　　英語作文美文美句摘抄1

From the window of my room, I could see a tall cotton-rose hibiscus. In spring, when green foliage was half hidden by mist, the tree looked very enchanting dotted with red blossom. This inspiring neighbor of mine often set my mind working. I gradually regarded it as my best friend.

從我的房間的窗子向外望去，可以看到一株高大的芙蓉樹。春日里，芙蓉樹在薄霧中若隱若現，紅花點點，樣子實在迷人。它總是賦予我靈感，讓我思如泉涌。時間久了，我竟把這菱蓉視為知已了。

Nevertheless, when I opened the window one morning, to my amazement, the tree was almost bare beyond recognition as a result of the storm ravages the night before. Struck by the plight, I was seized with a sadness at the thought “all the blossom is doomed to fall”. I could not help sighing with emotion: the course of life never runs smooth, for there are so many ups and downs, twists and turns. The vicissitudes of my life saw my beloved friends parting one after another. Isn’t it similar to the tree shedding its flowers in the wind?

然而，一天清晨，當我推開窗子時，愕然發現前夜的一場風雨已將它摧殘得落紅滿地。剎那間，我有一種"花開終有落"的悲涼感覺。這使我不由得發出一聲慨嘆：人生的旅途中，總是少不了種種羈絆，那些曲折的經歷總會伴隨著我們。曾經失去過的摯愛的朋友，生命的脆弱不正是像這隨風而逝的花嗎？

This event faded from my memory as time went by. One day after I came home from the countryside, I found the room stuffy and casually opened the window. Something outside caught my eye and dazzled me. It was a plum tree all scarlet with blossom set off beautifully by the sunset. The surprise discovery overwhelmed me with pleasure. I wondered why I had no idea of some unyielding life sprouting over the fallen petals when I was grieving for the hibiscus.

隨著時間的流逝，我漸漸地把那天的感觸淡忘了，一次出差回來，感到屋內的空氣有些沉悶，于是我不經意的打開了窗，可就在那一瞬，我被眼前的景象驚呆了。窗外，一株李子樹開花了，火紅火紅的花朵，滿樹都是。在夕陽的映襯下，分外美麗。這意外讓我驚喜不已。沒想到當初自己只顧悲傷，卻沒發現那凄涼的背后，竟存在著如此堅強的靈魂。

When the last withered petal dropped, all the joyful admiration for the hibiscus sank into oblivion as if nothing was left, until the landscape was again ablaze with the red plum blossom to remind people of life’s alternation and continuance. Can’t it be said that life is actually a symphony, a harmonious composition of loss and gain.

是啊，當芙蓉的最后一片花瓣凋落之時，人們以往對它的贊許都已成為過眼去煙。可如今，李子樹卻成長起來了，那火紅的花兒正向人們昭示著生命的更迭與繁衍。誰能否認生命原本就是一場得失共存的交響音呢？

Standing by the window lost in thought for a long time, I realized that no scenery in the world remains unchanged. As long as you keep your heart basking in the sun, every dawn will present a fine prospect for you to unfold and the world will always be about new hopes.

我久久地佇立在窗前，深深感悟到，生命之中本沒有一成不變的風景，只要你的心永遠向著陽光，那么每一個清晨就會向你展現出一個等待著由你來開啟的美景。不管你正經歷著怎樣的風雨，請相信，這個世界總會帶給你新的希望。

　　英語作文美文美句摘抄2

Those in a serious relationship have long been warned about the dangers of the seven-year itch. But research has found couples risk running into trouble far earlier-thanks to the seven-month slouch。

已婚男女要警惕“七年之癢”說法由來已久。但一項調查發現，情侶之間出現問題的時間要遠遠早于七年，這就是“七月之癢”。

This is the point at which we stop trying quite so hard to impress our new love and start revealing all the bad habits that have so far remained hidden。 當兩人在一起相處了七個月之后，雙方不再像剛開始那樣努力想給對方留下好印象，而開始“原形畢露”。

These can include unsavoury bodily functions such as breaking wind in front of an other half, nose picking or letting armpits go unshaven. Before the milestone, most couples enjoy an extended honeymoon period where both go out of their way to keep well-groomed and observe good manners。 比如，當著對方的面放屁、挖鼻子，或不刮腋毛。而在此之前，很多情侶都處于熱戀期，兩人都用心地裝扮自己，努力在對方面前保持好的形象。

However, it seems once a couple has been together for around seven months they decide they really do love each other and start to let go。 然而，似乎兩人在一起到了七個月左右時，他們就會覺得彼此的感情已經穩定，便開始放任自流。

According to a survey of 1,000 adults, the seven-month point is when couples are most likely to think it acceptable to stop paying attention to details such as shaving regularly and keeping nails trimmed while also putting their bad habits on display。

一項對1000名成年人開展的調查顯示，情侶們在一起到了七個月時，便開始覺得可以不再注意定期刮毛和修指甲這樣的細節問題，而且還會漸漸暴露出自己的壞習慣。

More than nine in ten women and almost as many men admit that they let themselves go once they are in the full throes of a romance。 90%以上的女性承認，一旦感情穩定下來，她們便開始放松自己。相同比例的男性也是如此。

However it seems men are far happier to relax their standards while more women told researchers from Remington that they never allow themselves to be seen looking hairy or too unkempt。 然而據雷明頓調查人員的調查，男性似乎更容易放松自己的標準，較多的女性稱她們從不會讓自己看起來頭發凌亂或邋里邋遢。

More than half of all adults said they make a special effort at the start of a relationship。 超過一半的人說他們在剛開始談戀愛時都特別注意這些問題。

Once life with their other half becomes more routine, 48 per cent said they start breaking winnd in front of their partner, 68 per cent will skip sexy clothes for unflattering outfits round the house and 58 per cent walk around naked。 而一旦與另一半的感情穩定下來，48%的人會開始當著對方的面放屁，68%的人不再追求性感的衣著，而是穿得非常隨便，58%的人會光著身子在屋里走來走去。

Only 6 per cent said they would never let their partner see them be so uncouth。 只有6%的人說他們永遠不會在伴侶面前表現得如此放肆。

There are also still some traditionalists out there, with 13 per cent saying they believe revealing bad habits is only acceptable after marriage。 調查對象中不乏一些傳統人士，13%的人認為只有在結婚之后才可以放松一點。

When we come in the human world will never be destined to face human interaction, with the years of gradual but more and more mature.

Sophisticated or not a persons age are not just, perhaps too many are referring to awareness of emotions and grasp the extent of emotion.

The three conditions in life: affection, friendship, love. Perhaps these three emotions, the only love in life, the interpretation of a more exciting and rich. Affection and friendship it is a relationship between groups, but also can be a relationship between monomer. Only the doomed love between two people are emotional, but are only different from the affection and friendship, which only exist in the heterosexual feelings.

Love, there is no wrong, love is what everybody has a right to a free, a kind of instinct, a private affair, no one can hinder. Because love is a kind of emotional depth, is also a kind of emotional touch with the initiation. Love is diverse, and are multiple choice, we can have a love, love can also choose a. We can love any one person, whether some people love themselves, but also may refuse to love any one person, no matter how other people love their own.

Love is a kind of consciousness and emotion, perhaps the first love, did not go too much about whether you win some and lose. It is undeniable that, regardless of the outcome of Department愛之深what, who can deny this love that feeling of it really?

Love is a spiritual and emotional depths of the edge of real experience, and this feeling of human Forever is a very sweet, very touching. Walking in the human world, in the face from the side with the vision of the vast flow of people walked in, people can really love, but for the love and infatuated and also how much? So falling in love with a person is a happy thing, and get other peoples love is also a lucky thing.

Love, there was no mistake! Although the face of reality, too many secular, ethical, moral, false imprisonment and regullations of the interpretation of love. But if we want to cool one, this is a responsible love and protection. Love because love and cherish are required, as there is no rules, how can draw a perfect circle it?

Love never is an indulgence, indulgent love with the true depth of less degree, this might love Forever is not the true meaning of love and nature.

Two unfamiliar people originally came together because of love, it is not easy, because it is required of each others true feelings and trust to pay in order to form the true love. Which is due to the existence of love in between, but also the most vulnerable to injuries, but also very fragile, so it should be better cherish and protect the love of primary colors, rather than its loss.

Love, has never been wrong! Love is a very real emotion and soul of that pulsating!

Love is a kind of icing on the cake of life, true love is a distillation of the precipitate after. Forever love because henme are emotional, it is doomed to love is not a harm, nor is it an incomplete. Whether because of their love and love, that is another matter.

As we often say: edge in man-made, were in an act of God, we should not contend with Gods arrangements. Sometimes more in need of love is a natural formation, rather than contributing to allocate Miller. Because love has its growth and a sophisticated process slowly.

Love does not have a gain or loss because of the nature and positioning of love. To have this love, it is happiness, even if the loss, but also learn to calm. Regardless of gain and loss, are we to deny their love, the beauty that the feeling of it? Are we on the negation of their love is true or it?

當我們降臨在人世間，從此便注定將面對人與人交往，隨著歲月的漸進而走向成熟。

一個人的成熟與否不是僅僅是年齡，或許過多的是指認識情感與把握情感的深淺程度。

人生三大情：親情、友情、愛情。或許這三大情感之中，唯有愛情在人生之中，演繹得更精彩與豐富。親情與友情它是一個群體關系，也可以是一種單體關系。而唯有愛情注定是兩個人之間的情感，而且是唯一區別于親情與友情的，它只存在于異性之間的情感。

愛，是沒有錯的，愛是一個人人都擁有的權利，一種自由，一種本能，一種私事，任何人都不能阻礙。因為愛是一種情感的深化，也是一種情感的觸動與萌生。愛是多樣的，而且是多重的選擇，我們可以擁有一種愛，也可以選擇一種愛。我們可以愛任何一個人，無論別人是否愛自己，也可拒絕任何一個人的愛，無論別人如何愛自己。

愛是一種意識與情感，或許最初的愛意，原本沒有過多的去計較是否有得有失。不可否認的是，愛之深處無論結局是什么，誰能否定這愛之情感的那份真切呢？

愛是一種心靈深處與情感邊緣的真切體驗，而這種感覺對人永遠是很甜美，也很動人。行走在人世間，面對從身邊與視野里走過的茫茫人流，能真正讓人去愛，而且為這愛而癡情的又有多少呢？所以愛上一個人是一件幸福的事，而得到別人的愛也是一種幸運的事。

愛，原本沒有錯！雖然面對現實，太多的世俗、倫理、道德、法規禁錮著愛的演繹。但如果我們冷靜一想，這是對愛的一種負責與保護。因為愛是需要呵護與珍惜的，正如沒有規矩，如何能畫出一個完美的圓呢？

愛決不是一種放縱，放縱的愛少了深度與真度，這樣的愛或許永遠不是愛的真諦與本質。

兩個原本陌生的人因愛走到了一起，就很不容易，因為那是需要彼此的真情與信任的付出，才能形成這份真愛的。而這愛因存在于兩者之間，也最容易受傷，也很脆弱，所以就應更好的珍惜與保護這愛的原色，而不讓其丟失。

愛，從來就沒有錯！愛是一種情感的真切與靈魂的那份悸動！

愛是一種生活的錦上添花，愛是一份真情升華后的沉淀。因為愛永遠是恒美的情感，也就注定愛不是一種傷害，也不是一種殘缺。能否因愛而擁有其愛，那是另一回事。

正如我們常說：緣在人為，份在天意，我們不能與上帝的安排抗衡。有時的愛更需要的是一種自然形成，而非撥苗助長。因為愛有其成長與成熟的一個慢慢過程。

愛并不是因為擁有得失而定位愛的本性的。能擁有這份愛，那是幸福，就算失落，也要學會坦然。無論得與失，難道我們就否定其愛的過程中，那份美麗的感覺嗎？難道我們就該否定其愛的真假嗎？

Yiyang distance to go now for a month, even if it still can not find their own satisfaction that four days to record your feelings accompanied me time, perhaps rough speech, because of you, in my mind it is the most beautiful story. I said give all of you the next chapter.

Understanding your first 41 days, I swore off all sensible idea, put on a single word to make my sincere letter, the selection of a gift wrapped my deep tenderness, embarked on a train destined for Yiyang , duty-bound in love for the first time chose to be wearing armor of the brave. You probably never know, paranoid view of love in my modesty and pride, but I met you, we are all collapse if there is another new self. You bring me the beam of light, so clever, just shines into my heart the most cold corner. Since then, a red-hot.

April 2, after a long shaking all night and drink a few saliva, ear snoring after another sleepless night endured torture, finally arrived, a small platform to usher in the warmth of your eyes, my heart full of grievances, than this city I imagine the more desolate. "Tired?" You ask me, did not answer, silently holding your hand, rely on the power of your body, walking in this strange city, although tired but the end result of you are so relieved.

That morning, I resist the full is sleepy, listening to tell you miss lightly in my ear, along with "I love you" in the name, and you wear a necklace for me personally, a love one and not the same, has long been clear, I feel I should be long past the age sweet captured, but that moment still feel happy mess.

距離去益陽已經一個月了，哪怕還是找不到自己滿意的情愫來記錄那四天你我相伴的時光，言語也許粗糙，因為有你，在我心中卻是最華麗的故事。我說過未來的篇章盡數為你。

認識你第41天的時候，我拋卻所有理智的想法，帶上了一封一字一句道盡我真誠的信，挑選了一份包裹我濃濃柔情的禮物，踏上了去往益陽的火車，在愛情里第一次義無反顧選擇了做個身披鎧甲的勇者。你大抵從來不會知道，愛情觀里我偏執矜持和驕傲，可是遇見你，所有都瓦解，好像出現了另一個全新的自己。你帶給我的那束光芒，那么巧，剛好照進我內心最冰涼的角落。此后，一片熾熱。

4月2號，經過漫長的搖晃，整晚喝了幾口水，一夜無眠忍受著耳邊鼾聲此起彼伏的折磨，終于抵達，狹小的站臺迎來你溫情的目光，我的心滿腹委屈，這個城市比我想象的更荒涼。“累嗎？”你問我，沒有回答，靜默地挽著你的手，倚靠著你身上的力量，走在這個陌生的城市，雖疲憊但終因有你所以都釋然。

那天早上，我抵御著滿滿地困意，聽著你在我耳邊輕言地訴說想念，伴隨著“我愛你”三個字，還有你親手為我戴上的項鏈，愛情里一招一式不盡相同，早已了然，我覺得自己應該早已過了被甜言蜜語俘獲的年齡階段，可那一刻仍覺得幸福得一塌糊涂。總想做個特別的女子，總想經歷和擁有非凡的愛情情節，然而當心產生悸動時，突然發現那些最簡樸的感動足以蕩氣回腸。

四月份，總是多雨的季節。初來乍到的陌生讓我們只能徘徊在街頭漫無目的地閑晃，大部分的時間被用來百無聊賴地行走，沒有風光無限，沒有特色小吃，就連所謂的繁華一條街也遠遠“超出了”我的期待，實在累了便找個地方隨意點些吃的坐下來休憩，我們甚至還跑去網吧，你玩游戲，我睡覺。超乎尋常的平淡，有疲倦，會抱怨，可是我們彼此十指相扣，我亦深深的滿足。陪伴著，幫你挑選衣服的顏色，為你參考鞋子的款式，一起討論食宿的地點，細雨朦朧中你為我撐起的傘，寒意席卷時為我披上的外衣，波瀾不驚的溫暖撫平了我內心對這個城市殘存的失望。

假期稍縱即逝，終究迎來分別，沒有絲毫的傷感，我們都各自恬靜地笑著，道句再見，我異常堅強地頭也不回，豁然走進檢票口，待猛然轉身，你的臉龐早已被阻隔在我的視線之外。想念頃刻泛濫決堤！

過去我曾無數次憧憬未來我會遇見怎樣的人，發生什么樣的故事，你偏離了我最初所有的幻想，可是沒有遺憾。真愛大抵就是無法自拔地愛上一個與自己擇偶標準反差極大的人！經過了多少繞指的情長才成就了這份心滿意足的邂逅，多么幸運，最后，是你！

An important new industry, oil refining, grew after the Civil war. Crude oil, or petroleum – a dark, thick ooze from the earth – had been known for hundreds of years, but little use had ever been made of it. In the 1850’s Samuel M. Kier, a manufacturer in western Pennsylvania, began collecting the oil from local seepages and refining it into kerosene. Refining, like smelting, is a process of removing impurities from a raw material.

Kerosene was used to light lamps. It was a cheap substitute for whale oil, which was becoming harder to get. Soon there was a large demand for kerosene. People began to search for new supplies of petroleum.

The first oil well was drilled by E.L. Drake, a retired railroad conductor. In 1859 he began drilling in Titusville, Pennsylvania. The whole venture seemed so impractical and foolish that onlookers called it “ Drake’s Folly”. But when he had drilled down about 70 feet(21 meters), Drake struck oil. His well began to yield 20 barrels of crude oil a day.

News of Drake’s success brought oil prospectors to the scene. By the early 1860’s these wildcatters were drilling for “ black gold” all over western Pennsylvania. The boom rivaled the California gold rush of 1848 in its excitement and Wild West atmosphere. And it brought far more wealth to the prospectors than any gold rush.

Crude oil could be refined into many products. For some years kerosene continued to be the principal one. It was sold in grocery stores and door-to-door. In the 1880’s refiners learned how to make other petroleum products such as waxes and lubricating oils. Petroleum was not then used to make gasoline or heating oil.

一種重要的新興工業——煉油業在國內戰爭后成長起來。未加工的石油，或原油——種深色的地下的稠漿——數百年來一直為大眾所知，但是人們卻很少使用過它。

在十九世紀五十年代，薩繆爾·M·科爾，賓西法尼亞西部的一位制造商，開始從當地的溢出物中收集石油，并將它煉成煤油。與冶煉礦石一樣，石油提煉是一個從未加工的原料中除去雜質的過程。煤油被用來點燈。

它是鯨油的一種便宜的替代品，而鯨油正變得越來越難以獲得。不久就產生了對煤油的大量需求。人們開始尋找新的石油供應。第一口油井為E·L·瑞克，一個退休的火車檢票員所鉆得。1859年他開始在賓西法尼亞的泰特斯維爾鉆井。整個的這項冒險事業看起來是如此不現實和愚蠢以致旁觀者稱之為"鴨子的蠢行"。（譯者注：DrakesFolly，drake在這里意含雙關，即指瑞克的名字，又指該詞的本義即鴨子。）但當瑞克往下鉆至70英尺（21米）的時候，他發現了石油。他的油井從此每天生產20桶原油。瑞克成功的消息將石油勘探者們吸引到現場。截止到19世紀60年代早期，這些冒險者為尋找"黑色的金子"鉆探遍了整個賓西法尼亞西部。這項繁榮的事業在刺激性和粗獷的西部氣氛上可與1848年的加州淘金熱相媲美，而且它為勘探者帶來了遠超過淘金潮的財富。原油能被提煉成許多產品。多年以來煤油一直是主要的一種產品。

它在雜貨店中出售由人挨戶推銷。19世紀八十九十年代煉油者們懂得了生產其它石油產品，如蠟和潤滑油。那時石油還沒有被用來制造汽油或采暖裝置用油。

In the oysters were raised in much the same way as dirt farmers raised tomatoes- by transplanting them. First, farmers selected the oyster bed, cleared the bottom of old shells and other debris, then scattered clean shells about. Next, they ”planted” fertilized oyster eggs, which within two or three weeks hatched into larvae. The larvae drifted until they attached themselves to the clean shells on the bottom. There they remained and in time grew into baby oysters called seed or spat. The spat grew larger by drawing in seawater from which they derived microscopic particles of food. Before long, farmers gathered the baby oysters, transplanted them once more into another body of water to fatten them up.

Until recently the supply of wild oysters and those crudely farmed were more than enough to satisfy people’s needs. But today the delectable seafood is no longer available in abundance. The problem has become so serious that some oyster beds have vanished entirely.

Fortunately, as far back as the early 1900’s marine biologists realized that if new measures were not taken, oysters would become extinct or at best a luxury food. So they set up well-equipped hatcheries and went to work. But they did not have the proper equipment or the skill to handle the eggs. They did not know when, what, and how to feed the larvae. And they knew little about the predators that attack and eat baby oysters by the millions. They failed, but they doggedly kept at it. Finally, in the 1940’s a significant breakthrough was made.

The marine biologists discovered that by raising the temperature of the water, they could induce oysters to spawn not only in the summer but also in the fall, winter, and spring. Later they developed a technique for feeding the larvae and rearing them to spat. Going still further, they succeeded in breeding new strains that were resistant to diseases, grew faster and larger, and flourished in water of different salinities and temperatures. In addition, the cultivated oysters tasted better!

過去人們飼養牡蠣的方式很大程度上類似于田地里的農夫種植蕃茄——通過移植來飼養它們。

首先，農夫選好牡蠣苗床，清除底部的舊殼和其它雜物，然后四處撒播干凈的殼。接著，他們"栽種"已受精的牡蠣卵。這些卵在2～3周內會孵化成幼貝。

幼貝一直漂流直到粘在苗床底部干凈的殼上為止。它們會呆在那兒并逐漸長成小牡蠣。我們稱之為種子或貝苗。貝苗吸進海水中的微小生物作為食物從而越長越大。不久之后，農夫將這些小牡蠣收集起來，把它們移種進其他的水域加快其生長，然后再次將它們移種進另外的水域以使其肥壯起來。直到最近，野生的以及人工飼養的牡蠣完全能夠滿足人們的需要。

但是今天這種可口的海味已不再大量存在。這個問題已經變得如此嚴重以至于一些牡蠣苗床已完全消失。幸運的是，早在20世紀初期海洋生物學家們就意識到如果不采取新的措施，牡蠣將會滅絕或至少會變為一種奢侈的食品。因此他們建造了裝備良好的孵卵場所并開始工作。但是他們尚沒有適當的裝置或技術來處理牡蠣卵。他們不知道何時、用什么以及如何喂養幼貝。他們對捕食數百萬幼小牡蠣的動物天敵也所知無幾。

他們失敗了，但他們頑強地堅持了下來。終于，在20世紀40年代，一個重要的突破性的進展產生了。海洋生物學家發現，升高水溫能夠誘導牡蠣不僅在夏季也在秋季、冬季和春季里產卵。后來他們發展了一項技術來喂養幼貝至其長成貝苗。

他們進一步成功地培養出了新的品種，可以抵抗疾病、長得更快、更大并且在不同的`鹽度和溫度的水中都能茁壯生長。此外，這些培殖出的牡蠣口感更佳！

The theory of plate tectonics describes the motions of the lithosphere, the comparatively rigid outer layer of the Earth that includes all the crust and part of the underlying mantle. The lithosphere(n.[地]巖石圈)is divided into a few dozen plates of various sizes and shapes, in general the plates are in motion with respect to one another. A mid-ocean ridge is a boundary between plates where new lithospheric material is injected from below. As the plates diverge from a mid-ocean ridge they slide on a more yielding layer at the base of the lithosphere.

Since the size of the Earth is essentially constant, new lithosphere can be created at the mid-ocean ridges only if an equal amount of lithospheric material is consumed elsewhere. The site of this destruction is another kind of plate boundary: a subduction zone. There one plate dives under the edge of another and is reincorporated into the mantle. Both kinds of plate boundary are associated with fault systems, earthquakes and volcanism, but the kinds of geologic activity observed at the two boundaries are quite different.

The idea of sea-floor spreading actually preceded the theory of plate tectonics. In its original version, in the early 1960’s, it described the creation and destruction of the ocean floor, but it did not specify rigid lithospheric plates. The hypothesis was substantiated soon afterward by the discovery that periodic reversals of the Earth’s magnetic field are recorded in the oceanic crust. As magma rises under the mid-ocean ridge, ferromagnetic minerals in the magma become magnetized in the direction of the magma become magnetized in the direction of the geomagnetic field. When the magma cools and solidifies, the direction and the polarity of the field are preserved in the magnetized volcanic rock. Reversals of the field give rise to a series of magnetic stripes running parallel to the axis of the rift. The oceanic crust thus serves as a magnetic tape recording of the history of the geomagnetic field that can be dated independently; the width of the stripes indicates the rate of the sea-floor spreading.

板塊結構理論描述巖石圈的運動。巖石圈是相對堅硬的地球外層，包括全部地殼和部分地幔。

巖石圈被劃分為幾十個大小不同形狀各異的板塊，一般而言這些板塊都處于相對運動之中。一道中海脊是板塊之間的邊界，在那里新的巖石圈的物質從下部注入。

當板塊從中海脊脫離時，它們滑向在巖石圈基部較易變形的地層上。因為地球的大小本質上是不變的，只有同等數量的巖石圈物質在其它地方被吞沒，新的巖石圈才能生成。銷毀舊巖石圈的地方形成另外一種板塊邊界：一塊潛沒的區域。在這里，一塊板塊潛沒到另一板塊的邊緣之下并結合入地幔之中。

兩種板塊邊界均與地層系統、地震以及火山活動有關，但在兩種邊界處觀察到的諸般地質活動卻迥然不同。海床擴展說實際上早于板塊結構理論。在20世紀60年代它的理論雛形中，描述了海底的生成和毀滅，但沒有詳細介紹堅硬的巖石圈板塊。這個假定不久之后為發現所證實。

該發現表明地球磁場周期性的逆轉被記錄在海洋地殼中。當巖漿從中海脊下涌起的時候，巖漿中的磁鐵礦物質按地磁場的方向被磁化。巖漿冷卻并凝固下來后，地磁場的方向和磁極被保留在磁化了的火山巖中。磁場的逆轉形成一系列與斷層軸線平行的條形磁區。

這樣海洋殼就扮演了磁帶的角色，記錄下可以鑒定時間的地磁場的歷史。條形磁區的寬度表明了海底擴展的速度。

Life comes in a package. This package includes happiness andsorrow, failure and success, hope and despair.人生好似一個包裹，這個包裹里藏著快樂與悲傷、成功與失敗，希望與絕望。

Failure is the path to success. It helps us to touch the sky, teaches us to survive and shows us aspecific way. Success brings in money, fame, pride and self-respect. Here it becomes veryimportant to keep our head on out shoulder. The only way to show our gratitude to God forbestowing success on us is by being humble, modest, courteous and respectful to the lessfortunate ones.

失敗是成功之母。它讓我們觸及藍天，它教會我們如何生存，它給予我們一條特殊的路。成功給予我們金錢、名譽、驕傲和自尊。這里，保持頭腦清醒便顯得尤為重要。唯一能讓我們感激上帝給予的成功便是始終卑微、謙虛、禮貌并且尊重沒有我們幸運的人們。

這個星期六他們見面時"到那時"覺察到"如果"的心情不是很好。像往常一樣，他們坐在特意預留給他們的餐桌上點餐。剛一點完"到那時"就問道:如果，你怎么了?你看起來好像不太高興。"

IF looked at WHEN and replied,

"Im not sure, I just dont feel like I am making any progress. Thislast week I saw a course I wanted to take if only I had the time to take it."

"如果"看了看"到那時"答道"我也不知道怎么了，只是覺得自己沒什么進步。上個星期我發現一個很好的課程，如果有時間的話，我就去學。"

WHEN knew exactly how IF felt. "Yeah," replied WHEN,"I too saw a course and I am going toregister when I get enough money together." WHEN then said,"well what about that new job youwere going to apply for. You were so excited about it last week, did you apply?"

"到那時"非常理解"如果"的感受。他答道是啊，我也看到一項課程，等到錢充足的時候，我就去報名。對了，你打算申請的新工作怎么樣了？上星期見你說得那么情緒激昂，申請了嗎？ "

IF responded,"If my computer didnt break down last week, I would have applied. But, mycomputer is not working, so I could not type my resume."

"如果"回答道"如果不是上周我的電腦壞了，我會申請的。但是它壞了，我無法打印簡歷，所以只能放棄了。"

"Don t worry about it IF, when you are ready another job will come through. I have been thinkingabout looking for another job also, but I will wait and when the weather gets nicer I will look then."WHEN then went on to tell IF about his week, hoping that it would cheer him up a bit.

"別著急，等到你準備好時，另一個工作就出現了。我也一直考慮著換個工作，但是我想等到天氣看起來好一些時再行動。"然后，"到那時"繼續跟"如果"談論著他的星期計劃，希望這樣能使他的朋友高興起來。

The man at the next table couldnt help overhear WHEN and IF. They both were talking aboutwhen this and if that, finally he couldnt take it anymore.

"Excuse me gentlemen," the man said. IFand WHEN both looked at the man and wondered what he wanted. The man continued,

"Imsorry, but I couldnt help hearing your conversation. I think I know how you could solve yourproblems."

鄰桌的一個男人無意中聽到他們的談話。他昕見兩個人一直在說著"等什么什么時候如果這樣那樣"的話，他再也無法忍受了。于是，男人說道"打擾一下，先生們。""如果"和"到那時"吃驚地看著他，不知道他要做什么。男人繼續道很抱歉，我無意中聽到你們的交談。我想我知道如何解決你們的問題。"

IF smiled and thought, how could a complete stranger know how to solve all of their problems. Ifonly he knew. When he realized the challenges they faced there was no way he could solve theirproblems! Curious, IF asked the gentleman,"How do you think you can solve our problems?"

"如果"笑了笑，心想，一個完全陌生的人怎么會知道如何解決他們兩個人生活中的問題呢。如果讓他認識到他們所面對的困難，恐怕他再也不會那樣說了。出于好奇"如果"還是問道你認為應該如何解決我們的問題呢？ "

The gentleman smiled and said ,"You only need listen to yourselves. It reminds me of an oldproverb:

"If and When were planted , and Nothing grew."

男人笑著答道"你們說的話讓我想起一句古老的諺語：只想不做，就會沒有收獲。"

IF and WHEN looked puzzled. The gentleman smiled and said,"Start counting how many timesyou use the words if and when. Rather than thinking if and when, start doing, take action, stoptalking about if and when."

"如果"和"到那時"疑惑地看著他。男人繼續說從現在開始，數一下你們用了多少次？如果和？到那時這兩個詞語。你們不要總是思考？如果怎樣怎樣到那時怎樣怎樣而是應該著手去做，采取行動，請不要再談論如果和到那時。"

IF and WHEN both looked surprised, and suddenly realized that what the gentleman had said wasso true. Both of them were guilty of thinking,acting and living their life for the "ifs and whens, Thegentleman left and IF and WHENs conversation changed. They made a pact that when they metfor lunch next week, there would be no "ifs and whens"; they would only talk about what theyaccomplished!

"如果"和"到那時"感到十分驚訝，他們突然意識到這個男人說得很正確。兩個人都為自己把思想、行為、生活的希望放在"如果和到那時"上感到慚愧。男人離開后，他們談話的內容有了改變。他們約定下個星期一起吃午餐時，再也沒有"如果"和"到那時他們只會談論已經完成的事情。

　　英語作文美文美句摘抄10

It was New Years night .An aged man was standing at awindow. He raised his mournful eyes towards the deep blue sky,where the stars were floating like white lilies on the surface of aclear calm lake. When he cast them on the earth where fewmore hopeless people than himself now moved towards theircertain goal-the tomb. He had already passed sixty of the stagesleading to it, and he had brought from his journey nothing but errors and remorse. Now his healthwas poor, his mind vacant, his heart sorrowful, and his old age short of comforts.

這是新年的夜晚一位老人站在窗邊，憂傷的眼睛眺望著深藍的天空空中的繁星，猶如漂浮在清澈如鏡的湖面上的朵朵百合。他慢慢將目光投向地面。此刻，沒有什么人比他還絕望。他即將邁向他最終的歸宿——墳墓。他已走過通向墳墓的六十級臺階，除了錯誤和悔恨，他一無所獲。現在他體弱多病，精神空虛，心哀神傷，人到晚年卻無所慰藉。

The days of his youth appeared like dream before him, and he recalled the serious moment whenhis father placed him at the entrances of the two roads One leading to a peaceful, sunny placecovered with flowers, fruits and resounding with soft, sweet songs; the other leading to a deepdark cave which was endless, where poison flowed instead of water and where devils and poisonsnakes hissed and crawled.

年輕歲月，如夢般展現在他面前，老人想起父親把他帶到岔路口的那個莊嚴時刻。一條路通向安寧、快樂的世界，鮮花遇布，果實豐碩，甜美輕柔的歌聲在空中回蕩；另一條路則通向幽深黑暗，沒有盡頭的洞，洞內流淌著的不是水而是毒液，群魔亂舞，毒蛇嘶嘶爬動。

He looked towards the sky and cried painfully,"0h youth, return! Oh, my father, place me oncemore at the entrance to life and III chose the better way!

"But both his father and the days of hisyouth had passed away.

他仰望星空，痛苦地大喊：“啊，青春，回來吧！啊，父親，再一次帶我到人生的岔路口吧，我會選一條更好的道路。”但是，他的父親和他的青春歲月都已一去不復返了。

He saw the lights flowing away in the darkness, and these were the days of his wasted life; he saw astar fall from the sky and disappeared, and this was the symbol of himself .His remorse which waslike a sharp arrow struck deeply into his heart. Then he remembered his friends in his childhood,which entered life together with him. But they had made their way to success and were nowhonored and happy on this New Years night.

他看到燈光在黑暗中流逝，就像他揮霍掉的往昔；他看到一顆流星自天邊墜落，消失不見，就像是他的化身。無盡的悔恨，像一支利箭，深刺心間。他又記起和自己一同邁入人生之途的兒時玩伴，j但他們已功成名就，在這個新年之夜，倍受尊崇，幸福快樂。

The clock in the high church tower struck and the sound made him remember his parents earlylove for him. They had taught him and prayed to God for his good. But he chose the wrong waywith shame and grief he dared no longer to look towards the heaven where his father lived. Hisdarkened eyes were full of tears, and with a despairing effort. He burst out a cry:"Come back, myearly days! Come back! "

高高的教堂鐘樓傳來鐘聲，這聲音使他記起父母早年對他的疼愛：他們教育他，為他祈禱。然而，他卻選擇了錯誤的道路：羞愧和悲哀使他再也沒有勇氣仰望父親所在的天堂：黯淡的雙眼溢滿了淚水，他絕望地嘶聲大呼：“回來吧，我的往昔！回來吧！”
