Question: Li Denghai, with his muddy boots and tanned  face, may not look like he is one of China's famous agricultural pioneers. But the 61-year-old man from Shandong Province has made scientific breakthroughs , which made great contributions to China's food security . His main work has been in achieving the higher output of corn production. Li, who holds the world record for the highest output of summer corn, once says, "Corn has a life; it sings and dances. If you listen clearly, it can speak to you." He started his research in 1969 when he was 20 and just dropped out of a high school. He then read an article which pointed that corn output per mu in the USA was six times higher than that in China. He was shocked and set out to work on just a small piece of land _ to see if he could increase the output. He often went to the field with a flashlight late at night, if he had been away during the day. By careful nurturing   he managed to double the output. Li Denghai was awarded the "China Award for Significant Contribution to the Maize   Industry" in 2005, and the same year the company named after his own name came into the market on the Shenzhen Stock Exchange. Li, however, is never happier than when he is in the middle of his cornfields. "I can forget my tiredness when talking to my corns," he says.

Question: At first sight, you would think the collection of hundreds of color1ed shards  could be a work of abstract   art. But the objects are the contents of the stomach of a sea turtle that lost its battle with plastic pollution.     Environmentalists examined the stomach of the turtle found off the coast of Argentina. What they found is the symptom of the increasing threat to sea turtles from a human addiction to plastic.     Sea turtles often mistake plastic items for jellyfish or other food. Ingesting  ocean pollution can cause a digestive blockage  and internal cuts. The result can be dangerous, followed by death.     Humans produce 260 million tons of plastic a year. When those products are pulled into the sea's currents, the plastics are just broken into smaller pieces which are consumed by marine life at the bottom of the food chain. An examination of a green turtle found off Florida discovered that, over the course of a month, the animal's faeces  had contained 74 foreign objects, including "four types of balloons, different types of hard plastic, a piece of carpet-like material and two 2-4 mm tar balls." "The oceans have become on giant refuse bin for all manners of plastics. All sea turtle species may be seriously harmed. " according to the biologists Colette Wabnitz, from the University of British Columbia. "The symptom of this growing crisis can be seen inside and on sea turtles as well as their oceanic and terrestrial habitats. It is urgently necessary to directly confront the source of plastic pollution, redesign packaging and rethink the very idea of 'throwaway culture'."     Almost all marine   species, from plankton to whales, have ingested plastic. But, even in small quantities, plastic can kill sea turtles, the biologists said.     Fifty out of 92 turtles found dead, stranded on the shorelines of Rio Grande do Sul state in Brazil, had ingested a "considerable amount of man-made  _ ". The author mentions the "throwaway culture" probably in a(n)   _   tone. A) praising B) positive C) comedic D) ironic
