She must remain single until today．
What does the sentence mean? Is she married now? Or is she still single?
Thanks so much, riquecohen.
The sentence is taken from a grammar book written by a Chinese professor of English and no context was given.
I am not a teacher, nor a native speaker.
I would assume that she's following some religion rule and the author is aware of that, so he writes that she must remain single until today.
However I agree that the sentence is odd.
Possibly, but she has had to.... makes more sense in that context to me. Without any further context being given, I would say it's just not a very good sentence as it's supposed to be illustrating something, but is very unclear what that is.
