheads, are not always honest, the factory does not stay honest, it is necessary to do business out of business did not make the less other people"s money is not honest, to the county When arguing with the Government to return to the factory manager. Even in front of the county government does not stay honest, while also doing Shou Polan protest against the side of the business. When money is not honest, to harass groups of red-lin, the money is not honest, direct people to receive their own bed. He is not honest, they just have to let Lin Hung climax, but also one after another, not only the case, Lin also hong them to realize a happy, and addicted to it. This is not the old saying goes, "not a bad man, a woman does not love"? Song honest with steel-off after the charlatan hard to run out of the arena in 2012, made himself a disease, the last to get 30,000 of the money, his wife told other people run their own suicide Wogui; not Lee"s honest head Shi Polan up in front of the county government has become a multimillionaire, was the last to get its red-lam on the bed, the old veteran still on the aerospace spacecraft into outer space, and Song Gang at this time only one holding the ashes. Tears. People do not know for himself or for life, as fate. Yu Hua to feel that life is too well written and the arts. Lu said that the hybrid get all kinds of people, merged into one single. Li Yu Hua"s works in the fate of skinheads too good, and why he always Juechufengsheng, and Song Gang why no one good chance? Song Gang sp again, will not have a child on Health Come see! Why then do people deliberately run. After reading the book, the general feeling is that to be honest and the people who are admired, sigh, but not dishonest to the people it is. However, it does not correspond to the life of me. Over the years, I have always believed that the forces of evil are only temporary, honest people who suffer only temporary, as time goes by, honest people who will ultimately well reported. Honest people who will ultimately end up well. The villain who is also a natural subject of retribution. Lee is not a bad head, he is not surprised that I am wealthy, so some people do have, the opportunity to encounter a good, rich oil also for the benefit of the party. But Song Gang Ho As to the fate of them suffer so much? In order to compare before and after it? Lee is to head comparison? Yu Hua in the description of the phenomenon of social satire, when the use of humor has matured, but the social phenomenon is superficial and does not make a more extensive analysis. Fuli Chang further that the 14 loyal to me very strange feeling. Three silly fool on it, with a total of the other people are not stupid, but this time the four loyal like the Cultural Revolution left behind a few relics of the statue until the end of the work, their position has changed. World Wind is next, Renxinbugu. The only difference is that Lee"s head the welfare of the people regardless of the factory head Li is good or bad, as long as he went to Fuli Chang, the factory of those with disabilities, as always, on his support. He spoke, they applauded; he needs to build momentum, they line up on the parade; he did not even eat, and they asked him to eat on the pool surface, and let him eat up all the other people in the next Tunkou Shui. Yu Hua is perhaps left us traces the history of it. The author may still remember that the era has gone it!请从上面摘抄一点吧

题.具有世界地质科学意义. ue000 其二,园区东部野寨一牌楼断裂是全球着名的郯庐 ue000 断裂带的南延部分,构成大别山超高压变质带与潜山盆 ue000 地的边界断裂.郯庐断裂带的多期活动历史,对大别山 ue000 超高压变质带的折返,天柱山花岗岩的成岩,成景过程 ue000 以及古近纪哺乳类动物化石的形成具有重要的控制作 ue000 用. ue000 其三,园区不仅是举世闻名的大别山超高压变质带 ue000 立典之地,而且也是中生代岩浆活动最为强烈的地区之 ue000 一 ue000 .天柱山花岗岩形成于中生代,就位于大别山超高压 ue000 变质带的东端与郯庐断裂交汇部位,其成岩作用经历了 ue000 板块俯冲和碰撞以及碰撞后的拉张松弛过程.研究天柱 ue000 山花岗岩的物质来源及成因机制,对探讨大别造山带碰 ue000 撞后深部地壳的地球化学性质和中国东部燕山期大规 ue000 模构造热事件的成因机制具有重要的意义. ue000 其四,同区主体地貌属于由中生代花岗岩构成的峰 ue000 林峰丛地貌.花岗岩微地貌类型多样,几乎包罗了世界 ue000 上所有的花岗岩风景区的地貌景观,奇峰,怪石,洞穴, ue000 峡谷等,其中以花岗岩崩塌及崩塌堆叠形成的神秘谷洞 ue000 穴地貌景观典型独特,堪称世界一绝.已被陈安泽命名 ue000 为”天柱山型”崩塌叠石地貌景观【131,因而具有突出的地 ue000 貌学价值. ue000 其五,园区产出丰富的古新世哺乳动物化石,具有 ue000 亚洲的地方性特色,在研究新生代初期哺乳动物演化方 ue000 面具有独特的地位.目前在国外古新世哺乳动物发现最 ue000 多,研究程度最高的是北美,但潜山古新世哺乳动物明 ue000 显区别于北美及欧洲等地的化石.在亚洲其他国家,只 ue000 有蒙古有较丰富的古新世哺乳动物产出,但其时代是古 ue000 新世最晚期,明显晚于安徽潜山及中国南方其他地区. ue000 同时,其动物群组成中也没有大量古老类群的原始种 ue000 类,与潜山古新世动物群差别相当显着.国内同期可以 ue000 比较的古新世动物群以安徽潜山,广东南雄和江西池江 ue000 最为着名.与南雄和池江相比,潜山的古新世,$-9L 动物 ue000 群在生物演化上有着独特意义. ue000 潜山发现的最有意义的化石当首推东方晓鼠 ue000 (HeomysorientalisLi,1977)和模鼠兔(MimotonawanaLi, ue000 1977,robustaLi,1977),它们分别代表了啮齿类(鼠) ue000 和兔形类(兔)的祖先类型.”东方晓鼠”即取意为它的 ue000 “发现对啮齿类动物起源的问题犹如东方旭El,朦胧欲 ue000 晓了”.相关研究一致认为晓鼠和模鼠兔分别为啮齿类 ue000 和兔形类的起源提供了可靠的化石证据,并进一步证实 ue000 了啮齿类和兔形类是同源的,都应起源于以潜山为代表 ue000 的亚洲地区.”潜山安徽龟”化石是我国迄今发现的最早 ue000 色鳌类地史记录.天柱山地质公园从而被公认为”亚洲 ue000 哺乳动物的发源地之一,古脊椎动物化石的宝地”. ue000 2-2 科普教育价值 ue000 SHANGHAIGEOLOGY 上海地质- ue000 园区所处的独特的大地构造位置,漫长而复杂的地 ue000 质演化历史,丰富而典型的地质遗迹,大别山超高压变 ue000 质带的经典地段,全球古新世啮齿类与兔形类哺乳动物 ue000 起源地,独具特色的花岗岩地貌,不仅为中外地质学家 ue000

渐演变形成的”峰雄,石奇,崖险,岭秀,洞幽”奇特地貌, ue000 与变幻莫测的云海,佛光等气象景观,丰富的动植物以 ue000 及多姿多彩水文地质遗迹的完美结合,造就挺拔峥嵘, ue000 风姿绰约,变幻莫测的万千气象,犹如一轴气韵生动的 ue000 立体画卷,给人以强烈的视觉冲击和美学享受. ue000 天柱山的美学价值表现在: ue000 各种景观有机组合,高度的和谐,形成统一而连续 ue000 的构图格局,有着三度空间的可感形象,具有分明的层 ue000 次感和韵律美,具极高的艺术观赏. ue000 天柱山位于中国南北过渡地带,既有北山之雄,又 ue000 有南岭之秀,雄奇灵秀系于一身,故给人以博彩美一峰 ue000 体硕大,给人以壮美;植被良好,给人以秀美;怪石众多, ue000 给人以奇美;洞穴深邃,给人以幽秘之美. ue000 天柱山的雄峰,奇石,洞穴,瀑布等景观丰富多样, ue000 令人目不暇接.而每一景,一物又都显示出自然的形态 ue000 美,特别是堪称中国一绝的天柱巧石,千姿百态如人如 ue000 兽,如诗如画,凸显个性美,奇峰地貌,云海奇观,松竹清 ue000 新,皆出神人化,美不胜收. ue000 天柱山天生丽质,美在自然,由于生态与原貌保存 ue000 较好,至今其峰崖岭隘,草木花卉,沟谷溪流无不呈现出

不是一也不是二 应该是f(x)=λe^(-λx) 那个积分上限应该是正无穷大.原函数是F（x）=-e^(-λx) 带入正无穷,等于0 带入1/λ,等于-e^(-1).相减,就是答案了

I"ll See to the RestA guard was about to signal his train to start when he saw an attractive girl standing on the platform by an open door, talking to another pretty girl inside the carriage. "Come on, miss!" he shouted. "Shut the door, please!" "Oh, I just want to kiss my sister goodbye," she called back. "You just shut that door, please," called the guard, "and I"ll see to the rest." 其余的事由我负责一位车上的列车员刚发出信号让火车启动，这时他看见一位很漂亮的姑娘站在站台上一节打开的车厢门旁边，跟车厢里另一位漂亮姑娘在说话。 “快点，小姐!”他喊道：“请把门关上。” “噢，我还没有和妹妹吻别呢。”她回答道。 “请把门关上好了，”列车员说：“其余的事由我负责。”Sleeping PillsBob was having trouble getting to sleep at night. He went to see his doctor, who prescribed some extra-strong sleeping pills. Sunday night Bob took the pills, slept well and was awake before he heard the alarm. He took his time getting to the office, strolled in and said to his boss: "I didn"t have a bit of trouble getting up this morning." "That"s fine," roared the boss, "but where were you Monday and Tuesday?" 安眠药鲍勃晚上失眠。他去看医生，医生给他开了一些强力安眠药。 星期天晚上鲍勃吃了药，睡得很好，在闹钟响之前就醒了过来。他到了办公室，遛达进去，对老板说：“我今天早上起床一点麻烦都没有。” “好啊!”老板吼道，“那你星期一和星期二到哪儿去了？” A SmugglarThe suspicious-looking man drove up to the border, where he was greeted by a sentry. When the guard looked in the trunk, he was surprised to find six sacks bulging at the seams. "What"s in here?" he asked. "Dirt," the driver replied. "Take them out," the guard instructed. "I want to check them." Obliging, the man removed the bags, and sure enough, each one of them contained nothing but dirt. Reluctantly, the guard let him go. A week later the man came back, and once again, the sentry looked in the truck. "What"s in the bags this time?" he asked. "Dirt, more dirt." said the man. Not believing him, the guard checked the sacks and, once again, he found nothing but soil. The same thing happened every week for six months, and it finally became so frustrating to the guard that he quit and became a bartender. Then one night, the suspicious-looking fellow happened to stop by for a drink. Hurrying over to him, the former guard said, "Listen, pal, drinks are on the house tonight if you"ll do me a favor: Just tell me what the hell you were smuggling all that time." Grinning broadly, the man leaned close to the bartender"s ear and whispered, "Cars." 走私犯一个形迹可疑的人开车来到边境，哨兵迎了上去。哨兵在检查汽车行李箱时，惊奇地发现了六个接缝处鼓得紧绷绷的大口袋。 “里面装的是什么？”他问道。 “土。”司机回答。 “把袋子拿出来”，哨兵命令道：“我要检查。” 那人顺从地把口袋搬了出来。确实，口袋里除了土以外，别无他特。哨兵很不情愿地让他通过了。 一周后，那人又来了，哨兵再次检查汽车上的行李箱。 “这次袋子里装的是什么？”他问道。 “土，又运了一些土。”那人回答。 哨兵不相信，对那些袋子又进行了检查，结果发现，除了土以外，仍旧一无所获。 同样的事情每周重演一次，一共持续了六个月。最后，哨兵被弄得灰心丧气，干脆辞职去当了酒吧侍者。有天夜里，那个形迹可疑的人碰巧途经酒吧，下车喝酒。那位从前的哨兵急忙迎上前去对他说，“我说，老兄，你要是能帮我一个忙，今晚的酒就归我请客。你能不能告诉我，那段时间你到底在走私什么东西？” 那人俯身过来，凑近侍者的耳朵，裂开嘴笑嘻嘻地说：“汽车。”Skunk"We have a skunk in the basement," shrieked the caller to the police dispatcher. "How can we get it out?" "Take some bread crumbs," said the dispatcher, "and put down a trail from the basement out to the back yard. Then leave the cellar door open." Sometime later the resident called back. "Did you get rid of it?" asked the dispatcher. "No," replied the caller. "Now I have two skunks in there!" 臭 鼬“我们的地下室里有一只臭鼬，”打电话的人对警察调度员尖叫道。“我们怎样才能把它弄出来？” “弄一些面包屑，”调度员说，“从地下室往外铺一条小道直到后院。然后将地下室的门打开。” 一段时间后，那位居民又将电话打了回来。“你们将它弄出来了吗？”调度员问。 “没有，”打电话的人答道，“现在那儿有两只臭鼬了。”PatienceAngler: You"ve been watching me for three hours now. Why don"t you try yourself? Onlooker: I haven"t got the patience. 耐 性垂钓者：你已经盯着看了三个小时了，你干嘛不自己亲自钓呢？ 旁观者：我没那耐性。Bedtime PrayersJulie was saying her bedtime prayers. "Please God," she said, "make Naples the capital of Italy. Make Naples the capital of Italy." Her mother interrupted and said. "Julie, why do you want God to make Naples the capital of Italy?" And Julie replyed, "Because that"s what I put in my geography exam!"睡前祷告词朱莉叶在做睡前祷告。“上帝，求求你，”她说，“让那不勒斯成为意大利的首都吧。” 妈妈打断她的话说：“朱莉叶，为什么求上帝让那不勒斯成为意大利的首都呢？” 朱莉叶回答道：“因为我在地理考卷上是这样写的。” Things Have Been OkayA young couple were becoming anxious about their four-year-old son, who had not yet talked. They took him to specialists, but the doctors found nothing wrong with him. Then one morning at breakfast the boy suddenly blurted, "Mom, the toast is burned." "You talked! You talked!" Shouted his mother. "I"m so happy! But why has it taked this long?" "Well, up till now," Said the boy, "things have been okay." 一切都正常一对年轻夫妇有个儿子，已经四岁了，还没有开品说话，他们对此深感焦虑。他们带他去找专家诊治，但医生们总觉得他没有毛病。后来有一天早上吃早餐时，那孩子突然开口了：“妈妈，面包烤焦了。” “你说话了!你说话了!”他母亲叫了起来。“我太高兴了!但为什么花了这么长的时间呢？” “哦，在这之前，”那男孩说，“一切都很正常。” That"s WhyJimmy started painting when he was three years old, and when he was five, he was already very good at it. He painted many beautiful and interesting pictures, and people paid a lot of money for them. They said, "This boy"s going to be famous when he"s little older, and then we"re going to sell these pictures for a lot more money." Jimmy"s pictures were different from other people"s because he never painted on all of the paper. He painted on half of it, and the other half was always empty. "That"s very clever," everyone said, "Nobody else does that!" One day somebody bought one of Jimmy"s pictures and then said to him, "Please tell me this, Jimmy. Why do you paint on the bottom half of your pictures, but not on the top half?" "Because I"m small," Jimmy said, "and my burshes don"t reach very high." 原来如此吉米三岁开始画画，五岁时已经画得很好了。他画了很多美丽而有趣的画，人们出高价购买。他们说，“这个孩子长大一点肯定会出名，我们可以靠这些画大赚一笔。” 吉米的画与众不同。因为他从来不在整张纸上作画。他只画一半的纸，而另一半他总空着。 “构思多么巧妙啊!”大家都说，“从来没有人这么做过。” 有一天，一个人买了吉米的画，然后问他：“请告诉我，吉米，你为什么总是在纸的下半部分画画，而不是在纸的上半部分？” 吉米说，“因为我个头小，够不着上面。” A Trip to DisneyOn a trip to Disney World in Florida, my husband and I adn our two children devoted ourselves wholeheartedly to the wonders of this attraction. After three exhausting days, we headed for home. As we drove away, our son waved and said, "Good-by, Mickey." Our daughter waved and said, "Good-by, Minnie." My husband waved, rather weakly, and said, "Good-by, Money." 迪斯尼之族弗罗里达州的迪斯尼乐园是一个迷人的地方。一次我和丈夫以及两个孩子前往旅游，我们全身心地沉醉在它的各种奇观之中。精疲力竭地玩了三天之后，我们要回家了。 当我们驱车离开时，儿子挥手说：“再见，美奇。” 女儿挥着手说，“再见，美妮。” 丈夫也有气无力地挥了挥手，说道：“再见，美元。” A Fine MatchOne day a lady saw a mouse running across her kitchen floor. She was very afraid of mouse, so she ran out of the house, got into a bus and went to the shops. There she bought a mousetrap. The shopkeeper said to her, "Put some cheese in it and you will soon catch that mouse." The lady went home with her mousetrap, but when she looked in her cupboard, she could not find any cheese in it. She did not want to go back to the shop, because it was very late, so she cut a picture of some cheese out of a magazine and put that in the trap. Surprisingly, the picture of the cheese was quite successful! When the lady came down to the kitchen the next morning she found a picture of a mouse in the trap beside the picture of the cheese! 势均力敌有一天某位女士看到一只老鼠在自家的厨房地板上窜过。她很害怕老鼠，所以她冲出屋子，搭上了公共汽车直奔商店。在那儿，她买了一只老鼠夹。店主告诉她：“放点奶酪在里面，很快你就会逮住那只老鼠的。” 这位女士带着鼠夹回到家里，但她没有在碗橱里找到奶酪。她不想再回到商店里去，因为已经很晚了。于是，她就从一份杂志中剪下一幅奶酪的图片放进了夹子。 令人称奇的是，这画有奶酪的图片竟然奏效了!第二天早上，这位女士下楼到厨房时，发现鼠夹里奶酪图片旁有一张画有老鼠的图片! Prepare YourselfA story around campus has it taht a student once sent a telegram to his parents reading: "Mom - flunked all courses. Kicked out of school. Prepare Pop." Two days later he received a response: "Pop prepared. Prepare yourself." 自己做好准备校园里流传着这样的故事：一个学生一次给父母拍了一份电报，上面写着：“妈妈－我所有功课都不及格，被学校开除。让爸爸做好准备。” 两天以后，他收到了回电：“爸爸已准备好。你自己做好准备吧!” Why he couldn"t leave? There was a meeting with a large number of people. At first the speaker was very interesting, but as time went on, he became very boring. Finally when he was through, there was only one man sitting in the large room. The speaker walked up to the man and said, "Thank you for hearing me out when all the others left the room." "Oh! Don"t mention it!" replied the man, "I cannot leave because I am the next speaker."他为什么不走? 在一个很多人参加的会议中,刚开始演讲者说得非常有趣,但渐渐地,他说得越来越令人厌烦.结果,当会议结束的时候,大会议室里只剩一个人了. 演讲者走过去跟那个人说:”谢谢你,其他人都走了,只有你还在听我说.” “噢,别客气.”那个人回答说,”我不走,是因为我是下一位演讲者!”
