Question

I shall borrow the book ,if it is yours.用虚拟语气写出与将来相反的虚拟条件句

Answer 1

I should borrow the book if it were to be yours.

I should borrow the book if it should be yours.

不能用I should borrow the book if it were yours,这是对现在的虚拟

请参考虚拟语气谓语变化表

虚拟时间 主句谓语 IF从句谓语

将来 would(should/could)+do were to do/should do

现在 would(should/could)+do were/did

过去 would(should/could)+have done had done
