怎么把这句含which的句子还原成不含which的句子?
the amount shall be payable on the date on which by the terms of the issue the same becomes payable.
这样对吗:the amount shall be payable on the date on the same becomes payable by the terms of the issue.

the amount shall be payable on the date (on which)=when by the terms of the issue the same becomes payable.
就是关系代词换成when就可以了(这是定语从句嘛)
