exercises作名词时意为“运动；练习；运用；操练；礼拜；典礼”，作及物动词时意为“锻炼；练习；使用；使忙碌；使惊恐”，作不及物动词时意为“运动；练习”。                                    1.exercise用作名词的基本意思是“运动,锻炼”。指适用于正常人的一般性的以健身为目的的“体质锻炼”,也可指脑力方面的锻炼,还可指适用于运动员的“专业训练”。2.exercise作“练习,习题”解有时可用作定语; 作“使用,应用”解时,其结果常常是有效的; 作“演习,操练”解时常用复数。3.exercise用作动词的基本含义是反复地进行某一动作或一系列动作,以发展和加强某种能力,尤指为了身体健康或精力充沛而进行的活动。引申可表示“运用”“行使”或“实行”“执行”等。4.exercise既可用作不及物动词,也可用作及物动词。用作及物动词时,接名词或代词作宾语。                                    

运动，锻炼。首选是“容”这个字，其次是“美”。“容”包括脸、仪态、和修饰三层意思。“美”则具有形容词和动词的两层含义。exercise在美容里指运动，锻炼，美容一词可以从两个角度来理解。形容词表明的是美容的结果和目的是美丽的好看的；动词则表明的是美容的过程，即美化和改变的意思。

演习，名词。去除s 可译为运动。

exercise既是可数名词，同时也是不可数名词。exercise泛指“锻炼”时，做不可数名词，如：take exercise锻炼身体、take more exercise多锻炼；exercise表示“体操”或“练习（题）”时是可数名词，要用复数形式。如：do morning exercises（做早操）。 扩展资料 　　名词“exercise”可以和in搭配，意思是“有特定目的活动或事情”，此处是可数名词。 　　比如：“an exercise in team work一个锻炼团队配合活动”。 　　用法： 　　“Exercise”可以表示“一套特定的动作让身体变得更强壮和更健康”，此处的“exercise”是可数名词，通常在exercise之前会有另一个名词来说明是哪方面的.运动。 　　例句：I am doing knee exercises to help my recovery from a knee operation. 　　我正在做膝关节运动，帮助我做膝盖手术后的恢复。 　　“Exercise”作为名词时还可以表示“练习”，是可数名词，指“为了掌握某种技能而做的练习”。 　　例句：Try these online arithmetic exercises; they can improve students" maths skills. 　　试试这些网上算术练习，它们可以提高学生的数学技能。 　　复数形式“exercises”还会出现在军事话题中，意思是“操练”。 　　例：naval exercises海军操练 　　“Exercise”还有一个相对比较正式的含义，意思是“使用，运用”，不可数名词。 　　例：the exercise of self-control自我控制力的运 　　“Exercise”作为动词时的是“锻炼，运动”，指“为了身体健康而做运动”。 　　例句：John exercises every day to stay fit. 　　约翰每天都锻炼身体保持健康。 　　“Exercise”作为动词时的另一个含义是“让动物奔跑，锻炼”。 　　例句：Peter exercises his dog every morning. 　　彼得每天早上都出去遛狗。

cos30度=(√3)/2。cos是余弦值，所以余弦值=邻边÷斜边因为在三角形中，30°所对的直角边是斜边的一半。所以这个三角形的三边之比=1：√3：2。所以cos30°=邻边÷斜边=√3：2=√3/2。1、cos余弦函数，角A的邻边比斜边 叫做∠A的余弦，记作cosA（由余弦英文cosine简写得来），即cosA=角A的邻边/斜边（直角三角形）。2、直角三角形有一个角为直角的三角形称为直角三角形。在直角三角形中，与直角相邻的两条边称为直角边，直角所对的边称为斜边。直角三角形直角所对的边也叫作弦。若两条直角边不一样长，短的那条边叫作勾，长的那条边叫作股。3、与边角的关系：三角形三内角和等于180°；三角形的一个外角等于和它不相邻的两个内角之和；三角形的一外角大于任何一个和它不相邻的内角；三角形两边之和大于第三边，两边之差小于第三边；在同一个三角形内，大边对大角，大角对大边。

性质：1、所有的图形都通过（1,1）这点.(a≠0) a＞0时 图象过点（0,0）和（1,1）。2、当a大于0时，幂函数为单调递增的，而a小于0时，幂函数为单调递减函数。3、当a大于1时，幂函数图形下凸；当a小于1大于0时，幂函数图形上凸。4、当a小于0时，a越小，图形倾斜程度越大。5、显然幂函数无界限。6、a=0，该函数为偶函数 ｛x|x≠0｝。定义域和值域：当a为不同的数值时，幂函数的定义域的不同情况如下：如果a为负数，则x肯定不能为0，不过这时函数的定义域还必须根据a的奇偶性来确定，即如果同时p为奇数， 则x不能小于0，这时函数的定义域为大于0的所有实数；2.如果同时p为偶数，则函数的定义域为所有非零实数。当x为不同的数值时，幂函数的值域的不同情况如下：1、在x大于0时，函数的值域总是大于0的实数。2、在x小于0时，则只有同时q为奇数，函数的值域为非零的实数。而只有a为正数，0才进入函数的值域。

　　The Civil Rights Movement in the United States has been a long, primarily nonviolent struggle to bring full civil rights and equality under the law to all Americans. The movement has had a lasting impact on United States society, in its tactics, the increased social and legal acceptance of civil rights, and in its exposure of the prevalence and cost of racism.　　The American Civil Rights movement has been made up of many movements. The term usually refers to the political struggles and reform movements between 1945 and 1970 to end discrimination against African Americans and to end legal racial segregation, especially in the U.S. South.　　This article focuses on an earlier phase of the struggle. Two United States Supreme Court decisions—Plessy v. Ferguson, 163 U.S. 537 (1896), which upheld "separate but equal" racial segregation as constitutional doctrine, and Brown v. Board of Education, 347 U.S. 483 (1954) which overturned Plessy— serve as milestones. This was an era of stops and starts, in which some movements, such as Marcus Garvey"s Universal Negro Improvement Association, achieved great success but left little lasting legacy, while others, such as the NAACP"s painstaking legal assault on state-sponsored segregation, achieved modest results in its early years but made steady progress on voter rights and gradually built to a key victory in Brown v. Board of Education.　　After the Civil War, the U. S. expanded the legal rights of African Americans. Congress passed, and enough states ratified, an amendment ending slavery in 1865—the 13th Amendment to the United States Constitution. This amendment only outlawed slavery; it did not provide equal rights, nor citizenship. In 1868, the 14th Amendment was ratified by the states, granting African Americans citizenship. Black persons born in the U. S. were extended equal protection under the laws of the Constitution. The 15th Amendment was ratified in (1870), which stated that race could not be used as a condition to deprive men of the ability to vote. During Reconstruction (1865-1877), Northern troops occupied the South. Together with the Freedmen"s Bureau, they tried to administer and enforce the new constitutional amendments. Many black leaders were elected to local and state offices, and others organized community groups.　　Reconstruction ended following the Compromise of 1877 between Northern and Southern white elites. In exchange for deciding the contentious Presidential election in favor of Rutherford B. Hayes, supported by Northern states, over his opponent, Samuel J. Tilden, the compromise called for the withdrawal of Northern troops from the South. This followed violence and fraud in southern elections in 1876, which had reduced black voter turnout and enabled Southern white Democrats to regain power in state legislatures across the South. The compromise and withdrawal of Federal troops meant that white Democrats had more freedom to impose and enforce discriminatory practices. Many African Americans responded to the withdrawal of federal troops by leaving the South in what is known as the Kansas Exodus of 1879.　　The Radical Republicans, who spearheaded Reconstruction, had attempted to eliminate both governmental and private discrimination by legislation. That effort was largely ended by the Supreme Court"s decision in the Civil Rights Cases, 109 U.S. 3 (1883), in which the Court held that the Fourteenth Amendment did not give Congress power to outlaw racial discrimination by private individuals or businesses.　　Segregation　　The Supreme Court"s decision in Plessy v. Ferguson (1896) upheld state-mandated discrimination in public transportation under the "separate but equal" doctrine. While in the 20th century, the Supreme Court began to overturn state statutes that disfranchised African Americans, as in Guinn v. United States (1915), with Plessy, it upheld segregation that Southern states enforced in nearly every other sphere of public and private life.　　As Justice Harlan, the only member of the Court to dissent from the decision, predicted:　　If a state can prescribe, as a rule of civil conduct, that whites and blacks shall not travel as passengers in the same railroad coach, why may it not so regulate the use of the streets of its cities and towns as to compel white citizens to keep on one side of a street, and black citizens to keep on the other? Why may it not, upon like grounds, punish whites and blacks who ride together in street cars or in open vehicles on a public road or street? . . . .　　The Court soon extended Plessy to uphold segregated schools. In Berea College v. Kentucky, 211 U.S. 45 (1908), the Court upheld a Kentucky statute that barred Berea College, a private institution, from teaching both black and white students in an integrated setting. Many states, particularly in the South, took Plessy and Berea as blanket approval for restrictive laws, generally known as Jim Crow laws, that created second-class status for African-Americans.　　In many cities and towns, African-Americans were not allowed to share a taxi with whites or enter a building through the same entrance. They had to drink from separate water fountains, use separate restrooms, attend separate schools, be buried in separate cemeteries and even swear on separate Bibles. They were excluded from restaurants and public libraries. Many parks barred them with signs that read "Negroes and dogs not allowed." One municipal zoo went so far as to list separate visiting hours.　　The etiquette of racial segregation was even harsher, particularly in the South. African Americans were expected to step aside to let a white person pass, and black men dared not look any white woman in the eye. Black men and women were addressed as "Tom" or "Jane", but rarely as "Mr." or "Miss" or "Mrs." Whites referred to black men of any age as "boy" and a black woman as "girl"; both often were called by labels such as "nigger" or "colored."　　Less formal social segregation in the North began to yield to change.　　Jackie Robinson"s Major League Baseball debut, 1947　　Jackie Robinson was a sports pioneer of the Civil Rights Movement. Jackie Robinson is most well known for becoming the first African American to play professional sports in the major leagues. He is not often recognized as one of earliest public figures in the Civil Rights Movement. He debuted with the Brooklyn Dodgers of Major League Baseball on April 15, 1947. Jackie Robinson"s first major league game came one year before the U.S. Army was integrated, seven years before Brown v. Board of Education, eight years before Rosa Parks, and before Martin Luther King Jr. was leading the Civil Rights Movement. Jackie Robinson stepped into the spotlight before many of the most notable people in the Civil Rights Movement history. Every day he played, he was an example and role model for countless children and youths.　　Disfranchisement　　Main article: Disfranchisement after the Civil War　　By the turn of the century, white-dominated Southern legislatures disfranchised nearly all age-eligible African American voters through a combination of statute and constitutional provisions. While requirements applied to all citizens, in practice, they were targeted at blacks and poor whites, and subjectively administered. In addition, opponents of black civil rights used economic reprisals and sometimes violence in the 1880s to discourage blacks from registering to vote.　　Mississippi was the first state to have such constitutional provisions, such as poll taxes, literacy tests (which depended on subjective by white registrars), and complicated record keeping to establish residency, litigated before the Supreme Court. In 1898 the Court upheld the state, in Williams v. Mississippi. Other Southern states quickly adopted the "Mississippi plan", and from 1890-1908, ten states adopted new constitutions with provisions to disfranchise most blacks and many poor whites. States continued to disfranchise these groups for decades. Blacks were most adversely affected, as in many states black voter turnout dropped to zero. Poor whites were also disfranchised. In Alabama, for instance, by 1941, 600,000 poor whites had been disfranchised, and 520,000 blacks.[1]　　It was not until the 20th century that litigation by African Americans on such provisions began to meet some success before the Supreme Court. In 1915 in Guinn v. United States, the Court declared Oklahoma"s "grandfather law", to be unconstitutional. Although the decision affected all states that used the grandfather clause, state legislatures quickly devised new devices to continue disfranchisement. Each provision or statute had to be litigated separately. One device the Democratic Party began to use more widely in Southern states was the white primary, which served for decades to disfranchise the few blacks who managed to get past barriers of voter registration. Barring blacks from voting in the Democratic Party primaries meant they had no chance to vote in the only competitive contests. White primaries were not struck down by the Supreme Court until Smith v. Allwright in 1944.　　Criminal law and lynching　　In 1880, the United States Supreme Court ruled in Strauder v. West Virginia, 100 U.S. 303 (1880) that African Americans could not be excluded from juries. The late 19th century disfranchisement of blacks in the South, however, meant that blacks were routinely barred from jury service, as it was reserved for voters only. This left them at the mercy of a white justice system arrayed against them. In some states, particularly Alabama, the state used the criminal justice system to reestablish a form of peonage in the form of the convict-lease system. The state sentenced black males to years of imprisonment, which they spent working without pay. The state leased prisoners to private employers, such as Tennessee Coal, Iron and Railroad Company, a subsidiary of United States Steel Corporation, which paid the state for their labor. Because the state made money, the system created incentives for the jailing of more men, who were disproportionately black. It also created a system in which treatment of prisoners received little oversight.　　Extra-judicial punishment was even more brutal. During the last decade of the 19th century and the first decades of the 20th century, white vigilantes lynched thousands of black males, sometimes with the overt assistance of state officials, mostly within the South. No whites were charged with crimes in any of those massacres. Whites were, in fact, so confident of their immunity from prosecution for lynching that they not only photographed the victims, but made postcards out of the pictures.　　The Ku Klux Klan, which had largely disappeared after a brief violent career in the early years of Reconstruction, reappeared in 1915. It grew mostly in industrializing cities of the South and Midwest that underwent the most rapid growth from 1910-1930. Social instability contributed to racial tensions from severe competition for jobs and housing. People joined KKK groups who were anxious about their place in American society, as cities were rapidly changed by a combination of industrialization, migration of blacks and whites from the rural South, and waves of increased immigration from mostly rural southern and eastern Europe.[2]　　Initially the KKK presented itself as another fraternal organization devoted to betterment of its members. The KKK"s revival was inspired in part by the movie Birth of a Nation, which glorified the earlier Klan and dramatized the racist stereotypes concerning blacks of that era. The Klan focused on political mobilization, which allowed it to gain power in states such as Indiana, on a platform that combined racism with anti-immigrant, anti-Semitic, anti-Catholic and anti-union rhetoric, but also supported lynching. It reached its peak of membership and influence about 1925, declining rapidly afterward as opponents mobilized.[3]　　Segregated economic life and education　　In addition to excluding blacks from equal participation in many areas of public life, white society also kept blacks in a position of economic subservience or marginality. After widespread losses from disease and financial failures in the late 19th c., black farmers in the South worked in virtual economic bondage as sharecroppers or tenant farmers. Employers and labor unions generally restricted African Americans to the worst paid and least desirable jobs. Because of the lack of steady, well-paid jobs, relatively undistinguished positions, such as those with the Pullman Porter or as hotel doorman, became prestigious positions in black communities.　　The Jim Crow system that excluded African-Americans from many areas of economic life led to creation of a vigorous, but stunted economic life within the segregated sphere. Black newspapers sprang up throughout the North, while black owners of insurance and funeral establishments acquired disproportionate influence as both economic and political leaders.　　Continuing to see education as the primary route of advancement and critical for the race, many talented blacks went into teaching, which had high respect as a profession. Segregated schools for blacks were underfunded in the South and ran on shortened schedules in rural areas. Despite segregation in Washington, DC, by contrast, as Federal employees, black and white teachers were paid on the same scale. Outstanding black teachers in the North received advanced degrees and taught in highly regarded schools, which trained the next generation of leaders in cities such as Chicago, Washington, and New York.　　Education, in fact, w

按列表、描点和连线的方法，作出函数y=2分之1x的平方的图象，如下：扩展资料幂函数的讨论分析：由于x大于0是对α的任意取值都有意义的，因此下面给出幂函数在各象限的各自情况。可以看到：（1）所有的图像都通过（1，1）这点.（α≠0） α>0时 图象过点（0，0）和（1，1）。（2）单调区间：当α为整数时，α的正负性和奇偶性决定了函数的单调性：①当α为正奇数时，图像在定义域为R内单调递增；②当α为正偶数时，图像在定义域为第二象限内单调递减，在第一象限内单调递增；③当α为负奇数时，图像在第一三象限各象限内单调递减（但不能说在定义域R内单调递减）；④当α为负偶数时，图像在第二象限上单调递增，在第一象限内单调递减。当α为分数时，α的正负性和分母的奇偶性决定了函数的单调性：①当α>0，分母为偶数时，函数在第一象限内单调递增；②当α>0，分母为奇数时，函数在第一、三象限各象限内单调递增；③当α<0，分母为偶数时，函数在第一象限内单调递减；④当α<0，分母为奇数时，函数在第一、三象限各象限内单调递减（但不能说在定义域R内单调递减）；（3）当α>1时，幂函数图形下凹（竖抛）；当0<α<1时，幂函数图形上凸（横抛）。当α<0时，图像为双曲线。（4）在（0,1）上，幂函数中α越大，函数图像越靠近x轴；在（1，﹢∞）上幂函数中α越大，函数图像越远离x轴。（5）当α<0时，α越小，图形倾斜程度越大。（6）显然幂函数无界限。（7）α=2n（n为整数）,该函数为偶函数 {x|x≠0}。

解：1分米＝10厘米1分米×1分米＝10厘米×10厘米＝100平方厘米所以：100平方厘米等于一平方分米

1、守望中秋2、正文天，幽幽的叹息，泪水顺着眼角往下落，落在屋顶、路面和行人的衣襟，我的心也灰黯起来，站在窗前，默默的看着它，渐渐的不知是我感应了它，还是它影响了我，此时的天，拥着我，我，环着天，一起沉下去，沉下去。于是，雨不停的下着，我的心也在不停的往下沉没。掰开手指算算从现在到中秋只有六天了，这样的雨是否会下到六天之后，今年的中秋是否再见月圆，都已不重要了，我早已被这一份灰暗吞噬，在吞噬中迷醉。造物主是如此的神奇而不可思议，在千年的延迭中，总是那么分毫不差的在中秋这几日给人间送来完美，以补偿最不完美的人世。月圆时分，代表圆满、幸福、吉祥、如意，本该快快乐乐，可奇怪的是，从古到今的月圆时刻，倒无端的使人生出许多惆怅，那一份无法排遣的思乡怀人之情，在心里发酵，阵阵的酸楚，溢在纸间，压成千古的诗句与名篇。这大概缘于人世间真正的幸福与美满并不多，残缺的生活在想象的修补下，终于可以成就一段段人间神话吧。难怪东坡在对月时会感慨：人有悲欢离合，月有阴晴圆缺，此事古难全，未了，再添上一句，但愿人长久，千里共婵娟了！我从小就是一个很爱做梦的人，夜里的梦，在睁眼后总要回味片刻才起床，白日里也常常有片刻的空白，在思维的盲点上，勾画出绚丽多彩的图案，染得双眸也迷迷醉醉，母[作文https://Www.ZuoWEnHUi.Com]亲总是叹息的说，爱做梦的女孩子一生难找到幸福，因为总是分不清梦与现实的距离，母亲的话仅仅为我的梦添上了一丝忧郁与惴惴不安，我依然做着自己的梦，依然静静的修补着自己生活中的残缺，将他们轻轻的织就成一个个满月，挂在心灵至高的神殿。这些晶莹着的泡沫，随着岁月的增长，越加灿烂，也预示着我离现实越来越遥远，心中的负荷渐增，梦，也变得谨小慎微了，直到有一天，有位聪明的朋友告诉我：当你连梦都没有了的时候，你就什么都没有了，从此，我开始释然的做梦，开始释然的面对中秋的月，那一轮泫然的辉煌是最最完美的梦幻。美丽的梦幻总是易碎的，蓦然发现，我除了梦，竟已一无所有，捧着手里片片碎裂的梦幻，发现我早已走过了春天，燕子去了又来，叶子绿了又黄，又将中秋，年年岁岁月相似，岁岁年年人不同，此刻，沥沥的雨依然下着，掩去了我曾经追寻的痕迹，寻得太久了啊，找得太累，这个中秋，我将不再搜寻那模糊已久的人影，让他成为一张尘封的照片吧，放在阁楼的顶端，再将我也一并压成书签。这个中秋，不管是否有月，是否阴雨绵绵，只想喝下一碗孟婆汤，让我在尘世中单纯的快乐，单纯的走完留下的行程，或许，那一天，我将不会再哭，当清风撩起夜的衣角，擦着嫦娥眼角那滴凄然的泪，我将苍然的笑着，面对。

汉字如下：一声是“欻”。根据《现代汉语词典》及多部汉语字典中的解释，chua(一声)对应的汉字是“欻”，是个象声词，一般用来表示“急促的声响”，例句:欻的一下就把那张纸撕了。赏析：《唐韵》许物切《集韵》《韵会》《正韵》许勿切，

描写中秋节的好句好段1、中秋节自古以来就是我国最有人情、最诗情画意的一个节日，是仅次于春节的一个传统节日。它寄托着人们对生活无限的热爱和对美好生活的向往。2、中秋节这天早上，我、爸爸和妈妈一起去了姥姥家过中秋，我很高兴，路上我们去了“满意100”超市买月饼和各种零食，买月饼的人还真多呀，形形色色人头传动 ，大家都忙碌着挑选月饼，月饼的形式多样，有大有小、花纹不一、形状各异，真漂亮。3、中秋节我们全家一起去了顺峰山公园赏月游玩。望着天空中的一朵朵白云，不时地从月亮上滑过，好像成了月亮的毛巾，擦去了月亮脸上的灰尘。月亮变得更亮了，犹如一个光芒四射的金盘子，月光照在我们身上柔和似棉，令我们好不快活呀!4、月亮越升越高，已经在高空中看我们狂欢。它俯视大地，把光辉挥洒。洒在房顶、湖面、草地??细细地编织着一个幽雅迷离的梦境??5、又过了一会儿，微风吹来，云妈妈向北移了移身子。终于，月亮娃娃勇敢地望着我们，完全露出了她那胖乎乎、圆都都、笑眯眯的脸蛋儿。月亮娃娃散步在深蓝深蓝的夜空，给赏月的人们带来了光明、憧憬、欢乐??6、一年一度的中秋节又快来临了，人们又开始忙碌起来，为家人、朋友买月饼送礼物，带去他们最真诚的祝福。7、我一边吃着月饼一边仰望天空，只见天渐渐变成了深蓝色，有几颗稀稀的星星眨着明亮的眼睛。不一会，月亮透过云彩探出头来。起初，月光很浅很浅，温柔得犹如一块透明的白纱笼罩大地。慢慢地，月光越来越亮，最后，一轮圆圆的明月像一个巨大的银盘挂在高高的深蓝色的天空上，天空刹时变得如同白昼。8、我拿起了一块月饼吃了起来，我发现月饼里的白莲双黄馅还很好吃呢，我想起了一个神话传说，传说古代的时候，嫦娥下凡时在天间撒下了无数的月饼，而那天正好是农历八月十五日，所以就有了八月十五中秋节吃月饼的习惯。9、俗话说，中秋的月亮圆又圆。今天是中秋节，又可以欣赏到这圆圆的月亮了。
