秋风和秋雨这对双胞胎经常一起出现。它们悄悄地来到人间，调皮的击打树叶。一片又一片的叶子不堪重负，依依不舍地从大树母亲的身上飘落下来。它们像小船，荡来荡去；它们像摇篮，悠闲的摇啊摇；它们又像蝴蝶，在空中翩翩起舞。秋姑娘来了，给世界染上了五彩的颜色。

秋天是五彩的，而让秋天五彩的一部分——是树叶。

银杏树叶，原来在树上快乐地跳舞，听大树唱歌。披着绿油油的迷彩。可自从秋风和秋雨双胞胎来了以后，他们用手擦掉了银杏树叶上的迷彩。有些树叶不幸被抓住，擦去了迷彩，露出金黄的皮肤。有些虽然被抓住，但仍逃脱了，留下了一半的迷彩。还有些可机灵啦，一看见秋风过来，早就跑没影了。银杏树叶的形状可奇怪了，站起来看像扇子，倒过来看像女生的裙子，横过来看又像蝴蝶的半边翅膀，稀奇古怪。然而，最与众不同的还是它的脉络。其他树叶的脉络是一根主脉，然后伸向四面八方。可银杏树叶的脉络是单独的一根一根，跟别的树叶一点儿也不一样。

枫叶是最能代表秋天的。

远看像爪子，近看还像爪子。叶子从根部开始向上分叉，多为单数（分叉的叶瓣）。脉络清晰。

杀伤力最大的莫过于甜栗子树叶。

边缘有着利齿，其他……一样（与别的树叶）。

啊！树叶让秋天跟美丽。

秋天带着一身金黄，迈着轻盈的脚步悄悄地来到人间。

Autumn, with a golden body, walked with light footsteps quietly came to the world.

草坪上的枫树上飘下几片黄中带红的落叶，像许多小鸟在飞，啊!原来是秋风给落叶长了一双翅膀。

The maple trees on the lawn floated a few yellow leaves with red leaves, like many birds flying! It turned out that the autumn wind had a pair of wings for the fallen leaves.

一群大雁往南飞，它们一会儿拍成“人”字，一会而拍成“一”字。望城坡上的枫树阿姨和柳树婶婶都脱去了绿罩衫;松树爷爷却还穿着绿罩衫;菊花姐姐正迎风开放;地上小草动一块西一块，不像春天那样茂盛，也不像夏天那样碧绿。来望城坡的小朋友都穿上了毛绒衣。

A flock of wild geese fly south, and they are made into "human" characters for a while, and then they are made into "one". The slope of the Wangcheng maple and willow aunt aunt are off the green blouse; pine grandpa was still wearing green blouse; chrysanthemum sister is the wind open ground grass; moving west one piece, like a spring nor summer lush, green. The kids from Wangcheng slope are all wearing plush clothes.

果园里，果实累累，海棠果摇动着它那圆圆的小脸，冲你点头微笑;红艳艳的苹果好像挤在一起的胖娃娃，拔开绿叶，笑咪咪地往外瞧……

In the orchard, fruit, canophyllic shook its round face, you nod and smile; red apples seem crowded together fat baby, unplug the leaves, smiling to see......

望城坡下的山脚是一片金黄的田野，稻谷黄了，像一层金黄色的地毯，农民伯伯擦着汗水，心里想：一年的劳动又有了收获了!

The foot of the Wangcheng slope is a golden field. The rice is yellow. It looks like a golden carpet. The farmers uncle rubs his sweat. He thinks, "one years work has got a harvest again."!

It’s the middle of September now and the autumn has come. The hot days have gone. It’s cool in the morning and at night. It’s more comfortable than ever. But the weather is a little bit dry, so we must drink more water. In the northern part of China, the leaves turn yellow and look beautiful, but in the south, there is little change. I love autumn very much because I like the scenery in the autumn.

现在是九月，秋天已经到来了。天热了。早上和晚上很凉爽。比以往任何时候都更舒适。但是天气有点干燥，所以我们必须多喝水。在中国的北部，树叶变黄了，看起来很漂亮，但在南方，却没有什么变化。我非常喜欢秋天，因为我喜欢秋天的景色。

Summer sister quietly gone, the autumn girl came in a hurry, she did not pay attention to you, the autumn door opened.

Did not expect, Mr. pomegranate actually gave the autumn girl a bag of red pearls, flashing, lit the whole large orchard.

Watching the park is really lively! Colorful chrysanthemum contests, white like snow, yellow tournament gold, pink like Xia ... ... colorful, beautiful! Her posture is also very moving: some Minato together, like a few Good sister in the whisper; some lowered his head, like a shy little girl ... ... is really graceful! Golden yellow sweet-scented osmanthus exudes a refreshing fragrance, really "Osmanthus bloom, fragrant floating ten miles" ah!

This is my eyes beautiful autumn scenery, let us enjoy this charming scenery together!

我最喜欢秋天了，因为秋天的叶子很美。一阵风吹来，树上的叶子飘飘悠悠的，像一只只翩翩起舞的黄蝴蝶。

秋天的叶子，有深绿色的，有黄色的，还有绿中带黄······叶子也各不相同，有扇子形的，有菱形的，有心形的，还有椭圆形的。

其中我最喜欢的是枫叶。绿中透着点红意，是那么富有生命力。枫叶呈龙爪形，正好五片，就像一只小巧玲珑的嘴巴，软软的，可爱极了。他的边缘线还不规则地镶着一圈花边。它的颜色是绿中带红。到了秋天，叶绿素因为气温下降，而渐渐分解，其他色素的颜得以显露出来。除此之外，枫叶中储存的糖分还会分解转变成花青素，使叶片的颜色更加艳红。

还有想小扇子一样的银杏树。上面密密的布满了叶脉，一半绿，一半黄，像是被谁染了颜色。一阵风吹过，枯黄的叶子在空中飘落，犹如一只黄蝴蝶翩翩起舞。在阳光的照耀下，色彩斑斓，那么灵动，那么美妙。

啊!秋天的叶子可真美啊!

Autumn is so beautiful, the autumn wind blowing slightly, issued a small voice, like a little girl in the piano.

Autumn is a bumper season. Fields, corn and wheat are usually put on the usual reluctant to wear "gold clothes", bent down to meet the "autumn girl". In the orchard, the pomegranate cracked his mouth and smiled at the fruit.

Children in the countryside eat sweet and delicious rice and fresh fruits and vegetables, drinking hot chicken soup, heart happy. They finished the meal, happily ran to the mountains, to the mountain picking maple leaves, tree maple leaves like butterflies, moths as "fly" down. The small squirrels are pine cones in the trees and are prepared for winter. Dayan also lined up to fly to the south.

I love about a few good friends to Zhongshan Park put "paper kite". We stood, while the "paper kite" refueling, because we are in the game who put high. The autumn wind blows our "paper kite" high and far away. See the air flying around the colorful "paper kite", like a bird, my heart like filling the honey as sweet. In the park big flower beds, a blossoming blooming chrysanthemum exudes a refreshing aroma, and some like a soft cloud, mix and match; some like butterflies of the golden wings, thin, beautiful and beautiful; there are like colorful fireworks.

This is my favorite, beautiful autumn, bring us all the "gift". I love you, fall.

Autumn, bloom, the fruit mature, in the autumn orchard, the green leaves withered, and my brother Liu Sibo ran out to the grandfather of the orchard, ran into the orchard, we sat on the grass to enjoy the beautiful autumn.

We picked the apple to eat a feeling really sweet.

We continue to enjoy the beautiful autumn. Autumn is colorful, full of the joy of harvest, it is intoxicated.

What is the rain in the autumn? It is not like a thunder in spring, it is not as heavy rain as the summer, it is not as rain and snow as winter. Then what is it in the end it? Let us go together to reveal the mysterious veil of autumn it!

Autumn is softer. Autumn hit in the face, Rou Si, a cool feeling can not help but arises spontaneously. After the rain, the air fresh, you will never bother it.

The rainbow rhythm, the rhythm of the raindrops beat in the filthy car cover, playing a wonderful symphony, a rain, the car turned to spotless, like a new one. Raindrops hit the window glass, the window glass immediately become clear and bright, "vocal" accompanied by "water painting", beautiful. Irritable time, take a look, cool, and trouble immediately thrown into the clouds. Field, raindrops came to the top of the tent, sit on the "slide" jump down, the dust are taken away.

Autumn is air conditioning. Under a few rain, the temperature immediately down, the air is not so hot. Rain, the temperature immediately cool down, if not rain, the summer tail seems to have refused to go the same.

Autumn is stamps, postal cool, small animals who have to save food, and autumn harvest winter, in order to avoid winter cold and cold forced to be frozen.

Autumn is a magnifying glass, it is useful for people to enlarge things, people are eyeful harvest scene.

I like autumn leaves.

Walking in the mountains, I jumped down to running in the woods, this is the world of leaves. The leaves of trees turn yellow. The leaves of trees dancing in the air. Fly ah fly ah, take away the heat in the summer, the autumn is cool and refreshing, also brought the harvest season. I love autumn the leaves of trees.

I continue to go forward, a leaf falling from my eyes, so I am curious to catch it. Leaf is the size of a slap, veins many, I dont see what it is the leaves of the tree, had to smell the smell. An apple scent rushed into the nose and Im sure this is apple leaves. I looked up. Filled with the thirsty mouth the apples on the tree. So I made a poem: "apple is sweet and sweet, hard in it."

I love autumn, I love the autumn leaves.

我喜欢秋天的叶子。

走在山中，我又蹦又跳地在树林里跑着，这真是树叶的世界。梧桐树的叶子变黄了。梧桐树的叶子在空中翩翩起舞。飞啊飞啊，带走了夏天的炎热，带来了秋天的凉爽和清凉，还带来了丰收的季节。我爱秋天梧桐树的叶子。

我继续向前走着，一片树叶从我的眼前落下，于是，我好奇地把它接住。叶子只有巴掌那么大，叶脉很多，我看不出它是什么树的叶子，只好嗅了嗅。一股苹果清香冲进鼻子里，我敢肯定这是苹果的叶子。我抬头一看。树上结满了渴口的苹果。于是我造了一句诗来：“苹果甜又甜，辛苦在其中。”

我爱秋天，我更爱秋天的叶子。

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.

[经典英语作文：秋天叶子为什么会变颜色

秋天，叶子为什么会变颜色？

年年秋天，大自然这位老爷爷都会挥动神笔，把山山岭岭涂抹成了各种浅黄的、橘黄的或橘红的颜色。特别是一片片枫树，都披上了鲜红的衣裳，就好像一团团火焰，把整个山林都照亮了，十分耀眼。

秋天的树叶为什么要改变颜色呢？有一本书介绍说，早在公元前285年，希腊一位叫狄奥佛拉塔的哲学家就开始观察和研究秋叶变色的现象。可是，直到不久前，人们才知道这件事情的奥妙。

我们都知道，植物是通过叶片的光合作用获得所需的糖分和碳水化合物等养料的。光合作用离不开叶绿体，叶绿体中含有使叶片呈现绿色的叶绿素，同时还含有其他色素——不但有可使叶片变黄的叶黄素、类胡萝卜素，而且还有可使叶片变红的花青素。夏天，叶片中叶绿素的含量高，所以绿色占据了优势。随着气温的下降和白昼时间变短，叶绿素就会渐渐分解。这时候，叶片中的其他色素就显露出来了。叶绿素分解后，类胡萝卜素就使树叶变成浅黄、琥珀、金黄和橘黄等颜色。不同种类的树叶含有数量不同的类胡萝卜素，所以就形成了秋天山野五彩斑斓的景观。

植物界中，秋天里叶子会变颜色的，除了枫树之外还有许多种类——槭树、檫树、连香树、丝棉木、黄连木、爬山虎等。就连我们常见的一些蔬菜，比如胡萝卜、西红柿、辣椒等，也会随着季节的变化而改变颜色哩！

红叶是秋天的象征。“停车坐爱枫林晚，霜叶红于二月花”，置身在杜牧的诗句中，我产生了很多联想。红叶很平凡，也很谦虚。它从来不和百花争夺夏天，等到百花凋零的时候，它才站出来打造自己的天地。俗话说，“绿叶配红花”。可是，我好像听见它说：“我们叶子为什么就不能是红的呢？”于是，它迎着秋风展露风采，不鸣则已，一鸣惊人。你看，别的叶子都零落了，就好像是被它吓跑了。

我喜欢秋天的红叶，它用鲜艳的红色显示了生命的美丽。它告诉我们：秋天是最火热的季节，真正的生命不会枯萎！

Autumn, rice has matured in the paddy field, in a glance, seems to spread all over the floor of gold, and the farmer uncle one by one to pick up the "gold" in their field. The breeze blowing, golden ocean layers has moved.
