When the founder of Facebook, Mark Zuckerbergs daughter was born, he

announced a general decision and surprised the world. Mark told media that he

would donate 99 percent of his fortune to the charity organizations. Some people

wonder why he did not save the heritage for his offspring. In fact, in western

countries, for some rich people, they dont trend to leave much fortune for

their kids, instead, they use the money to educate their children and cultivate

them to be the wise persons. The rich people leave the invisible fortune, which

is their fame. Their children can have more chances to do their business or

receive better education with their family names. The wise rich men know the

best way to educate their offspring. They teach skills and the way of thinking,

which values everything.

地球上的水资源，从广义来说是指水圈内水量的总体。包括经人类控制并直接可供灌溉、发电、给水、航运、养殖等用途的地表水和地下水，以及江河、湖泊、井、泉、潮汐、港湾和养殖水域等。水资源是发展国民经济不可缺少的重要自然资源。在世界许多地方，对水的需求已经超过水资源所能负荷的程度，同时有许多地区也濒临水资源利用之不平衡。

我们中国是世界上十三个缺水国家之一，有许多地区严重缺水，可是，如今人们对水资源却还不够重视，浪费水的现象非常多，例如：洗完手后不关紧水龙头、乱用水、玩水枪这样没有意义的游戏，并且还浪费水、用许多许多的水去洗东西，洗干净了还玩水……如果全国人都这样浪费，那这些水可以用来做许多事情，或许可以拯救一个干旱地区！

缺水，不仅对人类有着威胁，对大自然界也有着紧密的关系，植物，如果没有了水，那就很难生长，吸收不了水分，那么生长不了多久，就会枯竭。动物，更是与人类相同，动物也要吃东西，也要喝水，如果没有了水，动物也很可能渴死。如果植物稀少，那氧气就不会多，人类还会面临着呼吸问题，而且空气的清新度也会减弱，那人类就会呼吸着乌烟瘴气，如果这样，人类就会体弱多病，如果体弱多病，就需要许多药物品，而许多珍贵的药物品，又都是植物，或者动物……

所以，请不要想到，缺水只是会渴罢了，如果不重视这个问题，继续浪费水下去，那么，不仅是我们中国的问题了，要面临的，是全世界的环境与生存的问题！！

Animals Need Protecting

Animals are natural resources that people have wasted all through our history. Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the earth forever. Hundreds more are on the danger list today. About 170 kinds in the United States alone are considered in danger.

Why should people careBecause we need animals, and because once they are gone, there will never be any more. Animals are more than just beautiful or interesting. They are more than just a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems. For example, when

farmers killed large numbers of hawks, the farmers stores of corn and grain were destroyed by rats and mice. WhyBecause hawks eat rats and mice, with no hawks to keep down their numbers, the rats and mice multiplied quickly.

Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger. Quite a few countries have passed laws. These laws forbid the killing of any animal or plant on the danger list. Slowly, the number of some animals in danger is growing.

动物需要保护

动物是自然资源，在整个历史过程中，人类一直在糟蹋着这种资源。人们杀死动物，获得它们的皮毛，把它们当作食物或运动方式，或者只是因为它们碍事。成千上万种动物已经从这个地球上永远地消失了。现在另外上百种动物也上了濒危动物名单。仅荚国大概就有170种被认为处于危险当中。

为什么人们应该感到担忧呢因为我们需要动物，因为它们一旦消失，就永远不会再出现。动物不仅仅是漂亮或有趣。它们不仅仅是人类的食物来

源。在维持自然平衡中，每种动物都有其作用。毁灭某种动物会导致许多问题。比如，农民们如果杀死为数众多的鹰，他们谷物和粮食的仓库就会受到老鼠和田鼠的破坏。 为什么因为鹰吃鼠类，没有鹰控制它们的数量，鼠类就会迅速繁殖。

幸运的是，有些人正在努力帮助拯救这些动物。有些组织筹钱以便人们了解这一问题。他们也努力使政府通过保护濒危动物的法律。很多国家已经通过了法律。这些法律禁止杀害濒危名单上的动植物。某些濒危动物的数目正在慢慢地不断上升。

I’d like to tell you something about my childhood. when i was six years old, i was a lovely girl!

One day, my father saw some fish in the river, so he asked me, why can fish only live in water? i thought about it, then i gave him the answer, because there are some cats on the bank. my father laughed when he heard that. then he said, you are smart! i was happy to hear that.

Maybe you will say, it’s a funny answer. now, i think, it is very interesting. and now i am smart. my parents love me very much. i am so happy to have that childhood.

【参考译文】​

我想告诉你一些关于我的童年的事。当我六岁的时候,我是一个可爱的女孩!

有一天,我爸爸在河里看到一些鱼,所以他问我,为什么鱼只能生活在水里?我想了一下,然后我给了他答案,因为银行里有一些猫。听到这话,我父亲笑了。然后他说,你很聪明!听到这个我很高兴。

也许你会说,这是一个有趣的答案。现在,我想,这很有趣。现在我很聪明。我的父母非常爱我。我很高兴有这样的童年。

水是我们生活的源泉，地球上的每一个生命都离不开水。假如有一天水消失了，那么地球上所有的生物都会随着水的消失而灭绝。

在烈日炎炎的夏日里，当你打开水龙头冲凉澡时，你可否想过那缺水地区人们的心情;当你晚上因为粗心而忘记关闭水龙头时，那一整夜流失的水可能相当于一个缺水地区全部村民的日用水量;当你拿着水枪和伙伴们一起嬉戏的时候，你浪费的水相当于缺水地区一个人的日用水量…….。这一件件鲜明的事例，都说明了水资源是多么的宝贵呀!

但是，环顾四周，破坏水资源、污染水资源的现象屡见不鲜。就拿佳县的佳芦河来说吧!据爷爷说，十几年前，佳芦河的水是那么的清澈，那么的美丽，河的两边绿草衬托着美丽的大石头，犹如一条透明的丝带。河里大大小小的鱼儿游来游去，人们路过此地，口渴时，可以直接饮用佳芦河的美水。可是十几年过去了，佳芦河变样了：河水不再清澈，而是浑浊不清，小鱼不再游动，到处是臭味和垃圾。佳芦河变得简直是一条堆满垃圾的臭水沟，路过那里的人们，总是捂着鼻子快速地跑开。这一切的一切，都是人类破坏水资源的罪证呀!

我们作为地球村的村民，保护水资源，是摆在我们面前刻不容缓的大事。应该记住“黄金有价水无价”，为了我们健康，为了人类的生存与发展，亲爱的朋友们，请行动起来，保护水资源，保护人类的共同家园——地球!

Recently, the news reported that one special kind of rhino from Africa just

passed away, which meant the disappearance of this lovely creature. What a great

pity. The tragedy is caused by the damaged environment, while human being must

be blamed for it, because we have done so many bad things to pollute the

environment and make the nature lose its balance. In order to make up our faults

and save our offspring, it is in need of protecting the environment. As the

ordinary people, we can do the small things, such as do not throw away the

rubbish and join some activities to bring the world green, like planting trees.

Every small act can make a difference. Some day, when we live with the

environment friendly, what we do is worth.

我热爱地球,热爱我们赖以生存的家园.爱她的青山绿水,爱她的碧草蓝天……

在四野飘香的花丛中,我和蝶儿一起嬉戏、欢笑;在郁郁葱葱的森林里,我与小鸟一起追逐、歌唱;清晨,我迈着轻盈的步履去原野上踏青,雾霭缭绕着、白纱般的柔柔地漂浮在空中.吮吸着花草的芳香,欣享着阳光的沐浴,我被陶醉在这如痴如醉的梦幻里;夜晚,我坐在稻谷飘香的农家小院里,仰望着璀璨的星空,聆听着蝉鸣嘹响,蛙声如潮,仿佛置身于一个童话般的王国.春天,我坐在牛背上,在一望无际的大草原上,听那牧歌婉转,牧笛悠扬.夏天,我坐在小船上,任双桨拍打着那碧绿的湖水,看海鸥轻盈地掠过辽阔的湖面;秋天,我站在树下,凝神瞩望着那金黄的叶子一片片地落下;冬天,我站在窗前,欣赏着如絮的雪花在空中翩翩飞舞.在这如诗如画的仙境里,我的心都醉透了!

曾几何时,人们乱砍乱伐,使大自然的生态平衡遭到了破坏.沙丘吞噬了万顷良田,洪水冲毁了可爱的家园,大自然的报复让人类尴尬哑然.梅水溪曾经说过,没有自然,便没有人 类,这是世界一大朴素的真理.一味地掠夺自然,征服自然,只会破坏生态系统,咎由自取,使人类濒于困境.这句话说得一点也不错,人不给自然留面子,自然当然也不会给人留后路,98洪水、2000年的沙尘暴,其实,这就是大自然向人类发出的警示.

曾几何时,人们乱捕乱杀,使人类的朋友惨遭涂炭."千山鸟飞绝,万径人踪灭",这就是对捕杀动物后果的最真实的写照.从大学生的伤熊事件到愚人们的疯狂捕猎,人类是否也将要把枪口对准自己?切记,保护动物就等于保护我们自己.

曾几何时,战争的爆发,使我们赖以生存的星球满目疮痍.炮火对植被的破坏,核辐射对生命的摧残,尽管广岛、长崎上空的蘑菇云已经散去了半个多世纪,可那里依然还是不毛之地.由此可见,和平是全人类绿色环保的重要前提.

真不敢想象,我们如果再这样继续下去,这个世界将会是一幅怎样的惨景呢?地上寸草不生,天空尘沙弥漫,人类将在魔鬼般的尖叫声中化成堆堆白骨.到那时我们只能说,人类曾经属于过地球,但地球将永远不会再属于人类了.

顾炎武曾经说过,天下兴亡,匹夫有责.保护环境与维护生态平衡的历史重任要落到我们跨世纪一代的肩上.让我们都来关爱自然,热爱地球吧,手挽手、肩并肩、心连心地铸起一道绿色环保的大堤,捍卫资源、捍卫环境、捍卫地球、捍卫我们美好的家园吧!

[初一作文精选：保护环境,从我做起

The traffic problem is one of the most serious problems in my hometown.

Recently, more and more people have private car, but the roads are so narrow

that we have to fight against the heavy traffic when we go out. Especially

during the rush hours, cars and buses are unable to move. To make things worse,

many people are killed in the traffic accidents. How miserable it is!

For the sake of our life and security, some measures must be taken to

change the present situation. In the first place, as there are a great many

cars, we should control the number of private cars and vehicles and use the

public transportation more often. Secondly, the government should widen the

roads and build more flyovers, so as to ease the traffic pressure and reduce the

traffic accidents. In addition, the undergrounds and light rails should be

constructed, so that we can have more choices when going out and do not have to

worry about the traffic jams in the future.

I believe the traffic problem could be solved if we devote our actions to

them.

Nowadays environmental protection has become the first thing we have to do, because now the earths environment is under threat.

Now, we know that the earth has been warming, cold place has melted the ice, the water level becomes more and more high, let many coastal countries. More land desertification, disasters are hit, make our life is no longer so carefree.

First of all, we must start from the side.

Forests have been cut down, automobile exhaust emissions... The first will directly affect our lives, because they let we dare not breathe. So, the best way to deal with these problems is to drive less, ride bikes, and riding a bike is good for you! . But although it has been said that and said more than once, but why there are so many cars on the road? So, this method really, a bit not practical.

The simplest is to plant trees, the trees are humans good friends, they can help mankind to many things, such as clean air, and so on. So, a variety of trees, this method is very practical!

In short, our earth wanted us to take good care of yourself, to protect, want to use practical actions to help the earth, make the environment more beautiful!

先如今环保已经成为了我们必做的事，因为现在地球上的环境正受到威胁。

现在，我们知道地球已经开始变暖，寒冷地方的冰已经开始融化，变成的水使水平面越来越高，让许多沿海的国家被淹没。更多的土地沙漠化，天灾不断来袭，使我们的生活不再那么无忧无虑。

首先，我们必须从身边做起。

大片森林被不断砍伐，汽车尾气不断排放……这些首先就会直接影响到我们的生活，因为这些让我们“不敢呼吸”。所以，这些问题最好的解决方法就是少开车，多骑自行车，而且，骑自行车也很有益身体健康!。可虽然一直这样说，而且说了也不只一次，可为什么还是有那么多的车在路上呢?所以，这个方法实在，有点不实用。

最简单的就是种树了，树是人类的好朋友，他们能帮助人类许多事，比如净化空气啦，等等。所以，多种树，这个方法很实用!

总而言之，我们的地球要我们自己去爱护，去保护，要用实际行动来帮助地球，让环境更美好!

Save the earth

How to protect theenvironment has become one of the biggest problems in the world .

It’s our duty toprotect our environment .No matter where we live ,we should do something tokeep our neighborhood clean and tidy .We can collect waste paper or otherwaste things for recycling.We should plant more trees and we should preventthose factories from pouring waste water into rivers,lakes and fields.We shouldn’t leave rubbish everywhere andspit in public places .We mustn’t pick the flowers or step on the grass inpublic.If everyone tries his best to protect the environment ,the world willbecome much more beautiful and our life will be better and better .

As we all know water is very important. We should try to save it. First, when we finish washing the clothes or dishes, we can use the water to clean the floor. Second, If we see the dripping tap, we must fix the tap as soon as possible. Third, we can have a shower instead of a bath because having a bath can waste a lot of water.

winter is my favourite season. because my birthday is in it. it lasts from december to february. in winter it is cloudy, windy, cold and dry. in winter i take off my dress and put on my coat. i can make a snowman, go sking and go skating in it. i can drink chocolate. but i can’t drink cold water and eat ice-creams. winter is white. i like winter very much.

海水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.

The population of the earth is increasing very fast. Humans must make the earth support the increasing population. This has made it necessary for agriculture and industry to develop rapidly.

Such a rapid development produces more and more waste, which goes into the water, the soil and the air. Some of it is made harmless. However, where there is too much of it, the poisonous waste may do great harm to the things around the people.

When farmers add fertilizer to the soil to make plants grow better, or use poison to kill pests, poison is sent into the air, the water and the soil. When birds, fish and people eat the grain, drink the water or breath the air, harm will be done to their health.

The air in big cities is often made very dirty by cars and factories. Millions of tons of waste and poisonous gases are sent into the air with the smoke. In some places, little is done to make the smoke clean before it goes into the air.

Fortunately, people are beginning to realize just how serious the whole situation is. In many countries, laws have been made to stop factories from sending out poisonous gases.

平时，妈妈常会给我讲，面对危险应如何自我保护，每次听到妈妈讲小孩子尤其要提高自我安全防护意识时，我总是不以为然，总觉得危险离我很远。

一个假日的夜晚，单独一人留在家中的我，看坐在沙发上悠闲地看着电视，突然窗外划过一道亮光，紧接着，几声轰隆的雷鸣声响了起来，沉闷的雷声，让我的内心有些许的紧张，倾刻间，外面闪电乱挥，这儿一道，那儿一道，煞是吓人，雷声像在头顶上炸开似的，轰轰作响，我整个人蜷缩在沙发上，期盼着爸妈快点回来。这时，我听到门铃响了起来，我高兴地向着门口飞奔过去，正要打开门，突然想起妈妈说过，听到门铃响，不要急着开门，先透过猫眼看看外面来的是什么人。我惦起脚尖凑近猫眼看了看，是一个完全不认识的陌生人，我心里越发紧张了，我努力让自己镇定下来，站在门边问道：“你是谁？”“小朋友，你一个人在家吗？我是你爸爸的朋友，因为今晚打雷下雨，你爸爸让我过来陪陪你。快开门，让叔叔进去。”一听这话，我有些犹豫了，确实刚刚的雷声，让我有些害怕，我渴望有大人的陪伴，想到这儿，我正想打开门，让那位叔叔进来，这时突然想起妈妈的话：千万不要给陌生人开门。这位叔叔我不认识，万一，他是坏人怎么办，可要是他真是爸爸的朋友，那我不让他进家门，这样会显得很没有礼貌，思量再三，我决定试试他，于是，我对他说：“叔叔，你先等一下，门被我妈妈用钥匙锁住了，她现在就在房间里，我去房间把她找来，让妈妈来给你开门！”一听这话，站在门口的那位叔叔，显得有些慌张，他转身跑了。

爸妈回来后，知道了这件事，都夸我应对得当，成功地保护了自己。

这次的经历，让我意识到自我保护的重要性，也深刻地体会到，遇到坏人时，一定要保持冷静，运用自己的智慧和坏人周旋，以达到保护自己目的！

保护学校环境（二）

The protection of the border is not a new problem for us, and our government has long proposed clear targets for governance. As every ordinary person in real life, although it is impossible to work directly in environmental protection, we can start from small things and start from me. Can you raise your hand when you see the tap in the bathroom? When the battery runs out, can you classify it instead of throwing it away? How about when shopping doesnt use ultra-thin plastic bags? ...... Small things are small, but they reflect how much environmental awareness we have.

Recycling one ton of waste paper can regenerate 800 kg of paper, can save 17 tree. 20 waste recycling boxes can create a beautiful pen container. Recycling one glass bottle to save the energy, can make the bulb light for four hours. Recycling one aluminum can is to save the half oil cans. So we should place the garbage classification, reproduction by the relevant department after recycling reuse!

As long as we start from oneself, starts from the minor matter, everybody joint efforts, perseverance, we will be for the society, also a piece of clear water, blue sky for yourself, I hope everybody can voluntarily protect the environment, to make our environment more beautiful life.

境保护对我们来说并不是一个新问题，我国政府也早就提出了明确的治理目标。作为现实生活中的每一个普通人，虽然不可能都直接从事环保工作，但我们完全可以从小事做起，从我做起。当看到洗手间的水龙头在滴水时，是不是能够举手关上呢?当电池用完后能否分类收藏处理而不是随手扔掉呢?当购物时能否自觉不使用超薄塑料袋呢?……一件件小事虽然都很不起眼，但却体现我们究竟具备了多少环保意识。

回收1吨废纸可再造出800千克好纸,可以挽救17棵大树.回收20个废餐盒可以造出一个漂亮的笔筒.回收一个玻璃瓶节省的能量,可使灯泡亮4个小时.回收1个铝罐就等于节约了半个铝罐的石油.所以我们应将垃圾分类安放,由有关部门回收后再生产再利用!

只要我们从自己做起，从小事做起，大家共同努力，持之以恒，就一定能为社会、也为自己留下一片碧水蓝天，我希望人人都能自觉保护环境，让我们的生活环境更加美好。

因为人的记忆力有选择啊，有的人天生对语言天生敏感，所以记得就快，有的人对历史敏感，记忆历史就比别人快。所以人的记忆力不能一概而论，这是我多年学习的经验，和个人理解。

第一，你不要把英语单词当成中文的象形文字来记，中文的记忆有形象关系，但是单词时无意义的字母排序，背得时候一定要理解英语的发音规律，先要记没个单词的发音，有的发音如tioneror什么的你一定发现了几个字母组合法特定的音，按发音记！

有时候宁肯先记发音！

因为有时候，你甚至能根据发音，你自己就能写出来，何必要背。其实英语的字母单词，不是很规律的，不想拼音的，但还是有一定的规律。

其实背英语单词，不能死记是真的，但是一定要持之以恒，首先要有心理准备，要有自信。

你背英语单词的时候可以边默读便用笔在一张纸上写，就是随便写一些，主要是加深印象。

我的习惯是第一次背时先写5遍/单词，隔天写3遍/单词。过一段时间再重复。这样记虽然慢，但是很扎实。

而且还要注意，背单词应该背词典，就是你背一个词的形式，比如名词，最好翻阅词典，把其他的形式也给背过。这样看起来，似乎比较费脑子，实际上我认为，这样无形中很快，因为你背单词就是要用在阅读上，这样背的话既实用又能无形中体会出英语的变形规律，以后就会背的很快乐。

英语背单词，实际取决于你已经背的单词量。

不是英语专业的人，但是愿意分享我的经验，希望你能背得越来越轻松。
