根據生物某些特徵的存在來確定其它因素的現象，叫生物的指示現象，或指示作用。它們具有指示意義的某些特徵，稱為指示特徵(包括形態的、生理的、生物化學的等)。有氣候指示特徵的(如熱帶植物、寒帶植物)；有水指示現象的(人們在乾旱地區常藉助植物來找水源)；有土壤指示現象的(鐵芒箕是強酸性土壤的指示植物，鹼蓬指示鹼性土壤)；有地質指示現象的(湖北省黃石市就有一種草能指示地下有銅和鐵礦)；還有些植物對環境污染有指示作用，如矮牽牛花。 生物的指示作用表明，各個自然地理要素之間處於緊密相互聯系、相互依賴的關系之中。掌握了它們之間有規律的聯系，就有可能利用一個要素的特徵去認識另一個要素的存在。 從理論上講，地球上最初產生地殼，之後形成大氣圈、水圈，最後出現植被、土壤和動物界。因而，愈是年老的(即先產生的)要素對其它年青的(即後產生的)要素影響愈大；愈是年青的的要素對其它年老的要素依賴性愈大。正是這些獨立性最小而依賴性最大的要素具有最大指示意義。所以，後出現的植物對其它要素的影響具有很大的表現能力。 地球上的生命界可以劃分成不同的層次或組織水平。從大分子有機物開始直到生物圈，復雜程度逐級增加。當從一個層次過渡到另一個較高層次時，生命組織便會出現前一級所不具有的新性質和特徵。 生物存在於地理環境之中的，它們在個體發育的全部過程中，經常不斷地與環境間進行著物質與能量的交換。它從環境中取得必需的能源和營養物質，建造自己的軀體，同時又把不需要的代謝產物排放到外界環境中，以此維持其正常的生命活動和種族的繁續。因此，任何生物有機體都不能脫離環境而生存。環境控制和塑造著生物的生理過程、形態構造和地理分布。 在環境對生物發生影響的同時，生物有機體，特別是它們的群體也對環境產生相當明顯的改造作用。針葉林下土壤的酸度往往比同一地區闊葉林下的要高些。湖泊中浮游生物大量繁殖時，導致水體透明度下降，從而改變水中的光照條件。從更長遠的時間尺度看，生物還參與岩石的風化，地形的改變和土壤的形成，以及某些岩石和礦床的建造。水土流失可以用植物來防治，流動的沙丘可以用喬木、灌木和草本植物來固定。 在環境中對生物的生命活動起直接作用的那些環境要素叫做生態因素，如日光、熱、水、風、礦物鹽類和其他生物等。地形、海拔高度等則屬於間接起作用的因素，它們通過改變氣候、土壤等條件而對生物產生影響。 各個生態因素並不是孤立地、單獨地對生物發生作用，而是共同綜合在一起對生物產生影響，一個生態因素不管它對生物的生存有多麼重要，也只能在有其他因素的適當配合下才能發揮其作用。 生物或其群體具體居住地段的所有生態因素的總體叫做生境。由於地表各地氣候、土壤、岩性和地形等條件不同，形成極其多種多樣的生境類型，這正是地球上生物種類和其群體類型復雜多變的主要原因之一。 地球上各種生態因素的變動幅度非常廣闊，每種生物所能適應的范圍卻有一定的限度。如果當一個或幾個生態因素的量或質低於或高於生物所能忍受的臨界限時，不管其他因素是否適合，生物的生長發育和繁殖都會受到影響，甚至引起死亡。這樣的生態因素稱作限制因素，它是最易阻撓和限制生物生存的因素。限制因素隨時間地點而變，也因生物種類而異。在乾旱和半乾旱地區，水分條件往往是植物生存的限制因素。在嚴重污染的水域中，有毒的污染物常常是水生生物生存的限制因素。在研究環境對生物的生態作用時，既要注意生態因素的綜合作用，又要找出在一定條件下影響生物生存的限制因素，為採取相應管理措施提供科學依據。 生物在其生存過程中，對生態因素的忍耐不僅有一個生態上限和下限，同時在它的耐性限度內還有一個比較小的生態上的最適范圍，在這里生物生長發育得最好。在自然界，生物種並非經常處於其最適生境條件下，因為生物間的相互作用和外界自然條件的變化，妨礙生物去利用最適宜的環境。不同的生物種對生態因素和環境的適應能力有差異。一般來說，對環境適應能力較強種類，其分布范圍較廣。

Today, the phone into the tens of thousands of households, do you know who invented the telephone?Baer, who is the inventor of the telephone. He was born in the UK in 1847, when young, with his father in deaf ecation, had wanted to make a kind of let the deaf use the eyes to see the sound machine. In 1873, the United States became professor of Boston University Baer, began to study in the same line to transmit many telegraph device -- multiple telegraph, and germination using current to the human voice is transmitted to the remote idea, make numerous hills and streams are separated by people like to talk face to face. Then, Baer began a phone research. It was in June 2, 1875, Baer and his assistant Watson respectively in the two room test multiple telegraph, an accidental incidents inspired Baer. Watson room Telegraph has a spring stick to the magnet, Watson opened the spring, spring has vibration. At the same time, Baer was surprised to find his room telegraph machine on the spring vibration, also makes a sound, is the current vibration from one room to another room. Baer's idea was wide open, he thus think: if people on the piece of iron to iron, sound will cause vibration; if the iron is placed behind a piece of magnet, iron sheet vibration inevitably in the electromagnet coil to generate big small current. The fluctuation of current along the wire to the distant, distant similar device does not happen the same vibration, do the same thing? That sound along the wire spread far away. This is not the dream of phone! Baer and Watson by new ideas made the telephone. In one experiment, a drop of sulfuric acid splashed onto Baer's lap, hurts him shouting:" Mr. Watson, I need you, please come here!" This sentence by telephone through a wire to Watson 's ears, call success! In March 7, 1876, Baer became the invention of the telephone patent. The life of Baer received 18 patents, and cooperation with others obtained 12 patents. He conceived of telephone lines are buried underground, or suspension in the air, it is connected to the housing, villages, factories ... ... In this way, any place can directly call. Today, Baer's vision has already become areality.翻譯：、 今天，手機進入千家萬戶，你知道誰發明了電話嗎？ 貝爾，誰是電話的發明者。他1847歲時出生於英國，與父親在聾啞教育時，曾想讓一種讓聾人用眼睛看聲音的機器。1873、美國波士頓大學教授貝爾，開始學習在同一條線上傳送許多電報設備--多條電報，並利用當前的聲音傳送到人類的聲音，使眾山和溪流被人們所喜歡面對面交談。然後，貝爾開始了電話研究。這是1875年6月2日，貝爾和他的助手華森分別在2個房間測試了多次電報，一個偶然的事件激發了貝爾。華森房有一個彈簧棒的磁鐵，華森打開春天，春天有振動。同時，貝爾驚訝地發現他的房間里的電報機上的彈簧振動，也使一個聲音，是目前振動從一個房間到另一個房間。貝爾的想法是敞開的，他因此認為：如果人們對鐵的一塊鐵，聲音會引起振動；如果把鐵放在一塊磁鐵，鐵片振動不可避免地在電磁鐵線圈產生大的小電流。電流沿導線的波動，遙遠的類似設備不發生相同的振動，做同樣的事情？那聲沿著電線傳得很遠。這不是夢的電話！ 貝爾和華森的新想法使電話。在一個實驗中，一滴硫酸濺到貝爾的大腿上，讓他大聲喊：「先生，我需要你，請你來這兒！」這句話用電話接通了一個電線，到了耳華的耳朵，叫成功！1876年3月7日，貝爾成為了電話專利的發明。 貝爾一生共獲得18項專利，與他人合作獲得了12項專利。他設想的電話線是埋在地下，或懸掛在空中，它被連接到房屋、村莊、工廠……這樣，任何地方都可以直接調用。今天，貝爾的眼光已經變成了一個現實。

垃圾收集是20世紀後期，環境保護作為一項最成功的例子。今天，路的垃圾回收計劃已經觸及大多數人在美國。事實上，傢具垃圾回收比那些參加投票活動。在全國范圍內，老百姓在他們的努力帶來了很多的物理材料。垃圾回收，包括堆肥1996年改變了命運的原始材料進入廢物的填充或焚燒爐5700噸，這一數據在1990年到3400萬噸 - 僅僅六年時間增加了67％。垃圾回收和堆肥材料的加工轉化率，預計到2005年的8500萬噸，即35％的固體廢物全部。要理解這個數字，想像力充滿了再生材料，3英尺長（27立方英尺）箱逐一推為一體，形成整齊地從地球到月球的橋梁。在1996年，這些箱子最多可以有3/4的橋梁。當我們在2005年實現35％的回收目標，以填補盒可回收物能夠到達月球。垃圾收集是值得所有的努力，你呢？創造利潤的底線嗎？一些觀察家認為，眼前的利潤是成功的唯一標准。這種觀點只考慮單獨的恢復計劃如何影響一個社會的廢物管理費用，而造成的浪費填充或焚燒爐的成本都發送到另一個即將到來的。其他一些觀察家認為，用更廣闊的視野上的成本與效益的廢物回收。
雖然大部分的廢物回收計劃的成功經驗是不同的，但是，包括許多高級垃圾轉化率的計劃在經濟上可行，不創造利潤。回收品市場不可避免的起伏。效率的垃圾收集計劃必須繼續改善，以防止垃圾收集機制，在一定程度上激烈的市場擺動的影響。在未來的十年中，社會參與的垃圾收集的目標之一是確定和復制傳播決定成功的因素。
國家特別重要的是，在努力學習，並採取最有效的垃圾回收程序，然後使用的垃圾收集方式已經做了很多的經濟和環境效益。的好處很多細致的觀察員似乎是顯而易見的，因為很難理解市級會計核算和稅務特性，或不能反映在市場上的城市和垃圾收集人員的合同價格。例如，總能量飲料容器回收節約固體廢物回收的好處是不包括在道路垃圾收集合同談判價格的，由自治區管理，如工業廢水，建築廢墟，被拆毀的廢墟和農業同樣適用於廢物等，以及其他垃圾回收的主機。從這些原料中恢復過來，還可以提高地球和子孫後代的可持續發展。的好處
回收固體廢物至少可以分為八類。回收：
*，以減少對化肥的需求填充的地方;
防止空氣污染和睡眠污染排放的各種
節約能源;
提供有價值的原材料，工業生產和創造就業機會;
*
以減少溫室氣體的排放量;
促進環保技術的發明;
*為子孫後代保留的資源。
在20世紀70年代和90年代，垃圾回收行業是一個增長的行業。垃圾收集是一個熱潮。在1996年，7000多名在路上的垃圾收集項目約一半的美國人。年，包括堆肥的垃圾收集，轉移27％ - 超過1/4--國家固體廢物的下落。
垃圾回收是不是新的，因為記錄的歷史上，它有。在大規模生產前，每個家庭在通常的維修，再利用和再循環的材料，這是經濟發展的需要。例如，就目前而言，產業的命脈，依靠回收，直到19世紀後期，抹布造紙行業纖維的主要來源。零售商收集回收的海運集裝箱壓扁的金屬盒。廢舊廠房已經有效地回收利用舊汽車，汽車零部件和其他金屬物體。第一次世界大戰和第二次世界大戰的垃圾回收事業帶來了短暫的繁榮，因為垃圾收集車收集廢紙，金屬及其他材料，以支持戰爭。戰爭結束後，腐爛的垃圾收集車。每一個家庭在20世紀60年代末，垃圾回收水平和參與率在整個下降到最低點。傳統的垃圾回收，但也因為美國在20世紀，大部分的經濟在衰退暴漲。收入增加，大批量生產的項目，價格實惠，日益豐富的物質生活的人。豐富帶來了不斷增長的趨勢 - 產品廢棄後初次使用或更換，而不是重新使用或回收。
早期的環境激進主義和環保意識的熱潮始於20世紀70年代帶來了一陣廢物循環再造的興趣。隨後在1970年，第一屆地球日，3000垃圾回收志願者中心開幕。在20世紀70年代初，進行了一百多道垃圾收集計劃，其中許多將專注於回收的材料，如報紙和瓶子，和一個系列的。在垃圾回收和志願者活動的日益濃厚的興趣。美國環境保護署和國家環保總局制訂指導原則提供技術援助，以及該地區設定的目標努力。盡管在20世紀70年代的垃圾產生了25％的增長，但同比增長45％，廢物回收利用。
廢料填開始在20世紀80年代的不足，尤其是在人口密集的地區，從而導致經常要舍棄掉的長途運輸跨越州際線。廢物管理公司開始回收計劃，這往往是與新的焚化爐的建議和廢料填充地。以社區為基礎的組織通常被稱為上投入更大的努力，希望限制或避免新的廢物處置設施。國家和地區的政府也越來越多地活躍在廢物管理計劃，包括擴大回收和堆肥。肥料填補短缺抵制的州際垃圾，國家的崛起，關注廢物管理的共同作用下，美國環保局公布的國家政策指導方針 - 於1989年的「行動綱領」，呼籲美國人達到25％，垃圾回收利用率。然後，約1000道路垃圾收集計劃，廢物回收站，廢物處理廠也工作。廢物的產生在20世紀80年代和再次快速增長，同比增長近36％，在10年，但所產生的廢物總量的16％，飆升近132％，占垃圾回收和堆肥結合。回收情況得到改善，回收材料公司在美國建立生產比現有的材料。 20世紀90年代，該行業已投入了數百萬美元的加工和製造技術，這些技術專門用於修復材料的使用，產生了廣泛的產品類型，而不是利用未使用的原料。消費者也有利於深刻認識到，自己買的手機產品回收和材料，他們在垃圾回收中發揮了重要的作用。各級政府部門也發揮了作用，提高政府采購的產品回收物，以確保回收的活力。垃圾收集使用保持了兩位數的增長，1990年至1997年，以達到回收率達27％，預計產生的廢物 - 與1990年相比增加了近67％，超過25％的國際政策目標。可以看出，在全國的許多城市和城鎮參與廢物回收利用的趨勢。只舉一個例子，安阿伯，密歇根州，是一個在20世紀70年代由志願者和社區建立一個廢物回收站。幾年後，回收安阿伯開始了道路的垃圾收集計劃的志願者組織。今天，安阿伯市人民政府向公眾收集了23可回收物一周，每季度庭院遺址收集的廢物四類。這些努力，再加上戶家庭堆肥，廢物回收和密歇根集裝箱處理運動的影響，將安阿伯讓我們將52％的垃圾。提供廢物回收服務，回收安阿伯市重合同投標一貫贏了。
大量的垃圾轉換，將有助於降低成本。例如，在1996年，安阿伯，費用為71元一噸垃圾的回收和堆肥相比，噸的垃圾收集和處理成本的86％。
像垃圾一樣安阿伯的轉換率，低成本的社區提供了一個模式，努力提高該地區的垃圾回收計劃，在全國的經濟可行性。

a,b,b,c,d,1,科技英語閱讀4
The invention of the incandescent (白熾的) light bulb by Thomas Edison in 1879 created a demand for a cheap,readily available (可利用的) fuel with which to generate large amounts of electric power.Coal seemed to fit the bill,and it fueled (供以燃料) the earliest power stations (which were set up at the end of the nineteenth century by Edison himself).As more power plants (發電物棗廠) were constructed throughout the country,the reliance (依靠) on coal increased.Since the First World War,coal-fired power plants have accounted for about half of the electricity proced in the United States each year.In 1986 such plants had a bined capacity (產量) of 289 000 megawatts and consumed (消耗散陵) 83 percent of the nearly 900 million tons of coal mined in the country that year.Given (考慮到沖螞戚) the uncertainty in the future growth of nuclear power and in the supply of oil and natural gas,coal-fired power plants could well provide up to 70 percent of the electric power in the United States by the end of the century.
Yet,in spite of the face that coal has long been a source of electricity and may remain one for many years (coal represents about 80 percent of the United States fossil-fuel reserves,it has actually never been the most desirable fossil fuel for power plants.Coal contains less energy per unit of weight than natural gas or oil; it is difficult to transport,and it is associated with a host of environmental issues among them acid rain.Since the late 1960s problems of emission (散發) control and waste disposal have sharply reced the appeal of coal-fired power plants.The cost of ameliorating (改進) these environmental problems,along with the rising cost of building a facility (設備) as large and plex as a coal-fired power plant,has also made such plants less attractive from a purely economic perspective (觀點).
Changes in the technological base of coal-fired power plants could restore (恢復) their attractiveness,however.Whereas some of these changes are evolutionary (進化的) and are intended mainly to increase the proctivity of existing plants,pletely new technologies for burning coal cleanly are also being developed.
31.What is the main idea of the passage?
a.Coal-fired plants are an important source of electricity in the United States and are likely to remain so.
b.Generating electricity from coal is paratively recent in the United States.

32.Edison』s electric light bulb is mentioned in the passage because it .
a.replaced gas as a light source
b.increased the need for electrical power
c.was safer than any other method of lighting
d.could work only with electricity generated from coal
33.It can be inferred from the passage that coal became the principal source (主要的來源) of electricity in the United States because it .
a.required no plicated machinery (復雜的機械)
b.was paratively (相對的)plentiful and inexpensive
c.was easy to transport
d.burned efficiently
34.In the author』s opinion,the importance of coal-generated electricity could increase in the future for which of the following reasons?
a.The possible substitutes (代替物) are too dangerous.
b.The cost of changing to other fuels is uncertain
c.The future availability (可用性) of other fuels is uncertain.
d.Other fuels present too manyenvironmental problems.
35.According to the passage,which of the following is one of the goals of the new technology in coal-fired plants?
a.To adapt (使適應) ,the plants to other kinds of fuel.
b.To rece the cost of building more plants.
c.To lengthen the lives of plants already in use.
d.To make the plants already in use more proctive.

Some scientists say that animals in the ocean are increasingly threatened(威脅)by noise pollution caused by human beings..
The noise that affects（影響） sea creatures comes from a number of human activities. It is caused mainly by instrial underwater explosions（爆炸）, ocean drilling, and ship engines. Such noises are added to natural sounds include the breaking of ice fields, underwater earthquakes, and sounds made by animals themselves.
Decibels (分貝 measured in water are different those measure on land. A noise of one hundred and twenty decibels on land causes pain to human ears. In water, a decibels level of one hundred and ninety-five would have the same effect.
Some scientists have proposed（提議）setting a noise limit of one hundred and twenty decibels in oceans. They have observed that noises at that level can frighten and confuse whales（鯨魚）.
A team of American and Canadian scientists discovered that louder noises can seriously injure some animals. The research team found that powerful underwater explosion were causing whales in the area to lose their hearing. This seriously affected the whales』 ability to exchange information and find their way. Some of the whales even died. The explosion had caused their ears to bleed（流血）and become infected（感染）.
Many researchers whose work depends on ocean sounds object to(反對) to a limit of one hundred and twenty decibels. They say such a limit would mean an end to important instrial and scientific research.
Scientists do not know how much and what kind of noises are harmful to ocean animals. However, many scientists suspect(認為，懷疑) that noise is a greater danger than they believed. They want to prevent noises from harming creatures in the ocean.

科技豐富生活初中英語作文 篇3
The development of modern technology has made peoples life more complexso people should choose to have a simple and easy life without using technology.To what extent do you agree or disagree?
Give reasons for your answer and include relevant examples from your knowledge or experience.
The advancement of modern technology is making peoples life more comfortable and at the same time less human.To those who enjoy the benefits of technologythere is no better time to be alive than nowbut to others life has been increasingly complex and stressful.The issue is whether such new technological machines as computers and the Internet would be our servants forever or eventually could become our masters.
All kinds of inventions made possible by technology are designed to be the slaves of human beingsif human beings are not to be slaved by machines.Once upon a timewe were plain peoplebut that was before we began having relationships with technological systems.By getting involved with computerized machineswe could not help changing the way we live and the way we workfor better or for worse It can be realized that life is more complex because much of modern technology is not born to meet primary human needsand many "unnecessary" inventions are procing negative effects on a living style that used to be relatively simple.Thusthere is an overwhelming feeling of complexity in the sense that machines act like humans and humans act like machines.Now that "intelligent" machines such as robots are widely applied to take the place of human beings because they are capable of doing many useful jobsalthough making many people jobless.Those who cannot work with computers are disadvantaged and therefore helpless while the traditional skills and simple ways of life are fading awaynever to return again.現代科技的發展使人們的生活更加復雜，人們應該選擇一種簡單而不使用技術的生活，你在多大程度上同意或不同意?
給出你的答案的原因，並從你的知識或經驗包括相關的例子。
現代信息技術的發展使人們的生活更舒適，同時減少人力。對那些喜歡技術的好處，有沒有更好的時間比現在還活著，但是別人的生活已經越來越復雜和緊張。問題是，電腦和互聯網這樣的新技術設備將我們的僕人永遠或最終能成為我們的主人。
各種各樣的發明成為可能的技術設計是人類的奴隸，如果人類不被奴役的機器，曾幾何時，我們是普通人，但那是在我們開始有技術系統之間的關系。通過參與計算機的機器，我們不能改變我們的我們的工作和生活方式，或好或壞的可以實現的，生活是更復雜的因為許多現代科技並不是生來要滿足主人的需要，許多「不必要」的發明是產生在生活方式使用的是相對簡單的負面影響。因此，這是一種無法抗拒的復雜的感覺，機器像人類的感覺像馬中國現在的「智能」的機器如機器人，是因為他們有能力做了許多有益的工作，廣泛應用於取代人類，雖然使許多人失業。那些不能用電腦工作都處於弱勢，因此無奈而傳統技能和簡單的生活方式都消失了，再也回不來了再次。
