B.尽管天色已晚,复旦大学的学生还在田里工作.这是让步状语从句的倒装句,为了表强调.构成：强调部分＋as/though＋主语＋谓语,although不能这样用.A项动词原形显然错.C项应为Late though it was或Though it was late（正常语序),D应为Although it was late

A，形容词后 as 从句表示尽管怎么样。尽管他来的这么晚，这个复旦大学的学生仍然继续工作。

B、adj+as+代词+v/be=though+代词+v/be+adj意为尽管……
本句意为尽管为时已晚，那个来自复旦的毕业生仍坚持在这个领域工作

B Late as it was
Late as it was=Though it was late尽管已经很晚了
