专家解读托福阅读揣摩生词法二：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。
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 everyone partakes 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) 。
3.根据举例猜测词义
After breakfast， many people go to church; but the children will be playing with their new toys， and the mother will probably be preparing the Christmas dinner. This includes poultry for the main course (e.g. chicken， turkey， duck， goose)， salads， breads， and vegetable， and features a variety of desserts， for example， pies， puddings， and ice cream.
“chicken， turkey， duck， goose”同属“poultry：家禽”。
4.根据对比关系猜测词义
Jane was talking with others while Eliza remained reticent all the time.
“while”是一个显示对比的信号词，“reticent”与“talking”相对应，“reticent”：沉默的。
5.根据比喻关系猜测词义
The hot-air balloon took off. It was as buoyant in the air as a cork (软木塞) in water.
把热气球比作水中的软木塞，说明“buoyant ”的意义：“漂浮;浮力。”
