【题目】读日本某地农业循环经济模式图,完成下列小题。

1图中箭头①、②、③分别表示

A. 饲料、燃料、肥料B. 饲料、肥料、燃料

C. 燃料、饲料、肥料D. 燃料、肥料、饲料

①维护农业生态平衡 ②改善农田施肥结构

③增加农民经济收入 ④实现污染物零排放

A. ①②③B. ①②④

C. ①③④D. ②③④

【答案】

1B

2A

【解析】

1本题考查循环农业的特点。读图,①为榨油之后的油渣等,是家畜饲养的良好饲料;家畜粪尿经过堆肥化可形成有机肥料②,施用到油菜、水稻田;食堂废油经过加工之后可以生产生物柴油,作为燃料③用到农机的农业生产中,所以从而实现了物质循环。所以B项正确。

2本题考查循环农业的好处。通过发展农业循环经济,减少废弃物的排放,减少农药化肥的使用,可以①维护农业生态平衡,②改善农田施肥结构;变变废为宝,增加农产品种类,③增加农民经济收入 ,故A项正确。在生物燃料在农机、公交车使用中,仍然有燃烧废气等排出,所以不能实现④污染物零排放。故BCD项错误。

图中指向公交车和指向农田的是同一类产品。

【题目】

It could be said that the age of adventure peaked with Sir Everest Shackleton the moment his ship, the Endurance, become hopelessly locked in ice on its way to Antarctica in January 1915. For ten months the 28 men aboard Shackleton’s ship waited and prayed for ice to break. When it finally did, the Endurance sank, leaving the crew homeless and adrift on a sea of ice in one of the world’s most dangerous environments.

In January 2000 a luxury ocean liner found itself similarly trapped in the cold waters off Antarctica. Argentine authorities sent off an icebreaker straight away from the nearest naval base, and in 24 hours, all 176 passengers and crew were free. The tour company’s spokesperson spun the potential disaster as a value-added reward in extreme travel. “The people on board are looking at this as sort of a great adventure,” she said.

Ever since Jon Krakauer’s book Into Thin Air made Everest a household name, the subculture of adventure has blown up like a Himalayan avalanche(雪崩) into public consciousness. Magazines promise “extreme” content, television, offers adventure programs, and the growing collective fascination with adventure has produced a flow of published accounts about the world’s greatest adventurous journey. Nowadays more and more people are interested in adventure and this mass appeal makes good business sense. Today the only thing blocking a would-be adventurer’s passage to Antarctica is the cost---- which typically runs well over $10,000.

Despite very different implications, adventure was just as popular in Shackleton’s time. He has little trouble filling the Endurance----5,000 men are said to have responded to his recruitment(招募) notice: “Men wanted for risky journey. Small wages. Bitter cold. Long months of complete darkness. Constant danger. Safe return doubtful.”

After five months drifting on ice, the crew were forced to take to their lifeboats to Elephant Island. Reaching the wasteland, Shackleton went on with one lifeboat and five of his best men 1,300 kilometers across the bone-chilly Scotia Sea to South Georgia Island. Shivering with cold, dressed in rags, Shackleton marched into a whaling station and set about organizing a rescue expedition to Elephant Island. Almost two years after becoming shipwrecked on ice, Shackleton picked up his crew. “Not a life lost, and we have been through hell,” he remarked earnestly.
