You should say:
When this happened;
What you forgot to do;
Who you were with;
and what consequences you faced.
题目解析：考官要听你说忘记的一件重要的事情。什么样的事情是重要的，那要看你怎么去说了，比如forgot my keys ， forgot to water my plants, 或者更重要的事情， 比如：forgot the flight, forgot father’s day, forgot my mother’s birthday
重要到什么程度?你可以忘记吃饭，忘记带钥匙，忘记浇花，忘记带手机，但绝对不可以忘记这件事，这件事对我来说意味着什么。
注意事项：这是一道事件题，会考查到大家的时态表达，在保证语速适中没有太多停顿的前提下还要保证时态基本准确，实际上还是比较有难度的，已经发生了的事情必然要涉及到过去时，要注意-ed形式和不规则的动词过去式。
思路解析：
what: 先开门见山告诉考官你忘记的事情是什么?
How: 整件事情的起因-经过-结果是什么。本来你还记得，因为什么事情不小心忘记了，之后又是怎么想起来的，做了什么去补偿的?
what： 最后可以讲这件事给你留下的印象很深刻，此后再也没有忘记过之类的。

I forgot my mother’s birthday last year. That was the most unthinkable thing for me because I had never forgotten her birthday before. It was actually the time really close to my final exam and I was preparing for it. I thought I wouldn’t forget her birthday and I planed to make her a cake and prepare a hearty meal for her. But I forgot it somehow just on the birthday. I was really busy with my revisions and stuff. When I got home after school my dad reminded me of her birthday. The very first thing I did was that I wrote a sorry card to her. I made a list of all the reason I was glad I got her as a mother and put it in the card. Mom wasn’t really upset.
I actually know there are plenty of things I am allowed to forget. I can forget to feed my dog. I can forget my keys. I can forget the location of my favorite restaurant. But one thing I shall never forget is her birthday. For my mother, her family is everything and she rarely gets angry or shouts at us when she pisses off. I was terribly sorry for my carelessness. And I’ve certainly never forgotten my parents’ birthday since then.
