小虾米请教XDF 紫皮书语法第16题,谢谢

16.Declining Values for farm equipment and land,the collateal against which farmers borrow to get through the harvest season,is going to force many lenders to tighten or deny credit this spring.

此题考点是主谓一致,values 应该对应are,但我搞不清这个插入语,against 和which,还有这句插入语的意思,请教大家,

还会有很多题会请大家帮忙, 谢谢

谢谢你,好的,我慢慢总结.以后碰到类似这样的题,我先看主谓,插入语先不管了,以后有时间再慢慢研究.

有些问题会问得比较弱一些,希望大家不要见笑...不耻下问

帮忙顶，不重复发帖了，

1 the collateral这句话的插入语是什么作用

2 against 和which怎么理解？

3 翻译一下：农民借用农场机器和土地作为抵押以度过丰收的季节，由于农场机器和土地的贬值，迫使债主们缩减或拒绝贷款这个春天。

不知道这么理解对不对，谢谢！
