问题    American farmers have been complaining of labor shortages for several years now. Given a multi-year decline in illegal immigration, and a similarly sustained pickup in the U. S. job market, the complaints are unlikely to stop without an overhaul of immigration rules for farm workers.
   Congress has obstructed efforts to create a more straightforward visa for agricultural workers that would let foreign workers stay longer in the U. S. and change jobs within the industry. If this doesn’t change, American businesses, communities, and consumers will be the losers.
   Perhaps half of U. S. farm laborers are undocumented immigrants. As fewer such workers enter the country, the characteristics of the agricultural workforce are changing. Today’s farm laborers, while still predominantly born in Mexico, are more likely to be settled rather than migrating and more likely to be married than single, They’re also aging. At the start of this century, about one-third of crop workers were over the age of 35, now more than half are. And picking crops is hard on older bodies. One oft-debated cure for this labor shortage remains as implausible as it’s been all along: Native U. S. workers won’t be returning to the farm.
   Mechanization is not the answer, either—not yet, at least. Production of corn, cotton, rice, soybeans, and wheat has been largely mechanized, but many high-value, labor-intensive crops, such as strawberries, need labor. Even dairy farms, where robots do a small share of milking, have a long way to go before they’re automated.
   As a result, farms have grown increasingly reliant on temporary guest workers using the H-2A visa to fill the gaps in the workforce. Starting around 2012, requests for the visas rose sharply; from 2011 to 2016 the number of visas issued more than doubled.    The H-2A visa has no numerical cap, unlike the H-2B visa for nonagricultural work, which is limited to 66,000 a year. Even so, employers complain they aren’t given all the workers they need. The process is cumbersome, expensive, and unreliable. One survey found that bureaucratic delays led the average H-2A worker to arrive on the job 22 days late. The shortage is compounded by federal immigration raids, which remove some workers and drive others underground.
   Petitioning each year for laborers—and hoping the government provides enough, and that they arrive on time—is no way to run a business. In a 2012 survey by the California Farm Bureau, 71 percent of tree-fruit growers and nearly 80 percent of raisin and berry growers said they were short of labor. Some western growers have responded by moving operations to Mexico. Without reliable access to a reliable workforce, more growers will be tempted to move south.
   According to a report by the Partnership for a New American Economy, Americans are consuming more fresh produce, which is good. But a rising share of it is grown elsewhere. From 1998 to 2000, 14. 5 percent of the fruit Americans consumed was imported. Little more than a decade later, the share of imported fruit had increased to 25. 8 percent. Rural U. S. communities that might have benefited didn’t.
   In effect, the U. S. can import food or it can import the workers who pick it. The U. S. needs a simpler, streamlined, multi-year visa for agricultural workers, accompanied by measures to guard against exploitation and a viable path to U. S. residency for workers who meet the requirements. Otherwise growers will continue to struggle with shortages and uncertainty, and the country as a whole will lose out.
One trouble with U. S. agricultural workforce is______.
选项 A、the rising number of illegal immigrants
B、the high mobility of crop workers
C、the lack of experienced laborers
D、the aging of immigrant farm workers
答案D
解析 根据题干中信息“trouble”，“U．S．agricultural workforce”可以定位至原文第三段第二句“As fewer such workers enter the country，the characteristics of the agricutural workforce are changing．”。定位段第三至第七句都在论证第二句的内容，其中第三句论证劳动的来源及其倾向，第五至第七句论证劳动力在变老并指出“And picking crops is hard on older bodies．”与选项D吻合。A项中的rising及illegal属于无中生有，B项中的high mobility与定位段中的“farm labors are more likely to be settled rather than immigrating”相矛盾，C项属于无中生有，均排除。故选D。
