People from all over the world settle in its colourful neighbourhoods, each bringing unique food, music, and traditions. I must admit that when I first visited Chinatown and the Mission District, it never occurred to me that so many cultures could coexist in one city. Many immigrants came here to seek better opportunities and build new lives. Some claim that the city's energy comes from this mix of backgrounds. However, life is not always easy — newcomers often feel the need to escape loneliness by finding communities that share their language and customs. Walking through the historical streets, you can see how each wave of immigrants has left its mark. The city's financial growth owes much to the entrepreneurial spirit of these communities. Local organisations carefully select events and festivals that celebrate this rich cultural mix. It is hard to admit that sometimes misunderstandings occur, but most residents agree that the benefits far outweigh the challenges. Those who seek a place where they can truly belong often find it here. As one resident put it, "I came to escape the ordinary — instead I found something extraordinary." Nowadays, researchers claim that diverse cities are more creative and innovative. Every year, new families settle here, adding their own stories to the city's never-ending tale. This historical journey of cultures reminds us that the whole world can feel like home if we know where to look. 【中文译文】 旧金山是美国最具多样性（diverse）的城市之一。来自世界各地的人们在它多彩的社区定居（settle），每个人都带来了独特的食物、音乐和传统。我必须承认（admit），当我第一次参观唐人街和米慎区时，我从未想到（occur）过这么多文化可以共存于一个城市。许多移民来这里寻找（seek）更好的机会，建立新的生活。一些人声称（claim）这座城市的活力正是来自这种背景的融合。然而，生活并不总是容易的——新来者常常需要逃避（escape）孤独，通过寻找与他们有共同语言和习俗的社区。 穿过历史（historical）悠久的街道，你可以看到每一次移民浪潮如何留下了印记。这座城市的金融（financial）发展很大程度上归功于这些社区的创业精神。当地组织精心挑选（select）庆祝这种丰富文化融合的活动和节日。我们不得不承认（admit）有时误解确实会发生（occur），但大多数居民都认为好处远远大于挑战。那些寻找（seek）一个真正归属之地的人往往在这里找到它。正如一位居民所说："我来逃避（escape）平庸——结果我发现了非凡。"如今，研究人员声称（claim）多样性城市更具创造力和创新力。每年都有新的家庭在这里定居（settle），为这座城市永不完结的故事增添他们自己的篇章。这段历史（historical）文化之旅提醒我们，只要知道去哪里寻找，整个世界都可以像家一样。

These cities claim their strength from the mix of cultures, languages, and traditions that their residents bring. Urban planners now admit that cultural diversity is not just a social ideal but an economic necessity. When people from different backgrounds settle in the same neighbourhood, they bring financial energy and creative ideas that benefit everyone. However, this does not mean that challenges disappear — misunderstandings can occur when cultures clash, and some newcomers feel the urge to escape back into communities where everyone shares their background. A study conducted by researchers at the University of California claims that immigrants who actively engage with different cultures show higher levels of creativity and problem-solving skills. "We did not expect the effects to be so significant," admitted Dr. Maria Gonzalez, the lead researcher. "People who seek out cross-cultural experiences tend to become more open-minded and adaptable." The researchers carefully selected 800 participants from 15 different ethnic backgrounds for the five-year study. It never occurred to them that language barriers would be less of a problem than they had assumed — most participants found creative ways to communicate. The historical roots of multicultural cities are also worth noting. Take San Francisco as an example. During the Gold Rush, people from China, Italy, Ireland, and many other countries came to seek their fortune. This wave of immigration shaped the city's identity and created the vibrant neighbourhoods we see today. The financial contributions of these immigrant communities have been enormous — from small family-owned restaurants to major technology companies. Nevertheless, the city also faces serious challenges. Housing costs have forced many long-term residents to escape to cheaper areas, threatening the very diversity that made the city special in the first place. So what can we learn from these cities? The answer seems clear: cultural diversity is not something to be merely tolerated — it should be actively celebrated and protected. As one community leader in the Mission District said, "When I first arrived, I wanted to escape the feeling of being an outsider. But once I learned to embrace the diversity around me, I found a sense of belonging I had never experienced before." Cities that understand this will be the ones that thrive in the decades to come. 1. What is the main idea of the passage? A. San Francisco has the most diverse population in the world. B. Cultural diversity brings both challenges and significant benefits to cities. C. Immigrants should try to escape from diverse communities to avoid conflicts. D. Technology companies have replaced small family-owned restaurants in diverse cities. 2. According to Dr. Maria Gonzalez, what unexpected finding did the study reveal? A. Language barriers were the most difficult challenge for participants to overcome. B. Most participants chose to leave diverse communities within the first year of the study. C. Cross-cultural experiences significantly improve creativity and problem-solving skills. D. Participants from similar backgrounds showed the highest levels of adaptability. 3. How did the Gold Rush contribute to San Francisco's development? A. It limited the city's growth to only a few major industries. B. It reduced the number of immigrants coming to the city in later decades. C. It forced the government to close down Chinatown and the Mission District. D. It attracted immigrants from various countries, creating a multicultural identity. 4. What can be inferred from the last paragraph? A. Cultural diversity should be actively protected rather than just tolerated. B. Most immigrants eventually decide to return to their home countries. C. The feeling of being an outsider is impossible for immigrants to overcome. D. Housing costs no longer affect the diversity of modern multicultural cities. 【参考答案】 1. B 2. C 3. D 4. A 【解析】 1. B 本题考查主旨大意。全文围绕文化多样性给城市带来的挑战与益处展开论述。第一段提出多样性是经济必需品，但也存在文化冲突；第二段通过加州大学研究说明多样性对创造力的促进作用；第三段以旧金山为例介绍多元文化的历史根源和现实挑战；第四段总结应积极保护和庆祝多样性。A项"旧金山人口最多样化"不是全文主旨；C项主张逃避多样性社区，与全文主旨相反；D项说科技公司已取代小型餐馆，全文未提及。 2. C 本题考查细节理解。由第二段 Dr. Maria Gonzalez 的话"We did not expect the effects to be so significant"以及后文"People who seek out cross-cultural experiences tend to become more open-minded and adaptable"可知，研究的意外发现是跨文化体验显著促进了创造力和问题解决能力。A项"语言障碍最困难"与原文"It never occurred to them that language barriers would be less of a problem"相反；B项说参与者离开多样性社区，与原文不符；D项原文未提及相似背景的人适应力最强。 3. D 本题考查细节理解。由第三段"During the Gold Rush, people from China, Italy, Ireland, and many other countries came to seek their fortune"以及"This wave of immigration shaped the city's identity"可知，淘金热吸引了各国移民来旧金山，形成了多元文化身份。A项说限制增长、B项说减少移民、C项说政府关闭唐人街，均与原文完全相反或未提及。 4. A 本题考查推理判断。由最后一段"cultural diversity is not something to be merely tolerated — it should be actively celebrated and protected"以及移民的话"once I learned to embrace the diversity around me, I found a sense of belonging"可推知，文化多样性应被积极保护而非仅仅容忍。B项说移民最终回国，原文未提及；C项说外来感无法克服，与原文相反；D项说住房成本不再影响多样性，与原文"forced many long-term residents to escape to cheaper areas"相反。 Part 8 复现知识点 — 英译汉 请根据英文写出对应汉语释义： 乐思英语 ·高考高频知识点 1 学科网（北京）股份有限公司 1. diverse — __________ 2. admit — __________ 3. occur — __________ 4. claim — __________ 5. seek — __________ 6. escape — __________ 7. settle — __________ 8. financial — __________ 9. historical — __________ 10. select — __________ 11. diversity — __________ 12. admission — __________ 13. occurrence — __________ 14. settlement — __________ 15. seek one's fortune — __________ 16. escape from — __________ 17. settle down — __________ 18. historic — __________ 19. selection — __________ 20. finance (v.) — __________ 【参考答案】 1. 不同的；多样的 2. 承认；准许进入 3. 发生；想到 4. 声称；要求 5. 寻找；寻求 6. 逃跑；逃避 / 逃避现实的方式（n.） 7. 定居；解决；安顿 8. 财政的；金融的 9. 历史的 10. 选择；挑选 11. 多样性（名词） 12. 承认；准许进入（名词） 13. 事件；发生（名词） 14. 定居点；解决（名词） 15. 寻找出路；碰运气 16. 从…逃跑 17. 定居；平静下来 18. 有历史意义的（形容词） 19. 选择；挑选（名词） 20. 为…提供资金 Part 9 写作运用 — 词汇升级 同义转换：用本专题词汇替换下面句中的普通词，提升写作表达： 1.
