JOHN SNOW DEFEATS “KING CHOLERA”
约翰·斯诺击败“霍乱王”
John Snow was a famous doctor in London - so expert, indeed, that he attended Queen Victoria as her personal physician.约翰·斯诺是伦敦一位著名的医生——他的确医术精湛,因而成为照料维多利亚女王的私人医生。But he became inspired when he thought about helping ordinary people exposed to cholera.但他一想到要帮助那些得了霍乱的普通百姓时,他就感到很振奋。This was the deadly disease of its day.霍乱在当时是最致命的疾病,Neither its cause nor its cure was understood.人们既不知道它的病源,也不了解它的治疗方法。So many thousands of terrified people died every time there was an outbreak.每次霍乱暴发时,就有大批惊恐的老百姓死去。John Snow wanted to face the challenge and solve this problem.约翰·斯诺想面对这个挑战,解决这个问题。He knew that cholera would never be controlled until its cause was found.他知道,在找到病源之前,霍乱疫情是无法控制的。
He became interested in two theories that possibly explained how cholera killed people.斯诺对霍乱致人死地的两种推测都很感兴趣。The first suggested that cholera multiplied in the air. A cloud of dangerous gas floated around until it found its victims.一种看法是霍乱病毒在空气中繁殖着,像一股危险的气体到处漂浮,直到找到病毒的受害者为止。The second suggested that people absorbed this disease into their bodies with their meals.第二种看法是人们在吃饭的时候把这种病毒引入体内的。From the stomach the disease quickly attacked the body and soon the affected person died.病从胃里发作而迅速殃及全身,患者就会很快地死去。
John Snow suspected that the second theory was correct but he needed evidence.斯诺推测第二种说法是正确的,但他需要证据。So when another outbreak hit London in 1854, he was ready to begin his enquiry.因此,在1854年伦敦再次暴发霍乱的时候,约翰·斯诺着手准备对此进行调研。As the disease spread quickly through poor neighbourhoods, he began to gather information.当霍乱在贫民区迅速蔓延的时候,约翰·斯诺就开始收集资料。In two particular streets, the cholera outbreak was so severe that more than 500 people died in ten days.他发现特别在两条街道上霍乱流行的很严重,在10天之内就死去了500多人。He was determined to find out why.他决心要查明其原因。
First he marked on a map the exact places where all the dead people had lived.首先,他在一张地图上标明了所有死者住过的地方。This gave him a valuable clue about the cause of the disease.这提供了一条说明霍乱起因的很有价值的线索。Many of the deaths were near the water pump
in Broad Street (especially numbers 16, 37, 38 and 40).许多死者是住在宽街的水泵附*(特别是这条街上16、37、38、40号)。He also noticed that some houses (such as 20 and 21 Broad Street and 8 and 9 Cambridge Street) had had no deaths.他发现有些住宅(如宽街上20号和21号以及剑桥街上的8号和9号)却无人死亡。He had not foreseen this, so he made further investigations.他以前没预料到这种情况,所以他决定深入调查。He discovered that these people worked in the pub at 7 Cambridge Street.他发现,这些人都在剑桥街7号的酒馆里打工,They had been given free beer and so had not drunk the water from the pump.而酒馆为他们免费提供啤酒喝,因此他们没有喝从宽街水泵抽上来的水。It seemed that the water was to blame.看来水是罪魁祸首。 Next, John Snow looked into the source of the water for these two streets.接下来,约翰·斯诺调查了这两条街的水源情况。He found that it came from the river polluted by the dirty water from London.他发现,水是从河里来的,而河水被伦敦排出的`脏水污染了。He immediately told the astonished people in Broad Street to remove the handle from the pump so that it could not be used.他马上叫宽街上惊慌失措的老百姓拆掉水泵的把手。这样,水泵就用不成了。Soon afterwards the disease slowed down.不久,疫情就开始得到缓解。He had shown that cholera was spread by germs and not in a cloud of gas.他证明了霍乱是由病菌而不是由气体传播的。
In another part of London, he found supporting evidence from two other deaths that were linked to the Broad Street outbreak.在伦敦的另一个地区,他从两个与宽街暴发的霍乱有关联的死亡病例中发现了有力的证据。A woman, who had moved away from Broad Street, liked the water from the pump so much that she had it delivered to her house every day.有一位妇女是从宽街搬过来的,她特别喜欢那里的水,每天都要派人从水泵打水运到家里来。Both she and her daughter died of cholera after drinking the water.她和她的女儿喝了这种水,都得了霍乱而死去。With this extra evidence John Snow was able to announce with certainty that polluted water carried the virus.有了这个特别的证据,约翰·斯诺就能够肯定地宣布,这种被污染了的水携带着病菌。
To prevent this from happening again, John Snow suggested that the source of all the water supplies be examined.为了防止这种情况的再度发生,约翰·斯诺建议所有水源都要经过检测。The water companies were instructed not to expose people to polluted water any more.自来水公司也接到指令,不能再让人们接触被污染的水了。Finally "King Cholera" was defeated.最终,“霍乱王”被击败了。
Unit 2 PUZZLES IN GEOGRAPHY 地理之谜
People may wonder why different words are used to describe these four countries: England, Wales, Scotland and Northern Ireland.人们也许觉得奇怪,为什么用来描述英格兰、威尔士、苏格兰和北爱尔兰这四个国家的词语不太一样。You can clarify this question if you study British history.但如果你学过英国历史,就能弄清楚这个问题。
First there was England. Wales was linked to it in the thirteenth century.首先是英格兰。威尔士于13世纪同英格兰联合了起来。Now when people refer to England you find Wales included as well.如今只要有人提起英格兰,你就会发现威尔士总是包括在内的。Next England and Wales were joined to Scotland in the seventeenth century and the name was changed to "Great Britain".接着,英格兰、威尔士同苏格兰于17世纪联合了起来,名字就改成了“大不列颠”。Happily this was accomplished without conflict when King James of Scotland became King of England and Wales
as well.令人庆幸的是,当苏格兰的詹姆斯国王成为英格兰和威尔士的国王时,这三个国家和*地实现了联合。Finally the English government tried in the early twentieth century to form the United Kingdom by getting Ireland connected in the same peaceful way.最后,英国*打算于20世纪初把爱尔兰也同另外三个国家和*联合起来以形成联合王国。However, the southern part of Ireland was unwilling and broke away to form its own government.然而,爱尔兰的南部却不愿意而分离出去了,并建立了自己的*。So only Northern Ireland joined with England, Wales and Scotland to become the United Kingdom and this was shown to the world in a new flag called the Union Jack.因此只有北爱尔兰同英格兰、威尔士、苏格兰联合起来,而组成了联合王国,这一点从新的联合王国**上就可以看得出来。
To their credit the four countries do work together in some areas (eg, the currency and international relations), but they still have very different institutions.值得赞扬的是,虽然这四个国家的确在一些方面共同合作,例如在货币和国际关系方面;但是它们在制度上仍然存在很大的区别。For example, Northern Ireland, England and Scotland have different educational and legal systems as well as different football teams for competitions like the World Cup!例如,北爱尔兰、英格兰和苏格兰在教育体制和立法体制上都存在着差异。在参加像世界杯之类的比赛时,它们有着各自的足球队。
England is the largest of the four countries, and for convenience it is divided roughly into three zones.在这四个国家中,英格兰是最大的。为了方便起见,它大致可以划分为三个地区。The zone nearest France is called the South of England, the middle zone is called the Midlands and the one nearest to Scotland is known as the North.最靠*法国的那个地区叫做英格兰南部,中部地区叫做英格兰中部,最靠*苏格兰的那个地区叫做英格兰北部。You find most of the population settled in the south, but most of the industrial cities in the Midlands and the North of England.你可以看到英国的大部分人口聚居在南部,而多数大工业城市都位于中部和北部。Although, nationwide, these cities are not as large as those in China, they have world-famous football teams and some of them even have two!尽管,英国任何一个城市都不像*的城市那样大,但是他们都有着自己的享有威名的足球队,有的城市甚至还有两个队。It is a pity that the industrial cities built in the nineteenth century do not attract visitors.很遗憾,这些建于19世纪的工业城市对游客并没有吸引力。For historical architecture you have to go to older but smaller towns built by the Romans.要找历史性建筑你得去更古老的、比较小些的由古罗马人建造的城镇。There you will find out more about British history and culture.在那儿你才可能找到更多的有

THEME PARKS — FUN AND MORE THAN FUN
Which theme park would you like to visit? There are various kinds of theme parks, with a different park for almost everything: food, culture, science, cartoons, movies or history.
Some parks are famous for having the biggest or longest roller coasters, others for showing the famous sights and sounds of a culture. Whichever and whatever you like, there is a theme park for you!
The theme park you are probably most familiar with is Disneyland.
It can be found in several parts of the world. It will bring you into a magical world and make your dreams come true, whether traveling through space, visiting a pirate ship or meeting your favourite fairy tale or Disney cartoon character.
As you wander around the fantasy amusement park, you may see Snow White or Mickey Mouse in a parade or on the street.
Of course Disneyland also has many exciting rides, from giant swinging ships to terrifying free-fall drops. With all these attractions, no wonder tourism is increasing wherever there is a Disneyland. If you want to have fun and more than fun, come to Disneyland!
Dollywood, in the beautiful Smoky Mountains in the southeastern
USA, is one of the most unique theme parks in the world. Dollywood shows and celebrates America's traditional southeastern culture. Although Dollywood has rides, the park's main attraction is its culture. Famous country music groups perform there all year in indoor and outdoor theatres.
People come from all over America to see carpenters and other craftsmen make wood, glass and iron objects in the old-fashioned way. Visit the candy shop to try the same kind of candy that American southerners made 150 years ago, or take a ride on the only steam- engine train still working in the southeast USA. You can even see beautiful bald eagles in the world's largest bald eagle preserve.
And for those who like rides, Dollywood has one of the best old wooden roller coasters, Thunderhead. It is world-famous for having the most length in the smallest space. Come to Dollywood to have fun learning all about America's historical southeastern culture!
If you want to experience the ancient days and great deeds of English knights and ladies, princes and queens, then England's Camelot Park is the place for you. Every area of the park is modelled after life in the days of King Arthur and the Knights of the Round Table. In one place, you can watch magic shows with Merlin the Wizard. If you want to see fighting with swords or on horseback, then the jousting area is a good place to visit.
If you do well there, King Arthur may choose you to fight in the big jousting tournament. Do you like animals? Then visit the farm area, and learn how people in ancient England ran their farms and took care of their animals. To enter a world of fantasy about ancient England, come to Camelot Park!
主题公园——是娱乐,又不仅仅是娱乐
你想要参观哪一个主题公园呢?(世界上)有各种各样的主题公园,不同的 公园有不同的主题,但几乎囊括了一切:
食物、文化、科学、卡通、电影及历史。 有一些主题公园因为有最大或者最长的过山车而闻名, 有些则展示了文化中那些 著名的声音和视觉景象。不论你喜欢哪一个,不管你喜欢什么,都会有一个适合 你的主题公园!
你最熟悉的主题公园很可能就是迪斯尼乐园吧。世界上好几个地方都有迪斯 尼乐园。无论你是在太空遨游,参观海盗船,还是邂逅你最喜欢的童话故事或者 迪斯尼卡通里的人物, 迪斯尼会把你带入一个魔幻的世界, 使你的梦想变成现实。
当你在游乐园漫步时,你可能会在*队伍中或者街上看到白雪公主或米老鼠。 当然,迪斯尼还有很多颇具刺激性的游乐设施,比如巨大的吊船和可怕的自由落 体(设施)。有所有这么多引人入胜的东西,难怪哪里有迪斯尼乐园,哪里的旅 游业就会兴旺。如果你想尽情娱乐,而且有更多的收获,那就来迪斯尼乐园吧!
位于美国东南部美丽的斯莫基山脉中的多莱坞,是世界上最独特的主题公园 之一。
多莱坞展示并欢庆美国东南地区的传统文化。尽管这里也有供搭乘的游乐 设施,但是公园最具吸引力的还是它的文化。著名的`乡村音乐乐团全年都会在露 天或室内的剧院演出。美国各地的人们来到这里,是为了观看木匠或其他工匠们 用老式的方法制作木制品、玻璃制品和铁制品。
还可以到糖果店品尝一下糖果, 这些糖果和 150 年前美国南方人制作的一模一样。或者乘一乘蒸汽火车,这可是 在美国东南部依然运转的唯一一辆蒸汽火车。

A PIONEER FOR ALL PEOPLE
Although he is one of China's most famous scientists, Yuan Longping considers himself a farmer, for he works the land to do his research. Indeed, his sunburnt face and arms and his slim, strong body are just like those of millions of Chinese farmers, for whom he has struggled for the past five decades. Dr Yuan Longping grows what is called super hybrid rice. In 1974, he became the first agricultural pioneer in the world to grow rice that has a high output. This special strain of rice makes it possible to produce one-third more of the crop in the same fields. Now more than 60% of the rice produced in China each year is from this hybrid strain.
Born into a poor farmer's family in 1930, Dr Yuan graduated from Southwest Agricultural College in 1953. Since then, finding ways to grow more rice has been his life goal. As a young man, he saw the great need for increasing the rice output. At that time, hunger was a disturbing problem in many parts of the countryside. Dr Yuan searched for a way to increase rice harvests without expanding the area of the fields. In 1950, Chinese farmers could produce only fifty million tons of rice. In a recent harvest, however, nearly two hundred million tons of rice was produced. These increased harvests mean that 22% of the world's people are fed from just 7% of the farmland in China. Dr Yuan is now circulating his knowledge in India, Vietnam and many other less developed countries to increase their rice harvests. Thanks to his research, the UN has more tools in the battle to rid the world of hunger. Using his hybrid rice, farmers are producing harvests twice as large as before.
Dr Yuan is quite satisfied with his life. However, he doesn't care about being famous. He feels it gives him less freedom to do his research. He would much rather keep time for his hobbles. He enjoys listening to violin music, playing mah-jong, swimming and reading. Spending money on himself or leading a comfortable life also means very little to him. Indeed, he believes that a person with too much money has more rather than fewer troubles. He therefore gives millions of yuan to equip others for their research in agriculture.
Just dreaming for things, however, costs nothing. Long ago Dr yuan had a dream about rice plants as tall as sorghum. Each ear of rice was as big as an ear of corn and each grain of rice was as huge as a peanut. Dr Yuan awoke from his dream with the hope of producing a kind of rice that could feed more people. Now, many years later, Dr Yuan has another dream: to export his rice so that it can be grown around the globe. One dream is not always enough, especially for a person who loves and cares for his people.
造福全人类的先驱者
尽管是*最著名的科学家之一,袁隆*仍然认为自己是个农民,因为他在田里耕作,进行科学研究。的确,他被太阳晒得黝黑的脸庞和和手臂,以及他那瘦削而又结实的身躯,就跟其他千百万*农民一样,过去50年来,他一直在努力帮助他们。袁博士种植的是被称为“超级杂交水稻的”的稻种。1974年,他成为世界上第一位种植高产水稻的农业先锋。这种特殊的稻种使得同样的田地多收获三分之一的产量。如今*每年出产的稻米有60%以上出自这种杂交稻种。
袁博士1930年出生,1953年毕业于西南农学院。从那时起,找到水稻高产的方法就成为他一生的目标。年轻时,他就看到了稻田增产的巨大需求。当时,饥荒是许多农村地区面临的严重问题。袁博士要在不增加土地面积的基础上寻求达到增收稻谷的途径。1950年,*农民只能生产五千万吨稻谷,而*来却生产了将*两亿吨稻谷。这一粮食产量的增加意味着*仅仅7%的耕地养活了世界22%的人口。袁博士现在在印度、越南和很多其他欠发达国家传播提高水稻产量的知识。多亏了他的研究,联合国在消除世界饥饿的战斗中有了更多的办法。用他的杂交水稻种子,农民种出的粮食比以前多了一倍。
袁博士很满意他的生活。但是,他对成名并不在意,并且觉得出名后搞科研就不那么自由了。他宁愿把时间花在自己的业余爱好上。他喜欢听小提琴乐曲、打麻将、游泳和读书。在自己身上花钱或者享受舒适的生活对袁博士来说意义不大。事实上,他认为一个人有了太多钱,他的麻烦事只会更多,而不是更少。于是,他拿出好几百万元帮助其他人进行农业科学研究。
梦想是不花本钱的。很久以前,袁博士曾在梦里看到水稻长得像高粱一样高,稻穗跟玉米穗一样大,而每粒稻谷像花生米一样大。袁博士从梦中醒来,希望能种植一种能养活更多人的水稻。在很多年后的今天,袁博士还有另外一个梦想,那就是他的稻谷可以出口并长遍全球。一个梦想总是不够的,尤其对一个热爱和关心人民的人来说更是如此。

高一物理必修二的学*,需要同学们总结高一物理必修二所学的知识点,这样才能全面地学好高一物理。为帮助大家节省总结的时间,小编为你进行总结。下面小编为大家提供高一物理必修二知识点总结,供大家参考。
曲线运动
1.在曲线运动中,质点在某一时刻(某一位置)的速度方向是在曲线上这一点的切线方向。
2.物体做直线或曲线运动的条件:
(已知当物体受到合外力F作用下,在F方向上便产生加速度a)
(1)若F(或a)的方向与物体速度v的方向相同,则物体做直线运动;
(2)若F(或a)的方向与物体速度v的方向不同,则物体做曲线运动。
3.物体做曲线运动时合外力的方向总是指向轨迹的凹的一边。
4.*抛运动:将物体用一定的初速度沿水*方向抛出,不计空气阻力,物体只在重力作用下所做的运动。
分运动:
(1)在水*方向上由于不受力,将做匀速直线运动;
(2)在竖直方向上物体的初速度为零,且只受到重力作用,物体做自由落体运动。
5.以抛点为坐标原点,水*方向为x轴(正方向和初速度的方向相同),竖直方向为y轴,正方向向下.
6.①水*分速度: ②竖直分速度: ③t秒末的合速度
④任意时刻的运动方向可用该点速度方向与x轴的正方向的夹角 表示
7.匀速圆周运动:质点沿圆周运动,在相等的时间里通过的圆弧长度相同。
8.描述匀速圆周运动快慢的物理量
(1)线速度v:质点通过的弧长和通过该弧长所用时间的比值,即v=s/t,单位m/s;属于瞬时速度,既有大小,也有方向。方向为在圆周各点的切线方向上
9.匀速圆周运动是一种非匀速曲线运动,因而线速度的方向在时刻改变
(2)角速度 :ω=φ/t(φ指转过的角度,转一圈φ为 ),单位 rad/s或1/s;对某一确定的匀速圆周运动而言,角速度是恒定的
(3)周期T,频率:f=1/T
(4)线速度、角速度及周期之间的关系:
10.向心力: 向心力就是做匀速圆周运动的物体受到一个指向圆心的合力,向心力只改变运动物体的速度方向,不改变速度大小。
11.向心加速度: 描述线速度变化快慢,方向与向心力的方向相同,
12.注意:
(1)由于 方向时刻在变,所以匀速圆周运动是瞬时加速度的方向不断改变的变加速运动。
(2)做匀速圆周运动的物体,向心力方向总指向圆心,是一个变力。
(3)做匀速圆周运动的物体受到的合外力就是向心力。
13.离心运动:做匀速圆周运动的物体,在所受的合力突然消失或者不足以提供圆周运动所需的向心力的'情况下,就做逐渐远离圆心的运动
万有引力定律及其应用
1.万有引力定律: 引力常量G=6.67× Nm2/kg2
2.适用条件:可作质点的两个物体间的相互作用;若是两个均匀的球体,r应是两球心间距.(物体的尺寸比两物体的距离r小得多时,可以看成质点)
3.万有引力定律的应用:(中心天体质量M, 天体半径R, 天体表面重力加速度g )
(1)万有引力=向心力 (一个天体绕另一个天体作圆周运动时 )
(2)重力=万有引力
地面物体的重力加速度:mg = G g = G ≈9.8m/s2
高空物体的重力加速度:mg = G g = G<9.8m/s2
4.第一宇宙速度----在地球表面附*(轨道半径可视为地球半径)绕地球作圆周运动的卫星的线速度,在所有圆周运动的卫星中线速度是最大的。
由mg=mv2/R或由 = =7.9km/s
5.开普勒三大定律
6.利用万有引力定律计算天体质量
7.通过万有引力定律和向心力公式计算环绕速度
8.大于环绕速度的两个特殊发射速度:第二宇宙速度、第三宇宙速度(含义)
功、功率、机械能和能源
1.做功两要素:力和物体在力的方向上发生位移
2.功: 功是标量,只有大小,没有方向,但有正功和负功之分,单位为焦耳(J)
3.物体做正功负功问题 (将α理解为F与V所成的角,更为简单)
(1)当α=90度时,W=0.这表示力F的方向跟位移的方向垂直时,力F不做功,
如小球在水*桌面上滚动,桌面对球的支持力不做功。
(2)当α<90度时,>0,W>0.这表示力F对物体做正功。

在我们的学*时代,看到知识点,都是先收藏再说吧!知识点是知识中的最小单位,最具体的内容,有时候也叫“考点”。那么,都有哪些知识点呢?下面是小编帮大家整理的高一数学必修二知识点,仅供参考,大家一起来看看吧。
一、直线与方程
(1)直线的倾斜角
定义:x轴正向与直线向上方向之间所成的角叫直线的倾斜角,特别地,当直线与x轴*行或重合时,我们规定它的倾斜角为0度.因此,倾斜角的取值范围是0°≤α<180°
(2)直线的斜率
①定义:倾斜角不是90°的直线,它的倾斜角的正切叫做这条直线的斜率.直线的斜率常用k表示.即.斜率反映直线与轴的倾斜程度.
当时,; 当时,; 当时,不存在
②过两点的直线的斜率公式:
注意下面四点:
(1)当时,公式右边无意义,直线的斜率不存在,倾斜角为90°;
(2)k与P1、P2的顺序无关;(3)以后求斜率可不通过倾斜角而由直线上两点的坐标直接求得;
(4)求直线的倾斜角可由直线上两点的坐标先求斜率得到。
(3)直线方程
①点斜式:直线斜率k,且过点
注意:当直线的斜率为0°时,k=0,直线的方程是y=y1
当直线的斜率为90°时,直线的斜率不存在,它的方程不能用点斜式表示,但因l上每一点的横坐标都等于x1,所以它的方程是x=x1.
②斜截式:,直线斜率为k,直线在y轴上的截距为b
③两点式:()直线两点,
④截矩式:
其中直线与轴交于点,与轴交于点,即与轴、轴的截距分别为
⑤一般式:(A,B不全为0)
注意:各式的适用范围 特殊的方程如:
*行于x轴的直线:(b为常数); *行于y轴的直线:(a为常数);
(5)直线系方程:即具有某一共同性质的直线
(一)*行直线系
*行于已知直线(是不全为0的常数)的直线系:(C为常数)

2022年必修一生物必备知识点
高中生学*必修一的生物时,不仅要明确要学*的知识,还要有勤奋的学*态度,勤复*学过的知识。下面是百分网小编为大家整理的2022年必修一生物必备知识点,希望对大家有用!
一、物质跨膜运输的方式:
(一)被动运输:
1、自由扩散:不需要载体和能量,如水、CO2、O2、甘油、乙醇等。
2、协助扩散:需要载体,但不需要能量,如红细胞吸收葡萄糖。
(二)主动运输:既需要载体协助,又需要消耗能量,如细胞吸收K、Na、Ca2、氨基酸等。
(三)物质跨膜运输的方式说明生物膜结构特征是流动性,功能特性是选择透过性。
(四)大分子物质以胞吞和胞吐方式进出细胞,这与细胞膜的流动性有关,但不属于跨膜运输。
二、三种物质出入细胞方式的图例比较
自由扩散 协助扩散 主动运输
三、主动运输的意义:
在细胞的生命活动过程中,主动运输起到了重要作用,它使细胞能主动地从外界吸收被选择的物质,供生命活动利用。同样,细胞也能利用主动运输把新陈代谢产物排出细胞外。总之,细胞通过主动运输,摄取、积累物质以及不断排出代谢废物,从而维持细胞组成成分的动态稳定,保证生命活动的正常进行。
四、影响跨膜运输的因素
(一)影响自由扩散的因素:细胞膜内外物质的浓度差。
(二)影响协助扩散的因素:
1、细胞膜内外物质的浓度差。
2、细胞膜上运载物质的载体数量。
(三)影响主动运输的因素:
1、载体:是细胞膜上的一类蛋白质。
(1)载体具有特异性,不同物质的载体不同,不同生物细胞膜上载体的种类和数目也不同。
(2)载体具有饱和现象,当细胞膜上的载体全部参与物质的运输时,细胞吸收该载体运载的物质的速度不再随物质浓度的增大而增大。
必修一生物知识总结
影响物质运输速度的曲线分析
1、物质浓度(在一定浓度范围内)对运输速率的影响曲线:
(1)自由扩散的运输方向是由高浓度一侧到低浓度一侧,其动力是两侧溶液的浓度差,在一定浓度范围内,随物质浓度的增大,其运输速率与物质浓度成正比。
(2)协助扩散或主动运输的共同点是都需要载体协助,在物质浓度较低时,随物质浓度的增大,运输速率也逐渐增大,到达一定物质浓度时,由于受膜上载体数量的限制,运输速率不再随浓度增大而增大。
2、氧气浓度对物质运输速率的影响曲线:
(1)自由扩散和协助扩散统称为被动运输,其运输方向都是从高浓度一侧到低浓度一侧,其运输的动力都是浓度差,不需要能量,因此与氧气浓度无关,运输速率不随氧气浓度增大而改变。
(2)主动运输方式既需要载体协助又需要消耗能量。在氧气浓度为零时,通过细胞无氧呼吸供能,但无氧呼吸产生能量较少所以运输速率较低,在一定范围内随氧气浓度升高,有氧呼吸加强,产生的能量逐渐增多,所以运输速率不断加快,当氧气浓度足够高时,能量供应充足,但由于受到载体数量的限制,运输速率不再随氧气浓度增大而加快。
必修一生物常考知识点
1、细胞是生物体结构和功能的基本单位。除病毒外,所有生物都是由细胞组成的。
2、生命系统的结构层次:细胞 →组织 →器官 →系统(植物没有) →个体 →种群 →群落 →生态系统 →生物圈
3、使用显微镜注意:
(1)放大倍数(长度)=物镜的放大倍数×目镜的放大倍数
(2)物镜越长,放大倍数越大 目镜越短,放大倍数越大 “物镜—玻片标本”越短,放大倍数越大
(3)物像与实际材料上下、左右都是颠倒的
(4)高倍物镜使用顺序:低倍镜→标本移至中央→高倍镜→大光圈,凹面镜→细准焦螺旋(5)污点位臵的判断:移动或转动法
4、原核细胞:没有核膜包围着的细胞核,无核膜和核仁。如细菌、蓝藻类、放线菌、乳酸菌等原核生物的细胞。
5、真核细胞:有核膜包围着的细胞核。如动物、植物和真菌(酵母菌、霉菌、食用菌)等真核生物的细胞。
6、细胞学说的建立和发展 :创立细胞学说的科学家是德国的施莱登和施旺。施旺、施莱登提出“一切动物和植物都是由细胞构成的,细胞是一切动植物的基本单位”。在此基础上德国的魏尔肖总结出:“细胞只能来自细胞”,细胞是一个相对独立的生命活动的基本单位。这被认为是对细胞学说的重要补充。
7、细胞中的大量元素是C、H、O、N、P、S、K、Ca、Mg。微量元素有Fe、Mn、B、Zn、Mo、Cu(铁猛碰新木桶)等。
8、组成生物体的基本元素:C元素。(碳原子间以共价键构成的碳链,碳链是生物构成生物大分子的基本骨架,称为有机物的碳骨架。)
9、缺乏必需元素可能导致疾病。如:缺铁性贫血,缺钙佝偻病,缺镁黄叶病,缺硼花而不实。
10、生物界与非生物界的统一性和差异性
统一性:组成生物体的化学元素,在无机自然界都可以找到,没有一种元素是生物界特有的,种类统一。
差异性:组成生物体的化学元素在生物体和自然界中含量相差很大。含量差异
11、细胞中的化合物包括无机物(水和无机盐)和有机物(糖、脂质、蛋白质和核酸)
12、氨基酸结构通式:
13、氨基酸的判断:至少有一个氨基和一个羧基连在同一个碳原子上。(组成蛋白质的20种氨基酸的区别:R基的不同)
14、蛋白质的元素组成:至少含有C、H、O、N,部分蛋白质还含有S、Cu等元素、基本组成单位:氨基酸(氨基酸约20种)
