相貌古怪名不吉利

　海洋中长相古怪的生物，很多看上去都很可怕，但是“翻车鱼”却笨拙而滑稽。这种学名是“Mola mola”的生物，在各地有不同的称呼，多半是因为它们古怪的外形和有趣的习性。在拉丁语里Mola是“石墨”的意思，于是性。在拉丁语里Mola是“石墨”的意思，于是西班牙人把它称为“石墨鱼”，因为它们的身体表面总有太多寄生虫，变得好像岩石一样粗糙，再加上滚圆形状，好像石墨一样。翻车鱼古怪的习性之一是喜欢侧身躺在海面上，由于它们的身体表面会附着很多发光微生物，在夜间微微散发光芒，于是法国人叫它“月光鱼”，在白天，月亮变成了太阳，于是英语里它就是“太阳鱼”。

　日本人称之为“曼波鱼”，是因为它们在海面上游泳的姿势好像在跳曼波舞。中国人把它称为翻车鱼或者翻车豚，似乎觉得这样滑稽的体格在海洋里难以保持平衡，而且它们总是侧翻在海面，不过有些地区觉得“翻车”和“翻船”一样不太吉利，又开始给它起名叫“车轮鱼”。如果捕捉到车轮鱼需立即放生，亚洲部分地区的渔民们相信钓到车轮鱼已经是行衰运，如果不信邪不放生，用来食用的话，便会随时撞邪，很可能会赔上性命！

　当然，有的地方不信邪。日本和中国台湾的人们都很喜欢食用翻车鱼，尽管它们骨多肉少，也谈不上格外鲜美。翻车鱼别名众多，体现出它的分布广泛，除了北极圈之外几乎在全球所有海域都能找到它们。这是海洋里多骨鱼中最重的鱼，能长到3～4米长，重达2000～2500公斤。它们的身体异常扁平，高甚于宽，身体好像被削掉了一半似的，全身只有前半部，鱼尾就看不到了。一般鱼游动时靠尾鳍摆动，翻车鱼只能依靠强劲的背鳍和臀鳍。

　目前而言，人类对翻车鱼知之甚少，它们的很多习性现在看来还是谜。随着目前海洋中水母的数量有上升趋势，科学家更急切希望揭开翻车鱼身上的秘密，因为翻车鱼是现有海洋生态系统里的水母嗜食者。

　性情温驯的生长冠军

　翻车鱼最喜欢的食物是月形水母，它们也吃小型浮游生物、甲壳类以及小型鱼类，它们的饮食习惯随着成长会慢慢改变，不过要保持壮硕的身材，需要吃很多东西。早在20世纪30年代，美国自然史博物馆的鱼类学家古格就曾对翻车鱼进行过研究，并宣称巨大的翻车鱼是动物界的生长冠军。它们的幼鱼仅有 0.25厘米长，而长到成年鱼时可达3米长，体重比幼鱼时增加了6000万倍。

　1908年9月，澳大利亚悉尼的1艘渔船捕获1尾特别大的翻车鱼，体长3.3米，背鳍与臀鳍的鳍端间距达4.2米，体重约2235公斤，是迄今已知的世界硬骨鱼类体重之最。卵生鱼类产出成熟鱼卵的数量及其质量是该鱼世代繁衍的基础。据称已观测到1尾体长仅1.4米的雌翻车鱼的卵巢中有3亿粒鱼卵，但相应其卵径估计仅1～2毫米，由此估算的怀卵重量与鱼体重量不甚协调，故推测此鱼卵的统计数字有偏高之嫌。目前已知鱼类怀卵量与体长大致呈正相关，因此，可以期望体型更大的翻车鱼的怀卵量可能达到如此巨大的数量。

　翻车鱼虽然能远距离迁徙，但是游泳的速度并不快，因此常常被海洋中其他鱼类、海兽吃掉。此外它们的性情非常温驯，不会主动攻击人类和其他海洋生物，“人善被欺”，自然成为被袭击对象。翻车鱼成鱼将身体压缩到仅剩头胸部，并以厚度可达76毫米的皮肤将自身严严实实地包裹起来，可能是世界上皮肤最厚、自身包裹最严的鱼类，这也是它为了自身安全而采取的防御策略。虽然一般的海洋生物都奈何不了它，只得悻悻离去，但翻车鱼仍会遭到少数凶猛动物的攻击，如海狮、鲨和鲸等进攻性大型海洋动物。

谁能给我一篇有关自信的小故事.最好是英语的.

　为了提高同学们英语口语能力，教师们往往会拿世界名人的演讲稿进行示范教学。下面是我为你整理的几篇英语有趣的故事演讲5分钟，哟。

　a few years ago, i felt like i was stuck in a rut, so i decided to follow in the footsteps of the great american philosopher, morgan spurlock, and try something new for 30 days. the idea is actually pretty simple. think about something you?ve always wanted to add to your life and try it for the next 30 days. it turns out, 30 days is just about the right amount of time to add a new habit or subtract a habit ? like watching the news ? from your life.

　几年前， 我感觉对老一套感到枯燥乏味， 所以我决定追随伟大的美国哲学家摩根?斯普尔洛克的脚步，尝试做新事情30天。这个想法的确是非常简单。考虑下，你常想在你生命中做的一些事情 接下来30天尝试做这些。 这就是，30天刚好是这么一段合适的时间 去养成一个新的习惯或者改掉一个习惯?例如看新闻?在你生活中。

　there?s a few things i learned while doing these 30-day challenges. the first was, instead of the months flying by, forgotten, the time was much more memorable. this was part of a challenge i did to take a picture everyday for a month. and i remember exactly where i was and what i was doing that day. i also noticed that as i started to do more and harder 30-day challenges, my self-confidence grew. i went from desk-dwelling computer nerd to the kind of guy who bikes to work ? for fun. even last year, i ended up hiking up mt. kilimanjaro, the highest mountain in africa. i would never have been that adventurous before i started my 30-day challenges.

　当我在30天做这些挑战性事情时，我学到以下一些事。第一件事是，取代了飞逝而过易被遗忘的岁月的是 这段时间非常的更加令人难忘。挑战的一部分是要一个月内每天我要去拍摄一张照片。我清楚地记得那一天我所处的位置我都在干什么。我也注意到随着我开始做更多的，更难的30天里具有挑战性的事时，我自信心也增强了。我从一个台式计算机宅男极客变成了一个爱骑自行车去工作的人?为了玩乐。甚至去年，我完成了在非洲最高山峰乞力马扎罗山的远足。在我开始这30天做挑战性的事之前我从来没有这样热爱冒险过。

　i also figured out that if you really want something badly enough, you can do anything for 30 days. have you ever wanted to write a novel? every november, tens of thousands of people try to write their own 50,000 word novel from scratch in 30 days. it turns out, all you have to do is write 1,667 words a day for a month. so i did. by the way, the secret is not to go to sleep until you?ve written your words for the day. you might be sleep-deprived, but you?ll finish your novel. now is my book the next great american novel? no. i wrote it in a month. it?s awful. but for the rest of my life, if i meet john hodgman at a ted party, i don?t have to say, ?i?m a computer scientist.? no, no, if i want to i can say, ?i?m a novelist.?

　我也认识到如果你真想一些槽糕透顶的事，你可以在30天里做这些事。你曾想写小说吗?每年11月，数以万计的人们在30天里，从零起点尝试写他们自己的5万字小说。这结果就是，你所要去做的事就是每天写1667个字要写一个月。所以我做到了。顺便说一下，秘密在于除非在一天里你已经写完了1667个字，要不你就甭想睡觉。你可能被剥夺睡眠，但你将会完成你的小说。那么我写的书会是下一部伟大的美国小说吗?不是的。我在一个月内写完它。它看上去太可怕了。但在我的余生，如果我在一个ted聚会上遇见约翰?霍奇曼，我不必开口说，?我是一个电脑科学家。?不，不会的，如果我愿意我可以说，?我是一个小说家。?

　(laughter)

　(笑声)

　so here?s one last thing i?d like to mention. i learned that when i made small, sustainable changes, things i could keep doing, they were more likely to stick. there?s nothing wrong with big, crazy challenges. in fact, they?re a ton of fun. but they?re less likely to stick. when i gave up sugar for 30 days, day 31 looked like this.

　我这儿想提的最后一件事。当我做些小的、持续性的变化，我可以不断尝试做的事时，我学到我可以把它们更容易地坚持做下来。这和又大又疯狂的具有挑战性的事情无关。事实上，它们的乐趣无穷。但是，它们就不太可能坚持做下来。当我在30天里拒绝吃糖果，31天后看上去就像这样。

　(laughter)

　(笑声)

　so here?s my question to you: what are you waiting for? i guarantee you the next 30 days are going to pass whether you like it or not, so why not think about something you have always wanted to try and give it a shot for the next 30 days.

　所以我给大家提的问题是：大家还在等什么呀?我保准大家在未来的30天定会经历你喜欢或者不喜欢的事，那么为什么不考虑一些你常想做的尝试并在未来30天里试试给自己一个机会。

　thanks.

　谢谢。

　good morning, ladies and gentlemen. i?d like to share my teaching dream with you. but before that, i want to say something about the beginning of this dream. in march this year, three teachers from australia came to our school. during the meeting, we exchanged a lot about education. i found that though we have almost the same teaching philosophy, we have different routines. what impressed me most was that their schools end at 3:00 in the afternoon and have no night classes. i can?t tell which kind of routine is better, but the sharp contrast made me think about a better education. the following is a dreamy school in my mind, in which there is no pressure but pleasure.

　in this school, the buildings are well designed, close to nature. in the morning, children can read while enjoying the beautiful sunrise. in the evening, they can exercise by the lake reflecting the amazing sunset. in the spring, they can go to the wild, lie on the lawn, and watch the kite flying in the blue sky. in the summer, they can go to the forest, live in a cabin, and listen to the rhythm of the rain. ?

　students are free but polite and they respect each other. they can leave at 4:00 every afternoon, or perhaps earlier. they have the freedom to organize time. they can go to the library, go to the lab, the computer rooms or the playground. they?re self-motivated and have a strong thirst for knowledge. and there are no frequent exams and rankings. students won?t be forced to wear uniforms everyday, and there is no required hair style. everyday is so colorful that they are looking forward to the next day when going to bed at night,

　every teacher in this school can give a course as they like. there is no tedious rating, no scraps of quantitative management and no rigid standard. teachers can fully display their personality in class, and they feel very happy and content to teach. every morning, on thoughts of giving lessons, they are excited. after class, they are delighted , with smiles on their faces. some experts, scholars and masters are also visiting teachers in this school.yang zhenning can give physics classes for a day. yi zhongtian opens lectures on chinese culture for a week. speaking of music, we can ask wang lihong to give music lectures, just as he did in oxford university. if necessary, we can also invite david beckham to speak something about the world cup ?

　today, as people live a better life, they chase for more enjoyment. we can see from the news that when the holiday comes, there are so many people gather in the scenery site. people like to travel today, they can take a plane, take the bus or even take a bike. on my opinion, the best way to travel is by train. first, it is very cheap. compare with other ways, such as plane and bus, train is less expensive, people can save a lot of money. besides, taking the train is much safer. people don?t have to worry about crush, which is more happen in the plane or bus. second, we can enjoy the scenery in the train. though the train is very slow, we can have a good sight of the beautiful scenery, when we go to tibet, we can see different colors and different mountains during the trip. taking the train is the best way to travel.

　the principal of the school focuses on education rather than waste time in endless meetings and social activities. teachers? wages are not high but enough to live comfortably. there are no other things to do except to teach. there are no paper requirements, no titles and no ranks because they don?t need to be judged by those things. almost every teacher is a well-known scholar and master in a particular field. a language teacher may be a writer at the same time. a math teacher may try to overcome a world-class guess. a physics teacher can win invention awards and a music teacher may return from an international music competition again.

　in short, in this school, the principal is satisfied, the teachers are happy and the students are joyful. that?s my dream.

霍金的故事

科学家霍金小时候的学习能力似乎并不强，他很晚才学会阅读，上学后在班级里的成绩从来没有进过前10名，而 且因为作业总是“很不整洁”，老师们觉得他已经“无可救药”了，同学们也把他当成了嘲弄的对象。在霍金12岁时，他班上有两个男孩子用一袋糖果打赌，说他 永远不能成材，同学们还带有讽刺意味地给他起了个外号叫“爱因斯坦”。谁知，20多年后，当年毫不出众的小男孩真的成了物理界一位大师级人物。这究竟是什 么原因呢？

原来，随着年龄渐长，小霍金对万事万物如何运行开始感兴趣起来，他经常把东西拆散以追根究底，但在把它们恢复组装回去时，他 却束手无策，不过，他的父母并没有因此而责罚他，他的父亲甚至给他担任起数学和物理学“教练”。在十三四岁时，霍金发现自己对物理学方面的研究非常有兴 趣，虽然中学物理学太容易太浅显，显得特别枯燥，但他认为这是最基础的科学，有望解决人们从何处来和为何在这里的问题。从此，霍金开始了真正的科学探索。
