我选了D，因为觉得单复数我不敢肯定，所以没想该是economy还是economies。往后面读觉得失业率是经济的一种表现，前后应该是包含关系，应该用有依附关系的with，用了and的话就变成并列了。 请问这个思路出错在哪里呢？是因为我理解错了句子关系还是因为这个点不是重点呢？ 如果这点不是重点，那我应该从哪个点找呢？ 谢谢老师。

录音里面老师是用借此短语修饰不太好，排除了D选项，可是我在做题的时候用，首先看到单复数问题，于是找暗示，看到后面未划线部分是 that of ,于是觉得应该是单数，就选了D For the last five years the Dutch economy has grown faster than Britain, France, or Germany, with the unemployment rate having remained well below that of the other three countries. Britain, France, or Germany, with the unemployment rate having remained have those of Britain, France, or Germany, and the unemployment rate remaining have Britain, France, and Germany, and the unemployment rate has remained the economy of Britain, France, and Germany, with the unemployment rate that has remained the economies of Britain, France, and Germany, and the unemployment rate has remained

这到题 我剩了 DE 字面上区别有ti do 和for doing觉得to do 表示还没做 选了e

如果c换成have those of Britain, France, and Germany, and the unemployment rate has remained，怎么选，什么时候加have，什么时候不加。
