高三化学有机英语阅读理解20题1<背景文章>Organic chemistry is a fascinating and important branch of chemistry that focuses on the study of carbon - containing compounds. Among the many aspects of organic chemistry, reaction types play a crucial role.One of the fundamental reaction types is the addition reaction. In an addition reaction, two or more molecules combine to form a single product. For example, in the addition of hydrogen to an alkene, which is called hydrogenation. The reaction condition usually requires a catalyst, such as platinum or nickel. This reaction is widely used in the food industry to convert unsaturated fats (which have double bonds) into saturated fats.Substitution reaction is another significant type. In a substitution reaction, an atom or a group of atoms in a molecule is replaced by another atom or group of atoms. For instance, the reaction between methane and chlorine in the presence of ultraviolet light. Here, a hydrogen atom in methane is substituted by a chlorine atom. The reaction condition of ultraviolet light is essential to initiate this reaction. This type of reaction is often seen in the synthesis of various organic compounds.Another important reaction is the elimination reaction. In an elimination reaction, a small molecule is removed from a larger molecule,resulting in the formation of a double bond or a triple bond. For example, in the dehydration of an alcohol to form an alkene. Usually, a strong acid is used as a catalyst in this reaction.These reaction types are not only important in theoretical study but also have wide - ranging applications in industries such as pharmaceuticals, plastics, and agriculture.1. <问题1>What is the main feature of an addition reaction?A. One molecule breaks into two or more products.B. Two or more molecules combine to form a single product.C. A molecule exchanges its atoms with another molecule.D. A small molecule is removed from a larger molecule.答案：B。

大学生总是专注于一个特定的学科的英语作文University students always focus on a specific subjectIn today's highly competitive world, university students often choose to specialize in a specific subject in order to excel in their chosen field. This trend has become increasingly common, as students recognize the benefits of focusing their time and energy on a specific area of study.One of the main reasons why university students choose to specialize in a specific subject is the desire to gain in-depth knowledge and expertise in that particular area. By focusing on a specific subject, students are able to delve deeper into the complexities of their chosen field, gaining a thorough understanding of the subject matter. This specialized knowledge can give students a competitive edge in their future careers, as employers are often seeking individuals who have specialized expertise in a particular area.Furthermore, specializing in a specific subject allows students to develop valuable skills that are directly related to their chosen field. For example, a student specializing in computer science will gain practical experience in programming languages and software development, while a studentspecializing in psychology will develop skills in research methods and data analysis. These skills are not only relevant to the student's academic studies but also transferable to the workplace, making them more marketable to potential employers.In addition, focusing on a specific subject can help students to identify their passions and interests, enabling them to pursue a career that aligns with their goals and aspirations. By immersing themselves in a particular area of study, students can gain a deeper understanding of what they enjoy and excel at, leading them to make more informed decisions about their future career path.Despite the benefits of specializing in a specific subject, there are also potential drawbacks to this approach. One potential downside is that students may miss out on the opportunity to explore different areas of study and develop a broad range of skills. This can limit their career options and make them less adaptable to changes in the job market. Additionally, students who focus solely on a specific subject may become too narrowly focused, missing out on the opportunity to develop interdisciplinary skills and perspectives that can be beneficial in the workplace.In conclusion, while there are both advantages and disadvantages to specializing in a specific subject as a university student, it is clear that this trend is becoming increasingly prevalent in today's competitive academic and professional landscape. By focusing on a specific subject, students can gain in-depth knowledge, develop valuable skills, and identify their passions and interests, all of which can help them to succeed in their future careers. However, it is important for students to strike a balance between specialization and exploration, in order to ensure that they are well-rounded individuals who are prepared for the challenges of the modern workforce.。
