Luyện nói tiếng Anh bằng Shadowing qua video: How America became a superpower
Đang tạo bài học...
1
The modern United States is the most powerful country in human history.
2
With over 800 military bases and 37% of global military spending, the United States has become the leader of a vast interconnected global system that has helped usher in an era of unprecedented prosperity and low levels of conflict.
3
To understand America’s position in the world, and why it’s so pivotal for world politics as we know it, you have to go back to the country’s founding — back to when America wasn’t a global power in any sense of the word.
4
During the first 70 years of its existence, the United States expanded in both territory and influence in North America eventually reaching the Pacific Ocean in a wave of expansionism that resulted in the wholesale slaughter of the indigenous people who populated the continent.
5
But early Americans were deeply divided as to whether the country should expand beyond the Pacific and Atlantic oceans.
6
This became a major debate after the civil war, when some leaders, like post-war Secretary of State Seward, argued that America should push to become a global power.
7
Seward succeeded in pushing a plan to purchase Alaska from Russia, but his attempts to buy Greenland and Iceland, as well as annex territory in the Caribbean, were all blocked by Congress.
8
That’s because some Americans, including many on Capitol Hill, had a strong anti-imperialist bent.
9
These people worried about America getting more involved in global politics, as well as having to integrate populations from “inferior” races.
10
And this opposition applied major checks on the imperialist urge to expand.
11
But something was happening in the late 1800s that would change the debate about American expansionism.
12
The industrial revolution produced explosive economic growth, and the bigger US economy required a more centralized state and bureaucracy to manage the growing economy.
13
Power became concentrated in the federal government, making it easier for expansionist presidents, like William Mckinley, to unilaterally push United States influence abroad.
14
The key turning point came in 1898, when President McKinley dragged the country into war with Spain over the island of Cuba despite intense opposition.
15
The rising US easily defeated the moribund Spanish empire, acquiring Puerto Rico, Guam, and the Philippines in the process (1898).
16
Over the next two years, the US would annex the Kingdom of Hawaii (1898), Wake Island (1899), and American Samoa (1900).
17
A few years later the US took control of the Panama Canal Zone (1903) and sent troops to occupy the Dominican Republic (1916), it also purchased the American Virgin Islands (1917).
18
This period of rapid acquisition of far flung territories put the US on the map as a truly global power.
19
During this time, America also began using its influence to protect its growing commercial and military interests abroad, installing pro-American regimes in places like Nicaragua and playing a major role in international diplomacy regarding the Western presence in China.
20
World War I showed how just how much America’s influence had grown.
21
Not only was American intervention a decisive factor in the war's end But President Wilson attended the Paris Peace Conference which ended the war and attempted to set the terms of the peace.
22
He spearheaded America’s most ambitious foreign policy initiative yet, an international organization, called the League of Nations, designed to promote peace and cooperation globally.
23
The League, a wholesale effort to remake global politics, showed just how ambitious American foreign policy had become.
24
Yet isolationism was still a major force in the United States.
25
Yet isolationism was still a major force in the United States.
26
Congress blocked the United States from joining the League of Nations, dooming Wilson’s project.
27
During the Great Depression and the rise of Hitler, the US was was much more focused on its own region than on European affairs Ultimately, though, America’s ever-growing entanglements abroad made it impossible for it to stay out of global affairs entirely.
28
In East Asia, the growing Japanese empire posed a the direct threat to American possessions and troops bringing the United States and Japan into conflict.
29
This culminated in the Pearl Harbor attack bringing the United States into World War II.
30
World War Two would transform America’s global presence forever.
31
The United States was the only major power to avoid economic ruin during the war, and it was the sole country equipped with atomic weapons.
32
As such, it was in unique position to set the terms of the peace — and, with the aim of preventing another war in mind, it took advantage.
33
The most famous example of this is the creation of the United Nations.
34
The UN charter set up a system of international law prohibiting wars of conquest, like the ones waged by the Nazis and the Japanese.
35
It also served as a forum in which the international community could weigh in on disputes, and help resolve them.
36
This way, the Americans hoped, great powers could resolve their differences through compromise and law rather than war.
37
But while the UN is the most famous of the post-war institutions, it isn’t the only one.
38
730 delegates from all 44 Allied nations came together in a small vacation haven in New Hampshire. Their goal? To establish a global financial system that would prevent another Great Depression and World War.
39
The resulting agreement, called the Bretton Woods Agreement ultimately became backbone of the global financial system.
40
Resulting in the World Bank and the International Monetary Fund.
41
By creating these institutions the United States committed itself to being deeply involved in the world’s problems.
42
The issue, though, is that the world’s second-largest power — The Soviet Union — saw things differently.
43
World War II had made allies out of the democratic West and communist East in the fight against Hitler, but that couldn’t last.
44
The United States saw Soviet expansion in Eastern Europe and elsewhere as a direct threat to its vision of a free-trading world.
45
"To a substantial degree, in one form or another" Socialism has spread the shadow of human regimentation Over most of the nations of the earth And... the shadow is encroaching on our own liberty.
46
Fearful of Soviet intentions towards Western Europe, the US and other European nations created the North Atlantic Treaty Organization, a military alliance meant to stop Russia from invading other countries in Europe.
47
Globally, the US committed to a strategy called “containment” — so called because it was aimed at containing the spread of Communism everywhere on the globe.
48
This new global struggle meant that the US had to exert influence everywhere, all the time.
49
Instead of disbanding the massive military machine created for World War II, its wheels mostly kept turning.
50
This had two main results: first, the US was pulled into unlikely alliances with countries like Saudi Arabia, Israel, and South Korea, seeing each of them as bulwarks against communist influence in their region.
51
Secondly, the US began intervening, often secretly, in dozens of countries to contain Soviet influence.
52
Sometimes this meant propping up sympathetic dictators like in Iran, other times supplying rebels with arms and money like in Afghanistan in 1979 and Nicaragua in 1985.
53
Over the course of the Cold War, the US intervened in hundreds of disputes around the globe, ending up with a complicated set of alliances, tensions, and relationships in basically every corner of the earth.
54
After the Berlin wall fell, the US could have withdrawn from this system, severing ties with its allies and drawing down the size of its military.
55
And while the US did military spending, much of the military infrastructure and alliances from the Cold War war remained.
56
Presidents George H.W. Bush and Bill Clinton decided that it was in both America and the world’s interests for the United States, now the sole superpower on earth, to continue actively managing global affairs.
57
" We should be and we must be Peacemakers" NATO, created solely as a tool for countering the Soviets, stayed together and even expanded, a way of keeping European nations united in the absence of the Soviet threat.
58
Washington’s support for countries like Israel and Japan stayed intact, ostensibly as a means of preventing war in those regions.
59
The global system of alliances and institutions created to keep the peace during the Cold War became permanent — as did the American military and political commitments needed to keep them running .
60
This system remains in operation today, and no leading American politician since the Cold War has seriously called for dismantling them — except, perhaps for Donald Trump.
61
Trump has said contradictory things about these commitments.
62
But he’s consistently argued that American allies are not paying America enough for its protection, and questioned the value of free trade.
63
That calls NATO and even the World Trade Organization into question.
64
At some point, we have to say, you know what, we're better off if Japan protects itself against this maniac in North Korea.
65
We're better off if South Korea is going to start to protect itself -- and Saudi Arabia?-- Saudi Arabia? Absolutely.
66
This is a sharp divergence from the consensus that has dominated US foreign policy since 1945, and something closer to the isolationism that came before it.
67
So will President Trump act on some of candidate Trump's ideas, and reverse decades worth of institution building and alliances?
68
We'll find out, soon enough.

Những Gì Bạn Sẽ Học Được
Trong video này, bạn sẽ khám phá những khía cạnh quan trọng trong việc phát âm tiếng Anh chuẩn và cách mà lịch sử hình thành các cường quốc toàn cầu ảnh hưởng đến ngôn ngữ. Cụ thể, bạn sẽ học được:
- Cách sử dụng ngữ điệu và nhịp điệu tự nhiên khi nói chuyện về các sự kiện lịch sử.
- Các thuật ngữ và cụm từ liên quan đến chính trị và kinh tế, giúp nâng cao từ vựng của bạn.
- Cách thể hiện ý kiến cá nhân một cách rõ ràng và thuyết phục khi thảo luận về các chủ đề phức tạp.
Lắng Nghe Những Âm Thanh Này
Khi xem video, hãy chú ý đến cách mà người nói kết nối các âm thanh với nhau. Bạn sẽ nghe thấy:
- Các âm nối giúp lời nói trở nên mượt mà hơn. Ví dụ, khi người nói chuyển tiếp từ câu này sang câu khác mà không dừng lại.
- Những từ được rút gọn hoặc phát âm nhanh để tạo cảm giác tự nhiên và gần gũi hơn.
- Cách người diễn đạt sự nhấn mạnh trong câu, điều này rất quan trọng để biểu đạt cảm xúc và ý nghĩa.
Bạn có thể luyện nghe nói qua video này để cải thiện kỹ năng của mình, và sử dụng phần mềm shadowing để thực hành theo cách mà người nói thực hiện.
Nói Như Một Người Bản Xứ
Để nói như một người bản xứ, bạn cần chú ý đến nhịp điệu và sự nhấn mạnh trong ngôn ngữ. Trong video, người nói thường:
- Sử dụng nhịp điệu không đều, với những phần được nhấn mạnh rõ ràng và những phần khác được nói nhanh hơn.
- Kết hợp giữa việc nói chậm và nhanh để tạo sự thu hút cho người nghe.
Bạn có thể thực hành shadowing tiếng Anh bằng cách lặp lại ngay sau khi nghe, điều này sẽ giúp bạn cải thiện phát âm và tăng cường sự tự tin khi nói. Hãy cố gắng bắt chước không chỉ âm thanh mà cả cảm xúc và nhịp điệu của người nói. Khi bạn luyện tập, hãy nhớ rằng việc sử dụng các phần mềm shadowing có thể giúp bạn theo dõi tiến bộ một cách hiệu quả hơn.
Ngữ pháp trong video
Những cấu trúc người nói dùng nhiều nhất, kèm đúng cụm từ trong video:
| Cấu trúc | Trong video |
|---|---|
| Thì hiện tại hoàn thành have/has + quá khứ phân từ — việc đã xảy ra nhưng còn liên quan đến hiện tại | has become · has spread · has said |
| Câu bị động be + quá khứ phân từ — nhấn vào việc xảy ra, không phải người làm | was aimed · was pulled |
Phương Pháp Shadowing Là Gì?
Shadowing là kỹ thuật học ngôn ngữ có cơ sở khoa học, ban đầu được phát triển cho chương trình đào tạo phiên dịch viên chuyên nghiệp và được phổ biến rộng rãi bởi nhà đa ngôn ngữ học Dr. Alexander Arguelles. Nguyên lý cốt lõi đơn giản nhưng cực kỳ hiệu quả: bạn nghe tiếng Anh của người bản xứ và lặp lại to ngay lập tức — như một "cái bóng" (shadow) đuổi theo người nói với độ trễ chỉ 1–2 giây. Khác với luyện ngữ pháp hay học từ vựng bị động, Shadowing buộc não bộ và cơ miệng phải đồng thời xử lý và tái tạo ngôn ngữ thực tế. Các nghiên cứu khoa học xác nhận phương pháp này cải thiện đáng kể phát âm, ngữ điệu, nhịp điệu, nối âm, kỹ năng nghe và độ lưu loát khi nói — đặc biệt hiệu quả cho người luyện IELTS Speaking và muốn giao tiếp tiếng Anh tự nhiên như người bản ngữ.
