秋天,一个丰收的季节。下面是小编整理分享的秋天的世界英语作文,欢迎阅读。希望对大家有所帮助!

Autumn dusk. Long time did not appreciate her love, deep and long. Autumn unique charm, and spring hegemony. Under ancient ink Chunhua Qiuchou month is sustenance. I prefer autumn.

With a heart to feel the pain, eyes flowers wither, Ice cool wind, rain and cold unfeeling.

But I am very happy. Open the windows, pulled out a perfect arc, slowly, and with the fall of the beat, opened his eyes.

In front of the scene almost no change. I saw, not the dream of confusing, do not dream of nada. Opened his eyes in an instant, I felt disillusioned fantasy and handover. Road, gray, for thousands of years do not seem to change; trees are maintained throughout Junzi, I never felt that warm, cars, sparse few, wandering.

However, autumn happens there. She tears it? Do you want people to bridge the depths of her soul scars? The people began to indulge, the rain fall soft atmosphere. All plants begin swaying, you can say looming. Wucaiche pavement like, a little bit of golden gradually spread all over the body it is the leaves! Roadside tree then play again in gold, like the sunset with lake reflection cross-hui India, car? All quiet, this is my autumn! Falling leaves no bleak fall, but fly into the air. Like butterfly ......

Suddenly, they feel cool skateboarding spread to nourish the body from the back of the hand. Ah, autumn, you let me love you in fantasy, but in truth you are tired.

When I looked around again, beheld a pot of chrysanthemum. Stroll vision for so long, finally I found my dream. Cluster, golden, burning in my mind.

Still the same tree, road, car. But I finally saw the autumn. Autumn rhyme is to get a taste of fantasy and realize it. Autumn in the life of fantasy, the fantasy autumn dissolved in the world.

深秋黄昏。好久没领略过她的爱,深远而绵长。秋独具韵味,与春争霸。古人笔墨下春华秋愁,月是寄托。我偏爱秋。

用伤痛的心来感受,眼前百花凋零,风冰冰凉凉,雨冷酷绝情。

可是我现在很快乐。打开窗户,拉出完美的弧,缓缓地,和着秋的节拍,睁开双眼。

眼前的景几乎没有任何变化。我看见的,不是梦境的扑朔迷离,没有梦境的虚无缥缈。在张开眼的瞬间,我感到幻想与幻灭的交接。路,灰的,几千年似乎都不改变;树,自始至终都保持着军姿,那温暖我再没感觉到,车,稀疏的几辆,徘徘徊。

可是,秋雨偏偏出现了。是她流泪了吗?她是否要弥合人们心灵深处的伤痕?整个人开始沉醉,沦陷在雨中柔和的气氛。所有的花草开始摇曳,可以说若隐若现。路面象五彩池,一点一点的金黄逐渐铺遍了它全身,是枯叶!然后路旁的树又在挥金,像夕阳余晖与湖的倒影交相辉印,车呢?一切静谧,这才是我的秋!枯叶并没凄凉的坠落飘零,而是纷飞向空中。似枯叶蝶……

突然,凉凉滑滑的滋养的感觉从手背蔓延至全身。啊,秋雨,你让我在幻想中爱你,又在真实中厌你。

当我再次放眼望去,瞅见一盆菊花。视野漫步如此之久,终于找到了我的梦。一簇,金黄,燃烧在我脑海。

依旧是不变的树、路、车。但是我终于看见了秋。秋的韵是要幻想与悟才领略得到。生活中的秋处在幻想中里,幻想中的秋溶在世界中。

篇18:经典英语作文:秋天叶子为什么会变颜色

全文共 3154 字

+ 加入清单

Why do leaves change color in the fall? asks Patricia Brown, of New York City.

Autumns cool days are trimmed with deep blue skies and golden light, and brilliant leaves of yellow, orange and red. Leaves changing color in the fall are a trees way of preparing for long winter, rather like we put up storm windows and pull warm clothes and blankets out of storage.

In summer, the leaves on trees like pin oaks and sugar maples are green because they are chock-full of the green pigment chlorophyll.

Trees need sunlight to produce chlorophyll. In turn, chlorophyll uses sunlights energy to split water (H2O) into hydrogen and oxygen. Meanwhile, leaves also absorb carbon dioxide gas from the air. The end products of leaf chemistry: carbohydrates (homemade plant food for the tree), and oxygen, released into the air (the gas we need to breathe). The whole process is called photosynthesis.

Along with green chlorophyll, most leaves also contain yellow, orange and red-orange pigments celled carotenoids. Trees dont need light to make carotenoids. Botanists call them "helper pigments," because carotenoids absorb some sunlight and (nicely) pass the energy along to chlorophyll. We dont see much of these deputy pigments (carotene, lycopene, and xanthophyll) in summer, because they are masked by abundant green chlorophyll.

But the ever-shortening days of fall mean less daylight and colder weather. The average tree is rushing to save all the nutrients it can for its winter hibernation. Nitrogen and phosphorus are pulled from leaves for storage in branches. A layer of corky cells grows between the leaves stems and their branches, reducing the leaves supply of nutrients and water.

With diminished sunlight, water, and nutrients, chlorophyll synthesis slows. Old, worn-out chlorophyll breaks down at the usual rate--ironically, sunlight destroys it--so each leafs stock gradually dwindles. And as the green fades, yellow and orange emerge from hiding.

Unlike the green and yellow pigments, red and purple pigments (anthocyanins, part of the flavonoid class) actually form in leaves in the autumn, tinting leaves scarlet and burgundy.

Botanists have long wondered why some trees are genetically programmed to manufacture anthocyanins in the fall. New research indicates that anthocyanins may be a trees own sunscreen.

Anthocyanins are made in a leafs sugary sap, with the help of lots of sun and cool temperatures. Botanists think that anthocyanins shield the leaves fading photosynthesis factories from too much sunlight, rather like the pigment melanin protects our skin from the sun. While the red pigments act as a shield, the tree feverishly breaks down and pulls nutrients out of leaves and into its limbs and trunk before leaves drop or die.

Anthocyanins may also act like Vitamin C or E, scavenging so-called "free radicals" before they can do oxidizing damage to a fall leafs fragile structure.

Upper and outer leaves tend to be reddest, since they are most exposed to sunlight and cold. In some trees, like sugar maples, the reds of the anthocyanins combined with the yellows of the carotenoids make especially brilliant orange leaves.
