我想交叉引用某些文本中某个单词首次出现的行号。例如，给定一段文本：
LESSON I
In the traffic court of a large mid-western city, a young
lady was brought before the judge to answer a ticket given
her for driving through a red light. She explained to his
honor that she was a school teacher and requested an imme-
diate disposal of her case in order that she might hasten
on to her classes. A wild gleam came into the judge's eye.
"You are a school teacher, eh?" said he. "Madam, I shall
realize my lifelong ambition. Sit down at that table and
write 'I went through a red light' five hundred times."
其中，新词“disposal”出现在第 5 行，因此新词列表如下：
----------------------------------------------------
1. disposal (L.5)
2. hasten (L.5)
3. gleam (L.6)
...
----------------------------------------------------
如何交叉引用这样的数字？
