Music Do
2
you remember when you first realized that your computer was more than just a monitor and keyboard?
3
That between the mouse click and the video playing,
4
there was something that captured your intention,
5
understood it, and made it real?
6
What is that something?
7
Is it gremlins?
8
Let's imagine that we can shrink down to the size of an electron and inject ourselves into a click of a mouse.
9
If you took your mouse apart,
10
you'd see that it's really a very simple machine.
11
It has a couple buttons and a system for detecting motion and distance.
12
You might have an optical mouse that makes these measurements with lights and sensors,
13
but older ones did this with a hard rubber ball and some plastic wheels.
14
Same concept.
15
When you click the button on your mouse,
16
it sends a message to the computer with information about its position.
17
When your mouse click is received,
18
it's handled by the basic input-output subsystem.
19
This subsystem acts like the eyes and ears,
20
and mouth and hands, of the computer.
21
Basically, it provides a way for the computer to interact with its environment.
22
But it also acts like a buffer to keep the CPU from being overwhelmed by distractions.
23
In this case, the I.O subsystem decides that your mouse click is pretty important,
24
so it generates an interrupt to the CPU.
25
Hey CPU, gotta click here.
26
The CPU, or central processing unit,
27
is the brains of the whole computer.
28
Just like your brain doesn't take up your whole body,
29
the CPU doesn't take up the whole computer,
30
but it runs the show all the same.
31
And the CPU's job, its whole job,
32
is fetching instructions from memory and executing them.
33
So while you're typing, typing,
34
typing, maybe really fast, like 60 words a minute,
35
The CPU is fetching and executing billions of instructions a second.
36
Yes, billions, every second.
37
Instructions to move your mouse around on the screen,
38
to run that clock widget on your desktop,
39
play your internet radio, manage the files you're editing on the hard drive,
40
and much, much more.
41
Your computer's CPU is one heck of a multitasker.
42
But oh my gosh, there's a very important mouse click coming through now.
43
Let's drop everything now and deal with that.
44
There are programs for everything that the CPU does.
45
a special program for the mouse,
46
for the clock widget, for the internet radio,
47
and for dealing with letters sent by the keyboard.
48
Each program was initially written by a human in a human-readable programming language like Java,
49
C++, or Python.
50
But human programs take up a lot of space and contain a lot of unnecessary information to a computer,
51
so they are compiled and made smaller and stored in bits of ones and zeros in memory.
52
The CPU realizes that it needs instructions for how to deal with this mouse click,
53
so it looks up the address for the mouse program and sends a request to the memory subsystem for instructions stored there.
54
Each instruction in the mouse device driver is duly fetched and executed.
55
And that's not nearly the end of the story.
56
Because the CPU learns that the mouse was clicked
57
when the cursor was over a picture of a button on the monitor screen,
58
and so the CPU asks memory for the monitor program to find out what that button is.
59
And then the CPU has to ask memory for the program for the button,
60
which means that the CPU needs the monitor program again to show the video associated with the button.
61
And so it goes.
62
And let's just say
63
that there are a lot of programs involved before you even see the button on the screen light up
64
when you clicked it.
65
So just the simple task of clicking your mouse means visiting all of the critical components of your computer's architecture.
66
Peripherals, the basic input-output system,
67
the CPU, programs, and memory, and not one gremlin.
68

背景与环境
在今天的数字时代，计算机不仅仅是一个简单的显示器和键盘的组合。视频中，Bettina Bair 通过深入探讨计算机的内部运作，揭示了计算机如何通过不断的指令和反馈来实现复杂的操作。了解计算机的基本原理，有助于我们在使用这些工具时更加高效，也促使我们关注英语学习中的语言结构和表达方式。
日常交流的五个短语
- 你能帮我吗？（Can you help me?）
- 我不太明白。（I don't quite understand.）
- 请再说一遍。（Please say that again.）
- 这是什么意思？（What does this mean?）
- 谢谢你的帮助。（Thank you for your help.）
逐步影子跟读指南
在学习英语口语和提高发音时，采用影子跟读（shadow speak 或 shadowspeak）方法是非常有效的。以下是如何有效地进行本视频内容的跟读练习：
- 聆听与理解：首先，仔细聆听视频中的对话，确保你理解每个短语的意思。记下不理解的部分，方便日后查阅。
- 分段练习：将视频内容分成小段。尝试分别练习每一段，以确保能够掌握每个短语的发音和语调。
- 模仿与纠正：在听的过程中，尽量模仿演讲者的语音和语调。如果可能，记录下自己的声音，与原视频对比，找出不足之处。
- 重复练习：进行多次的重复练习，确保发音准确。通过这种方式，你不仅能提高英语发音水平，还能提升英语口语表达能力。
- 运用到生活中：将学到的短语运用到日常生活中，进行实际交流，帮助巩固知识，提高英语口语练习的实际应用能力。
通过这样的方式，学习者能够在实际交流中更加自信，同时提高英语发音及口语能力。坚持影子跟读，必将助你在英语学习的道路上取得更大进步！
什么是跟读法？
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
