Peace and development remain the principal themes in today’s world, and the overall international security environment remains stable. But, uncertainties and destabilizing factors are on the increase, and new challenges and threats are continuously emerging. World peace and security face more opportunities than challenges. 1. The world is at a critical stage, moving toward multi-polarity. Progress is expected in addressing the serious imbalances in the international strategic alignment. The major international forces compete with and hold each other in check. But, they also maintain coordination and practical cooperation in their mutual relationships, and draw on each other’s strengths. Some major developing countries and regional groupings have grown in power, and the developing world as a whole is becoming stronger. 2. Economic globalization accelerates and science and technology make rapid progress; there are profound changes in the international division of labor, global and regional economic cooperation is being vigorously promoted, leading to increasing interdependence among countries. More dialogues are being conducted on traditional security issues, and cooperation in non-traditional security fields is developing in depth. To address development and security issues through coordination, cooperation and multilateral mechanism is the preferred approach of the international community. The United Nations’ status and role in world affairs are being upheld and strengthened. World wars or all-out confrontation between major countries are avoidable for the foreseeable future.The international community is increasingly facing comprehensive, diverse and complex security threats. The world is not yet peaceful. 3. Political, economic and security problems and geographical, ethnic and religious contradictions are interconnected and complex. Hegemonies and power politics remain key factors undermining international security. Non-traditional security threats present greater danger, and local turmoil caused by war is on and off, and some hotspots cannot be removed in a short time. The impact of economic globalization is spreading into the political, security and social fields. Global economic development is uneven, and the gap between the North and the South is widening. 4. Security issues related to energy, resources, finance, information and international shipping routes are mounting. International terrorist forces remain active, shocking terrorist acts keep occurring. Natural disasters, serious communicable diseases, environmental degradation, international crime and other transnational problems are becoming more damaging in nature.

The political crisis in Ukraine, where opposition protesters are burning campfires and setting up tents in the center of Kiev, is presenting a test for Russia, which gambled heavily on its neighbor’s presidential election.A defeat of the pro-Moscow candidate, Prime Minister Viktor Yanukovych, would humiliate the Kremlin one year after another former Soviet republic, Georgia, slipped from its influence, according to observers and political analysts.The Ukrainian upheaval echoes what happened in Georgia, where protests over vote rigging led to the resignation of a Moscow-linked president and a landslide victory of a young, western-educated and Western-oriented leader.For Moscow, the stakes are even higher in Ukraine. Unlike Georgia, Ukraine shares close ethnic and linguistic ties with Russia; Kiev, Ukraine’s capital, is the cradle of the Russian culture and the ancient capital of the first Russian state.President Vladimir V. Putin of Russia wants to forge a closer union between three Slavic nations Russia, Ukraine, and tiny, authoritarian Belarus and Ukraine is key to the plan, Russian businesses have major interests in Ukraine, which borders Russia to the west. The Russian military also wants to have Ukraine as an ally over which it can hold sway, not as a potential NATO participant, the analysts said.As other former republics turned away from Russia, Moscow “gets the feeling that Ukraine is its closest ally, with a symbolic significance,” said Marsha Lipman of the Carnegie Moscow Center. “Russia has given itself a goal of getting a controllable Ukraine. I'm afraid it won’t happen.”Putin quickly congratulated Yanukovych following Sunday’s vote, which pitted the prime minister against opposition leader Viktor Yushchenko. But Western observers reported voting fraud, and hundreds of thousands of Ukrainians rallied in protest.“If the crisis lasts, it will become a potential source of problems for Russia’s relations with the West,” said Alexander Pikayev, an independent political analyst in Moscow “Russia will have to share responsibility for the acute political crisis.”The Kremlin had come out early and strongly for Yanukovych before the election. Putin traveled twice to Ukraine, ahead of each round of voting. To support the official purpose of his first visit, attending anniversary celebrations of Ukraine’s liberation from the Nazis in World War II, the festivities were rescheduled for 10 days earlier than the actual date.Since the vote, the Kremlin’s propaganda machine has been in full swing. Russia’s Channel One television, controlled by the Kremlin like all other major networks accused the Ukrainian opposition of breaking the law by declaring Yushchenko the rightfully elected president.In his prime-time show, television commentator Mikhail Leontyev compared the Ukrainian opposition to Middle Eastern militants. “But this is not the Gaza Strip, and the chaos cannot go on indefinitely,” he said, warning that protest strikes would only hurt ordinary people.Russian television also aired reports on the anniversary of Georgia's “Rose Revolution” on Tuesday, saying the country was steeped in misery and poverty a year after the fall of the old government. Russian independent newspapers, however, which reach only a fraction of the TV audience, wrote about a different Georgia the same day telling how happy Georgians had decorated shop windows and restaurants with roses to celebrate.Many Russians view Ukraine’s powerful opposition as a kind of force that has disappeared in Russia under the increasingly authoritarian Putin administration.Russia has not had a seriously contested presidential election since 1996, when Boris Yeltsin narrowly defeated a Communist challenger. The political opposition here is fractured and marginalized, ousted from parliament in last year’s balloting closely directed by the Kremlin.Russian optimists hope a defeat of Yanukovych would force the Kremlin to reconsider its attempts to control political life in other former Soviet republics. Pessimists fear that his loss would only prompt the Kremlin to tighten its rule.“The stakes are high,” Lipman said. “It’s a question of whether Russia’s neighbor will be a Ukraine ruled not through democratic institutes but through administrative means, or a Ukraine that will embrace democracy.”1.By saying “For Moscow, the stakes are even higher in Ukraine”, the author means（）.2.As to Ukrainian election, which of the following is true?3.What's the meaning of the sentence “...the Kremlin’s propaganda machine has been in full swing”?4.What can be inferred from the passage?

Standing on the rim of the Grand Canyon, gazing across this giant wound in the Earth’s surface, a visitor might assume that the canyon had been caused by some ancient convulsion. In fact the events that produced the canyon, far from being sudden and cataclysmic, simply add up to the slow and orderly process of erosion.Many millions of years ago the Colorado Plateau in the Grand Canyon area contained 10,000 more feet of rock than it does today and was relatively level. The additional material consisted of some 14layered formations of rock. In the Grand Canyon region these layers were largely worn away over the course of millions of years.Approximately 65 million years ago the plateau’s flat surface in the Grand Canyon area bulged upward from internal pressure; geologists refer to his bulging action as up warping; it was followed by a general elevation of the whole Colorado Plateau, a process that is still going on. As the plateau gradually rose, shallow rivers that meandered across it began to run more swiftly and cut more definite courses. One of these rivers, located east of the upwarp, was the ancestor of the Colorado. Another river system called the Hualapai, flowing west of the upwarp, extended itself eastward by cutting back into the upwarp; it eventually connected with the ancient Colorado and captured its waters. The new river then began to carve out the 277-mile-long trench that eventually became the Grand Canyon. Geologists estimate that this initial cutting action began no earlier than 10 million years ago.Since then, the canyon forming has been cumulative. To the corrosive force of the river itself have been added other factors. Heat and cold, rain and snow, along with the varying resistance of the rocks, increase the opportunities for erosion. The canyon walls crumble; the river acquires a cutting tool, tons of debris, rainfall running off the high plateau creates feeder streams that carve side canyons. Pushing slowly backward into the plateau, the side canyons expose new rocks, and the pattern of erosion continues.1.What does the passage mainly discuss?2.According to the passage, the first phenomenon to contribute to the formation of the Grand Canyon was（）.3.Which of the following conclusions about the Grand Canyon can be drawn from the passage?4.The passage would most likely be found in a textbook on which of the following subjects?

People in the United States in the nineteenth century were haunted by the prospect that unprecedented change in the nation’s economy would bring social chaos. In the years following 1820, after several decades of relative stability, the economy entered a period of sustained and extremely rapid growth that continued to the end of the nineteenth century. Accompanying that growth was a structural change that featured increasing economic diversification and a gradual shift in the nation’s labor force from agriculture to manufacturing and other nonagricultural pursuits.Although the birth rate continued to decline from its high level of the eighteenth and early nineteenth century, the population roughly doubled every generation during the rest of the nineteenth century. As the population grew, its makeup also changed. Massive waves of immigration brought new ethnic groups into the country. Geographic and social mobility—downward as well as upward—touched almost everyone. Local studies indicate that nearly three-quarters of the population—in the North and South, in the emerging cities of the Northeast, and in the restless rural counties of the West—changed their residence ach decade. As a consequence, historian David Donald has written, “Social atomization affected every segment of society,” and it seemed to many people that “all the recognized values of orderly civilization were gradually being eroded.”Rapid industrialization and increased geographic mobility in the nineteenth century had special implications for women because these changes tended to magnify social distinctions. As the roles men and women played in society became more rigidly defined, so did the roles they played in the home. In the context of extreme competitiveness and dizzying social change, the household lost many of its earlier functions and the home came to serve as a haven of tranquility and order. As the size of families decreased, the roles of husband and wife became more clearly differentiated than ever before. In the middle class especially, men participated in the productive economy while women ruled the home and served as the custodians of civility and culture. The intimacy of marriage that was common in earlier periods was rent, and a gulf that at times seemed unbridgeable was created between husbands and wives.1.What does the passage mainly discuss?2.According to the passage, the economy of the United States between 1820 and 1900 was（）.3.According to the passage, as the nineteenth century progressed, the people of the United States （） .4.Which of the following best describes the society about which David Donald wrote?

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 modifying the face of the Earth.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 is called the hydrographic network. This immense polarized network channels the water toward a single receptacle: an ocean. 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 average time for a water molecule to pass through 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 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 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.1.According to the passage, clouds are primarily formed by water （） .2.The passage suggests that the purpose of the hydrographic network is to （） .3.What determines the rate at which a molecule of water moves through the cycle, as discussed in the third paragraph?4.All of the following are examples of soluble ions EXCEPT（） .
