题目

阅读理解 Industrial agriculture is often held up as the solution to feeding the world's growing population. But small farms of about 25 acres or less produce over 70 percent of the world's food. To raise awareness of the contribution of these farmers, a global photo exhibition, We Feed the World, is to open on October 12 in London. "Industrial agriculture, which mainly focuses on a few types of crops, is not the only answer," says art director Francesca Price. "We want these images to empower people to support their local food system." By growing traditional and non-commercial varieties, small farms support biodiversity and increase food security. With only 12 plants and five animal species making up 75 percent of what the world eats, food systems will be easily hurt by natural disasters and disease outbreaks. However, traditional farming communities are working to preserve their ancient seed diversity. Keeping variety alive is very important in the face of climate change. In the future, researchers might need to get particular genes from one variety to help another to adapt to warmer, stormier, or drier weather, or to save a prized variety from disease. Contrary to the false impression held by the public, small farms that practise traditional agriculture can be highly productive. Studies show that the output of crops rises when there's a wider diversity of crops being grown on a farm, and money is saved since the need for harmful fertilizer and other chemicals is reduced. "The photographs of family farmers may tell just a few local stories, but the message is universal," says photographer Cheryl Newman. "I hope that the images will leave viewers thinking deeply about where their food comes from and the impact it has on the world around us." （1） What is the purpose of the photo exhibition? A .

It is the only way to feed the world's population. （3） Why is it important to preserve the traditional and non-commercial crops? A . Their genes are much better. B . Their output is much higher. C . They don't need chemical fertilizers at all. D . They may help improve the other crops. （4） What is the text mainly about? A . The importance of traditional small farms. B . The problems with the industrial agriculture. C . The consequences of fast-growing population. D . The impact of climate change on agriculture. 答案： C B D A
