Good Sportsmanship Is of Vital Importance
Sportsmanship is a great tradition in sports and competitions that means playing clean and handling both victory and defeat with grace, style, and dignity. Today, quite a few athletes lack sportsmanship. I personally hold that good sportsmanship is of vital importance for both the athletes themselves and their offspring.
Firstly, practicing good sportsmanship wins respect. When you win, the trick is to be a gracious and generous winner. Good sportsmanship means acknowledging victories without humiliating opponents, being quietly proud of success, and letting victories speak for themselves. Even if you win by a landslide, good sportsmanship means still finding ways to compliment your opponents. By demonstrating your respect to your opponents, you win respect from them too. Secondly, good sportsmanship teaches children how they should behave. Kids learn the basics of sportsmanship from the *s in their lives, especially their parents and their coaches. Kids who see *s behavin in a sportsmanlike way gradually come to understand that the real winners in sports are those who know how to persevere and to behave with dignity-whether they win or lose a game. A child who practices good sportsmanship is likely to carry the respect and appreciation of other people into every other aspect of life.
In conclusion, sportsmanship is a manifestation of our own ethics in real life. For the sake of sportsmen themselves and the generation to come, good sportsmanship should be highly advocated. (235 words)
The last several decades have seen a decline in parental influence on their children. In fact, it seems that the more children watch movies and television and get influenced by people outside the home, the more their parents lose control over them. Nowadays, children and teens are often searching for role models other than their parents to imitate. They naturally look to celebrities like singers, movie stars, and athletes to be their guides. For example, many high school students like to dress in the latest fashions that have been made popular by various celebrities. They even cut their hair like famous people or say the same things as them. Parents sim* cannot complete with these stars when it comes to influencing their children. Many television shows, movies, and video games have high levels of violent content and bad language, which greatly influence young people watching them. Children have begun acting badly based upon what they have seen on various media.

——论文写作的基本要求
论文写作的基本要求
导语：对于刚接触的毕业生来说，是非常困难的，论文写作的还有内容的一些规范都是需要掌握的，那么毕业论文写作要求有哪些呢？下面和小编一起来看论文写作的基本要求，希望有所帮助！
一、基本要求
1、独立性：毕业论文必须经护生本人努力、指导老师指导下独立完成，不得弄虚作假，抄袭或下载他人成果。
2、专业性：毕业论文的选题必须在护理学专业范围之内，并具有护理专业特点。
3、鲜明性：论文应主题鲜明，论题、论点、论据一致，中心突出，论据充分，结论正确；结构紧凑，层次分明，格式规范，文字流畅，切忌错别字。
4、标准化：论文中使用的度量单位一律采用国际标准单位。
5、三线表：论文中图表具有代表性，对所使用的图表要给予解释，统一标注编号和图题，放置在论文的适当位置中，图表要清晰、简洁、比例适当。
6、篇幅字数：篇幅在4000字左右（不含图表、等），不少于3500字。
7、字形大小：为小二号宋体，标题为四号宋体加粗，正文用宋体小4号字，1.5倍行间距，A4纸打印，页边距：上、下各2.54cm，左、右各3.17cm，左侧装订，一式三份。护生同时应将毕业论文制作成Word电子文档（含初稿和正稿）上交学院。
8、完整性：论文形式应完整，按照以下顺序装订毕业论文。
（1）论文封面（首页）。
（2）论文目录（次页）。
（3）报告。

——大学英语写作常见的九种错误语法 (菁华3篇)
句子结构混乱主要是受汉语思维方式影响而导致的。同学们在日常学*中应多加练*，培养语感。
例1：There are many students are playing basketball on the playground.操场上有许多学生在打篮球。
解析：上面的句子中出现了两个谓语动词，不符合英语的语法*惯。
改为：Many students are playing basketball on the playground.
例2：The girl is standing over there is from a big city.站在那边的女孩来自一个大城市。
解析：一个简单句中不能有两个谓语系动词，结构混乱。
改为：The girl standing over there is from a big city.
英语的谓语动词在人称和数上必须与主语保持一致。由于受汉语的影响，许多同学在写作时经常忽略句子的'主谓一致关系，从而造成错误。
例：Once one have money，he can do what he want to do.人一旦有了钱，他就能想干什么就干什么。
解析：one是单数第三人称，因而本句的have应改为has;同理，want应改为wants，本句是典型的主谓不一致。
改为：Once one has money,he can do what he wants to do.
句子不连贯是指一个句子内部前言不搭后语，或是结构上不畅通。句子不连贯也是英语书面表达中比较常见的毛病。
例：The fresh water，it is the most important things of the earth.淡水是地球上最重要的东西。
解析：The fresh water与逗号后的it不连贯，It与things在语法上不一致。
改为：Fresh water is the most important thing in the world.
——学位英语写作 (菁华3篇)
Self-confidence is very important to our life. As a wise man once said, "If you have no confi-dence in yourself, you are twice defeated in the race of life. With confidence, you have won even before you have started. "
If you are full of self-confidence, your creativeness, your enthusiasm will all be aroused, and you will overcome difficulties. As a result, your dreams will come true. On the contrary, if you have no confidence in yourself, there is little possibility that you would ever achieve anything.
Failure will be following you. But self-confidence comes only when you know yourself. You should know both your weaknesses.
Nowadays, most people want to enter graduate school. In fact, this desire has grown considerably in the past few years. Students struggle to pass the graduate school entrance exam, to survive the pro-gram, and find a job at the end of it. They read many exam preparation books. They may also attend special "exam preparation" seminars and courses. There are some reasons for such phenomenon.
First is the general perception that a graduate school diploma, a master's degree, is needed for getting a better job. Second is that some students might not be sure what they want to do, and a few more years inside the courtyards of academic seems desirable.
In my opinion, this is not reasonable. I don't deny that a few passed and went on, but the majority failed and finally wiped away their valuable times. So we don't have
Writing
Directions: For this part, you are allowed 30 minutes to write a composition on the topic "Is a Test of Spoken English Necessary". You should write at least 120 words, and base your composition on the outline given in Chinese below:
1.很多人认为有必要举行口语考试，理由是……；
2.也有人持不同的意见，……；
3.我的看法和打算。
范文
Is a Test of Spoken English Necessary
In many kinds of English tests such as CET (College English Test), TEM (Test for English majors), etc. a test of spoken English will be optional. Some people consider that it is unquestion-ably necessary to hold a test of spoken English in China because spoken English is as important as written English. Both of them are effective communication ways for English speakers. But some-times even those top students who are good at grammar and writing skills find that it is difficult to express their thoughts freely when speaking. A test of spoken English will make students attach more importance to oral English, and thus help them with their communicating skills.
On the other hand, there are also people who hold that good reading, writing and translating skills would be enough for the average English learners. College students are already under great pressure from their study. Another required test will be a burden to them.
In my opinion, I believe that a test of spoken English will do more good than harm. And I shall make all my efforts to practice and improve my spoken English.
——英语写作中常见的九种句法错误通用五篇
在口语中，交际双方可借助手势、语气等来理解对方的意思，不完整的句子也完全可以被理解。可是书面语就不同了，句子结构不完整会令意思表达不清，这常常发生在主句写完以后，学生又想加些补充说明的情况下。
例：There are many ways to know the society. For example, by TV, radio,newspaper and soon.了解社会的途径有很多，比如，可以通过电视、广播、报纸，等等。
解析：本段后半部分“For example，by TV，radio，newspaper and so on.”不是一个完整的`句子，仅为一些不连贯的词语，不能独立成句。
改为：There are many ways to know society,for example,by TV,radio,and newspaper.
同学们在写书面表达时应尽量做到简洁：写句子没有一个多余的词，写段落没有一个多余的句子;能用单词的就不用词组，能用词组的就不用从句或句子。
例1：In spite of the fact that he is lazy，I like him.尽管他很懒惰，我还是喜欢他。
解析：本句的“the fact that he is lazy”系同位语从句，我们应按照“简洁”的原则加以简化。
改为：In spite of his laziness,I like him.
例2： For the people who are diligent and kind, money is just the thing to be used to buy the thing they need.对于勤奋善良的人来说，钱只是用来购买所需东西的工具。
解析：整个句子可以大大简化，累赘重复过多。
改为：Diligent,caring people use money only to buy what they need.
句子结构混乱主要是受汉语思维方式影响而导致的。同学们在日常学*中应多加练*，培养语感。
例1：There are many students are playing basketball on the playground.操场上有许多学生在打篮球。
解析：上面的句子中出现了两个谓语动词，不符合英语的语法*惯。
改为：Many students are playing basketball on the playground.
例2：The girl is standing over there is from a big city.站在那边的女孩来自一个大城市。
解析：一个简单句中不能有两个谓语系动词，结构混乱。
改为：The girl standing over there is from a big city.
一、词性误用
词性误用常表现为：介词错用为动词，形容词错用为副词，名词错用为动词等。
例：They earn some money so that they can independence.他们挣钱是为了自立。
解析：independence是名词，句中误用为动词。
改为：They earn some money so that they can be independent.
二、修饰语错位
英语与汉语不同，同一个修饰语放在句子中不同的位置，可能会引起句子含义的变化。这一点常被同学们所忽视，因而造成了不必要的误解。
例：I believe I can do it well and I will better know the world outside the campus.我相信我会做得很好，而且我将对校园外的世界有更好的了解。
解析：better位置不当，应置于句末。
改为：I believe I can do it well and I will know the world outside the campus better.
三、句子不完整
在口语中，交际双方可借助手势、语气等来理解对方的意思，不完整的句子也完全可以被理解。可是书面语就不同了，句子结构不完整会令意思表达不清，这常常发生在主句写完以后，学生又想加些补充说明的情况下。
例：There are many ways to know the society. For example, by TV, radio,newspaper and so on.了解社会的途径有很多，比如，可以通过电视、广播、报纸，等等。
解析：本段后半部分“For example，by TV，radio，newspaper and so on.”不是一个完整的句子，仅为一些不连贯的词语，不能独立成句。
改为：There are many ways to know society,for example,by TV,radio,and newspaper.
四、主谓不一致
英语的谓语动词在人称和数上必须与主语保持一致。由于受汉语的影响，许多同学在写作时经常忽略句子的`主谓一致关系，从而造成错误。
例：Once one have time，he can do what he want to do.人一旦有了时间，他就能想干什么就干什么。
解析：one是单数第三人称，因而本句的have应改为has;同理，want应改为wants，本句是典型的主谓不一致。
改为：Once one has time, he can do what he wants to do.
五、指代不清
指代不清主要指代词与被指代的人或物关系不清，或者先后所用的代词不一致。
例1：Mary was friendly to my sister because she wanted her to be her bridesmaid.玛丽和我姐姐很要好，因为她要她做她的伴娘。
解析：读完上面这一句话，读者无法明确地判断两位姑娘中谁将结婚，谁将当伴娘。如果我们把容易引起误解的代词加以明确，意思就一目了然了。
改为：Mary was friendly to my sister because she wanted my sister to be her bridesmaid.
例2：And we can also know the society by serving it yourself.我们还可以通过亲身参与、体验的方式了解社会。
解析：句中人称代词we和反身代词yourself指代不一致。
改为：And we can also know the society by serving it ourselves.
六、累赘
同学们在写书面表达时应尽量做到简洁：写句子没有一个多余的词，写段落没有一个多余的句子。
例1：In spite of the fact that he is lazy，I like him.尽管他很懒惰，我还是喜欢他。
解析：本句的“the fact that he is lazy”系同位语从句，我们可按照“简洁”的原则加以简化。
改为：In spite of his laziness,I like him.
例2： For the people who are diligent and kind, money is just the thing to be used to buy the thing they need.对于勤奋善良的人来说，钱只是用来购买所需东西的工具。
解析：整个句子可以大大简化，累赘重复过多。
改为：Diligent,caring people use money only to buy what they need.
七、句子不连贯
句子不连贯是指一个句子内部前言不搭后语，或是结构上不畅通。句子不连贯也是英语书面表达中比较常见的问题。
例：The fresh water，it is the most important things of the earth.淡水是地球上最重要的东西。
解析：The fresh water与逗号后的it不连贯，it与things在语法上不一致。
改为：Fresh water is the most important thing in the world.
八、句子结构混乱
句子结构混乱主要是受汉语思维方式影响而导致的。同学们在日常学*中应多加练*，培养语感。
例1：There are many students are playing basketball on the playground.操场上有许多学生在打篮球。
解析：上面的句子中出现了两个谓语动词，不符合英语的语法*惯。
改为：Many students are playing basketball on the playground.
例2：The girl is standing over there is from a big city.站在那边的女孩来自一个大城市。
解析：一个简单句中不能有两个谓语系动词，结构混乱。
改为：The girl standing over there is from a big city.
九、句型单调，句子与句子之间缺乏过渡
一篇文章如果简单句过多，句型单调，即使语法错误较少，思路较清晰，看后也会使人感到乏味。同学们应学会单句、复句交替使用，经常变换句型，尝试使用一些较复杂的语法结构及句型，适当运用过渡词，使文章更加连贯。
例：They sleep fewer than eight hours every day. It has great influence on their health.
解析：这段话中使用的全部是简单句，句型比较单调，可以改为定语从句或加入插入语。
改为：Actually, they sleep fewer than eight hours every day, which will,no doubt, have great influence on their health.
英语的谓语动词在人称和数上必须与主语保持一致。由于受汉语的影响，许多同学在写作时经常忽略句子的主谓一致关系，从而造成错误。
例：Once one have money，he can do what he want to do.人一旦有了钱，他就能想干什么就干什么。
解析：one是单数第三人称，因而本句的have应改为has;同理，want应改为wants，本句是典型的主谓不一致。
改为：Once one has money,he can do what he wants to do.
