专题突破01 数字与计算（听力专练）
数字与计算类试题是高考英语听力测试中的经典题型，主要考查对数字信息的捕捉、辨别和简单计
算能力。其内容多与日常生活场景相关，包括：日期、时间、年代、年龄、数量、价格、电话号码、门牌
号、航班号等。
常见题型包括：
辨别类：要求直接辨认对话中提到的特定数字。
计算类：需对听到的数字进行简单运算（如加减乘除、折扣、比较）后才能得出答案。
这就要求学生能够区分一些易混音, 如-teen 和-ty. 此外，听时还需留心一些与数字运算有关的信息词,
如：double, twice, half, dozen, quarter, score, plus, minus, add, multiply, divide, cut off, come to, add up
to 等。
常见的提问方式有：
1. What time...? When ...? What size ...?
2. How long ...? How old ...?
3. How fast...? How often...? How much / many ...? How far ...?
4. How soon ...? What is the number of...?
5. What is the price of...? What is the temperature ...?
技巧1 用阿拉伯数字做好记录
在紧张的听力过程中，用单词或汉字记录数字速度慢且容易写错。阿拉伯数字书写速度快、一目了然。
听到任何数字，立即用阿拉伯数字记下。例如，听到 "thirty-five dollars"，立刻写下 35$。如果对话
中涉及多个数字，简单地在数字旁边标注它代表什么。例如：听到原价和折扣：Original: 120$ | Discount:
20%听到不同人的年龄：M: 35 | W: 28 (男35 岁，女28 岁) 这样在最后计算或选择时，可以快速定位信
息，避免混淆。
技巧2 注意数字和日期的读法（聚焦“十几”和“几十”）
这是最常见的出题陷阱，区分它们是听懂数字的前提。
“十几” (-teen)：重音在第二个音节，尾音 /tiːn/ 发音长而清晰，有明显的鼻音 /n/。如：thirteen,
fourteen, fifteen
“几十” (-ty)：重音在第一个音节，尾音 /ti/ 发音短促而轻，像快速说一个“提”字，没有拖长的
鼻音。如：thirty, forty, fifty
实战口诀：“长短音，分重音；有鼻音是十几，没鼻音是几十”。
技巧3 注意信息词以及时间的提前与推后
强化训练
这些关键词直接决定了数字是需要“加”还是需要“减”，是解题的关键。
表示“提前、减少、之前”
( 需用减法
) ：before, ago, early, fast (快), discount (折扣), off, save, less
例句：The meeting is 10 minutes early. (会议提前了10 分钟。)
表示“推后、增加、之后”
( 需用加法
) ：after, later, delay, postpone, slow (慢), more, add, plus,
another, extra
例句：The flight is delayed for 2 hours. (航班延误了2 小时。)
表示“倍数、分数、比较”
( 需用乘除法
) ：twice, double, times, half, one-third, a quarter
例句：The new building is twice as high as the old one. (新楼是旧楼的两倍高。)
技巧4 认真分辨常用来限定数字的表达
这些词times, twice, double, half, two thirds, quarter, couple, pair, as many/much as, discount, dozen
等，本身不是数字，但它们修饰数字，决定了数字的最终含义。
听到这些词要立刻警觉，它们后面的数字或它们修饰的数字很可能需要转换。如：
a pair of/couple of (一双/一对)：a pair of shoes for $80 → 最终价格是80 美元，而不是每只鞋40
美元。
a dozen (一打/12 个)：two dozen eggs → 数量是24 个。
half (一半)：half price → 价格是原价的一半。
double (两倍)：double the amount → 数量是原来的两倍。
20% off/discount (打8 折)：最终价格是原价的80%。
技巧5 确定数字之间的关系，进行简单计算
高考听力数字题99%都需要计算，直接给出答案的选项往往是干扰项。
运用前4 个技巧进行最简单的加减乘除。切记：答案往往不是对话中直接读出的那个数字！
Example (例题思维)：
录音内容：“This book is $20. But today we have a 15% discount for students.”
问题：How much should the student pay?
你的笔记：Price: 20 | Disc: 15%
计算：20 x (1 - 0.15) = 20 x 0.85 = 17
正确选项：$17. 而$20 和$15（混淆15%折扣）都是陷阱选项。
无论是哪种计算，其特点是计算较简单，一般不会超出口算和心算的范围。做题时，最好做简要笔记
。
在做这类题时学生往往容易听到什么就选什么，这样通常会导致错误。
