托福閱讀遇生詞 推測詞義少不了

托福閱讀考試遇到生詞是難免的，但又不能每次都去查詞典，因此在這個時候，我們就要猜詞義，利用一些技巧推測詞義。下面小編就介紹幾種生詞猜詞義的技巧方法。

1.根據(jù)定義、解釋猜測詞義

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.由后面的解釋我們可以得知：“carnivorous”的意思是“食肉的”;“herbivorous”的意思是“食草的”;“omnivorous”的意思是“雜食的”。

2.根據(jù)復(fù)述(同位語、定語等)猜測詞義

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.

后面的同位語告訴我們“desertification”的意思是“沙漠化。”

3.根據(jù)舉例猜測詞義

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”同屬“poultry：家禽”。

4.根據(jù)對比關(guān)系猜測詞義

Jane was talking with others while Eliza remained reticent all the time.

“while”是一個顯示對比的信號詞，“reticent”與“talking”相對應(yīng)，“reticent”：沉默的。

5.根據(jù)比喻關(guān)系猜測詞義

The hot-air balloon took off. It was as buoyant in the air as a cork (軟木塞) in water.

把熱氣球比作水中的軟木塞，說明“buoyant ”的意義：“漂浮;浮力。”

6.根據(jù)同義詞的替代猜測詞義

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

由“backwards”這一替代詞得知“retrograde”的意思：“向后的。”

7.有時也可根據(jù)一般性常識/生活經(jīng)驗猜測詞義

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

門太低，我的頭撞在“lintel門楣”上了。

8.也可根據(jù)詞形構(gòu)造猜測詞義

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

form是詞根, formation“形式”，mal-:構(gòu)詞前綴，可表示“壞、惡、不良”，還可表示“不、不正常、不當(dāng)、非法。”malformation的意思就應(yīng)該是“畸形。”更多的例子如：malnutrition: 營養(yǎng)不良;malconduct:(公職人員的)胡作非為;maladjustive: 引起失調(diào)的;不利調(diào)節(jié)的。

當(dāng)然，要想做到這一點，就必須掌握英語常用的前綴、后綴及詞根的意義。

其實，新托福閱讀的目的在于獲得整個句子、整個段落、乃至整個篇章的思想，而不是各個孤立的詞匯的意義。新托福閱讀考試中，考查的是考生對段落中心思想整體把握的能力，只要能獲得閱讀材料的主要信息，并隨后能用自己的話加以陳述，一兩個生詞不會有什么大礙。
