Although he left home early, but he was late. ( )
Although he left home early, he was late. ( )

percent 名词， 意为“百分之……” ，没有复数。
e.g. Eighty percent of the students in our class exercise every day.
我们班里80%的学生每天都锻炼。
基数词 + percent作主语,谓语动词以它所修饰的名词来判断谓语的单复数。
e.g.
Twenty percent of the workers _____(be) women.
Thirty percent of time _______(be) enough.
are
is
虽然，尽管
