First of all, the explanation of the past
1 means that things happened in the past time, as opposed to "today", "past" refers to a certain day in the past and "past year" refers to a certain year in the past.
2. The past represents a certain period or era in the past, "past era" refers to a certain period in the past, and "past glory" refers to the glorious course of the past.
Before means before a certain point in time. "Past" refers to the past, and "past" refers to the past and the past.
Second, the evolution of the past.
The evolution of the word "yesterday" can be traced back to Oracle Bone Inscriptions's time. Its original meaning is dried meat, and some people think it comes from the rising sun on the grass. In bronze inscriptions, the glyph gradually approaches "day". By the time of Xiao Zhuan, the font of "Yesterday" had been basically finalized, no different from modern regular script and running script.
With the development of Chinese characters, the meaning of "past" has also evolved, from the initial expression of dry meat to the expression of the past and past events of time, and then to the expression of memories and feelings of the past.
Yesterday's example
1. The painful experience of the past has now turned into valuable wealth.
2. The dream of the past has now become a reality and a valuable asset.
3. The friendship in the past has become faint and intoxicating now.
The former campus was the cradle of our growth. We study, grow and make friends here. Now, although the campus has changed, the memory of youth will never fade away.
5. The resentment in the past has now turned into a smile.
6. The vows of the past have now become pale and powerless.
7. The faces of the past are now engraved with the traces of years.
8. The former lovers are now separated.
9. The joys and sorrows of the past have now become legends in the story.
10, once friendship, like a glass of sweet wine, is intoxicating. Now, although we have parted ways, the deep friendship still lasts forever.
