从考卷到车厢的字母失踪案
When students receive their exam results, they often see grades like A,
B, C, D, and F. But have you ever wondered why there's no 1 grade?
Similarly, if you've travelled 2 train, you might have noticed that seats
are labeled A, B, C, D, and F, but E is missing. What's the reason behind
this?

The Missing E Grade in Exams
In the grading system used in many schools, A is the highest score, followed by B, C, and D. F
stands for "fail", meaning the student didn't 3 the exam. But why is there no E? The answer lies
in history. When the grading system was first 4 (create), educators wanted to make a clear
distinction between passing 5 failing. They decided to skip E to avoid confusion. E is too close
6 F, making it harder for students and parents to understand whether they passed 7 failed.
By skipping E, the difference between D (the lowest passing grade) and F (fail) became clearer.
The Missing E Seat on Trains
The 8 (same/different) logic applies to train seats. When trains were first designed, seat
labels followed the order of the alphabet: A, B, C, D, and so on. However, E was often skipped to
avoid confusion. For example, on planes, 9 (/si:ts/) are labeled A, B, C, D, F, and so on, with
E missing. This is because E could be easily confused with F, especially in noisy or crowded
environments. By skipping E, passengers can find their seats more 10 (quick) and avoid mistakes.
Next time you see your exam results or board a train, you'll know why E is missing!

二、新考法 应用实践 在教室或家中用纸板制作"火车座位"(标 ABCDE 和 ABCDF),让 3 名同学(或家人)找座位。
Hypothesis(假设): People can find their seats more quickly and accurately when the seat labels skip the letter
Result: With E: 可以结合实际情况作答。秒
Without E: 秒
Conclusion(结论): Skipping E can help people find their seats more quickly and reduce mistakes..

答案： 一、1.E 句意：但你有没有想过为什么没有E等级？根据“The Missing E Grade in Exams”可知，此处指没有E等级。故填E。
2.by 句意：同样，如果你坐火车旅行，你可能会注意到座位被标记为A、B、C、D和F，但没有E。根据“if you’ve travelled”可知，此处表示乘坐火车旅行。by train“乘火车”，固定搭配。故填by。
3.pass 句意：F代表“不及格”，意味着学生未通过考试。空处位于助动词“didn’t”后，填动词原形。根据“F stands for ‘fail’”和“educators wanted to make a clear distinction between passing”可知，此处指考试没通过。pass“通过”，动词。故填pass。
4.created 句意：当评分系统最初被建立时，教育工作者想要明确区分及格和不及格。create“创造”，动词。主语“the grading system”和动词create是逻辑上的动宾关系，此句用被动语态，且此句结构为was done。create的过去分词是created。故填created。
5.and 句意：当评分系统最初被建立时，教育工作者想要明确区分及格和不及格。根据“between passing”可知，此处指在及格和不及格之间进行区分。between...and...“在……与……之间”，固定搭配。故填and。
6.to 句意：E和F太接近了，这使得学生和家长更难了解他们是通过了考试还是没有通过考试。根据“making it harder for students and parents”可知，由于E和F很接近，容易混淆。close to“接近”，固定搭配。故填to。
7.or 句意：E和F太接近了，这使得学生和家长更难了解他们是通过了考试还是没有通过考试。根据“passed”和“failed”可知，此处表示选择关系，表示通过或者没通过，填表示选择关系的连词or。故填or。
8.same 句意：相同的逻辑适用于火车座位。根据“When trains were first designed, seat labels followed the order of the alphabet: A, B, C, D, and so on.”可知，火车座位没有E等级的原因与分数系统相同。用same“相同的”。故填same。
9.seats 句意：例如，在飞机上，座位被标记为A、B、C、D、F等，没有E。根据音标可知，单词为seats“座位”，可数名词复数作主语。故填seats。
10.quickly 句意：跳过E，乘客们可以更快地找到他们的座位，避免犯错。空处修饰动词“find”，填副词作状语。quick“快速的”，为形容词，副词为quickly“快速地”。故填quickly。
二、Hypothesis: People can find their seats more quickly and accurately when the seat labels skip the letter
Result:可以结合实际情况作答。
Conclusion: Skipping E can help people find their seats more quickly and reduce mistakes.
