As one works with color in a practical or experimental way, one is impressed by two apparently unrelated facts. Color as seen is a mobile changeable thing depending to a large extent on the relationship of the color to other colores seen simultaneously. It is not fixed in its relation to the direct stimulus which creates it. On the other hand, the properties of surfaces that give rise to color do not seem to change greatly under a wide variety of illumination colors, usually (but not always) looking much the same in artificial light as in daylight. Both of these effects seem to the due in large part to the mechanism of color adaptation mentioned earlier. When the eye is fixed on a colored area, there is an immediate readjustment of the sensitivity of the eye to color in and around the area viewed. This A. the eye’s adaptation to color B. the properties of colored surfaces C. the effect of changes in color intensity D. experiments on colored objects [单项选择]Passage One
In one way of thinking, failure is a part of life. In another way, failure may be a way towards success. The “spider story ”often told, Robert Bruce, leader of the Scots in the 13th century, was hiding in a cave from the English. He watched a spider spinning a web.

Second , is the goal (目标) you’re trying to reach the right one Try to do some thinking about what your real goals may be. Think about this question, “If I do succeed in this, where will i
A. the value of failure B. how people would fail C. famous failures D. the cause of failure [单项选择]Passage Four
