“You are about 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 located in Sussex, the UK. “Inside there are more than 40,000 different species of seeds from more than 100 countries,” Sharon said. She turned a key, and the heavy vault(保险库) door slowly opened.
The MSB vaults are guarded 24 hours a day. Inside, rows of glass jars hold the seeds. The jars are labelled with numbers, not plant names. “This is for security,” Sharon said. “If the seeds were stolen, the thief would not know what they were!” So is the collection worth a lot of money? “It's priceless,” said Sharon.
Collections there are dried and frozen, preserved for the future. They provide an insurance policy against the threats plants face in the wild. Once stored in the Millennium Seed Bank, they act as resources used for research in finding sustainable solutions to global challenges. “Our future survival depends on these seeds. Without them, we could lose important things, like food and medicines,” Sharon said.
Some of the seeds here have already been used. In early 2020, for example, wildfires in Australia burned down the habitat of a rare plant. The MSB sent 250 seeds to help it grow back in the wild.
Sadly, today, two out of five plant species are at risk of extinction. And as the world gets warmer because of climate change, it will be harder for some plants to survive. “We are looking for and studying trees from other parts of the world,” said Owen Blake. He is part of the UK Tree Seed Collecting Team. “Some of these trees will be able to grow in the UK's warmer climate,” he said. These scientists are working hard to solve our planet's problems!
()1. 新考法·行文方式 How does the writer start the text?
A. By giving a fact. B. By asking a question.
C. By telling a story. D. By using a saying.
()2. From Paragraph 2 we can know that .
A. we can find some plant names on the jars
B. the prices of the plants are on the jars
C. we can see the number of the plant on the jar
D. the guards can tell you the name of the plant
()3. The underlined word “them” here refers to “”.
A. the threats B. the seeds C. global challenges D. plant numbers
()4. 新考法·篇章结构 Which is the RIGHT structure of the passage? (①=Paragraph 1...)
A. ①/②③④/⑤ B. ①②/③④/⑤ C. ①②③/④⑤ D. ①/②③/④⑤

1. A 行文方式题。由第一段内容可判断，作者陈述了MSB的位置、里面储存的种子数量等，也就是陈述了一个事实。
2. C 细节理解题。由第二段中“The jars are labelled with numbers, not plant names.”可知，罐子上标有编号，而不是植物名称。
3. B 代词指代题。由句子“Our future survival depends on these seeds.”可知，我们未来的生存取决于这些种子。没有这些种子，我们可能会失去重要的东西。所以them指代“种子”。
4. B 篇章结构题。由全文内容可知，第一、二段对野生种子库MSB进行描述；第三、四段表明库里种子的状况及用途；第五段说明植物物种面临灭绝的风险。

【分析】
1. 第1题（行文方式）：需分析作者开篇的写作手法，第一段直接陈述世界最大野生种子库MSB的位置、储存种子数量等客观事实，属于陈述事实，对应选项A。
2. 第2题（细节理解）：定位第二段关于罐子标签的描述，找到关键句“jars are labelled with numbers, not plant names”，对比选项排除错误项，确定C正确。
3. 第3题（代词指代）：代词通常指代前文出现的名词，根据前一句“Our future survival depends on these seeds”，可知them指代前文的seeds，选B。
4. 第4题（篇章结构）：划分段落功能，①②段介绍MSB基本情况，③④段讲种子的保存与用途，⑤段讲植物灭绝风险，对应结构①②/③④/⑤，选B。
【解析】
1. 本题考查行文方式。第一段作者直接陈述了世界最大野生种子库MSB的位置、储存种子的数量等客观事实，属于陈述事实，因此选A。
2. 本题考查细节理解。根据第二段“The jars are labelled with numbers, not plant names.”可知，罐子上标注的是数字而非植物名称，A、B、D项均与原文不符，C项正确。
3. 本题考查代词指代。代词通常指代前文出现的名词，前一句提到“Our future survival depends on these seeds”，后一句“Without them”中的them指代前文的seeds，因此选B。
4. 本题考查篇章结构。通读全文，第①②段介绍MSB的基本情况（位置、保险库、罐子标签等）；第③④段说明种子的保存方式、用途；第⑤段阐述植物面临的灭绝风险及科学家的应对措施，因此结构为①②/③④/⑤，选B。
