This period is short in topics and wide in scope, and the exam treats it as the culmination of the whole course.
这一时期话题不多，但涵盖极广， 考试把它当作整门课程的收束。
Three arguments that have run since the founding come due here: how big government should be, what the country's global role is, and who counts as a full member of the nation.
三场自建国以来贯穿始终的争论 在这里到期结算： 政府应该有多大， 国家在世界上扮演什么角色， 以及谁算得上是这个国家的完整成员。
If you can name which of those three a question is really about, you can answer it with evidence from any period on the course.
如果你能说出一道题 真正问的是这三者中的哪一个， 你就能用课程中任何时期的证据来作答。
The conservative movement that organised in the 1960s and 1970s came to power with Ronald Reagan, and its programme had three strands.
在六七十年代组织起来的保守主义运动 随里根上台执政， 它的纲领有三条主线。
Tax cuts and deregulation, on the argument that reducing the burden on business would raise growth — supply-side economics.
减税与放松管制， 理由是减轻企业负担能提高增长， 也就是供给学派经济学。
Reduced federal spending on domestic programmes, although defence spending rose sharply and deficits grew.
削减国内项目的联邦支出， 不过国防开支大幅上升，赤字扩大。
And appeals to social conservatism, on religion, family, and law and order.
以及诉诸社会保守主义， 围绕宗教、家庭与法律秩序。
State supply-side as an argument and then state what followed, because an evaluation needs both.
要把供给学派作为一种论证来陈述， 再说明随后发生了什么， 因为评价题两者都需要。
The lasting result is a shift in the terms of debate: after 1980 both parties argued within narrower limits about the federal government's economic role than at any time since the New Deal.
持久的结果是辩论范围本身的移动： 1980 年之后，两党在联邦政府经济角色上的争论范围， 比新政以来任何时候都更窄。
Renewed military build-up, negotiation, and above all internal weakness in the Soviet Union brought the Cold War to an end, and the Soviet system collapsed between 1989 and 1991.
重新展开的军备建设、谈判， 以及最重要的苏联内部的虚弱， 使冷战走向终结， 苏联体制在 1989 至 1991 年间崩溃。
Do not stop at the ending.
不要停在"结束"这里。
The mark is in what it opened: the United States became the sole superpower, with unresolved questions about when and where to intervene, and about what commitments made sense once containment no longer organised policy.
得分点在于它打开了什么： 美国成为唯一的超级大国， 而何时、在何处进行干预的问题悬而未决， 一旦遏制不再统摄政策， 哪些承诺才说得通也悬而未决。
Every foreign-policy argument after 1991 sits in that gap.
1991 年之后的每一场外交政策争论， 都落在这个空隙里。
Three forces reshaped the economy after 1980, and the tip is to keep them distinct rather than blurring them into "the economy changed".
1980 年之后有三股力量重塑了经济， 提示是把它们区分开， 不要含糊成"经济变了"。
Globalization: trade agreements, integrated supply chains, and competition that moved manufacturing abroad.
全球化：贸易协定、一体化的供应链， 以及把制造业推向海外的竞争。
Deindustrialization: the loss of manufacturing employment in older industrial regions and the growth of service work.
去工业化：老工业区制造业就业的流失， 以及服务业工作的增长。
Technological change: computing and then the internet, transforming productivity, work and communication.
技术变革：计算机，然后是互联网， 改变了生产率、工作与沟通方式。
Together they raised aggregate wealth while widening income inequality and reducing security for workers whose industries declined.
三者共同抬高了总体财富， 同时扩大了收入不平等， 并削弱了衰退行业工人的保障。
That combination is the economic argument that has dominated politics ever since.
这一组合正是此后主导政治的经济论证。
Migration in the 1990s and 2000s continued to reshape the population, with growth in arrivals from Latin America and Asia following the 1965 reform of immigration law.
九十年代与两千年代的人口迁移 继续重塑着人口结构， 随着 1965 年移民法改革， 来自拉丁美洲与亚洲的移民增长。
Name that shift in origins, then move to the consequences, because the consequences are the examinable part: population growth in the South and West, multi-ethnic cities, ongoing debate over immigration policy and border enforcement, and continuing arguments about citizenship and national identity.
先说出这一来源的转变， 再谈后果， 因为后果才是考点： 南部与西部的人口增长、 多族裔城市、 围绕移民政策与边境执法的持续争论， 以及关于公民身份与国家认同的持续争议。
That last one is the same argument the course has traced since Reconstruction.
最后这一项， 正是这门课程自重建以来 一直在追踪的同一场争论。
The challenges of the twenty-first century group into a few kinds.
二十一世纪的挑战可以归成几类。
The later topics group around a small number of developments.
后面的主题围绕少数几项发展。
The September 11 attacks and the response: military intervention abroad, a new security apparatus, and renewed debate over the balance between security and civil liberties.
九一一袭击及其回应： 海外军事干预、 新的安全体制， 以及关于安全与公民自由之间平衡的重新争论。
Recognise that tension.
要认出这一张力。
It is the same one as the Red Scare and as the First World War, and saying so is worth a mark.
它与红色恐慌、与第一次世界大战时的张力是同一个， 说出这一点就能得分。
Then economic crisis in 2008 and the argument over government's role in stabilising the economy; political polarisation, amplified by changes in media; and debate over climate and energy policy.
接着是 2008 年的经济危机， 以及关于政府在稳定经济中角色的争论； 被媒体变化放大的政治极化； 以及关于气候与能源政策的辩论。
The period's reasoning skill is causation, and the most useful move on a long-span prompt is to link a recent development back to an earlier one.
本时期的推理技能是因果， 而在跨时段题目上最有用的一招， 是把近期的发展与更早的发展连接起来。
Deindustrialisation connects to the market revolution's regional specialisation.
去工业化连到市场革命的区域专业化。
Immigration debates connect to the nativism of the 1850s and the 1920s.
移民争论连到 1850 年代与 1920 年代的排外主义。
Arguments over federal power connect to the New Deal.
关于联邦权力的争论连到新政。
Each of those pairs lets you use evidence from two periods in one sentence, and saying what continued is what turns that sentence into causation rather than coincidence.
每一组配对 都让你在一个句子里用上两个时期的证据， 而说明什么在延续， 正是把这个句子从巧合变成因果的关键。
The 2026 exam asked you to evaluate the extent to which women's participation in public life in the United States changed over the twentieth century.
二〇二六的考试要你评价 二十世纪美国女性参与公共生活 在多大程度上发生了变化。
Pause and try a thesis.
先暂停，试写一个论点。
Step one: distinguish kinds of change and their timing.
第一步：分清变化的种类与时间。
Step two: name suffrage, wartime employment and the women's movement.
第二步：点出选举权、战时就业与妇女运动。
Step three: occupational segregation and unequal pay meant participation expanded faster in law than in economic power.
第三步：职业隔离与同工不同酬 意味着参与在法律上扩展得比对经济权力更快。
A long-span prompt wants what kind of change and where it stalled.
跨时段题目要的是哪一种变化，以及它在哪里停住。
Five things to carry out.
带走五件事。
First, supply-side is an argument, and the deficits that followed belong in the evaluation.
第一，供给学派是一种论证， 随后的赤字属于评价的一部分。
Second, the Cold War's end matters for what it opened.
第二，冷战结束的意义在于它打开了什么。
Third, globalization, deindustrialization and technological change are three causes, not one.
第三，全球化、去工业化与技术变革 是三个原因，不是一个。
Fourth, after 1965 name the shift in origins and the argument it produced.
第四，1965 年之后要说出来源的转变 以及它引发的争论。
Fifth, security against civil liberties is the recurring tension — connect it back.
第五，安全与公民自由是反复出现的张力， 把它连回更早的时期。
