I can't figure out the reading comprehension of junior high school English and Hangzhou senior high school entrance examination English 20 10.

1 I asked for leave from school before the operation. My mother prepared the best (important) day of my life for me. Everything I liked when I was seven years old, everything would make me smile. The day began with her words "Kate, I have a surprise for you".

My mother passed the operation smoothly. Looking back now, I know that the best day of life was the last. This may be the most special day I can remember her, the last day we enjoyed.

The operation was a success. Because his mother had an operation on this day, I don't know the result of the operation, so it may be the last day. The penultimate one can be thought of as other meanings, special, unusual and important. Just as very can be translated into key, it means the same thing (for example, at this moment), and the last one may be enough for the author and mother to separate, remember their time together and say that this is the last time we share together.

Personal opinion, for reference only.
