01 解题指导
What time is it now
When will the man take the plane
How much will the man pay
How often does the man exercise
常见的设问方式
此类考题通常涉及以下信息：
(1) 基数词、序数词、小数、百分数；
(2) 年代、日期、星期、小时、时刻；
(3) 速度、路程、距离、价格、金额、比例；
(4) 街道、楼层、车牌、房间及电话号码等。
1、解题指导
考点应对技巧（必杀技）
(1) 用阿拉伯数字做好记录；
(2) 注意近音干扰；
能分辨-teen与-ty，如：fifteen和fifty
(3) 注意信息词以及时间的提前与推后；
before, ago, ahead of, early, after, later, not…until, fast, slow, more, less, more than, over, left 等
(4) 认真分辨常用来限定数字的表达；
如times, twice, double, half, two thirds, quarter, couple, pair, as many/much as, discount, dozen 等；
(5) 确定数字之间的关系，进行简单计算。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。

例题： 2020年普通高等学校招生全国统一考试（全国Ⅱ卷Ⅲ卷） Text 4
W: Excuse me. Could you tell me what time Flight AF35 gets in
M: Well, it’s due in at 6:20 p.m. But the announcement said just now that it has a 30-minute delay because of the bad weather.
本题关键信息：“at 6:20 p.m.”和“30-minute delay”。解题技巧：注意对整体信息的获取，首先判断所给数字是否为题干询问内容，例如本题中给出的35为航班信息，并非飞机到达时间；其次通常直接给出的数字往往不是正确答案，需要进行进一步简单计算。

04 技巧提点
学情分析
S
1.对时间、金钱和数量等相关的数字表达不熟悉。
W
2.数字与计算题听力技巧欠缺，不能有效捕捉关键信息。
O
3.对平常专门听套题的听力课没有兴趣，也没有对数字与计算进行专门训练。
T
4.数字在听力中具有独特的 “表达规则”，这些规则若不熟悉，很容易直接导致误听
04 技巧提点
听前预测，明确方向
在听力材料播放前，快速浏览题目及选项，根据选项中出现的数字类型（如时间、价格、数量等），预测听力内容可能涉及的计算场景和数字关系。例如，若选项中出现 “30”“45”“$60”，可推测可能与商品价格计算相关，如打折、买多件优惠等；若选项是 “9:15”“9:30”“10:00”，则可能涉及时间计算，如推迟、提前等。通过预测，提前在脑海中构建相关计算框架，为捕捉关键信息做好准备。
P
04 技巧提点
听中捕捉，精准记录
聚焦关键数字：听力过程中，重点捕捉与题目相关的数字，包括基数词、序数词、分数、小数、百分数等。同时，注意数字的单位，避免因单位混淆导致计算错误。
关注信号词汇：留意暗示数字之间关系的信号词汇，这些词汇是进行计算的关键。
简洁有效记录：边听边用简洁的符号或数字记录关键信息，避免因记忆遗漏而影响计算。例如，用 “↑” 表示增加，“↓” 表示减少，“×2” 表示两倍，“/2” 表示一半等。对于复杂数字，可先记录近似值，后续再根据听力内容修正
W
04 技巧提点
听后计算，排除干扰
快速准确计算：听力结束后，根据记录的信息和题目要求，迅速进行计算。计算时注意运算顺序，避免因粗心导致计算错误。
识别干扰信息：听力材料中往往会出现一些与题目无关的干扰数字，因此，要结合听前预测和题目要求，对记录的数字进行筛选， 排除干扰信息，只保留与解题相关的数字进行计算。
验证答案合理性：计算完成后，将结果与选项进行对比，验证答案的合理性。
