1
Problems.
2
We've all got them.
3
You, me, T -Swift, Tony Stark.
4
Some problems, like forgetting to do your homework, might seem like a pretty big deal to you.
5
But when you compare them to other, bigger problems, they're really not so bad.
6
Like what kind of bigger problems?
7
Well, the kinds of problems engineers face, like how to safely fly hundreds of people through the air in a small vehicle from one country to another
8
or how to make an eco -friendly building in a seaside town
9
that can withstand hurricane -force winds or how to send a bunch of earth -bound humans hurtling off into space and, you know, get them back.
10
That homework doesn't seem like such a big problem anymore, does it?
11
Okay, to be clear, I'm not saying that you don't have to do your homework.
12
If you didn't, it would definitely be a problem, just not as big as, like, having to invent a spaceship.
13
And that's the kind of stuff that engineers do.
14
Engineers are people who want to know how and why things work.
15
Not only that, they actually design and build things like machines, systems, or structures to help solve specific problems.
16
All engineers, whatever type they are, follow the same series of steps when trying to solve a problem.
17
You'll remember these steps as the engineering process.
18
And the first step in that process is defining the problem, when an engineer identifies a problem he or she hopes to solve.
19
But that first step isn't as simple as you think it is.
20
So it's time for our big question.
21
How does an engineer define a problem?
22
Let's come up with a fake problem to solve and we'll see what we wind up with.
23
Pretend you're on one side of a very big canyon and you need to get to the other side.
24
So that's the problem you need to solve, right?
25
How to cross this very big canyon.
26
Sort of, but not exactly.
27
We can do better.
28
If I was an engineer and found myself on one side of that huge canyon, here's how I'd go about identifying the problem.
29
I'd ask questions.
30
A lot of questions.
31
All the questions!
32
Hmm.
33
I need to cross this very big canyon.
34
But is that my actual problem?
35
Hmm.
36
This canyon is very big and I need to get to the other side.
37
I know!
38
I'll cross a bridge!
39
Wait, is there a bridge?
40
Uh, yeah, there's no bridge.
41
Okay, can I climb down one side of the canyon and then up the other side?
42
Uh, definitely not.
43
Way too deep.
44
Plus there's a roaring river at the bottom I'd have to figure out how to cross.
45
So, I can't cross the canyon by bridge, I can't climb down and up, and I can't swim across it.
46
What's something I can do that doesn't require a bridge, climbing, or swimming?
47
I know, I need to find a way to fly across the canyon.
48
And that's my problem.
49
More importantly, that's my solvable problem.
50
How do I fly across this very big canyon?
51
It took a little bit of thinking and a whole lot of questions, but how can you fly across the canyon is an easier problem to address than the much less specific,
52
I'm on one side of a big canyon and I want to get to the other side, and I don't know how to get across it.
53
Which, strictly speaking, isn't a question.
54
It's just complaining about a problem really loudly.
55
So defining the problem in a solvable way is really key to being a good engineer.
56
While that first step might seem pretty easy, make sure you treat it like the super important step that it is, because it sets the stage for all of the steps of the engineering process that follow.
57
If you don't define a potentially solvable problem from the start, you might never, well, solve it.
58
So an engineer asks a lot of questions to define a problem as specifically as they can, and most importantly as something that can be solved.
59
So how is engineer Sabrina going to find a way to fly across that gorge?
60
You're gonna have to solve that problem by watching our next lesson.

本片段的口語學習目標
通過模仿影片中的對話，提升用英語清晰描述問題、邏輯思考的能力，同時掌握工程領域相關表達。適合練習“shadow speech”（影子跟讀），通過同步複述增強口語流暢度與反應速度，達成能有條理闡述問題的流利度里程碑。
實用短語庫
- compare them to...（將它們與……相比）
- withstand hurricane-force winds（抵禦颶風級風力）
- follow the same series of steps（遵循同一套步驟）
- define the problem（定義問題）
- solvable problem（可解決的問題）
- set the stage for...（為……奠定基礎）
攻克薄弱點
影片中大量使用疑問句與邏輯推理句式，如“How does an engineer define a problem?”“I need to cross... but is that my actual problem?”，適合練習英語疑問句的語調與節奏。通過“英語影子跟讀”，重點模仿升調在疑問句中的運用及思考過程中的自然停頓。建議使用“shadowing site”進行反覆練習，注意區分陳述句與疑問句的語調差異，同時強化長句的斷句能力，避免因語速過快導致邏輯模糊。
影片中的語法
說話人最常用的結構，並附上影片中的原話：
| 結構 | 影片中的用法 |
|---|---|
| 用 “might / may” 表可能 might/may + 動詞 — 有可能但不確定的事 | might seem |
| 義務：must / have to / need to 表示某事是必要的 | have to do · having to invent · need to get |
| “will” 表將來 will + 動詞 — 決定、承諾或預測 | You'll remember · we'll see · I'll cross |
| 現在進行時 am/is/are + -ing — 此刻或近期正在發生的事 | I'm not saying · is defining |
什麼是跟讀法？
跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧，最初開發用於專業口譯員的培訓，並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大：您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同，跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性，語調，節奏，連讀，聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
