篇5:关于道德的高中英语作文
全文共 1567 字
+ 加入清单China has long been known as “the land of ceremony and propriety.” Today however people often complain that public morals are no longer what they used to be. A family for example likes a cell of society which also mirrors the general mood of a country. As we know the Chinese have very strong family ties. But with the emergence of a “modern” concept to families people find that problems like high divorce rate and extramarital affairs become more serious than ever before.
Another example: the name of Lei Feng who was always ready to lend a helping hand to others used to be known by almost all Chinese as a model to learn from. But today some people claim that “the spirit of Lei Feng” is outdated. Fashionable ideas say money talks. In the early stage of the market economic development the appearance of some evil phenomena is not surprising. But we should not sit passively by and let it run rampant. Instead active measures should be taken to improve morals and ethics of the public.
Personally the media should play a leading role in this regard. They should spare no effort to praise the good and criticize the evil. They should guide people how to tell the truth goodness and beauty from the fault ugliness and evil.中国素有“礼仪之邦”的今天,然而,人们经常抱怨公共道德也不再是过去的样子了。一个家庭,例如,喜欢一个社会的细胞,这也反映了一个国家的一般情绪。正如我们所知道的,中国人有很强的家庭关系。但随着家庭的“现代”概念的出现,人们发现问题的高离婚率和婚外情变得比以往更为严重。
另一个例子:雷锋的名字总是愿意伸出援助之手给别人,被称为几乎所有的中国人作为一个模型来学习。但今天,有人声称“雷锋精神”已经过时了。时髦的想法说钱谈判。在市场经济发展的初期,一些恶现象的出现并不令人惊讶。但我们不应该被动地坐着,让它横行。相反,应采取积极的措施来改善公众的道德和道德。
就个人而言,媒体应该在这方面发挥主导作用。他们应该不遗余力地赞美善和批判邪恶。他们应该引导人们如何从错误、丑陋和邪恶中讲真话、善和美。

while fear of death is universal, my worry about death is so overwhelming that there is not a moment passing without my thinking of it. i never bring this up with any other, just because no one will ever realize the seriousness of this problem. i know it very clearly that as long as there is life, there will be death. in addition, though i am still so far away from death, i have been plagued by the thought of it for years. fortunately, the root of my fear of death lies in my overzealous love for life. i am too timid to think of the end of life, when every worldly affair should be thrown away. how can i carry on without friendship, affection, and joy of being alive? i really hate to leave all these behind. to ease my worry about death, i should make the fullest use of this life i now possess. concentration on this life can at least temporally make me forget about death. as a matter of fact, i really don't need to worry so much about death, for i already have too much to worry about this life.

+ 加入清单温室里的花朵永远都是最脆弱的,学会独立是很重要的。下面是小编为你整理的关于独立的高中英语作文,希望你喜欢! 关于独立的高中英语作文篇1
Today in China,many families have only one child.So the children usually doted upon by all family members.Gradually some of them get used to depending on their parents and lack the ability to solve problems independently.
There are some ways to help children to be independent.Firstly,the child should have a chance to see the world around him.He must understand that there are various competitions in this world,and everyone can find his right position in the society only by individual efforts.Secondly,the parents should give the child enough help to make him feel comfortable.Its impossible to ask a child not to depend on parents at once.A child needs help from the beginning.Without any help,the child may lose his faith.At last,parents should let his child make decisions,which can temper his ability to deal with problems.
No parents can accompany the children for the whole life.It is the child himself who is responsible for her own fate.Only an independent person can live and succeed in this world.
今日的中国,很多家庭都只有一个孩子.所以孩子往往成为全家人生活的焦点.有些孩子逐渐养成了依赖家长的习惯,从而导致他们缺乏自己解决问题的能力.
这里有几点可以帮助孩子变得独立.首先,孩子应当正式他周围的世界,每个人只有通过自己的努力才能在社会中找到他自己的位置.其次,家长应给予孩子足够的温暖让他感到舒适.不能要求每个孩子从不依赖父母.孩子需要一个起跑的平台.没有任何帮助,孩子或许会失去信念.最后,家长应让孩子做决定,如何依靠自己的能力解决问题.
没有父母可以陪伴孩子一辈子.决定自己的命运是孩子肩负的责任.只有独立的人才能在这个世界生活并取得成功. 关于独立的高中英语作文篇2
When I was very small, I was so envious about the adults, because they could do whatever they wanted and did not have to depend on their parents. For me, I did not have money and my parents limited my pocket money, so I couldn’t spend the money to buy whatever I wanted. It seems to me that being an adult is my only wish. Some day, I learned from the movie that being an adult was not that as perfect as I thought. In the movie, the man struggled to earn money to pay his bills, what’s more, he had to stay away from his family. Loneliness was always around him. To be independent means we can live our own way and make our own decision. We have more freedom. But at the same time, it also means more annoyance. So why just we enjoy this moment.
在我很小的时候,我很羡慕成年人,因为他们可以做任何他们想做的,不必依赖他们的父母。对我来说,我没有钱,我的父母限制我的零花钱,所以我无法花钱去买所有我想要的。似乎成为一个成年人是我唯一的愿望。有一天,我从这部电影中了解到,作为一个成年人也没有我想象中的那么完美。在电影中,那个人努力挣钱来支付他的账单,更重要的是,他不得不远离他的家人。寂寞总是是围绕着他。独立意味着我们可以有自己的方式生活,做自己的决定。我们有的自由。但与此同时,这也意味着的烦恼。所以为什么不享受这一刻呢。 关于独立的高中英语作文篇3
When we talk about being independent, we often think about leaving our parents and living alone. The mental independence is always ignored by people, mental independence means the person can measure the things and make the right decision. As for the children, even they move out and stay far away from their parents, but sometimes they just can’t control themselves, they will get the bad behavior, like smoking and drinking, their life is losing control. The young people need to cultivate their independent spirit, they should think by themselves, learn to take care of the other people, thus they can be the real independent. When a person grows up, they can be strong enough to support their lives and at the same time, they can be mature enough to make their own decision. They can tell what is wrong and what is right.
当我们谈到成为独立,总是想要离开父母,独自居住。精神上的独立总是被人们忽略,精神上的独立意味着一个人能衡量事情,做出正确的决定。对于孩子来说,虽然他们搬出去,远离父母,但是有时候他们无法自控,养成不好的习惯。比如抽烟和喝酒,他们的生活会失控。年轻人需要养成独立精神,他们应该自己思考,学着去照顾别人,这样才能真正的独立。当一个人成长了,他们才能够足够的强大去养活自己,同时,也能够足够成熟去做决定。他们能区分什么是好,什么是坏。

+ 加入清单Oceans becoming more acidicThe worlds oceans are slowly getting more acidic, say scientists.The researchers from California say the change is taking place in response to higher levels of carbon dioxide in the atmosphere.The lowering of the waters pH value is not great at the moment but could pose a serious threat to current marine life if it continues, they warn.Ken Caldeira and Michael Wickett, from the Lawrence Livermore National Laboratory, report their concerns in the journal Nature.Increasing use of fossil fuels means more carbon dioxide is going into the air, and most of it will eventually be absorbed by seawater.
Once in the water, it reacts to form carbonic acid.Scientists believe that the oceans have already become slightly more acidic over the last century.But these researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with computer models of climate change."This level of acidity will get much more extreme in the future if we continue releasing CO2 into the atmosphere," said Dr Caldeira."And we predicted amounts of future acidity that exceed anything we saw over the last several hundred million years, apart from perhaps after rare catastrophic events such as asteroid impacts."If carbon dioxide release continues unabated, ocean pH could be reduced by as much as 0.77 units, the authors warn.It is not absolutely clear what that means for marine life, however.
Most organisms live near the surface, where the greatest pH change would be expected to occur, but deep-ocean lifeforms may be more sensitive to pH changes.Coral reefs and other organisms whose skeletons or shells contain calcium carbonate may be particularly affected, the team speculate. They could find it much more difficult to build these structures in water with a lower pH.In recent years some people have suggested deliberately storing carbon dioxide from power stations in the deep ocean as a way of curbing global warming.But Dr Caldeira said that such a strategy should now be re-considered."Previously, most experts had looked at ocean absorption of carbon dioxide as a good thing - because in releasing CO2 into the atmosphere we warm the planet; and when CO2 is absorbed by the ocean, it reduces the amount of greenhouse warming.
