    他們試圖想出一個能夠提前完成任務的計劃.
    by是介詞,關系代詞緊跟在介詞之后時,不能用that,指物時只能用which,指人時只能用whom.而且不能省略.
    但如果介詞移到后面,則可以用that.而且,由于介詞后面的成分叫賓語,關系代詞作賓語時,只要不是緊跟在介詞之后就可以省略.
    上例可以說成:
    They tried to think of a plan which/that they could fulfil their task by ahead of time.
    或They tried to think of a plan they could fulfil their task by ahead of time.
