关于主谓一致，Manhattan SC中提到

Subject Phrases and Clauses: Always Singular

Having good friends IS a wonderful thing.

刚刚做到prep08，看到一题

180.

Noting that the Federal Reserve had raised a keyshort-term interest rate again last month, analysts said that they expectedorders for durable goods to decline soon because rising interest rates makesit more expensive to buy them on credit

A.    rising interest rates makes it more expensive tobuy them on credit

B.    rising interest rates make buying on credit moreexpensive

C.    a rise in interest rates make it more expensive tobuy on credit

D.    a rise in interest rates make buying on credit moreexpensive    (B)

E.    a rise in interest rates makes it more expensivefor them to be bought on credit

这里同样是rising interest rates做主语，为什么谓语用plural形式？

怎么区分 晕了？

having good friends是动名词形式做主语
rising rates是rates作主语，rising只是形容词 ...
