What does friendship mean

What does friendship mean? There is no definite answer. An eternal theme in literature, friendship is also indispensable in daily life.

Friendship is to our life what salt is to dasher. When you are happy, friendship is just like adding flowers on the brocade; when you are sad, friendship is a dose of consolation; if you are in trouble, friends will surround you and remove the barriers for you; if you have a hard nut to crack, you can turn to friends for help. W e admire the great friendship between Marx and Engel, which firmly combined them and pushed them forward on the road to exploring and fulfilling Communism.

Friendship isn't almighty, but no one can live happily without it.

Private tutoring is “in”.

A recent investigation shows that about 80 percent of pupils have private tutors.Such a popular practice indicates that people are attaching greater importance to education. Many parents, for various reasons, missed the chance of obtaining a good education. When their children meet with difficulties in study, they are helpless. Private tutoring is the only solution. As private tutoring is usually one-to-one, the teacher knows the strong points as well as the weak points of the pupil clearly.

However, private tutoring has its own disadvantages. For one thing, it takes up so much of the pupils’time that they can hardly find enough time for rest and entertainment, which are essential for their physical and mental health. For another, some teachers, busy “shuttling” from one family to another, tend to neglect their regular teaching duties. What’s more, some teachers are eager to help pupils do well in the test, offering the so-called tips for test-taking rather than help them acquire what is more meaningful.

Generally speaking, its disadvantages outweigh its advantages. Greater emphasis should be laid on classroom teaching and practice, on the improvement of teaching quality and on the tapping of pupils’potentials. Only in this way can a new generation be healthily brought up.

Fast Food

Fast food is becoming more and more popular in China, especially among children and teenagers. T oday, nothing is more representative of the fast pace of modern society than fast food. There are several reasons for its popularity. First, it is quick and convenient. Go into a fast food restaurant, and your food will be ready in a minute. Y ou can satisfy your hunger instantly. Precious time won't be wasted in waiting-in-line to order or waiting at your table for your food to arrive. Second, its popularity is also attributed to the clean food, the excellent service and the comfortable environment of the fast food restaurant.

However, I think that fast food isn't healthy enough because it does not compose a balanced diet and is low in nutrition. Doctors suggest that people should avoid eating too much fast food. Although home cooking is time-consuming and following washing-u p tiresome, it offers healthy and delicious meals your body likes and needs

Now the income gap is getting wider and wider. In some privately owned firms,

joint-ventures, or foreign-fund companies, an executive’s yearly income is ten times or even a hundred times as much as an ordinary worker’s.

Faced with this situation, people will undoubtedly have different opinions. Some believe that it benefits the social and economic development since driving force is often derived from the gap. In other words, the gap inspires people and gives a push to advancement. Others speak of its side effect: income gap is often the root of social unrest and also contrary to our country’s principle.

From my point of view, while it is true that the income gap may stimulate the social development to some extent, it causes trouble as well. An income gap that is too wide for most people to bear can neither contribute to the stability of a country nor promote its economic development. Therefore, while we are advocating the rapid development of our country, we should tolerate the narrow income gap but narrow the wide one.

A Letter to the Minister of Education

Dear Minister of Education,

I am a college student and I would like to suggest that students should be given several shorter breaks through the year instead of the traditional long vacations. The reasons why I am in favor of it are as follows.

First, students must work very hard at their studies. If they work for too long without a break, they may become overtired and discouraged. They may lose their enthusiasm for learning. Second, a very long vacation is not necessary. Students can recharge their energy in a few days rather than weeks.

Furthermore, many students do not use a long vacation wisely and just waste their time instead of doing something meaningful. And last but not least, vacations give students time to explore other interests and perhaps apply what they have been learning to the real world. If they always focus on their studies. They may lose touch with what is happening in their society.

In conclusion, I believe that students today would benefit more from several short vacations than they do form two long ones.

I do hope you can take my suggestion into consideration and make a final wise decision.

Y ours Sincerely

Early in senior high school, we longed to be enrolled in a university. Now the dream has come true. But how do we college students like our campus life?

Certainly, some relish it, finding it colorful and rewarding. Besides study, they spend considerable amount of time improving themselves in various aspects. Y et others do not think much of their college life, thus do not benefit as much. In their eyes, the university is just a bigger high school. The only difference is that they have more time at their disposal without parents looking over their shoulder.

As to me, college life is ideal if only I have abundant books to read, some bosom friends to keep me company, a couple of conscientious professors to instruct me, and an easy access to the Internet.

Dear victims,

A week ago, I was shocked at the news about the earthquake in Y ushu. And I’m very sorry to hear that this earthquake was the greatest disaster after 1949. And there are 40075 people who are found dead in the disaster till now and there have been more than 500 million people who are homeless. The floor was ripped through, many blocks and houses were seriously damaged, and even were as flat as a pancake.

I’m deeply moved by the volunteers and the international rescue teams who are in the frontline. I, standing for my school, comfort your victims and survivors with our warm heart. Moreover, we contribute a large amount of money to you. And our school will try our best to help you.

Last but not the least, I hope we all have the confidence to rebuild your home after the disaster. Only when we have the perseverance can we defeat the natural disaster.

Good luck and best wishes to you!

Y ours sincerely

I t’s very hard for college graduates to find a job, of course harder to get an ideal job. In fact, many factors contribute to the unfavorable situation.

First, more and more students can go to college because of the being fast improved high education of China. As a result, there are more graduates every year. However, job vacancies don’t increase that fast. More people, less food, which is the exact description of the hard condition. Second, more and more people go on to pursue their master and doctor degree; more and more Chinese oversea students come back to China to hunt better working chances. It is sure that the competition is more and more fierce. Third, because of the fast development of science, technology, economy, society and the interchange of different nations, all units have higher requirement of their employees, for example, stronger ability and higher degree.

In addition to the factors above, there are still more which bring hardship for graduates to find jobs. Nevertheless, how to solve the problem is more important. It is a good idea for the graduates to learn more knowledge with a higher degree and to practice and improve their capability of dealing with all kinds of situation, organization, having good terms with others and cooperative spirit. Besides, the government should try to and encourage all units to create more job vacancies for the college graduates. Of course, the graduates should have a proper attitude towards various jobs, but not always pursue those with higher payment.

Every year, college students are inspired to help students with their study in underdeveloped areas in china. They have been trying their best to impart knowledge and offering help to those students who are so eager to learn.

This volunteer practice has been beneficial in two aspects. On one hand, college volunteers are really devoted to the cause. They have opened the eyes of students in underdeveloped regions to the outside world by bringing them new knowledge and thoughts. As a result, they are extremely welcome and respected by the children there. On the other hand, college students have received a rigorous training by adapting to the harsh living

conditions. They are learning how to deal with difficulties and face challenges as well. What’s more, by any me ans, this volunteer experience will be always a valuable asset in his or her life.

In my opinion, every Chinese citizen is responsible for the development of education in china. And we college students should take the lead in response to the appeal for offering aid to children in poor areas.

Dear Sirs,

I'm Li Ming, a sophomore majoring in English at XX University. I read in yesterday's newspaper that you are looking for a part-time secretary and I think I'll prove to be a real find for you.

During the past two years at university, I’ve taken over 18 compulsory and optional course, and have according improved my ability of English listening, speaking, reading, writing and translation considerably. Besides, I have learned a lot about foreign relations and trade. At leisure, I always try to grasp every precious opportunity to practice English with native speakers. As a matter of fact, I've already tried some translation and interpretation jobs. I once worked as a temporary interpreter at the East China Export Commodities Fair. In addition, during the past two years, I have been working as a part-time tour guide. My jobs offered me good opportunities to improve my English and work competence and I enjoy them very much.

Two weeks from now, I will be on holiday again. If you can grant me the honor to work for your company as a secretary for two months, I'd feel obliged. Thank you for reading my application letter. I'm looking forward to your reply.

走进都市农业感受现代科技 --"大东农业观光园"基地实践活动 设计者：大兴区第九小学窦雪征 指导教师：大兴区教师进修学校柏东河 ( 2008-05-27 13:40:19 ) 一、环境分析 我国是个农业大国。当前，在农业科技领域，中国不断缩小与发达国家的差距，农业科技部门在生物技术、高新技术、基础研究方面均取得较大进展，植物细胞和组织培养、花药培养、单倍体育种及其应用研究处于国际先进地位。但是，作为国家希望的小学生却对我国农业的了解知之甚少，甚至有的学生只认识餐桌上的蔬菜，田地里面的蔬菜就不认识了。而且由于社会环境的影响，学生对于农业生产的认识非常极端，认为农业生产只是辛苦的体力劳动，对其间蕴含的高科技文化知识基本不了解。 大兴区作为北京市的一个远郊区县，拥有着得天独厚的农业教育资源，在我们的身边就有向"大东农业观光园"这样的一个很好的农业教育基地。在大东农业观光园里面充分体现了现代农业。它目前拥有现代化日光温室34个，塑料大棚34个，露地80亩，为观光采摘、实验、示范、生产提供了场所。农业观光园里引进福建有机茶叶树，通过土壤改质能使其在北方正常生长；蔬菜嫁接的试验技术；大棚中的科学技术，如：所有地面具备节能、日光温室跨度大、内设供热、微喷、保湿、补光等多项功能；另外园区内设有科普知识长廊，为学生了解我国农业的历史文化和发展，创造了很好的条件。此基地实践活动适合小学高年级学生，他们可以在基地里面，进行参观、体验、学习了解高科技农业技术。通过基地的实践活动，可以增长学生现代农业知识，提高劳动能力，体验劳作的艰辛，培养学生良好的道德品质。可以很好的促进学生学习方式的变革，使学生直接从事实践性主题活动，实现学生自主学习和直接体验为主的学习方式，从而不
