The race to select the Beijing 2008 Olympic mascot is heating up and from all accounts the panda is out in front. According to news reports, the Sichuan panda team is pulling out all the stops to get the giant panda chosen—not surprisingly, as most of the pandas in China can be found in Sichuan. (41)______.

So what does an Olympic mascot represent to the world？ The Sichuan team says that the giant panda represents the peace and harmony of the Olympic spirit, but is that what a panda really portrays？ What, after all, does a giant panda do all day？ It pulls down bamboo shoots and eats, and when it's not eating, it sleeps. That's it! That is all a panda does. (42)______.

Fortunately there are other candidates for the honor of representing the Beijing Olympics, including the Chinese tiger. Now there's a contrast with the panda! The tiger is sleek; the tiger is swift. When the tiger springs into action, one can see its muscles ripple with energy; When a tiger is hunting for food, first it stalks its prey, perhaps a herd of wild swine. Then it chooses a victim and cleverly plans its strategy for the chase. Carefully choosing its moment, the tiger takes off with power and speed, as much as 80 km per hour. (43)______. The tiger is sleek, strong, swift and uses clever strategy to achieve its goal. Is it not the ideal animal to represent the athletes who have planned and carried out Icing-term strategies to qualify for the Olympics？

(44)______. However, the tiger, like most predatory animals, is not truly vicious—this is a common misperception. Under normal circumstances it kills only for food. When hungry it goes after its prey with fierce determination. it not take fierce determination for an athlete to win a medal in the Olympics？

Some years ago, Shell carried out a very successful ad campaign in Canada and the US. The ads showed a tiger getting into the gas tank of an auto; the accompanying slogan was "Put a tiger in your tank!" (45)______. Nowadays China is amazing everyone with the power and speed of its economic development, far outstripping the other nations of the world. In the latest Olympics, the Chinese athletes surprised the world not only with the number of medals they won but also with the categories in which they won them. I would therefore argue that Beijing's 2008 Olympic mascot should be an animal that embodies the great qualities, power and speed, of the Chinese athletes and their homeland—the Chinese tiger.

A. One might say that the giant panda is fat and lazy! What if there is no bamboo？ Does it find other food？ No. When the panda's food disappears, the panda disappears. In fact, the giant panda is a very vulnerable animal and that is why today it is at risk of extinction. Do Chinese really want a fat, lazy animal for their Olympic mascot？

B. Everyone understood the message: the tiger meant extra power and speed for your car. The original Olympics in Greece brought together athletes in a fierce trial of power and speed.

C. Recently it was brought to my attention that the 1988 Seoul Olympics had a tiger mascot. Does this make the tiger ineligible for use in the 2008 Beijing Olympics？ In an informal poll of my friends and colleagues, I discovered that no one remembered the mascot of the 1988 games. In fact, they did not remember the mascot of the Sydney Olympics or even of this year's Athens Olympics.

D. They have created 29 possible panda designs for consideration by the Beijing Olympic organizing committee, which will be making the choice.

E. To be sure, the giant panda seems loveable whereas the tiger might be thought by some t

In the following article, some sentences have been removed. For Questions 41-45, choose the most suitable one from the list A-G to fit into each of the numbered blanks. There are two extra choices, which do not fit in any of the blanks.

Long before man lived on the Earth, there were fishes, reptiles, birds, insects, and some mammals. Although some of these animals were ancestors of kinds living today, others are now extinct, that is, they have no descendants alive now. Nevertheless, we know a great deal about many of them because their bones and shells have been preserved in the rocks as fossils.

41.______That kind of rock in which the remains are found tells us much about the nature of the original land, often of the plants that grew on it, and even of its climate.

When an animal dies, the body, its bones, or shell, may often be carried away by streams into lakes or the sea and there get covered up by mud. If the animal lived in the sea its body would probably sink and be covered with mud. More and more mud would fall upon it until the bones or shell become embedded and preserved. 42．______Thus it follows that there must be many kinds of mammals, birds, and insects of which we know nothing,

43．______Later forms are more complex, and among these are the sea-lilies, relations of the star-fishes, which had long arms and were attached by a long stalk to the sea bed, or to rocks. There were also crab-like creatures, whose bodies were covered with a horny substance, The body segments each had two pairs of legs, one pair for walking on the sandy bottom, the other for swimming. The head was a kind of shield with a pair of compound eyes, often with thousands of lenses. They were usually an inch or two long but some were 2 feet.

The shellfish have a long history in the rock and many different kinds are known. Of these, the ammonites are very interesting and important. They have a shell composed of many chambers, each representing a temporary home of the animal. As the young grew larger it grew a new chamber and sealed off the previous one. Thousands of these can be seen in the rocks on the Dorset Coast.

The first animals with true backbones were fishes, first known in the rocks of 375 million years ago. About 300 million years ago the amphibians, the animals able to live both on land and in water, appeared. They were giant, sometimes 8 feet long, and many of them lived in the swampy pools in which our coal seam, or layer, formed. 44．__\_About 75 million years ago the Age of Reptiles was over and most of the groups died out. The mammals quickly developed, and we can trace the evolution of many familiar animals such as the elephant and horse. 45．___

[A] The best index fossils tend to be marine creatures. These animals evolved rapidly and spread over large areas of the world.

[B] The amphibians gave rise to the reptiles and for nearly 150 million years these were the principal forms of life on land, in the sea, and in the air.

[C] Many of the later mammals, though now extinct, were known to primitive man and were featured by him in cave paintings and on bone carvings.

[D] Nearly all of the fossils that we know were preserved in rocks formed by water action, and most of these are of animals that lived in or near water.

[E] The earliest animals whose remains have been found were all very simple kinds and lived in the sea.

[F] Many factors can influence how fossils are preserved in rocks. Remains of an organism may be replaced by minerals, dissolved by an acidic solution to leave only their impression, or simply reduced to a more stable form.

[G] From them we can tell their size and shape, how they walked, the kind of food they ate. Very occasiona

联合国政府间气候变化专门委员会在2007年2月2日就气候问题发出了警告：从现在开始到2100年，全球平均气温的“最可能升高幅度”是1.8摄氏度至4摄氏度，海平面升高幅度是18厘米至58厘米。

英国著名智库国际战略研究所的报告认为，“如果温室气体排放仍得不到控制，其灾难性后果不亚于发生一场核战争”。

从1950年到2002年，中国化石燃料燃烧排放的二氧化碳占世界同期累计排放量的9.33%(同期发达国家排放量占77%，而此前的200年间，发达国家更是占到95%)；1950年到2002年的50多年间，中国人均排放量居世界第92位；从单位GDP二氧化碳排放的弹性系数看，1990年到2004年的15年间，单位GDP每增长1%，世界平均二氧化碳排放增长0.6%，中国增长0.38%。
