植物英语小短文

对不起,根据您的要求,我去找了,都是那么长的,还有比这更长的,我只能尽力而为了.1、Cells and Temperature Cells cannot remain alive outside certain limits of temperature and much narrower limits mark the boundaries of effective functioning. Enzyme systems of mammals and birds are most efficient only within a narrow range around 37C;a departure of a few degrees from this value seriously impairs their functioning. Even though cells can survive wider fluctuations the integrated actions of bodily systems are impaired. Other animals have a wider tolerance for changes of bodily temperature. For centuries it has been recognized that mammals and birds differ from other animals in the way they regulate body temperature. Ways of characterizing the difference have become more accurate and meaningful over time, but popular terminology still reflects the old division into "warm-blooded" and "cold-blooded" species; warm-blooded included mammals and birds whereas all other creatures were considered cold-blooded. As more species were studied, it became evident that this classification was inadequate. A fence lizard or a desert iguana-each cold-blooded----usually has a body temperature only a degree or two below that of humans and so is not cold. Therefore the next distinction was made between animals that maintain a constant body temperature, called home0therms, and those whose body temperature varies with their environments, called poikilotherms. But this classification also proved inadequate, because among mammals there are many that vary their body temperatures during hibernation. Furthermore, many invertebrates that live in the depths of the ocean never experience change in the depths of the ocean never experience change in the chill of the deep water, and their body temperatures remain constant. 2、American black bears American black bears appear in a variety of colors despite their name. In the eastern part of their range, most of these brown, red, or even yellow coats. To the north, the black bear is actually gray or white in color. Even in the same litter, both brown and black furred bears may be born. Black bears are the smallest of all American bears, ranging in length from five to six feet, weighing from three hundred to five hundred pounds Their eyes and ears are small and their eyesight and hearing are not as good as their sense of smell. Like all bears, the black bear is timid, clumsy, and rarely dangerous , but if attacked, most can climb trees and cover ground at great speeds. When angry or frightened, it is a formidable enemy. Black bears feed on leaves, herbs. Fruit, berries, insects, fish, and even larger animals. One of the most interesting characteristics of bears, including the black bear, is their winter sleep. Unlike squirrels, woodchucks, and many other woodland animals, bears do not actually hibernate. Although the bear does not during the winter moths, sustaining itself from body fat, its temperature remains almost normal, and it breathes regularly four or five times per minute. Most black bears live alone, except during mating season. They prefer to live in caves, hollow logs, or dense thickets. A little of one to four cubs is born in January or February after a gestation period of six to nine months, and they remain with their mother until they are fully grown or about one and a half years old. Black bears can live as long as thirty years in the wild , and even longer in game preserves set aside for them. 3、Sleep Sleet is part of a person's daily activity cycle. There are several different stages of sleep, and they too occur in cycles. If you are an average sleeper, your sleep cycle is as follows. When you fist drift off into slumber, your eyes will roll about a bit, you temperature will drop slightly, your muscles will relax, and your breathing well slow and become quite regular. Your brain waves slow and become quite regular. Your brain waves slow down a bit too, with the alpha rhythm of rather fast waves 1 sleep. For the next half hour or so, as you relax more and more, you will drift down through stage 2 and stage 3 sleep. The lower your stage of sleep. slower your brain waves will be. Then about 40to 69 minutes after you lose consciousness you will have reached the deepest sleep of all. Your brain will show the large slow waves that are known as the delta rhythm. This is stage 4 sleep. You do not remain at this deep fourth stage all night long, but instead about 80 minutes after you fall into slumber, your brain activity level will increase again slightly. The delta rhythm will disappear, to be replaced by the activity pattern of brain waves. Your eyes will begin to dart around under your closed eyelids as if you were looking at something occurring in front of you. This period of rapid eye movement lasts for some 8 to 15 minutes and is called REM sleep. It is during REM sleep period, your body will soon relax again, your breathing will slip gently back from stage 1 to stage 4 sleep----only to rise once again to the surface of near consciousness some 80 minutes later

“ABC” and "banana" A professor of mine once told a story about when she went to the United States to study.A native Eritrean, she had received a scholarship to pursue a bachelor's degree at an American university. The university organized a trip to Disneyland for her and the other international students. Before the group of international students went to Los Angeles, the coordinators of the trip informed the students from Africa that they should wear their "traditional" costumes, not Western-style clothing.Why?The coordinators were afraid that the African students would be "mistaken" for African-Americans simply because their skin color was also dark.At that time, the 1960s, there was still much overt racial discrimination against African-Americans.Insgroupsto avoid trouble, the coordinators wanted to make sure that their African students did not look African-American. ABC与香蕉 我上大学时的一位教授说起过她来美国上学时的一件事。作为一个厄立特里亚人，她得到了到美国上大学的奖学金。学校为她以及其他国际学生组织了一次去迪斯尼的出游活动。在这批国际学生去洛杉矶之前，活动组织者通知来自非洲的学生要穿上他们的传统彩衣，而不要穿西方人的衣服。这是为什么呢？组织者是担心非洲学生因其肤色是黑的而被误认为是美国黑人。在那时候——二十世纪六十年代，仍然存在着很多公然针对美国黑人的种族歧视。为了避免麻烦，组织者想确保自己的非洲学生看上去不像当地黑人。 She ended her story by asking us to think about what we thought she was before we had met her. Her last name is Italian; did we think she was Italian? When we first saw her, did we assume that she was a black American?How much can we really know about a person based upon hair color, skin color, facial structure or body shape? Identity is a difficult subject to discuss because it is so personal, and it is even more difficult to describe someone's identity clearly in a country like the USswheresjust about everyone's family came from somewhere else. My professor, until she left Eritrea, always considered herself Eritrean.When she got to America, however, people looked at her and saw a black woman, not an Eritrean woman. Similarly, Japanese, Koreans and Chinese people come to the US and are often just called "Asians".Appearance is used as the main condition for identity, although appearances can be quite deceiving. 她讲完了这段故事，要我们想一想在我们见到她之前是怎么猜想她的。她的姓是意大利人的姓，我们是不是以为她是意大利人？当我们第一次见到她时，是否以为她是个美国黑人？通过头发颜色、皮肤颜色、面部结构和体型，我们能真正了解一个人多少呢？ 一个人的身份是个难于讨论的题目，因为这是一个太个性化的问题。而在美国这样的国家，要想清楚地描述一个人的身份就更困难，因为这里几乎每一个人的家庭都来自另一个地方。我的这位教授在离开厄立特里亚之前，一直认为自己是厄立特里亚人。然而，在她到了美国之后，人们看到她后便见到了一个黑人妇女，并不知道她是厄立特里亚妇女。同样，日本人、韩国人和中国人到了美国后通常被叫做亚洲人。人的相貌是身份的主要方面，虽说相貌有时是很具有欺骗性的。 Is there a difference between a Chinese person born in China and a person born in the US to parents from China?Most people would agree that there is.There are certain phrases that people frequently use insgroupsto define the Chinese-American identity. The two most commonly heard terms are "ABC", meaning an American-born Chinese, and "banana".The former is often considered an acceptable label for people of Chinese descent born in the US; in Canada there is the corresponding term "CBC" for Canadian-born Chinese.The second term, banana, is usually regarded as derogatory or offensive, and it refers to someone who is "yellow" on the outside but "white" on the inside. The phrase ABC is used so commonly that many people think it is an appropriate description of Chinese-Americans.However, the phrase hides what I think is a very dangerous belief about identity. Identity is developed and learned, not given at birth.To say that someone is an American-born Chinese is to suggest that if that person were born anywhere else in the world, he/she would still be fundamentally Chinese because Chineseness, the quality of being Chinese, is inherent in this person.It implies that an ABC is Chinese first and just happened to be born in the United States.Yet being Chinese is not an inherent quality that one person has simply because he or she looks Chinese.Just about every Chinese-American recognizes that there are huge differences in personality, behavior and physical appearance between themselves and their native Chinese counterparts. 一个生在中国的中国人与一个父母来自中国但生在美国的人之间有什么不一样吗？多数人会同意有所区别。有一些人们常常使用的惯用语用来界定美国华人的身份，两个最常听到的是“ABC”和香蕉，前者是“出生在美国的中国人”的英文缩写，通常被认为是可以接受的用给出生在美国的中国人后裔贴的标签；在加拿大也有相应的说法“CBC”，用来指在加拿大出生的中国人。第二个惯用语香蕉，通常被认为是贬义的或是冒犯人的，它是指某人外表是黄皮肤而内心却是白人的一套。 ABC一词被用得如此之广泛，以至于很多人认为用它形容美籍华人挺合适。然而，这个词隐藏着我认为是对身份而言很危险的信条。身份是后天发展起来的，是不断学来的，并不是出生时就定下来的。说某人是出生在美国的中国人，也就暗示着这个人不管生在世界的什么地方，可从根上还是中国人，因为中国特性，也就是作为一个中国人所具有的品质是此人固有的。它暗含着一个ABC首先是中国人，只不过碰巧生在了美国。然而，一个中国人的品质，并非仅仅是因为他或她长得像中国人而固有的品质。几乎每一个美籍华人都意识到自己与土生土长的中国人在个性、举止、外表等方面有着很大差异。 These differences are what the term "banana" addresses.Bananas are yellow-skinned but with white insides - for people, this is meant to describe individuals who look Chinese but whose "insides", that is, their behavior and personality, are "white".But this also carries a demeaning and offensive undertone: that these people are only half-real, they are neither completely Chinese nor actually white. Even worse, the term is sometimes used to suggest that Chinese-Americans really wish that they were white.Being white, of course, is assumed to mean being American, which is a third misconception.Not all Americans are white, and in not too many years the majority of the population in America won't be white (i.e. of purely European descent) at all. Identity for everyone is a matter of experience and circumstance, not skin color or general appearance.What terms like ABC and banana ignore is that being Chinese-American constitutes a very real identity in its own right.Chinese-Americans are not necessarily caught between the East and the West.The Chinese-American identity is one that has developed over many generations in the US (since the 1840s), but one that can also be shared by recent immigrants and their families.It is important because it is different, because it is the product of blending social and cultural influences, and these differences should be recognized and not brushed aside. 这些差异正是“香蕉”一词所要说明的。香蕉外黄里白——对于人来说，这用来形容那些看上去是中国人但是“内里”也就是举止、个性都是“白人”式的。但它具有贬损和冒犯人的含义：这些人只是一半真实的人，他们既不是完全的中国人也不是真正的白人。更糟的是，这一叫法有时被用来暗指美籍华人实际上希望自己是白人。当然，一个白人会被认为是美国人，这是另一个错误概念。并非所有的美国人都是白人，用不了很多年，美国人口的多数就根本不会是白人(也就是纯欧洲人的后裔)了。 每个人的身份是经历与环境造就的，而不是皮肤的颜色或一般的长相所界定的。ABC与香蕉的叫法所忽略的是：一个美籍华人自身就包含着非常实在的身份。美籍华人并不一定在东西方的文化中左右为难。美籍华人的身份是那种自19世纪40年代起在美国繁衍了好几代的人，与那些最近移民到美国的人及其家庭是不一样的。身份之所以重要，是因为身份各不相同，也因为它是社会影响与文化影响相融的产物。这一区别应该被人们所认识，而不该受到忽视。

5、田野中的油菜花，大约有两尺多高了，那金黄色的油菜花又像是描绘在绿色新装上的装饰图案。在阳光的照耀下，一大片一大片的油菜花金光闪闪，格外耀眼。这时候，你如果走进田野，一阵阵清香会随风飘来，整个田野都浸在香海中了。“嗡嗡嗡……”小蜜蜂飞来了，采走了香的粉，酿出了甜的蜜。

植物睡眠在植物生理学中被称为睡眠运动，它不仅是一种有趣的自然现象，而且是个科学之谜。 每逢晴朗的夜晚，我们只要细心观察，就会发现一些植物已发生了奇妙的变化。比如常见的合欢树，它的叶子由许多小羽片组合而成，在白天舒展而又平坦，一到夜幕降临，那无数小羽片就成双成对地折合关闭，好像被手碰过的含羞草。 有时，我们在野外还可以看到一种开紫色小花、长着3片小叶的红三叶草，白天有阳光时，每个叶柄上的叶子都舒展在空中，但到了傍晚，3片小叶就闭合起来，垂着头准备睡觉。花生也是一种爱睡觉的植物，它的叶子从傍晚开始，便慢慢地向上关闭，表示要睡觉了。以上所举实例仅是一些常见的例子，事实上，会睡觉的植物还有很多很多，

Plants in plant physiology called sleep sleep movement, it is not only a natural phenomenon, a kind of fun and a scientific mystery. Every clear night, as long as careful observation, we will find some plants have wonderful changes have taken place. Such as common tree, its leaves made up by many small pinnae, stretch and even during the day, once in darkness, the many small pinnae into pairs or closed, as if by hand touch sensitive plant. Sometimes, we can also see a purple blossoms in the field, with 3 slices of lobular red clover, the sunshine during the day, when every leaf petioles stretch in the air, but by the end of the evening, the three close up lobule, hanging his head ready to go to sleep. Peanut plant of sleep is also a kind of love, it leaves start in the evening, then slowly shut up, said to go to bed.

Save the Wild Animals

Many wild animals are facing the danger of extinction, because the environment that they are living in has changed greatly. For example, with the developmet of cities, the using of insecticide and serious pollution, their living areas have become narrowcr and narrower. Many of the wild animals, now are confronted with food crisis. At the same time, man is killing off species just for getting their fur, skin, horns, teeth and meat.

In order to protect our resources of ecology, people should realize that the loss of any species is at least the loss of source of knowledge and a source of natural beauty. There fore, measures of the following should be taken: pollution standards are made to keepdown poisons; killing off certain rare species is prohibited; national parks should be set up as wild life, reserves.

Only if we human beings take some drastic measures can wild animals be preserved.

保护野生动物

许多野生动物正面临绝种的危险，因为它们生活的环境发生了极大的变化。譬 如，随着城市的发展，杀虫剂的使用和严重的污染，野生动物的生活区域变得越来越狭小。许多野生动物目前正面临着食物方面的危机。同时，为了获取野生动物的毛、皮、角、牙齿和肉，人类正在屠杀野生动物。

为了保护生态资源，人们应当意识到任何物种的缺失，至少意味着知识资源和自然美的缺失。因此，应采取以下措施：制订污染标准以降低有毒物质；严禁杀害某些稀有物种；应建立国家公园作为野生动植物保护区。
