英語四級閱讀沖刺:高分技能

字號:

閱讀理解除了要求正確理解事實細(xì)節(jié)的能力外,還經(jīng)常需要考生根據(jù)一定上下文對某些詞匯的意義進(jìn)行推斷、根據(jù)所讀材料理解文章隱含的意義和深層次的含義、歸 納文章主題思想、通過概括得出結(jié)論、綜合判斷作者態(tài)度等,這就要求考生具備相應(yīng)的閱讀理解微技能,與四級考試密切相關(guān)的一些微技能包括詞匯的理解、預(yù)測、 判斷、歸納和推理。
    詞匯的理解
    對 于閱讀中碰到的生僻詞,我們首先要學(xué)會識別哪些情況下即使不了解詞義也不影響對短文的理解;其次是轉(zhuǎn)變對生僻詞義認(rèn)識上的態(tài)度,即在許多情況下不必了解該 詞的確切意義,尤其沒有必要了解它在英漢辭典中的中文釋義,而只需對該詞詞義的大概而籠統(tǒng)的理解就行。實踐中,在確定了短文中哪些生僻詞的詞義有必要作一 大概了解后,我們可以從以下兩個角度來猜度詞義:
    (1) 構(gòu)詞知識
    即利用單詞的構(gòu)詞要素詞根,前后綴來識記單詞。
    詞根是一個單詞的根本部分,代表詞的基本意義;前綴是加在詞根或單詞前面的部分,通常也有一定含義;后綴是加在詞根或單詞后面的部分,通常在增加詞義的同時還改變詞性。通過詞根詞綴構(gòu)詞的方式有多種,現(xiàn)簡單歸納如下:
    ①前綴+詞根:inter(中間)+vene→intervene(介入)
    ②詞根+后綴:circl(圓)+let(小)→circlet(小環(huán))
    ③詞根+詞根:tele(遠(yuǎn))+scope(鏡)→telescope(望遠(yuǎn)鏡)
    ④前綴+詞根+后綴:in(不)+aud(聽)+ible(可)→inaudible(聽不見)
    ⑤雙前綴+詞根:re(再)+dis(取下)+cover(蓋)→rediscover(再發(fā)現(xiàn))
    ⑥詞根+雙后綴:care(用心)+less(不)+ly(地)→carelessly(不小心地)
    ⑦前綴+雙詞根:tri(三)+gono(角)+metry(測量)→trigonometry(三角幾何)
    ⑧雙詞根+后綴:biblio(書)+phil(愛)+ist(人)→bibliophilist(書籍愛好者)
    ⑨雙前綴+詞根+后綴:ir(不)+re(反對)+sist(站)+ible→irresistible(不可抵抗的)
    前綴+詞根+雙后綴:se(離)+greg(群)+ation+ist→segregationist(種族隔離主義者)
    雙前綴+詞根+雙后綴:un(不)+pre(先)+ced(走)+ent+ed→unprecedented(史無前例的)
    (2) 上下文線索
    利用上下文線索猜測詞義的方法很多,但其核心是尋找與該生僻詞相關(guān)的上下文意義線索,這些線索主要可歸納為以下幾種:
    ① 同義定義為了便于讀者理解作者本義,作者有時會對文中的生僻詞或?qū)I(yè)性較強(qiáng)的詞直接給出定義。在下定義時,作者常使用一些信號詞,如:is/are (called),means,can be defined as,refer to,is/are known as,signify等,例:
    Food fallacies refer to beliefs about food that are not true.
    或標(biāo)點符號,如——,()等,例:
    Multiplexing ——transmitting independent signals at the same time in the same channel——increases the efficiency of radio channels.
    有時,作者用同位語形式或連詞or給出定義,例:
    Nerve cells evidently first appeared in coelenterates, “hollowgutted” organisms like hydra and the sea anemone.
    Intelligent behavior remained impossible until the appearance of relatively big,complex types of brain——the types we find among the vertebrates,or backboned animals.
    ②近義復(fù)述同一短文中上下毗鄰的句子通常有互釋作用,我們可以從上下文的復(fù)述中獲取與某一單詞相關(guān)的信息來猜度詞義。例:
    Mr. and Mrs. Firth had a long courtship. They dated for nine years before they got married.
    Although he often had the opportunity,Mr. Tritt never stole money from a customer. This would have endangered his position at the bank,and he did not want to jeopardize his future.
    ③反義對照在表示對照的上下文中,常包含有意義相反 的詞語或概念,這些意義相反的概念可以互為線索,幫助我們猜度詞義。常有以下一些信號詞:although,but,however,though, whereas,while,yet,on the contrary,on the other hand等。
    例:Chimpanzees(猩猩) in the wild use simple objects as tools,but in laboratory situations they can use more sophisticated items.
    Most dentists-offices are drab places,while Emilio’s new office is a bright,cheerful place.
    ④搭配集合利用詞與詞的搭配或該詞所出現(xiàn)的語境,我們也能推知詞義的大概輪廓。例:
    People gathered to look. Three fine streams of hot water sprouted from holes in the jacket(套,殼) of the radiator.
    A man is watering his lawn just as an attractive,well dressed girl walked by. As he ogles her,he accidentally turns the hose on his ugly,dowdy wife.
    ⑤比較舉例上下文中的比較和舉例,能揭示比較物或列舉物之間的共性,我們可根據(jù)這些共性來推知有關(guān)詞語的意思。例:
    The consequences of epochal events such as wars and great scientific discoveries are not confined to a small geographical area.
    Doctors believe that smoking cigarettes is detrimental to your health. They also regard drinking as harmful.
    ⑥因果時間因與果、時間的先與后都是事物發(fā)展變化過程中的必然關(guān)系,在利用上下文推測詞義時,這些關(guān)系也至關(guān)重要。例:
    Robert is considered peremptory administrator because he makes decisions without seeking the opinions of others.
    When Mark was in pedantic mood,he assumed the manner of a famous professor and gave long lectures on boring, insignificant topics.
    ⑦常識包括我們的生活經(jīng)歷、經(jīng)驗常識以及自己專業(yè)方面的知識,在閱讀到與自己專業(yè)相近的文章時,我們都會感到相對容易,這正是我們的專業(yè)知識在幫我們理解。例:
    An apple falls up because of gravity.
    An atomic clock is so precise that it can be used to check the accuracy of predictions based on Einstein’s relativity theories
