托福獨立寫作中因為詞匯運用不當(dāng)所導(dǎo)致的扣分問題層出不窮。很多同學(xué)并非不知道這些詞匯語法問題，許多情況下都只是沒有太過注意才會導(dǎo)致錯誤發(fā)生。下面和小編一起來看托福寫作中如何巧用詞匯，希望有所幫助！
數(shù)字/單詞運用時機區(qū)分
當(dāng)數(shù)詞可以用至多兩個英文單詞表達時，盡量使用英文字母表示。因此，12以下的數(shù)字或整數(shù)一般都需要“寫出來”，但在percent(百分比)前面一般直接使用阿拉伯?dāng)?shù)字，如：
Experts quickly realized that there were two possible explanations for the decline of sea otters: environmental pollution or attacks by predators. 專家很快認(rèn)識到，海獺數(shù)量減少有兩個可能的.原因：環(huán)境污染或來自捕食者的攻擊。
When the price difference between two products is small, for example, less than 5 percent in the case of eco-certified wood products, American consumers often choose on factories other than price. 當(dāng)兩種產(chǎn)品之間的價格差距非常的小(在環(huán)保認(rèn)證木材制品的案例中，這種差距小于5%)，美國消費者會考慮生產(chǎn)廠商而不是價格。
什么時候用阿拉伯?dāng)?shù)字
當(dāng)數(shù)字需要用兩個以上英文單詞表達時，盡量使用阿拉伯?dāng)?shù)字表示，因此年份往往是直接用阿拉伯?dāng)?shù)字進行表示，如：
These animals could run very fast, reaching speeds up to 125 kilometers per hour. 這些動物奔跑速度非�？欤梢赃_到每小時125千米。
Cane toads were introduced to Australia in 1935 with the expectation that they would protect farmers’ crops by eating harmful insects. 蔗蟾于1935年被引入澳大利亞，期待它們通過吃害蟲來保護農(nóng)民的莊稼。
句子開頭不用阿拉伯?dāng)?shù)字
句子的開頭一般不使用阿拉伯?dāng)?shù)字，如：15 couples were invited to participate in a survey that aimed to figure out the fatal elements leading to personal success.十五對夫婦被邀請參與到一項調(diào)查之中，該調(diào)查的目的是探究個人成功最重要的要素。
較好的表達方式為：Fifteen couples were invited to participate in a survey that aimed to figure out the fatal elements leading to personal success.
小數(shù)分?jǐn)?shù)用數(shù)字
表達小數(shù)(或分?jǐn)?shù))時，盡量使用數(shù)字，如：The government has spent over $12.4 million constructing new recreational facilities for local residents in the past few decades. 在過去的幾十年間，政府花費了超過1240萬元用于為當(dāng)?shù)鼐用窠ㄔ煨碌膴蕵吩O(shè)施。
