托福閱讀中遇到生詞很正常，平時練習中我們還可以查詞典，但若是在考試中遇到了影響句子或段落理解的生詞該怎么辦呢?此時只能靠猜。其實托福閱讀生詞猜測也是有技巧的，掌握猜詞技巧能大大提升猜詞的正確率。

托福閱讀猜詞技巧一 根據文中釋義猜

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”。

托福閱讀猜詞技巧二 結合同位語猜詞

后面的同位語告訴我們“desertification”的意思是“沙漠化?！?/p>

Since the fossil of the Anchaeopteryx, the first ‘bird’, was discovered in Germany in 1861, there has been continuous disagreement as to whether or not it could actually fly.

Anchaeopteryx — the first bird: “始祖鳥”

托福閱讀猜詞技巧三 根據文中例子猜

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”。

托福閱讀猜詞技巧四 通過對比關系猜

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，“reticent”：沉默的。

“agreed”與“dissented”形成對比。

托福閱讀猜詞技巧五 通過文中比喻猜

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。”

托福閱讀猜詞技巧六 通過替代詞猜

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。”

門太低，我的頭撞在“lintel門楣”上了。

由經驗得知“pillion”是motorbike的“后座、后鞍?！?/p>

托福閱讀猜詞技巧八 通過構詞法猜
