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.

罕見的化石記錄 胚胎與幼體被保存下來在化石記錄中是少見的事情。微小纖細的骨骼 通常在石化前就被食腐肉的動物拆散了，或者被風化作用破壞掉了。 魚龍比起陸地的動物 有更大的幾率被保存下來，因為它們作為海洋動物常生活在腐蝕性較小的環境中。 但是它們的石化需要一系列因素：軟組織的腐爛速度緩慢，很少被其他動物殘食，缺少混雜、沖走小骨頭的快速水流和波浪，以及相當快地被掩埋。 當這些因素存在時，某些地區就會變成一個充滿保存完好的魚龍化石的寶庫。在德國獲爾茲梅登，那兒的沉積物給人們提出了一個有趣的分析案例。 人們在黑色的、含瀝青的海洋頁巖中發現了約 19，000 年前沉積下來的魚龍化石。 幾年時間內，在這些巖石中取得了數以千計的海洋爬行動物、魚類以及無脊椎動物的標本。 它們的保存質量非常的好，但更令人稱奇的是保存下來的育有胚胎的魚龍化石數目。 在獲爾茲梅登附近一個小地區的`六個不同的頁巖層中分別發現了育有胚胎的魚龍化石。 這表明大量的魚龍經年累月重復使用一個特定的地點。 那些胚胎已經發育得相當完整了。 比如，它們的蹼槳已經完全形成了。 有一個標本甚至被保存在產道中。 而且，那塊頁巖包含著很多在20 到30 英寸之間的新生幼體的化石。為什么在其他地方那么稀少的懷孕雌獸和幼體在獲爾茲梅登卻那么多呢?
因為其保存質量幾乎舉世無雙，采集工作的進行一直是一絲不茍的。 大家都認識到這些化石的價值極其珍貴，但這些因素并不能解釋這個有趣的問題： 為什么在一個特定的地點會如此集中地出現即將臨產的懷孕魚龍群呢?

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......

新年晚會除夕，我們班開了個晚會，氣氛很好。一開始就不同凡俗，有個男生寢室出了個令人大感意外的節目。只見一個叫李新民的.男生“啪”一下關掉了所有的燈，三聲“雞叫聲”響徹大廳后。“啪”的一聲，大廳又重放光明。然后，該寢室的代表朱國章讓我們大家猜一句關于上述情景的詩。他還解釋說除了李新民屬狗外，其他三人都屬雞。大家都給他們弄愣了。還是班長反應較快，喊道：“雄雞三唱天下白！”結果全場轟然大笑。然后，他們又出了一個節目，讓李新民站在中間，其他三個人圍著他每人拜廠120度。要求打一成語。這一次我猜中了：“狗立雞群！”接著，大家唱歌做游戲，玩到晚上11點多。值班的老大爺來熄燈時，我們才不得不結束晚會而回到各自的寢室。通過這次活動。我發現班上很多同學都是天才歌手！
