DAVID MALAN: Hello, world.
2
My name is David Malan, and this is CS50, Harvard University's introduction to the intellectual enterprises of computer science and the art of programming for majors and non-majors alike.
3
Indeed, whether you're among those less comfortable or more comfortable with technology, this course, and computer science more generally, are in fact for you.
4
And it is free via platforms like edX, YouTube, Apple TV, Google TV, and CS50's own website.
5
Through this course, you'll learn how to think more methodically, more algorithmically, so to speak.
6
You'll learn how to communicate succinctly and precisely, and you'll learn how to solve problems efficiently with code.
7
Indeed, this course begins at the very beginning with a very friendly graphical programming language called Scratch, via which you'll write code by dragging and dropping puzzle pieces that only interlock together if it makes logical sense to do so.
8
We'll then transition to C, a more traditional keyboard-based language, via which you'll learn how computers work underneath the hood, so to speak.
9
Thereafter, the course moves on to Python, a more modern language via which you can analyze data, automate processes, build web applications, and more, and SQL, via which you can read and write lots and lots of data in databases.
10
Toward course's end, we'll dive into HTML, CSS, and JavaScript, languages with which you can create web apps and mobile apps alike.
11
And at course's end, you'll design and implement your very own final project for the world to see.
12
You will have learned how to program.
13
And if at any point you get stuck, there's a whole CS50 community to support you, as well as nowadays a virtual rubber duck of whom you can also ask questions anytime, thanks to AI.
14
All this and more, this is CS50.

练习建议
在进行英语影子跟读的过程中，您可以运用本视频内容练习发音和语言流利度。为了更好地掌握这些技能，建议您在观看视频时，尽量模仿讲者的语调和语速。这一过程不仅能帮助您增强听力理解能力，还能提升您的口语表达能力。实践时，可使用shadow speech方法，逐句复述讲者的内容，特别是对于较快的言语节奏，保持专注并反复练习将是关键。此外，您可以在使用shadowing site进行练习时，进行雅思口语练习，以便提高自己的应试能力。通过持续的练习，您将在英语会话中变得更加自信和自然。
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。
