Innate immunity (also called natural or native immunity ) provides the early line of defense against microbes. it consists of cellular and biochemical defense mechanisms that are in place even before infection and are poised to respond rapidly to infections .These mechanisms react to microbes and to the products of injured cells . and they respond in essentially the same way to repeated infections .The principal components of innate immunity are (1) physical and chemical barriers. such as epithelia and antimicrobial chemicals Produced at epithelial surfaces: (2) phagocytic cells (neutrophils, macrophages) , dendritic cells. and natural killer (NK) cells: (3) blood proteins, including members of the complement system and other mediators of inflammation; and (4) proteins called cytokines that regulate and coordinate many of the activities of the cells of innate immunity. The mechanisms of innate immunity are specific for structures that are common to groups of related microbes and may

not ,distinguish fine differences between microbes.

固有免疫（又叫自然免疫或者先天性免疫）为抵制微生物提供了早期的天然防线。它

有细胞和生化机制构成，他们甚至在感染之前就已经开始运转，随时准备迅速应对感染。这些机制对微生物和受损细胞的产生做出反应，也已基本相同的方式应对重复感染。固有免疫主要成分是1.物理和化学屏障，比如上皮组织和上皮表层产生的抗菌化学物。2.噬菌细胞（嗜中性粒细胞，巨噬细胞），树突状细胞和自然杀伤细胞。3.血

蛋白，包括补体系统的成分和其他的炎症介质。4.一种叫做细胞因子的蛋白质能够调

节和协调固有免疫的细胞活动。固有免疫机制是专门针对成组的相关联微生物共同拥

有的结构的，他们可能无法分辨为生物之间的细小差别。

In contrast to innate immunity. there are other immune responses that stimulated by exposure to infectious agents and increase in magnitude and defensive capabilities with each successive exposure to a particular microbe Because this form of immunity develops as a response to infection and adapts to the infection. it is called adaptive immunity. The defining characteristics of adaptive immunity are exquisite specificity for distinct molecules and an ability to "remember" and respond more vigorously to repeated exposures to the same microbe .The adaptive immune

system is able lo recognize and react to a large number of microbial and nonmicrobial substances. In addition. it has an extraordinary capacity to distinguish between different , even closely related, microbes and molecules, and for this reason it IS also called specific immunity. It is also sometimes called acquired immunity. to emphasize that potent protective responses are “acquired" by experience .The main components of adaptive immunity are cells called lymphocytes and their secreted products. such as antibodies. Foreign substances that induce specific immune responses or are recognized by Symphocytes or antibodies are called antigens.与固有免疫相比，因接触感染因子而被激活的其它的免疫反应会因为与某一种微生物的反

复接触而体积增大和防御能力增强。因为这种形式的免疫会随着对感染的反应而发展

和调整，因此叫做适应性反应。适应性免疫的明确特征是对不同的分子有敏锐的特异性，他有记忆的功能能够对相同微生物的重复感染做出更加激烈的应答。适应性免疫

系统能够识别，并对大量的微生物和非微生物产生应答。此外，他有一种卓越的能力，

能够区别不同的甚至是关系紧密的微生物和分子。正因为如此，它有被成为特异性免疫，有时候也叫后天免疫，是为了强调这种强大的保护应答是因为（不断）接触而获得的。适应性免疫的主要成分是淋巴细胞和他们的分泌物比如抗体。诱发特异性免疫或者被淋巴细胞或抗体识别的外来物质被称为抗原。

Mechanisms for defending the host against microbes are present in some form in all multicellular organisms . These mechanisms constitute innate immunity The more specialized defense mechanisms that constitute adaptive immunity are found in vertebrates only. Two functionally similar but molecularly distinct adaptive immune systems developed at different times in evolution. About 500 million years ago, jawless fish. such as lampreys and hagfish. developed a unique immune system containing diverse lymphocyte-like cells that may function like lymphocytes in more advanced species and even responded to immunization The antigen receptors on these cells were variable leucine-rich receptors that were capable of recognizing many antigens but were distinct from the antibodies and T cell receptors appeared later in evolution. Most of the components of the adaptive immune system, including lymphocytes with highly diverse antigen receptors, antibodies. specialized lymphoid tissues, evolved coordinately within a short time in jawed vertebrates (e. g. , sharks). about 360 million years ago. The immune system has become increasingly specialized with evolution .

保护诉诸抵制微生物的机制在所有的多细胞生物中以某种形式存在着。这些机制构成了固有免疫。构成适应性免疫的更加特异的防御机制只有在脊椎动物身上才有。在进化过程中两种功能相似但是分子相异的适应性免疫系统在不同时期得到了发展。大约5亿年前，八目鳗和盲鳗这些无颚鱼进化了一种独一无二的免疫系统，它有各种像淋巴细胞一样的细胞，能在更加高级的物种里像淋巴细胞一样发挥作用，甚至能对免疫应答。这些细胞上的抗原受体是多变的亮氨酸受体，能够识别许多的抗原，但是却和后来进化过程中出现的抗体和T细胞不同。适应性免疫系统的大多数成分，包括带有高度多样化抗原受体的淋巴细胞，抗体和特异的淋巴组织，是在3亿6千万年前在有颚脊椎动物（比如鲨鱼）中短时间里协调进化的。免疫系统也在进化过程中日益特异化。

Innate and adaptive immune responses are components of an integrated system of host defense in which numerous cells and molecules function cooperatively. The mechanisms of innate immunity provide effective initial defense against infections. However. many pathogenic microbes have evolved to resist innate immunity. their elimination requires the more powerful mechanisms of adaptive immunity .There are many connections between the Innate and adaptive immune systems. The innate immune response to microbes stimulates adaptive immune responses and influence nature of the adaptive responses Conversely. adaptive immune responses often work by enhancing the protective mechanisms of innate immunity, making capable of effectively combating pathogenic microbes.

固有免疫和适应性免疫是宿主整个防御系统组成成分，无数的细胞和分子彼此协作。固有免疫的机制对感染提供早期的有效防御，然而，一些病原微生物已经进化到可以抵制固有免疫，消除他们需要更加强大的适应性免疫机制。固有免疫和适应性免疫有

千丝万缕的联系，对微生物的固有免疫应答会激发适应性免疫应答，影响适应性免疫的性质。反过来，适应性免疫应答常常通过加强固有免疫的保护机制是自己有能力和病原微生物有效的战斗。

Unit 4 Fresh Start In-Class Reading Fresh Start 新的开端 1当我父母开车离去，留下我可怜巴巴地站在停车场上时，我开始寻思我在校园里该做什么。我决定我最想做的就是平安无事地回到宿舍。我感到似乎校园里的每个人都在看着我。我打定主意：竖起耳朵，闭上嘴巴，但愿别人不知道我是新生。 2第二天早上我找到了上第一堂课的教室，大步走了进去。然而，进了教室，我又碰到了一个难题。坐哪儿呢？犹豫再三，我挑了第一排边上的一个座位。3“欢迎你们来听生物101 课，”教授开始上课。天哪，我还以为这里是文学课呢！我的脖子后面直冒冷汗，摸出课程表核对了一下教室——我走对了教室，却走错了教学楼。 4怎么办？上课途中就站起来走出去？教授会不会生气？大家肯定会盯着我看。算了吧。我还是稳坐在座位上，尽量使自己看起来和生物专业的学生一样认真。 5下了课我觉得有点饿，便赶忙去自助食堂。我往托盘里放了些三明治就朝座位走去，就在这时，我无意中踩到了一大滩番茄酱。手中的托盘倾斜了，我失去了平衡。就在我屁股着地的刹那间，我看见自己整个人生在眼前一闪而过，然后终止在大学上课的第一天。 6摔倒后的几秒钟里，我想要是没有人看见我刚才的窘相该有多好啊。但是，食堂里所有的学生都站了起来，鼓掌欢呼，我知道他们不仅看见了刚才的情景，而且下决心要我永远都不会忘掉这一幕。 7接下来的三天里，我独自品尝羞辱，用以果腹的也只是些从宿舍外的售货机上买来的垃圾食品。到了第四天，我感到自己极需补充一些真正意义上的食物。也许三天时间已经足以让校园里的人把我忘在脑后了。于是我去了食堂。 8我好不容易排队取了食物，踮脚走到一张桌子前坐下。突然我听到一阵熟悉的“哗啦”跌倒声。抬头看见一个可怜的家伙遭遇了和我一样的命运。当人们开始像对待我那样鼓掌欢呼的时候，我对他满怀同情。他站起身，咧嘴大笑，双手紧握高举在头顶上，做出胜利的姿势。我料想他会像我一样溜出食堂，可他却转身重新盛一盘食物。就在那一刻，我意识到我把自己看得太重了。

3.Many products for sale seem to scream at us, "Buy me! Buy me!" Advertising is a big busin ess in our world with many products competing for our attention. Think of the last time you boug ht clothes. You probably noticed the variety of colors, patterns, fabrics and brands you could choo se from. Which kind of soft drink would you like to have today or what kind of computer do you want? Advertisers are skilled in the art of making their products look the best to appeal to our se nses. But products aren't always what they seem. Sometimes advertising is deceptive and as cons umers ,we must be careful about what we choose to buy. It is important to learn to compare prod ucts and identify our purpose in purchasing the things we need. But the good thing about advertising is that it helps people to make decisions and refine thei r choices. In the United States, the Ad Council creates timely public service messages to the nation. Th eir purpose is to raise awareness of public problems that citizens can respond to. Inspiring ads ca use individuals to take action and even save lives. Pollution in America, for example has been red uced over the years because of the creative Public Service advertisements that the council provid es" Please, please don't be a litter bug, 'cause every 'litter bit' hurts." Many families have taught t heir children to place litter in the trash can in response to this catchy phrase, which has affected g enerations as each succeeding generation has taught their children not to litter. 4.Nature imposes difficult conditions upon the earth from time to time . The tornado and fo rest fire destroy natural resources ,homes and other structures ,and very often harm or kill peopl e . Technological tragedies happen with little or no warning as we see trains crash and airplanes f all from the sky shortly after take-off. As tragic as calamities are , they seem to bring out the best in human nature . people trained in em ergency care arrive at the scene and begin assisting the inj ured .Others come with equipment to remove debris. Men , women ,and young people willingly c ome to the scene of an accident , hoping to be of help in some way . These selfless acts of kindne ss make our world a better place . compassion eases the wounds of calamities. American Airlines flight number 587 crashed less than three minutes after taking off from JF K Airport in New York in November,2001. Witnesses s aw an engine fire develop on the plane’s nu mber one engine located under the left wing of the aircraft .seconds later ,the airliner crashed int o eight homes ,completely destroying four of them .All 260 people aboard the airplane were kille d along with six people at the crash site ,leaving many people to mourn the loss of their loved on es .the residents (people who live in the area of the crash ) rallied together to comfort those griev ing, while others removed bodies from the wreckage and did the necessary clean-up. 工程实施困难的条件下在地上的时候。龙卷风和森林火灾破坏自然资源,房屋和其他建筑物,和经常伤害或杀死人。技术的悲剧发生在很少或没有预警,因为我们看到火车事故,飞机起飞后不久就从天空坠落。一样悲惨的灾难,他们似乎显示出人性中最好的。在急诊受训的人到达现场并开始帮助受伤的人则跟设备清除残骸。男人,女人,和年轻人自愿来到事故现场,希望能有帮助。这些无私的善举让我们的世界变得更美好。同情减轻灾害的伤口。 美国航空公司587号航班坠毁不到三分钟后从纽约肯尼迪机场起飞,11月2001。目击者看到一个引擎火灾发展在飞机上的1号引擎位于下飞机的左翼,接着后,客机坠毁八家,完全摧毁了四个260名乘客的飞机遇难连同6人在事故现场,造成许多人悼念失去的亲人,居民(住在崩溃的面积)聚集在一起,安慰那些悲伤,而另一些人则从残骸,并把尸体移走必要的清理。 5.Success can be reached in different ways by people in different careers. Bill Gates began at age to program computers,His vision for personal computing has been central to the success of M icrosoft Corporation, the company he founded with his childhood friend in 1975 . The former CEO of General Electric, Jack Welch, is a business legend. A famous quote by Mr. Welch is,” Chang before you have to. ”He believes in leading by example and encourages his empl oyees to do their best every day. Michael Jordan s aid,”I accept failure, but I can’t accept not trying.” He is one of the best athl etes to ever play team sports. His great smile, athletic achievements, and pleasant personality ha ve made him one of the most famous athletes in the world.

Unit 1 Personal Relationship In-Class Reading The Gift of Life 以生命相赠 1 炸弹落在了这个小村庄里。在可怕的越南战争期间，谁也不知道这些炸弹要轰炸什么目标，而它们却落在了一所由传教士办的小孤儿院内。 2 传教士和一两个孩子已经丧生，还有几个孩子受了伤，其中有一个小女孩，8岁左右，双腿被炸伤了。 3 几小时后，医疗救援小组到了。医疗小组由一名年轻的美国海军医生和一名同样年轻的海军护士组成。他们很快发现有个小女孩伤势严重。显然，如果不立即采取行动，她就会因失血过多和休克而死亡。 4 他们明白必须给小女孩输血，但是他们的医药用品很有限，没有血浆，因此需要匹配的血型。快速的血型测定显示两名美国人的血型都不合适。而几个没有受伤的孤儿却有匹配的血型。 5 医生会讲一点越南语，护士会讲一点法语，但只有中学的法语水平。孩子们不会说英语，只会说一点法语。医生和护士用少得可怜的一点共同语言，结合大量的手势，努力向这些受惊吓的孩子们解释说，除非他们能输一些血给自己的小伙伴，否则她将必死无疑。然后他们问孩子们是否有人愿意献血来救小女孩。 6 对医生和护士的请求，孩子们瞪大眼睛，一声不吭。此时小病人生命垂危。然而，只有这些受惊吓的孩子中有人自愿献血，他们才能够得到血。过了好一会儿，一只小手慢慢地举了起来，然后垂了下去，一会儿又举了起来。 7 “噢，谢谢，”护士用法语说。“你叫什么名字？” 8 “兴，”小男孩回答道。 9 兴很快被抱到一张床上，手臂用酒精消毒后，针就扎了进去。在整个过程中，兴僵直地躺着，没有出声。 10 过了一会儿，他发出了一声长长的抽泣，但立即用那只可以活动的手捂住了自己的脸。 11 “兴，疼吗？”医生问。 12 兴默默地摇了摇头，但一会儿忍不住又抽泣起来，并又一次试图掩饰自己的哭声。医生又问是不是插在手臂上的针弄疼了他，兴还是摇了摇头。 13 但现在，偶尔的抽泣变成了持续无声的哭泣。他紧紧地闭着眼睛，用拳头堵住嘴，想竭力忍住哭泣。 14 医疗小组此时非常担忧，因为针不会使他们的小输血者一直感到疼痛。一定是哪里出了问题。恰好这时，一名越南护士前来帮忙。看到小男孩在哭，她用越南话很快地问他原因。听了小男孩的回答后，又立即作了回答。护士一边说，一边俯身轻轻拍着小男孩的头，她的声音亲切柔和。 15 一会儿，小男孩不再哭了，他睁开眼睛，用质疑的目光看着越南护士。护士点了点头，小男孩的脸上马上露出了宽慰的神色。 16 越南护士抬起头平静地对两名美国人说: “他以为自己快死了。他误解了你们。以为你们要他献出所有的血，小女孩才能活下来。” 17 “那他为什么还愿意这么做呢?”海军护士问。 18 越南护士把这个问题向小男孩重复了一遍。小男孩简单地回答道: “她是我的朋友。” 19 他为了朋友甘愿献出自己的生命，没有比这更伟大的爱了。

unit1响尾蛇伤 我们在西波顿种植西瓜和香瓜供应市场。我家有一块瓜地和花圃在紧靠甘蔗地的谷仓背后。一天，我从工具棚里拿了把镰刀想去砍个西瓜自己吃。他们是不许我拿这把刀的，因为它的刀刃比我的胳膊还长。但它是切西瓜的最好工具。一刀下去，西瓜就一分为二了。 我正沿着瓜地边走边拍打着想找一个熟瓜，突然感觉脚好像被针一样的东西扎了一下。我为是踩在一堆蒺藜草上了。 转眼一看，却发现是一条响尾蛇。我知道响尾蛇在袭击之前都要发出响声以示警告的，而我对那响声的熟悉程度决不亚于我熟悉鹌鹑。后来我才明白它是没有时间警告，我肯定是一脚踩在它的嘴巴上了。我边往家飞奔，边大声喊叫，满脑子想的都是自己肯定要死了。妈妈赶快解下围裙用上面的带子绑在我的膝盖上部。她扶我到前屋的沙发上躺下，让玛莎照看我。当时在场的既没有一个男人也没有一匹马。最近的住宅是豪威尔先生家，但他家没有马。再远点的是吉姆·安德森家，穿过田地抄近路也有半英里的距离。妈妈冲向安德森家。安德森的一个儿子跳上马就直奔城里，在安德森家打工的克拉克的儿子用车把妈妈送回家。回到家，妈妈发现围裙带已被玛莎解开了，因为我直叫系得太紧。妈妈给我重新绑上，她用力很猛以致于我失声叫了起来。 然后，妈妈又到门廊朝那条通往城里的路张望。这条路位于安德森和豪威尔两家领地中间，一直延伸到小山顶端，因此从这里你可以看见所有路过的人或物。我总是远远就能辨认出我们的马车和汤姆，尤其是爸爸赶车的时候。这时，如果得到允许，汤姆就会因为急于吃到马槽里的东西而撒腿跑起来，爸爸也总是允许它这么做的。 赫伯·安德森的意见是首先找爸爸，如果他不在就找麦肯斯医生，再不成就找菲尔德或别的医生。 妈妈一边盯着看谁的马先出现，一边不时地进屋安慰我。 终于，妈妈说道：“你爸爸来了。” Read more 误解 这是个古老的故事，的确是要说到1864年的事。那时，英国军队驻扎在牙买加的一个团养了只官兵都喜爱的大猴子。那是只善于思考、极有主见的猴子，他的行为习惯和举止总是令军官们开心不已。他的居所对着军官食堂的窗户，尽管身上系着很长但不重的链子，他照样自得其乐，淘气逗人。比如有一天，他觉得一位年轻军官羞侮了他，便立即把食堂窗户敲得惊天动地。军官们只好把他的居所移到一个不太招眼的地方，但他依旧自娱自乐。任何活生生的东西，只要胆敢闯入他链长所及的范围内，就免不了被折腾得手忙脚乱一阵子。而那些倒霉的鸡鸭，却经常误入他的领地。那就会被他一下子抓住，有时竟被他扼杀，不过更多的时候，他都是恶作剧地对这些痛苦的阶下囚实施全身或半身拔毛手术，然后再放开。 然而，有一只鸡却让他突然强烈地喜欢上了。他是逮住了它，但他即不拔毛也不扼杀，反倒是百般怜惜、抚爱有加。这种毫无顾忌的举动使那只不幸的鸡恐怕是宁受拔毛之刑吧。猴子拧它，揉它，抚摸它，搂抱它，把它举得高高地，令它展翅起舞，又把它放开一会儿，可当它试图逃脱时又顽皮地将它两腿一抓。可那只鸡怎么地都不领情，反倒是完全误解了猴情猴意。但猴子却始终不渝，牢牢地紧握着这个心肝宝贝不放松。他满以为忠贞不渝的柔情蜜意即能赢得芳心归，没想到讨好卖乖了一番却不成功，因而更加大献殷勤：不一样地抚摸，更挚着地摩挲，更卖力地搓揉，还逗得它更欢快地舞蹈。可万分钟情也未能赢得回眸一顾。终于，在猴子极其亲昵的拥抱中，鸡给整死了，至死也未能理解猴的一片赤诚。 猴子处于极度悲伤之中。可想而知，他好不容易发现心爱之鸡，而这心爱之鸡未能回报丝毫之柔情，竟弃他而去！可悲复可怜！他开始着手祭奠的仪式，每一动作都表现出他沉痛
