Noting that the Federal Reserve had raised a key short-term interest rate again last month, analysts said that they expected orders for durable goods to decline soon because rising interest rates makes it more expensive to buy them on credit
A.    rising interest rates makes it more expensive to buy them on credit
B.    rising interest rates make buying on credit more expensive
C.    a rise in interest rates make it more expensive to buy on credit
D.    a rise in interest rates make buying on credit more expensive  
E.    a rise in interest rates makes it more expensive for them to be bought on credit

为啥B是对的也，主语是rising interest rates这个动名词做主语，谓语动词应该是单数啊。。

LZ:这里应该叫做现代分词做形容词。rising 修饰 rates。rates才是真正的主语。明显的啊

为什么不可以把rising当做动名词，理解为rising Interest rates （这个动作）makes buying more expensive呢？

------------------------

我看见别的帖子写了，如果是动名词，应该是raise，而不是rise

这里AE的them指代有问题，cd的谓语应该用单数，只有b是没问题的。个人觉得这里rising作为gerund和participle都可以吧，从逻辑意思来理解，做动名词说rising rates这个动作使buying on credit更贵也可以，做participle说一个rsing的rates让buying on credit更贵也可以吧。

还是请高手指教一下。

个人觉得rise是不及物动词，所以 rising interest rates 中的rising只能是adj了，所以中心词是rates 用复数

刚搜到有人在讨论这个题，我也不理解。
rise是可以做及物动词的。。

gerund和participle有啥区别。。
