专四语法虚拟语气的例题？

Question

Much as ______, I couldn’t lend him the money because I simply didn’t have that much spare cash.答案是I would have liked to. 意思都懂，但从语法上，为什么从句的谓语是would have done， 主句的是could do？

Answer 1

Much as i would have liked to, i couldn't lend him the money. Because ....这里much as等于though，后面用过去将来时，i wouldn't have liked to 是对过去事情虚拟的主句，would have done 。虽然当时我想帮他（实际没帮），但我不能借他钱。因为没那么多闲余的现金。

Answer 2

没错呀，表示虽然我本来很想帮他: Although I would have wanted very much to help him，虚拟过去的必须要更提早一个时态。追问

我现在有点混乱了，因为对过去相反的虚拟语气，不应该是主句would have done，从句had done吗

Answer 3

would have liked to do sth 等于 would like to have done sth. 表示与过去事实相反的虚拟语气。意思是：尽管我很想（当时）借钱给他，...追答

Answer 4

这里的couldn't是表示can’t的过去式，不是虚拟语气里的那个couldn't

Answer 5

这个答案有点问题，看句子的意思 这个人的意愿并不是假想，只是动作是假想。
i would have lend him money, but i couldnt. 这才有逻辑吧
