感情色彩词
所谓“感情色彩词”是指，句子的表述总会带有作者的感情色彩，最为明显的感情色彩可以分为好与坏。根据好与坏的感情色彩进行选项排除，可以避免做题的时候遇到不会的问题乱蒙的现象。
【例如】5. According to the author, the American economic situation is .
A. not as good as it seem.
B. At its turning point
C. Much better than it seems
D. Near to complete recovery
原文：Well, no gain without pain, they say. But what about pain without gain? Everywhere you go in America, you hear tales of corporate revival. What is harder to establish is whether the productivity revolution that businessmen assume they are pre-siding over is for real.
解题：根据划线处，我们会发现该句中“harder to do sth”表示的感情色彩是不好的，根据这一线索，我们很自然地就会选出A选项。
