字源 FORM what the parts do
以 fixes the point you have read up to, the edge the foregoing sits above. 上 is the short stroke set above the ground line, the side above and the earlier one. Together they name the territory above that point in the text: everything already laid down.
故事 STORY a scene to remember it by
A finger rests on the line just read. Everything written above that finger has already been set down, and 以上 sweeps the whole block above it back into view as one thing.

例 · Examples
1由from以上的報告，我們可以知道can know / can see不同地區學生的學習差異learning differences。
From the above report, we can see the learning differences of students in different regions.
以上 points up the page to what is already stated; 以下 points down to what is about to be stated. 以上是我的報告 closes a report just given; 以下是我的報告 opens one not yet read.
數量以上 (scalar bound: 兩個小時以上, that figure and up)
There the word before 以 is a quantity on a scale and 以上 means that figure and everything higher; here nothing sits before 以 (or it is 以上的+noun), and 以上 means the foregoing text, not a numeric range.
以下的報告 (when the report came earlier) ✗ → 以上的報告 ✓ (already-stated text is 以上, the side above)
上面報告 ✗ → 以上的報告 ✓ (the referential sense needs 以; bare 上面 leans toward a physical top surface)
由以上報告 ✗ → 由以上的報告 ✓ (以上 modifies the noun through 的)
English the above sits in front of its noun (the above report) and reads the same whether spoken or written. Chinese 以上 keeps that attributive order with 的, but stays anchored to text already on the page, so spoken open-ended use leans on 剛才/前面 instead.
