Question

of couse we should areast him,but as he has a good record,we shall let him off this time
but作为并列连词前后时态应该一致啊!为什么we shall let him off this time.用将来时,而它的斌咧句we should areast him 用过去将来时?先说出来看看：由于as 引导的条件状语从句 用现在时,主句就用将来时!
我觉得我的两种想法都是对的,
有一个单词错了 应该是arrest逮捕

Answer 1

should在这里是一个虚拟语气词 而不是过去将来
of course we should arrest him,but as he has a good record,we shall let him off this time.
我们当然应该逮捕他,但如果他有个良好的记录,这次我们就必须放了他.
