Chemistry is usually thought to be more difficult than other subjects, at least for the beginners. There are some reasons for this idea. For one thing, chemistry has a very specialised vocabulary. At first, studying chemistry is like learning a new language. Also, some concepts of chemistry are hard to understand. However, with hard work and careful study, you can finish this subject successfully—and even enjoy it. Here are some suggestions to help you develop good study habits and better understand the topics in the book.
化学通常被认为比其他学科更难，至少对于初学者而言是这样。这种看法有几个原因。首先，化学有一套非常专业的词汇。一开始，学习化学就像学习一门新语言。另外，化学中的一些概念很难理解。然而，通过努力和认真学习，你可以顺利地完成这门课程，甚至乐在其中。这里有一些建议，帮助你养成良好的学习习惯，并更好地理解书中的主题。
Firstly, attend classes on time. Focus on what the teacher writes with a chalk on the blackboard and take careful notes in class. If possible, always review the topics you learn in class. Do not be afraid to ask others for help.
第一，按时上课。注意老师用粉笔写在黑板上的内容，并在课堂上认真记笔记。如果可能的话，经常复习你在课堂上所学的内容。不要害怕向他人寻求帮助。
Secondly, think whether you really understand the meaning of a term. A good way to test your understanding is to explain a concept to a classmate or someone else.
第二，思考你是否真正理解了某个术语的含义。检验理解能力的一个好方法是把一个概念解释给同学或其他人听。
Thirdly, pay attention to things which have something to do with chemistry in life. Do experiments in the lab actively to gain experience.
第三，关注生活中与化学有关的事物。在实验室积极做实验，以积累经验。
Fourthly, aim to earn an award or medal in school science fairs to recognise your hard work. Have candy or a cookie after finishing a challenging project. This can serve as a reward for yourself.
第四，力争在学校科学展览会中赢得奖项或奖牌，以肯定你的努力。在完成一个有挑战性的项目后，吃点糖果或饼干，作为对自己的奖励。
You will find that chemistry is much more than numbers, formulas and equations. It’s often used in daily life just like maths and physics.
你会发现，化学不只是一些数字、分子式和方程式。它像数学和物理一样，经常被用在日常生活中。
