“You are going to enter the largest wild seed bank in the world,” said Sharon Balding. She is the Seed Collections manager at the Millennium Seed Bank(MSB). This seed bank is in Sussex, UK. “Inside there are over 39,000 different kinds of seeds from more than 100 countries. That’s over 2.8 billion seeds,” Sharon said. She turned a key, and the heavy door slowly opened.
Inside the MSB, there are many glass bottles with seeds. The bottles are named with numbers, not plant names. “This is for safety,” Sharon said. “If someone takes the seeds away, he won’t know what they are!” So, is the collection worth a lot of money? “It’s invaluable,” said Sharon. “Our future life rests on these seeds. Without them, we could lose important things, like food and medicines.”
Some seeds here have already helped. For example, in early 2020, fires in Australia burned down the natural environment of a special plant. The MSB sent 250 seeds back to the country to help the plant reestablish itself in the wild again.
As the world gets warmer because of climate change, it will be harder for some plants to live in the UK. “One day it may be too warm for some of the UK’s trees to grow,” said Owen Blake. He is part of the UK Tree Seed Collecting Team. “So we are looking for and studying trees from other parts of the world. Some of these trees can grow in the warmer UK climate,” he said.

答案：Ⅲ. 本文介绍了世界上最大的野生种子库MSB，其保存的种子对人类未来生存发展至关重要，可用于重建被破坏的生态系统以及应对气候变化对英国本土植物的威胁。
1－5 DACDA
1－5 DACDA
解析：
【分析】首先通读全文，明确文章围绕世界最大野生种子库MSB展开，介绍其规模、种子命名原因、种子的生态作用及应对气候变化的举措。针对每道题，需精准定位原文对应内容，逐一比对选项排除错误答案：第1题定位第一段关于MSB的描述；第2题定位第二段种子命名的原因；第3题定位第三段澳大利亚火灾后送种子的语境猜测词义；第4题定位第四段Owen的工作内容；第5题归纳全文核心主旨。
【解析】1. 细节理解题：定位第一段第一句可知MSB是世界最大野生种子库，A项“仅来自英国”与原文“来自100多个国家”不符；B项“少于28亿颗”与原文“超28亿颗”不符；C项“超39万种”与原文“超3.9万种”不符，故选D。2. 细节理解题：定位第二段“这是为了安全，防止有人拿走种子后不知道是什么”，即保护种子，故选A。3. 词义猜测题：澳大利亚火灾烧毁植物生存环境，MSB送种子回去帮助植物重新建立生存环境，reestablish意为“重新生长、重建”，对应C项“Grow back”。4. 细节理解题：定位第四段Owen提到“寻找并研究能适应英国更暖气候的其他地区树木”，故选D。5. 主旨大意题：全文强调MSB的种子对人类未来生存（应对生态危机、气候变化）的重要性，A项“为更安全的未来储备种子”契合主旨；B项“气候变化解决方案”范围过宽；C项“种子库之旅”片面；D项“英国树种子收集团队科学家”片面，故选A。
【答案】1－5 DACDA
【知识点】：阅读理解（细节理解、词义猜测、主旨大意）
【点评】：本文是介绍野生种子库的说明文，考查学生快速定位原文信息、猜测词义及归纳主旨的能力，题目难度适中，需仔细比对原文与选项，避免细节误解。
【难度系数】：0.7
