Read the following article and select the best answer. Article: Throughout seafaring history, ships and sailors have been lost to storms, accidents and war. Until recently, most of these ships were weak wooden sailing vessel , their skeletons quickly eaten away by sea creatures. Now, large vessels made of steel float on the seas. Thousands of these huge ships have been lost in times of war and in times of peace. The bones of great metal ships, unlike the wooden vessels of old, survive the destruction of the sea long enough to become home and harbor for underwater life of all kinds. Shipwrecks often provide the only hard surface and structure at the sandy bottom of the sea, something many sea creatures need. The ship has been underwater for only five days. Its surface is still clean. Six weeks later, the wreck is covered with a slimy layer of algae , but it is still recognizable as a ship. Soon, animals that need to attach themselves to a hard surface, like the feather duster worms, make the wreck their home. In warm waters, coral polyps settle on the wreck and begin the process of building a rock-like _ on the ship. Small fish are attracted on all of these creatures. Larger fish come to feed on these small fish that hide in the wreckage. Eventually, the largest animals are attracted to the rich life on the shipwreck. Shipwrecks give us valuable information about how sea plants and animals develop. We know exactly how long this wreck has been under water and how long sea life has been growing on it. Yet even the strongest steel shipwreck will finally be destroyed by the flows of water. But long after this wreck has been broken apart, it will still act as a reef . Layer upon layer of sea life has formed a structure that is now more natural than artificial, and will remain an island of life under the sea. Question: The writer's purpose in writing the article is to tell us _ . - the differences between the ancient vessels and the modern ones - how the ships become shipwrecks at sea - how coral polyps live on the wreck in warm waters - the value of studying shipwrecks at the bottom of the sea
the value of studying shipwrecks at the bottom of the sea

Read the following article and select the best answer. Article: His eyes nearly in tears from the crush of fellow travelers at Guangzhou's train station, Hong Tao said things were much better on Sunday, after days of waiting for a train to his home in Hubei province. "I think it's fine today, and everything is going smoothly," the 28-year-old said. "I thought it would be really crowded but it has turned out to be OK." Chinese authorities say they expect 1.3 million people to travel out of Guangzhou's train station over the next few days, as they rush to get home by Wednesday, the eve of Lunar New Year. Hong's optimism may have been helped by the blue skies that emerged over Guangzhou on Sunday for the first time in a week. Last week, a rare winter storm paralyzed China's transportation system as millions tried to get home to celebrate the holiday -- the only chance for many migrant workers to see their families all year. China's state-run Xinhua news agency said Friday that 95 percent of rail traffic had "returned to normal." But Guangzhou's train station remained packed with a backlog of hundreds of thousands of travelers hoping to get home for the holiday. A young woman was stepped on in a stampede at the train station Friday, and later died of her injuries, according to Xinhua. Video of the situation on Friday showed crowds of people screaming, elbowing each other, in some cases sobbing and collapsing in the rush to get a slot (,) on a train. China Sunday announced it has organized over 300,000 People's Liberation Army forces to southern China in what it described as a "war on winter weather". The government also announced a $700 million plan to help farmers whose crops have been destroyed. Question: How many days is it from the day this article was made to the Lunar New Year? - Two days. - Three days. - Four days. - Five days.
Five days.

Article: Jonny Jones was a nice and popular boy, who everyone loved.He was so much fun, so good and so kind to everyone that they treated him wonderfully. But as everything he needed was given to him without asking, Jonny became a _ . He was so spoiled by everyone that he couldn't stand any hardship. One day Johnny heard a mother saying to her son "Come on, my boy, get up and stop crying. You are behaving like Johnny Jones." That made Johnny feel very ashamed. But he was sure that he would prefer to be known as a good boy rather than a fool. Worried, he spoke to his father about all this, though he was afraid that maybe he would be laughed at for having such worries. His father, far from laughing at Johnny, told him that a teacher had taught him a secret trick to turn him into the toughest boy off all. "Eat a candy less, study a minute more, and count to five before crying." Johnny asked, "Just that? " "Yes, just that," said his father, "It's very simple, but I warn you that it won't be easy." Johnny was happy like a bird, ready to follow the advice. He went to see his mother, and she noticed how happy he was when she offered him candies. "One candy less", thought Johnny, so he only took one. That afternoon he had another chance to put it into practice by studying one minute more. The result was that he missed the first minute of his favorite program! But having achieved this gave him a great feeling of satisfaction. The same happened when he ran up against the corner of the kitchen table. He only managed to count to four before crying, but that was left deeply in his mother's memory. Over the following days Johnny kept using the motto in his life as his father told him. And the more he put this into practice ,the easier it got.
