Global warming is already cutting substantially into potential crop yields in some countries—to such an extent that it may be a factor in the food price【C1】______ that have caused worldwide stress in recent years, researchers suggest in a new study.
Wheat yields in recent years were down by more than 10 percent in Russia and by a few percentage points【C2】______ in India, France and China compared with【C3】______ they probably would have been without rising【C4】______, according to the study.
Corn yields were【C5】______ a few percentage points in China, Brazil and France from what would have been【C6】______, said the researchers, whose findings were published in Friday’s【C7】______ of the journal Science.
Some countries saw small gains from the temperature increases, however. And in all countries, the【C8】______ carbon dioxide that humans are【C9】______ into the air acted as a【C10】______ that encouraged plant growth,【C11】______ some of the losses from rising temperatures caused by that same greenhouse gas.
【C12】______, the study’s authors found that when the gains in some countries were weighed【C13】______ the losses in other countries, the overall global【C14】______ of climate change has been small so far: losses of a few percentage points for wheat and corn from what they would have been【C15】______ climate change. The general impact on production of rice and soybeans was【C16】______, with gains in some regions entirely counterbalancing losses in others.
【C17】______ the authors of the study pointed out that temperature increases were expected to【C18】______ in coming decades, making it likely that the challenges【C19】______ food production will grow in a era when demand is expected to【C20】_____ sharply. [br] 【C6】
选项
A、assumed
B、thought
C、guessed
D、expected
答案
D
解析
语义线索题。根据第一段第一句话的提示,粮食产量低于预期,而第三段第一句话是其中一个例证,所以此处要填一个过去分词,表示预期产量,故选expected“预料,预计,期待”。assumed“假定,假设”和guessed“猜测”可排除,因为人们对于玉米产量应该是进行预估,而不是进行假设或猜测。thought“思考,想”,不符合句意。
