Why are so many people so afraid to fail? Quite simply because no one tells us how to fail so that failure (失败) becomes an experience that means growth. We forget that failure is part of the human condition and that every person has the right to fail.

      Most parents work hard at preventing failure or protecting their children from the knowledge that they have failed. One way is to lower standards. 60% of the parents choose this way. When a child finishes making a table, the mother describes it as “perfect” even though it doesn't stand still. Another way is to blame (责怪) others. If John fails in science, his teacher is unfair or stupid.

      There's a problem with the two ways. It makes a child unprepared for life in the real world. The young need to learn that no one can be best at everything, no one can win all the time, and that it's possible to enjoy a game even when you don't win. A child who's not invited to a birthday party, who doesn't make the honour list on the baseball team, feels terrible, of course. But parents should not offer a quick consolations (安慰), prize or say, “It doesn't matter.” Because it does. The young should be allowed to experience failure and be helped to come out of it.

     Failure never gives people pleasure. It hurts both grown-ups and children. But it can be really good to your life when you learn to use it. You must learn to ask “Why did I fail?” Don't blame anyone else. Ask yourself what you did wrong and how you can improve. If someone else can help, don't be shy about asking them.

    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 letters 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”．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 a time of great change for schools. As the 20th century began,growing cities 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.
