三角函数的图像的对称性

纵观近几年的高考数学题，对三角的考查方向有所改变，已逐步减弱了对复杂三角变换和特殊技巧的考查，重点转移到对三角函数的图像和性质的考查，以及对基础知识和基本技能的考查．三角函数的图像和性质中．对称性是重中之重．     

法制观的核心：正确的权利义务观

一、法制观与权利义务观。对大学生进行法制教育的目的是增强其法制观念，使其以正确的观念指导行为。法制观念是人们对法律现象的观点和态度的总称，具体表现为人们对法律的了解、掌握和运用的程度，对法律的要求和对行为是否合法的评价水平，以及遵守法律的自觉性。正确的法制观不仅表现为对现实法律的了解和掌握，更重要的在于对法律精神和实质的理解和认同，对法律的优劣依据现实做出恰当的评价，还在于将这种认识落实到自己的行为中。     

注重观念的成长

你要记住下面这首小诗： 从监狱的栏栅， 两人远望， 一人看见死亡， 在对完美人生的追求中，一切都取决于这种参照体系，这种约定俗成的观点，这种对自己、对他人、对人生、对世界的基本观念。我们看到的就是我们得到的。     

光辉的事业 崇高的师德

光阴似箭，转眼间在教师这条工作战线上我已快度过五个春秋。回首这一千多个日日夜夜，酸甜苦辣各显其问，也让我对教师这一职业有了更为深刻的认识。“师者，所以传道、授业、解惑也。”师者为师亦为范，学高为师，德高为范。走上三尺讲台，教书育人；走下三尺讲台，为人师表。教师不仅是社会主义精神文明的建设者和传播者，更是莘莘学子们的道德基因的转接者。因此，师德，不是简单的说教，而是一种精神体现，一种深厚的知识内涵和文化品位的体现!师德需要培养，需要教育，教师的品德和素养是教师提高，教育事业发展的一个重要前提，只有对“怎样做一名好教师”这一问题有深刻的认识，才能对自己提出更高的要求。“十年树木，百年树人”，踏上三尺讲台，也就意味着踏上了艰巨而漫长的育人之旅。师德古来有之，不同时代对师德有不同的要求，现代师德是对古代师德的继承与发展，知识经济时代对师德赋予了新的内涵。现代师德的含义是什么，怎样才能做好一名教师呢？裴认为以下几点非常重要：

随着老百姓对优质教育资源的需求日益增加，社会对教育的健康发展要求日益强烈，对应试教育的批评越来越强烈。笔者认为，应下大力气改造薄弱学校，大力发展素质教育，加强师资队伍建设等方面入手，科学有序地推进我国基础教育的健康发展，满足社会对教育公平的要求。     

父亲的贫穷与母亲的富有

父亲一生对钱守得很紧，恨不得把一分钱掰成两瓣用，可一辈子下来，父亲没余下多少钱，反而把自己的身体累垮了，中年便躺在病榻上。母亲一生对钱看得很淡，时常穷大方。母亲常说，钱财是身外之物，生不带来，死不带去。相反，她的生活常不缺钱用。     

师生共读的日子

对一线教师而言，读书是最好的备课，最好的休闲，最佳的修炼。 对小学生而言，读书可以丰富知识，开阔视野，活跃思维，陶冶情操，可以体验我“读书，我快乐”的心境。

对称的学问

对课本例题、习题的加工、改编，发挥课本例题、习题的功能，是近年来中考命题的发展趋势之一。这对减轻学生过重课业负担，避免题海战术，促进师生钻研教材，加深对教材的理解，综合运用所学知识，促进学生的思维能力的发展是大有裨益的。下面，就人教版教材几何第二册89页例3谈谈自己的个人拙见，供大家参考。

漏洞百出的教育

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help?     

只要努力,不要后悔

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love.

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages.

Sister Carrie, an Adherent of Desires

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.

The Reader Response Approach to Teaching of English Literature

During interview with English majors, it was found that a majority of students expressed disappointment with their experience of English literature classes. Students' dislike of learning English literature appears to be the major problem of teaching English literature in China. Reader response approach is a good way to solve this problem. In this paper, I explain the rationale behind the reader response approach, such as its origin, definition, features, assumptions, and strategies. Then I illustrate how reader response approach works as a teaching strategy by presenting several teaching models. At last I evaluate its usefuiness for teachers and present the advantages of reader response approach in Chinese context.
