2021考研英语二阅读理解 Text 2 原文
With the global population predicted to hit close to 10 billion by 2050, and forecasts that agricultural production in some regions will need to nearly double to keep pace, food security is increasingly making headlines. In the UK, it has become a big talking point recently too, for a rather particular reason: Brexit.
Brexit is seen by some as an opportunity to reverse a recent trend towards the UK importing food. The country produces only about 60 per cent of the food it eats, down from almost three-quarters in the late 1980s.A move back to self-sufficiency , the argument goes, would boost the farming industry, political sovereignty and even the nation’s health. Sounds great — but how feasible is this vision?
According to a report on UK food production from the University of Leeds, UK, 85 per cent of the country’s total land area is associated with meat and dairy production. That supplies 80 per cent of what is consumed, so even covering the whole country in livestock farms wouldn’t allow us to cover all our meat and dairy needs.
There are many caveats to those figures, but they are still grave. To become much more self-sufficient, the UK would need to drastically reduce its consumption of animal foods, and probably also farm more intensively — meaning fewer green fields and more factory-style production.
But switching to a mainly plant-based diet wouldn’t help. There is a good reason why the UK is dominated by animal husbandry: most of its terrain doesn’t have the right soil or climate to grow crops on a commercial basis. Just 25 per cent of the country’s land is suitable for crop-growing, most of which is already occupied by arable fields. Even if we converted all the suitable land to fields of fruit and veg — which would involve taking out all the nature reserves and removing thousands of people from their homes — we would achieve only a 30 per cent boost in crop production.
Just 23 per cent of the fruit and vegetables consumed in the UK are currently home-grown, so even with the most extreme measures we could meet only 30 per cent of our fresh produce needs. That is before we look for the space to grow the grains, sugars, seeds and oils that provide us with the vast bulk of our current calorie intake.

26Some people argue that food self-sufficiency in the UK would ______.
答案B
解析原文写明“a move back to self-sufficiency, the argument goes, would boost the farming industry, political sovereignty and even the nation’s health”，即有人认为自给能增进产业、主权乃至国民健康，与B中“contribute to the nation’s well-being”对应。A把全球人口增长误当成英国自给的障碍；C政府优先未见；D与“boost the farming industry”相反。

27The report by the University of Leeds showed that in the UK ______.
答案C
解析利兹大学报告指出“85 per cent of the country’s total land area is associated with meat and dairy production”，直接对应C：大部分土地用于肉奶生产。A未说土地利用低效；B工厂化生产是后文推演的可能代价，非报告结论；D把农田改成更多绿地与原文方向不符。

28Crop-growing in the UK is restricted due to ______.
答案C
解析限制作物种植的原因是“most of its terrain doesn’t have the right soil or climate…Just 25 per cent of the country’s land is suitable for crop-growing”，即土壤气候等自然条件，故选C。A技术、B饮食传统、D商业利益均非该段所述的限制因素。
-
29It can be learned from the last paragraph that British people ______.
答案A
解析末段“Just 23 per cent of the fruit and vegetables consumed in the UK are currently home-grown”，说明鲜果蔬绝大部分依赖进口，对应A。B消费稳步上升、C设法减热量、D培育新粮食品种文中均未提及。

30The author's attitude to food self-efficiency in the UK is ______.
答案B
解析作者先说“Sounds great — but how feasible is this vision?”，继而指出即便全改畜牧仍难满足肉奶、改种作物也仅能小幅增产，整体质疑可行性，态度为doubtful（B）。A辩护、C容忍、D乐观均与不断列举“grave”限制不符。
