托福阅读遇生词 推测词义少不了

托福阅读考试遇到生词是难免的，但又不能每次都去查词典，因此在这个时候，我们就要猜词义，利用一些技巧推测词义。下面小编就介绍几种生词猜词义的技巧方法。

1.根据定义、解释猜测词义

We all know that ants are ferocious eaters. They differ widely in their diets and may be carnivorous, herbivorous, or omnivorous, meaning that some eat meat; others eat only plants while others eat a combination of both.由后面的解释我们可以得知：“carnivorous”的意思是“食肉的”;“herbivorous”的意思是“食草的”;“omnivorous”的意思是“杂食的”。

2.根据复述(同位语、定语等)猜测词义

Today, I’d like to talk about some of the changes land can undergo, specifically desertification, process through which land becomes part of a desert.

后面的同位语告诉我们“desertification”的意思是“沙漠化。”

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。”

6.根据同义词的替代猜测词义

Venus rotates retrograde, or “backwards”, spinning in the opposite direction of its orbit around the Sun.

由“backwards”这一替代词得知“retrograde”的意思：“向后的。”

7.有时也可根据一般性常识/生活经验猜测词义

The door was so low that I hit my head on the lintel.

门太低，我的头撞在“lintel门楣”上了。

8.也可根据词形构造猜测词义

More recently, scientists have documented an alarmingly high occurrence of frogs with malformations.

form是词根, formation“形式”，mal-:构词前缀，可表示“坏、恶、不良”，还可表示“不、不正常、不当、非法。”malformation的意思就应该是“畸形。”更多的例子如：malnutrition: 营养不良;malconduct:(公职人员的)胡作非为;maladjustive: 引起失调的;不利调节的。

当然，要想做到这一点，就必须掌握英语常用的前缀、后缀及词根的意义。

其实，新托福阅读的目的在于获得整个句子、整个段落、乃至整个篇章的思想，而不是各个孤立的词汇的意义。新托福阅读考试中，考查的是考生对段落中心思想整体把握的能力，只要能获得阅读材料的主要信息，并随后能用自己的话加以陈述，一两个生词不会有什么大碍。
