书是人们不可缺少的一部分，高尔基也曾经说过：“书是人类进步的阶梯。“

书，赋予我知识、赋予我智慧，看书是我了解到黄德甜老师所写的《语重心长》通过这本书，让我懂得了不少的人生哲理。

在我读完《语重心长》这本书后，我才发觉到书他是我们知识的一片海洋，能与书为友是最庆幸的事，在《语重心长》里，我读懂了里面的内容，是他让我明白了语重心长这几个字的理解，在生活中的我，仍然是要懂得尊重师长、尊重父母，他们的话，我们要听，因为他们的见识比我们多，所以，他们的学识、技能也比我们强;因为他们十分关爱我们，所以，他们才会反复叮嘱我们，我们千万不要自以为是，不要像一些人，在校不尊重师长、在家不尊重父母，而经常与师长、父母顶嘴，从不去想想，师长、父母是为了他好，只会心里埋怨自己的父母与师长，难免有时师长、父母是会说错批、评错你，那也要在适合的场所纠正，和必须等对方冷静下来，才和平地去谈判这件事情，而不要在对方还在气头上去顶撞他们，这样只会更加的让他们更怒气，只有心平气和、冷静才能解决问题，古句也有说国，君不闻“不听老人言，吃亏在眼前。”

Everybody knows that there is serious problem of water pollution on the earth. Yes, water pollution is increasing.

Look! The water in the river is getting dirtier and dirtier. Most of fish in the water have died, and we can’t swim in the water.

My grandfather says, when he was very little, the water in the river was very clean. He often swam in the river with his friends.

That was before, but now we can’t see such clean rivers. Let’s protect the water from pollution, because we can’t live without water. The water is really important to us all.

How to keep a good relationship with parents

In my opinion, I have too many rules at home. My parents never allow me to go out with my friends at night. They don’t allow me to choose my own clothes, either. And they pay too much attention to my exam results. I think my parents don’t quite understand me.

However, I try my best to understand them. Although they don’t allow me to make my own decisions and give me too much presure, I know that it is because they really love me and want me to have a bright future.

In order to keep a good relationship with my parents, I study hard and listen to them. I talk with them as friends, and always tell them my troubles. I also help them do some housework.

The animal is the friend of our human beings. We live in the same earth. Animals and human beings can’t be separated from each other. But some animals are getting less and less. So it’s necessary for us to protect animals, especially wild animals. Some people kill wild animal because of money. It’s illegal. Beside, because of the development of society, human needs more space to live in, so we explore the forest. Animals have less space to live in. The number of wild animals decreases year by year. It’s high time to take actions to protect wild animals.

动物是人类的朋友，我们共同生活在地球上。动物和人类不可以彼此分离。但有些动物的数量越来越少，所以我们有必要去保护动物，特别是野生动物。一小部分人为了赚钱而去猎杀野生动物，这是违法行为。此外，由于社会的发展，人类需要的生活空间，所以要开发森林。然而动物的生存空间却变少了。野生动物的数量逐年减少，现在该是采取措施保护野生动物的时候了。

News, used to be the most dont like to see it. Since the childhood has been like watching cartoon and foam. Now over the years is already 15 years old girl, the adults always said I dont understand, I also often because of his bad temper, or not doing things. "Knowledge too little" finally let me find the dawn, from then on began to like the news.

Compared to the past, only reading does make me understand a lot of knowledge, also became the academic leaders, but its a downright failure in life. While reading can also know society, but after all the writers praise is the truth in life, and that I love watching cartoons, and eulogize justice and goodness, degeneration and reject evil. In such an environment, my heart has been living in the white cloud, so that as the growth of the age, heart is still very naive. But I will contact with the reality of society, the essence of this society is not absolutely fair, not cheated can only let oneself become strong. But when he does not know this, just complain, disposition also become bad. Fortunately, when I was going to despair, when the news took me, no let me into the who also do not know to have bottomless pit.

Know only after watching the news of the worlds largest and I small. The content of the news is very rich, I also have different preferences, from country to country, down to between people. I see from a real case: "some of the good qualities: honesty, integrity, good Samaritan, wisdom... how important it is for this society!

新闻，以前是最不喜欢看的。从小到大一直喜看动画片和泡沫剧。现今过了年已是十五岁的大姑娘了，大人们常说我不懂事，我也常因自己脾气不好，或是不会处理事情而烦恼。一句“见识太少”终于让我找到了曙光，从此便开始喜欢上新闻。

对比以往，只读书确实让我懂了不少知识，也成为了学业上的佼佼者，但在生活上却是一个失败透顶的人。虽然读书也可以认识社会，但毕竟作家们歌颂的都是生活中的真善美，以及那我爱看的动画片，也是讴歌正义和善良，贬低和排斥邪恶势力。在这样的环境影响下，我的心一直生活在洁白无瑕的云端，以至于随着年龄的增长，心确仍然很幼稚。但我终究要与现实的社会接触，这个社会的本质就是没有绝对的公平，要想不吃亏就只能让自己成为强者。可惜当初的自己并不懂得这点，只是一味的抱怨，性格也变得恶劣。幸运的是，当我快要绝望的时候，新闻拉住了我，没有让我滑向那个谁也不知道有没有底的深渊。

在看了新闻后才知道世界之大与我之渺小。新闻的内容很丰富，我的喜好也不尽相同，上到国家与国家之间，下到人与人之间。我从一个个真实的例子中看出：“人的一些美好的品质：诚信、正直、见义勇为、智慧……对于这个社会是多么重要!

One of the most memorable time I travel is to go to Ocean Park in shenzhen. As soon as I went in I jumped with joy, wow, a towering building, how so like a private house, I began to doubt. The house was full of praise for me.

We went to the aquarium, there is a ferocious shark, the lovely dolphins, timid sea turtles, Marine animals! Let me be during pick up, walk to the ocean theatre, dolphins, sea lions performance, clown diving is the most wonderful, funny, lovely clown, jumped into the water from the diving platform, all wet and there is a clown jump into the water, some threw a life buoy to another clown head,... .

We came to the seaside to swim, the water of the sea wave to wave to me, ah! So comfortable! Washed away by the sea water to the sand of the sea, the foot on the beach, soft, feel good!

We picked up a lot of shells on the seashore, different shape, big and small, triangular, 栯 round, color variety, beautiful!

After dinner, we again to the beach to catch crabs, found a small crab, I quickly caught it by hand. Ah! Is really a big harvest, we caught six crabs altogether. We went happily back to the hotel.

The tour that I learned many knowledge, also is my most happy one.

我最难忘的一次旅游就是去深圳海洋公园。我一进去就高兴得跳了起来，哇，一座高大的房屋,怎么这么像私人住宅,我开始疑问了。我对这间房屋赞不绝口。

我们来到海洋馆，里面有凶猛的鲨鱼、可爱的海豚、胆小的海龟，海洋动物真多!让我目不睱接，走着走着来到了海洋剧场，海豚表演、海狮表演，最精彩的是小丑跳水，滑稽、可爱的小丑，从跳水台上跳到水里，全身湿透了，有一个小丑跳着跳着掉到了水里，有的把救生圈丢到了另一个小丑的头上，......。

我们又来到海边游泳，海水一浪接一浪地扑到我身上，啊!真舒服!海水把海边的沙冲走了，脚踩在沙滩上，软绵绵的，感觉真好!

我们在海边捡了很多贝壳，形状各不相同，有大的、有小的、有三角形的、有栯圆形的，颜色多种多样，美丽极了!

吃过晚饭后，我们又到沙滩捉螃蟹，发现了一只小小的螃蟹，我迅速的用手把它捉住了。啊!真的是大收获，我们一共捉到六只螃蟹。 我们就高高兴兴地回到酒店了。

这次旅游使我学到了很多知识，也是我最高兴的一次。

Knowledge can be acquired from many sources. These include books, teachers

and practical experience, and each has its own advantages. The knowledge we gain

from books and formal education enables us to learn about things that we have no

opportunity to experience in daily life. We can study all the places in the

world and learn from people we will never meet in our lifetime, just by reading

about them in books. We can also develop our analytical skills and learn how to

view and interpret the world around us in different ways. Furthermore, we can

learn from the past by reading books. In this way, we won’t repeat the mistakes

of others and can build on their achievements.

Practical experience, on the other hand, can give us more useful knowledge.

It is said that one learns best by doing, and I believe that this is true,

whether one is successful or not. In fact, I think making mistakes is the best

way to learn. Moreover, if one wants to make new advances, it is necessary to

act. Innovations do not come about through reading but through experimentation.

Finally, one can apply the skills and insights gained through the study of books

to practical experience, making an already meaningful experience more

meaningful. However, unless it is applied to real experiences, book knowledge

remains theoretical and, in the end, is useless. That is why I believe that

knowledge gained from practical experience is more important than that acquired

from books.

Nowadays, any Chinese can enjoy the luxury of owning a private car - if he or she can afford it. Having a car of your own means no more traveling to work on crowded buses or subway trains, and you can drop off the children at school on the way. Moreover, it also means that you can enjoy the weekends and holidays better, because with a car you can go to places where the regular buses and trains do not go, and so you can find a quiet scenic spot with no crowds.

However, there are drawbacks to owning a car. For one thing, with the increase in car ownership in recent years, the roads are becoming more and more crowded, often making the journey to work more of a nightmare than a dream. For another, it is not cheap to run a car, as the prices of gasoline and repairs are constantly rising, not to mention the prices you have to pay for a licence and insurance coverage.

Having considered both sides of the argument, I have come to the conclusion that the advantages of owning a car outweigh the disadvantages. Therefore, it seems to me that China should increase its output of automobiles and enlarge the private car market. The result would be that cars would become cheaper, while at the same time the extra demand would encourage the auto industry to produce more efficient and family-oriented vehicles.

My birtiday is on 24th May. I always have both happy and sad feelings on my birthday. Why I am happy? I have group of friends that come over to celebrate with me.

I feel so sorry for my mother for what she had suffered. But I promise her, I will take good care of her when I have that ability.

我的生日是5月24日。我在我的生日时既有快乐也有悲伤的情感。我为什么开心?我的朋友来和我庆祝。他们给我的生日礼物,有时礼物非常让我吃惊。同时,我能感觉到我的家人多么爱我,因为我的父母总是为我做一个生日蛋糕。他们不去买一个,而是自己做。我感到很高兴。然而,让我明白的是我的母亲遭受了最痛苦的事让我来到了这个世界。我感到抱歉为我的母亲她遭遇了什么。但是我答应她,当我有能力时，我会好好照顾她,。

The class teacher and we discussed the "food security". In todays society, human food safety has been a serious threat.

Now the children all like to eat snacks, and addicted to eat. Although parents tell them who is bad to the body, but they still continue to buy snacks, just have a fair into a "sneak". In the snack, the children to buy one of the most dangerous, is the spicy dry tofu.

Understanding on the Internet, I learned the spicy dry tofu is composed of metamorphic pork, plastic bags, such as some are unsafe, unhealthy materials again. Look at the pictures, some of the staff in the processing, should put the foot on the above, this is how not health! So I advise you not to eat spicy dry tofu also dont eat snacks again as far as possible.

There are a lot of people like to eat mutton string, and believe. It tastes very good taste, and there is a sheep shan wei, let people think this is the authentic lamb kebabs. Not actually, mutton string is called mutton string, but who can guarantee that the meat must be above mutton? Perhaps is pork, this is good. Some are made of rat meat, do you still eat like this? You might ask: "sheeps shan wei?" Shan wei is put "mutton string" sheep sheep urine bubble in some time, and then a wash, so the "delicious" clusters of mutton string was baked out. Here, dont I advised, I believe that you have not eat?

Now, can not eat meat, vegetables are dangerous, most of the vegetables are chemical pesticides, so you must be clean and wash the vegetables to eat, after all, it may do harm to your familys health.

Now, food safety not guaranteed, and peoples health is threatened, so making the uncles and aunts of food to ensure food safety, ensure peoples health.

这一节课老师与我们讨论了“食品安全”。在当今社会，人类的食品安全已受到了严重的威胁。

现在的孩子们都喜欢吃零食，而且吃上了瘾。尽管家长们告诉他们那些是对身体不好的，但他们还是一如既往的买零食，只不过有光明正大变成“偷偷摸摸”。在零食中，孩子们买的最危险的，就是辣条了。

在网上了解，我的得知辣条是由变质的猪肉，塑料袋等一些极不安全，又不健康的材料制作而成。看那些图片，有些工作人员在加工时，竟把脚放在了上面，这是多么不卫生啊!所以我劝大家不要再吃辣条了也尽量不要再吃零食了。

羊肉串，相信也有很多人喜欢吃。它吃起来口感很好，而且有一股羊膻味，让人们以为这就是正宗的羊肉串了。其实不是，羊肉串虽叫羊肉串，但是谁能保证上面的肉一定是羊肉呢?说不定是猪肉，这还算好的。有些竟是用老鼠肉做的，这样你还吃的下去吗?你可能会问：“羊膻味又是怎么来的呢?”羊膻味是把“羊肉串”放在羊尿里泡上一些时日，然后冲洗一下，这样一串串“香喷喷”的羊肉串就被烤出来了。说到这里，不用我劝，相信你就已经不会再吃了吧?

现在，肉不可以吃，蔬菜也有危险，大部分蔬菜都会打农药，所以大家洗蔬菜时一定要清洗干净再吃，毕竟它会危害家人的健康。

现在，食品安全得不到保证，人们的健康受到威胁，所以制作食品的叔叔阿姨们要保证食品的安全，保证人们的健康。

Hello,my name is jhon.My favorite animals are cat. Because they very cute. They can paly with me. They are my friden and they can gave me very happy. They are yellow , write and black. Many people all live them. I thing they are healhy. Can you tell me about your favorite animals?

Haze is mist floating a lot of smoke, dust and other particles and

formation of the turbidity phenomenon. January 29, according to the ministry of

remote sensing satellite monitoring: China has 130 square kilometers of regional

haze shrouded, serious pollution of air quality.

The fog haze weather how? Many families have a car, we have to travel more

convenient, but the car exhaust pollution of the air; Power plant, oil

refineries, chemical plants in our city "game", but the clock keep emit soot and

dust; The colorful fireworks let a person too many things to see, but air

ZhongYan WuTengTeng, become very cloudy, air quality has fallen sharply, PM2. 5,

PM10 index has soared, these are the main cause of fog, they bring us quick and

convenient and enjoyable at the same time, also quietly gave us the unintended

consequences.

Haze weather, our breathing is cloudy gas. The haze in the air can cause

diseases such as pneumonia, sore throat, bronchitis, heart, decline. In 1952,

the fog in London, England is like invisible killer, seized 4000 people in just

five days of life, after two months has killed 8000 people in the life, the

power of the fog, and this is a wake-up call for us.

We need the fresh air, is a healthy body. Please do not at the expense of

the health, and for the so-called good life. Driving less, green travel, a

variety of trees, protect forests. Haze, starts from me.

Human, science and nature, the three phase was quoted rates are inseparable. The wonders of nature, a little thing, through the baptism of the time, and meticulous observation, often can give a person with enlightenment.

Vast forests, sunshine give plants grace, to be able to get the nutrients and thrive. Such as the morning sun open the eyes of animals, everything is ready. Squirrels, squirrel, embarks from the house, looking for full sweet red pine nuts, all kinds of plant seeds and slowly by seeding them to other places. While the weasel feed on smaller herbivores, sable and then ate the weasel... As if people eat the big fish, big fish eat small fish, small fish eat shrimp, shrimp eat plankton, interlocking between RACES, interdependence restricts each other.

Foreign scientists have done an experiment: introduce the sheep in a rare nature reserve, where the bamiyan, natural environment is superior, and there is special personnel to the group of kids to their natural enemies, Wolf, moved to another place. So the sheep started in the breeding. Until grass and low shrubs are eaten, the number of sheep instead of less. Because they live too comfortable, there is no enemy attack, the number that is too carefree life let their constitution also fell. Then the scientists tried to introduce wolves again. The result is in the relationship between predator and prey, good robust species to survive, wolves eat sick defect part. Natural selection and evolution, has been the nature and even the survival of human society the same criteria.

Cut down some trees, is to destroy a part of birds and insects; Killing of bees, small fish, can also cause cannot spread pollen, fish cannot reproduce problem... Sabotaged a part of the food chain, will bring ill-defined disaster. Because in front of the natural fair, each species, each independent individual organisms is so beautiful and full of value.

Because of the diversity of species and colorful nature. Want to live in harmony with her and get the kind of treatment, will be good to nature, to understand the nature, and have good at discovering and innovative mind.

人类、科学、自然，这三者相生相息密不可分。大自然的奇妙之处在于：一件小小的事物，经过时间的洗礼以及细致入微的观察，往往能给人以启示。

广袤的森林中，阳光雨露给予植物恩泽，使其能够得到养料然后茁壮成长。等清晨的阳光掀开动物们的眼睛，一切也准备好了。松鼠、灰鼠从居所里出发，寻找饱满香甜的红松子，各种植物的种子于是慢慢的被他们带到其他的地方落地生根。而此时黄鼠狼以体型较小的草食动物为食，紫貂继而吃掉了黄鼠狼……就好像人吃大鱼，大鱼吃小鱼，小鱼吃虾米，虾米又吃浮游生物一样，各种族之间环环相扣，相互依存相互制约着。

外国的科学家曾做过一个实验：将一种稀有的羊引进自然保护区，那里水草丰美，自然环境优越，并且还有专门的人员为这群天之骄子将她们的天敌——狼，迁往另外的地方。于是羊群开始在此生息繁衍。直到草和低矮的灌木被吃光了，羊群的数量反而越来越少。原来是因为它们生活的太过安逸，没有天敌进犯，数量过于膨胀，太过悠闲的生活让它们的体质也下降了。后来科学家们尝试着再一次引进狼群。结果是在捕食者与猎物的关系中，健壮优良的品种得以存活，狼群则吃掉病弱残疾的部分。物竞天择，优胜劣汰，一直都是自然界乃至人类社会不变的生存准则。

砍掉了某种树林，就等于灭绝了一部分鸟类、昆虫;捕杀蜜蜂、幼小鱼类，也会造成花粉无法传播，鱼群无法繁衍的问题……大肆破坏生物链中的某一环，都会带来难以言说的灾难。因为在公平的自然面前，每个物种，每个独立的生物个体都是如此的美丽而富有价值。

大自然因为物种的多样性而五彩缤纷。想要与她和谐相处并得到其慈祥的对待，就要善待自然，了解自然，并拥有一刻善于发现与创新的心。
