if you want to understand adversity, take two identical acorns from the same oak tree and plant them in two different locations. plant the first in the middle of a dense forest, and the other on a hill by itself.

要是你想理解什么是逆境,就去拿两颗从同一棵树上摘下来年龄相同的橡树果,并且把它们种到不同的地方。第一颗种在浓密的树林当中,而另外一颗则单独种在一座山上。

heres what will happen. the oak standing on a hillside is exposed to every storm and gale. as a result its roots plunge deep into the earth and spread in every direction, even wrapping themselves around giant boulders. at times it may seem the tree isnt growing fast enough—but the growth is happening underground. its as if the roots know they must ported the tree from the threatening elements.

事情的结果便是这样。那颗长在山上的橡树经历了大风大雨,结果它的根深深地扎进了泥土中间,并不断向四周扩张,甚至把自己置身于巨大的石块当中。有时它可能看起来长的不是很快,但这时它却在地下悄悄生长着,好像它的根知道自己必须快速生长来保护树木免受自然危害的影响。

篇8:封信英语翻译

全文共 1773 字

+ 加入清单

Good morning,everyone! I`m very happy to have this chance to give my

presentation. Before I start my speech, please let me ask you a question. Do you

think you are confident in yourself? If you are, do please raise your hand.

My topic today is “ to Be a Confident Person.”

What is confidence? Confidence is to trust yourself. Confidence is to look

upon yourself. It is not to indulge in self-admiration. It is not to get

extremely arrogant. It is not to get dizzy with success or to be opinionated. It

is just to inspire yourself ahead of a quality of mind, in high spirit, full of

energy. It is to meet the challenges of life in a positive mood. It is to

overcome your inferiority, farewell, to get rid of the trouble of a a ready-made

panacea.

Remember, I have just entered junior high school. In the face of the

challenge of new environment, in the face of so many new courses and learning

contents, I lost faith in my own and gradually developed a psychological sense

of inferiority. Achievement glided ceaselessly. It is a teacher and mother who

encouraged me and let me regain confidence. Gradually, my grades got higher and

higher and everything began to go on well. Gradually I adapted to the life in

middle school.

Friends, lets say goodbye to inferiority. Let’s be a confident person.

Because: only if you have self-confidence, can you control yourself; only if you

have confidence, can you achieve success and create your a brilliant life of

your own!

大家好!

今天我演讲的题目是:做一个自的人。

什么是自信?自信,就是自己信得过自己,自己看得起自己。它,不是孤芳自赏,也不是夜郎自大,更不是得意忘形和自以为是;而是激励自己奋发进取的一种心里素质,是以高昂的斗志,充沛的干劲迎接生活挑战的一种乐观情绪;是战胜自己,告别自卑,摆脱烦恼的一种灵丹妙药。

还记得,我刚刚升入初中时,面对新的环境,面对那么多的新的课程和学习内容,我对自己失去了信心,逐渐产生了自卑心理,成绩不断下滑,是老师和妈妈及时帮助我、鼓励我,让我重新找回自信。渐渐的,我的学习成绩及各个方面都有明显进步,逐渐适应了初中的生活。

朋友们,让我们告别自卑,做一个自信的人吧。因为:只有拥有自信,才能拥有自我;只有拥有自信,才能走向成功,才能创造自己辉煌的人生。

篇11:关于代沟英语作文高中

全文共 1710 字

+ 加入清单

The generation gap is unavoidable in almost every family, which brings

about a number of conflicts in a family. In my opinion, to limit the bad effects

of the generation gap, each family should use the following three methods:

First of all, it is important that family members discuss openly about

their pleasures or sadness in childhood in family gatherings. This activity does

not only create a close relationship but also help build up understanding among

all members. For instance, once children are aware that their grandparents and

even their parents did not have a good upbringing during their hard childhood,

they will stop complaining about the previous generations’ obsoleteness. In the

meantime, once old people realize young people are nurtured in a new modern way,

it is easy for them to be tolerant of young people’s new habits or hobbies.

Secondly, people of each generation should not develop a very high feeling

about themselves. In order to do that, they should not think that they are the

only right people in their family because each person has his or her own

limitations. Teenagers would realize that their parents have to struggle with

pain to support them financially, and they would stop rebelling their

strictness. Parents would realize that their children’s new style does no harm

to their studies and stop imposing their own unsuitable standards on their

children.

Finally, the generation gap and its bad effects can be limited if all

members cooperate to build up a close-knit family relationship and a harmonious

atmosphere in which they are open and tolerant of each other. I strongly believe

that each family, by doing that, can enjoy a cozy atmosphere with minimum

interference by the generation gap.

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.
