48. What do we learn about “Project Neurice”?
- A. Its goals will have to be realized at a cost.
- B. It aims to increase the yield of Spanish rice.
- C. Its immediate priority is to bring the pest under control.
- D. It tries to kill the snails with the help of climate change.
答案：C
答案句：“The project has two sides,” says Xavier Serrat, Neurice project manager and researcher at the University of Barcelona. “The short-term fight against the snail, and a mid- to long-term fight against climate change. But the snail has given the project greater urgency.”
参考译文：“该项目有两个方面，”巴塞罗那大学Neurice项目经理兼研究员Xavier Serrat说。“短期对抗蜗牛，中期到长期对抗气候变化。但蜗牛让该项目更加紧迫。”
定位线索：题干“Project Neurice”→答案句取自第4段“The project has two sides”；文中“short-term fight against the snail”对应选项C“immediate priority is to bring the pest under control”；文中“greater urgency”对应选项C“immediate priority”。
解析：细节题。答案句明确说项目短期目标是“fight against the snail”，且蜗牛让项目“greater urgency”，对应选项C“Its immediate priority is to bring the pest under control”。选项A“at a cost”原文未提；选项B“increase the yield”偷换概念，原文是抗盐而非增产；选项D“with the help of climate change”与原文矛盾，蜗牛是敌人而非工具。
50. What is the ultimate goal of the EU-funded program?
- A. Cultivating ideal salt-resistant rice varieties.
- B. Increasing the absorbency of the Spanish rice.
- C. Introducing Spanish rice to the rest of Europe.
- D. Popularizing the rice crossbreeding technology.
答案：A
答案句：As an EU-funded effort, the search for salt-tolerant varieties of rice is taking place in all three countries. Each team is crossbreeding a local European short-grain rice with a long-grain Asian variety that carries the salt-resistant gene. The scientists are breeding successive generations to arrive at varieties that incorporate salt tolerance but retain about 97 percent of the European rice genome (基因组).
参考译文：作为欧盟资助的项目，寻找耐盐水稻品种的工作正在这三个国家进行。每个团队都在将当地欧洲短粒水稻与携带耐盐基因的亚洲长粒水稻品种杂交。科学家们正在培育连续几代，以获得兼具耐盐性但保留约97%欧洲水稻基因组的品种。
定位线索：题干“ultimate goal”→答案句取自末段“the search for salt-tolerant varieties of rice”；文中“arrive at varieties that incorporate salt tolerance”对应选项A“Cultivating ideal salt-resistant rice varieties”；文中“retain about 97 percent of the European rice genome”对应选项A“ideal”。
解析：细节题。末段明确指出欧盟资助项目的目标是“search for salt-tolerant varieties of rice”，并通过杂交“arrive at varieties that incorporate salt tolerance”，对应选项A“Cultivating ideal salt-resistant rice varieties”。选项B“increasing the absorbency”是第3段提到的目标之一，但非终极目标；选项C“introducing Spanish rice to the rest of Europe”无中生有；选项D“popularizing the crossbreeding technology”偷换概念，原文是培育品种而非推广技术。
