托福阅读不认识的词怎么猜

对于参加托福阅读考试的同学来说，遇到不认识的单词是很正常的一件事，那么遇到不认识的词我们要怎么猜呢?这也是需要技巧哦!

一、利用上下文线索猜测词义

　　1、根据同义、反义关系猜词

　　Today' s teenagers seem to be more liberal in their ideas than their _______grandparents. A. freethinking B. traditional C. old D. happy

　　traditional与liberal意思相反，故选B.

　　2、根据句意或段落文章的上、下文猜测词义Klebold and Harris felt _______ and wanted to revenge against those who disliked playing together with them or laughed at them. A. discouraged B. ashamed C. tired D. separated根据下文的disliked playing together with them判断此处应为“感到孤立”，故选D.

　　二、利用构词法猜测词义(利用前、后缀及合成词猜词义)

　　1、用前、后缀猜测词义英语中的前缀、后缀构词颇多，且特定的缀往往表示特定的含义，把握住这一点，可起到以不变应万变的效果。

　　1)He had been overworking and fell ill at last. overwork是由前缀over-加动词构成，over有“超过、过于”之意，overwork意思是“工作过多，劳累过度”。再如，overburden负担过重，overcharge要价过高，overdo做得过分。英语中常用的前缀还有：

　　mis-错，误：misfortune不幸;mislead误导;mismanage处理不当 mid-中央：midnight半夜;midway半路under-低于：underdone半生不熟的;underestimate低估anti-反对：antibody抗体;anticyclone反气旋;antifreeze防冻剂

　　下面划线单词为常见后缀派生词：

　　1)You must stop dreaming and face reality.(-ty为名词的标志)

　　2)The country is trying to popularize education. (-ize为及物动词的标志，再如realize，modernize)

　　2、利用合成词猜测词义。

　　Family members take turns choosing a special activity for the evening， and everyonepartakes in for fun.根据短语构成及上下文意思看，此处partakes in相当于takes part in.再如break out-outbreak(名词爆发)，set out-outset(名词起始)，come in-income(名词收入)
