猜詞義，是指在閱讀過程中根據(jù)對語篇提供的信息、行文邏輯、背景知識及語言結(jié)構(gòu)等的綜合理解去猜測或推斷某個生詞、難詞、關(guān)鍵詞的詞義。英語詞語的意義非常豐富，語境不同，詞義也就不同。所以解決此類題目要掌握一定的猜詞策略。
　　-根據(jù)上下文語境進行猜測

　　一個單詞或詞組的確切含義是和它所處的上下文語境分不開的，所以我們可借助上下文語境對需要猜測的詞或短語進行合乎邏輯的推測。

　　例1.(2002年全國卷，B篇)“Organic produce is always better，”Gold said.“The food is free of pesticides(農(nóng)藥)，and you are generally supporting family farms instead of large farms.And more often than not it is locally(本地)grown and seasonal，so it is more tasty.”Gold is one of a growing number of shoppers buying into the organic trend，and supermarkets across Britain are counting on more like him as they grow their organic food business.

　　62.What is the meaning of “the organic trend”as the words are used in the text？

　　A.growing interest in organic food

　　B.better quality of organic food

　　C.rising market for organic food

　　D.higher prices of organic food

　　分析：由最后一句話可知，越來越多的人購買organic food，說明人們越來越看好organic food。致使全英國的超市增加了organic food business，以期望有更多像Gold這樣的人前來購買。因此答案為A。

　　-根據(jù)同義、反義關(guān)系進行猜測

　　在文章中，當詞或短語之間有并列連詞and或or時，其前后的兩項內(nèi)容在含義上是接近的或遞進的，由此我們可以確定同等關(guān)系中的某個生詞所屬的義域。如happyandgay即使你不知道gay的意思，也能猜出其意為“快樂的”。

　　例2.(2003年全國卷，C篇)Fermat's Last Theorem(定理).First put forward by the French mathematician Pierrede Fermat in the seventeenth century，the theorem had baffled and beaten the finest mathematical minds，including a French woman scientist who made a major advance in working out the problem，and who had to dress like a man in order to be able to study at the Ecole Polytechnique.

　　65.Which of the following best explains the meaning of the word “baffle” as it is used in the text？

　　A.To encourage people to raise questions.

　　B.To cause difficulty in understanding.

　　C.To provide a person with an explanation.

　　D.To limit people's imagination.

　　分析：由句中不難看出Fermat的定理使得最具數(shù)學頭腦的科學家絞盡腦汁(beat)，并且在句中beaten和baffled由and連接，處于同等并列關(guān)系，據(jù)此推斷出baffle為“使困惑、難倒、難以理解”的意思。故答案為B。
