第二节 (共 10 小题;每小题 1.5 分,满分 15 分) 阅读下面短文,在空白处填入 1 个适当的单词或括号内单词的正确形式。 It’s time to reconsider food. Around the globe, food problems threaten wildlife, wild places and the planet itself. Today, 7.3 billion people consume 1.6 times () the earth’s natural resources can supply. By 2050, the world’s population () (reach) 9 billion and the demand for food will double. So how do we produce more food for more people without () (expand) the land and water already in use? We can’t double the amount of food. () (fortunate), we don’t have to — we just have to double the amount of food available now instead. () short, we must freeze the footprint of food. In the near-term, food production is enough to provide for all, but it doesn’t reach everyone who needs it. About 1.3 billion tons of food () (waste) each year — four times the amount () (need) to feed the more than 800+ million people who are () (hunger). By improving efficiency and productivity while reducing waste and shifting consumption () (pattern), we can produce enough food for everyone by 2050 on roughly () same amount of land we use now.
