一、针对性解释
1、根据定义猜测词义
假如生词是句子或段落所解释的定义,理解句子或段落本身就是推断词义。
【例一】anthropology is the scientific study of man.
【例二】In slang the term "jam" constitutes a state of being in which a person finds himself or herself in a difficult situation.
同样,从上下文的定义可知jam一词在俚语中的意思是“困境”。
定义句的谓语动词多为:be, mean, deal with, be considered, to be, refer to, be called, be known as, define, represent, signify, constitute等。
2、根据复述猜测词义
