第一篇：数学专业英语作文(学习体会)

About learning the Mathematics English We major in Information and computing science , which belongs to Department of Mathematics.And also we need to learn Mathematics English in this term.As a smoothly through this term student , I benefited a lot.Firstly , I think learning English needs a lot of practice.We need to practice listening , writing , reading and thinking in English.But for the Mathematics English , it’s difficult.Because there are many different.Mathematics English always describe objective facts and truth.There are many long sentence and professional words and phrases , which is different to our Oral English.So learning Mathematics English is a challenge.Unfortunately , I don’t learn it well.Although English is the common language of communications for world diplomacy, economics and defence, then let us be as fluent and proficient in it as possible, for the sake of our own country's advancement and prestige.May be we will repent learning poorly in Mathematics English when we write graduation thesis for searching the English thesis.Secondly , I learn a little about Mathematics English.We study some texts about Mathematics, Equation ,Geometry ,Set , Function , Sequences and Their Limits , The Derivative of a

Function , Elementary Mathematical Logic and so on.Also I learn some useful things , for example , some professional words and phrases , and how to describe some sample objective facts and truth , how to describe some sample formula in English.May be it helpless in my graduation thesis , but it will keeps in my mind for many years!

Thirdly , the teacher’s teaching methods is very well.He gave us a stage and let us play fully!We can learn together and there full of cordial and friendly atmosphere where we can make common progress and common development.Some students seized the opportunity but some let the chance slip away.I caught the opportunity and did my best!Thank for teacher giving the stage let me play my role!To sum up, my college life and learning life still exist many shortcomings.I will be in the next few months of this struggle, make oneself to make greater progress.

专业英语学习体会

英语作为一门重要的学科，正在由于科技的飞速发展、信息全球化、社会化的日趋接近以及国际语言的特殊身份而身价倍增，成为了跨入二十一世纪所必备的三张通行证之一。新的一代是否具备这张通行证将会直接影响祖国明天的辉煌。从这个意义上说，通过学习英语来培养学生积极学习、主动探取的主体性品质以适应现代化社会的发展显得尤为必要。尤其是我们当代研究生，掌握好英语，尤其是自己专业方面的外语，无论是对自己完成学业，还是未来找工作都有很重要的作用。通过这学期专业英语的学习，我学到了很多东西，更重要的是知道了学习专业英语的重要性。

首先，虽然我们以前已经学了很长时间的英语，但学的还远远不够。因为我们学的英语基本上都是一些基础的、常用的表达，对于自己专业领域的一些词汇怎么表达还不了解。所以，学习专业英语是很必要的。尤其是随着地理学科的不断发展和新技术的广泛应用，对地理专业学生来说学习地理专业英语是必不可少的，也是吸取国外先进知识，进行国内外学术交流的基础。因为英语作为世界上应用最广泛的一门语言，许多专业领域的文献和资料都是用英文书写的。如果我们想了解我们专业领域的最新研究成果，我们就必须学好专业英语，这样才能读懂自己专业方面的英文文献，使自己的研究跟上时代的步伐。

其次，随着中国国门的不断开放，我们与国外相关专家学者交流的机会将不断增多，这就需要我们掌握好英语——这张世界的通行

证。如果我们不能很好的掌握自己研究领域的英文表达，那么在与国外专家交流时就会遇到这样那样问题，影响我们的正常交流。而一口流利的，专业词汇把握准确的英语，则会给对方留下深刻的印象，从而加深交流，真正达到交流的目的。可想而知，两者的差距。

最后，专业英语是高等学校研究生阶段各专业的一门重要辅助课程，是基础英语的延伸，其目的是为了拓宽学生的专业词汇量和阅读量，特别是强化英文表达方法，为将来的学术论文的阅读、写作和交流打下坚实的基础。地理专业是个古老的学科，为了追踪该学科的动态并赶上国际水平，必须熟练的掌握该专业的英语词汇量及表达方式；地理专业学生毕业后在很大程度上面临的是教学和科研，必须了解国内外地理理领域的最新动态，并需要经常查阅文献、写科研论文、参加学术会议等；此外，毕业生就业实行双向选择，自主择业，人才市场对于复合型人才的需要越来越多。因此，地理专业英语课程的开设就显得尤为重要。

1.AIR POLLUTION--THE MOST URGENT ENVIRONMENT PROBLEM

Environmental problem is the impacts of human activities on the environment,resulting in environmental quality changing, and the impacts of such changes on human life, health, and production activities.In my opinion, air pollution is the biggest environmental problem.With the rapid development of economy and the excessive using of oil and coal, the air condition is disturbed.Air pollution results in two aspects.On the one hand,human health is seriously threatened.From the period of industrial civilization in the 20th Century, a series of environmental pollution incidents have been produced, which have taken thousands of people's health and even life.On the other hand,human activities have been emissioning a large amount of greenhouse gases, including carbon dioxide, methane, nitrogen oxide and so on, which have been causing a series of global problems,such as extreme climate occured frequently ,the ecological enviroment deterioratedand global political issues.In generally, air pollution becomes worse and worse, which are threatening the human survival and development,In order to protect the environment, the government must take even more effective measures.First, the government should render people fully realize the importance of environmental protection through education.Second, the government should encourage the people to use the environment frienfly product.Finally, those who destroy the environment intentionally should be severely punished.We should let them know that destroying environment means destroying mankind themselves.

Some basic principles of combinatorial analysis

Many problems in probability theory and in other branches of mathematics can be reduced to problems on counting the number of elements in a finite set.Systematic methods for studying such problems form part of a mathematical discipline known ascombinatorial analysis.In this section we digress briefly to discuss some basic ideas in combinatorial analysis that are useful in analyzing some of the more complicated problems of probability theory.If all the elements of a finite set are displayed before us, there is usually no difficulty in counting their total number.More often than not, however, a set is described in a way that makes it impossible or undesirable to display all its elements.For example, we might ask for the total number of distinct bridge hands that can be dealt.Each player is dealt 13 cards from a 52-card deck.The number of possible distinct hands is the same as the number of different subsets of 13 elements that can be formed from a set of 52 elements.Since this number exceeds 635 billion, a direct enumeration of all the possibilities is clearly not the best way to attack this problem;however, it can readily be solved by combinatorial analysis.This problem is a special case of the more general problem of counting the number of distinct subsets of k elements that may be formed from a set of n elements(When we say that a set has n elements,we mean that it has n distinct elements.Such a set is sometimes called an n-element set.),where nk.Let us denote this number by f(n,k).It has long been known that

n(12.1)f(n,k)k, 

nwhere, as usual k denotes the binomial coefficient, 

nn!kk!(nk)!

52In the problem of bridge hands we have f(52,13)13635,013,559,600 

different hands that a player can be dealt.There are many methods known for proving(12.1).A straightforward approach is to form each subset of k elements by choosing the elements one at a time.There are n possibilities for the first choice, n1 possibilities for the second choice, and n(k1)possibilities for the kth choice.If we make all possible choices in this1

manner we obtain a total of

n(n1)(nk1)n!(nk)!

subsets of k elements.Of course, these subsets are not all distinct.For example, ifk3the six subsets

a,b,c,b,c,a,c,a,b,a,c,b,c,b,a,b,a,c

arc all equal.In general, this method of enumeration counts each k-element subset exactly k!times.Therefore we must pide the number n!/(nk)!by k!to

nobtain f(n,k).This gives us f(n,k)k, as asserted.

组合分析的一些基本原则

许多概率论和其他一些数学分支上的问题，都可以简化成基于计算有限集合中元素数量的问题。研究这些问题的系统方法，是一个数学学科--组合分析的一部分。在本节，我们将离题简要地讨论一些组合分析的基本概念，它对于分析概率论中一些更复杂的问题是十分有用的。

如果一个有限集合的所有元素都展示在我们面前，通常不会难以计算其元素的总数。然而，更多的往往是一些不能够描述或者不能够展示其所有元素的集合。例如，我们会问打桥牌时手牌的有多少种不同的组合。每个玩家处理从52张牌中发的13张牌。可能的不同手牌组合数相当于从含有52个元素的集合在中选出13个元素组成不同的子集的子集的个数。因为这个数字超过了635亿，直接枚举所有的可能性显然不是解决这个问题的最好方式。然而，它可以很容易地用组合分析来解决。

这个问题是一个更普遍的问题的一种特殊情况，一个含有n个元素的集合有多少个含有k个元素的子集，这里n大于等于k。我们用f(n,k)来表示,众所周知

n(12.1)f(n,k)k, 

n这里，k像通常一样表示一个二项式 

nn!kk!(nk)!

在这个问题里面，每个玩家的可能手牌有f(52,13)52635,013,559,60013

种不同的情况。

有许多已知的方法可以证明(12.1)。一种直接的方法是，每次从原来的集合中取一个元素，共取k次构成一个含有k个元素的集合。第一次选择元素有n种可能，第二次有n1种可能，依次类推，第k次有n(k1)种可能。如果我们用这种方式做出所有可能的选择，那么一共有

n(n1)(nk1)n!(nk)!

个k元素子集。当然，这些子集并不是都不相同。举个例子，如果k3，这6个子集 a,b,c,b,c,a,c,a,b,a,c,b,c,b,a,b,a,c

是相同的。在一般情况下，这种统计方式把每个k元素子集统计了k!次。因此，我们必须把n!/(nk)!除以k!来得到f(n,k)。以上确切的告诉我们

nf(n,k)k 

《小学数学课程标准理念与目标》学习体会

这次培训学习，通过观看视频，最令我感受最深的是南开大学著名数学教授顾沛老师讲的《小学数学课程标准理念与目标》，让我受益匪浅，让我对小学数学课程标准理念与目标，有了更深刻的了解，也有更新的感受：下面我简单谈谈本次培训学习的体会与收获。

一、新课程目标鲜明了以下几点：

1、获得适应社会生活和进一步发展所必需的数学的基础知识、基本技能、基本思想、基本活动经验。

2、体会数学知识之间、数学与其他学科之间、数学与生活之间的联系，运用数学的思维方式进行思考，增强发现和提出问题的能力、分析和解决问题的能力。

3、了解数学的价值，提高学习数学的兴趣，增强学好数学的信心，养成良好的学习习惯，具有初步的创新意识和实事求是的科学态度。

二、新的课程标准的变化。

1、新的课程标准完全改变了以往课标“知识——能力——情感”的梯级认知目标体系，而是以情感、态度、价值观目标为首，兼顾能力目标、知识目标。更加关注学生学习的过程和方法，尤其是伴随这一过程而产生的积极情感体验和正确的价值观。因此教师在使用新课程标准的过程中，主要也应关注，如何利用各门学科所特有的优势促进每一个学生的健康发展，而不是仅仅关心学生对某个结论是否记住，记得是否准确?不是仅仅关心学生对某项技能是否形成，并且运用起来是否得心应手?

2、新版课程标准指出：学生是学习和发展的主体，数学课程必须根据学生身心发展和数学学习的特点。教师课堂上的所有教学都应坚持以生为本，全面提高学生的数学素养。

3、孩子是学习的主人，教学时还应顺应孩子的天性，爱护儿童的好奇心、求知欲，鼓励孩子自主阅读、自由表达；尊重孩子的创造，充分激发他们的问题意识和进取精神。同时要关注孩子的个体差异和不同的学习需求。教师对于教学方法的选择，评价方式的设计，都应坚持以生为本。

三、教学反思。

反思自己的课堂，我认识到自己的生本意识还有待加强，有时对于教学的预设过多，导致对学生的牵引教多。今后的教学中我将更加关注学生，把时间充分的交给孩子们自己去读、去学习、去感悟，这样的教学，才是学生真正需要的，才是真正有实效的。

通过学习，我发现要将课标的方方面面落到实处，我们教师除了更新观念，切切实实抓好教学，更重要的是教师要时时加强学习，理念与实践齐头并进，必须建立和实践终身学习思想，才能实现自我完善与自我发展。

四、努力方向。

在以后的教学中，我会时时反思我的课堂，不断提升、充实自己，将课标中的理念运用到自己的课堂之上，使自己的教学更有实效。
