英语单词大多是由词根、词头(前缀)和词尾(后缀)所组成。
词根是单词最基本的部分,表达单词的基本含义。
在词根前或后加上前缀或后缀,可以用来引申或转变原词的意义。
只要我们掌握了各种词根、词头和词尾的基本含义,那么就可以很容易猜测出由其构成的新词的含义了。
中学英语中常见的前缀和后缀有:
super-(超)mini-(极小的,微小的)micro-(极微小的)re-(再,反复)mis-(误,恶)im-(不)un-(不,非)in-(不,非)non-(不,非)-able(能的)-less(不,无)-wards(向),supermanmicrowave(超人)nonnaturalmispronouce(非自然的)homelessnonsmoker(无家可归的)rebuildeastwards(重建),Canyouguesstherightmeanings?

利用语境及前后的提示来猜测词义。
A,(n.猫头鹰),A,(n.猿),8.Commonsense普通常识:
根据普通常识和生活经验来猜测词义。
在阅读的过程中,如遇到生词,有时可以根据自身的直接或间接的经验,或运用自己已有的常识将其推测出来。
比如了解一些英美国家的天文地理、风俗习惯、宗教信仰、政治结构、社会制度等,可以帮助加深对文章的理解,遇到生词时,猜测词义的能力自然就会增强。

有些常用词在特定的上下文中,或专业性文章中,具有特殊的或专门的词义。
在解这类题时,必须仔细地研读划线部分的上下文,有时阅读的视线还要扩大一些。
如果离开特定的语言环境来理解生词意义,必然会理解错误。
