If you curious about biology or plan to study it in the future, you may be wondering what“prerequisites”it has—that is, what other knowledge will give you a soild foundation learn biology. If so, big kudos for thinking ahead！
如果你对生物学非常感兴趣或打算在未来研究它，你可能会疑惑学习它有什么前提(注：需要提前具备的知识或素养)—就是，有什么其他知识会为你学习生物学一个坚实的基础。如果是这样的话，你会为预习而感到很高兴！
In my opinion, the only strict prereqs for biology are curiosity, an open mind,and a willingness to think critically about the natural world, If you have those, you can start learning biology without other background, as. long as you're willing to pick up bits of chemistry, physics, statistics, and math along the way.
在我看来，对于学习生物学唯一需要先具备的是有好奇心，一个发散的头脑和乐意去用批判性的目光看待这个自然世界。倘若说你已经有了 你就能开始学习生物学没有其他背景知识，只要你愿意去重新学习一些化学、物理、统计学和数学的知识在学习的过程中。
That said, you may find your journey through biology smoother and more satisfying if you already have some familiarity with topics in other areas, particularly chemistry.Below are some foundational topics that will help you get the most out of Khan Academy's biology materials （or any biology class）
就是说，如果你已经具有在其他领域相关的知识，特别是化学，你会感到你的学习过程更顺利，更令你满意。以下是一些能帮你最大利用好可汗学院生物学学习课程的基础学科（或任何生物学课程）。
General science skills The scientific method.Are you rusty on what a hypothesis is or how it gets tested? How about experiments? These basic concepts will help you not only in biology, but also in any other area of science!
常规科学技能
科学方法。你是否对假设是什么或它如何被证伪感到生疏?对科学实验了解多少?这些基本概念不但会在生物学帮到你，在其他任何领域同样起作用!
Chemistry General chemistry. Get a feel for atoms, molecules, and how they interact with each other. After all, that's what you( and all life) are made up of! Acid-base chemistry. A lot of the chemistry in your body is acid-base chemistry that takes place. in watery solutions. knowing what acids and bases are will get you a long way with biologychemistry.
化学
基础化学。对原子、分子和它们之间是如何交互作用的有一个大概的认识。毕竟，这是组成你（和所有生命）的东西。
酸碱化学。在你体内的许多化学物质就是那些在水溶液中发生反应的酸碱化学物质。了解什么是酸和碱会对你学习生物化学大有裨益。
Physics Laws of thermodynamics. Get a feeling for what Genergy is and what rules govern its transfer. Energy is constantly flowing through ecosystems, organisms, and cells , and is essential to keep these systems running.systems
物理
热力学定律。对什么是能量和是什么规则支配着它的转移有一个初步认识。能量持续不断地在生态系统、有机体和细胞中流动，是支持这些系统运作的根本!
Statistics Basics of probability. Probability is a key concept in biology. You don't need to know tons of details or formulas, but if you understand the basic concepts, that will help you a lot with genetics and population genetics. Statistics. Remind yourself about the basic ways we can describe sets of data, such as mean, median,and mode.If you go even deeper and learn about hypothesis testing, you'll definitely be ahead of the curve!
统计学
基础概率。概率是生物学中的重要概念。你不需要知道成吨的细节和公式，但如果你理解它的基础概念，它会在遗传学和群体遗传学中帮到你大忙。
统计初步。学会我们描述一系列数据，比方说平均数、中位数和模型的基本方法。如果你更深入和了解了证伪实验。你的学习过程会变得异常轻松!
Math Basic algebra and graphing. Most intro bio classes are not that math- intensive, but having an understanding of basic algebra and graphs( e.g, the meaning of slope) will help you understand figures and data in biology.
数学
基础代数和图表。大多数生物学入门课都没有对数学有多大重视，但对基础代数和图表（例如，坡度的定义）有一个认识会帮助你理解生物学中的数据。
Do l have to know all these before starting? Not necessarily!As l mentioned, you can also learn as you go, you just need to be willing to work on these topics in parallel with your learning of biology. if you haven't yet mastered all of these topics. Case in point:I was the poster for how not to prepare for biology classes.I never took physics in high school, and didn't take it in college until l was a junior! I was was also behind on my chemistry classes for most of undergrad. while l don't recommend that approach, it goes to show that a motivated person can be successful in biology even if s/he is “catching up” on some of the prereqs
我得了解所有这些内容再开始学习吗?
当然不！正如我所提到的，你可以边学边把这些内容补上。你只需要在学习生物学的同时，愿意也将这些内容一同进行，如果你还没有掌握这些内容的话。
典例:我并不是一个为如何准备生物学课程而生的人。我从未在高中学过物理课，直到我是个大三学生的时候！我的化学成绩也落后于大多数本科生。尽管我并不推荐这一方法，它就在表明即使是一个仍在补习生物学所需要具备的东西的人也能在生物学上取得优秀成果。
What if l don't like[ chem/physics/stats/math] Don't be deterred from biology if some of these topics are not your favourite( yet!). Biology is a huge, diverse field. All bologists need to have some basic foundational understanding of chemistry, physics, math, and statistics . But they don't have to become specialists in all these topics. Also, if you had a bad experience with one of these topics in the past. why not give a shot on Khan Academy! You may find it's more fun than you expect!
如果我不喜欢[化学/物理/统计学/数学]会怎么样?
如果其中的一些学科内容是你不喜欢的，请不要被生物学吓倒（你只是目前不喜欢！）。生物学是一门广阔，多彩缤纷的领域。所有的生物学家需要有一定的基础，对化学、物理、数字和统计学的基础认识，但他们不需要在每一个领域都成为专家。
此外，如果你过去在某一个学科遭遇过挫折，为何不在可汗学院试一试呢！你会发现它比你想象更有趣！
