一、利用定義式線索進(jìn)行猜測
定義是作者為了更好地表達(dá)思想,在文章中對(duì)一些重要的概念、難懂的術(shù)語或 詞匯等所作的解釋。這些解釋提供的信息具有明確的針對(duì)性,利用它們猜測詞義比較容易。例如:Kinetic energy is the energy of moving particles. Kinetic enegry 可能是生詞,由定義可知,表語是說明主語性質(zhì)內(nèi)容的。所以kinetic energy就是“運(yùn)動(dòng)粒子的能量”。再如Typhoons are cyclones,storms with strong winds rotating around a low-pressure center.如果cyclones是生詞,推斷該詞義的線索就是其后面的解釋“繞低氣壓中心形成的暴風(fēng)雨”由此我們可知cyclones的意思是“繞低氣壓中心形成的暴風(fēng)雨”。在這種解釋中定義句的謂語動(dòng)詞多為:be, mean, deal with, be considered, to be, refer to, be called, be known as, define, represent, signify, constitute等。
二、根據(jù)進(jìn)一步闡述猜測詞義
雖然進(jìn)一步闡述不如定義那樣嚴(yán)謹(jǐn)、詳細(xì),但是提供的信息足以使我們猜出生詞的詞義。復(fù)述部分可以是適當(dāng)?shù)脑~,短語或者句子。例如Experts in kinesics, in their study of body motion as related to speech ,hope to discover new methods of communications. 逗號(hào)中短語的意思是“對(duì)肢體語言進(jìn)行研究的學(xué)科”。短語與前面生詞kinesics是同位關(guān)系,因此我們不難猜出kinesics指“肢體語言學(xué)”。在這種復(fù)述當(dāng)中,構(gòu)成同位關(guān)系的兩部分之間多用逗號(hào)連接,有時(shí)也使用破折號(hào),冒號(hào),分號(hào),引號(hào),和括號(hào)等。另外同位語前還常有or, similarly, that is to say, in other words, namely, or other, 等副詞或短語出現(xiàn)。另外一種會(huì)以定語從句的形式出現(xiàn)如從句Obesity, which is a medical disorder that affects approximately 20-30% of the population of the United States of America. It is an excessive accumulation of body fat that results from the storage of excess food energy calories in the body's fat cells. 根據(jù)生詞obesity后面的非限制性定語從句which is a medical disorder that affects approximately 20-30% of the population of the United States of America. It is an excessive accumulation of body fat that results from the storage of excess food energy calories in the body's fat cells. 我們可以推斷出 obesity的含義,即“過度肥胖”。
三、根據(jù)舉例猜測詞義
恰當(dāng)?shù)呐e例能夠提供猜測生詞的重要線索,例如The consequences of epochal events such as wars and great scientific discoveries are not confined to a small geographical area as they were in the past. 句中“戰(zhàn)爭”和“重大科學(xué)發(fā)現(xiàn)”是生詞的實(shí)例,通過它們我們可以猜出epochal的 大致詞義“重要的”。
四、根據(jù)上下文的語境關(guān)聯(lián)猜測詞義
例如Computers have been used for most kinds of crime, including fraud theft, larceny, embezzlement, burglary, sabotage, murder and forgery, since the first cases were reported in 1985. 這句話中有許多生詞出現(xiàn),但通過上文的crime和murder一詞,我們可以知道這些下劃線詞都是與犯罪有關(guān)的詞。在考試中,就不必費(fèi)心去考慮它們的具體意思,知道大概類別即可。再如Goran Ivanisevic fears only one service in tennis -- Michael Stichs. His toss is always the same: the straight one or the topspin. Sampras has a good serve and Becker too, but Stichs is the toughest to read.在此例中,大多數(shù)詞用于網(wǎng)球運(yùn)動(dòng)中的一些專門詞匯,我們可以不必理會(huì),而主要關(guān)注認(rèn)識(shí)的那些詞。這樣能夠大概理解此句講的是網(wǎng)球選手Goran害怕某種service, 通過上下文大致可得知這是指網(wǎng)球運(yùn)動(dòng)中的一個(gè)動(dòng)作(比如發(fā)球、扣球等)。其實(shí),service就是“發(fā)球”的意思。從形容詞straight可知Stichs發(fā)球的特點(diǎn),而且他是最難預(yù)測的一個(gè)。這樣一來就可以很好地把握文章內(nèi)容了。
五、根據(jù)對(duì)比關(guān)系猜測詞義
在一個(gè)句子或段落中,有對(duì)兩個(gè)事物或現(xiàn)象進(jìn)行對(duì)比性的描述,我們可以根據(jù)生詞或難詞的反義詞猜測其詞義。 例如:Unlike her gregarious sister, Jane is a shy, unsociable person who does not like to go to parties or to make new friends. Gregarious, 對(duì)許多人來說可能是個(gè)生詞,但是句中單詞unlike可以提示我們Gregarious和后面的詞unsociable person是對(duì)比關(guān)系。分析出這種關(guān)系后,我們便能猜出意為Gregarious是“愛交際的”。
六、根據(jù)常識(shí)性線索猜測題義
這是指根據(jù)篇章(句子或段落)以外的其他知識(shí)來猜測詞義。有時(shí)僅靠分析篇章內(nèi)在邏輯關(guān)系無法猜出詞義。這時(shí),就需要運(yùn)用生活經(jīng)驗(yàn)和普通常識(shí)確定詞義。例如:The cat came quickly through the grass towards the birds ,when it was just a few from the feet from the victim, it gather its legs under itself and pounced.如果pounce 是生詞。推測該詞我們可以憑借我們的常識(shí),我們知道當(dāng)貓看到鳥時(shí),通常它會(huì)先把爪子收起來,然后再突然向小鳥發(fā)起進(jìn)攻。由此可以推斷pounce一詞的意思是“突然攻擊”。再如It's really cold out tonight. My hands are practically numb. 根據(jù)生活經(jīng)驗(yàn),天氣寒冷時(shí),手肯定是numb “凍僵的,凍得麻木的”。
七、利用構(gòu)詞法猜測詞義
此法包括利用前、后綴及合成詞猜測詞義。
7.1前、后綴猜測詞義
英語中的前綴、后綴構(gòu)詞頗多,且特定的"綴"往往表示特定的含義,把握住這一點(diǎn),可起到"以不變應(yīng)萬變"的效果。例如He had been overworking and fell ill at last. overwork是由前綴over-加動(dòng)詞構(gòu)成,over有"超過,過于"之意,overwork意思是"工作過多,勞累過度"。再如,overburden負(fù)擔(dān)過重,overcharge要價(jià)過高,overdo做得過分。英語中常用的前綴還有:mis-錯(cuò),誤:misfortune不幸;mislead誤導(dǎo);mismanage處理不當(dāng)mid-中央:midnight半夜;midway半路under-低于:underdone半生不熟的;underestimate低估;anti-反對(duì):antibody抗體;anticyclone反氣旋;antifreeze防凍劑。還有一些后綴派生詞:例如1)You must stop dreaming and face reality.(-ty為名詞的標(biāo)志); 2)The country is trying to popularize education. (-ize為及物動(dòng)詞的標(biāo)志,再如realize, modernize)。
7.2利用合成詞猜測詞義
Family members take turns choosing a special activity for the evening, and everyone partakes in for fun. 根據(jù)短語構(gòu)成及上下文意思看,此處partakes in相當(dāng)于takes part in。再如break out-outbreak(名詞"爆發(fā)"),set out-outset(名詞"起始"),come in-income(名詞“收入”)。
猜測是雅思閱讀中一項(xiàng)很重要的技巧。本文介紹了幾種猜測詞義的方法,相信通過積累詞匯,大量練習(xí)對(duì)理解文章意思會(huì)有所幫助。英語學(xué)習(xí)應(yīng)該日積月累,并時(shí)刻做有心人,發(fā)現(xiàn)規(guī)律,尋找技巧,這樣才能更有效的提高英語水平。
