HOW TO BE AN EFFICIENT TEACHER? Wu Rongming No. 3 Senior High School 1、语境使词义单一化 英语词汇往往是多义的，但是在一定的语篇中只使用一个义项。 例如“ lie”是一个有多个义项的词，但是在“The boy lied that a hen was laying eggs.”这样的语篇中只适用一个义项“撒谎”。在“A hen was lying under the tree”中只适用“躺”这一个义项。 如“The boy lied that a hen lying under the tree was laying eggs.” 一个句子解释清楚一个词的多个义项。 2、语境使词义具体化 词义有概括性，如“class、family 、army”，词义可以指整体又可以指整类事物中的某些个或某一个个体，什么时候指整类，什么时候指个别成员由语境决定。例如：He has a big family，and his family are keen on sports.前一个 “family”指 “一个家庭”, 后一个 “family” 指”所有家庭成员”。 3、语境表现出词义搭配的选择性??? 如下例：He took my bag in error, while I took yours by mistake.他不巧错拿了我的包，而我错拿了你的包。 I’m very pleased with my own cooking .It has a pleasant smell and I’m sure it will please my husband.我对自己做的菜感到满意，菜闻起来不错，肯定能令丈夫高兴的。 4、 语境辨别近义词、反义词 （1）e.g The reason for his departure was that he wanted to look into the cause of the accident. （2）The doctor treated her headache with a new medicine, but didn’t cure her. （3）I used to be dependent on my parents.

The new textbook will be published next month. （3）Do you know where the meeting will take place? Do you know where the meeting will be held? （4）Housing price won’t rise this year.
