A fern that hyperaccumulates arsenic(这是题目,百度一下就能找到原文好,原文还有表格,我没有
翻译)
A hardy, versatile, fast-growing plant helps to remove arsenic from contaminated soils
Contamination of soils with arsenic,which is both toxic and carcinogenic, is widespread1. We have discovered that the fern Pteris vittata (brake fern) is extremely efficient in extracting arsenic from soils and translocating it into its above-ground biomass. This plant —which, to our knowledge, is the first known arsenic hyperaccumulator as well as the first fern found to function as a hyperaccumulator— has many attributes that recommend it for use in the remediation of arsenic-contaminated soils.
We found brake fern growing on a site in Central Florida contaminated with chromated copper arsenate (Fig. 1a). We analysed the fronds of plants growing at the site for total arsenic by graphite furnace atomic absorption spectroscopy. Of 14 plant species studied, only brake fern contained large amounts of arsenic (As;3,280–4,980 p.p.m.). We collected additional samples of the plant and soil from the contaminated site (18.8–1,603 p.p.m. As) and from an uncontaminated site (0.47–7.56 p.p.m. As). Brake fern extracted arsenic efficiently from these soils into its fronds: plants growing in the contaminated site contained 1,442–7,526
p.p.m. Arsenic and those from the uncontaminated site contained 11.8–64.0 p.p.m. These values are much higher than those typical for plants growing in normal soil, which contain less than 3.6 p.p.m. of arsenic3.
As well as being tolerant of soils containing as much as 1,500 p.p.m. arsenic, brake fern can take up large amounts of arsenic into its fronds in a short time (Table 1). Arsenic concentration in fern fronds growing in soil spiked with 1,500 p.p.m. Arsenic increased from 29.4 to 15,861 p.p.m. in two weeks. Furthermore, in the same period, ferns growing in soil containing just 6 p.p.m. arsenic accumulated 755 p.p.m. Of arsenic in their fronds, a 126-fold eichment. Arsenic concentrations in brake fern roots were less than 303 p.p.m., whereas those in the fronds reached 7,234 p.p.m.
Addition of 100 p.p.m. Arsenic significantly stimulated fern growth, resulting in a 40% increase in biomass compared with the control (data not shown).
After 20 weeks of growth, the plant was extracted using a solution of 1:1 methanol:water to speciate arsenic with high-performance liquid chromatography–inductively coupled plasma mass spectrometry. Almost
all arsenic was present as relatively toxic inorganic forms, with little detectable organoarsenic species4. The concentration of As(III) was greater in the fronds (47–80%) than in the roots (8.3%), indicating that As(V) was converted to As(III) during translocation from roots to fronds.
As well as removing arsenic from soils containing different concentrations of arsenic (Table 1), brake fern also removed arsenic from soils containing different arsenic species (Fig. 1c). Again, up to 93% of the arsenic was concentrated in the fronds. Although both FeAsO4 and AlAsO4 are relatively insoluble in soils1, brake fern hyperaccumulated arsenic derived from these compounds into its fronds (136–315 p.p.m.) at levels 3–6 times greater than soil arsenic.
Brake fern is mesophytic and is widely cultivated and naturalized in many areas with a mild climate. In the United States, it grows in the southeast and in southern California5. The fern is versatile and hardy, and prefers sunny (unusual for a fern) and alkaline environments (where arsenic is more available). It has considerable biomass, and is fast growing, easy to propagate,and perennial.
We believe this is the first report of significant arsenic hyperaccumulation
by an unmanipulated plant. Brake fern has great potential to remediate arsenic-contaminated soils cheaply and could also aid studies of arsenic uptake, translocation, speciation, distribution and detoxification in plants. *Soil and Water Science Department, University of

积累砷的蕨类植物
耐寒,多功能,生长快速的植物,有助于从污染土壤去除砷
有毒和致癌的土壤砷污染是非常广泛的。我们已经发现,蕨类植物蜈蚣草(凤尾蕨)对从土壤中提取砷和转运到地上部生物量是非常有效的。据我们所知这种植物,是第一个已知的砷超富集植物以及也是第一种在已发现的蕨类中可以作为超富集植物,它有许多属性比如建议使用在砷污染土壤的修复。
我们发现被铬砷酸铜污染的生长在佛罗里达州中部的一个站点的凤尾蕨图1a)。我们用石墨炉原子吸收法分析了在站点正生长植物叶子总砷的吸收光谱。 对于14种研究植物物种中,只有凤尾蕨植物中含有大量的砷(含量;3280–4980 ppm)。我们从受污染的站点(18.8–1603 ppm)和未受污染的站点(0.47–7.56 ppm)收集更多的植物和土壤样品。凤尾蕨从土壤中有效吸收砷转运到其叶子中,在受污染的站点生长的植物,含有1442–7526 ppm的砷和那些未受污染的站点包含11.8–64 ppm的这些值是比那些正常的土壤中生长的植物的高很多,其中包含小于3.6 ppm的砷。
对于含有高达1500 ppm砷的疏松土壤中,凤尾蕨植物可以在很短的时间内吸收大量的砷进入它的叶子(表1)。在掺入1500 ppm砷的土壤中蕨类叶子中砷浓度是不断增长的,在两周内砷含量从29.4增加到15861 ppm。在蕨类叶子中的砷,是126倍的富集。凤尾蕨根的砷浓度小于303 ppm,而那些在叶的浓度达到7234 ppm。
加入100 ppm的砷显著刺激蕨类生长,导致在与对照相比,生物量增加了(数据未显示)。
经过20周的增长,用1:1甲醇:水的方法提取该植物用高效液相色谱法–电感耦合等离子体质谱法来平衡砷。目前几乎所有的砷是相对无毒的无机形式,几乎没有检测到有机砷物种。作为(Ⅲ)的浓度叶(47-80%)与根(8.3%)相比更多,表示AS(V)被转换AS(III)在根转运到叶的过程中。
以及从土壤中除去砷的植物含有不同浓度的砷(表1),从土壤中去除含砷的凤尾蕨也含有不同形态的砷(图1C)。再着,高达93%的砷主要集中在叶。 虽然feaso4和AlAsO42H2O在土壤中的相对不溶,凤尾蕨富集的砷来自这些化合物进入它的叶状体(136–315 ppm)在3级–6倍大于土壤砷。凤尾蕨是裸子植物,并广泛栽培归功于许多地区气候温和。在美国,它生长在东南部和加利福尼亚南部。蕨类植物是有多种有优点,耐寒,喜欢阳光(不寻常的蕨类植物)和碱性环境(如砷是更有效)。它具有相当大的生物量,而且常年生长迅速,易于繁殖。

在中西部一个大城市的交通法庭里,一位年轻女士被带到法官面前,她由于开车闯红灯被开了罚单。女士向法官解释,她是一名学校老师,请求法官马上处理她的案子,以便可以赶回去上课。法官眼中闪过一丝狡黠,说道:“你是学校的老师,对吗?女士,我马上要实现我毕生的愿望了。在那张桌子旁坐下,写‘我开车闯了红灯’500遍。
In the traffic court of a large mid-western city, a young lady was brought before the judge to answer a ticket given her for driving through a red light. She explained to his honor that she was a school teacher and requested an immediate disposal of her case in order that she might hasten on to her classes. A wild gleam came into the judge's eye. "You are a school teacher, eh?" said he. "Madam, I shall realize my lifelong ambition. Sit down at that table and write 'I went through a red light' five hundred times."
一个男孩说她的母亲,“妈妈,上帝是男人还是女人?”
妈妈认为这一段时间,说:“好吧,儿子,上帝是男人和女人。”
儿子是混乱的,所以他问:“上帝是黑人还是白人?” 这位母亲回答说:“上帝是黑色和白色,亲爱的。”
他的儿子,还好奇说,一段时间后,“上帝是同性恋或直,妈妈?”
这位母亲,变得有点儿担心,回答:“孩子,上帝是男人也是女人。”
儿子想想,他的脸亮起来时,他认为他终于回答他的问题:“上帝是迈克尔杰克逊?” A boy says to her mother, "Mom, is God a man or woman?"
The mom thinks a while and says, "Well, son, God is both man and woman." The son is confused, so he asks, "Is God black or white?"
The mother replies, "God is both black and white, honey."
The son, still curious, says after a while, "Is God gay or straight, mommy?"
The mother, getting a little worried, answers, "Son, God is both gay and straight."
The son thinks about it, and his face lights up when he thinks he finally has answered his question: "Is God Michael Jackson?"
TO RISE EARLY 论早起
I do not know the reason why some people want to get up late. They will never have the opportunity to enjoy the fresh air and calmness of the morning. This is indeed a quite regrettable thing.
To rise early is a good habit which we should develop. Why? Because the best time when we can pursue our studies is in the morning. In addition, early rising is also good to our health. I hope that everybody our knows the reason why we must rise early.
我不知道某些人要晚起的理由。他们永不会有机会来享受早晨的新鲜空气和宁静。这真是一件发令人遗憾的事情。
早起是我们应该养成的一种良好习惯。为什么?因为早晨是我们从事学业的大好时间。再者,早起对我们健康也有益处。我希望每个人应该知道我们必须早起的理由。
道歉信
亲爱的亨利,
很对不起,你的随身听被损坏,由于我的粗心大意。
这在课堂汤姆早上借你的随身听,放在桌上一听完广播。我们相互追逐并具有休会期间的乐趣。本人在桌子掀翻在不知不觉你的随身听。 ,并没有工作了。现在的第一件事我必须做的是午餐后写信给你表示深深的遗憾。我希望你能原谅我的粗心大意我。
我想更换或支付你的价值。请你告诉我,你更喜欢?

Letter of Apology
Dear Hey,
I am terribly sorry that your walkman was damaged owing to my carelessness.
This morning in the classroom Tom borrowed your walkman and put il on the desk after listening to the radio. We were chasing each other and having fun during the break. I knocked your walkman off the desk without noticing it. And it didn't work any more. Now the first thing I hasten to do after lunch is to write to you to express my deep regret. I hope you will excuse me for my carelessness.
I want to replace it or pay you its value. Will you please tell me which you prefer?
Yours truly,
Brown
My Cat
I have a cat named Mimi. Its hair is as white as snow. I often play games with it. It amuses me a lot and I treat it as a little friend. Every morning, I would say goodbye to it before I go to school and Mimi would wave its front-legs to me. It brings me a lot of pleasure. But it takes time and costs money to keep the cat. My parents and I spend much time taking care of it, feeding it and cleaning it. We have to clean the house from time to time, or the cat will make them dirty and smelly.
我的猫
我有一只猫,名叫咪咪。它的毛像雪一样白,我经常和它一起玩。它使我很开心,我也把它当小朋友一样对待。每天早上,我去上学之前都会跟它说再见,它也人向我晃晃前爪。它给我带来了很多快乐。但是,养猫是要花费时间和金钱的。我父母和我花费很多时间照看它,喂它饭,给它洗澡。我们得经常打扫房间,否则,猫就会把屋子弄得又脏又难闻.

China has been a powerful country for the most part of the past three thousand years. China is now rising again. Why is that so surprising to people? History is the best evidence. The rise of China is just a matter of when, not if. Plus, do you want $100 jeans? Do you want $200 shoes? Do you want $3000 computers? If the answers are NO, you\'d better thank China and appreciate the benefits that it brings to your daily life.

It is very sunny today, the sky is blue and clean, there are some blue clouds in the sky, they look like white sheep, how beautiful!
many students are playing on the playground, the sun is shining brightly, the air is very fresh,some birds are singing in the trees, what a happy day! "Sorry" First
There is one word that is on the lips of Americans, day and night: "Sorry".
One time as I was walking on the street, a young man ran by hurriedly,brushing
against my handbag. Even as he continued on his way, he turned back and said "sorry" to me. Even in a rush, he didn't forget to apologize.
One day, after(转 载于:wWw.zhAoQT.neT 蒲公 英文摘:英文小短文加翻译) I bought a mango, the salesman was giving me the change,but I wasn't ready for it and a coin dropped to the ground. "I'm sorry," he said while bending down to pick it up. I was puzzled - why would he apologize when it was my fault?
Another time, I stepped on a man's foot in an escalator. At the same time,we both said "sorry." I thought it interesting: was it really necessary for him to apologize? Later on, an American friend explained to me that according to the American mentality, the
escalator is a public place, and everyone should be able to stand in it. After someone occupies a position in the elevator,making it difficult for someone else to find a place to stand, isn't it necessary to express an apology?
If you go to the movies and the tickets happen to be sold out, the ticket seller will say: "Sorry, the tickets are sold out."
Whenever one of your hopes goes unfulfilled, an American will say "sorry," as a sign of sympathy.
During my stay in America, I often came across situations in which I was supposed to say "sorry." Gradually, I realized that when friction occurs in daily life, Americans don't care much about who is responsible; if someone important and she is very busy, the
secretary will say: "sorry."If someone is troubled, a "sorry" is always necessary. When this happens, even if the other person is hurt, the "sorry" cools tempers - and human
generosity is displayed. Perhaps this is why I never saw anyone quarreling on the buses, subways or streets of America.
"Sorry"先行
有一个词,从早到晚挂在美国人的嘴边上,那就Sorry(对不起)。
有一次走在街上,一个有急事的年轻人匆匆跑过,碰了我的提包,他边跑边回过头来冲我喊sorry,匆忙中他也没忘记表示歉意。
一次我买芒果,小贩把零钱找给我,我没接好,一个硬币掉落到地上。I'm
sorry.小贩边说边弯腰拣起硬币递给我。我觉得挺不可思议,明明是我自己手脚不利索,他为什么要道歉?
有一次,我乘电梯时不小心踩了一位先生的脚,我赶忙说了一声sorry,可同时,从那位先生的口中也冒出了这个词。我不禁暗自发笑:你有什么必要sorry呢?事后一个美国朋友解释,按照美国人思维方式,电梯间是公共场所,谁都有权站在那儿。由于自己首先占据一块地方,别人才没有足够的地方站稳当,难道不该表示sorry吗?
到电影院去买票,赶上没票,售票员便会说:“对不起,票卖完了”。
凡是你的愿望得不到满足,美国人便会说声对不起,表示他们对此也感到遗憾,使你感受到同情之心。
在美期间,我常常遇到这类本应该由我说对不起的事情,渐渐地我悟出了其中原委:当生活出现小摩擦时,美国人并不去考虑是谁的责任,只要是给对方带来了不便,都要说一声sorry。
这样一来,即使有一方受点伤害,在人家的sorry声中心境也会平和下来。而没受伤害的一方则体会到人与人之间的友善,这恐怕也是我从未在美国的公共汽车、地铁、街道上看到有人吵架的原因吧。
