我每天六点起床、洗脸刷牙后，就开始复习功课，七点钟我就去上学。

再过几天就是端午节了。

你知道端午节的有来吗?我知道，为了纪念伍子廉，他的父兄被楚王所杀，之后他去吴国挖墓，楚王知道了他赐剑死了他将尸体投入大江，这天5月5日端午节的习俗是个家插艾草，石榴花，蒜头，划龙舟。

我最喜欢过端午节了!

“保护动物”这四个字我们每天都在说，可是又有多少人在用实际行动表示呢？被割掉胸鳍和尾鳍的鲨鱼，被割掉角的犀牛，用洁白的象牙制作的装饰品，活熊取胆……这一件件残忍的事情时常发生，申赋渔的《逝者如渡渡》叙说了数百年间，世界各地灭绝了的或正在走向灭绝的30多种动物的故事，如：日本象。指猴。象龟。渡渡鸟……它们都是人类的伙伴，它们也曾快乐的生活在这个地球上，可是，因为人类掠夺了它们的生存空间，使它们从地球上永远消失了。

全球变暖，使北极熊赖以生存的浮冰断裂。消融。也使他们的食物——海象。海豹逐渐减少，使北极熊频临灭绝；人口迅速膨胀和乱砍乱伐，使熊猫的生存范围被迫向竹子稀少的山顶推进，食不果腹成了家常便饭，当竹子开花时，有些野生熊猫会因找不到食物而饿死。熊猫虽是我国的“国宝”，可在全世界的数量也不过区区20--多只。

人类啊！醒悟吧，让“保护动物”不只是说说而已。动物是人类的朋友，是地球大家庭中的一员，动物同人类生活在同一个地球上，动物作为食物链中的一员，如果动物灭绝了，那么人类也逃脱不了灭绝的厄运。

动物是有灵性的，它们也有思维和感情，人类怎么能忍心去杀害它们呢？每一个物种的消失，都是人类走向孤独的脚步，没有了动物的陪伴，人类还能走多远？保护动物绝不仅仅是一个组织的责任，大自然为大家所共有，保护动物，人人有责。但愿每个人都问一下自己，自己的行为曾经给地球带来过怎样的伤痛？自己有没有为一时的利益而透支我们的未来？

I am a student in Huaxing Middle School. Do you know the plastic bags? Do you often use the plastic bags? I don’t like them. I think they use the wasting valuable oil their production. And they can’t decompose(分解) in a short time. The plastic bags will make our world worse. I agree with the rule, which people can’t get the free plastic bags in the shops, supermarkets. It encourages people to use their cloth bags and baskets. It’s good for our environment.

So I hope all the students in our class stop to use the plastic bags, and use our own cloth bags. I hope we can take care of our environment.

Let’s make our world more and more beautiful.

Dear Miss Zhu,

亲爱的周老师，

How time flies! It has been a few years since I left high school, but I still remember you in my heart, because you’re the best teacher in my mind. It’s not only because you taught me knowledge, but also you taught me how to study. I have really benefitted a lot from you. So I would like to express my great thanks to you, and share my life in college with you.

时间飞逝!我高中毕业已经几年了，但我仍然把你记在我的心里，因为你是我心目中最好的老师。这不仅是因为你教与我知识，而且你还教我如何学习。从你身上我真的获益匪浅。所以我想向你表达我的感谢，并与你分享我的大学生活。

Now I’m studying in Hunan First Normal College, which is Chairman Mao’s former school. I major in English, because I find it so fun and interesting. As far as I’m concerned, our English Department is the best department in our college. The teachers in our department are knowledgeable, experienced, and warm-hearted. And my classmates are nice, friendly and helpful. Thus, I have a good atmosphere to study. When I have difficulties in study, I always ask my teachers for help or discuss with my classmates. Through their help, I have made great progress in my English study.

我现在在湖南第一师范学校学习，这是主席之前呆过的学校。我的专业是英语，因为我觉得它很有趣。我觉得我们英语系是我校最好的学部。我们系的老师知识渊博，经验丰富，热心肠。我的同学们也很和蔼，友好，乐于助人。因此，我拥有一个很好的学习氛围。当我在学习上遇到困难时，我总是向我的老师寻求帮助或与同学讨论。在他们的帮助下，我在英语学习上取得了很大的进步。

College life is much different from high school life. In college, we should acquire knowledge as well as improve our integrated abilities. There are a lot of English classes for us to learn, such as Basic English, Oral English, Listening, Reading, Writing, Translation, Grammar, English Literature, and so on. I enjoy these classes very much. Except English, we have many other subjects to learn. Life seems so busy here but it’s so fruitful for me.

大学生活与高中生活有很大的不同。在大学，我们要获取知识也要提高我们的综合能力。我们要上很多的英语课，比如，基础英语，英语口语，听力阅读，写作，翻译，语法，英语文学等。我非常喜欢这些课。除英语外，我们还要学习很多其他科目。在这里生活是如此的忙碌，但这对我来说是如此丰硕的收获。

After class, I usually go to the English Corner. There I can practice my oral English by talking with foreigners or chatting with my schoolmates. Now, I’m able to communicate with foreigners well. Sometimes I also take part in some social activities. For instance, last weekend I attended an interesting play. As it was my first performance, I felt a little nervous at the beginning. But when I appeared on the stage, I made every audience laugh happily. I was so proud of myself at that moment, because this was my first achievement.

下课后，我经常去英语角。在那里我可以通过与外国人或我的同学聊天来练习我的英语口语。现在我可以很好的和外国人交流了。有时候我也可以参加一些社交活动。例如，上周我参加了一个有趣的表演。因为是我第一次表演，所以一开始的时候我觉得有点紧张。但当我出现在舞台上时，我让每一个观众都开心的笑了。在那一刻，我为我自己感到骄傲，因为这是我的第一个收获。

I have a bad behavior, when I get angry, I will fight back and say the bad words which will hurt other people. Once my friend Lucy missed the time we had ordered, she was late for half an hour, when she arrive, I got angry and said I did not want to see her again. Two days later, Lucy explained and I felt so sorry to her, I must learn to control my bad temper.

[我的坏脾气英语作文翻译

有许多人因为能挣钱就随便捕捉青蛙，青蛙体大肉肥，味道鲜美而且还非常有营养，就有人到市场上卖，我感到非常痛心，我也无能为力，只好默默的为青蛙祝福。

青蛙被称为“除害高手”青蛙的又叫田鸡，蛙类大约有4800种，绝大部分生活在水中，也有生活在雨林潮湿环境的树上的。卵产于水中，青蛙是卵生的，卵孵化成蝌蚪，蝌蚪在水里也能捉害虫，等的卵都在水里，一只蝌蚪每天要吃掉100多只孑孓，最后才变成青蛙。它可以捕捉害虫，蚊子、苍蝇、小飞蛾、蝗虫、蝼蛄、椿象、蝇类及稻飞虱等农业害虫为主要食物。都可以吃。在南方有许多人捕捉青蛙，在北方就少一些。一只青蛙一分钟能吃10只，一只青蛙一天捕食的害虫，少则五六十只，多则二百只，如此推算，一只青蛙一年至少要吃掉15000只。因此，青蛙是当之无愧的农田卫士。

保护我们的“除害高手”——青蛙吧！

It was sunny and very hot today。 I got up early and helped my parents cook breakfast。 Then I washed the dishes and cleaned the room。 After a short rest I did my homework in the morning。 In the afternoon I went swimming in the nearest swimming pool with my friends。 It was really cool to swim in such a hot day。 I surfed the internet and read a storybook in the evening。 I really had a busy and interesting day。翻译：这天天气晴朗比较热。 我起得很早，帮我的父母做早饭。然后我洗碗打扫屋子。休息一会后我上午做作业。 下午我和朋友去我家最近的游泳池游泳。 在如此炎热的夏天游泳的确很棒。 晚上我上网、看故事书。我这天很忙过得很搞笑。

“There is only one earth”,I hope everyone will protect our environment well. Thanks!

[英语作文保护环境人人有责

我们要保护小动物，特别是小鸡这类弱小的动物，因为小鸡早晨可以叫我们起床，可以生一个又一个圆圆的的鸡蛋，还可以提供鸡肉给我们吃。

We need to protect the small animal, especially this kind of small animal chicken, because chicken morning to wake us up, can have a round egg, can also provide for us to eat chicken.

有一次，我和妈妈上菜市场，听见一位老奶奶在喊：“卖鸡了，今天的鸡又肥又嫩!”妈妈说：“今天，我们买一只鸡回家，炖汤喝。”我说：“好吧。”可又想了想：如果我们吃了鸡，那么就吃不到鸡蛋了，就对妈妈说：“不行，吃了鸡就没有鸡蛋吃了。”“傻孩子，你瞎操什么心啊!”妈妈不由分说地把我拉到卖鸡的那边。卖鸡的老奶奶正在杀鸡，只见她拔下鸡脖子上的毛，拿刀用力地在鸡脖子上划了几下。血喷向了四周，鸡挣扎了几下就死了。“太残忍了，我不要吃鸡!”我向妈妈大声的抗议。“好吧，不买了，我们就去买点蔬菜吧。”也许妈妈也觉得残忍，就同意了。

One time, my mother and I heard the food market, an old woman shouted: "chicken, chicken fat and tender today!" Mother said: "today, we bought a chicken soup to drink at home." I said: "OK." But think again: if we eat chicken, so cant eat the egg, the mother said: "no, not eat chicken egg to eat." "Silly boy, what do you care ah!" Mother allowing no explanation to put me into the chicken. The old woman was a chicken, she pulled out the hair on the neck, a knife in the neck with a few strokes under. Blood sprayed around chicken, struggled and died. "So cruel, I dont eat chicken!" I asked my mother loudly protested. "Well, do not buy, we went to buy some vegetables." Maybe mom was cruel, also agreed.

假如我们的生活中没有了动物，世界就会变得很孤独。我们要保护动物，从自身做起：少吃肉类食品，少穿皮衣毛衣;看见别人欺负动物，要勇敢地站出来劝说他们。

If we live without the animal, the world will become very lonely. We must protect the animal, start from their own: eat less meat, less wear fur sweaters; see others bully animal, we should stand up to persuade them.

保护动物，人人有责!

Animal protection, everyones responsibility!

环境保护

Nowadays, peoples life has changed a lot with the development of modern technology and economy, which has put lots of negative effects on the environment.

Why this? Because, firstly, some factories are pouring wastes into rivers, lakes, seas and so forth; secondly, because of human activities, a great number of plants and animals are losing their lives; thirdly, using modern machines and chemicals is bad for the environment. Besides these, there are a lot of human activities which have done or are doing harm to our surroundings.

For this, I think, first, our government should make drastic measures to regulate human activities; second, we human beings should take pains-taking work to stop ourselves destroying the environment and try our best to protect our living space more.

难忘的回忆

Last summer holiday, I learned to swim. It was very unforgettable and interesting. I went to the swimming pool with my father. He taught me how to swim. At first, I was afraid of diving in the water. And I felt uncomfortable in the water. But father said it doesn’t matter and he would protect me. Then I began to swim, but I couldn’t swim forward at all. It made me upset. Then father told me how to move, how to stretch out my hands and legs. Slowly, I could move a little. In fact, it was not that easy. I learned it for almost half a month. I was excited when father told me I made it.

这篇内容是关于回忆的初中英语作文，讲述的是暑假去学游泳，我和爸爸去游泳池，他叫我怎么游的故事。

When the Arctic Ocean freezes over in the autumn, polar bears set off in search of their favorite meals: fatty ringed seals and bearded seals. By the summer, the sea ice begins to melt and break apart. Deprived of access to the tasty seals, polar bears spend the summer fasting. At least, thats whats supposed to happen. As the planet warms, the warmer ice-free season is getting longer and longer. So whats a hungry bear to do?

Scientists once thought that polar bears might survive by supplementing their pinniped diet by turning to terrestrial foods like snow geese, their eggs and caribou.

"Weve had this debate in the literature about whether terrestrial foods are nutritionally relevant to polar bears during the on-land season when the ice has melted."

University of Alberta biologist Nick Pilfold.

"And weve known for a long time, going back to research in the early 70s, even going to back to early explorer logs, that polar bears will consume terrestrial based foods. But the debate was always whether those foods actually add up, energetically." In other words, do these substitutes provide enough nutrition to make up for the lost seals?

To find out, Pilfold and his colleagues estimated the weight lost each day by polar bears in the wilds of western Hudson Bay during the ice-free season, when they could ostensibly be chowing down on terrestrial foods. Then they compared that to the weight lost by bears that are temporarily held in Manitobas Polar Bear Alert Program.

While captive, the bears do not eat. They drop about one kilogram each day. But the wild bears, who had access to the Arctic snack bar, lost the same amount of weight each day. The results are in the journal Physiological and Biochemical Zoology.

"Which is really saying that the terrestrial foods do not have dense enough energy to offset the mass loss. So this idea that bears can just switch from eating sea ice–based food to land food and thats going to help supplement against longer ice-free seasons, that really doesnt show up in the data."

The problem is that polar bears evolved to rely on the marine diet.

"The food on land is protein and carbohydrate based, and the food the polar bears really focus on is fat. Fat is the name of the game for these bears; theyre highly adapted to absorbing that fat into their system and putting it onto their body as body mass, so they can fast on it later on. And the only thing thats going to provide them with that type of fat are marine mammals. And they can only access those marine mammals when theres sea ice."

Adult males can go eight months without food. But younger, sub-adult bears, which are no longer nursing and must hunt, cant last as long without sea ice. So as the Arctic warms, younger polar bears will disproportionately die out. Leaving the species survival in doubt.

北冰洋在秋季结冰以后，北极熊就会出发去寻求它们最喜欢的食物：富含脂肪的海豹和胡子海豹。海冰在夏季开始融化断裂。这使北极熊在夏季无法吃到美味的海豹，所以它们进入禁食期。至少，情况应该是这样。但是由于地球变暖，温暖的无冰季节越来越长。那饥饿的北极熊要怎么办?

科学家曾经认为，北极熊可能会转向陆地上的食物来补充它们对鳍足类动物饮食的需求，进而生存下去，这些陆地食物包括雪雁、雪雁蛋和北美驯鹿。

“文献中有过这类辩论，即在寒冷融化时陆地食物是否能满足北极熊的营养需求。”

尼克·皮尔福德是加拿大阿尔伯塔大学的生物学家。

“通过上世纪70年代初的研究，还有早期的探险者日志，我们很早以前就知道，北极熊会以陆地食物为食。但是辩论的焦点在于，这些食物是否能增加北极熊的能量。”换句话说，这些替代食物能否为北极熊提供足够的营养，弥补不能进食海豹带来的损失?

为了解开这个疑惑，皮尔福德及同事对西哈德逊湾荒野地区的北极熊在无冰季期间每天失掉的体重进行了估算，从表面上看，北极熊在这段时间食用了陆地食物。随后，他们将这一数据与通过马尼托巴北极熊预警计划暂时捕得的北极熊所失掉的体重进行了对比。

在被关期间，北极熊不吃东西。它们的体重每天大约下降1公斤。虽然野生北极熊能享用北极“小吃”，但是它们的体重每天也同样会下降1公斤。这一研究结果发表在《生理学和生化动物学》期刊上。

“显然结果表明，陆地食物不能为北极熊提供足以抵消大量损失的能量。所以，北极熊可以从食用海冰下面的食物转向食用陆地食物，并帮助它们对抗日益延长的无冰季这个观点，并没有在这项数据中得到证明。”

问题是，北极熊进化成了依靠海洋食物的动物。

“陆地食物以蛋白质和碳水化合物为基础，而北极熊需要的食物以脂肪为主。脂肪是这些熊真正需要的东西;它们高度适应的情况是，将脂肪吸收进它们的系统中，然后把这些脂肪放在身上以增加体重，这样它们之后就可以依靠这些脂肪来度过禁食期。唯一能提供给北极熊这种脂肪的就是海洋哺乳动物。但是它们只能在有海冰时食用到这些海洋哺乳动物。”

成年北极熊可以8个月不进食。但是小一些的未成年北极熊已经不再被哺育，它们必须要去猎食，可是它们不能在漫长的无冰季期间一直不进食。所以，随着北极地区变暖，较小的北极熊将会大批死亡。这使这些物种的生存成为问题。
