例20.I had first known she was wrong, that her anxiety had clouded her judgment. cloud本为名词。分析语境逻辑可知，忧虑会影响一个人的判断，因此该句clouded应译为使难以……。

四、是根据生活常识

运用自身的生活经验及生活常识，根据上下文能读懂的部分，可以正确猜出词义。

例19.The other teams, disappointed, were on the bus heading home. （2004年山东卷）
head本为名词，表头。由the bus和home的语境逻辑可以推断，该句head为动词，表方向，结合全句可译为“开往、驶向”。

例18. We live in a technological society where most goods are mass-produced by unskilled labor. Because of this, most people that craft (手艺) no longer exists.

根据合成词中的mass （大量的）和produce （生产），我们可以推测 mass-produce的意思是：“大批量生产；规模生产”的意思。

4）猜测词性变换新词含义

例17.Good tool design is important in the prevention of overuse injuries. Well ? designed tools and equipment will require less force to operate them and prevent awkward（别扭的）hand positions.（2005年北京卷）

Well-designed 或许是个生词，但我们分析该词的结构后，就能推测出其含义。它由well （好，优秀）和design （设计）两部分组成，合在一起便是“设计精巧的”意思。

例16. It's a quiet, comfortable hotel overlooking (俯瞰) the bay in an uncommercialized Cornish fishing village on England's most southerly point．

后缀 -ise/ize意思是“使成为…；使…化”，结合词根commercial（商业的），不难猜出 uncommercialized 的意思是：“未被商业化的”。

3）根据复合词的各部分猜测词义

例15.Do you have any strong opinion on co-educational or single-sex schools?

根据词根educational （教育的），结合前缀co-（共同，一起），我们便可以猜出co-educational的意思是：“男女同校教育的”意思。

2）根据后缀猜测词义

例14.Most women in China ---educated and illiterated, urban and rural, the young and old-----work to earn an income in addition to maintaining their roles as housewives and mothers.

[分析]后面的urban and rural, the young and old之间都有反义关系，运用这个关系可以推断illiterated为“未接受过教育的，即文盲”

在猜测词义过程中，我们还可以依靠构词法方面的知识，从生词本身猜测词义。

1）根据前缀猜测词义

例13.The house stood at the end of a quiet neat street. The little dwelling,however,looked neglected and cheerless.

[分析]运用与The house近义关系可以推断dwelling与住所有关

例12.The game Americans call soccer is known around the world as football.

[分析]运用与football的同义关系推断为“足球”。

例11.There is no reason to insult and defame the man simply because you do not agree with him.

[分析]根据与insult“侮辱”的同等关系猜测defame为“诋毁” ，“中伤”或“诽谤”
