The Antarctic is the most remote continent and the last
to be discovered, but it constitutes up about a tenth of the 【M1】______
world's land surface. It is also the only continent without an
indigenous human people. 【M2】______
In the past it had a warm climate, supporting luxury 【M3】______
vegetation and large animals, but the climate deteriorated
over the last 30 million years. Once a great continent 【M4】______
Gondwana had drifted apart sufficiently for a southern
circumpolar current to become established. This, the largest
ocean current in the world, cut off Antarctica from the warmer
oceans to the north and 'allowed the ice sheets in places over
four kilometers high, to develop. 【M5】______
This region is the earth's major heat sink and contains ninety
percent of the world's ice and nearly three-quarters of
its water. Only two percent of the continent is not covered 【M6】______
by ice, and the life retains a tenuous foothold there.
Nearly the half of Antarctica's coastline is hidden by 【M7】______
thick float ice shelves or glacier, and the rest is scoured 【M8】______
by icebergs down to depths of 15 metres. But below this level
there is a colorful marine world containing a great diverse 【M9】______
of life. Recent work has shown that the pack
ice supplies a surprising rich Winter habitat 【M10】______
for a number of small creatures.

Every geologist is familiar with the erosion cycle. No sooner has an area of land been raised alive sea-level than it becomes subject to the erosive forces of nature. The rain beats down on the ground and washed【51】the finer particles, sweeping them into rivulets and then into rivers and out to sea. The frost freezes the rain water in cracks of the rocks and breaks【52】even the hardest of the constituents of the earth's crust. Blocks of rock dislodged at high levels are brought down by the force of gravity. Alternate heating and【53】of bare rock surfaces causes their disintegration. In the dry regions of the world the wind is a powerful force in removing material from one area to another. All this is natural. But nature has also provided certain defensive forces. Bare rock surfaces are in【54】course protected by soil itself dependent initially on the weathering of the rocks. Slowly【55】surely, different types of soil with differing "profiles" evolve the main types depending primarily on the climate. The protective soil covering, once it is formed, is held together by the growth of vegetation. Grass and herbaceous plants,【56】long, branching tenuous roots, hold firmly together the surface particles. The【57】is true with the forest cover. The heaviest tropical down- pours beating on the leave of the giant trees reach the ground only【58】spray, gently watering the surface layers and penetrating along the long passages provided by the roots to the lower levels of the soil. The soil, thus protected by grass, herb, or trees, furnishes a quiet habitat for a myriad varied organisms-earth-worms that importantly modify the soil, bacteria, active in their work of converting【59】leaves and decaying vegetation into humus and food for the growing plants. Chemical action is constantly taking【60】. Soil acids attack mineral particles and salts in solution move from one layer in the soil to another.

Section B
Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.
Though it now seems merely an episode in the last year of World War I, the influenza pandemic of the autumn of 1918 was one of the three greatest outbreaks of disease in history. Only the plague of Justinian and the Black Death compare with it. A quarter of the world's population was affected; all in all, it killed 22 million people, almost twice as many as were killed in the war itself. In India, more people died from influenza in a few months than had died from cholera in twenty years. In the United States, half a million people died.
Through centuries, the course of epidemics has run from east to west. The 1918 influenza epidemic followed this pattern, reaching America last. Traditionally, Asia has been the matrix of disease, almost as though there existed, in the vastness of Mongolia, a permanent focus of infection which would erupt periodically into the rest of the world. Some doctors maintained that the influenza was introduced by Chinese labor battalions that landed on the coast of France. Some attributed it to Russian soldiers arriving from Vladivostock. Others thought it might have developed in Spain from an earlier bronchitis which was so prevalent during the spring that the name "Spanish" was given to the autumn influenza. There was even one tenuous theory that the disease sprang into being in an isolated Georgia training camp during the winter of 1917 and migrated westward until it had circumnavigated the earth.
Influenza is still a mysterious disease. No one yet knows whether it is one virus or several, why it occurs in cycle, or how and where it lies dormant between epidemics. There are theories of weather, theories of the wearing off of group immunity, and even a theory of determination by economic circumstances. The most generally held current explanation is, however, that a pandemic like that of 1918 arises when a new and explosive strain of virus develops through a spontaneous process of mutation or renewal.
What is this article about？
A．The Black Plague.
B．The flu epidemic of 1918.
C．The Plague of Justinian.
D．All epidemics.
Tulips are Old World, rather than New World, plants, with the origins of the species
lying in Central Asia. They became an integral part of the gardens of the Ottoman Empire
from the sixteenth century onward, and, soon after, part of European life as well. Holland,
in particular, became famous for its cultivation of the flower.
(5) A tenuous line marked the advance of the tulip to the New World, where it was
unknown in the wild. The first Dutch colonies in North-America had been established
in New Netherland by the Dutch West India Company in 1624, and one individual who
settled in New Amsterdam (today's Manhattan section of New York City) in 1642
described the flowers that bravely colonized the settlers' gardens. They were the same
(10) flowers seen in Dutch still-life paintings of the time: crown imperials, roses, carnations,
and of course tulips. They flourished in Pennsylvania too, where in 1698 William Penn
received a report of John Tateham's "Great and Stately Palace," its garden tull of tulips.
By 1760, Boston newspapers were advertising 50 different kinds of mixed tulip "roots."
But the length of the journey between Europe and North America created many
(15) difficulties. Thomas Hancock, an English settler, wrote thanking his plant supplier for
a gift of some tulip bulbs from England, but his letter the following year grumbled that
they were all dead.
Tulips arrived in Holland, Michigan, with a later wave of early nineteenth-century
Dutch immigrants who quickly colonized the plains of Michigan. Together with many
(20) other Dutch settlements, such as the one at Pella. Iowa, they established a regular demand
for European plants. The demand was bravely met by a new kind of tulip entrepreneur, the
traveling salesperson. One Dutchman, Hendrick van der Schoot, spent six months in 1849
traveling through the United States taking orders for tulip bulbs. While tulip bulbs were
traveling from Europe to the United States to satisfy the nostalgic longings of homesick
(25) English and Dutch settlers, North American plants were traveling in the opposite
direction. In England, the enthusiasm for American plants was one reason why tulips
dropped out of fashion in the gardens of the rich and famous.
Which of the following questions does the passage mainly answer？
A．What is the difference between an Old World and a New World plant？
B．Why are tulips grown in many different parts of the world？
C．How did tulips become popular in North America？
D．Where were the first Dutch colonies in North America located？
