摘要:

  大家知道,托福閱讀備考是個(gè)長期的過程,在前期詞匯的積累過程中,令各位寶寶頭疼的不僅僅是像exuberance,centrifugal這樣的長單詞,一些小詞也同樣困擾著我們,比如as這個(gè)詞,它的無所不在及意思繁多就給我們理解句子帶來很多麻煩。

  今天我們就來簡單的總結(jié)一下這個(gè)小連詞在托福閱讀中的作用,注意啊是托福閱讀,如果你想了解它的全部意思,請參考牛津詞典,朗文詞典,韋氏英語詞典...

  01一個(gè)數(shù)字標(biāo)題

  as做連詞(連接句子)最主要的有兩個(gè)用法:

  1) 做時(shí)間狀語從句,表示隨著.../當(dāng)...時(shí)候,相當(dāng)于when

  eg. As the new markets created fortunes for the few, the factory systemlowered the wages of workers by dividing labor into smaller, lessskilled tasks. (摘自O(shè)GArtisansand Industrialization)

  隨著新市場為少數(shù)人創(chuàng)造了財(cái)富,工廠體系通過將勞動力分成更小、技能更低的任務(wù),降低了工人的工資。

  Asoil becomes increasingly difficult to find, the search for it isextended into more-hostile environments. (摘自tpo4PetroleumResources)

  隨著石油越來越難找到,對它的搜尋也延伸到了更惡劣的環(huán)境中。

  2)做原因狀語從句,表示由于,因?yàn)?,相?dāng)于because

  eg. Until the 1970s, it was widely assumed that Chaco had been a forestedoasis that attracted farmers who initially flourished but eventuallyfell victim to their own success and exuberance, as they denuded the canyon of trees and vegetation to build large greathouses. (摘自真題ChacoPhenomenon)

  直到20世紀(jì)70年代,人們普遍認(rèn)為Chaco是一片森林覆蓋的綠洲吸引了不少農(nóng)民,他們起初很繁榮,但最終卻淪為自己的成功和繁榮的犧牲品,因?yàn)樗麄兛撤チ藣{谷中的樹木和植被來建造了巨大的房屋

  Certainly,rational appeals in advertising aimed at children are limited,asmost advertisements use emotional and indirect appeals topsychological states or associations.(摘自tpo14Childrenand Advertising)

  當(dāng)然,在針對兒童的廣告中,理性訴求是有限的,因?yàn)榇蠖鄶?shù)廣告都是對心理狀態(tài)或聯(lián)想的情感訴求和間接訴求。

  02一個(gè)數(shù)字標(biāo)題

  as做介詞的時(shí)候,后邊跟名詞或v-ing的形式,表示“作為”

  eg.Of158 stencils in the French cave of Gargas, 136 have been identifiedasleft,and only 22 asright;right-handedness was therefore heavily predominant.(摘自tpo12WhichHand Did They Use)

  在法國加加斯洞穴的158個(gè)模板中,有136個(gè)被認(rèn)為是左邊的,只有22個(gè)是右邊的;因此,慣用右手的人占絕大多數(shù)。

  Sociologistsview primary groups asbridgesbetween individuals and the larger society because they transmit,mediate, and interpret a society's cultural patterns and provide thesense of oneness so critical for social solidarity.(摘自tpo13Typesof Social Groups)

  社會學(xué)家認(rèn)為,主要群體是作為個(gè)體與大社會之間的橋梁,因?yàn)樗鼈儌鞑ァ⒄{(diào)解和解釋社會的文化模式,并提供對社會團(tuán)結(jié)至關(guān)重要的統(tǒng)一性。

  03一個(gè)數(shù)字標(biāo)題

  關(guān)系代詞這個(gè)名字只有在定語從句中才有。當(dāng)as出現(xiàn)在定語從句中時(shí),往往做的是非限制性從句,指代前邊一句話或者一件事,表示“正如,就像”

  eg.whydid they not discover the geometric perspective as European artists did in the Renaissance?(摘自tpo11AncientEgyptian Sculpture)

  為什么他們不像歐洲文藝復(fù)興時(shí)期的藝術(shù)家那樣發(fā)現(xiàn)幾何角度呢?

  Filtering seawater for its particulate nutritional content can be anenergetically demanding method of feeding, particularly when thecurrent of water to be filtered has to be generated by the organismitself, as is the case for all planktonic animals. (摘自tpo45 FeedingStrategies in the Ocean)

  過濾海水的微粒營養(yǎng)成分可能是一種需要能量的喂養(yǎng)方法,特別是當(dāng)需要過濾的水流必須由生物體本身產(chǎn)生時(shí),就像所有浮游動物一樣。

  當(dāng)然,as的具體意思還有很多,這里總結(jié)的只是在托福閱讀中常見的三種形式:連詞,介詞和關(guān)系代詞。還有一個(gè)小小的技巧,就是平時(shí)記這樣的小詞多記它的語境,比干背它的用法要容易很多,如果覺得有用就趕緊轉(zhuǎn)發(fā)給你的小伙伴吧!歡迎關(guān)注( 托福君TOEFL)。
