1、Unit 2 Working the land(建议用时：35分钟).阅读理解A(2023年沈阳高三质监)China is a large producer and consumer of rice. But, as a result of climate change, the amount of land available for rice growing in the country is shrinking. The concern has motivated scientists led by Yuan Longping，known as “the father of hybrid
2、 rice”， to look for new ways of growing the grain.Now theyre celebrating successful efforts to grow ricein sand and seawater. Rice is traditionally grown in soil and fresh water. Starting from January, according to the official Xinhua News Agency, the scientists have grown dozens of varieties of ric
3、e in the deserts of Dubai. They experimented with seawater because it is easier to obtain in the desert than fresh water.China is not the only country facing the issue of overly salty soil. Around the world, there are around 2.35 billion acres of highly saline(含盐的) land. And the number is increasing
4、 because of rising sea levels and climate change.“Probably only a small part of the worlds saline land could be brought into production with seawater rice，but that would still have a very important effect on food security，” Even R. Pay, a senior analyst, said.Yuan told Xinhua that one of the varieti
5、es of rice grown in Dubai produced over three tons, per acre, which Yuan said was beyond expectations.Rice is the basic food in many parts of the world. About 90% of rice consumption is from Asia, but demand in Africa and Latin America is on the rise.A climate change researcher said the successful e
6、xperiment could potentially benefit many countries. “This is a fantastic development, which is likely to have a good effect on agricultural resource and waterpoor countries, particularly in North Africa region.”Even though the cost of growing salttolerant rice is still high，it will also have strateg

If the new results are confirmed, promoting organic food consumption could be a promising preventative strategy against diseases, a team of researchers from several French institutions said.Among the environmental risks for cancer
13、, there are growing concerns about exposure to different types of pesticides(杀虫剂) from farming. The impact of such chemicals on the human body is still not well understood, but there are some indications that harmful effects can occur even at low concentrations.Meanwhile, pushed by environment and h
14、ealth concerns, the organic food market continues to grow rapidly. Organic food is produced without the use of synthetic(合成的) fertilizers, pesticides, genetically modified organisms and veterinary(兽医的) medications.“Organic foods are less likely to contain pesticide remains than conventional foods, a
15、nd studies have shown that an organic diet reduces exposure to certain pesticides，” Julia Baudry, lead author of the study from the Centre of Research in Epidemiology(流行病学) and Statistics in France, told Newsweek.“In the general population, the primary route of exposure is the diet, especially intak

However, few studies have examined the association between organic food consumption and cancer risk.”For the study, published in the journal JAMA Internal Medicine, a team of researchers examined data on the organic food consumption frequency and dietary intake of 68，946 French adults collected by an ongoing s
