    Read the following passage．Answer the questions according to the information given in the passage．

    　　(Reuters)－At least 115 miners were pulled alive from a flooded coal mine in north China after being trapped for over a week, eating bark to survive, prompting extremely happy officials to hail their survival a miracle．

    　　Officials said 153 miners were trapped in the unfinished Wangjialing mine, belonging to two of China's larger state-owned firms in Xiangning, Shanxi Province, after water gushed(喷, 涌)into the shafts last Sunday．

    　　Late on Sunday night and throughout Monday, the survivors were pulled out from a platform, where the rescuers had drilled a vertical hole to ensure oxygen in the water-flooded pit and send down bags of glucose(葡萄糖)．Thirty-eight miners were still missing．

    　　"It is a miracle," said Luo Lin, head of the State Administration of Work Safety．"The trapped miners stayed so firmly determined down the mine shaft, passing through eight days and eight nights to live．" The workers also survived by eating bark from pine wood used in building the mines, Chinese television said．

    　　The government had succeeded in encouraging thousands of rescue workers to pump out water and search for the miners．After that, the water level dropped low enough for rescue workers to enter the shaft．

    　　It was rare good news in China's dangerous coal-mining industry, the deadliest in the world with thousands killed every year in floods, explosions, collapses and other accidents．Shanxi Province is the heartland of that industry．

    　　Strong demand for energy and not strict safety standards have made China's mines often deadly places to work, despite a government drive to clamp down on(对……进行压制或取缔)small, unsafe operations where most accidents occur．

    　　Workers are tempted into(被诱惑去)the mines by wages that can be much higher than for many other jobs open to blue-collar workers and rural migrants．

    　　China has consolidated(合并)or taken over many private mines, which has helped cut accidents．According to official statistics, the number of people killed in Chinese coal mines dropped to 2,631 in 2009, an average of seven a day, from 3,215 in 2008．But the deadliest accidents are not limited to private firms．

    1．According to the second paragraph, what caused the serious accident?(no more than 6 words)

    2．How did the rescuers manage to send down oxygen and bags of glucose into the pit?(no more than 5 words)

    3．According to the passage, what measures does the government take to help cut accidents?(no more than 13 words)

    4．What is the news about?(no more than 12 words)

    The Panama Canal opened almost 100 years ago. More than one million ships have passed through waterway since 1914. It connects the Atlantic and Pacific oceans and reduces travel by about 13,000 kilometers and avoids the need for ships to sail around Cape Horn at the bottom of South America.

    Built from 1904 to 1914, the canal has seen annual traffic rise from about 1,000 ships early on to 14,702 ships in 2008. In total, over 815,000 ships have passed through the canal. It has been named one of the seven modern wonders of the world. More than forty ships pass through the canal each day.

    　　 Now, a major expansion project will permit more ships and bigger ships to pass through the canal. Jorge Quijano, the Panama Canal’s executive vice president of engineering, says, “the Canal is operating at its limit. The present canal has a total capacity of about 340 million tons a year that it can handle. With the expansion we expect to double that, over 600 million tons that we can handle in a year.”

    　 Ships pass through a series of locks. These locks raise a ship to the level of Gatun Lake at the canal entrance on the Atlantic side. They lower the ship back to sea level on the Pacific side. For years, shipbuilders limited the size of many ships so that they could pass through the Panama Canal. But now many shipping companies use bigger ships to transport more goods as a way to reduce costs. Mr. Quijano says the expansion project will allow many of these larger ships to use the canal.

    　 Workers are building the new locks alongside the old ones, which will remain in use. The existing locks are 305 meters long and 55 meters wide. The new ones will be 427 meters long and 55 meters wide. They will be able to handle ships with drafts(吃水量) of more than 15 meters. At present, ships can ride only 12 meters deep in the cannel.

    　 Engineers could not make the new locks too big. Mr. Quijano says the plans had to balance the size of the locks with the cost for ships to use the canal. “We had to look at the optimal size of vessel that would make the return on the investment of a high value to us. So we chose what size of vessels that could actually pay for this project.” Mr. Quijano said.

    　 The cost of the expansion is estimated at more than five billion dollars. The new locks are set to open in time to celebrate the 100th anniversary of the Panama Canal.

    51. We can learn from the first two paragraphs that the Panama Canal _______.

    　 A. was built close to Cape Horn　　　　　　　　　 　

    B. took a decade to be completed

    　 C. now sees a daily traffic of about 400 ships　

    D. is one of the seven wonders of the ancient world

    52. After the expansion of the Panama Canal, ________.

    　 A. there will be no limitation to the size of ships through it

    　 B. it will have a total capacity of 500 million tons a year

    　 C. the cost of transporting goods will be relatively low

    　 D. the charge of using the canal will be reduced

    53. What do we know about the new locks?

    　 A. They will be put to use in 2014.

    　 B. They will take the place of the old ones.

    　 C. Their length will be double that of the old ones.

    　 D. Ships with drafts of 50 meters can pass through them.

    54. What is the author’s main purpose in writing the text?

    　 A. To introduce the history of the Panama Canal.

    　 B. To show the importance of the Panama Canal.

    　 C. To report the expansion project of the Panama Canal.

    　 D. To celebrate the 100th anniversary of the Panama Canal.

    　　Anthropologists are scientists that study people who often lived hundreds or even thousands of years ago．Items those men, women, and children left behind when they died－everything from clothing to jewellry and tools－tell anthropologists a lot．And sometimes even their words survive．

    　　Experts believe that a discovery in Mexico is the oldest example of writing ever found in the Americas．The people who created it probably lived 3,000 years ago, long before Christopher Columbus arrived in the New World．

    　　Workers digging in a rock mine happened to notice a stone block with marks carved onto its surface．They found the large piece of stone near the city of Cascajal, Mexico, which was once the capital of an ancient people called the Ohnec．

    　　“There is a sign that looks very similar to a knife and another that looks like the chair of a King,”he explains．

    　　Houston, an expert on the writing systems of ancient cultures, says the discovery is exciting because“it makes clear that the Olmec could read and write．It is like hearing voices from the past．”

    　　But experts don't know exactly what the writing says．Finding other examples of Olmec writing could help decipher the puzzle．

    　　“We could have whole sets of ancient writing which will basically make ancient people speak to us directly,”says Houston．“There are many puzzles to be solved, and this is just one of them．”
