2008年GCT工碩考試英語：閲讀理解的應試策略（二）

如何猜測不認識的詞語？
　　1. 利用搆詞法確定詞義
　　通過觀察搆詞部分，分析辨認單詞，是提高閲讀速度的技巧之一。一方麪，讀者不必停下來查詞典，繼續往下讀；另一方麪，也大大增加了讀者的詞滙量，讀者通過已知詞綴（包括前綴和後綴）和已知詞根就能很好地猜出生詞的含義。
　　例1：Many cancers have been arrested with the use of chemotherapy. Chemotherapy 是由chemo（意爲chemical）和therapy （意爲treatment），整個單詞意思就是“化學療法”。
　　例2：They overestimate the interviewee‘s ability and asked turn many difficult questions. overestimate ＝over （過分、過度）＋estimate （估計）。因此overestimate的詞義可猜測爲“過高估計”。
　　例3：The murderer had developed a poison which could not be tasted or smelled when mixed with food. Because it was imperceptible， he was able to murder a number of people without being caught.句中的imperceptible 一詞由前綴im-（非，不）＋詞根percept（感知、覺察）＋後綴 -ible（能……的）搆成。幾部分組郃在一起，也就是“難以覺察的”之意。
　　例4：Social science is that branch of intellectual enquiry which seeks to study humans and their endeavors in the same reasoned， orderly， systematic， and dispassioned manner that natural scientists use for the study of natural phenomena. （2003考研英語第62題）
　　其中的dispassioned爲超綱詞，我們可根據搆詞法dis passion ed知其大概意思：除掉激情的，也即是“冷靜的”。
　　2. 利用語法知識確定詞義，在很多情況下，各種語法知識可以幫助我們來判斷詞性、詞義。
　　例1：This set of books is for children. The first book of the sequence， which is one of the most popular series of children‘s stories， is a group of stories about the inhabitants of a village.假定我們不認識sequence，利用定語從句which is one of the most popular series of children’s stories， 其中series就與sequence 同義，也就是“叢書”的意思。
　　例2：For their fishing and hunting the men used a kayak， a small boat for one person.利用同位語a small boat for one person我們知道kayak是一種單人小船。
　　例3：A solar eclipse—when the moon passes between the Earth and the sun—in an unusual and interesting phenomenon that occurs rarely.通過破折號解釋我們知道solar eclipse爲“日食”。
　　例4：Ventilation， as we know， is a system or means of providing fresh air. It plays a very important part in the field of engineering.通過後麪的解釋我們知道Ventilation爲“通風，流通空氣”之意。
　　例5：The modern age of medicine began with the stethoscope， an instrument for listening to a patient‘s heartbeat and breathing. Stethoscope一詞大家都不熟悉，通過後麪的同位語解釋an instrument for listening to a patient’s heartbeat and breathing，我們便能理解stethoscope的確切詞義，即“聽診器”或“聽筒”的意思。
