鲨鱼早在恐龙出现前三亿年前就已经存在地球上，至今已超过四亿年，它们在近一亿年来几乎没有改变。
鲨鱼，在古代叫作鲛、鲛鲨、沙鱼，是海洋中的庞然大物，所以号称“海中狼”。
鲨鱼，被一些人认为是海洋中最凶猛的动物。鲸鲨以小型海洋生物为食物，和须鲸差不多。由于食物具有某种相似性，经过漫长的生物演化，它们长得和须鲸很有相似点，这个大白鲨叫做“趋同进化”。于是“鲸鲨”的名字就理所当然了。当然，鲸鲨是现存鲨鱼中最大的，也是已知鱼类中最大的。鲨鱼需要保护，我们餐桌上香喷喷的鱼翅汤就是鲨鱼的背鳍做的，一旦被割去了背鳍鲨鱼就会因为失去平衡能力沉到海底饿死。
世界上约有380种鲨鱼。约有30种会主动攻击人，有7种可能会致人死亡，还有27种因为体型和习性的`关系，具有危险性。
根据化石考察和科学家推算得知，鲨鱼在地上生活了约1.8亿年，它早在3亿多年前就已经存在，至今外形都没有多大改变，说明它的生存能力极强，人称海洋“猎手”。

鲸类是一种生活在水中的哺乳动物，它具有和陆上哺乳动物相同的生理特徵，例如用肺呼吸、胎生等，更具备了一些为适应水生环境所演化出的特殊生理构造。鲸分为3类，分别是须鲸和齿鲸。这两大类的分群，再学术上主要是依据它们摄食方式之不同而定，须鲸主要的形态特徵是没有牙齿，但是有具大的鲸须，可用来筛选浮游生物。所以为滤食性。齿鲸亚目的主要特徵为有牙齿，掠食性，其牙齿的数目与排列方式受到食性的影向会有不同，全世界现存有13科约79种。
鲸鱼虽然有鱼字，其实它并不是鱼类，而是哺乳类动物，它有许多和鱼类极不相同的特性，例如一般鱼类是左右摆动尾鳍来使身体前进，而鲸鱼却是以上下摆动尾鳍的方式前进。它们利用前端的鳍状肢来保持身体平衡及控制力向，有些鲸鱼背部的上端还有能保持身体垂直的鳍呢！
鲸鱼是群集动物，它们通常成群结队的在海裏生活，可是当鲸鱼呼吸时，就需要游到水面上来，这时鲸鱼是利用头上的喷水孔来呼吸，呼气时，空气中的湿气会凝结而形成我们所熟悉的喷泉状。专家们甚至可以从喷水的高度、宽度及角度，来辨识鲸鱼的种类呢！鲸鱼的种类很多，大致分成齿鲸和须鲸两大类。
鲸鱼的表皮下有著极厚的脂肪层，那就是俗称的鲸油，它可以使鲸体保持温暖，而且也能贮存能量以供应不时之需。由於鲸鱼体内拥有许多特殊的构造，使它能够长时间的在水中屏庄呼吸、减慢心跳速度，因此当它沈到海底，总要经过一段长时间后，才会再浮出水面。除了具有贮存氧气的构造外，当身体某个部位需要大量的血液供应时，体内还会有集中供应的特殊机能呢！

A simple dcussion about Up
Pixar Animation Studios a superior about talking story at all times: Toy Story a story about deeply fraternal affection. Finding Nemo a story about a father’s introspection about h education road. The Incredibles a story about middle-aged man and wife’s life cr. Cars a story about moralities in physical education’s world by telling a star’s experiences. Ratatouille a story about a spirit that never gives up and you can realize your dream. Because of those wonderful cartoons, Pixar makes itself become an excellent symbol in cartoon sphere.
Therefore, Up worth being expected. And the truth that it’s a fantastic cartoon. To my mind, dream, commitment and responsibility the key of Up’s successful.
Children’s dreams are the easiest and the most romantic, on account of they always have deeply interest and passion for new things and strange world. But sometimes it’s difficult to realize their dreams by themselves; they usually need adults’ help. And those behaviors are not only their promes, but their commitments and responsibilities.
Russell and Carl’s relationship a key of Up. They have many differences: age, characters and background. And Up explains the relationship between adults and children by them.
Though Carl and Ellie’s love story just a few minutes, it impressive
and affecting. And it’s my favorite part in Up. Every man and wife wants to live a happy life, but true life usually makes it difficult to realize. But it doesn’t mean dream unpractical, prome untrue. Through Carl becomes unsociable and eccentric, he still remember h prome to Ellie. In my opinion, the thing which flies not the house, but a heart which brave and insts on its dream and prome.
And the adventurer, Charles a special role in Up. I think he stands for the people, who just care about their own benefit, totally forget social benefit and their roles in the society. There are so many kinds of dreams, so there are some persons make fame and wealth to be their goals. In fact, it reasonable, but it’s wrong to damage the social benefit. Th way of doing things terrible, shameful and lamentable. In the film, Charles forges sample at first, then kills many innocent men, and tries h best to get the animal, a kind of big bird. Everything he does for h own fame and wealth. The film has hit the right and wrong on the nose. In the final battle, empty-handed Charles fell down into a so deep cliff. It’s not only a punhment to him, but a satire to th kind of people.
Dream likes a check, prome likes an acceptance. Once you prome, you must try your best to make it come true for it your responsibility and duty.

春姑娘踏着轻盈的脚步悄悄地来到了人间。春风吹过，万物复苏。小草宝宝好奇地从地下探出头来；竹子弟弟迫不及待地冲了出来；石榴树哥哥长出了嫩绿的新芽。不久，绵绵的细雨打破了春日的寂静，植物们欢快地喝下这“生命之水”。石榴树的新芽渐渐地长出了浅绿的叶子，竹子不知什么时候抽出了竹叶，一派生机勃勃的景色。
夏哥哥着急地奔向人间。太阳猛烈地照着，粉红的荷花和洁白的茉莉花相互媲美。荷花亭亭玉立，枝茎不停地往上伸，似乎要看美丽的景色，有的含苞欲放，有的还是花骨朵儿呢！茉莉也不甘示弱，它们散发着一阵阵浓郁的清香，吸引来了一群群可爱的小蝴蝶，它们翩翩起舞，像一位位舞者在展示自己的舞姿。
送走了烈日炎炎的夏天，便迎来了金灿灿的秋天。院子里的桂花树开出了一朵朵金黄的花朵，散发着一片诱人的`香味，就算十里远也能闻到。桂花如米粒般大小，要是远看，真不容易被发现呢！石榴树上，火红的果子在绿叶的衬托下，显得更美了，像一个个姑娘害羞了脸。有的神气地抬起头；有的双胞胎紧靠着，似乎在说悄悄话；还有的藏在绿叶里，似乎在跟我们玩捉迷藏呢！
冬天不知不觉地到了，树都落下了金黄的树叶，准备冬眠了。只有那腊梅勇敢地矗立着，开出了一朵朵鹅黄的花朵，幽幽的香气飘来，似有似无，闻起来却神清气爽。天空飘着白蝴蝶似的雪花，给大地铺上了银毯，给树木披上了银装，活像一位位雪人在指引方向。
我爱生机盎然的小院，更爱把它装饰如此美丽的大自然！

前几天，爷爷在市场上买了一只小黑猪，墨黑发亮，爷爷笑呵呵地说：“这只小黑猪是那窝小猪里最大的最肥的，食欲一定会好的。”
刚刚开始，我把刷锅水倒在桶里给它喝，它看也不看我一眼，趴在地上一动不动两只大耳朵盖住眼睛，以为它怕陌生，便走了过去，然后，躲到一棵大樟树后偷偷摸摸的看着它有没有吃，它见我一走，就吧嗒吧嗒的喝起来，不到一分钟，就把我给它的刷锅水喝的一滴都不剩了，我自言自语地说：“哎！这头小黑猪，是我见世界上最会吃的小猪了，真不愧是猪八戒的后代。”
几天后，小黑见我不再陌生了，每天听到奶奶刷锅声就冲到奶奶门口，要起了它那“6”字型的尾巴来问奶奶要吃的。有一次，小黑猪欣掉猪圈的门在偷吃邻居的大白菜，被发现赶了回来，爷爷气坏了一脚踢小黑猪屁股说：“在家里吃的饱饱，又跑到邻居家偷菜吃，中午一定让你饿肚子。”小黑猪好想听懂了爷爷的责骂。回到猪圈里，用大耳朵盖住眼睛，一声不响的趴着。奶奶见它可怜，拿来几片菜叶扔到猪圈，小黑猪见有吃的，把刚才的事全忘光了。
这就是我奶奶家的小黑猪。

Dear Petty,
I am happy to receive your letter and I am glad to hear that you have good days recently. I hope you can keep your happiness all the time. But I am not happy these days, because I feel great pressures. Two weeks ago, I caught a cold and then had a fever. I could do nothing in those days. Therefore, I asked for leave for four days to stay at home. I came back to school until the midterm examination. I was not surprised that I did not do well in the exam. It makes me unhappy. I worked so hard to prepare for it. My parents comfort me that I would be better if I had not been ill. I hope I can recover soon. And I hope you can take good care of yourself.
sincerely yours,
Kate
