When learning materials are graded, they have been built in steps, so a beginner is not handed the same English as a strong student. Teachers talk about graded readers (books that use only easy words at first, then slowly let in more), graded exercises, and a graded course or syllabus. The picture is a ladder: you stand on one step until you can take the next.

When learning materials are graded當學習教材是graded分級的，they have been built in steps表示它們是按步驟一步步設計出來的，so a beginner is not handed the same English所以初學者拿到的英文不會 as a strong student跟程度好的學生一樣。Teachers老師 talk about graded readers會談到graded readers分級讀本，(books that use only easy words at first, then slowly let in more)（一開始只用簡單的字，之後慢慢加進更多字的書），graded exercises還有graded exercises分級練習，and a graded course or syllabus以及graded course or syllabus分級課程或課綱。The picture畫面 is a ladder是一座梯子：you stand on one step你站在一階上，until you can take the next直到能踏上下一階為止。

People also use graded more loosely for anything sorted by how hard or how advanced it is, not only school books.

People人們 also use graded more loosely也會把graded用得比較鬆一點，for anything sorted by how hard or how advanced it is用在任何依難度或程度分類的東西上，not only school books不只是學校用書。

Though actually, the same spelling is just the ordinary past of grade, “to give a mark”: She graded the tests. That is a different job. This word here is the “made for levels” one.

Though actually不過實際上，the same spelling這個拼法 is just the ordinary past of grade其實也可能只是grade的普通過去式，"to give a mark"意思是「打分數」：She graded the tests她graded了這些考卷（打了分數）。That這 is a different job是完全不同的另一回事。This word here這裡講的這個詞 is the "made for levels" one是「為程度分級而做」的那個意思。
