三、精读长难句（来自周四VOA金星材料）
第一句
New examinations of data collected from Venus suggest the planet is more volcanically active than previously thought.
结构分析：
· 主干：New examinations ... suggest ...（先找谓语 suggest）
· 过去分词后置定语：collected from Venus 修饰 data
· 宾语从句：suggest 后省略 that，内含比较级 more ... than previously thought（than 后省略 it was）
【翻译】对从金星收集的数据进行的新检验表明，这颗行星的火山活跃程度比此前认为的更高。
考研要点：过去分词作后置定语是考研阅读高频结构；suggest 此处意为“表明”，不跟虚拟语气。
第二句
The research team said the latest finding — combined with evidence from past studies — means the volcanic activity on Venus is likely comparable to Earth's.
结构分析：
· 主句 The research team said → 宾语从句（the latest finding ... means ...）
· 破折号之间 combined with ... 是插入的过去分词短语，阅读时先跳过抓主干
· Earth's 是 Earth's volcanic activity 的省略
【翻译】研究团队表示，这一最新发现结合过去研究的证据，意味着金星上的火山活动很可能与地球上的相当。
考研要点：破折号插入语先跳过；be comparable to 与……相当，写作可直接复用。
四、写作句型速记（来自周五实战日Day192）
现象—原因—建议三段式：现象段客观描述不表态 → 原因段2-3个论点用 The primary reason / Another factor 衔接 → 建议段具体到主体，结尾倒装提亮。

阅读理解（16-20）
Gold has always been seen as a precious metal and a safe haven in uncertain times. Experts estimate that over 200,000 tonnes of gold have been extracted from the earth so far. Gold became a form of money very early: archaeologists have found gold coins believed to date from the sixth century BC, because coins were far easier to carry and trade than bulky goods such as grain or animals. Today, beyond jewellery and other personal items, gold is bought and sold by investors and banks. Its price has always gone up and down, but in 2026 it reached its highest ever level. Wars, political uncertainty and purchases by central banks have all driven demand higher. When supply is limited and demand keeps rising, prices naturally climb.

A) Gold is the best investment for everyone.
B) Gold's value comes from its history, scarcity and rising demand.
C) Gold coins were invented in the sixth century BC.

17. According to experts, how much gold has been extracted from the earth?
A) Over 50,000 tonnes
B) Over 100,000 tonnes
C) Over 200,000 tonnes
D) Over 500,000 tonnes
18. Why did gold become a form of money early in history?
A) Because it was shiny and beautiful.
B) Because coins were easier to carry and trade than bulky goods.
C) Because governments forced people to use it.
D) Because gold never changes its shape.
19. The phrase "safe haven" in the passage is closest in meaning to:
A) a dangerous place
B) a secure choice in times of trouble
C) a type of bank account
D) a hidden mine
20. Which of the following is NOT mentioned as a factor driving gold demand?

七、学习建议
1. 词汇方面：本周45词横跨五大通用话题、黄金经济、太空探索、乡村振兴四大板块，建议用“话题串联法”把同组词编成一句话记忆，重点关注 supply / demand / evidence / livelihood 等写作高频词。
2. 语法方面：介词四大考点重点记“at/on/in时间点天段”和“across表面、through内部”两条规则；固定搭配 depend on / be aware of / access to 建议整体背诵。
3. 阅读方面：过去分词后置定语和破折号插入语先跳过抓主干，这两个长难句考点在考研阅读中反复出现。
4. 写作方面：“现象—原因—建议”三段式+7个万能句型建议默写一遍，Only in this way can we ... 是结尾提分利器。
