强化阶段：听力数字陷阱 - 「分数 / 小数」辨听训练

在英语四级的备考过程中，听力部分一直是考生们比较头疼的一个环节。尤其是数字陷阱，常常让考生们在考试中失分。今天，我们将重点讲解如何在听力中区分分数和小数的表达，特别是 one third（1/3）与 0.3（three tenths）的辨听训练，并附上30例数字题辨听练习，帮助大家更好地应对这一难点。

一、分数与小数的基本表达

在英语中，分数和小数的表达方式有所不同。分数通常由“分子+序数词+of”的形式构成，例如 one third（1/3）、two fifths（2/5）。而小数则是用阿拉伯数字表示，后面加上“point”加小数部分，例如 0.3（three tenths）、1.25（one point two five）。

二、辨听技巧

1. 注意关键词：在听力中，分数和小数的表达通常会伴随特定的关键词。例如，“fraction”表示分数，“decimal”表示小数。听到这些关键词时，考生应提高警惕，注意接下来的数字表达。

2. 熟悉常用表达：对于常见的分数和小数，考生应做到耳熟能详。例如，one third、two thirds、a quarter、half、0.5、0.25等。

3. 练习快速反应：在听力考试中，时间非常紧迫。考生需要通过大量练习，培养快速反应的能力，能够在短时间内准确识别分数和小数。
