Nowadays, many female students are idolaters. In order to chase after their

idols, they always do extreme ways. For example, they listen to their idols

songs almost every minute in their daily life. With a smart phone, they do it

when reading books, doing homework, having meals, and even walking on the road,

which may have many bad effects on their health and even cause safety problems.

Besides, plenty of girls think they like their idols so much that they chase

after their idols wherever they go, just to get their signatures. They also

daydream of dating with their idols and get psychological problems at last. All

of these are worth our attention. We should educate girls that their idols are

some people who are lucky enough to be famous, and listening to their songs and

watching their photos are the things they should do in their life. Thus, they

are supposed to balance chasing after idols and their daily life properly.

人的爱好多种多样,有新奇绝妙的,有平淡无奇。我的爱好虽不新奇,但广泛得连父母都时常感叹。而在这众多的爱好之中,我还是对读书情有独钟。

爱看书还得从七年前说起。那是贪玩的我并不怎么爱看书,但有一次,从玩具堆中发现了一本被翻开的书。好奇心促使我看了下去。一下子,我马上被书中那精美的插图与那精彩的内容给吸引了。而且一发不可收拾,从此,我就爱上了读书。

长大后,懂事的我越来越爱看书了,每天都要看,少看一天都不行,成了一个不折不扣的“小书虫″。为此,我还闹出了笑话呢!记得有一次,妈妈让我烧水,烧水时,我便拿起一本书,津津有味地品读书中的精彩内容,看得忘乎所以。结果,水壶被烧坏了,搞得满屋子烟。这时,妈妈看见了,就问我怎么回事。我这时才回过神来。“糟糕!我的水呢?”妈妈见我这副模样,无可奈何地唉声叹气:唉!你这个小书虫!我提醒过你多少次了……’’

现在,书成了我每天必需的营养品,生活中没有书,就好像鸟儿没有翅膀,生命没有书,就好像生活没有阳光,书是人类进步的阶梯,书是知识的源泉!

我爱读书,因为读书使我的生活丰富多彩,使我的生命充满阳光!

Miles "haze" fell to the general public had panic, mom always said to me, the air pollution is too serious, cant go out.

But, I think, this is not the ultimate, government departments should fundamentally to solve the related problem.

近期,天气总是蒙蒙的,我想出门玩耍的愿望总是被这鬼天气给搅和了。通过阅读报纸,我明白了这种天气就是雾霾,它是因为空气遭受比较严重的污染才在一定的条件下形成的。看来,我们身边的空气质量真令人堪忧哇。

前两天降过一场雪,大家对这次降雪充满期待,以为雪后雾霾就会消散。然而雪后雾霾依在,不少地方的空气质量更差了。报纸频频报道这种恶劣天气产生的原因带来的影响,让我也对雾霾的关注度日益提高。

针对持续的雾霾天气,各地出台不少措施来改善空气质量,如限制车辆出行,淘汰老旧车辆,以气代油等等。可是,我想,这还不是根本,政府部门应该从根本上着手解决相关问题。

净化空气,改善环境,刻不容缓!让我们大家都行动起来,还世界一片洁净!

篇6:高二英语作文TheOpinionofBuyingCars

全文共 999 字

+ 加入清单

Nowadays, we can often hear the discussion whether buying cars should be encouraged. Some people suggest that we should buy cars. But others claim that driving cars is not a wise idea. As far as I am concerned, I am in favor of the latter opinion.

To begin with, there are few parking lots, so the streets are made narrower by the cars parked along the roads. For example, my father could not find any places to park when we went to the supermarket.

Moreover, many drivers do not obey regulations, because people do not pay enough attention to the rule of traffic. For instance, I often see people cross the road when the traffic lights are still red.

Last but not least, the growth of new roads’ construction is usually slower than the increasing number of cars. For example, the length of the road has gone up by 20% in 2002. However, the number of cars increased by 50% in the meantime.

From what has been discussed above, we could draw a conclusion that encouraging buying cars is not fit for today.

Environmental problems are becoming more and more serious all over the

world. For example, cars have made the air unhealthy for people to breathe and

poisonous gas is given off by factories. Trees on the hills have been cut down

and waste water is being poured continuously into rivers.Furthermore, wherever

we go today, we can find rubbish carelessly disposed. Pollution is, in fact,

threatening our existence.

The earth is our home and we have the duty to take care of it for ourselves

and for our later generations. Fortunately, more and more people have realized

these problems. Measures have been taken to cope with these problems by the

government. Laws have been passed to stop pollution. I hope the problem will be

solved in the near future and our home will become better and

better.Environmental problems are becoming more and more serious all over the

world. With the development of industry and agriculture, cars make GREat noises

and give off poisonous gas. Trees on the hills have been cut down,and waste

water is being poured continuously into rivers. Furthermore,wherever we go

today, we can find rubbish carelessly disposed. The whole ecological balance of

the earth is changing. Massive destruction of environment has brought about

negative effects and even poses a great threat to mans existence.

We must face the situation that exists and take actions to solve our

environmental problems. For instance, new laws must be passed to place strict

control over industrial pollution, the pub!ic must receive the education about

the hazard of pollution and so on. We hope that all these measures will be

effective and bring back a healthful environment.

篇11:高二英语作文:照顾老人

全文共 1590 字

导语:尊敬老人一直是中华民族的传统美德,我们要多多照顾他们,下面是yuwenmi小编为大家整理的优秀英语作文,欢迎阅读与借鉴,谢谢!

In the picture, an old man is sitting in the wheelchair, and a dog is serving him with milk and food. Ironically, it is the dog that takes the responsibility to attend the old man. We cannot help wondering where the old man’s grown up children are. It is they not the dog who should take good care of their old father.

The implied meaning of the picture is really provoking. It is quite true that in our society there are some grown-up children who treat their old parents badly. When their old parents are too old to take care of themselves, they often view them as a “burden” of their family life. They refuse either to support their aging parents financially or to look after them. No doubt, this immoral behavior of these grown-up children’s should be subject to social condemnation.

To respect the old has long been a traditional virtue of the Chinese people. We should always bear in mind that we are much indebted to our parents in that they not only gave us life but have done much to bringing us up. It is against conscience to escape from the responsibility to take care of our parents. Rather, we should pay back for the love and care of our parents by making their later years happy and enjoyable.

【参考译文】

在这幅画中,有一位老人坐在轮椅上, 一只狗正在给他送牛奶和食物。具有讽刺意义的是,是狗在承担待候老人的责职。我们不禁要发问老人的成年子女在哪里?好好照顾年迈的父亲应该是他们而不是狗。

这幅画的寓意真是发人深省。确实,在我们的社会里有些成年子女不能善待老父母。当老父年迈不能照顾自己时,他们经常把父母看作家庭生活的负担,不愿在经济上赡养或生活上照料老人。毫无疑问,成年子女这种不道德的行为应受到社会的谴责。

尊敬老人一直是中华民族的传统美德。我们应该永远牢记:我们应该对父母感恩,因为父母不仅给了我们生命,而且为抚育我们长大为我们付出了太多太多。逃避照顾的责任父母是违背良心的。我们应该让他们晚年生活快乐,回报他们对我们的关爱。

I always think there is not enough time. For example, I have just taken a

three-day holiday. But when I look back, I just feel that it‘s only one day.

There goes a proverb, “Time is money”。 Now I want to say, time is more precious

than money, because when money is spent, we can earn some more again. However,

when time is gone or lost, never will it return.

Time goes without being noticed. The time for our study and work is usually

limited. So I think we must make full use of our time. But it‘s a pity that I am

always not aware of the importance of time until it’s too late.

So I think, I should get into the good habit of saving time because wasting

time is equal to wasting one‘s life. Do not put off what can be done today till

We were so happy and the trip was just perfect. In the rest of my holiday, I did not do anything even related to study. Everything is all about games. However, I will not have a chance to spend my summer holiday like the last one. There is much more homework that I have to use probably three quarters of my holiday to finish it. If there is not so much homework, I might have my ideal summer holiday in this year. My ideal holiday is that go to the beaches in México with my family. For about a whole month we can completely relax in the beautiful beach. In the morning, after the delicious México style breakfast, we can walk along the beach while enjoy the beautiful morning sunshine. In the afternoon, we can have the freshest seafood for lunch. After lunch, take a nap in the sunshade would be the best thing to do. At dusk, there is the most gorgeous sunset on the sea... I love the beach, I love summer holiday.

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。
