The Great Red Spot
One distinctive feature of the planet Jupiter is the Great Red Spot, a massive oval of swirling reddish-brown clouds. Were Earth to be juxtaposed with the Great Red Spot, our planet would be dwarfed in comparison, with a diameter less than half that of the Great Red Spot. The Spot’s clouds, most likely tinted red as a result of the phosphorus that they contain, circulate in a counterclockwise direction. The outer winds require six Earth days to complete the circumference of the Great Red Spot, a length of time indicative of vastness of the Great Red Spot.

答案：C
2.Which of the sentences below best expresses the essential information in the highlighted sentence in the passage? Incorrect choices change the meaning in important ways or leave out essential information.
A. The Earth’s outer winds move a distance equal to the circumference of the Great Red Spot. B. The outer winds of the Great Red Spot move more quickly than do those on Earth.
C. The Winds moving across the Great Red Spot finally change direction every six Earth days. D. The fact that the winds take so long to move around the Great Red Spot proves how big it is.
答案：D
Passage One (Question 1-2)
Camouflage
Camouflage is one of the most effective ways for animals to avoid attack in the treeless Arctic. However, the summer and winter landscapes there are so diverse that a single protective coloring scheme would, of course, prove ineffective in one season or the other. Thus, many of the inhabitants of the Arctic tundra change their camouflage twice a year. The arctic fox is a clear-cut example of this phenomenon; it sports a brownish-gray coat in the summer which then turns white as cold weather sets in, and the process reverses itself in the springtime. Its brownish-gray coat blends in with the barren tundra landscape in the months without snow, and the white coat naturally blends in with the landscape of the frozen wintertime tundra.

Passage Two (Question 3-6)
Post-it Notes
Post-it Notes were invented in the 1970s at the 3M company in Minnesota quite by accident, Researchers at 3M were working on developing different types of adhesives, and one particularly weak adhesive, a compound of acrylate copolymer microspheres, was developed. Employees at 3M were asked if they could think of a use for a weak adhesive which, provided it did not get dirty, could be reused. One suggestion was that it could be applied to a piece of paper to use as a bookmark that would stay in place in a book. Another use was found when the product was attached to a report that was to be sent to a colleague with a request for comments on the report; the colleague made his comments on the paper attached to the report and returned the report. The idea for Post-it Notes was born.
It was decided within the company that there would be a test launch of product in 1977 in four American cities. Sales of this innovative product in test cities were less than stellar, most likely because the product, while innovative, was also quite unfamiliar. A final attempt was then made in the city of Boise to introduce the product. In that attempt, 3M salesmen gave demonstrations of the product in offices throughout Boise and gave away free samples of the produce. When the salesmen returned a week later to the office workers, having noted how useful the simple little product could be, were interested in purchasing it. Over time, 3M came to understand the huge potential of this new product, and over the next few decades more than 400 varieties of Post-it products - in different colors, shapes, and sizes – have been developed.

2. 排除列举题
The geology of the Earth's surface is dominated by the particular properties of water. Present on Earth in solid, liquid, and gaseous states, water is exceptionally reactive. It dissolves, transports, and precipitates many chemical compounds and is constantly Line modifying the face of the Earth.
(5) Evaporated from the oceans, water vapor forms clouds, some of which are transported by wind over the continents. Condensation from the clouds provides the essential agent of continental erosion: rain. Precipitated onto the ground, the water trickles down to form brooks, streams, and rivers, constituting what are called the hydrographic network. This immense polarized network channels the water toward a single recepatcle: an ocean. (10) Gravity dominates this entire step in the cycle because water tends to minimize its potential energy by running from high altitudes toward the reference point, that is, sea level.
The rate at which a molecule of water passes through the cycle is not random but is a measure of the relative size of the various reservoirs. If we define residence time as the (15) average time for a water molecule to pass throught one of the three reservoirs— atmosphere, continent, and ocean—we see that the times are very different. A water molecule stays, on average, eleven days in the atmosphere, one hundred years on a
continent and forty thousand years in the ocean. This last figure shows the importance of the ocean as the principal reservoir of the hydrosphere but also the rapidity of water (20) transport on the continents.
A vast chemical separation process takes places during the flow of water over the continents. Soluble ions such as calcium, sodium, potassium, and some magnesium are dissolved and transported. Insoluble ions such as aluminum, iron, and silicon stay where they are and form the thin, fertile skin of soil on which vegetation can grow. Sometimes (25) soils are destroyed and transported mechanically during flooding. The erosion of the continents thus results from two closely linked and interdependent processes, chemical erosion and mechanical erosion. Their respective interactions and efficiency depend on different factors.
8. All of the following are example of soluble ions EXCEPT (A) magnesium (B) iron
(C) potassium (D) calcium 答案：B
The canopy, the upper level of the trees in the rain forest, holds a plethora of climbing mammals of moderately large size, which may include monkeys, cats, civets, and
porcupines. Smaller species, including such rodents as mice and small squirrels, are not Line as prevalent overall in high tropical canopies as they are in most habitats globally. (5) Small mammals, being warm blooded, suffer hardship in the exposed and turbulent environment of the uppermost trees. Because a small body has more surface area per
4
unit of weight than a large one of similar shape, it gains or loses heat more swiftly. Thus, in the trees, where shelter from heat and cold may be scarce and conditions may fluctuate, a small mammal may have trouble maintaining its body temperature.
(10) Small size makes it easy to scramble among twigs and branches in the canopy for insects, flowers, or fruit, but small mammals are surpassed, in the competition for food, by large ones that have their own tactics for browsing among food-rich twigs. The weight of a gibbon (a small ape) hanging below a branch arches the terminal leaves down so that fruit-bearing foliage drops toward the gibbon's face. Walking or
(15) leaping species of a similar or even larger size access the outer twigs either by snapping off and retrieving the whole branch or by clutching stiff branches with the feet or tail and plucking food with their hands.
Small climbing animals may reach twigs readily, but it is harder for them than for large climbing animals to cross the wide gaps from on tree crown to the next that
(20) typify the high canopy. A macaque or gibbon can hurl itself farther than a mouse can: it can achieve a running start, and it can more effectively use a branch as a springboard, even bouncing on a limb several times before jumping. The forward movement of a small animal is seriously reduced by the air friction against the relatively large surface area of its body. Finally, for the many small mammals that supplement their insect (25) diet with fruits or seeds, an inability to span open gaps between tree crowns may be problematic, since trees that yield these foods can be sparse.
2. Which of the following animals is less common in the upper canopy than in other environments? (A) Monkeys (B) Cats
(C) Porcupines (D) Mice
答案：D
During the seventeenth and eighteenth centuries, almost nothing was written about the contributions of women during the colonial period and the early history of the newly formed United States. Lacking the right to vote and absent from the seats of power, Line women were not considered an important force in history. Anne Bradstreet wrote some (5) significant poetry in the seventeenth century, Mercy Otis Warren produced the best
contemporary history of the American Revolution, and Abigail Adams penned important letters showing she exercised great political influence over her husband, John, the second President of the United States. But little or no notice was taken of these contributions. During these centuries, women remained invisible in history books.
(10) Throughout the nineteenth century, this lack of visibility continued, despite the efforts of female authors writing about women. These writers, like most of their male
counterparts, were amateur historians. Their writings were celebratory in nature, and they were uncritical in their selection and use of sources.
During the nineteenth century, however, certain feminists showed a keen sense of
