第三部分 阅读理解(共15小题;每小题2分,满分30分)
请认真阅读下列短文,从短文后各题所给的A、B、C、D四个选项中,选出最佳选项,并在答题纸上将该项涂黑。
John Davis doesn’t use his GPS system in
his car. Instead of guiding the direction, the Delaware farmer uses it to
determine where and how much fertilizer to use on the crops on his 4,000-acre
family-owned farm. Technological advances like that last year helped Davis and
other Ohio farmers set a record for corn product. Ohio's corn crop in 2009
totaled 546 million bushels(蒲式耳), despite a cooler and wetter than normal spring, a dry summer and
a delayed, wet harvest. Davis said. “I knew it would be a good crop, but it was
much better than we expected.”
A farmer can map his fields on GPS,
spotting where soil turned out to be least fertile(肥沃的) and using more fertilizer
the next year in those areas where corn didn’t grow as well.
Although Ohio farmers produced more corn,
it was grown on less land than in past years. Total area used for corn in Ohio
was 3.35 million acres, about the same as in 2008 but down from 3.85 million
acres in 2007, said Dwayne Siekman, director of the Ohio Corn Growers
Association. “When you look at the total number of acres in Ohio used for corn,
it’s clear that farmers are able to do more with less,” he said. “American
farmers can grow five times more corn on 20 percent less land than they did in
the 1930s, saying that modern farming techniques are necessary for a growing
demand in the world today.” That technology includes using improved seeds that
can withstand(忍受)
greater temperature extremes and pests, Siekman said.
Farmers aren't the only ones who benefit.
Consumers(消费者) do,
too, as food costs reduce in the face of “enough supplies of corn,” said Fred
Yoder, who runs a 1,500-acre corn, soybean and wheat farm in Plain City. “This
is the best, highest-producing corn crop that I've raised in 30 years,” he
said.
