It is no easy job to educate a people who have been told over centuries that they were inferior and of no importance to see that they are humans, the same as any other people. 2. Psychological freedom, a firm sense of self-esteem, is the most powerful weapon against the long night of physical slavery. If you break the mental shackles imposed on you by white supremacists, if you really respect yourself, thinking that you are a Man, equal to anyone else, you will be able to take part in the struggle against racial discrimination. 3. The Negro will only be free when he reaches down to the inner depths of his own being and signs with the pen and ink of assertive manhood his own emancipation proclamation. The liberation of mind can only be achieved by the Negro himself/herself. Only when a negro is fully convinced that he/she is a Man/Woman and is not inferior to anyone else, can he/she throw off the manacles of self-abnegation and become free. 4. Power at its best is love implementing the demands of justice, and justice at its best is power correcting everything that stands against love. Power in its best form of function is the carrying out of the demands of justice with love and justice in the best form of function is the overcoming of everything standing in the way of love with power. ability and 5.

A person was poor because he was lazy and not hard-working and lacked a sense of right and wrong. 7. It is not the work of slaves driven to their tasks either by the task, by the taskmaster, or by animal necessity.

It is no easy job to educate a people who have been told over centuries that they were inferior and of no importance to see that they are humans, the same as any other people. 2.Psychological freedom, a firm sense of self-esteem, is the most powerful weapon against the long night of physical slavery. If you break the mental shackles imposed on you by white supremacists, if you really respect yourself, thinking that you are a Man, equal to anyone else, you will be able to take part in the struggle against racial discrimination. 3.The Negro will only be free when he reaches down to the inner depths of his own being and signs with the pen and ink of assertive manhood his own emancipation proclamation. The liberation of mind can only be achieved by the Negro himself/herself.

Power in the best form of function is the carrying out of the demands of justice with love and justice in the best form of function is the overcoming of everything standing in the way of love with power. 5.At that time economic status was considered the measure of the individual’s ability and talents. At that time, the way to evaluate how capable and resourceful a person was to see how much money he had made (or how wealthy he was). 6.…the absence of worldly goods indicated a want of industrious habits and moral fiber. A person was poor because he was lazy and not hard-working and lacked a sense of right and wrong. 7.It is not the work of slaves driven to their tasks either by the task, by the taskmaster, or by animal necessity. This kind of work cannot be done by slaves who work because the work has to be done, because they are forced to work by slave-drivers or because they need to work in order to be fed and clothed. 8.…when the unjust measurement of human worth on the scale of dollars is eliminated. …when the unfair practice of judging human value by the amount of money a person has is done away with. 9.He who hates does not know God, but he who has love has the key that unlocks the door to the meaning of ultimate reality. Those who harbor hate in their hearts cannot grasp the teachings of God. Only those who have love can enjoy the ultimate happiness in Heaven. 10.Let us be dissatisfied until America will no longer have a high blood pressure of creeds and an anemia of deeds. Let us be dissatisfied until America no longer only talk about racial equality but is unwilling or reluctant to take action to end such evil practice as racial discrimination.

In c语言课后习题答案 第二章习题 2.什么叫做结构化算法？为什么要提倡结构化算法？ 答：结构化算法是由一些基本结构顺序组成的。在基本结构之间不存在向前或向后的跳转,流程的转移只存在于一个基本的结构范围内。一个非结构化的算法可以用一个等价的结构化算法代替,其功能不变。 跟结构化算法比较起来,非结构化算法有以下缺点： 流程不受限制的随意转来转去,使流程图豪无规律使人在阅读的时候难以理解算法的逻辑.难以阅读,也难以修改，从而使算法的可靠性和可维护性难以保证。 4. 第三章习题 １．#include float p,p1,r=0.09; scanf("%u",&n); p=pow(1+r,n); p1=(p-1)*100; printf("%5.2f%%\n",p1); } 运行结果：输入，回车，见结果： ２．#include 1、他这次考试的失败使他意识到定期复习功课的重要。 His failure in the exam has made him aware of the importance of reviewing his lessons regularly. 2、请一定不要忘记离家前你父母对你说过的话。 Be sure not to forget what your parents said to you before you left home. 3、我确信她的英语知识对这项工作来说是足够的了。 I'm sure her knowledge of English is adequate for the job. 4、这篇文章的目的是告诉学生怎样培养良好的学习习惯。 The purpose of this article is to tell the students how to develop good study habits. 5、在当今时代，人们越来越多地依靠计算机(computers)来解决各种各样的问题。 In our age, people depend more and more on computers to solve various kinds of difficult problems. 6、略读不仅可以帮助你对将要阅读的东西有所了解，还可以帮助你读得快些，提高你的阅读理解力。Skimming not only helps you get some idea of what you are going to read but also helps you read faster and improve your comprehension. 7、有些人以为男孩子比女孩子聪明。然而，事实未必如此。 Some people believe that boys are cleverer than girls.
