如何在托福独立写作中使用常用数量词？

托福独立写作词汇运用不当很容易导致扣分的连锁反应，今天上海新航道托福培训班就为大家讲讲托福独立写作常用数量词的常见用法，希望可以帮助大家找到扣分的解决方法。

小数分数用数字

表达小数(或分数)时，尽量使用数字，如：The government has spent over $12.4 million constructing new recreational facilities for local residents in the past few decades. 在过去的几十年间，政府花费了超过1240万元用于为当地居民建造新的娱乐设施。

什么时候用阿拉伯数字

当数字需要用两个以上英文单词表达时尽量使用阿拉伯数字表示，因此年份往往是直接用阿拉伯数字进行表示，如：

These animals could run very fast, reaching speeds up to 125 kilometers per hour. 这些动物奔跑速度非常快，可以达到每小时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年被引入澳大利亚，期待它们通过吃害虫来保护农民的庄稼。

数字/单词运用时机区分

当数词可以用至多两个英文单词表达时，尽量使用英文字母表示。因此12以下的数字或整数一般都需要“写出来”，但在percent(百分比)前面一般直接使用阿拉伯数字，如：

Experts quickly realized that there were two possible explanations for the decline of sea otters: environmental pollution or attacks by predators. 很快认识到，海獭数量减少有两个可能的原因：环境污染或来自捕食者的攻击。

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. 当两种产品之间的价格差距非常的小(在环保认证木材制品的案例中，这种差距小于5%)，美国消费者会考虑生产厂商而不是价格。

句子开头不用阿拉伯数字

句子的开头一般不使用阿拉伯数字，如：15 couples were invited to participate in a survey that aimed to figure out the fatal elements leading to personal success.十五对夫妇被邀请参与到一项调查之中，该调查的目的是探究个人成功最重要的要素。

较好的表达方式为：Fifteen couples were invited to participate in a survey that aimed to figure out the fatal elements leading to personal success.
