Deputy Agriculture Secretary Kathleen Me

题型:阅读理解

题目:

Deputy Agriculture Secretary Kathleen Merrigan sees an epidemic (流行病) sweeping across America’s farmland. It has little to do with the usual challenges, such as flood, rising fuel prices and crop-eating insects. The country’s farmers are getting older, and there are fewer people standing in line to take their place. National agricultural census (普查) figures show that the fastest-growing group of farmers is the part over 65. Merrigan is afraid the average age will be even higher when the 2012 statistics are completed.

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. Aside from trying to stop the graying of America’s farmers, her work is made tougher by a recent blog posting that put agriculture at No. 1 on a list of “useless” college degrees. Top federal agriculture officials are talking about the posting, and it has the attention of agricultural organizations across the country.

“There couldn’t be anything that’s more incorrect,” Merrigan said. “We know that there aren’t enough qualified graduates to fill the jobs that are out there in American agriculture.”

In addition, a growing world population that some experts predict will require 70% more food production by 2050, she said.

“I truly believe we’re at a golden age of agriculture. Global demand is at an all-time record high, and global supplies are at all-time record lows,” said Matt Rush, director of the Texas Farm Bureau. “Production costs are going to be valuable enough that younger people are going to have the opportunity to be involved in agriculture.”

The Department of Agriculture has programs aimed at developing more farmers and at increasing interest in locally grown food. The National Young Farmers’ Coalition has also been pushing for state and federal policy changes to make it easier for new farmers.

Ryan Best, president of Future Farmers of America, has been living out of a suitcase, traveling the country and visiting with high school students about careers in agriculture. 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. “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,” he said. “There’s really a place for everybody to fit in.”

用“伏安法”测量一只小灯泡的电阻.

(1)如图是实验电路图,图上的圆圈表示电表,请在圆圈内填入相应的字母.

(2)某实验小组通过改变灯泡两端的电压,进行了三次测量,部分记录见上表.若电压表示数为2.50V时,电流表的指针位置如图所示,请你填写表格中的两个空格.

实验次数123
电压/V1.001.702.50
电流/A0.140.22
电阻/Ω7.17.7
(3)老师看了该小组的记录,提示说:你们注意到三次测量的电阻相差较大这个现象吗?通过交流,其他小组也都有类似现象:灯泡电阻随电压增大、亮度增强而增大.经讨论,同学们认识到:实验有误差是肯定的,但这个现象不能单纯用误差来解释.因为:如果是误差,那么三次测得的电阻值应该相差______(选填“较大”或“较小”),并具有______的特点(选填“逐次增大”、“逐次减小”或“时大时小”).后来,同学们注意到灯泡发热发光的特殊性,认为灯泡的电阻可能与______有关,并通过查阅课本得到了证实.
