In May 2001, I found a job in New York at the World Trade Center. On September 11, 2001, I arrived at my building at around 8:30 a.m. I was about to go up when I decided to get a coffee first. I went to my favorite coffee place even though it was two blocks east from my office. As I was waiting in line with other officer workers, I heard a loud sound. Before I could join the others outside to see what was going on, the first plane had already hit my office building. We stared in disbelief at the black smoke rising above the burning building. I felt lucky to be alive.

从下面五个选项中选出能填入文中空白处的最佳选项。

    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 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%( nearly passed)         E: below 75% (failed)

    We can see the inclusion of E instead of F.

    Gradually, the letter grading system became more popular all over 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 think that letter grades don't fully show students' learning. However, as teachers try to improve grading methods, many parents continue to prefer the letter grades they got as kids, as they are familiar and easy for parents to understand. So while they might not be perfect, the letter grades probably aren't going away any time soon.
