6．______again later if the webpage you are looking for is temporarily unavailable．（　　）

A．

Try

B．

To try

C．

Having tried

D．

Trying

分析如果你浏览的网页暂时链接不上，等会再试试．

解答答案：A．
祈使句，表示命令，请求．不用主语，直接用动词开头．you are looking for是后置定语，修饰 the webpage，翻译的时候要放到前面去．这个句子是主系表结构．is是系动词．故选A．

点评祈使句是用来表示命令、请求、建议、号召等的句子，谓语动词用原形，句末用感叹号"！"或句号"．"．朗读时一般用降调．
祈使句主语是you，you常省略，但如果要特别强调对方或表达某种强烈的情绪时可以有主语或称呼语．
Be quiet．请安静．
You be quiet！你给我安静点！

10．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 2012statistics 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.1on 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．"

61．According to Matt Rush，American agriculture will provide opportunities for younger people becauseC．
A．the government will cover production costs
B．global food supplies will be even lower
C．investment in agriculture will be profitable
D．America will increase its food export
62．What do the underlined words"to turn around the statistics"in the last paragraph mean？C
