   阅读理解除了要求正确理解事实细节的能力外,还经常需要考生根据一定上下文对某些词汇的意义 所读材料理解文章隐含的意义和深层次的含义、归纳文章主题思想、通过概括得出结论、综合判断作者态度等,这就要求考生具备相应的阅读理解微技能,与四级考试密切相关的一些微技能包括词汇的理解、预测、判断、归纳和推理。


  词汇的理解
  对于阅读中碰到的生僻词,我们首先要学会识别哪些情况下即使不了解词义也不影响对短文的理解;其次是转变对生僻词义认识上的态度,即在许多情况下不必了解该词的确切意义,尤其没有必要了解它在英汉辞典中的中文释义,而只需对该词词义的大概而笼统的理解就行。实践中,在确定了短文中哪些生僻词的词义有必要作一大概了解后,我们可以从以下两个角度来猜度词义:
  (1) 构词知识
  即利用单词的构词要素词根,前后缀来识记单词。
  词根是一个单词的根本部分,代表词的基本意义;前缀是加在词根或单词前面的部分,通常也有一定含义;后缀是加在词根或单词后面的部分,通常在增加词义的同时还改变词性。通过词根词缀构词的方式有多种,现简单归纳如下:
  ①前缀+词根:inter(中间)+vene→intervene(介入)
  ②词根+后缀:circl(圆)+let(小)→circlet(小环)
  ③词根+词根:tele(远)+scope(镜)→telescope(望远镜)
  ④前缀+词根+后缀:in(不)+aud(听)+ible(可)→inaudible(听不见)
  ⑤双前缀+词根:re(再)+dis(取下)+cover(盖)→rediscover(再发现)
  ⑥词根+双后缀:care(用心)+less(不)+ly(地)→carelessly(不小心地)
  ⑦前缀+双词根:tri(三)+gono(角)+metry(测量)→trigonometry(三角几何)
  ⑧双词根+后缀:biblio(书)+phil(爱)+ist(人)→bibliophilist(书籍爱好者)
  ⑨双前缀+词根+后缀:ir(不)+re(反对)+sist(站)+ible→irresistible(不可抵抗的)
  前缀+词根+双后缀:se(离)+greg(群)+ation+ist→segregationist(种族隔离主义者)
  双前缀+词根+双后缀:un(不)+pre(先)+ced(走)+ent+ed→unprecedented(史无前例的)
  (2) 上下文线索
  利用上下文线索猜测词义的方法很多,但其核心是寻找与该生僻词相关的上下文意义线索,这些线索主要可归纳为以下几种:
  ①同义定义为了便于读者理解作者本义,作者有时会对文中的生僻词或专业性较强的词直接给出定义。在下定义时,作者常使用一些信号词,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.
  或标点符号,如——,()等,例:
  Multiplexing ——transmitting independent signals at the same time in the same channel——increases the efficiency of radio channels.
  有时,作者用同位语形式或连词or给出定义,例:
  Nerve cells evidently first appeared in coelenterates, “hollowgutted” organisms like hydra 1 and the sea anemone 2.
  Intelligent behavior remained impossible until the appearance of relatively 3 big, complex types of brain——the types we find among the vertebrates, or backboned animals.
  ②近义复述同一短文中上下毗邻的句子通常有互释作用,我们可以从上下文的复述中获取与某一单词相关的信息来猜度词义。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 4 his future.
  ③反义对照在表示对照的上下文中,常包含有意义相反的词语或概念,这些意义相反的概念可以互为线索,帮助我们猜度词义。常有以下一些信号词:although,but,however, though,whereas,while,yet,on the contrary,on the other hand等。

n.水螅;难于根除的祸患
  • Let's knock down those hydras and drive them to the sea!让我们铲除祸根,把他们赶到大海去!
  • We may be facing a hydra that defies any easy solution.我们也许正面临一个无法轻易解决的难题。
n.海葵
  • Do you want this anemone to sting you?你想让这个海葵刺疼你吗?
  • The bodies of the hydra and sea anemone can produce buds.水螅和海葵的身体能产生芽。
adv.比较...地,相对地
  • The rabbit is a relatively recent introduction in Australia.兔子是相对较新引入澳大利亚的物种。
  • The operation was relatively painless.手术相对来说不痛。
vt.危及,损害
  • Overworking can jeopardize your health.工作过量可能会危及你的健康。
  • If you are rude to the boss it may jeopardize your chances of success.如果你对上司无礼,那就可能断送你成功的机会。
