温暖的重要性初三

全文共 837 字

+ 加入清单

还记得去年曾经去过的灵隐寺,香火袅袅的庙宇里,虔诚的身影长跪不起。高高的佛像面目温暖慈善,注视着众生。这时候,我也不可免俗地跪拜下去:“愿所有苦难的人们得到温暖,愿所有善良的心灵得到庇佑。”

立身合十,佛含笑如常。

此刻,心思又飘向远方,想起了故乡的外婆。我的外婆慈善和蔼,信奉佛家思想,我也曾在书中读到过,当年释迦牟尼于菩提树下悟得的禅理,乃是以给予众生平等的爱与温暖为起步的,或许是从小的耳濡目染吧,于我,佛家思想是用生生不息的爱织成的馨香的春衫,给予众生芳香与温暖。

小学、初中,都参加过学校组织的去敬老院的活动,那里的老人不是没有子女,就是因为子女照顾不到他们而被送到敬老院的。谁不想拥有天伦之乐,谁不想拥有家庭的温暖?所以,当我们这一群活泼的孩子,热情的少年出现在他们面前时,他们该有多欣慰啊。

我们与老人们谈心、下棋,还为他们打扫整理,当自己轻轻掸去老人们身上的一点灰尘时,我看到她的笑容如菊花般?魍瘢??ψ潘档溃骸昂煤⒆樱?矣侄嗔烁鏊锱?。

以前,堂妹生病住院了,我去医院看她,认识了一个邻床的女孩。当我与她讲起学校里的种.种趣事时,她黑如漆点的瞳仁里,闪着亮亮的希望的光,露出了舒心的笑容。

临走前,我送给她一串风铃,风拂铃动,摇曳而出的,是童年的快乐乐章。

我一直以为,即使自己仅有一点点的热,也要去温暖别人,点亮暗处的明灯,就如同佛手中的甘露,即使给不了整个春天,但所润之处还是萋萋胜碧,花木扶疏。

佛思影响了一代又一代如我一般的后来人。是心怀中的爱与善,升华了心灵,使我们的心被惊凉时,找到温暖。

在这事无双美,福无全至的人间行走,我们都是那瘸腿的铁拐李啊!要不是互赠灵药,互相温暖,谁又能走得如此踏实?

看到蹒跚的老人请向他伸出温暖的手,看到在寒风中抖瑟的孩子请为他披上温暖的春衫。“问莲心,有丝多少,莲心知为谁苦?”人心己心,旁人的苦痛也会丝丝蔓上我们柔软的心房。

如佛所言,我们都是在大化岸边同饮一溪水的人,愿所有的人都心存甘泉甜醴,予人温暖,在这岸边携手,且听风吟。

in the early years of the chinese republic, duan wu was also celebrated as "poets day", due to qu yuans status as chinas first poet of personal renown.

I thought I could get up earlier to go to school the next morning so that I could finish my homework before class. But the next morning I was not able to get to school in time because of the traffic jam. I was punished by the teacher.

篇7:海洋水盐分的英语作文

全文共 2377 字

+ 加入清单

盐度如果我们分析海水的盐度,会发现地区间只有轻微的变化,然而有些小的变化是重要的。

导致海洋的盐度变化的基本过程有三个,其中之一是通过蒸发的方式即把液态水转化为水蒸气来减少海洋中的水分。

这样由于盐留了下来,所以盐度增大。

当然,如果这种方式走向极端,将会余下白色的盐晶体。与蒸发相反的是降水,如降雨,由此水被加入海中,海水被稀释,从而盐度降低。

这种情形会发生在大量降雨的地区,或江河入海岸处。因此,盐度通过蒸发减少水分而上升或通过降水或径流增加淡水成分而下降。一般来说,在阳光很

强烈的热带地区,海水的盐度略高于世界上其它没有热带那样多的蒸发的地区。同理,在江河稀释海水的海岸地带,海水盐度略低于其它海区。

第三个可以变更盐度的过程与海洋中冰的形成和融化有关。海水冻结时,溶于其中的物质被留了下来。这样,在新形成的海

水冰面的正下方的海水比在冰形成之前有更高的盐度。

当然,当冰融化的时候,会降低周围水中的盐度。

在南极洲边缘的威德尔海中,结冰过程增加低温海水的盐度,从而形成了浓度最大的海水。这些大密度的海水下沉,可以在世界海洋的深水域发现。

if the salinity of ocean waters is analyzed, it is found to vary only slightly from place to place. nevertheless, some of these small changes are important. there are three basic processes that cause a change in oceanic salinity. one of these is the subtraction of water from the ocean by means of evaporation--- conversion of liquid water to water vapor. in this manner the salinity is increased, since the salts stay behind. if this is carried to the etreme, of course, white crystals of salt would be left behind.

the opposite of evaporation is precipitation, such as rain, by which water is added to the ocean. here the ocean is being diluted so that the salinity is decreased. this may occur in areas of high rainfall or in coastal regions where rivers flow into the ocean. thus salinity may be increased by the subtraction of water by evaporation, or decreased by the addition of fresh water by precipitation or runoff.normally, in tropical regions where the sun is very strong, the ocean salinity is somewhat higher than it is in other parts of the world where there is not as much evaporation. similarly, in coastal regions where rivers dilute the sea, salinity is somewhat lower than in other oceanic areas.a third process by which salinity may be altered is associated with the formation and melting of sea ice. when sea water is frozen, the dissolved materials are left behind. in this manner, sea water directly materials are left behind.

in this manner, sea water directly beneath freshly formed sea ice has a higher salinity than it did before the ice appeared. of course, when this ice melts, it will tend to decrease the salinity of the surrounding water.in the weddell sea antarctica, the densest water in the oceans is formed as a result of this freezing process, which increases the salinity of cold water. this heavy water sinks and is found in the deeper portions of the oceans of the world.

When the sun begins to set behind the mountains, its long rays light up the green fields. The clouds in the sky also begin to glow with a golden light, and the mountains are really colourful.

When the sun begins to set behind the mountain, it looks like a red ball. Its light fills the sky and changes the colour of the clouds from gold to red.

When the sun is gone altogether behind the mountain, the clouds turn grey and the mountains become black.

Dream is public property, everyone has a dream, there were dreams to struggle the rights. The poor are poor, because there is no struggle for the dream of courage and perseverance; The rich are rich because they fight for a dream. What can dream? Must have different definition in everybodys heart. Some people think that the dream is false; Others think unattainable dream, it really... ; I think: the dream regardless of high and low, regardless of their size, there is no false and true.

I have met all kinds of people in the pursuit of dreams, some of them because of others opposition, sitting there hesitation, some because they cant do, sitting in the depressed; Others because of his dream too far-fetched, therefore, give up your dream. I am sad also very puzzled: "why do they give up their dreams? Yao is hard work can realize their dreams, and look forward to success. But, they dont have to do so, they chose to escape?"

The ancients there is a saying: "there are paying is not necessarily return, but not paid will not return". Whether did finally get the corresponding return, but I believe that: in the stick to dream on the way, there must be a make us unexpected harvest. And, of course, everyone has the value of life in this world, there are some an unrealized dream, chasing for the dream, struggle for the dream. Dream is everyones right to the pursuit of the process is also enjoy the process. To dream into reality at that moment, you will feel the joy and pride.

So, how important it is for a dream. However, in the process of realizing our dreams, dont let the problem by the nose, but toward the dreams, let the dream for your navigation. Sometimes the biggest obstacle to achieve your dreams tend to be yourself. Love spell will win, as long as toward a target unremitting struggle finally will belong to you.

梦想是大家公共财产,每个人都有梦想,都有为梦想而奋斗的权利。穷人之所以穷,是因为没有为梦想而奋斗的勇气与可毅力;富人之所以富,是因为他们为梦想而奋斗拼搏。可梦想到底是什么?想必在每个人心中都有不同的定义。有的人认为梦想是虚假的;有的人则认为梦想高不可攀,它实在……;我认为:梦想不分高低,不分大小,也没有虚假与真实之分。

我曾经见到了各种在追求梦想的人,他们有的因遭到别人的反对,坐在那里犹豫不决,有的因碰到自己无法做的事,坐在那垂头丧气;还有的人因自己的梦想太遥不可及,因此,放弃了自己的梦想。我既难过也很不解:“为什么他们要放弃自己的梦想呢?明明是努力就可以实现自己的梦想,从而走向成功的。但是,他们没有这么做,而是选择了逃避呢?”

古人有句话说:“有付出不一定有回报,但不付出就一定没有回报”。不管最后有没有得到相应的回报,但我相信:在坚守梦想的路途中,一定会有令我们意想不到的收获。当然,每一个人都有生活在这个世界上的价值,都有一些未圆的梦,为梦而追逐,为梦而奋斗。追求梦想是每个人的权利,追求的过程也是享受的过程。到梦想变成现实的那一刻,你会感到无比喜悦,自豪。

由此可见,梦想是多么重要。不过,在实现梦想的过程中,不要被问题牵着鼻子走,而是朝着梦想前进,让梦想为自己导航。有时实现梦想的最大障碍往往是自己。爱拼才会赢,只要朝着一个目标奋斗不懈最后的灿烂将会属于你。

Something must be done to stop the pollution. And I think it’s a great shame to waste while millions are in great need of water. I think what we can do is that we have to save every drop of water as possible as we can. For example, we must turn off the tap immediately after we use it. We can use a basin to wash our hands and faces. It’s also a good idea to encourage my friends and family members to join me! Only in this way can we live happily.

人体有着90%以上的,因此水是必不可少的。也不是什么水都能喝,许多水都是对人体有害的。

生水及未处理过的水,这种水常含有各种各样的细菌、病毒和寄生虫。喝了生水,很容易引起疾病和寄生虫感染。况且如今工厂、生活废水、农药残余等污染严重,喝生水引起疾病更是高频率。

死水,也就是长时间不动的水,常饮这种水,对未成年人来说,会使细胞新陈代谢明显减慢,影响生长发育;中老年人则会加速衰老;老化水及死水中的有毒物质,也会随着水贮存时间增加而增加。

沸腾时间长和反复煮沸的水也不能喝。这种水因煮过久,水中不发挥性(重金属)含量高。久饮这种水,会干扰人的消化功能,造成昏迷,甚至死亡。

蒸馏水是实验室用的水。这是普通水蒸发后的水蒸气在空气中出现“液化”而形成的一种干净、无任何杂质的水。常饮这种水,会导致机体严重缺乏各物质,疾病便闻风而来。

不开的水也不能喝,人们饮用的自来水,虽然经消毒灭菌处理过。但是,终有生命顽强,漏网之鱼的细菌未被消灭,而低温无法杀死这些“佼佼者”。而这些细菌,有害物质大都有致癌作用。那么,怎样净化水?

其实很简单,化学实验中的过滤法既简单方便又实用。面对浑浊的水,要将其净化,可以先沉淀(也可直接过滤),然后只取上部分水,用一根小棒引流,在三层滤纸上过滤。这样,不溶物质便留在了滤纸上,为了使水更加洁净,可以在其它干净滤纸进行多次过滤,最后,再加热使水沸腾杀菌。这样,便得到了一杯较干净的水。

在生活中,人们也“依样画葫芦”,在水质差的地方,往往制造了各种大同大异的“净水器。”在水龙头口包裹几层纱布便是最原始的方法。

我相信将来的新兴产业肯定有净水处理器,未来的水也会越来越安全。
