- I am glad that I planted a tree.
It doesn’t seem to make sense to re-write this sentence as the following:
I planted a tree. I am glad that.
This doesn’t look like an instance of “that” as a relative pronoun. “That” as a relative pronoun usually follows a noun but “glad” is an adjective (subject complement). The clause “I planted a tree” is saying why “I am glad”.
S-expression: [that [am [I] [glad]] [planted [I] [tree [a]]]]
