我的家乡英语作文高二经典20篇

暑假里，我看了一本有趣的童话故事书。

During the summer vacation, I read an interesting book of fairy tales.

我喜欢看这本书，因为这是我看过的童话书中最好看的一本书，我反复看了三、四遍，我对这本书是爱不释手。

I like to read this book, because it is the best I have seen the book of fairy tales in the book, I read it three or four times, I was one of this book.

这本书大概描写的是：有四个孩子无意中进入了一个衣橱，来到了一个叫“那尼亚”的地方，那里由一个女巫统治着，女巫把“那尼亚”变成了冬天。孩子们和一头狮子打败了女巫，春天回来了，孩子们也当上了国外和女王。许多年后，孩子们都长大了，他们追捕一头仙鹿时，无意中回到了衣橱里。

This book is about it: there are four children inadvertently entered a wardrobe, and came to a place called "Narnia", where a witch to witch ruled, "Narnia" into winter. The children and the lion beat the witch, spring is coming, the children also became a foreign queen. Many years later, the children have grown up, they pursue a fairy deer, inadvertently back in the closet.

我看完这本书后，想到了另一个结尾，我觉得这个结尾更适合这本书，就是：至今，衣橱还在那个人家里，你不信就去看看吧!

I read this book, the thought of another end, I think this is more suitable for the end of the book, is still in the closet:, family, you do not believe it to have a look!

正如郁达夫所说：秋天，无论什么地方总是好的。但各处的秋总有不同，我觉得故乡的秋有钢。有柔，钢的猛来暴雨，柔的尽撒温阳。所以我独爱家乡的秋。

呼呼……几阵狂风刮起，刮得黄叶直溜打滚，那是东角唯存的几粒秋叶，咋把它刮掉了呢，可谓秋风无情啊。

雨也赶来了，东一滴，西一滴，大如豆粒。

“大伯，快来遮遮雨吧。”大伯牵着牛跑得很快“不了，不晓得这雨要下到何时呢。”是啊，刚才还很晴朗的，突地又下起雨来。这不知一下便是两天。三天呢。不时还来两个闷雷。真叫个猛啊。

山上路上水哗哗的淌，咳，整天的困在屋里，不时觉得心头烦躁，它还在下，而且很努力。

不过，下起雨，整天忙碌的人们落得过清闲，只翘着脚，悠哉悠哉。

但雨停后又会出现夕阳，这时村里的老人乐意出来散散步，看看这被净水洗过的一切，生机如初夕阳从山头撒过一丝丝光线照在身子上感到一股股暖意，真可谓夕阳无限好啊。或是到村边鱼塘钓钓鱼。静静的端坐在石头上，凝视着一颗弯弯的鱼竿，盼望着，期待着——它是希望。

“啊，雨停了，在上山犁几划地去。”

Welcome to my hometown!  Haimen is my hometown. It is a modern and busy town. It has a long history. There are many big supermarkets, beautiful gardens and good factories here. It is very easy to go shopping. You can see green hills, big trees and nice flowers. There are many restaurants in Haimen. You can enjoy Haimen goat. It tastes very delicious. Many visitors come here to enjoy it.

There are many good places to visit. There is a park and a big Shopping Mall. You can see films in Renmin Theatre.

My school is one of the best schools in my hometown. It is on Changjiang Road. It is very beautiful. I hope you can come and visit soon.

The first day for me to go to high school, I felt so excited, because I

came into the new stage of my life. The school asked the students to live in the

dormitory, so I had to move out and left my parents. This was such a big

challenge for me, because I never left home before. I needed to learn to be

independent, what’s more, I also learned to get along with others. High school

was like a little society for me and I handed the problems well. The other

challenge was from study. I had to learn so many subjects and fought for my

future college. I met difficulties and felt frustrated, but I told myself not to

give up and I got over the difficulties. High school life is not easy, but we

grow up quickly.

In China, there is a saying that the children who live in the countryside areEarly-maturing, it is not about the physiology, it is about the mentality. The reason for the children being premature is various. Some children live in an unhappy family, such their parents get divorced or their parents don’t get along with each other. Living in such a family, the children will not grow up in a normal way, they will have sad feelings and become to know more about the unlucky things. Some children who live in the country need to take more responsibility, because their parents work in the big cities, so the children have to take care of themselves and also learn to do the house work. It is not good for the children to be early-maturing, they should grow up step by step, the parents need to give more care on the kids.

在中国，有一句话，农村的孩子早当家，这不是说生理上的，而是说心里上的。造成孩子早熟的原因有很多。一些孩子生活在不幸福的家庭，比如他们的父母离婚或者他们的父母相处不好。生活在这样的家庭，孩子不会正常的长大，他们会感到悲伤，了解更多不幸的事情。一些住在农村的孩子需要承担更多的责任，因为他们的父母在大城市打工，所以孩子需要照顾自己，也要学着去做家务。孩子早熟是不好的，他们应该一步一步地成长，家长需要给予孩子更多的关爱。

Its about one and a half month away from the Chinese New Year, It is a

festival celebrated by the Chinese people at the beginning of the lunar calendar

year.

As of the Chinese traditional customs, our parents and grandparents will

sweep every corner of the house and clean the windows until they gleam, and

washing clothes, buying foods and goods for the new years future use and

presents.

Children will be the most benefited group during this feast period. One

month before that, they are expecting the new clothes, delicious foods. The

firecrackers and the years allowance for their increased ages.

In recent years, with the rising of the standard of life, Chinese tend to

make various holiday plans to spend a different and meaningful new year. Such as

traveling abroad, or be absorbed in their hobbies, and even work.

Why today we try to spend our Chinese new year in such a different way? I

think thats because this is a era of free life and personality high-ranking.

Though there are still something traditional, our young generation is attempting

to make something new and suitable for ourselves. And we would like to take

something really worth to be cherished in our memorable treasures. Thats

amazing and wonderful!

Ill always keep in mind that the Chinese new year is a great feast

inherited from our ancestors, but if necessary, I would like to enjoy it by some

ways personal.

Some days ago,it was the Chinese Spring Festival.So I went to shopping with

my parents.the old saying said that to go to outside to have a walk in the new

year,you could get the good luck within this whole year.it always a happy

festival in our country,and the folk in the departments were very happiness. it

was very crowded.we went to the downtown to buy some presents for our

relatives,of course,i got a big present from my parents.it was a thing that i

wanted to get for a long time.you know,it was the festival,so all the

departments were saled their products in a low price. its cheap for us.all the

things you saw were perfect.i was very happy that i could go to shopping with my

parents. because i could get the present,and the most important reason is i

could go with my parents.

The Dangers of the Fake Product

“Shan Zhai” is the new words to express fake products, people use it to express the highly imitated products, some manufacturers produce the Shan Zhai products to make great profit, but it is so unfair to the customers, they pay so much money in the purpose of buying the genius stuff instead of the fake products. Fake products not only cheats people’s money, but also brings people dangers. Such as the medicine, if people buy the fake one, once they eat it, they will feel uncomfortable and get the illness, the most terrible situation is that they will kill themselves. Fake product is so harmful, though the government has taken some action to ban it, still people sold it, it is the temptation of profit that makes people sold it. What if their relatives have bought the products, so in order to keep people healthy, fake products should be banned.

“山寨”是用来表达伪劣产品的新代言词，人们使用它来表达高仿产品，一些生产商生产山寨产品以此来获取巨大的利润，但是这对于顾客来讲是不公平的，他们花费了这么多的钱，只为了买到真的产品而不是假的产品。伪劣产品不仅欺骗了人们的钱，而且给人们带来了危害。比如药，如果人们买到伪劣的，一旦服用，就会感到不舒服，生病，最严重的情形就是因此失去生命。伪劣产品是如此的有害，虽然政府已经采取了一些措施来禁止售卖，但是仍然有人兜售，他们是抵挡不住金钱的诱惑。如果他们的亲戚买了这些产品，会怎样呢，因此为了人们的健康，不要再卖伪劣产品了。

Nowadays,

with the development of computer, the function of computer has developed,

too. We can use computer to check the instant news, make friend and so on. The

reason why so many people addict to computer is that they like to play the

computer games, there are all kinds of computer games, everyone can find a game

which is suitable to him. Too much involve in the computer games is wasting

time, we should control our habit. First, we must set the limit time on it, wed

better not to play the game over an hour. We have to tell ourselves that we must

stop playing when the time is up, we have another thing to do. Second, we should

go out with friends often, so we can communicate with others, it makes our mind

not focus on the computer games. I am not saying we should not play computer

games, but we should not addict to it.

"Ah! My hometown has changed! "I cried with joy.

The change in my hometown is really big in these years! It used to be dirty and smelly, and there was a lot of junk in it. There were no trees on the hillside, only one tree stump. Around us there are some factory chimneys discharge smoke, gas, disorderly discharge, even lead to the surrounding trees, flowers and plants, all become withered yellow, often stink in the river, some fish died, rarely see the figure of a bird. Because of the bad environment, the air is seriously polluted and people often get sick.

With the improvement of peoples living standards, the awareness of the environment has improved greatly. Now people no longer throw garbage, factory construction also becomes a green plant, factory around trees and flowers in full bloom, the air becomes pure and fresh, the river water becomes clear gone, the water is very little fishes. Every year on March 12, people will plant trees with shovels and saplings, and now the trees are thick and the birds often sing on the branches. The environment is better, and peoples mood is better and healthier.

The changes in my hometown made me love my hometown more and helped me to study harder and work harder for a better home.

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。

Dear Tom,

I`m happy to share my opinion about hometown，shijiazhuang. Today,shijiazhuang is quite different from ten years ago.In the past,there was a little road in the city,and the road was very narrwo.As there is the capital city of Hebei Province,the traffic was very heavy.But there have built a lot of roads in these years,and all of these are broad.

There were only 3 parks in the city at ten years ago,and the air pollution was very serious.However,there are a great many of new parks were built.People often go to the nearest park do morning excise,and children also enjoy there.Of course,the air also improved a lot.

Today`s shijiazhuang is a beauty and modern city ,welcome to my hometown with your family.

I grew up in a small village. I am the second child of the family, and my sister is the eldest. Our house is on the main street of the village so I always saw a lot of people on the streets There were farmers, fishermen, and a few merchants in the village. My sister and I used to play with the next-door children; their father is an elementary school teacher. Sometimes when we played together in the house we made so much noise that my mother wanted us to play outside, so we went to the seashore to look for crabs and clams, and pretty seashells, too. Also, we enjoyed running on the beach chasing each other. On breezy days we used to enjoy flying kites on the beach. When I look back on my early life in the village, I feel I had a happy childhood.

我在一个小村庄里长大。我的第二个孩子的家庭，和我的姐姐是老大。我们的房子是在村里的大街，所以我总是看到很多人在街上有农民，渔民，和村里几个商人。我的妹妹和我经常玩邻家的孩子;他们的父亲是小学教师。有时，当我们发挥我们在房子里做了这么多的噪音，我的母亲希望我们在外面玩，所以我们去海边寻找螃蟹和蛤蜊，和美丽的贝壳，太。同时，我们喜欢跑在沙滩上互相追逐。在起风的日子里，我们喜欢在海滩上放风筝。当我回头看我的早期生活在村里，我觉得我有一个快乐的童年。

dear eric,

it’s very kind of you to write me and let me know about your beautiful city. now i’d like to tell you something about my hometown quanzhou.

the city stands on the west bank of the taiwan straight. it is a beautiful place for people to live in. its economy has been developing rapidly in the past ten years. new factories, houses, roads and bridges have been built. more schools and hospitals are available for its people. however, there are still some problems, such as water, air and noise pollution and heavy traffic in rush hours. in my opinion, quanzhou should develop its economy scientifically. i would also think that the growth of its housing construction should be brought under control so that we’ll have a better hometown in future.

yours,

lihua

With big eyes， there is an emergency ears like flying up to now。 You guess what？ Let me guess， is the rabbit。

A rabbits eyes like ruby， of course， I also gave a name to my rabbit called ruby。 Because the rabbit eyes glistened like ruby。

Remember once， my mother took me to go for a walk， I bring my ruby went to the park。 Ruby remembered it home for many years， because of the ruby grew up in the park， but his mom and dad have vanished into thin air， I also know that the rabbit is very poor， but I also didnt find its relatives。 The rabbit ears soon ran off， may be sad， I had to chase her for a long time。

This is my favorite little animals。 Smart， lovely ruby。

眼睛大大的，有紧急情况耳朵像飞的一样竖起来了。大家猜猜是什么？猜不到吧，就是兔子。

兔子的眼睛像红宝石一样，当然，我也给我的兔子起了一个名字叫红宝石。因为兔子的眼睛像红宝石一样亮晶晶的。

记得有一次，妈妈带我去散步，我带着我的红宝石来到了公园。红宝石想起了它多年的家，由于红宝石是在公园里长大的，但是他的爸爸妈妈却消失得无影无踪，我也知道兔子很可怜，但是我也没有找到它的亲人。兔子很快就竖起耳朵跑了起来，可能是伤心了，我追了很久才追到。

这就是我最喜欢的小动物。聪明、可爱的红宝石。

I’m an outgoing girl and my name is Shi Yun. I love singing songs,

especially pop songs. My favorite singer is Jay Chou.

As we all know, Jay is a superstar of Asia. He has excellent music skills.

He started to play the piano at 5 years old and studied hard. When he was 15

years old, he was able to write songs. But the environment in which he lived is

not very good. When he was a child, his parents were divorced and as a result

his childhood was full of depression. He lived with his grandparents. He was

always silent and didn’t like talking to others. At the age of 16, he was

attracted by the bass’s low voice. So his mother bought one for him and he

started to play the bass. His success is filled with tears and sweat.

From his story, I know if I want to be successful, I should work harder. I

want to go in for music, although I know the way to success is very difficult

for me. Now that I choose this way, I’ll do my best to realize my dream. Of

course I will tell myself I will be a superstar someday.

My hometown is famous Flower City. Because home roadsides, school yard and could see the figure of sweet-scented osmanthus tree, so called the Flower City.

In a flash, the golden autumn came. This is the sweet-scented osmanthus Hanbaoyufang season, the city of sweet-scented osmanthus are open. I walk in the street, smell the refreshing fragrance, can not help but come to a tree, looking at the long hiding in a green and leafy in the sweet-scented osmanthus that, ah! So beautiful, why Yao Guihua never dazzle own beautiful? I can not help but observe off a sweet-scented osmanthus, but I still do not understand why.

I sat on the ground, I looked at the floor of the sweet-scented osmanthus, ah! I really like sprinkle a layer of snow. This charming sweet-scented osmanthus fragrance really beautiful!

I love the sweet-scented osmanthus, more love Flower City!

My hometown Shao Dong, is a land of fish and rice, orange township, there is also a prosperous city. Although Shao Dong is not big, but I love Shao Dong.

I love the hometown of reservoir. On one occasion, we went to the cave to play, passing a reservoir, the endless blue waves with the water, to break out. Green mountains with clear water. Waterfowl like received an invitation from nature, hurried to the reservoir above the dancing, just like a beautiful landscape painting.

I love the hometown of the field. The late autumn season, casing of orange trees, small lanterns hung, approached a look, this is where the lantern, was shimmering oranges! In the whole stream, small groups of fish in the play, grass carp as reserved gentleman, easygoing to swim in deep water; Carp like naughty children, the high jump. Rice in the field waves rolling, during the day, people in the field cultivation; In the evening, people with a fishing rod leisurely sitting on the river.

I love my hometown city. At a young age, the city is full of garbage, sunny day is grey, rainy day is mud, really let a person feel sick. Now, wide cement road convenient; These skyscrapers, can take the lift to the top; Busy pedestrian street in the supermarket and lively, everywhere surging crowd; Center of the park under the big tree, there are rows of the bench to rest to the person, there are many small bench next to fitness equipment; And one small unit of the courtyard, the yard has a garden, pavilions, white wall, the wall covered with ivy and grasses, herbs, or feel more tender in accordance with the people.

Shao Dong is my beautiful hometown, I love my hometown Shao Dong.

我的家乡邵东，是鱼米之乡、蜜桔之乡，也有繁华的城市。虽然邵东不大，但我爱邵东。

我爱家乡的水库。有一次，我们去岩洞玩，路过一个水库，一望无际的水面泛着碧蓝的波涛，此起彼伏。青青的山护着清清的水。水鸟们像是接到了大自然的邀请，匆匆赶到水库上方跳起舞来，真像一幅美丽的山水画。

我爱家乡的田野。深秋时节，满园的桔树上，挂着一个个小灯笼，走近一看，这哪里是灯笼，明明是闪闪发光的蜜桔呀!在一条条小河里，三五成群的鱼儿在嬉戏，草鱼像矜持的绅士，逍遥自在地在深水里游着;鲤鱼像淘气的孩子，比赛跳高。白天，田野里稻浪滚滚，人们在庄稼地里耕作;傍晚，人们拿着鱼竿坐在河边悠然自得地钓鱼。

我爱家乡的城市。幼时，城里到处都是垃圾，晴天是灰，雨天是泥，真让人难受。现在，宽阔的水泥路四通八达;一栋栋高楼大厦拔地而起，可以坐电梯到顶层;繁华的步行街和热闹的超市里，到处可见涌动的人群;中心游乐园的大树下，有一排排给人休息的长椅，长椅旁边有许多小巧的健身器材;而一个个小小的单位庭院，院子里都有花坛、亭台、粉墙，墙上爬满了爬山虎和野草闲花，更觉娇嫩依人。

邵东是我美丽的家乡，我爱家乡邵东。

Another haze weather, the visibility to hundreds of meters. Both vehicles and pedestrians in feeling, without laughing, also do not have the bird, in such an environment, there are only pungent odor, and dark.

Fog, originally like smoke, such as gauze, like a gauze over the earth. How many men of letters through the ages, it has to, to dump. Now with this beautiful fog fog seems to have a relationship, and made what mistake?

Fog haze, seemingly "blood relationship" with the fog, but it is very different and fog. The mist, is floating in the air water vapor condensation of water droplets or ice crystals. Sometimes fog forecast sunny, sometimes the forecast of rain, fog appears to be chaotic, but as long as to master the characteristics of radiation fog, advection fog, observation, careful analysis, can accurately grasp the fog and sunny, rainy, in order to predict the weather. For the agriculture, transportation, aerospace, navigation is useful. And haze is different, it is made of the dust in the air, sulfuric acid, nitric acid, and organic hydrocarbon particles composed of gray.

又是一个雾霾天气，能见度不足以百米。无论是车辆还是行人都在摸索前行，没有了嬉笑，也无了鸟鸣，在这样的环境里，有的只是刺鼻的气味和满目的昏暗。

雾，原本似轻烟，如薄纱，似纱巾笼罩着大地。古往今来，它曾让多少文人墨客为之陶醉，为之倾倒。而今与这美丽的雾貌似有着一丝关系的雾霾，又犯下了什么滔天大罪?

雾霾，看似与雾有“血缘关系”，但它却和雾截然不同。雾，是由浮游在空中的小水滴或冰晶组成的水汽凝结物。有时雾出预报晴，有时雾出预报雨，似乎混乱不堪，但是只要掌握了辐射雾、平流雾的特征，多方观察，仔细分析，就能准确地抓住雾与天晴、落雨的规律，以便预测天气。这对于农业、交通、航天、航海都有用处。 而雾霾就不一样了，它是由空气中的灰尘、硫酸、硝酸、有机碳氢化合物等粒子所组成的小灰粒。
