 阅读理解When Richard Oswald was growing up in northwestern Missouri in the 1950s, his dad had a firm rule: Don't plant corn until mid-May. But that rule has become a relic of the past. In Rock Port, a small farming community near the Nebraska border, the growing season now begins more than a month earlier.That's not surprising. Across much of the US, winter is not as cold as it used to be. The four warmest Januaries on record have all occurred since 2016. In Missouri, winters are about 4 degrees hotter on average than in 1970-and farmers are starting to feel the effects.As the planet continues to warm, cold winter weather will become less common, said Amy Butler, a re-search scientist studying climate variability. "However, less cold does not mean never cold." Butler said. In the past decade, Liz Graznak's organic vegetable farm near Columbia, Missouri, has endured increasingly extreme swings in weather. "We don't get a couple of inches of snow; we get 18 inches of snow all at once and then in five days, it's 70 degrees again." Graznak said. "We don't get a couple of inches of rain; we get a 12-inch downpour in the span of 24 hours. That's devastating(毁灭性的)to a vegetable farm."To help protect her crops, Graznak has built four large greenhouses on her property in just over a decade. Inside, she's able to grow delicate, high-value crops, including flowers, lettuce and spinach.But these greenhouses come at a steep cost. Nearly seven years ago, Graznak spent more than $18,000 to build a greenhouse and since then, the price has more than doubled. "When I think about these costs, in my brain, I say, ‘OK, how many heads of lettuce is that?'" She said. "I know I can sell a head of lettuce for $4, so how many heads of lettuce do I have to sell to be able to pay for that greenhouse? And that's a lot of lettuce." （1） What does the author want to show by telling Richard Oswald's story? A . New farmers should learn to farm on their own. B .
