Passage One

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

Passage 2

People all over the world today are beginning to hear and learn more and more about the problem of pollution.

Everything changed, and what changed for the Beatles was their lives and their working habits, in the midst of the hysterical(歇斯底里的) following the band attracted. Because of the demand of the fans to see them perform, they played bigger and bigger venues (meeting-places) , especially in America. They played pop music’s first "stadium" concert—to 60,000 people in Shea Stadium.
But John, Paul, George and Ringo became increasingly unhappy that, because of the screaming of their fans, neither the band nor the audience could hear the music. Creatively frustrated and tired of the pressures of life under siege(围攻) from their fans, they retired from playing concerts in 1966 and decided to concentrate on recording.
It was

[单项选择]Passage Three

People often speak of fire as though it were a living creature--It grows, dances, needs oxygen, feeds on whatever it can find, and then dies. And when a forest fire rages out of control, threatening human lives and homes, it must be fought like a "wild animal." The fight is often desperate, since firefighters’ best efforts may be dwarfed by the fury of a large fire. But the fire’s own traits can be used against it.
The heated air above a fire rises in a pillar of smoke and burnt gases, pulling fresh air in from the sides to replace it. Firefighters use this fact when they "fight fire with fire." They start a fire well in front of the one which they are fighting. Instead of traveling on in front of the huge fire, the smaller fire is pulled back toward it by the updrafts of the larger blaze. As it travels back to meet the large
A. behind a forest fire
B. ahead of a forest fire
C. on the sides of a forest fire
D. all around a forest fire
