高二英语作文:时间未必等于金钱

全文共 801 字

+ 加入清单

导语:有句老话是时间等于金钱。但时间真的一定等于金钱吗?以下是yuwenmi小编为大家整理的英语作文,欢迎阅读与借鉴,谢谢!

As a popular saying goes, Time is money. But does time definitely mean money? I dont think so. First of all, time is more precious than money. When money is spent, you can earn it back if you want to. However,when time is gone, it will never come back. To some extent, time is priceless. Second, not all time can be turned into money in the end. Some persons are idling all the time. Their time is just for wasting, not for earning money. They will end in nothing at last. So be sure to remember that time can be turned into money only with hard work involved in it.

【翻译】

时间未必等于金钱 有句老话是时间等于金钱。但时间真的一定等于金钱吗?未必。首先时间比金钱宝贵。金钱花完还可以再挣,而时间如果浪费了就一去不复返了。因此某种程度上,时间是无价的。其次,并不是所有的时间都能变为金钱。有些人整日游手好闲,他们的时间是用来浪费的,而不是用来挣钱的,最终将一无所得。因此务必要记住,只有努力工作,时间才能等于金钱。

Modern American famous entrepreneurs iacocca said: "without innovation, death." Is ah, this sentence is absolute. Innovation to the development of a person indeed played a very big effect, only learn to innovate, to learn from various angles, to make themselves permanently in the invincible position, to make it and get play on their original level, thus more effectively to change yourself. Rut is one of our well known idioms, which contains the truth is told us to learn to innovate. Once upon a time there were two men, a love to imitate celebrity calligraphy, and the other one is required to follow their own style to practice, another ultimately become a famous calligrapher, but the rut is still unknown. Thus, dares to innovate, to do something.

And what was said Mr Qi baishi is the portrayal of the story: "like I am dead, I dead." Go out of our predecessors framework, will not have their own heaven and earth. There is a story about a businessman and with partners go to gold, because gold prospectors, where resources are less, he learned to innovative ideas, to sell water, adapt to the needs of the market, and made a lot of money. These two examples all tell us the importance of innovation. Now the social everyone on the premise of innovation and to development, improvement, and change. How about, a person that has special mind, has innovation consciousness and the spirit of perseverance, he will be how the end of what? Of course is a perfect ending!

So, let us act, the academic society innovation, advocating innovation, to constantly improve themselves, while we its spring time, trying to do, is a person get give full play to the original level, make oneself permanently in the invincible position, let oneself have a perfect ending, for their own life added a brilliant color!

现代美国著名企业家艾柯卡说过:“不创新,就死亡。”是呀,这句话非常有绝对性。创新对一个人的发展的确起了很大的效果,只有学会创新,学会从多个角度,才能使自己永久地处于不败之地,使之并在自己原有水准上得到发挥,从而更高效地改变自我 。 墨守成规是我们众所皆知的一个成语,其中包含的道理就是告诉我们要学会创新。从前有俩个人,一个酷爱模仿名人书法,而另一个人则要求遵循自己的风格去练习,最终另一个成为一名著名的书法家,而那个墨守成规的人仍默默无闻。由此可见,敢于创新,才能有所作为。

而齐白石先生所说过的话正是这个故事的写照:“似我者死,学我者死。”走不出前人的框架,自己就不会有自己的天地。 还有一个故事讲述的是一个商人与同伙伴各自去淘金,由于淘金者数不胜数,哪儿资源又少,他学会创新思路,从而改卖水,适应了市场的需要,从而赚了许多钱。 这两个事例无一不告诉我们创新的重要性。如今,这个社会大家都以创新为前提,去不断发展,完善,改变。试问一下,一个人即拥有非凡头脑,又有创新意识和坚持不懈的精神,他会又怎什么样的结局呢?当然则是完美的结局咯!

所以,让我们行动起来,学会创新,提倡创新,去不断改善自我,趁我们其春年华,努力去做,是个人原有水准得到充分发挥,使自己永久性地处于不败之地,让自己拥有一个完美的结局,为自己的人生添上一笔绚丽的色彩!朋友,记住:创新改善自我。努力做吧!

香烟是危害人体健康的一位温柔的“杀手”,据媒体报道,吸烟的人容易得多种疾病,如肺炎、支气管炎、心血管疾病等等,吸一包香烟相当于减少1小时的生命。

我看过爸爸20多岁时的照片,那时的她白白胖胖,脸色红润。可不知什么时候起,爸爸每天都要吸一包烟。慢慢的,他的牙齿变黑了,手指变黄了,身上散发出一股难闻的烟味。我见了他,躲都来不及。我和妈妈几次劝爸爸戒烟,可他却说:“现在生活安定了,也该学着享受,再说,吸烟的男人有风度嘛!”虽说我们心里不高兴,但妈妈心软,最后还是由着她。

过了不久,我发现爸爸开始咳嗽,那声音越来越响了。先是轻轻的几声,然后是连续不断的咳嗽。有时咳得脸发红,连眼泪都流出来了。每天晚上,还没看见他回家,就可以听见他那刺耳的咳嗽声了,那声音听起来像七八十岁的老人一样苍老。爸爸实在熬不过,就只好求助医生。经过医生诊断,发现爸爸得了气管炎,这下,爸爸不得不下决心戒烟了。有时见爸爸实在忍不住了,我就把零食往他的嘴里塞,这个办法还真管用。

现在,爸爸长胖了,胃口开了,精神也饱满起来了。爸爸也主动把原来用来吸烟的钱补贴家用,有时也给我买学习用品、玩具,给妈妈购买衣服、营养品。现在,我的家里又充满了欢声笑语。

Cigarettes are endangering human health a gentle "killer", according to media reports, smokers prone to many diseases, such as pneumonia, bronchitis, cardiovascular disease, etc., 1 hour less smoke a pack of cigarettes is equivalent to life.

I saw the pictures of my father in his 20s when she was fat and red. I dont know when my father would smoke a pack of cigarettes every day. Slowly, his teeth blackened, his fingers turned yellow, and he smelled a bad smell. I saw him, and it was too late to hide. My mother and I advised my father to give up smoking a few times, but he said, "now that life is settled, we should learn to enjoy it. Besides, the man who smokes has grace!" Though we were not happy in our hearts, our mother was soft and finally let her alone.

After a while, I noticed that my father began to cough, which was getting louder and louder. First a few words, then a continuous cough. Sometimes his face turned red and his tears ran out. Every night, before he could see him go home, he could hear his shrill cough, which sounded as old as an old man in his 70s and 80s. Dad couldnt survive but he had to go to the doctor. After the doctors diagnosis, he was found to be suffering from bronchitis, and the father had to make up his mind to quit smoking. Sometimes I cant help seeing my father, but Im putting a snack in his mouth, and it works.

Now my father is fat, his appetite is open and his spirit is full. My father also offered to subsidize the money used for smoking. Sometimes he also bought me school supplies, toys, clothes and nutrition for my mother. Now my home is full of laughter.

Growth has given me endless happiness, but also bring many troubles to me from time to time: for growth, I with the feelings of a kind of desire, but somewhat bored.

The first: much homework. Though the teacher is decorated very little, but mother is three times of assignment, let me test the mountain every day. Go home at night, the first thing is to do my homework, then chew my everybody.

The second: less time. Can also play at school, at home, in addition to eat, when they dont have time to play the other time was spent on learning.

Third: friends less. Grow up, boys play with boys, girls like girls to play, if the boy and the girl talk, everyone else will be so good friends less, "enemy" had more.

Fourth: the demand is high. When I was a child, live carefree, free. Now, as the fifth grade students I have grown up, not as a child, do things to be careful, focused, after all, I have grown up. The carefree days are far...

Growth, although gave me a lot of trouble, but also bring me much happiness. At the same time, also because of the growing pains, I know a lot of, also aware of the many, many... Happiness and troubles can be compared them into a piece of a piece of paving stone, they are connect the leak, the road to success!

成长中,总有些挥之不去的烦恼。就如古人说的:“人有悲欢离合,月有阴晴圆缺。”人的一辈子为什么不会一帆风顺呢?我也不例外啊!成长给了我无穷的快乐,但也不时给我带来不少的烦恼:对于成长,我带着一种渴望的心情,但又有些厌烦。

第一:作业多了。虽然老师布置得很少,但妈妈却布置了3倍的作业,让我每天都啃书山。晚上回家,第一件事是做作业,接着就是啃我的书山了。

第二:时间少了。在学校里还可以玩,到了家,除了吃饭时就没时间玩了,其他时间都花在学习上。

第三:朋友少了。长大了,男生跟男生玩,女生就跟女生玩,要是男生跟女生玩就会被人议论,所以好朋友少了,“仇人”却多了。

第四:要求高了。当我还是小孩时,生活得无忧无虑,自由自在的。可现在,身为小学五年级学生的我已经长大了,不在是小孩了,做起事来要小心翼翼,思前想后,毕竟我已经长大了。无忧无虑的日子已经远了……

成长,虽然给了我不少烦恼,但也为我带来了不少快乐。同时,也因为这些成长的烦恼,令我懂得了许多,也意识到了许多许多……快乐与烦恼就可以把它们比喻成一块一块的铺路石,它们毫无漏缝的连接着,通向成功的路!

篇13:高二关于学习的英语作文

全文共 2679 字

+ 加入清单

Learning a foreign language is an enriching undertaking. To make the most of your experience, you may need to develop some specialized strategies. Here are some principles to keep in mind.

1. Language is more than a set of grammar rules. Although structural accuracy is an important component of communication, you must also learn how to communicate in a manner that is appropriate to the situation. Likewise, in addition to building a large vocabulary, you will also need to learn ways of paraphrasing so that you will be able to communicate effectively when you don’t know an expression or it has slipped your mind. Body language and gestures are also important communicative strategies.

2. Active language use is far more important than talking about language. The ability to recite the rules of English grammar does not guarantee that you will actually be able to communicate in the language. Spend your time communicating in the language, creating messages, obtaining information, listening for details and so on.

3. Don’t be afraid of making errors. Errors are a natural part of the language learning process and no one can avoid them. Do not let fear of making an error prevent you from communicating. Even if your language ability is not perfect, your message may be understood. Of course, accurate use of language is an appropriate goal of language study.

4. Language learning is a long-time process. Therefore you must have realistic expectations of your performance after one semester, one year, or several years of language learning. Advanced proficiency is often best achieved after long period of practice and residence in a country where the target language is spoken.

5. Be an active language learner. Study models, look for patterns, and make informed guesses, study idioms. If you do not entirely understand a passage, do not ask for a translation immediately. Make use of the language you already know or words that may be related to other words you know. Although language learning can be hard work, your efforts will be rewarded with a deeper understanding of yourself and the global village of which you are a citizen.

学习一门外语是一个丰富的任务。充分利用你的经验,你可能需要开发一些专门的策略。这里有一些原则要牢记。

1。语言不仅仅是一套语法规则。虽然结构精度是通信的一个重要组成部分,你还必须学会如何沟通的方式是适当的。同样,在构建大型词汇表之外,您还需要学习的方法套用,这样你将能够有效沟通当你不知道一个表达式或溜你的头脑。肢体语言和手势也很重要的交际策略。

2。积极的语言使用比谈论语言更为重要。背诵英语语法规则的能力并不能保证你会可以用语言交流。花费你的时间在语言交流,创建信息,获取信息,听细节等等。

3。不要害怕犯错误。错误是语言学习过程的一部分,没有人能避免他们。不要让害怕出错阻止你交流。即使你的语言能力并不完美,你的信息可能会被理解。当然,准确的使用语言是语言学习的一个适当的目标。

4。语言学习是一个长期的过程。因此你必须有现实的期望的性能在一个学期之后,一年或几年的语言学习。先进水平通常是最好的实现经过长期的实践和居住在中国,目标语言是口头的。

5。是一个积极的语言学习者。研究模型,寻找规律,作出明智的猜测,研究习语。如果你不完全理解一段,不要求立即翻译。利用语言的你已经知道或者单词,可能与其他单词你知道的。虽然语言学习是艰苦的工作,你的付出会得到回报,更深入地理解自己和地球村的公民。

烟里有一种对人身体不好的东西——尼古丁。

一枝香烟中的尼古丁可以毒死一只小白鼠,25g的香烟里的尼古丁可 毒死几头牛,40至60毫克纯尼古丁可以毒死一个人。

尼古丁的危害也是相当的大,它可以引起胃痛或其它胃病;还会使人引起心律不正诱发心脏病;严重的还可能引起癌症的爆发。

香烟是隐藏在我们身边的隐形杀手,是大家所应警惕的。

据科学家测定,烟草中含有数百种复杂的化学成分,大部分对人体有害,其中焦油、尼古丁、酚类、醇类、酸类、醛类等40种是有毒和有致癌作用的物质。烟在点燃后,所产生的烟雾,包含了烟草中所有的化学成分,同时比烟草本身又增加了一些有害物质,如一氧化碳和烟焦油等。这是因为除烟草本身外,在制成卷烟的过程中,要在原料中加入一些可可、甘草、糖、甘油、乙二醇等调味、湿润、产香、助燃物质。这些添加剂虽然本身无害,但在燃烧过程中却起了变化。例如,在鼠背涂上可可燃烧后产生的烟油,可长出皮肤瘤。甘草中的甘草酸在燃烧后,与其他成分化合,可生成有致癌作用的多环芳烃。糖与烟草一起燃烧后增加了焦油量,而糖燃烧后的产物是烟中的一个重要致癌物。甘油和乙二醇在燃烧后的物质,不但可能使吸烟者患膀胱癌,而且所产生的丙烯醛可抑制气管和纤毛分泌物从肺内排出,从而增加患气管炎和肺气肿的机会,并使患有这两种病的人病情加重。

烟对人的危害是多么大啊!所以我们不能吸烟。杜绝吸烟,造福后人。

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……’’

虽然我因为看书误了事,但我仍然爱读书.因为从书中,我学会了许多知识,悟出了许多道理,认识许多朋友:丑小鸭、快乐王子、孙悟空、鲁迅、冰心、爱迪生……读书还使我的作文水平提高了不少呢!

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!

污染环境英语作文应该要如何写呢?以下便是小编为大家整理的污染环境的英语作文范文,希望能给大家带来帮助。

污染环境的英语作文【1】

I read a piece of news recently. It says that in Japan marly businessmen ave selling fresh air to customers.and now it is becoming more and more popular. Why?——Fresh air is getting less and less in Japan, and so is it in the U. S. A.

In fact, environmental pollution is a very serious problem the whole world is facing.

it is mainly caused by the waste products released from artificial substances, industrial production and increased consumption of goods. Bedsides, the use of chemical substances in agriculture also causes environmental pollution. Look at the sky, you can see that dense smoke is being released from the high and big chimneys; those dirty and poisonous substances are flowing into the rivers that we use for drinking water and millions of tons of waste products are heaping around us.

How to change this condition?More and more countries are trying to work out some effective means to bring it under control, but no great success has been made.

污染环境的英语作文【2】

The picture shows the pollution caused by chimneys of the factories in cities. Often, the sky is covered by large clouds of smoke from chimneys. The air is nearly suffocating, especially in the evening as it becomes cold and the smoke is spreading everywhere. The scene reminds us of the end of the world.

From the picture we can infer that the drawer of the picture intends to convey to the readers that unplanned factories has brought about great hazards to the city air condition. Due to planning mistakes, factories were usually placed in the center of cities, among residential and business districts. Besides, nearly every block has several chimneys for the heating system, which makes the whole city immersed in thick columns of smoke. As a result, respiratory diseases have been reported to be rising and old people dying of the worsening air pollution.

Pollution is really a hot issue in the world. If we don’t take useful measures, we may live in terrible surroundings, and some unexpected results may come out in the end. So, what we should do is to bring down the problems caused by chimneys. For one thing, factories with chimneys should be moved out of the center of the city and it should be made sure that the waste gases are at least not poisonous. For another, other means of heating should be developed to stop using coal. In a word, in the city there should be no coal, no chimney, and no smoke to pollute the air.

污染环境的英语作文【3】

It is reported that ten big cities in China are being ranked among the top twenty cities with the highest pollution index in the world. This means it is high time we did something to bring the situation under control.

Many factors are contributing to the deteriorating situation: industrial wastes pumped into the air, the lakes and rivers; a increasing number of automobiles crowding into the streets; the widespread use of plastic bags etc.

To my view, stiffer laws and regulations must be implemented to check pollution. Industries that release wastes without permission should be heavily fined. Cars should be equipped to minimize the exhaust they release into the air. And the use of plastic bags and disposable meal boxes should be banned. What’s more, the media should play an important role in implanting a sense of environmental consciousness into people’s mind.

If everybody works toward a common goal of making the environment better, we can create a cleaner and lovelier world for us and for the coming generation.
