World Environment Day is started from 1972, which is established by the United Nations General Assembly for raising global awareness to take actions to protect the Nature. The establishment of World Environment Day shows people’s the cognition and the attitude to the environmental problem, and expresses our human beings’ desire of pursuing the better environment. Every year the United Nations Environment Program proposes a theme, and the 2014 theme of this day will focus on ‘Small Island and Climate change’ and the slogan is “Raise Your Voice Not the Sea Level”.

世界环境日，起始于1972年，它是联合国为了提高全球的环保意识而创建的。环境日的创立展现了人们对环境问题的认识和态度，表达了人们对美好环境的追求渴望。每一年联合国环境规划署都会提出一个环境日主题，而的主题主要着重于小岛屿与气候变化，今年的口号是“提高你的呼声，而不是海平面”。

World Environment Day can be celebrated in lots of ways, for instances, planting trees, doing some recycling, participating the clean-up campaigns and so on. Certainly people can also do something simple, like going to work by bus instead of private cars. I believe if everyone takes environmental actions as a habit, we are doing a big difference for the better environment.庆祝世界环境日的方式多种多样，例如植树，对废物进行循环利用，参加清洁行动等等。

当然，人们也可以做些简单的小事来纪念，比如说不做私家车上班，改乘公交车去上班。我相信只要大家都将这些环保小事当作习惯，我们将会为建造美好环境做出重大贡献。

这节自然课是讲动物的世界，沙萱老师让同学们自己用魔法到海洋里探索，同学们都喜出望外。

等他们睁开眼，周围都是清凉的海水，这节课沙萱老师没有跟来，原因是不想让孩子们太过拘束。

“哇，你看，小丑鱼。”李一一指着旁边一条小鱼说道。

“哇，真的！”大家都围了过去。“你看，是河豚！”不知是谁又大喊一声。

海里有很多不认识的鱼类，大家都玩的不亦乐乎。

突然，江子玡打颤地指着前方说道：“你，你们看，鲨鱼！”

同学们都向江子玡指的地方望去，顿时，一些学生尖叫起来，只见鲨鱼那庞大的身躯正向他们游来，尖尖的牙齿让人见了就忍不住发抖。

“它会不会吃了我们啊？”一个弱弱的声音响起。“鲨鱼是只吃鱼的，我们可不在它的菜单上，虽然有时它们会饥不择食，需要小心，但我们还有魔法呢。”

被艾米丽这么一提醒，他们才想起自己会魔法。一时间，一些胆大的同学竟跑到鲨鱼旁边，观察起来。“哎，听说鲨鱼有三百多种，是早在恐龙出现前三亿多年就已经存在，距今已有四亿多年了。”田甲由说道。

“四亿多年！”江子玡目瞪口呆地望着鲨鱼。

同学们看到鲨鱼并没有攻击江子玡和田甲由，又开始热闹起来。

大家在海里都玩得差不多了，艾米丽提议去大森林去看看。

到了大森林，周围都是郁郁葱葱的树木，同学们四处环望，这一环望，可把他们的冷汗都吓出来了，一个豺群正虎视眈眈地盯着他们，前脚微曲，后腿抓地，做好随时前扑的准备。

江子玡等人赶紧用魔法逃走。

“呼，吓死我啦！”艾米丽抹了一把头上的冷汗。

“是啊，差一点我们就命丧豺口了！”李一一附和着说道。

“我听说豺群有一种很残忍的独门绝技，当它们遇到比自己体形大的野猪野牛时，会选好时机，扑上它的背上，把爪子伸到它的肛门里，将肠子掏出来，猎物就命丧黄泉了。”当江子玡说到这里时，李一一等人不禁下意识回头看了一下。“

那狼和豺谁厉害呀？”一个女同学好奇地问。

“正常来说都是狼比较厉害，因为即使是最强壮的公豺比起一个弱小的母狼，也是整整低了一个肩胛。而且豺最拿手的掏肛门，在狼身上也展不开威力，因为不没等豺到狼背上，狼就会扭转狼腰用尖牙厉爪去对付豺了。”这次艾米丽倒是抢在江子玡前说了。

这时，一阵脚步声在他们耳边响起，他们回过头，是象群。这时，象群在夕阳的余辉下是那么的威武。江子玡等人躺在草地上，静静地看着夕阳。“

森林真是一个神秘而有趣的地方啊！”不知是谁说了一声。

突然，一阵口哨声响起，是沙萱老师的集合号。江子玡等人这才恋恋不舍地回到了教室，但他们的心还依然在神秘而有趣的海洋与森林。

There are more and more endangered animals at present,so how to protect them has been our task of top priority .Its wrong for people to hunt animals for their meat and feather,for they are our good friends.

We should protect them instead of killing them.Giant pandas,which are one of the endangered animals,live in the forests and live on bamboo lealves.They can just live safely in the natural protection zones.We should stop killing animal and protect them.

目前有越来越多的濒危动物,所以如何保护他们一直是我们的重中之重的任务。是不对的人猎杀动物的肉和羽毛,因为他们是我们的好朋友。

我们应该保护他们,而不是杀死他们。大熊猫,这是濒危动物之一,生活在森林和住在竹lealves。他们可以安全地生活在自然保护区。我们应该停止杀害动物和保护他们。

我非常喜欢我的小螃蟹,因为它给我带来了许多乐趣,在我学习之外都是它陪我玩,让我增长了许多课外知识.

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。

Although repeatedly by the peoples misunderstanding and discrimination, but jean valjean always abide by the promise of the bishop, silently to do an honest, kind person.

看完《悲惨世界》一书，冉阿让高大的形象始终浮现在我的眼前。他乐于助人，淳朴善良，品格高尚，虽然由于生活所迫，曾犯过一些错，但这并没有影响他的人格，因为他用了一生的时间在艰辛和逆境中不断地完善自己。

冉阿让失业了，因为生活贫因，他偷了一块面包，就被抓住关进监狱，万恶的旧社会!出狱后，一心想报复的他受教主的感化恢复了对生活的信心并立志从善，他来到蒙特亿，改名马德兰，开办工厂，成了富翁，帮助了许许多多的人，当上了市长。然而，为人正直的他由于不想让别人替他顶罪又被抓进监狱……

多么善良的冉阿让，他以德报怨，乐于助人，抚养孤女，不求回报。为了让珂赛特获得幸福，勇于坦言自己的真实身份，这需要多大的勇气，需要多大的爱心啊!虽然一再地受人们的误解和歧视，但冉阿让始终默默地遵守对主教的诺言，做一个正直，善良的人。

我为冉阿让而感动，如果我们都能像冉阿让那样勇敢面对自己的错误，尽自己所能去改正，以一颗博爱的心去看世界，那我们的世界将变得更美好。我为冉阿让而难过，为他报不平，如果冉阿让生活在社会主义的中国，那么他的经历也许就不会那么坎坷了。

Orcas are not related to whales at all, other than being ocean-dwelling mammals. Rather, they are close kin to dolphins. While it was believed that they were a single species, recent research indicates that they may, in fact, be comprised of several different species of Orca. You can find them in every ocean in the world, though they tend to favor the colder waters around Antarctica and the North Atlantic or Pacific. The only predator they possess is humankind. While theres a deadly standoff between the two species, Orcas proliferate in the wild, and have an incredible life span. The males usually live as long as sixty or seventy years, while the females—who are excluded from the sometimes-violent competition for mates—may live a hundred years or more in the wild.

虽名虎鲸，但不同于海洋其他哺乳动物，非鲸目，海豚科的近亲。此前一直认为虎鲸只有一种，但最近的调查显示虎鲸种类繁多。部分虎鲸会终年停留于南极、大西洋北部和太平洋等温度较低的海域，但总体来看，它们的活动范围几乎覆盖全世界水域。它们堪称海上霸王，唯一的天敌也只有人类了。虎鲸全年都可以交配，数量庞大，雄鲸的平均寿命在60到70年左右，野生雌鲸不同于雄鲸经常参与猎杀食物，寿命可达100年甚至更长。

Theyve been observed reaching speeds of around 30 miles per hour, although some Orcas may utilize much greater bursts of speed, based upon their favored prey. Resident pods in the Pacific Northwest have shown a decided preference for salmonids—specifically, Chinook salmon. This presents a conflict with the goals of companies that rely on high yields of salmon for profit. Several communities of killer whale seem to favor beach and ice floe ambush approaches, snatching seals and walruses or even sea birds from their resting places. Others, located in the Southern Hemisphere, take up the challenge of hunting sharks in the open sea, as well as feeding on species of rays and other fish abundant in the cold southern waters.

虎鲸约时速30英里，当然也有爆发力更强的，为了追捕中意的猎物，时速可以更快。太平洋西北海域的虎鲸族群偏爱三文鱼，尤其是大鳞三文鱼。这就和沿岸经营三文鱼生意的公司产生一定的利益冲突。虎鲸族群喜欢在浮冰区伏击猎物，捕杀海豹、海象或者在这里歇脚的海鸟。在南半球海域里，有些虎鲸还会在公海里捕杀鲨鱼，也会以鳐和其他鱼类为食。
