      判斷下文摘自研究論文的哪個(gè)部分,并分析其結(jié)構(gòu)和每句話的作用。

      Result—結(jié)果:

      Table 11 shows the number of years to complete a doctoral program for both U.S.and international students at a major research university.As can be seen, international students on average complete doctoral programs in less time than U.S.students in all divisions.The difference in years to completion ranges from a relatively low 0.3 years in physical sciences/engineering and humanities/ arts to a high of 2.8 years in individual departmental programs.Discussion—討論:

      The consistent difference in time to degree is not fully understood at present.However, one key factor may be motivation.Many international students have considerable external pressures,including sponsorship/scholarship restrictions, family obligations, and employer demands, which could influence the length of time it takes to earn a doctorate.根據(jù)下列各段話的內(nèi)容和語(yǔ)言特點(diǎn),判斷各段話分別摘自研究論文正文中的哪個(gè)部分 Method—方法:

      Male red-winged blackbirds were recorded and observed.Analog tape-recordings of vocalizations were completed and territorial behaviors were monitored for each subject during three separate 30 minute observation periods.Females were observed in each subject's territory during recording.Individual territories and perching positions were mapped for each subject.Result—方法:

      From the 41 responses received, only 5 were form schools whose students only completed team projects.32 responses were from school whose students completed only individual projects.This is reflected in the high frequency of disagree and strongly disagree responses to question 28(see Table1).Method—方法:

      A copy of the questionnaire can be seen in Fig.1.The questions were designed to match each of the eight goals and five methods for science as defined in this study.The questions were then examined by several professional educators in the field of science.The viewers' comments were used to develop questions for each goal.The experts' opinions were in agreement that the final version of the questionnaire was worded appropriately and that the content of the questions matched these goals for science education.Discussion—討論:

      Science projects were rated overwhelmingly and consistently positive on each of the eight educational goals for science.In the minds of the teachers, science projects are an effective way to address the new educational goals.The rating frequencies show that teachers think science projects are especially effective in incorporating hands-on/minds-on science.Result—結(jié)果:

      The analysis shows 52 % of the graduates used their exhibits at events in their county(Fig.4)。Many graduates(64 %)collected water samples in their county,56 % established a water sample collection point in their county for transport to a water testing lab,and 48 % demonstrated sample collection.Discussion—討論:

      The plants produce viable shoot sections, which are capable of growth and may serve as vegetative propagules(繁殖體)。Development of new tissues is a clear sign of healthy,growing shoot sections and indicates that the sections could go on to produce mature plants if left undisturbed.Under our growth conditions,80% of shoot sections could have matured into seed-producing plants.在下列句中增加或替換適當(dāng)?shù)脑~,以減弱句子的語(yǔ)氣:

      1.The experience of older students is not necessary to be more successful with a science project.將劃線部分改為 may not be

      2.One explanation for these differences is that teachers who most strongly believe science projects are valuable encourage their students to work harder and encourage them to go to science fair.將劃線部分改為One possible explanation

      3.However, additional training is needed in disinfection alternatives, iron and hydrogen sulfide removal,and proper well construction.將劃線部分改為 may be needed

      4.Some fluctuation is inevitable,since only less than 20 students took the qualifying exam each year.將劃線部分改為is probably inevitable

      5.As can be seen,the pass rate fluctuated quite widely.將劃線部分改為appeared/seemed to fluctuate

      6.From 1989 until the end of the period covered,pass rates have steadily climbed.將劃線部分改為appeared/seemed to have steadily climbed

      7.Other factors are the amount of research funding,the quality of the students themselves,and the priority given to doctoral funding.將劃線部分改為Other possible factors

      8.In fact,the pass rate is cyclical.將劃線部分改為 seems to be cyclical

      9.Even so,the fact that 10 out of 15 students passed in 1985 caused the department to try and reduce its number of doctoral students the following year.將劃線部分改為 probably caused

      10.The overall results prove that the Quality Water for Home and Farm correspondence program met the objectives set for the program and was an effective method to deliver water quality and management training.將劃線部分改為 indicate

      III.Sentence Translation:

      A.Translate the following English sentences into Chinese:(Pay attention to the underlined part)

      1.博弈的實(shí)質(zhì)是博弈者采取策略之間的相互依賴性。這種策略性的相互依賴表現(xiàn)為兩個(gè)不同的類別:連續(xù)策略之間的相互作用以及聯(lián)立策略之間的相互作用。

      2.當(dāng)我們把博弈的結(jié)果表述為一種均衡的時(shí)候,并不是基于以下的假設(shè):即博弈的每個(gè)參與者的個(gè)人最佳策略將會(huì)帶來(lái)共同的最優(yōu)化結(jié)果。

      3.在一些博弈的沖突中,任何條理化和計(jì)劃性的行為都會(huì)被對(duì)手發(fā)現(xiàn)并加以利用。因此,通過(guò)采用組合性策略使對(duì)手迷惑就顯的非常重要。我們?cè)隗w育運(yùn)動(dòng)中可以發(fā)現(xiàn)典型的例子---比如足球比賽時(shí)特定情況下選擇跑位或傳球,網(wǎng)球比賽擊球時(shí)選擇斜線球或底線球。

      4.邊緣政策 “是一種故意使局勢(shì)變的有些無(wú)法控制的策略,正是這種無(wú)法控制性可能會(huì)使另一方無(wú)法接受而選擇妥協(xié)?!?/p>

      5.當(dāng)博弈的一方了解其他人所不掌握的信息時(shí),他會(huì)急于隱瞞這一信息(比如牌局中所拿到的牌),在其他一些情況下,他還會(huì)想令人信服的公開某些信息(比如某一公司對(duì)質(zhì)量的承諾)。在這兩種情況下,行勝于言是博弈者遵循的基本原則。

      Para1 博弈是有關(guān)策略的科學(xué)。它試圖以數(shù)學(xué)和邏輯的方法來(lái)幫助博弈者作出決策,在一系列紛繁復(fù)雜的博弈中應(yīng)采取何種策略來(lái)保證自己獲得最大利益。博弈論研究的博弈的范圍包括了從下棋到撫育兒童,從網(wǎng)球競(jìng)技到公司轉(zhuǎn)手。但是所有的博弈都具有一個(gè)共同的特征:相互作用。也就是說(shuō),每一個(gè)博弈者的博弈結(jié)果取決于所有博弈參與者的策略選擇。在零和博弈中,博弈者的利益之間是完全沖突的,因此一方的得利必然導(dǎo)致另一方的損失。更多具有代表性的例子還有會(huì)導(dǎo)致共同得利(正和)博弈和共同損失(負(fù)和)博弈,同樣的情況還會(huì)發(fā)生在另外一些沖突中。

      Para2博弈論研究的先驅(qū)者是普林斯頓數(shù)學(xué)家約翰?馮?諾依曼。在早先的一段時(shí)間里,研究的重點(diǎn)被放在了完全沖突(零和)博弈(非合作博弈)上,其他的博弈當(dāng)時(shí)被認(rèn)為是以合作形式出現(xiàn)。也就是說(shuō),博弈要求參與者共同地選擇和實(shí)施他們的行為.最近的研究則把重點(diǎn)放在了那些既不屬于零和博弈也不屬于絕對(duì)合作博弈的情況上,在這些博弈中,博弈者自主地選擇博弈行為,但他們之間的相互關(guān)系中充滿了合作與競(jìng)爭(zhēng)。

      Para7與連續(xù)策略博弈的線形思維不同的是,采取共發(fā)性策略的博弈要求邏輯思維。在忽略其他參與者當(dāng)前策略的情況下,盡管博弈者們同時(shí)采取行動(dòng),每一個(gè)參與者必須清楚的意識(shí)同時(shí)還會(huì)有其他的參與者在依次關(guān)注整個(gè)博弈過(guò)程。這時(shí)的思維模式可描述為:我想他認(rèn)為我會(huì)這樣考慮?。因此,博弈者必須從全體博弈者的立場(chǎng)出發(fā)并努力判斷出最終的博弈結(jié)果。每個(gè)參與者的個(gè)人最佳行為都是全局謀劃中不可或缺的一部分。

      Para8運(yùn)用普林斯頓數(shù)學(xué)家約翰?納什提出的均衡概念,可以推導(dǎo)出這種邏輯思維的結(jié)論。我們尋求一系列的策略組合,每個(gè)博弈者都會(huì)有自己的選擇,當(dāng)所有的對(duì)手們?cè)趯?shí)施他們決定的最佳策略時(shí),我們所做的選擇應(yīng)該對(duì)自己是最有利的。換句話說(shuō),每個(gè)博弈者都會(huì)對(duì)其他人的策略作出最優(yōu)化的應(yīng)對(duì)。

      Para9有時(shí), 無(wú)論其他博弈者如何行動(dòng),博弈的一方的最佳策略組合始終如一,這被稱作這一博弈者的優(yōu)策略。在其他情況下,如果博弈者的策略始終于己不利,則被稱作劣策略,其含義是指無(wú)論其他博弈者如何行動(dòng),對(duì)手的策略總是優(yōu)于自己。因此,謀求策略均衡應(yīng)該從尋找優(yōu)策略和消除劣策略開始。

      Para15戰(zhàn)略性行動(dòng)。博弈者可以通過(guò)運(yùn)用威嚇和許諾來(lái)改變其他對(duì)手對(duì)其行動(dòng)的預(yù)測(cè),從而誘使他們采取對(duì)其有利的行為或改變他們對(duì)己不利的行為。為了取得成功,威嚇和許諾必須是可信的。這往往會(huì)導(dǎo)致出現(xiàn)一些問題,原因就在于當(dāng)需要采取以上策略時(shí),通常實(shí)施威嚇和許諾而獲益往往會(huì)付出較大的代價(jià)。博弈論研究幾種提高可信度的方法,一個(gè)基本的原則就是威嚇和許諾要在符合博弈者利益的前提下減少自身未來(lái)行動(dòng)的自由度。通過(guò)這樣的方式,博弈者可以避免自己違背承諾,或者避免產(chǎn)生對(duì)對(duì)手冒犯的縱容。

      Para16例如,當(dāng)柯臺(tái)斯到墨西哥后,燒掉了戰(zhàn)船,故意沒有給自己留下撤軍的退路。由于沒有返城的船只,柯臺(tái)斯面對(duì)的只有戰(zhàn)勝并征服對(duì)手或被對(duì)手消滅掉兩種可能。盡管他的士兵在數(shù)量上處于絕對(duì)劣勢(shì),但這種血戰(zhàn)至死的威脅使得對(duì)手的士氣變的低落,印第安軍隊(duì)面對(duì)這樣意志堅(jiān)定的對(duì)手時(shí),他們選擇了退卻。寶麗來(lái)公司在拒絕共享即時(shí)成像市場(chǎng)時(shí)也采取了類似的策略,當(dāng)時(shí)它決定與任何擠占該市場(chǎng)的對(duì)手拼個(gè)你死我活。當(dāng)柯達(dá)公司試圖染指即時(shí)成像業(yè)時(shí),寶麗來(lái)調(diào)動(dòng)了所有的資源進(jìn)行反擊。14 年后, 寶麗來(lái)公司在與柯達(dá)公司的訴訟中獲勝,重新贏得了在即時(shí)成像市場(chǎng)的壟斷地位。

      Para17使威嚇變得可信的另一個(gè)方法是運(yùn)用冒險(xiǎn)性的邊緣化策略,這一策略的風(fēng)險(xiǎn)在于: 如果其他博弈者未能按照威嚇的要求去做的話,結(jié)果對(duì)大家將是一損俱損。托馬斯?謝林在他的《沖突策略》一書中介紹說(shuō),邊緣化策略就是故意使局勢(shì)變的無(wú)法控制的策略,正是由于局勢(shì)的無(wú)法收拾可能令其他對(duì)手難以接受,從而迫使對(duì)手作出妥協(xié)。

      Para5無(wú)線技術(shù)和 IP 電話對(duì) E911 提出了獨(dú)特的挑戰(zhàn)。因?yàn)槭謾C(jī)用戶可以漫游,所以要準(zhǔn)確確定其位置需要新的方法和技術(shù)。更大的問題是:從無(wú)線話機(jī)發(fā)出的緊急呼叫有可能不會(huì)被轉(zhuǎn)接到最近的 911 中心。即便能夠做到這一點(diǎn),工作人員也不會(huì)得到主叫號(hào)碼或主叫的位置。工作人員必須花費(fèi)寶貴的時(shí)間盡量讓主叫人給出地址,而前提條件是主叫人必須知道自己所在位置,還要能夠說(shuō)得出話來(lái)。估計(jì)在 4500 萬(wàn) 911 的呼叫中,有 30%是用無(wú)線話機(jī)撥打的,所以建造可靠的無(wú)線 E911 基礎(chǔ)設(shè)施至關(guān)重要。

      Para6在蜂窩網(wǎng)絡(luò)中布設(shè) 911 是通過(guò)三個(gè)階段進(jìn)行的。第一階段,也是目前所處的階段,也被稱作無(wú)線階段 0:確保 911 呼叫能夠轉(zhuǎn)接到一個(gè)緊急通信受理中心,不必要是最近的緊急通信受理中心。無(wú)線階段 1:緊急通信受理中心會(huì)獲得主叫的回?fù)芴?hào)碼,這在通話意外中斷時(shí)很有意義。無(wú)線階段 2:向 911 工作人員提供主叫電話號(hào)碼和主叫的位置信息。Para7今天,在美國(guó) 79%的州已經(jīng)在其 80%的縣布設(shè)了有線 E911。比較而言,50%已完成無(wú)線階段 1,而只有 18%的州在 80%的縣布設(shè)了無(wú)線階段 2。

      Para10VoIP E911 服務(wù)的計(jì)劃已經(jīng)確定,也是通過(guò)三個(gè)階段來(lái)實(shí)施。階段一,或通常稱為 I1 解決階段,詳細(xì)說(shuō)明住宅或零售 VoIP 911 呼叫會(huì)通過(guò)公共電話交換網(wǎng)絡(luò)、電纜或競(jìng)爭(zhēng)性的 本地交換運(yùn)營(yíng)商轉(zhuǎn)接到當(dāng)?shù)氐木o急通信受理中心。階段二,或稱 I2,會(huì)通過(guò)公共電話交換 網(wǎng)絡(luò)為 IP 電話提供完整的 E911 服務(wù)。布設(shè)的第三階段,或稱 I3,會(huì)把 E911 承載到 IP,也包括沒有電話號(hào)碼的設(shè)備。

      Para11正在討論許多種讓服務(wù)提供商為 E911 服務(wù)查明 IP 電話的位置信息的方法,但美國(guó)通信委員會(huì)就此還沒有提出明確的方向。布賴恩?羅森先生,負(fù)責(zé)馬可尼公司寬帶路由和交換部門的前副總裁,也是一家剛剛創(chuàng)建的生產(chǎn)下一代緊急通信受理中心基礎(chǔ)設(shè)施的埃莫治可姆公司的創(chuàng)始人,他認(rèn)為解決方案必須包括技術(shù)和法規(guī)兩個(gè)方面。他指出接入基礎(chǔ)設(shè)施提供商,即擁有數(shù)字用戶線路、電纜和無(wú)限保真網(wǎng)服務(wù)的實(shí)體總能確定設(shè)備在網(wǎng)絡(luò)上的位置。問題是要把位置信息傳遞給應(yīng)用服務(wù)提供商、IP 電話運(yùn)營(yíng)商或企業(yè)。羅森認(rèn)為應(yīng)向接入基礎(chǔ)設(shè)施提供商征稅支付 E911 服務(wù)費(fèi)用,就像在有線網(wǎng)絡(luò)中一樣。通過(guò)把費(fèi)用轉(zhuǎn)移給應(yīng)用服務(wù)提供商的方法可以補(bǔ)足應(yīng)用服務(wù)提供商的成本開銷,也實(shí)現(xiàn)了對(duì)終端用戶的收費(fèi)。

      Para15三角測(cè)量比簡(jiǎn)單的使用電話接入點(diǎn)定位更進(jìn)了一步。通過(guò)對(duì)比多個(gè)接入點(diǎn)的信號(hào)強(qiáng)度,三角測(cè)量能更精確定位用戶。問題是三角測(cè)量在電話與多個(gè)基站相連的蜂窩網(wǎng)絡(luò)中頗為有 效,但無(wú)限保真網(wǎng)的協(xié)議卻是為接入單個(gè)接入點(diǎn)而設(shè)計(jì)的。蜂窩網(wǎng)絡(luò)在已獲授權(quán)波段工作,而無(wú)限保真網(wǎng)絡(luò)使用的是未授權(quán)的波段,因此其他設(shè)備的干擾會(huì)使三角測(cè)量難以進(jìn)行。

      1、They can be used for a very wide range of applications, from assisting the very large-scale electrical grid down to tiny portable devices used for many purposes.他們可以被使用于非常廣泛的應(yīng)用,從協(xié)助非常大規(guī)模的電網(wǎng)到微型便攜設(shè)備用于許多目的。

      2、When considering the use of electrochemical energy storage systems in various applications, it is important to be aware of the properties that might be relevant, for they are not always the same in every case.當(dāng)考慮使用電化學(xué)儲(chǔ)能系統(tǒng)在各種應(yīng)用程序中,重要的是要注意的屬性可能是相關(guān)的,因?yàn)樗麄儾⒉豢偸窍嗤脑诿恳粋€(gè)案例。

      3、A rule of thumb that was used for a number of the conventional aqueous electrolyte battery systems was that a practical cell could only produce about 1/5–1/4 of the maximum theoretical specific energy(MTSE).經(jīng)驗(yàn)法則是用于許多傳統(tǒng)的水電解質(zhì)電池系統(tǒng)是一個(gè)實(shí)際的細(xì)胞只能產(chǎn)生大約1/5-1/4的最大理論具體能源(MTSE)。

      4、Electrochemical energy production is under serious consideration as an alternative energy/power source, as long as this energy consumption is designed to be more sustainable and more environmentally friendly.電化學(xué)能源生產(chǎn)正在認(rèn)真考慮作為替代能源/電源,只要這種能耗設(shè)計(jì)更可持續(xù)、更環(huán)保。

      5、Batteries are divided into two general classes: primary batteries that are discharged once and discarded;secondary, rechargeable batteries that can be discharged and then restored to their original condition by reversing the current flow through the cell.電池分為兩個(gè)一般類:一次電池放電一次,丟棄;二次可充電電池,可以放電,然后恢復(fù)到原來(lái)的狀態(tài)由逆向電流通過(guò)電池。

      6、這將是本文所示,一個(gè)可以理解的主要現(xiàn)象和問題在電化學(xué)系統(tǒng)中沒有詳細(xì)考慮他們真正的電化學(xué)特性。

      Although the energy storage and conversion mechanisms are different, there are “electrochemical similarities” of these three systems.10、這是一個(gè)物質(zhì),它的吸收太陽(yáng)輻射較低,因此,需要一層厚厚的硅高效吸收。

      It is a material with relatively low absorption of solar radiation, and, therefore, a thick layer of silicon is required for efficient absorption.III.Reading Comprehension Development of PV world markets in MWpeak(MWpeak is defined as power under

      full sun, approximately 1 kW/m2)

      There are two major market sectors, grid-connected and so-called standalone systems.The former delivers power directly to the grid.For this purpose the dc current from the solar modules is converted into ac by an inverter.The latter supplies power to decentralized systems and small-scale consumer products.A major market currently being developed is in solar home systems, supplying basic electricity demand of rural population in developing countries.The magnitude of this task can be appreciated if one is aware that about 2 billion persons are without access to electricity today.At present, both markets need subsidies, the grid-connected installations because PV is much more costly than grid electricity, and solar home systems because the potential users lack the investment capital.On the other hand, there is also a significant industrial stand-alone market that today is fully economical.Because of its high potential, the market is hotly contested and new companies are entering constantly.It is significant that several large oil companies have now established firm footholds in photovoltaics.Indeed, a recent study of possible future energy scenarios up to the year 2060 published by the Shell company predicts a multigigawatt energy production by renewable energies, including photovoltaics.On the other hand, the strong competition leads to very low profit margins of most participants of this market.Starting in 2000, the market showed an accelerated growth of more than 30%.There are good chances that this growth will continue for at least some years because some countries have adopted aggressive measures to stimulate the grid-connected market, as mentioned above.In order to meet the growing demand, many PV companies are in the process of setting up substantial new cell and module production capacities.1、What is the solar home systems’ purpose and the magnitude of it? supplying basic electricity demand of rural population in developing countries.The magnitude of this task can be appreciated if one is aware that about 2 billion persons are without access to electricity today.2、What are two major market sector? And introduce them simply.There are two major market sectors, grid-connected and so-called standalone systems.The former delivers power directly to the grid.For this purpose the dc current from the solar modules is converted into ac by an inverter.The latter supplies power to decentralized systems and small-scale consumer products.3、Why we can say the market has good prospects?

      Starting in 2000, the market showed an accelerated growth of more than 30% and some countries have adopted aggressive measures to stimulate the grid-connected market, as mentioned above.

      大學(xué)生活就像喝可樂。我的感受。我知道,我喜歡它!youth youth is not a time of life;it is a state of mind;it is not a matter of rosy cheeks, red lips and supple knees;it is a matter of the will, a quality of the imagination, a vigor of the emotions;it is the freshness of the deep springs of life.youth means a temperamental predominance of courage over timidity of the appetite, for adventure over the love of ease.this often exists in a man of sixty more than a body of twenty.nobody grows old merely by a number of years.we grow old by deserting our ideals.years may wrinkle the skin, but to give up enthusiasm wrinkles the soul.worry, fear, self-distrust bows the heart and turns the spirit back to dust.whether sixty or sixteen, there is in every human beings heart the lure of wonder, the unfailing child-like appetite of whats next, and the joy of the game of living.in the center of your heart and my heart there is a wireless station;so long as it receives messages of beauty, hope, cheer, courage and power from men and from the infinite, so long are you young.when the aerials are down, and your spirit is covered with snows of cynicism and the ice of pessimism, then you are grown old, even at twenty, but as long as your aerials are up, to catch the waves of optimism, there is hope you may die young at eighty.其他回答 共4條 pain past is pleasure.過(guò)去的痛苦即快樂。all things are difficult before they are easy.凡事必先難后易。nothing is impossible to a willing heart.心之所愿,無(wú)事不成。where there is life, there is hope.有生命必有希望。i feel strongly that i can make it.我堅(jiān)信我一定能成功。better to light one candle than to curse the darkness.與其詛咒黑暗,不如燃起蠟燭。the shortest answer is doing.最簡(jiǎn)短的回答就是行動(dòng)。four short words sum up what has lifted most successful individuals above the crowd: a little bit more.成功的秘訣就是四個(gè)簡(jiǎn)單的字:多一點(diǎn)點(diǎn)。(凡事比別人多一點(diǎn)點(diǎn)!多一點(diǎn)努力,多一點(diǎn)自律,多一點(diǎn)實(shí)踐,多一點(diǎn)瘋狂。多一點(diǎn)點(diǎn)就能創(chuàng)造奇跡?。゛lways have a dream forget about the days when its been cloudy, but dont forget your hours in the sun.forget about the times youve been defeated, but dont forget the victories youve won.forget about the misfortunes youve encountered, but dont forget the times your luck has turned.forget about the days when youve been lonely, but dont forget the friendly smiles youve seen.forget about the plans that didnt seem to work out right, but dont forget to always have a dream.永不放棄夢(mèng)想忘掉你的失意日子,但不要忘記黃金的時(shí)光。忘掉你的一次次失敗,但不要忘記你奪取的勝利。忘掉你遭遇的不幸,但不要忘記你的時(shí)來(lái)運(yùn)轉(zhuǎn)。忘掉你的孤獨(dú)日子,但不要忘記你得到的友善的微笑。忘掉你沒有得以順利實(shí)施的計(jì)劃,但不要放棄你的夢(mèng)想。

      飯吃,我就感到無(wú)比幸福和滿足,我將不會(huì)再去考慮其它的東西!我只有一個(gè)心思:一定要講一口流利的英語(yǔ)!我就不信我做不到!在這種狀態(tài)下,你肯定成功!你肯定會(huì)擁有一切你需要的東西,你想拒絕都沒有辦法!你想庸俗都沒有選擇!成功、名譽(yù)、財(cái)富!一切都隨之而來(lái)!而那些天天在想他們自己未來(lái)需求的人,最終也只能白日做夢(mèng),越做越遠(yuǎn)!讓我們將我們的欲望集中在一個(gè)地方,那就是早日攻克英語(yǔ)!一旦成功,你的人生歷史一定會(huì)重 in my 18 years of life, there have been many things.university days are the best part of them.i can never forget the days when i stepped into my university.i was impressed by its garden-like campus, its enthusiastic students and especially its learning atmosphere.i at once fell in love with it.after the arduous military training, i get absolutely absorbed in my studies.the classes given by the teachers are excellent.they provide us with information not only from our textbooks but from many other sources as well.they easily arouse my insatiable desire to take in as much as i can.frankly speaking, at first i had some difficulty following the teachers.however, through my own efforts and thanks to my teachers guidance, i made remarkable progress.now ive benefited a lot from lectures and many other academic reports.learning is a long process;ill keep exploring in the treasure house of knowledge to enrich myself.this summer i got out of the ivory tower and entered the real world.at the beginning i was belittled by my colleagues.but they were really surprised when i translated seven english articles over 5,000 words on only one day.gradually, they began to look at me with respectful eyes.in their opinion i turned out to be a useful and trustworthy colleague.mission as college students and the hope of their motherland.譯文:享受生活、牢記使命

      在我這18年的生命中,有著許多美好的經(jīng)歷,而大學(xué)生活則是其中最難忘的一段。我永遠(yuǎn)不會(huì)忘記剛剛跨進(jìn)大學(xué)校園的那幾天:花園一樣的校園,熱情活躍的學(xué)生,特別是那里的學(xué)習(xí)氣氛,給我留下了深刻的印象。hxen恒星英語(yǔ)學(xué)習(xí)網(wǎng)

      經(jīng)過(guò)了一段艱辛的軍事訓(xùn)練后,我完全融入到了學(xué)習(xí)中。老師的講課真是棒極了。他們傳授給我們的不僅是課本上的知識(shí),還包括其他各種各樣的信息。我渴望獲得盡可能多的知識(shí),是老師激發(fā)起了我這個(gè)不能滿足的欲望。hxen恒星英語(yǔ)學(xué)習(xí)網(wǎng)

      坦率地說(shuō),一開始我還不能跟上老師的講課。但是,通過(guò)我自己的努力以及老師的指導(dǎo),我取得了巨大的進(jìn)步。我從老師的授課和其他許多學(xué)術(shù)報(bào)告中獲益匪淺,恒星英語(yǔ)學(xué)習(xí)網(wǎng)

      學(xué)習(xí)是個(gè)循序漸進(jìn)、長(zhǎng)期的過(guò)程,我會(huì)在知識(shí)的寶庫(kù)中不斷探索,豐富自我。今年暑假,我跨出象牙塔,進(jìn)入并接觸到了真正的社會(huì)。一個(gè)出版社給了我編輯和校對(duì)的兼職工作。工作初期,同事們都礁不起我。但是,當(dāng)我在一天之內(nèi)翻譯完7篇(總字?jǐn)?shù)超過(guò)5000字)的英語(yǔ)文章后,他們真的是hxen恒星英語(yǔ)學(xué)習(xí)網(wǎng)

      大吃一驚。漸漸地,他們開始用尊敬的眼光看待我。他們認(rèn)為,我變成了一個(gè)有用并值得信賴的好同事。hxen恒星英語(yǔ)學(xué)習(xí)網(wǎng) 我也同樣意識(shí)到,只有那些為別人帶來(lái)幸福的人才能真正的幸福。因而,我經(jīng)常參加有關(guān)公眾福利享業(yè)的活動(dòng)。有一次,我和同學(xué)去了一個(gè)貧痔的山區(qū)村莊。在那里,我們教那些沒錢上學(xué)的孩子。我向他們展示了一幅寬廣、文明的外部世界的畫面,但同時(shí)我也被那些孩子學(xué)習(xí)的渴望、他們的真誠(chéng)和純潔深深打動(dòng)了。在我們離開的那一天,我那不爭(zhēng)氣的眼淚禁不住流了下來(lái)。這次珍貴的經(jīng)歷讓我們這些未來(lái)的教師意識(shí)到了自己肩上的責(zé)任重大。除了學(xué)習(xí)和社會(huì)實(shí)踐,我還經(jīng)常參加娛樂活動(dòng)。我每天都鍛煉身體,希望保持健康和充滿活力。我們還在業(yè)余時(shí)間寫劇本并排練演出。

      園生活是最豐富多彩的。但是,不同的人有著不同的選擇。大多數(shù)的學(xué)生珍惜他們的美好時(shí)光,并殷切希望將來(lái)能出類拔萃。可是,的確有學(xué)生無(wú)動(dòng)于衷。他們聚在一起吃喝玩樂;他們忙于追求異性朋友;他們完全忘記了自己作為大學(xué)生的使命和祖國(guó)對(duì)他們的厚望。最后,我希望每個(gè)人都能盡最大努力成為國(guó)家的有用人才。

      第五篇:科技英語(yǔ)小抄

      第一章緒論 1,科技論文的概念:簡(jiǎn)單地說(shuō),科技論文是對(duì)創(chuàng)造性的科研成果進(jìn)行理論分析和總結(jié)的科技寫作文體。比較翔實(shí)的定義是:科 技論文是報(bào)道自然科學(xué)研究和技術(shù)開發(fā)創(chuàng)新工作成果的論說(shuō)文章,它是通過(guò)運(yùn)用概念、判斷、推理、證明或反駁等邏輯思維 手段,來(lái)分析表達(dá)自然科學(xué)理論和技術(shù)開發(fā)研究成果的。2,科技論文的特點(diǎn)和寫作要求:科技論文是創(chuàng)新性科學(xué)技術(shù)研究工作成果的科學(xué)論述,是某些理論性、實(shí)驗(yàn)性或觀測(cè)性新知識(shí) 的科學(xué)記錄,是某些已知原理應(yīng)用于實(shí)際中取得新進(jìn)展、新成果的科學(xué)總結(jié)??萍颊撐耐话愕目萍嘉恼掠泄餐帲哂?準(zhǔn)確、鮮明、生動(dòng)的特點(diǎn),但作為科技論文,它又有自身的特殊屬性。3,一篇科技論文必須同時(shí)具有下述特點(diǎn),并同時(shí)滿足下述寫作要求:1)、科學(xué)性:真實(shí)性,準(zhǔn)確性,可重復(fù)性,邏輯性 2)、創(chuàng)新性或獨(dú)創(chuàng)性3)、理論性或?qū)嵱眯?)、條理性和規(guī)范性 4,《科學(xué)》遵循的是學(xué)術(shù)期刊的發(fā)表慣例,先讓三名同行審稿才發(fā)表。同行審稿時(shí)主要是看論文本身提供的證據(jù)是否充足,成果是否重大,并不會(huì)輕易懷疑論文的作者造假。除非假造得很拙劣,否則也不太可能在審稿時(shí)被發(fā)現(xiàn)有假 5,現(xiàn)在的通行做法是先發(fā)表論文再說(shuō)。是否能被獨(dú)立地重復(fù)出來(lái),永遠(yuǎn)是一個(gè)科學(xué)成果能否成立的必要條件。6,科技論文就其發(fā)揮的作用來(lái)看可分為三類:

      二、技術(shù)性論文;

      三、學(xué)位論文。7,學(xué)位論文是指學(xué)位申請(qǐng)者提交的論文。這類論文依學(xué)位的高低又分為以下3 種:學(xué)士論文、碩士論文和博士論文。8,按研究的方式和論述的內(nèi)容可對(duì)科技論文分六類。

      1、實(shí)(試)驗(yàn)研究報(bào)告;

      2、理論推導(dǎo);

      3、理論分析;

      4、設(shè)計(jì)計(jì)算;

      5、專題論述;

      6、綜合論述。9,撰寫科技論文的要素:興趣愛好,主動(dòng)與被動(dòng)的關(guān)系;經(jīng)驗(yàn)積累,切記急功近利;理論功底,學(xué)習(xí)、學(xué)習(xí)、再學(xué)習(xí);寫作 技巧,臨摹、請(qǐng)教、發(fā)揮 10,科技論文作者應(yīng)有的基本素養(yǎng):1 文獻(xiàn)資料的查閱技能,2 信息積累,3 通曉科技論文寫作的理論和格式,4 有一定的語(yǔ)法和 文字修辭上的素養(yǎng),5 了解期刊編輯知識(shí),6 善于對(duì)讀者對(duì)象分析研究 11,科技論文作者專業(yè)知識(shí)包括
