大学英语写作常用句型(推荐20篇)

Communicating in English effectively is essential in todays global economy.

在今日全球化的经济环境下，有效地用英语交流已经变得至关重要。

But conveying your ideas clearly is a skill that needs to be learnt. Too often people simply copy the style of their co-worker and especially their superiors as they think this "good English". You see examples in your in-box every day - emails that are difficult to understand and that you need to read over and over again to get the message.

然而如何清晰地表达你的想法却是门大学问。太多时候人们只是简单地照抄他们眼中同事，尤其是上级写出来的“漂亮英语”。你每天都能在收件箱里看到很多例子——那些难懂的需要你读好多遍才能理解的邮件。

A big mistake is to pad out your writing with unnecessary words and phrases. Remember that the purpose of your writing is to communicate your ideas clearly.

一个巨大的错误就是用一些不必要的单词和词组让你的文章变得冗长。你要牢记你写作的目的是为了更清晰地交流你的想法。

Always try to reduce the number of words in your sentences and avoid lengthy phrases that can be replaced with a shorter alternative. Here are some examples:

总是尽可能减少你句子中使用的字数，避免使用可以用更短的词代替的长词。以下是一些例子：

*Instead of "prior to" use *before*

用“before”代替“prior to”

*Instead of "subsequent" use *after*

用“after”代替“subsequent”

*Instead of "in order to" use *to*

用“to”代替“in order to”

*Instead of "in the event that" use *if*

用“if”代替“in the event that”

*Instead of "with reference to" use *about*

用“about”代替“with the reference to”

*Instead of "state of the art" use *latest*

用“latest”代替“state of the art”

*Instead of "due to the fact that" use *since*

用“since”代替“due to the fact that”

*Instead of "not later than 2pm" use *by 2pm*

用“by 2pm”代替“not later than 2pm”

*Instead of "at the present time" use *now*

用“now”代替“at the present time”

Remember about organisation as well. Use topic sentences to indicate what each paragraph is about. In addition, keep your emails short. No one likes to read an email 10 paragraphs long!

同时也要记得文章有组织性。第一句话就要开门见山地点出你每一段要讲什么。除此之外，要控制你邮件的长度。没人想读一条长达10段的邮件。

By using simple words and easily understood phrases you can improve the clarity of your message no end.

通过使用简单的单词和易懂的词组，你就能最终提高你信息的清晰度。

英语写作是一种创作性的学习过程。启动知识信息储存，构思立意，谋篇布局，遣词造句，对语言表达的正确性和准确性、思维的逻辑性和文章的条理性都比口语要求更高。通常英语写作有以下几个特点：紧扣教学大纲对考生书面表达的要求;以有指导的写作为主(guidedwriting)，便于考生在短时间内构思成文;突出试题的交际性，考查考生在特定的情景中运用语言的能力;增强试题的实用性，所选话题贴近学生学习生活，为学生所熟悉;看图作文主要考查考生运用所学知识解决实际问题的能力。

一、给写作留有充分的时间

在小升初英语题中， “书面表达”往往是最后一项，有的学生把最后几分钟用在写作上，匆匆了事，这是很不明智的。学生用在写作上的时间应不少于10分钟，力争不丢分，少丢分。

二、认真审题，先打草稿

写之前一定要认真阅读写作要求，切忌见题就写。小升初英语作文主要有两种类型： “提示作文”和 “看图作文”。 “提示作文”一般已经给出要点，而 “看图作文”则需根据图画及提示在很短的时间内将要点列出。把要点列出后，在草稿纸上写提纲，打草稿，就可以看出大概有多少字。在正式往试卷上写之前，根据题目要求适当增减内容，保持卷面整洁。

三、写好简单句，慎用长句

考生要根据所列要点，运用相应的提示词及正确的动词形式在稿纸上写出简单句。考生应熟悉简单句的五种基本句型，尽量使用简单句。在简单句的基础上，根据各句之间的关系适当加上一些连词，使得整篇文章结构紧凑，行文流畅。套用句型，能显示考生的英语基础扎实，提高作文档次。慎用长句是因为其成分多，结构复杂，所以出错的机会也多。考生在没有十足的把握时最好少用或不用长句，以免给自己的作文带来不必要的损失。

四、熟悉各种时态，灵活运用

时态是学习英语语言的难点。考生务必系统地学习初中出现的各种时态，做到灵活运用。在同一篇作文当中，时态要保持一致。

五、切忌中式英语，避免生搬硬套

一些学生因缺乏写作技巧，往往在写英语作文时，根据中文意思堆积英文单词，编造出许多中式英语，结果错误百出，意思表达不清楚，直接影响考试成绩。

六、认真检查和修改，减少错误

做完写作题后要从头至尾读一遍，检查一下文章是否通顺，有无逻辑错误，标点符号、单词拼写和时态运用是否正确，避免笔误。

考研英语应用文写作范文之感谢信感谢信

结构要点感谢信是就某事向收信人表示感谢的信件，分为三个部分：

1． 指出对方帮助自己的事情，表示感谢；

2． 展开叙述这件事；

3． 再次感谢，并可表示希望回报对方。

Suppose your were recommended by Professor Sun to get further education in Yale University last June and now you have been admitted by that university. Write a letter to Professor Sun to express your gratitude in about 100 words. Do not sign your own name, using “Li Ming” instead.Dear Professor Sun,

I am writing to extend my gratitude to you—without your help I would not have been a postgraduate student of Applied Mechanics Department of Yale University.

Last June, you helped me with no reservation when I applied for Yale University. You wrote a recommendation letter for me to Professor W, the dean of the department. You gave me instructions on how to fill the application forms and write the application letters. Whats more, you also taught me how to take care of myself and get along with others, which I believe are lifes great lessons.

Your help enabled me to fulfill my dream to pursue my studies in a great university. In the following days I will remember what you have told me and work and study hard to be a capable, conscientious and responsible person.

Yours truly,

Li Ming

感谢信

语言注意点感谢信应充分表达自己的谢意，切不可给对方草率的印象。可借助谈对方的帮助来进一步表达感激之情。言辞应真挚、得体。

Suppose you were taken good care of by Aunt Sun when you pursued your studies in Los Angels where Sun lived. Write a letter in about 100 words to extend your appreciation. Do not

sign your own name, using “Li Ming” instead.Dear Aunt Sun,

It is a great pleasure to extend my sincere gratitude to you for your hospitality and consideration while I pursue my bachelors degree at University of California.

As soon as I arrived in Los Angeles, you found me an apartment near my university. When I met with difficulties you often sent your daughter to help me and when I felt homesick you often talked to me patiently. You told me how to improve my efficiency in both work and study and how to get on well with teachers and schoolmates. Furthermore, you invited me to dinner on nearly every weekend.

Without your help, I would not have graduated with honors and found a satisfactory job back here in China. I know I can never repay you for everything you have done for me in the past four years, but you can be sure that I

Best regards.

Yours faithfully,

Li Ming ll never forget it.

南瓜灯(Jack-O-Lantern)是庆祝万圣节的标志物。下面语文迷网整理了关于南瓜灯的故事作文，希望对你有帮助。

One story about Jack， an Irishman， who was not allowed into Heaven because he was stingy with his money. So he was sent to hell. But down there he played tricks on the Devil (Satan)， so he was kicked out of Hell and made to walk the earth forever carrying a lantern.

Well， Irish children made Jacks lanterns on October 31st from a large potato or turnip， hollowed out with the sides having holes and lit by little candles inside. And Irish children would carry them as they went from house to house begging for food for the village Halloween festival that honored the Druid god Muck Olla. The Irish name for these lanterns was "Jack with the lantern" or "Jack of the lantern，" abbreviated as " Jack-o-lantern" and now spelled "jack-o-lantern."

The traditional Halloween you can read about in most books was just childrens fun night. Halloween celebrations would start in October in every elementary school.

关于万圣节有这样一个故事。是说有一个叫杰克的爱尔兰人，因为他对钱特别的吝啬，就不允许他进入天堂，而被打入地狱。但是在那里他老是捉弄魔鬼撒旦，所以被踢出地狱，罚他提着灯笼永远在人世里行走。

在十月三十一日爱尔兰的孩子们用土豆和萝卜制作“杰克的灯笼”，他们把中间挖掉、表面上打洞并在里边点上蜡烛。为村里庆祝督伊德神的万圣节，孩子们提着这种灯笼挨家挨户乞讨食物。这种灯笼的爱尔兰名字是“拿灯笼的杰克”或者“杰克的灯笼”，缩写为Jack-o-lantern 。

现在你在大多数书里读到的万圣节只是孩子们开心的夜晚。在小学校里，万圣节是每年十月份开始庆祝的。孩子们会制作万圣节的装饰品：各种各样桔红色的南瓜灯。

英语四级考试目的是推动大学英语教学大纲的贯彻执行，对大学生的英语能力进行客观、准确的测量，为提高我国大学英语课程的教学质量服务。下面是小编为大家带来的基础薄弱如何进行英语四级写作训练的知识，欢迎阅读。

英语四级写作备考可分为四大步骤：

一、 背诵：

首先认真研究历年四级写作真题，重点研究2001年6月—2005年12月的11次真题，分析近年来四级写作的出题规律和考试重点，从语言、结构、 内容三大层面，认真研读经典写作真题范文：语言方面学习范文中的精彩词汇、词组、句型；结构方面学习范文的框架结构、内在逻辑、关联词、同义替换和代词替换；内容方面学习范文的论点、论据和论证。同时背诵精彩写作范文，要求滚瓜烂熟、脱口而出、多多益善，扎扎实实提高自己的写作实力。历年英语四级六级真题 >>

二、默写：

背诵熟练之后默写下来，仔细对照原文，会发现你默写的文章与原文有一些语法、拼写、标点的区别，这些区别就是你的写作弱点，学习关键在于针锋突破，不要全面出击。这些弱点正是你在考试中扣分的原因所在，把这些弱点意义克服，分数自然就会提高。

三、 中译英：

首先将写作真题范文译为中文，或参考范文的正确译文，然后进行中译英的工作，根据自己的理解把中文译为英文，最后对照英文原文，你会发现你的译文与原文存在较大的差别，这些差别正是你写作低分的症结所在。同样的一个中文句子，仔细对比一下你使用了哪些词汇、词组和句型，原文使用了哪些，这样你的写作水平才会逐渐提高。

四、 写作：

进行完上述工作之后，在考前必须进行写作的工作，只有动笔写作，才会发现自己的问题。可以写5—10篇真题或模拟题，模仿自己曾经背诵过的精彩词汇、词组、句型、框架和范文，写出一篇新的文章。最初不要求速度，但考前一定要进行模考，半小时写出一篇120－150词的文章。写完之后仔细修改其中的语言错误，将其改的更加精彩。

英语写作基础不太好的四级考生，必须按照上述步骤严格进行；基础较好的考生学习顺序正好相反，首先写作，直接写作英语四级真题；其次中译英，在研读原文之前，进行中译英的工作，译完对比，找出差距；然后背诵；最后默写。同时可以准备自己的写作框架，应用文和论说文分别形成固定的写法，积累精彩句型。

Some people think that university should not provide theoretical knowledge, but to give practical training benefit to society.Do you agree or disagree. use your own experience and knowledge to support your idea.

Most universities and colleges spend a rather long period in fundamental theories and elementary courses. But students regard these kinds of knowledge useless, and pay less attention to them. They suggest school pay more time for practical training instead of providing theoretical lessons. In my opinion, however, theoretical knowledge is necessary. And one will definitely benefit from it.

First, fundamental theories, such as math and physics, are the basis of other knowledge. To a student who majors in automatic control, the course of control system is the most practical and useful in the future. But if he isn’t good at math and circuit, he will hardly be able to understand the principles and methods of how to control a subject or process. It is just like constructing a building. How can you imagine a spectacular high-rise without

a firm groundsill? That is, theories and practices are interrelated. We can ignore neither of them.

Second, theoretical basic knowledge provides not only the knowledge itself, but also a way that how to learn and research. University is a place for scientific research and invention. So it is necessary for students to have the skill of doing research. Seeing from another angle, science and techniques are exploding so quickly that present skills will soon be out of date. If one learnt nothing except practical skills, he would also fall behind the society. But if one could master the method of research, he would be able to refresh himself continuously with advanced technology.

From all the commentaries above, we can learn the important role of theoretical knowledge. Although pragmatism is very popular today, we should pay enough attention to the basis and principles.

导语：英语写作除了要求大家在词汇量和语法上有一定的积累外，也需要大家注意总结一些常用的写作技巧。下面是yjbs作文网小编为您收集整理的资料，希望能够对您有所帮助。

一、“功能段落”突破CET写作

诚然，六级写作是需要背模板的，但绝不是盲目地背。

整篇背诵模板不是最有效的方法，因为模板的写作思路是固定的，然而很多时候试题的命题思路可能与所背模板思路不同。因此，可能导致“所背非所考”，甚至导致文不对题，生搬硬套。

但是，无论六级写作话题如何变化，一般都对应三个或两个汉语提纲。只要按提纲要求去写相应的内容段落，就做到了紧扣主题。历年写作提纲可以总结为六种功能段落：现象描述、危害分析(弊)、原因分析、建议措施、观点阐述(观点的本质为利弊：支持方观点等于分析“利”，反方观点等于分析“弊”)、意义阐述(利)。

如果能够掌握住六种功能段落的写作实际就掌握了六级考试写作考题的最本质特征。那样的话，无论题目如何变化，我们准备都是有的放矢的。反观，死背模板容易导致生搬硬套，甚至文不对题。

二、写作短期提分方略

在了解了六级考试在命题特点的基础上，考生在备考阶段最需要准备的是两个内容：思路和表达。思路解决怎么写的问题，表达解决写什么的问题。如果拿到一个作文题目，你知道应该按照什么思路去写，又知道应该写什么表达，这篇作文就已经成功了一半。

表达积累

表达分为四个层次：词句段篇。其中篇章层面只要按照提纲要求去组织文章即可，因此篇章方面不足为虑。段落方面按照“功能段落”的六种形式去识别，也小菜一碟。

背写：思路+表达

很多同学考前也在背，背的滚瓜烂熟，脱口而出，觉得自己水平很牛!上了考场也顺利将文章写了出来，却得了一个很低的分数，为什么?因为单词都拼错了。请牢记：口头背诵得再好不等于能够写对。背写是提高写作和翻译唯一也是最有效的方法。

那么，背写什么内容哪?答案是思路和表达。思路上文中已有论述，遣词和造句的表达方面应该紧密结合功能段落来背诵有效句式和用词。考生不必刻意追求适用难词，但可以将常见词汇稍作替换：如，

exceedingly, extremely, intensely替换very;

an army of/a great many/a host of 替换a lot of;

advancement 替换 development;

positive, favorable, promising(有希望的)， perfect, pleasurable, excellent, outstanding, superior替换good;

give rise to, lead to, result in, trigger 替换cause;

harbor the idea that, take the attitude that, hold the view that替换think;

beneficial, rewarding替换helpful;

bear in mind that替换remember;

enjoy, possess替换have;

shopper, client, consumer, purchaser替换customer……

表达精彩体现在三个方面：遣词、造句、连贯。

三、复习安排建议

总体原则：先背再写、阶段总结、适当模拟。

先背再写：基础较差同学一定要先背一些功能句式和教材相关范文，然后模仿该作文的思路和表达去写。背写的目的是积累语言表达实力，同时练习书写的公正和优美。建议书写较差的考生买本英语字帖练一下书写，也许你会有意外的惊喜。

阶段总结：每过一周就要问自己几个问题：所背诵的表达可以用来写什么类型的文章?该类文章的相关词汇或表达有什么?关键词如何避免重复?请记住：没有复习，没有巩固。

适当模拟：在熟练掌握背写了六种功能段落的思路和表达之后，可以结合适当题目在写作中运用所讲所背所总结提分词汇、句式。建议大家能够灵活运用，做到一例多用。

附注：

中心句放开端

文章中心句是整个文章的主题和写作围绕的中心，通常应该放在段落的开端，这样一方面能够让阅卷老师一眼看出文章表达的主旨意思，起到开门见山的作用;另一方面可以使文章条理层次更加清晰，逻辑性强，文章的整体结构合理。中心句在作文中可以起到承接上下文的作用，放在段尾也可以起到总结全文的作用。这一方法对于写作初学者来说还是有一定困难的，因此在六级考试中，为了减少不必要的错误和损失，大家尽量将中心句放到文章的开头以保万无一失。

关键词要具体

文章的中心句一般是通过关键词来表现和限制文章的主旨思想的，所以为了突出主题，关键词需要尽量写得具体些。这里对“具体”的要求主要体现在两个方面：一方面是要具体到能限制和区分文章段落层次的发展;另一方面是要具体到能说明段落发展的方法。精确仔细地突出关键词是清楚地表达文章主旨、写好段落中心句的重要前提之一，这对考生来说有一定难度。

设问扩充内容

中心句及关键词确定后，文章的大概框架已经清晰了，这时候就需要选择和主题有关的信息和素材来填充这个框架。实质上，针对关键词测试每一个所选择的素材就是一个分类的过程。有一种常用的行文方法就是句子展开前加以设问，然后解答，即设问-解答(why-because)的方法，利用问题引出自己需要的话题再加以解答表现自己的观点，同时紧紧围绕主题。

Some people believe (argue, recognize, think) that 观点1. But other people take an opposite side. They firmly believe that 观点2. As for me, I agree to the former/latter idea.

There are a dozen of reasons behind my belief. First of all, 论据1. More importantly, 论据2. Most important of all, 论据3.

In summary, 总结观点. As a college student, I am supposed to 表决心. 或 From above, we can predict that 预测.

导语：不论从何种角度，环保都是当代世界发展不可忽视的一环。它也不再仅仅是一种措施和行动，而是一种经济行为，并带动了一系列相关的产业。下面是yuwenmi小编为大家整理的说明中国发展环保经济的状况的英语句子，欢迎阅读与借鉴，谢谢!

[坚持八条英语作文的写作守则

一、审题

我们拿到作文后第一件要做的事就是审题。审题的作用在于使你写作不跑题(如果跑题，条理和语言再好，也得不到及格分，甚至0分。)那末审题要审什麽呢?

1.体裁(议论文，说明文，描述文)

审题就是要审作文的题材和体裁。因为什末样的体裁就会用什末样的题材去写。那末体裁包括那些呢?它包括议论文，说明文和描述文。从近些年看，四级作文不是单一的体裁，而是几种体裁的杂合体。例如： Directions: For this part ,your are allowed 30 minutes to write a composition on the topicTrying to Be A Good University Student .You should write at least 100 words and you shouldbase your composition on the outline (given in Chinese ) below :

1.做合格大学生的必要性

2.做合格大学生的必备条件(可以从德智体方面谈)

3.我计划这样做

很多人说这种类型的作文是议论文。这是片面的，因为，第一段要求写"...必要性"，这说明本段体裁是议论文;第二段要求写"

...必备条件"，这说明本段要求写说明文;儿地三段要求写"...这样做"，这说明本段要求写描述文。所以在大多数情形下，四级作文是三种体裁的杂合体。

2.根据不同体裁确定写作方法

我们审题的目的就是根据不同体裁确定不同的写作方法。通过审题，我们可以看出四级作文大都是三段式。如上例第一段为议论体，第二段为说明体，地三段为描述体。而各种文体又不同的写作方式： 议论文;要有论点和论据，而且往往从正反两方面来论述。例如上面第一段的思路是：做合格大学生，会怎末样(这是从正面论述);不能做合格的大学生，会怎末样(从反面论述);所以我们要做合格的大学生(结了论)。

说明文：可以从几方面或几条来说明一个问题，就上作文而言，可以从方面(德智体)来说明合格大学生的必要性。

描述文：一"人"为中心描述一个"做"的过程。与上两段相比，本段的主语多为人称代词，他要与第二段相互应进行描述。 二 确定主题句

通过审题，我们知道该如何确定正确的写作思路。下边我们就谈如何些。第一部就是要写主题句。主题句是确保不跑题的前提，只有不跑题才有可得及格分。写主题句嘴保险的方法就是把中文提纲的各句译成英语。例如上述三段主题句分别为：

1.It is very necessary to be a good university student . (议论体的主题句)

2.There are several respects of necessities to be a good university student .(说明体的主题句)

3.What I will do in the future is the following .(描述体主题句)

如果要求句是英语就可以把它变成主题句，例如这样一篇作文：

Good Health

1.Importance of good health

2.Ways to keep fit

3.My own practice

这样的作文的要求句就可以扩充成主题句。扩充后三段的主题句分别为：

1.It is very important to have good health .(将名词 importance变成形容词important)

2.There are four ways to keep fit for me .(用 there be 句型)

3.My own practices are the following .(采用原词)

二、条理清楚

保证不跑提示写作当中第一任务，第二个重要任务就是要做到条理清楚。对于议论文来说，正反面要清楚，对于说明文来说条理要清楚，对于描述文来说，谁干什么要清楚。就拿上例Good health 来说，第一段保持正反面要清楚救应这样写：正面(With good health ,we can...)，反面(Without good health ,we cando nothing .We cant do...)

为了使文章更具有条理性，我们可以用first(ly) second(ly) third(ly)等副词，他们可以是文章的条例性更加突出。作文是主观题，想得告分就必须引起老师的主意，老师的时间很短(每篇作文只有一两分钟就要阅完)，所以我们在列调试最好不用: To be with,... after that ,...And then, ... The next , ... Thefollowing , ... As last ... 。因为用这样的词语不利于老师看出你作文的条理性。

三、保证作文符合字数要求的十二句作文法

考生一般都希望作文达到字数而又不至于写得太多，因为写得太多一方面暴露自己语言上的弱点，另一方面又会占用过多的时间。写得太多还易跑题，一个有效的方法就是十二句作文法。

我们知道，四级作文都是三段式。我们算一下，如果我们在每一段中写上四句，即主题句加两三句扩展句和一个结论句就可以了。这样全片在十二句左右，每一句十多个词，就又120-150个字。大家可以试图找一些作文题练一练。

When winter holiday is around corner,I have so many plans,but now I just like coughpotato. My sister and I sleep in the morning,my parents get mad at us.They force us to get up,we lock the bedroom door until we are both hungry.Ha... Because of final exams,our skin in bad condition,my sister said that sleeping is good for skin.Yeah,female do care about their appearence all the time. Afternoon belongs to friend.Call them out and go shopping toghter.We gossip all the people we know.This feeling is so cool,you may find that friend is so important in the world,no on can live without them. My day is simple.

In a large, I need to do as much as possible to participate in some extracurricular activities, give yourself some training opportunities, including: regularly learning, understanding and practice of the party constitution, as well as their own words and deeds, feelings, as soon as possible through the audit, to join the Communist Party of China; actively participate in school the art style of campus activities, community activities, debate, speech contest, painting and calligraphy competition, in order to fully exercise the courage and ability to display personal style. Learn something new (simple dance, basketball, table tennis etc.) but the premise of all activities, must first learn! In the sophomore year, we must learn professional skills and make full use of school libraries, outsourced bookstores and network information, expand our horizons and expand our knowledge range, so as to inspire and develop our ideas and try to design academic innovation and technological innovation. Do more part-time jobs, contact more social practice, let yourself know more about the society, lay the foundation for entering the society after graduation, and prepare for some qualification tests. The target English is over four levels.

Machine two and so on. In the third, fully ready to go for a certificate, such as securities qualification certificate, qualification certificate and professional related to finished in Sandu, for the future lay the foundation for the accumulation of experience. You have to have some capital to talk to others. In the fourth year, the goal should be to improve the job hunting skills, collect the information of the company, and determine whether you want to get it. In professionalwritingacademicarticles, can boldly put forward their own views, exercise their ability to solve problems independently and creatively; to participate in the summer and professional work experience and exchange students work experience, understand the collection of information sources, and actively try to join the network, and have alumni, schoolmates talk about the job situation in previous years. More experience, as soon as possible for your career orientation, and try to make full preparation for the employment. Besides, we also need to develop the practical skills needed by the profession. Because employers, not only pay attention to the professional knowledge and skills of college students, but also pay attention to the plasticity of college students and some potential quality abilities. Take part in useful vocational training. Vocational training includes vocational skills training. Scientific evaluation of self professional ability, professional adaptability and professional values. In general, we should constantly improve the ability to cope with frustration, cultivate self - will and shape a good personality. Only with these basic abilities can we set up their own team and lay a solid foundation for their own development.

In the University, there is a popular sentence, "the university will regret for four years, and the university will regret for a lifetime without being in love." This view is at least disagreed at the moment. It may be an inevitable process to be in love at a university, and it should also be within the plan. It doesnt matter whether its important or not. Whats important is how to deal with it well. Its not only bad for oneself, but also affects itself, and more importantly, it may affect academic study and make oneself indulge in unrealistic imagination. Im afraid its not just regret for four years.

For most university students, dormitory life is a new experience. Most students have never lived far away from their parents before coming to university. They have always had their parents to depend on for advice and guidance, and when they become university students, their lives begin to change.

There are striking difference between home life and dormitory life. Student must begin to be responsible for their own action. They must depend on themselves to get up in the morning on, time for class, to eat properly, to keep their clothes and themselves clean ,and to set aside an appropriate amount of time for study and relaxation. They must also learn to take care of their money, making sure to preserve enough for both necessities and for fun.

In general, there are both good and bad points about life in student dormitory. Often, dormitory?rooms are small and crowded. This lack of space can limit ones privacy and make it?difficult for students to concentrate on their studies. On the other hand, in a dormitory, student have a great deal more freedom than?they might have at home. They can act according to their own will and desire than to that of parents.

Nowadays, colleges and universities enroll an increasing number of students year after year. After four years of study, they have to meet more and more rivals in the labor market, usually many of them going home with no work at all, disappointed.

With more graduates and less job vacancies, students are encouraged to start business of their own when they graduate from university. They may start take up anything they are interested in, make decision on their own, and obtain the fruit of their own labor. In this way, graduates will become more independent, imaginative and creative.

Yet this process should be supported by our government. The government should provide special policies for these students, and when necessary, guide them onto a correct road.
