Answer 1

答案：1．A;2．D;3．C;4．C;
解析：

(1)	细节理解题．根据第一段第三句“The country's farmers are getting older, and there are fewer people standing in line to take their place”可知，A项正确．
(2)	细节理解题．根据第二段第一句中“…is making stops at universities across the country in hopes of encouraging more students to think about careers in agriculture”可知，D项正确．
(3)	推理判断题．根据第五段中“Global demand is at an all-time record high, and global supplies are at all-time record lows”可推断Matt Rush认为，全球对农业的需要达到了最高，而全球的供应则达到了最低，故在农业上投资肯定会获利，即C项正确．
(4)	试题解析：句意理解题．根据最后一段第二句中“…this is a new time in agriculture-will motivate the next generation…”可推断此处表示的是“农业的新时机将会激励下一代来参与，即农民的平均年龄将会年轻化”，故C项正确． 　　长难句解析： 　　1．Deputy Agriculture Secretary Kathleen Merrigan sees an epidemic(流行病)sweeping across Americas farmland． 　　本句是see sb．/sth．doing sth．的复合结构． 　　2．Merrigan, a former college professor, is making stops at universities across the country in hopes of encouraging more students to think about careers in agriculture． 　　本句是介词短语in hope of doing sth．希望……． 　　3．The 21-year-old Best hopes his message-that this is a new time in agriculture-will motivate the next generation to turn around the statistics． 　　本句是his message 的同位语从句 　　4．Never before have we had the innovations( 创新)in technology which have led to agriculture in this country being the most efficient it has ever been,” 　　本句never 否定词放在句首，后面用部分倒装，the innovations的定语从句，which是关系代词． 　　考点：科技类－说明文 　　文章大意：本文是一篇科技文，主要介绍了美国在农业方面临农民人数少，年龄偏大的问题，同时还缺少专业大学生从事农业生产．该怎么样解决这个问题．
