A Poison Tree一棵有毒的树By William Blake作者：辛献云来源：《新东方英语·中学版》2013年第06期I was angry with my friend：I told my wrath1）， my wrath did end.I was angry with my foe2）：I told it not， my wrath did grow.And I watered it in fears，Night and morning with my tears；And I sunned it with smiles，And with soft deceitful wiles3）.And it grew both day and night，Till it bore an apple bright.And my foe beheld it shine.And he knew that it was mine，And into my garden stoleWhen the night had veiled4） the pole；In the morning glad I seeMy foe outstretched beneath the tree.我的朋友让我生气，我把怒气说出，怒气自然停息；我的仇敌让我愤怒，我压抑不说，愤怒长成一棵树。

我把泪珠当做雨露，日夜在恐惧中浇灌愤怒之树。

我把微笑当做阳光，还有温柔的欺骗花样。

它日日夜夜不停地生长，结出一颗苹果，光鲜漂亮。

我的仇敌看到它的鲜艳，他知道那是我的果园。

在一个星斗黯淡的夜晚，他偷偷溜进我的果园。

早上我欣喜地发现，我的仇敌直挺挺地躺在树边。

威廉·布莱克（William Blake， 1757～1827），英国18世纪重要的浪漫主义诗人，主要诗作有诗集《纯真之歌》（Songs of Innocence）、《经验之歌》（Songs of Experience）等。

Today I want to tell you all about my super awesome day with Koalas at the zoo. It was so cool!So, first things first, I woke up super early because I was so excited to see the Koalas. I had my breakfast and got ready in my best clothes. Mom and Dad took me to the zoo and as soon as we got there, I ran straight to the Koala exhibit.The Koalas were so cute and fluffy! They were just chilling on the trees, eating their eucalyptus leaves. I learned that Koalas sleep for like 18 hours a day, can you believe that? I wish I could sleep that much!I even got to pet a Koala! It was so soft and cuddly. I felt like I was in a dream. The zookeeper told us all about Koalas and how they are endangered, so we need to protect them.

My name is Lucy and I want to tell you about the coolest experience I had with a koala. It all happened last summer when my family and I went on a vacation to Australia. We visited a wildlife sanctuary and that's where I met the famous Australian animal - the koala.I was so excited when I saw the koala for the first time. It was hanging on a eucalyptus tree, munching on leaves. It looked so fluffy and cute! I couldn't resist and asked the caretaker if I could pet it. The caretaker told me that koalas are wild animals and it's not safe to touch them. So, I just stood there admiring it from a safe distance.But guess what? The koala must have sensed my excitement because it climbed down from the tree and walked right up to me! I couldn't believe it! It was so close, I could see its fluffy ears and big round eyes. It even sniffed my hand with its cute little nose.The caretaker told me that koalas are not as cuddly as they look and they can be a bit grumpy. But this koala seemed so friendly and curious. I felt so special to have this close encounter with such an amazing creature.I will never forget that day when I met the koala. It was a magical experience that I will cherish forever. Who knew a wild animal could be so cute and lovable? I hope to visit Australia again someday and see more koalas in the wild. Until then, I'll always remember my special moment with the koala.篇5Title: My Adventures with KoalasHello everyone! Today I'm going to tell you about my amazing adventures with koalas. I hope you enjoy reading all about it!It all started when my family and I went on a trip to Australia. We visited a wildlife sanctuary where we got to see lots of cool animals, but the koalas were my favorite. They were so cute and fluffy, and they loved to sleep in the trees all day long.I was lucky enough to get up close and personal with a koala named Charlie. He was hanging out in a eucalyptus tree, munching on some leaves. I got to pet him and feel how soft his fur was. It was like touching a fluffy cloud!After spending some time with Charlie, I learned that koalas are actually very lazy animals. They sleep for up to 20 hours a dayand only wake up to eat and move to a new tree. They also have sharp claws for climbing trees and strong jaws for munching on leaves.I also found out that koalas are very picky eaters. They only like to eat eucalyptus leaves, and they can be quite fussy about which ones they choose. I even got to help feed some leaves to the koalas, and they seemed to really enjoy them.Overall, my adventures with koalas were unforgettable. I learned so much about these amazing animals and had a great time getting to know them better. I can't wait to visit them again someday and maybe even help out with their conservation. Koalas are truly special creatures, and I'm so grateful to have had the chance to meet them. Thank you for reading my story!篇6Hello everyone! Today I'm going to tell you all about the sixth unit of our English textbook, which is all about koalas! Koalas are super cute and interesting animals, so let's learn more about them together.First of all, did you know that koalas are not actually bears? They are marsupials, which means they carry their babies in a special pouch on their bellies. How cool is that? They live inAustralia and eat eucalyptus leaves for their meals. But did you know that eucalyptus leaves are actually kind of poisonous to most animals? Koalas can eat them because they have a special digestive system that can break down the toxins.Koalas are known for being very sleepy animals. They can sleep for up to 18 hours a day! I wish I could sleep that much, don't you? They also have sharp claws for climbing trees and strong jaws for chewing those tough eucalyptus leaves. Koalas are really unique creatures, don't you think?In conclusion, koalas are amazing animals that we should all learn more about. They are cute, interesting, and important to the ecosystems they live in. I hope you enjoyed learning about koalas as much as I did. Thanks for listening and see you next time!。

unit2_main_textPart Two — Activity BOver the history of the earth, millions of animal and plant species have disappeared. Most of these species disappeared, or became extinct, because of natural causes such as climatic changes or a catastrophic event, like an asteroid hitting earth. What is different today is that most species that are in danger of becoming extinct are not endangered because of natural causes but because of human activity. T oday, we will be looking at the reasons that many plants and animals are endangered and how these reasons, or causes, are related to human activity.The single most important cause of endangered species today is the destruction and/or degradation of habitat. Most animals and plants are adapted to live and reproduce in a specific environment, or habitat. They cannot survive if they lose the specific habitat that they are adapted to live and reproduce in.There are many ways that human activity destroys habitat. For example, forests, grasslands, and deserts, which provide habitat to many plants and animals, arc cleared in order to develop residential areas for people to live in and industrial areas for people to work in. Land is also cleared to prepare it for farmers to grow crops on. Swamps and marshes, which provide habitat to many animal and plant species, are often drained and filled in, also to provide land for development or agriculture. In addition, rivers are sometimes dammed in order to provide people with electrical power. All of these human activities, such as clearing forests, grasslands, and deserts; draining swamps and marshes, and damming rivers result in the destruction of habitats that many plants and animals need to live and reproduce in.Closely related to the destruction of habitat is the degradation of habitat, which also endangers many species. Some examples of manmade causes that degrade habitat are oil spills, water pollution, and acid rain. You probably have seen pictures in newspapers or on TV of dead or dying marine animals and birds covered with oil after an oil tanker accident. Human beings also cause water pollution, which endangers the survival of many fish and marine animals. Acid rain, which results from people burning fossil fuels, also harms many species of fish and many species of trees. To sum up, some of the things related to human activity that result in the degradation of the environment are oil spills, water pollution, and acid rain.Illegal wildlife trade is the next major cause of endangered species. Although many governments have passed laws protecting endangered species, many animals are still illegally hunted. Sometimes people hunt these animals for food, but more often they hunt them only for specific parts of their bodies. For example, some species of animals such as tigers are illegally hunted for their furs. Elephants, which are the biggest land animals in the world and an endangered species, are often killed for their hides and tusks. These elephant hides and tusks are used to make souvenirs and works of art to sell to tourists and art collectors. Other animals such as chimpanzees are trapped to be sold to zoos for people to look at or for medical experiments. Some beautiful birds, such as some species of parrots, are in danger of extinction because so many are captured to be sold as pets to people all over the world.The third major cause that many species are endangered is over exploitation. People have always exploited, or used, plants and animals, and will no doubt, continue to do so. It is only whenpeople exploit animals and plants in an excessive manner that they become endangered. Some animals have already been hunted to extinction for food and sometimes for sport. Let me give you one well-known example-the passenger pigeon in the United States. Passenger pigeons were once so plentiful that people said they darkened the sky for hours, even days, when they flew over the land. Many people thought that the passenger pigeon could never disappear, but, in reality, they became extinct at the beginning of the 20th century. They became extinct as a result of over hunting, partly for food but mostly for sport. Today, some fish, like the cod, which /s an important source of food for people in many parts of the world, have been over fished. As a result, cod are in danger of becoming extinct. At one time cod, like passenger pigeons, were very plentiful, and it seemed they could never be gone. And it's not just animal species like the codfish that are in danger of becoming extinct.According to a recent article in the New Scientist, the Brazil nut tree, a very important source of nuts for both animals and people, is endangered due to over harvesting of the nuts.The fourth and final reason that some species today are endangered has to do with competition that is directly related to human activity. As you know, most animal and plant species have to compete with other species in their habitat for food, water, and any other resources they both need. This is usually natural, that is, not related to human activity. However, some animal and plant species today also face competition that is directly related to human activity. There are two kinds of competition that animal and plant species can face that is related to human activity. One has to do with domestic animals and the other has to do with what is call ed "introduced" species. Let’s discuss competitionwith domestic animals first.I'm sure you are all familiar with most domestic animals such as cattle, horses, sheep, goats, and so forth. But did you know that these domestic animals can be a threat to wild, that is, non-domestic, animals? The first reason is because for habitat with wild animals. And, these domestic animals often hunt, these domestic animals compete in addition, the people who own trap, and poison wild animals in order to protect their livestock. The wolf is an example of an animal that is widely hun.ted to near extinction to protect domestic animals.Another serious threat to some species is competition with introduced 8pecies, that is, plants or animals that are introduced, or brought, by humans into a new habitat, either on purpose or by accident. Take, for example, the introduction of a species of rabbit into Australia. In the 19th century, Europeanspurposely introduced a species of European rabbit into Australia so they could hunt them for sport. Unfortunately, this animal has caused great damage to the habitat of many native animals and plants of Australia. Another introduced species, the brown tree snake, was accidentally introduced into the island of Guam in the late 1940s. These snakes accidentally rode along on military cargo planes that landed there. Since that time, the brown tree snake has destroyed a large part of the bird population of Guam.Before I close, let me repeat the four major causes of endangered species today: (1) the destruction and/or degradation of habitat, (2) the illegal wildlife trade, (3) over exploitation, and (4) competition with domestic and “introduced” species.Let me conclude by saying that the relationship of all livingplants and animals is complex and interdependent. The destruction of one animal or plant species can threaten the survival of other species of animals and plants. Human beings are part of the natural world and they might also, one day, become an endangered species themselves. Because the four major causes of endangered species today are largely the result of human activity, only human beings can change the situation. Time is running out for many endangered plant and animal species.。

蚍蜉撼树英语作文单词Title: "The Flea's Challenge to the Tree"In the vast expanse of the forest, there stood a mighty oak tree, towering above all other flora, its branches reaching towards the heavens like outstretched arms. It was a symbol of strength and resilience, admired by all who beheld it. Yet, amidst the tranquil beauty of the forest, there existed a tale of unlikely defiance the tale of the flea's challenge to the tree.The flea, a tiny creature barely noticeable in the grandeur of nature, harbored within it a spirit of audacity unmatched by its diminutive size. With each leap, it dared to reach heights far beyond its reach, defying the limitations imposed upon it by its stature. And so it came to pass that one fateful day, the flea, emboldened by its own daring, dared to challenge the mighty oak tree.The tree, accustomed to the adulation of the forestinhabitants, regarded the flea's challenge with amusement and disdain. "What folly is this?" it murmured, its voice carried by the gentle breeze that rustled through its leaves. "Does this insignificant creature truly believe it can rival my strength?"Undeterred by the tree's skepticism, the flea persisted in its audacious endeavor. With each leap, it hurled itself against the trunk of the tree, its tiny frame trembling with determination. To the astonishment of all who witnessed it, the flea's relentless assault began to take its toll upon the tree.At first, the tree scoffed at the flea's efforts, dismissing them as nothing more than the futile antics of a foolish creature. But as the days passed and the flea continued its relentless assault, the tree could not help but feel a sense of unease gnawing at its core. Try as it might to ignore the tiny pest, the tree could not shake the feeling that the flea's challenge posed a threat to its very existence.As the struggle between the flea and the tree intensified, the forest itself seemed to hold its breath, waiting with bated breath to see the outcome of this unlikely contest. And then, in a moment that would be etched into the annals of forest lore for generations to come, the flea achieved the impossible it succeeded in toppling the mighty oak tree.In the aftermath of the tree's fall, a hush descended upon the forest, broken only by the triumphant chirping of the victorious flea. And though the tree lay defeated, its branches scattered upon the forest floor, it had learned a valuable lesson that true strength lies not in size or stature, but in the indomitable spirit of those who dare to defy the odds.In the years that followed, the tale of the flea's challenge to the tree became a source of inspiration forall who heard it, a reminder that even the meekest of creatures are capable of achieving greatness if only they dare to believe in themselves. And as for the flea, it continued to leap and bound through the forest, its spiritunbroken, forevermore a symbol of courage and determination in the face of adversity.The end.。
