第一句可否这么说：
Have you swum across the river last week?
Last week与过去时连用
只能用过去时或者过去完成时，因为后面有状语“last week”
你可以说Had you swum across the river last week
但你不能说Have you swum across the river last week?
关键词: last week,上星期,应该用一般过去时
应该是不能的,swim是一个短暂性的动词,不能用现在完成时.
学生一个...
last week是过去时的标志
现在完成时属于现在时的范畴，因此它不和过去的时态连用。去掉last week就没问题了。
