　　一、阅读理解。
　　第一节阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。
　　A
　　HasifaNakaziba, a mother of seven, has relied on farming corn and beans to support her family for years. But each year she would lose 30% of her harvest as pests affected her grain, taking their share of the food before it reached the dinner table.
　　“From nowhere rats, chickens and insects would come and eat it,” said Nakaziba, who lives in Nambale village, about 85 miles east of the capital, Kampala.
　　Like many farmers, Nakaziba, 47, lacked some drying equipment for the grain and so would dry it on the ground before storing, unaware that this could lead to deadly destruction (破坏) of the grain.
　　Her inability to safely store her harvest also forced her to sell her grain early, which meant Nakaziba received a very low price from the local market. “It affected our income, food safety and also the education of our children,” she says.
　　Then in 2014 Nakaziba’s life changed. She received training in post-harvest handling from the UN’s World Food Program(WFP), which started an operation designed to reduce post-harvest food losses for 16,600 low-income farmers in Uganda by providing them with simple storage (存储)equipment, such as granaries and grain storage bags. In a workshop, Nakaziba learned how to improve her farm management practices and buy new technology storage and handling equipment.
　　Today a huge granary, allowing Nakaziba to safely store more than 500 kg of grain for as long as she desires, for family eating or sale, sits in a corner of her modest home.
　　1. Why would Nakaziba’s harvest drop by 30% each year?
　　A. Because she received little education.
　　B. Because she sold her grain at a low price.

　　2. What does the underlined word “granaries” in paragraph 5 mean?
　　A. Places for laying equipment.
　　B. Large houses for storing grain.

　　3. What can we infer from the text?
　　A. Nakaziba benefits from training in post-harvest handling from the WFP.
　　B. Nakaziba prefers to dry grain on the ground before storage.
　　C. Nakaziba’s food safety depends on the high income.
　　D. Nakaziba sells her grain earlier than others every year.
