求助新PREP里的一道简单的SC题

帮楼主贴上：

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

rates是复数，谓语动词应该用复数形式啊...

请问楼上你的题目是手打的还是已经有破解版的新prep了？

rising在这时形容词修饰rates的。rates才是核心词

以下是引用aeoluseros在2008-12-23 22:35:00的发言：

应该很快就能出新的破解版了，还有些后续工作，再等几天

激动啊。。不过又多出无数题来了

请问版主我现在OG只做过OG11黄皮的所有题和prep破解语法，正准备做OG11紫皮的题。既然又要有新的prep了，我还有必要继续做剩下的两本OG吗？还是重点应该放在两个PREP上？

还有两个月考试，不过圣诞过了就没有大块时间来复习了。我总结的超级慢。准备最后一个月开始做GWD的。现在看来时间不太够

新题不多，三四十个吧，大概80来个在GWD里面了，剩下几十个是老prep里的。另外新的prep破解出来是为了方便大家提问。（严重剧透剧透...）

OG最好还是做一下而且我推荐多看两遍，官方的权威的解释都在里面。接下来最重要的还是《prep语法笔记》。新的prep暂时还没有类似《语法笔记》的出来，恰好可以当作模考题来挺不错，所以在GWD和新PREP，推荐还是以GWD为主，从prep的升级看GWD恰恰代表了一种命题趋势。

两个月时间够了，不过还是有点辛苦的，加油！
