This is a short story I read in the 1st grade, some 20+ years ago, that was included in our reading textbook.
What I remember is that the girl in the story was new to the area, possibly a Mars or Moon colony, and she was different than many of the students. For one, I believe she was green. She also spent time in a room with a giant skylight, because she got all of her energy from photosynthesis.
I don't remember if there was any plot besides that. I believe the story was actually used to segue into teaching us about plants, so there's the possibility this was a small excerpt of a larger work.
(It's not All Summer in a Day, but a recent question about that story reminded me of this one)
If it helps, I'm almost positive the textbook this was in also included the story Lose Now, Pay Later by Carol Farley. But, it was a grade-school textbook, not an anthology work (so, not 2041).
