    When it comes to the letter grade on your test or homework, you might notice that there is no letter E. Have you ever thought about why that is so?

    In the A. B. C. D and F grading system, the first four letter are typically considered passing grades. An F in this system simply stands for "fail". The word "fail" happens to start with the letter F, which seems to leave out the letter E, The fact of the matter is that any letter can mean "not-passing" or "fail". Some schools have U grade for unsatisfactory", or I grade for "incomplete."

    Even with all this said, we should also point out that E grade actually has been used pretty commonly throughout the history of letter grades in the US.

    The first college in the US to use a letter grading system like the ones we use today is Mount Holyoke College. In 1897, they began to use the following grading scale:

A: 95-100% (excellent)   B: 85-94%(good)   C: 76-84%(fair)

D: 75%(barely passed)   E: below 75%(failed)

    We can see the inclusion of E instead of F.

    Gradually, the letter grading system became more popular throughout the US. However, many schools decided to drop the E grade and go straight to F. There is no evidence(证据)to really support this, but one possible explanation is that teachers were worried that some students and parents might mistake E for "excellent".

    Why do we have letter grades? Well, part of the reason is that they made grading simpler during n time of great change for schools. As the 20th century began, growing cites and an increase in immigration led to larger school classrooms. Most teachers at that time thought this new letter grading system was an easy, fair and clear way to grade students.

    Today, more and more people argue that letter grades don' t fully reflect(反映)student learning. However, as teachers try to improve grading methods, many parents continue to favor the letter grades they got as kids. They are familiar(熟悉) and easy for parents to understand. So while they might not be perfect, the letter grades probably aren't going away any time soon.

    Back in the old days, young men were expected to go out and find jobs to support their families. Most boys dropped out of school(辍学) early, and went to get jobs as teenagers. Some just aged 13 became factory workers or farmers.  

    When Mark Twain finished the fifth grade, he left school and went to work at a printing shop. Thomas Edison got his first job when he was 12. He was a newspaper boy. This way, Mark Twain and Edison were able to help their families financially (经济上), since they did not come from wealthy homes. 

    Although they went to work at a young age, they didn't give up their dreams. Mark Twain tried many different jobs in his life, and he got a lot of experiences which he used as foundations (根据) of his stories. Thomas Edison came up with the ideas of his inventions while calling out the news headlines (标题). 

    No matter what job you are doing, you may find you are preparing for the future. Take every chance you can, and maybe one day you will become the next Mark Twain or Thomas Edison!
