GCT英語閱讀答題中，我們常常會遇到一些不認識的字或詞，那么面對這種情況，我們該如何應對呢?中國教育在線為大家總結(jié)了幾種方法，希望能對大家的復習備考有所幫助。

　　1 根據(jù)語境推斷括號中詞語的意思

　　1. The woman and the children were skilful in boats too, but there were usually several of them in a large boat called (umiak)。

　　2. The doctor said that if a person ate even one leaf of the (hemlock) plant, he would die, because the plant is a deadly poison.

　　3. Although dogs and cats often have large families, rabbits are famous for the size of their (litters)， which sometimes number more than twelve bunnies at one time.

　　4. Mark became (hysterical) when his basketball team won, and he did not calm down for several days.

　　5. With mud from head to toe, flowers still clutched in his hand, john looked so (ludicrous) that we couldn?t help laughing.

　　6. A bee collects (nectar) not in its own stomach but in a kind of shopping bag called the honey sac similar to the one ants have.

　　7. Several generations ago, the world seemed to run in an or-derly way. now, however, everything is in a state of (tur-moil)。

　　8. After the first time someone tried to rob him, the banker be-came (flustered) easily, and in his confusion he would make many careless errors.

　　9. Jane was (intrigued) by the behavior of animals; she could sit for hours observing a bird making a nest or an ant carrying a leaf.

　　10. Some chimps are very independent and appear to be the superior members of a group; others seem to be ruled by the leaders and are quite (submissive)。

　　通過上串下聯(lián)，我們不難確定上述各句中斜體字的含義如下：

　　1. umiak n. 一種大船

　　2. hemlock n. 一種有毒植物(毒芹)

　　3. litter n.一窩 bunnies小兔子

　　4. hysterical a.歇斯底里，異常興奮

　　5. ludicrous a滑稽可笑的

　　6. nectar n.花蜜 honey sac蜜胃

　　7. tur-moil n.混亂

　　8. flustered a.慌亂的

　　9. intrigued a.感興趣

　　10.submissive a.順從的

　　2. 利用構(gòu)詞法確定詞義

　　通過觀察構(gòu)詞部分，分析辨認單詞，是提高閱讀速度的技巧之一。一方面，讀者不必停下來查詞典，繼續(xù)往下讀;另一方面，也大大增加了讀者的詞匯量，讀者通過已知詞綴(包括前綴和后綴)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(意為chemical)和therapy (意為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的詞義可猜測為“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)+后綴 -ible(能……的)構(gòu)成。幾部分組合在一起，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.

　　其中的dispassioned為超綱詞，我們可根據(jù)構(gòu)詞法dis + passion + ed知其大概意思：除掉激情的，也即是“冷靜的”。

　　3. 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為“日食”。

　　例4：ventilation, as we know, is a system or means of provid-ing fresh air. it plays a very important part in the field of engineering.

　　通過后面的解釋我們知道ventilation為“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，通過后面的同位語解釋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。

　　4. 根據(jù)同義、反義關(guān)系確定詞義

　　閱讀中，特別是要注意表示反意的信號詞：in contrast, on the other hand, rather than, however, yet, although, while, unlike, but, whereas, as opposed to等，利用這些同義、反義關(guān)系，可以幫助我們確定詞義。

　　例1：my sister mane is an optimist, while her boyfriend is one who is always gloomy and expects the worst to happen.

　　從while的轉(zhuǎn)折關(guān)系可知optimist意思是“one who expects the best?‘， 即”樂觀的“。

　　例2：mother was tall, fat, and middle aged. The principal of the school was an older woman, almost as plump as mother, and much shorter.

　　根據(jù)mother was tall, fat 以及后面as plump as的同義關(guān)系，我們知道plump為”豐滿的“之意。

　　例3：sally liked to concoct all sorts of stories, but her mother always knew when she was lying.

　　concoct一詞大家不熟悉，根據(jù)but的轉(zhuǎn)折關(guān)系我們知道在此句中與was lying的含義大體相同，由此可知concoct的大概意思是”編造謊話“。

　　例4：a gorilla always makes me think of the word aloof—not friendly, of distance from others.

　　假定我們不認識aloof一詞，破折號后的反義關(guān)系：”不友好，冷漠“ 就解釋了aloof一詞的含義。

　　5. 利用邏輯推理和常識確定詞義

　　有時候，邏輯推理和自身的生活經(jīng)驗及普通常識能幫助我們確定詞義。

　　例1：fishes live in water and have fins which help them to swim. most fishes have slimy skins covered with scales, but in fishes such as eels the scales are very small and can hardly be seen.

　　憑常識我們不難猜出fins, slimy和scales的確切意思分別是”鰭“、”滑溜的“和”鱗“，對于eels一詞，我們只需知道是fish的一種(鱔魚類)就行了。

　　例2：not wanting to disturb the sleeping kitten, i gingerly lifted her from the box and put her on a blanket near the heater.

　　根據(jù)前半句的not wanting to disturb(不愿打擾)，我們便可大致推測出gingerly一詞的含義：”小心翼翼地“。

　　例3：a mercury thermometer is made of a glass tube with a bulb at one end.

　　憑常識我們知道溫度計下面的bulb是”水銀球“。

　　例4：most troubles can be avoided, but death and taxes are in-evitable.

　　憑常識我們知道死亡和稅收是不可避免的(in-evitable)事情。
