Spring girl walked with light steps reluctant to leave. She turned around, the beautifulSummerquietly came to our side.

Although I like spring, I like summer better.

Summer is hot. The hot sun hung high in the air, the heat and sprinkle to the earth. I like summer, because we can wear thin clothes, can be lightly dancing with the wind.

Summer is all grown up period, every day in the growth of plant. You see the green vine beans overnight in scaffolding, can grow very high. Zhu Zilin, you listen to the voice of sorghum fields, in a bar in the sound, more than half of the night. The scenery here is so beautiful!

Summer is relaxed. A lot of people are like holding a fishing rod to go fishing. In the morning the lake quietly, without a sound, as in the school classroom, even a needle falling on the ground could be heard. At noon, the old people sitting in the shade under a tree, they take a leisurely fan fan, beside the dog vomit a bright red tongue, slightly closed eyes lazily lying on the ground. The birds and cicadas in the tree bark incessantly, as if to tell people, summer is so leisurely and comfortable.

Summer is beautiful. The green grass and colorful flowers swaying in the wind. A variety of flowers open. Lake in the beautiful lotus is beautiful! Pink and white flowers nestled in the lotus leaf side, like a shy little girl. There are a lot of dew on a lotus leaf, the sun came out, they are like the ellipsis, the lotus leaf "patter" slipped into the water.

Ah, summer is beautiful, how charming! Summer, I love you!

In this picture a man rudely opens a garbage can and violently throws all kinds of waste into it. however, the box is not an ordinary trash can, but is, as a matter of fact, the earth. it is where survive, breed, and prosper. but as the drawing indicates, earth does not receive an equal repayment. quite the contrary, one of the biggest "gifts" humans return to earth is an unbelievable amount of trash.the picture purposefully points out a kind of pollution that arouses little public attention, that is, garbage. the past century has witnessed an unprecedented increase in garbage output, most of it technological products that are difficult to be decomposed through natural processes, such as plastics and glass. furthermore, a recent report released that several major chinese cities are already surrounded by circles of trash in the suburban areas, polluting air, water, and earth.

Hence, the issue of waste pollution needs to be addressed as one of the priorities that demand social efforts. only through a holistic system of trash disposal can this problem be fully solved. moreover, we should advocate a more frugal lifestyle so as to reduce the growing scale of waste pollution.

Help others you also can be joyful, is a trivial things will also make yourself feel happy.

Remember when my third grade, a language examination it if I know "helping others, happy yourself" meaning.

This day I hurried from the drawer take out three ball-pens, just got in the classroom. Come to the classroom soon bell rang "000" class, the teacher also follow here, in this moment students stopped discourse, from the bag out books to sit quietly on the desks and chairs, books. Disguise

"Start the test" the teachers words sound just fell, well put the desk retrieval empty, they left a pen, a cushion the cardboard.

In the exam, everyone was doing at, then my leader patting my shoulder, side whispered, "xiao fine you have a few pen? Can you lend me one?" Borrowed, "Im not happy about it, but I think of helping others, happy yourself, helpful, my hands and flat, not to hear my words, automatically put pen handed it to my leader.

After the test, when I heard leader said to me, thank you when I feel alacrity.

The day I understand the "helping others, happy" meaning. As long as you help others, in your most helpless time they will help you.

China, a country with an ancient civilization, self-help is the traditional virtue, as the most beautiful songs rap "a star willing to help others heart, the most happy is a help others..."

As we all know, college is a place where students can cultivate their professional skills, but more and more students now lose their heart in study. They are addicted to playing computer games or other activities. If the Internet is not turned off, they would rather stay up to play than go to bed. Why this phenomenon gest so common? How really should do to college students?

我们都知道大学是一个可以培养学生的专业技能的地方，但现在越来越多的学生无心学习。他们沉迷于玩电脑游戏或其他活动。如果没有断网，他们宁愿熬夜玩电脑而不是去睡觉。这种现象为什么如此的普遍?大学生真正应该怎么做?

Maybe I can explain the first question with some reasons. Nowadays, college students are under more pressure from school work and coming employment. On one hand, they should try to pass the tests to get credit; otherwise they can’t get the academic degree. They may be defeated by the challenges or difficulties. They just want to do something exciting to escape the problem what they faced. On the other hand, college life is more flexible. Students could choose various ways to study. If they can’t make good use of time wisely, the result is that they will get lost. Students give up easily and can’t behold on consistently and persistently.

也许我可以解释第一个问题。如今，大学生学业、就业的压力越来越大。一方面，他们应该通过考试来获得学分;否则他们不能获得学位证书。他们可能会被挑战或困难打败。他们只想做一些令人兴奋的事来逃离他们所面临的问题。另一方面，大学生活更灵加的活。学生可以选择各种方法来学习。如果他们不能充分理智地利用时间，他们就会迷失。学生轻易放弃，而且不能有始有终、坚持不懈。

So the most lack to college students is willpower .Just as the old saying goes, “where is a will, where is way.” If college students want to do something perfectly, they should stick to it every day and do not let other things distract their aims. Then they will be a great winner in college and life.

所以大学生最缺乏的是意志力。正如俗话所说，“有志者事竟成。”如果学生想要做好某件事，他们就要每天坚持做，不要让其他的事情分散他们的目标。这样他们在大学生活中将是一大赢家。

Another deep impression of my university is her creativity and profundity. As is known to all, she has a wide range and comprehensive style. No wonder I can enjoy the multi-ceolored life here. Every school year a diversity of competitions and aetivities are held and a large number of students take active part in them. I do appreciate such a style, and in my minds eye, she resembles a tall tree silhouetting with all shapes of branches while stretching far into the blue sky.

Undoubtedly there is a world of difference between university and high school. University students are supposed to enjoy more freedom to develop themselves. However, Fudan seems more concerned about the efficient cooperation and teamwork among students as to prepare them for the competitive society. I believe upon graduation I will be equipped with abundant skills to face more unknown challenges.

After all, in my opinion, university is for more cultivated character, richer knowledge and greater abilities. Thats why I chose Fudan. She provides me with what Ive dreamed of.

Now all kinds of successes are in sight every day, and all I have to do is endeavor for a more beautiful future...

Henan has a humid warm-temperate climate. Dry and windy in winter and spring, the province is hot and rainy in summer and bakes in strong sunlight during the autumn months. Rainfall averages about 600-1000 millimeters increasing from north to south, as does the annual temperature which increases from about 12.8C in the north to 15.5C in the south.

Henan province is considered the cradle of Chinese civilization due to its location on the Yellow River. This rich historic heritage has endowed Henan with numerous historic treasures, from primitive dwellings to earliest wheel thrown pottery. The remains of some of the earliest human settlements have been unearthed here, including the over 7000-year-old Peiligang Culture Site, the 6000-year-old Yangshao Culture Remains and the 5000-year-old Dahe Culture Remains. All these cultural remains have profound significance in the history of Chinese civilization.

Luoyang City has been the capital of nine dynasties since the time of the Eastern Zhou Dynasty (770BC-221BC). There are many historical sites to be viewed in Luoyang as well as the opportunity to purchase replicas of the famed Tang three-glaze horses. Luoyangs Longmen Grottoes, famous for its grand treasure trove of Chinese Buddhist statues, are located 12km (7 miles) south of Luoyang. First sculpted and chiseled around 493 AD when the capital of the Northern Wei Dynasty (386-534) was moved from Datong City to Luoyang, the grottoes of Luoyang house an awe-inspiring collection of sculpted Buddha and other religious subjects.

Kaifeng, one of the ancient capitals, also boasts the following buildings worthy of a visit: Iron Pagoda (Tie Ta) of the Northern Song Dynasty (960-1127), Dragon Pavilion (Long Ting) - site of imperial palace of the Song and Jin dynasties - and the 1400-year-old Xiangguo Temple which is one of the most famous Buddhist temples in China. Also on view in Kaifeng are ruins of the Shang Dynasty, an important part of human cultural and historic heritage. The Shang Dynasty Ruins, also known as the Yin Ruins, are famous because of the unique style of the large palace and its grand mausoleums, in which emperors of the Shang Dynasty are buried. The bronze vessels of the Shang Dynasty, which were both finely decorated and popularly used by the citizens of the Shang Dynasty, are well-known at home and abroad.

No classical work could pervade every cubic centimeter of air with such cultural fragrance but she.

No judicious sage could merge various elements as a magnificent poem but she.

No green tree could consist of vivid cells arousing every hearts anxiety for being young forever but she.

She is my university Fudan University.

The first time I entered the campus as a freshman, I was deeply attracted by her cultural atmosphere and historical connotation. Fudan is a graceful lady who is accustomed to serenity but meanwhile each action of hers outpours her innermost tern perament. Apparently it is worth every effort to probe into her world for the sake of both physical and mental enrichment. Her humanistic spirit inspires me to care for everything around, even the most trivial one.

On the other hand, catching up with the times, Fudan is modern and smart. You see, the many age-old buildings here are actually great libraries and labs. Scientific and technological developrnent is easily smelt in the air,because she never lags behind the world.

Fabulously, such a historical and scientific school is far more than an operational mechanism. Her everlasting youth and vigor beam through every corner of the campus and the young in school vivify every piece of concrete and wood here. What makes me happy and strong is that it perpetuates me with unfading energy. And it is definitely beneficial for me to be granted enthusi。

A little boy was very naughty and would not say his prayers before going to bed.

One day his father warned him that if he kept doing so. He would not go to heaven. The boy cried noisily and said, "I dont like to go to heaven alone. I want to go with you and mama."

有个男孩非常顽皮，不肯在睡觉前做祈祷。

有一天他的父亲告诫他说，如果他老是这样，就上不了天堂的。男孩大哭起来：“我不喜欢一个人上天堂，我要同你和妈妈一起去。”

College is always considered as a turning point in our educational career and life. I would use adaptationas the key word when describing my first year at college.

As we enter a new school, we first have to adapt a new environment and meet new people.As we leave home and move into the school dormitory, we need to learn to live and get along with other people who have different living habit. And as we start a higher level education, we need to adopt a new way of study. Teachers are no more like the ones in high school that will push us to learn.

Instead, we have more options and spare time to do what we want.

I am glad that I have overcome the difficulties and adapted the new life of college. I have achieved a lot more than I expected at my first year of college. First of all, I have made new friends who share the same hobbies and met new teachers who inspire me in all way. Secondly, I have become more independent. I have got used to a new way of study and often study different things by myself. I can take care of myselfwithout parents being by my side all the time. Last but not least, I have learnt to make full use of my time. I believe time management is a very essential skill in college life as we have more freedom than ever before. It has helped me not to waste time and turned me into a well-organized person.

My first year at college is excellent and I really appreciate all that I have learnt this year.

it is true thatSummeris hot, very hot. but the wicked summer sun is nothing to me, for i dont usually go out. what i like to do best during the long summer vacation is to stay in my own little room and read. i love to read, but during the school year i could hardly find a free moment for reading. endless assignments press down upon me like a mountain. i feel confined and imprisoned. once the summer vacation comes, however, i have all the time in the world to read and read and read. i read everything i want to read. i read to my hearts content. my room maybe small, and the sun maybe hot, but im free, im happy, im really living! oh, how i love summer!

When students are going to high school, they are under great pressure,

because their main goal is to enter the college, so they need to work so hard.

The school will test them so often that they want to get the best scores.

Cheating on the exams is many students’ choice, as they could not do well on the

exam, so they want to find the confidence by getting the high marks. Other

students even buy the exam answers, what they do is totally wrong. Frist, it

will cost students a lot of money on buying the answer, it refers to spend their

parents’ money, it is not easy to earn money. Second, the answers that students

buy are not accurate all the time, most of the answers are wrong, students are

easy to get cheated. Students should work hard to improve their study.

Where possible, reduce the use of "which," "who" "that" "whom" "whether... or not" etc.

Protecting the Environment

With the improvement of our living standard, more and more people can afford a car. As a result, our roads are more often than not crammed with cars. However, with more and more waste gas being discharged by the cars, the problem of air pollution becomes even more serious. So nowadays we advocate to lead a low-carbon life.

My suggestion is we should ride bikes more often instead of driving cars.By riding a bike, we can not only exercise our body but also protect our environment. Why not have a try, my dear friends?

Hello everyone！ My name is * * *, from Jiangsu * *. Very pleased to enter the academic atmosphere of the * * * * college. After all, for every student, public undergraduate is a dream that is worth working through. Today, it is becoming the youth of the post, dream of the stage, the struggle of the blue sky.

For this was rooted in the heart of the dream, we work hard, we fought in the busy high school life, we only know must strive to finish each paper, do well every quality inspection, in each examination room are outstanding. We dont even have time to ask ourselves if its going to be hard work.

Today, I finally arrived at * * * and came to the beautiful campus of the university. Actually, in March of this year, I stepped into this city with a long history for 4 times. However, the legend of the picturesque scenic spots: Dr. Sun Yat-sens Mausoleum, Mochou Lake, the Qinhuai River, Confucius temple, I never want to see. Those famous snacks, I did not want to have a try. I dont want to go shopping in those busy commercial centers in Xinjiekou.

Why? Because I am very clear, I came to * * *, the purpose is to participate in the art of radio and television director of the examination. I remember when I gave myself a chance to choose more, and in the confused eyes of my teachers and classmates, I often played the violin on my back, and took the south train at 4 in the morning.

What kind of day is that? While at the same time to course review, while also practicing the violin concerto butterfly, while reciting the historical geography textbooks, while also have time to read reviews, stories, practice commentary, prepared speech. Even with some basic drawings, I dare not relax. You may know: at Nanjing Arts Institute was next to a park, I took the examination room to see from the south, first, look at the list, and then to go to the provincial exam retest, located south Normal University, I dont know how many times through to a total of 8 times, this park? Or maybe the 10 time? But even today, I dont know what the name of that park is

When the Nanjing Arts Institute professional examination scores down, the provinces fifth results did not bring me joy. I am still in learning, in practice, a tiny bit are not slack. The teacher said, "you have got a good result in the cultural class. Why do you want to do art?" Students say: your violin level already by the China Conservatory of Music grade 8 examination, why practicing until late at night? I dont know how to answer. I just have to try and even try my best. In order to dream, in order to be able to enter the University hall.

Finally, my dream came true. I love art, but I love Chinese language and literature more. Although I gave up art, but art has shed sweat and no waste, because art is able to help us better understand the literature, literature and art combined with each other, a beautiful flower, bear the fruit of happiness.

I sincerely hope that with the help of teachers and students, I can bring my special skills in art field into full play in Chinese language and literature. We can have the opportunity to contribute to our professional development and the development of our school.

Thank you all!

when i was in high school, I had to study all the time and hardly had spare time to do what i wanted to.Besides, I had to focus on my textbooks and doing exercise again and again. Therefore, I had little time to read magazines and novels and watch TV. what was worse, I couldnt play with my friends a lot, which I couldnt stand the most. In a word, all i did in high shool should be considered for the College Entrance Examination.

However, my college life is totally different from the life in high school.I can arrange my time freely. I spend most of my time reading in the library, where I can open my eyes and broaden my mind.In my free time, I also join some clubs,where i can make a lot of friends of different majors. My teachers in college are so kind and knowledgeable that they not only teach us knowledge but also how to be a person and how to get on with others. In addition, there are more opportunities for me to improve myself.

I believe college life is an important stage in my life. In college, i can learn how to learn by myself, how to get on with others, how to live independently.College provides me with a stage where i can show myself and be myself.

当我在高中的时候,我不得不学习,几乎没有业余时间做我想做的事情。除此之外,我必须专注于我的课本和一次又一次的锻炼。因此,我很少有时间读杂志和小说和看电视。更糟的是,我不能玩我的朋友很多,我最不能忍受。一句话,我所做的在高学校应该考虑高考。

然而,我的大学生活是完全不同于高中的生活。我可以自由安排我的时间。我花大部分时间在图书馆看书,在那里我可以打开我的眼睛和扩大我的脑海里。在我空闲时间,我也参加一些俱乐部,在那里我可以赚很多不同专业的朋友。我的老师在大学里是如此的善良,知识渊博,他们不仅教我们知识,还如何成为一个人,如何与他人相处。此外,还有更多的机会让我提高自己。

我相信大学生活是我人生中一个重要的阶段。在大学,我可以学习如何学习,如何与他人相处,如何独立生活。大学为我提供了一个舞台,我可以展示我自己,做我自己。

You may feel that college life is boring. We do not know how to deal with the plenty of spare time. But I think the college life will become wonderful as long as you make it meaningful.

In your spare time, you could play basketball, football and so on. Doing sports is very interesting and good for your health.

In fact, you can do anything which you are interested in.Do not be nervous.We are friends.

Studying in college is a brand new start of our life.You can continue to study hard for the better scords. Libary is a good place for students to study in. If you want to show your talents and skills you can join in all kinds of activities.

In a word,college life is wonderful!

你或许会认为大学生活很枯燥，你不知道如何处理这么充足的空余时间。但是我认为只要你过得有意义大学生活会变得非常精彩。

在业余时间，你可以打篮球，踢足球等等，做运动是很有趣的，并且对你的健康也有帮助。

事实上，你可以做任何你喜欢做的事情。不要紧张，我们是朋友。

在大学里的学习是我们生活的新起点，为了好成绩你可以继续努力学习。图书馆是个学生学习的好地方，如果你想展示你的天赋和才能，你可以参加各种各样的活动。

总而言之，大学生活是非常精彩的!

There is a famous saying goes like that “Knowledge is a treasure, but practice is the key to it.” This saying shows the relationship between knowledge and practice vividly.

As far as we know, if we don’t have corresponding knowledge of some fields, we cannot do well in the fields. There are innumerable examples to illustrate this point. For instance, a singer can sing well only if he or she possesses musical knowledge; a dancer can dance well only if he or she knows how to dance; a worker can get the job well-done only if he or she is familiar with the basic principles of the job, and so on. But in turn, if we do not apply what we have known to practice, knowledge cannot play its role. For example, if we have learned different methods of cooking vegetables, but we do not cook, then the different methods of cooking vegetables do not produce value for us.

Therefore, if we do not have knowledge, we have nothing to practice, but if we have knowledge without putting it into practice, knowledge is of no avail. So we should acquire as much knowledge and put it into practice.
