英文作文 篇1
A Rare Fossil Record
The preservation of embryos and juveniles is a rate occurrence in the fossil record. The tiny, delicate skeletons are usually scattered by scavengers or destroyed by weathering before they can be fossilized. Ichthyosaurs had a higher chance of being preserved than did terrestrial creatures because, as marine animals, they tended to live in environments less subject to erosion. Still, their fossilization required a suite of factors: a slow rate of decay of soft tissues, little scavenging by other animals, a lack of swift currents and waves to jumble and carry away small bones, and fairly rapid burial. Given these factors, some areas have become a treasury of well-preserved ichthyosaur fossils.
The deposits at Holzmaden, Germany, present an interesting case for analysis. The ichthyosaur remains are found in black, bituminous marine shales deposited about 190 million years ago. Over the years, thousands of specimens of marine reptiles, fish and invertebrates have been recovered from these rocks. The quality of preservation is outstanding, but what is even more impressive is the number of ichthyosaur fossils containing preserved embryos.
Ichthyosaurs with embryos have been reported from 6 different levels of the shale in a small area around Holzmaden, suggesting that a specific site was used by large numbers of ichthyosaurs repeatedly over time. The embryos are quite advanced in their physical development; their paddles, for example, are already well formed. One specimen is even preserved in the birth canal. In addition, the shale contains the remains of many newborns that are between 20 and 30 inches long.
Why are there so many pregnant females and young at Holzmaden when they are so rare elsewhere? The quality of preservation is almost unmatched and quarry operations have been carried out carefully with an awareness of the value of the fossils. But these factors do not account for the interesting question of how there came to be such a concentration of pregnant ichthyosaurs in a particular place very close to their time of giving birth.

罕见的化石记录 胚胎与幼体被保存下来在化石记录中是少见的事情。微小纤细的骨骼 通常在石化前就被食腐肉的动物拆散了，或者被风化作用破坏掉了。 鱼龙比起陆地的动物 有更大的几率被保存下来，因为它们作为海洋动物常生活在腐蚀性较小的环境中。 但是它们的石化需要一系列因素：软组织的腐烂速度缓慢，很少被其他动物残食，缺少混杂、冲走小骨头的快速水流和波浪，以及相当快地被掩埋。 当这些因素存在时，某些地区就会变成一个充满保存完好的鱼龙化石的宝库。在德国获尔兹梅登，那儿的沉积物给人们提出了一个有趣的分析案例。 人们在黑色的、含沥青的海洋页岩中发现了约 19，000 年前沉积下来的鱼龙化石。 几年时间内，在这些岩石中取得了数以千计的海洋爬行动物、鱼类以及无脊椎动物的标本。 它们的保存质量非常的好，但更令人称奇的是保存下来的育有胚胎的鱼龙化石数目。 在获尔兹梅登附近一个小地区的`六个不同的页岩层中分别发现了育有胚胎的鱼龙化石。 这表明大量的鱼龙经年累月重复使用一个特定的地点。 那些胚胎已经发育得相当完整了。 比如，它们的蹼桨已经完全形成了。 有一个标本甚至被保存在产道中。 而且，那块页岩包含着很多在20 到30 英寸之间的新生幼体的化石。为什么在其他地方那么稀少的怀孕雌兽和幼体在获尔兹梅登却那么多呢?
因为其保存质量几乎举世无双，采集工作的进行一直是一丝不苟的。 大家都认识到这些化石的价值极其珍贵，但这些因素并不能解释这个有趣的问题： 为什么在一个特定的地点会如此集中地出现即将临产的怀孕鱼龙群呢?

英文作文 篇3
Happiness means different things to different people. For example, some students believe that if they have much money or a large number of possessions, they will be happy. They believe that they will be able to do anything they want to if they have money. Some students think that they should be in good health, and enjoy whatever they like. Many students wish to have much wealth from their parents. In this way they don’t have to work hard, and they can have everything. I don’t agree with the above points. We can’t buy many important things with money, such as health, happiness and knowledge.
I value knowledge, which makes me happy, for I can do much for mankind with knowledge. Although different people value happiness differently, my “wealth” of happiness is in my study.
英文作文 篇4
The furthest distance in the world is that when I breathe, I can't find your figure.
The furthest distance in the world is not life and death, but also not separated by numerous hills and streams with friends become strangers. The gap between the heart and the heart, the most difficult time for the poet to overcome the gap.
Once when you said to me, we are best friends; once when we cat in bed talking; when I cry lying in your arms, telling heart grievances; once when we swear this lifetime will be friends forever...... I do not remember, everything has become blurred, as if in yesterday, as if in the distant past.
Remember the day we met, we were all alone, lonely intolerable. A conversation made us start our first contact. Like-minded people, let us become no talk about good friends, then felt like dry desert oasis appeared. Introverted, I began to become lively and cheerful, everywhere I can see busy figure. Friends are more and more, happiness is always around. Heart to heart communication closer to our distance, we often get rid of a lot of friends to hide in the corner, you smiled and said to me, so many good friends, I am your best friend, I like chicken pecking nod: "well, I also like it."
From now on, we are inseparable, attracted the envy of many. Surprisingly, there are contradictions between us, and more and more. I am learning slightly better than you, you always say envy me, let me help you, but I did not say, I will not do the subject, but sometimes you think I don't want to tell you, if you catch me; ZiXiKe, you let me help you cover up reading novels, I have no to help you, you say I'm not a friend. The more and more paradox is that I feel that there is something wrong with our communication.
Remember that day in the examination room, you hinted that I passed the answer to you, but I think we should not resort to deceit, did not do so. After the exam, you ignore me, and I explain to you, you do not listen, say, I heartless. You throw a word to me: "I did not expect you to be such a person, but also friends, what kind of friends you want to use?" Or not good?!" I am confused, I was wrong? Tears are rolling around in my eyes. Is this my friend?
A few days later, you sent a letter to me. In one sentence, I still remember, "we are no longer friends, we have never known each other."." That's over? That's how it all ends? This once so enviable friendship ended like this? I asked myself again and again, "is it me or you that buried this friendship?"
Until today, we meet or turn a blind eye, but you know, every time I pass by the heart will have the slightest pain. Once close, now like passers-by. Although close at hand, but can not communicate, when can we go beyond the distance, and then back to the past? I'm looking forward to it......

新年晚会除夕，我们班开了个晚会，气氛很好。一开始就不同凡俗，有个男生寝室出了个令人大感意外的节目。只见一个叫李新民的.男生“啪”一下关掉了所有的灯，三声“鸡叫声”响彻大厅后。“啪”的一声，大厅又重放光明。然后，该寝室的代表朱国章让我们大家猜一句关于上述情景的诗。他还解释说除了李新民属狗外，其他三人都属鸡。大家都给他们弄愣了。还是班长反应较快，喊道：“雄鸡三唱天下白！”结果全场轰然大笑。然后，他们又出了一个节目，让李新民站在中间，其他三个人围着他每人拜厂120度。要求打一成语。这一次我猜中了：“狗立鸡群！”接着，大家唱歌做游戏，玩到晚上11点多。值班的老大爷来熄灯时，我们才不得不结束晚会而回到各自的寝室。通过这次活动。我发现班上很多同学都是天才歌手！
