阅读下面材料，在空白处填入适当的内容(1个单词)或括号内单词的正确形式。

Diets have changed in China-and so too has its top crop. Since 2011, the country 61 (grow) more corn than rice. Corn production has jumped nearly 125 percent over 62 past 25 years, while rice has increased only 7 percent.

A taste for meat is 63 (actual) behind the change: An important part of its corn is used to feed chickens, pigs, and cattle. Another reason for corn’s rise: The government encourages farmers to grow corn instead of rice 64 (improve) water quality. Corn uses less water 65 rice and creates less fertilizer (化肥) runoff. This switch has decreased 66 (pollute) in the country’s major lakes and reservoirs and made drinking water safer for people.

According to the World Bank, China accounts for about 30 percent of total 67 (globe) fertilizer consumption. The Chinese Ministry of Agriculture finds that between 2005-when the government 68 (start) a soil-testing program 69 gives specific fertilizer recommendations to farmers - and 2011, fertilizer use dropped by 7.7 million tons. That prevented the emission(排放)of 51.8 million tons of carbon dioxide. China’s approach to protecting its environment while 70 (feed) its citizens “offers useful lessons for agriculture and food policymakers worldwide,” says the bank’s Juergen Voegele.
