[求助]定语从句语法求助

双喜

白勇　语法　Ｐ２２５　有一句话我不明白，请各位帮我看看．

如果关系代词ＷＨＯＭ或ＷＨＩＣＨ和一个含有介词的及物动词短语连用时，介词应放在关系代词的前面．如：

The collateral  against which farmers borrow to get through the harvest season.

问题：

１　该句子如果还原，against放在哪？

２　句子大概意思上一啥？

问题比较简单，但是一直困绕我，请大虾帮忙！

原句是这样的吧：Declining values for farm
equipment and land,
            the collateral
against which farmers borrow to get through the harvest season, are going to force many lenders to tighten or
deny credit this spring.

collateral：抵押物，担保物 即文中的farm equipment and land.

所以正常的语序是 Farmers borrow against the collateral to get through the harvest season.

整个句子的意思就是：农民是通过抵押农场里的设备和土地来（向出借人）贷款度过收获季节的，而这些抵押品价值的下降，使得出借人在这个春季收紧甚至取消了（对农民的）贷款。

个人意见，欢迎板砖
