Detailed description
A chemical reaction is a process of changing the state of a substance, manifested as the breaking of old chemical bonds and the formation of new chemical bonds. In chemical reactions, the substances involved in the reaction undergo processes such as electron transfer and atomic rearrangement, forming new substances.
Choosing the appropriate reagents and drugs is crucial for the success of the experiment. It is necessary to understand the characteristics, uses, and storage methods of various reagents and drugs.
Glassware
Experimental instruments
Reagents and drugs
Before starting the experiment, one should fully understand the purpose, principle, and steps of the experiment. Prepare the necessary experimental equipment and reagents and ensure the safety of the laboratory environment.

6 Chemistry has improved the quality of our life to a great extent. Thanks to numerous chemical discoveries, our life has become easier and more comfortable.
2 Chemicals provide fertilizers for agriculture, and fertilizers provide the nutrients that crops need to grow. Pesticides are another way in which chemicals contribute to agriculture, as they can be used to control insects, weeds, plant diseases, and other pests that affect crop or animal production. Both fertilizers 译 and pesticides help promote crop growth and production, and they have been indispensable in agricultural production.

3. 后置定语多
即位于其所修饰名词之后的定语。科技英语由于语 言习惯与汉语的差异，还有为了强调所修饰的名词， 都将定语后置，定语越长，越易后置。
例如： Besides, isomerization processes may also take place which in turn leads to other fairly complicated reaction.

3.理解原著事理，注意逻辑判断
对原文的理解过程中，单纯靠语法分析往往不易 了解句子的真正含义，要判断句子的真正含义， 还必须通过逻辑判断，对句子的结构、语言环境、 上下文和事理关系进行综合分析才能奏效。如句 子中的代词指代的是哪一个？定语从句的先行词 是哪个？否定句中否定的对象和重点在哪里等。
例如：
The machine works properly.“运转” Force is any push or pull that tends to
produce or prevent motion.
例如：
The moment the circuit is completed, a current will start flowing toward the coil.
handled in the less space. 连续过程通常能节省操作空间。(adj.→v.)
