174. Often major economic shifts are so gradual as to be indistinguishable at first from ordinary fluctuations in
the financial markets.
A. so gradual as to be indistinguishable
B. so gradual so that they can be indistinguishable
C. so gradual that they are unable to be distinguished
D. gradual enough not to be distinguishable
E. gradual enough so that one cannot distinguish them
可以理解正确选项，只是在想选项D， 可不可以改成 not gradual enough to be distinguishable？ 还是依然不如直接用indistinguishable来的直接简洁呢？
谢谢啦。。。

enough to表示主观满足,在标准书面语中很少使用, 如果选项之中有so that，或者so as to可以直接排除enough to

明显不行啊，原句的意思是the shifts are gradual, 改了之后就是the shifts are not gradual。。。作者: lminj 时间: 2014-9-3 12:45
ron说过 不要试图fix 已有的选项 只考虑对错和问题所在
