麻烦大神帮解释一下against在这句话中的用法.
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.顺便帮忙翻译一下就更好了～谢谢!
答
首先你得知道Loan Against Collateral这个术语的意思是抵押贷款,而collateral against是这个术语的一种比较常用的说法,所以I这句的意思是：农机和徒弟价值的下降,加上农场主为度过收割季所做的抵押贷款,都将迫使债权人在下个春季（this spring是下个春季的意思）缩减或停贷.
