University students come from different parts of the country with various purposes. However, a closer look at their reasons for studying at the university will enable us to (1)(classify) them roughly into three groups: those who have a(n) (2)(passion) for learning, those who wish to (3)(attain) a bright future, and those who learn with no definite purpose.

Firstly, there are many students who learn simply because they (4)(pursue) their goal of learning. Some read a wealth of British and American novels because they are keenly interested in literature. Others sit in front of the computer screen, working on a new program, (5)(virtually) day and night, because they find some computer programs (6)(fascinating), and they dream of becoming a "Bill Gates" one day.

Secondly, there are students who work hard mainly for a better and more (7)(prosperous) future. It seems that the majority of students fall into this group. After admission to the university, they read books after books to (8)(acquire) knowledge from all of the resources which are (9)(available) to them, and finally, to succeed in the future job market.

Thirdly, there are still some students who learn without a clear goal. They take courses, finish homework, enjoy life on campus, but don't want to (10)(sample) anything new or challenging. They have no idea what they will be doing after college. And they may end up with nothing in their lives.

Translation

Confucius was a great thinker and educator in Chinese history. He was the founder of Confucianism and was respectfully referred to as an ancient "sage". His words and life story were recorded in The Analects. An enduring classic of ancient Chinese culture, The Analects has had a great influence on the thinkers, writers, and statesmen that came after Confucius. Without studying this book, one could hardly truly understand the thousands-of-years' traditional Chinese culture. Much of Confucius' thought, especially his thought on education, has had a profound influence on Chinese society. In the 21st century, Confucian thought not only retains the attention of the Chinese, but it also wins an increasing attention from the international community.

Parents and teenagers have different or even opposite things to worry about. For example, while

a mother might have a hard time understanding why her teenagers' room is always a(n)

(1)(embarrassment) of dirty stuff, the teenagers are more worried about their next exams and may think it is (2)(ridiculous) for their mother to insist on keeping a clean room. It is therefore

important for you to (3)(appreciate) the differences and learn to communicate with your teenagers properly. (4)(Otherwise), your teenagers may say nothing and shut you out of their personal lives. Their refusal to talk with you may even create (5)(emotional) stress in your life.Learning effective ways to communicate can (6)(reverse) the situation of a difficult relationship, (7)(reduce) the stress of your life, and lead to a friendly relationship with your teenagers. First, you should learn to discuss serious problems in daily conversations. So, important topics, such as driving a vehicle and building a(n) (8)(romantic) relationship, could be dealt with through daily conversations.Second, learn to be an active listener. Many parents are so (9)(overwhelmed) with their work that they could hardly take some time for their (10)(beloved) children. Spend your time listening carefully to what your children like to talk about, and make sure your children feel they are being taken seriously. This will increase the chances of good communication.

According to the Chinese lunar calendar, August 15 of every year is a traditional Chinese festival — the Mid-Autumn Festival. This day is the middle of autumn, so it is called Mid-Autumn. One of the important Mid-Autumn Festival activities is to enjoy the moon.

People living far away from home will express their feelings of missing their hometowns and families at this festival. There are many customs to celebrate the festival, all expressing people's love and hope for a happy life. Since 2008, the Mid-Autumn Festival has become an official national holiday in China.

There have been increased demands for higher education to provide students with better courses and more opportunities. To deal with this (1)(complex) issue, colleges and universities are turning to the Internet for quick (2)(access) to its rich educational resources. Now the Internet has been accepted as the (3)(preferred) technology to many other methods in colleges and universities. Many teachers now routinely (4)(post) their teaching materials online. A growing number of schools offer at least some (5)(undergraduate) courses over the Internet. There are two different models of making use of the Internet for higher education. The first model (6)(seeks) to improve existing courses by using the Internet. This model provides high-speed Internet (7)(connectivity) to all students, faculty, and staff. While this model uses the Internet, it doesn't (8)(require) many changes, and it keeps most existing institutional structures unchanged.

China's space industry was launched in 1956. Over the past decades, China's space industry has created one miracle after another. In 1970 China launched its first man-made earth satellite, ranking China the fifth country in the world to independently develop and launch man-made earth satellites. In 1992 China began to carry out the manned spaceflight program. In 2003 China launched Shenzhou-5, a manned spaceship. The successful launch made China the third country to launch manned spaceships. In 2007 Chang'e-1, the first lunar-orbiting man-made satellite, was sent to space. In 2013 Shenzhou-10, the fifth manned spaceship, was launched successfully, laying the foundation for building the Chinese Space Station.

In January 2011, Daniel Hernandez saved congresswoman Gabrielle Giffords' life in a mass shooting in Tucson. He kept her alive by (1) (applying) pressure to her wounds and speaking (2) (tender) words of sympathy until medical people arrived. He was (3) (hailed) as a hero by the public. Although his devotion to public service is (4) (remarkable), in his book They Call Me a Hero: A Memoir of My Youth, Hernandez insists that he is not a hero.

Hernandez said that he initially resisted the idea of writing a book about his experience on that day of enormous (5) (tragedy). "I had been (6) (pushed) by a few publishers after the incident," he said. "I thought heroes should be people who make a lifetime (7) (commitment) to helping others."

However, Hernandez, now a school board member, had come to realize that he would be interested in writing a book (8) (focusing) on his public service."As a young official, I've faced some big challenges, and I want young people to know that they need to face challenges and (9) (involve) themselves in their communities."

When asked if he had any plan with a second book, Hernandez said his major purpose at present was to continue to serve his community and pursue his passion as a(n) (10) (advocate) for education. "But I'm not going to say no," he said.

Cricket might have started in early 16th-century England. Written records (5)(present) evidence of a game known as creag being played by Prince Edward at Newenden, Kent in 1301; and it is possible, (6)(despite) no hard evidence, that this was a form of cricket. By the end of the 18th century, cricket had (7)(developed) into a national sport of England. The growth of the British Empire led to cricket being played abroad and by the mid-19th century the first international (8)(contests) were held. Cricket has had a(n) (9)(remarkable) impact on popular culture in England. It has had an influence on the vocabulary of the English language, with such phrases as that's not cricket (10)(coined) to describe unfair behavior in general.

Nowadays college education cost is rising sharply. More and more college students have to work in order to (1)(generate) income to support themselves. But how can you prevent working from (2)(interfering)with your study?

Firstly, plan your class and work (3)(schedules) as far ahead as possible. Arrange your classes in a way so that you have one or two days for work.

Secondly, use time well instead of (4)(burning) the midnight oil. Studying late until midnight may make you tired and take a(n) (5)(consistent) toll on your health. Use those 10 minutes waiting for the bus to read a few more pages. If your job has a lot of downtime (自由支配时间), use the (6)(opportunity) to do school assignments. Never try to cut corners by copying assignments from other students.

Thirdly, set a goal for your academic performance. You'll probably have to (7)(decrease) your work hours, or even, if possible and necessary, (8)(withdraw) from the workforce to be successful in study. After all, it is not a good idea to risk (9)(compromising) your student career with part-time jobs.

The development of education has made significant contributions to China's economic development and social progress. In recent years, to satisfy the needs of social and economic development, the Chinese government has sped up the training of qualified personnel urgently needed in various fields.

Plagiarizing, copying a peer's test answers, and buying essays online are all ways in which college students cheat. According to a survey, nearly 80% of the students interviewed (1)(admitted) cheating at some point during their educational (2)(career). The consequences are severe (严重的), ranging from a failing grade to being (3)(expelled) from college. But why do students cheat? In college, the (4)(pressure) to do well is very high. Students know that without (5)(satisfactory) grades, their potential for success at school would be limited, so they sometimes copy their peers' answers in the exam. Besides, with today's technology, there is more information (6)(available) online than ever before. Students don't have to (7)(browse) the Internet long to find essays for sale. These are just some of the reasons why college students might cheat. Although colleges do everything they can to (8)(prevent) cheating, it still goes on. And cheating becomes more (9)(extensive) in some schools. But students should think about the consequences they will (10)(confront). They should stop and think about how happy and proud they will be when they earn a good grade in an honest way.

Integrity and harmony are traditional Chinese virtues. "Harmony" is demonstrated in various aspects. In regard to interpersonal relations, traditional Chinese thoughts hold that "Harmony is most precious" and "A family that lives in harmony will prosper". A harmonious social

environment can be created based on these principles. As for relations between human beings and nature, people should learn to understand, respect and protect nature. Harmony is essential to interpersonal relations, relations between human beings and society, as well as between human beings and nature. Nowadays, harmonious development is still the way of running the country and managing talented personnel. With the development of China's society, economy and culture, the idea of "harmony" goes even deeper into people's hearts. China is on its way toward the goal of building a harmonious socialist society.

数学专业英语一次函数专题

“数学专业英语一次函数专题”教学设计 1. 教学内容及解析 教学内容：与直角坐标系及一次函数相关的英语文献资料 内容解析：本节内容应从两个方面去考虑. 一方面，从数学知识的角度，本节所涉及的是从平面直角坐标系到一次函数的数学知识，都是学生学过的基础知识及其应用，是对于这些知识的拉练式复习，并作为后面用英语叙述解答相关问题知识基础；另一方面，从语言的角度，学生会接触到大量没有接触过，但他们却很熟悉的英语词汇及短语，主动学习的学生可以在老师的指导下快速理解其含义并加入到自己的知识体系中，但需要花时间巩固，是需要读、写、说来巩固的内容. 这也正是本节的重点和难点所在. 2. 教学目标及解析 教学目标：①能根据已有的数学知识和给出的单词对照表，将给出的相关数学定理及结论的英语版本翻译为中文；②能理解并解答用英语表述的相关数学问题；③能将解决数学问题的过程用英语进行书面表述；④初步了解用英语表达与直角坐标系及一次函数相关数学理论的范式. 目标解析：学生掌握基本词汇，并能阅读与本节内容相关的英语文献，是学习和使用数学专业英语的最基本要求，学生需要在学习的过程中逐渐由接受，即阅读或聆听，逐渐向输出，即书面和口头表达的方向发展. 为达到此目标，学生需要在课前独立完成对于本节需要的单词的学习，并阅读一系列简短的相关数学文献，并在这个过程中初步体会数学专业英语的表达范式；在课堂上，在教师的指导下对自己的认知进一步补充，并进行一定量的练习，暴露自己的问题，在教师的帮助下修正问题，完善认知. 3. 教学问题诊断分析 学生在进行语言表达时，往往受到母语的限制，对于非母语的表达方式的接受能力一时难以习惯，而数学对于表达能力则有更高的要求，要求叙述简洁、逻辑清晰，因此本教学设计强调学生在有相当阅读量的积累后，通过自主练习，逐渐感受用英语表达数学理论的基本范式. 教师在教学过程中的主要任务在于为学生提供合适的学习资料，在学生学习的过程中给予提示与指导，及时指出学生的问题并予以纠正. 对于语言的学习，阅读量的积累是至关重要的，教师在课堂上的讲解、学生在课堂上的练习，都只是学习的一部分环节，如果需要帮助学生正确掌握表达数学理论的范式，尽量不留死角，就必须保证课前预习和课后复习的有效性，预习复习材料的充足性，这对教师的教学资料的积累和学生自主学习能力，都是一个挑战. 4. 教学支持条件分析 学情条件：初二8班是实验班，学生有较强的学习热情和好奇心，也知道课前预习、课上参与学习活动、课后复习的重要性，在曾经的数学课程教学中，也有一定的课前预习，课堂讨论的传统，对于本教学设计的各个环节，是可以理解教师的用意，并遵循教师的指导进行学习活动. 在知识层面上，学生已经系统学习过一次函数相关的知识，课程中提供的学习资料都是学生熟悉的数学知识；学生在英语学习上，已经有多年的积累，对于英语语法的学

The constant of proportionality is the resistance value of the resistor in ohms. 流过电路里电阻的电流，与加在电阻两端的电压成正比，与电阻的阻值成反比。这就是欧姆定律。 （2）Many materials, however, closely approximate an ideal linear resistor over a desired operating region. 不过，许多材料在规定的工作范围内非常接近理想线性电阻。 （3）It should be noted that an ideal voltage source (dependent or independent ) will produce any current required to ensure that the terminal voltage is as stated, whereas an ideal current source will produce the necessary voltage to ensure the stated current flow. 应该注意：一个理想电压源（独立或受控）可向电路提供任意电流以保证其端电压为规定值，而电流源可向电路提供任意电压以保证其规定电流。 （4）A different class of relationship occurs because of the restriction that some specific type of network element places on the variables. Still another class of relationship is one between several variable of the same type which occurs as the result of the network configuration, i. e., the manner in which the various element of the network are interconnected. 一种不同类型的关系是由于网络元件的某种特定类型的连接对变量的约束。另一类关系由于网络结构，即网络的不同元件互相连接的方式所产生的相同形式的一些变量间的关系。 （5）The thermal conductivity of metals is as much as several hundred times that of glass. 金属的导热率比玻璃高几百倍。 （6）Magnetic line of force will，whenever passible, travel through iron or other magnetic materials. 磁力线只要有可能就会通过铁或其它磁性材料。 （7）Actually, 0 o C is indeed the lower limit to temperatures capable of being attained. 事实上绝对零度确是所能达到的温度的最低限度。 2. Translate the following into English. （1）电路元件吸收或释放的功率为元件两端的电压与流过该元件电流的乘积。 The power absorbed or supplied by a circuit element is the product of the voltage across the element and the current through it. （2）理想独立电源是一个有源元件，它所提供的电压或电流不依赖于电路中其他变量。 An ideal independent source is an active element that provides a specified voltage or current that is completely independent of other circuit variables. （3）受控电源是一个有源元件，它所提供的电压或电流受电路中某部分电压或电流控制。 An ideal dependent (or controlled) source is an active element in which the source quantity is controlled by another voltage or current. （4）叠加定理为：线性电路中，任一电压或电流都是电路中各个独立电源单独作用时，在该处产生的电压或电流的叠加。 The superposition principle states that the voltage across (or current through) an element in a linear circuit is the algebraic sum of the voltages across (or current through) that element due to each independent source acting alone. （5）计算机可分为模拟计算机和数字计算机两种。Computers may be classfied as analog and digital．（6）新型晶体管的开关时间缩短了三分之二。The switching time of the new-type transistor is shortened three times． （7）超导体在电气应用上的重要性不能被估计过高。The importance of superconductor in the uses of electricity cannot be overestimated.
