Is it better to study chemistry or biology?Chemistry and biology had their own advantages and disadvantages. The following was an analysis from several aspects:
** 1. Discipline research characteristics **
1. Chemistry
- Chemistry was a basic subject that studied the structure, properties, and laws of change of substances. It included organic chemistry, organic chemistry, analytical chemistry, physical chemistry, and many other branches. Chemistry research often required a deep understanding of microscopic atoms and molecular structures. Through various experimental methods, new substances were synthesized and the composition and properties of substances were analyzed. For example, in the field of organic synthesis, scientists were committed to synthesizing organic compounds with specific functions. This required a precise grasp of the reaction mechanism, the formation and breaking of chemical bonds, and so on.
2. ** Creature **
- Biology studied the structure, function, development, and evolution of living things, including molecular biology, cell biology, genetics, ecology, and other sub-disciplines. Biological research focused more on the various life phenomena in living organisms, from the molecular level to the macro ecosystem. For example, the study of gene expression and regulation in molecular biology needed to start from the structure and function of biological molecules such as DNA and protein to explore the nature of life phenomena.
** 2. Difficulty of Postgraduate Entrance Examination **
1. Chemistry
- The chemistry entrance exam required candidates to have a solid foundation. They had to master the basic knowledge of organic chemistry, organic chemistry, analytical chemistry, physical chemistry, and many other branches, and they had to be able to skillfully apply it to solve practical problems. For example, in the written examination for the chemistry entrance examination, there were often a large number of questions such as writing chemical reaction equations and material structure analysis, which required a high level of knowledge.
2. ** Creature **
- The difficulty of the biology postgraduate entrance examination mainly lay in the investigation of the overall quality. Not only did the candidates need to master the basic knowledge of biology, but they also needed to assess their comprehensive qualities in many aspects such as experimental skills, data analysis skills, and English proficiency. In biological research, the acquisition and analysis of experimental data, as well as the tracking of international cutting-edge research results, all required a good level of English. Moreover, the operation of biological experiments was complicated, and the uncertainty of the experimental results was high. It required high experimental skills and data analysis ability.
** 3. Job prospects **
1. Chemistry
- Chemistry majors had a wide range of employment fields, and there was demand in the chemical, materials, pharmaceutical, energy, and other industries. For example, in the chemical industry, chemistry graduate students could engage in the research and development of chemical products, the optimization of production processes, and other work. In the pharmaceutical industry, they could participate in drug synthesis, drug analysis, and other work. However, the chemical industry may face certain environmental and safety risks, and the working environment of some chemical companies may be relatively poor.
2. ** Creature **
- Biology majors could be employed in the fields of pharmaceutics, biotechnology, and biomedicine engineering. With the continuous development of biotechnology, the employment prospects of biology majors were gradually expanding. For example, in the field of pharmaceutics, graduate students could participate in the research and development of biological drugs. However, the job market for biology majors was also highly competitive, especially for high-end positions that often required higher academic qualifications or rich experience.
** 4. Interesting research and sense of accomplishment **
1. Chemistry
- For people who liked to explore the mysteries of the material world and create new things, chemistry research was very attractive. When a new compound was successfully synthesized or a new chemical synthesis method was developed, there would be a strong sense of accomplishment. For example, developing an efficient and environmental catalyst was of great significance to the improvement of the chemical production process.
2. ** Creature **
- In biological research, when the molecular mechanism behind life phenomena was revealed or new ideas were provided for the treatment of diseases, it would bring great satisfaction. For example, research breakthroughs in the field of gene therapy were expected to bring hope for some difficult diseases.
In summary, it was impossible to simply determine whether it was better to study chemistry or biology. It needed to be considered based on personal interests, professional foundation, career planning, and other factors.

What would the parents of third-graders write?The following was a thought process for a third-year student's speech at the parent-teacher conference:
** I. Opening Welcome and Thank You **
1. The opening ceremony gave a warm welcome to the parents, such as,"Dear parents, hello! Thank you very much for taking time out of your busy schedule to attend this third-grade parent-teacher conference."
** 2. Cultivation of students 'psychological quality **
1. ** Cultivation of independence **
- It was pointed out that most of the third-year students were only children and were taken care of at home, so it was easy for them to develop the habit of dependence. For example, many children lived a life of "food comes to their mouths, clothes come to their hands". They only focused on studying and lacked the ability to live and study.
- Parents should be encouraged to let go appropriately and let their children learn to be independent. Even if they encounter setbacks, it would be a harvest under the guidance of parents. It emphasized the need to change the concept of education and pay attention to the long-term and all-round development of children. The standards for assessing talents in society were in many aspects, including a healthy personality, mental health, social adaptability, and so on, not just test scores.
2. ** Cultivate the child's "tolerance"**
- It explained that children might be self-centered at home, that their social circle was small, and that they only looked at their own strengths and the shortcomings of others.
- Parents are advised to take their children to public places, let their children play with their companions, and cultivate their children's open-minded and optimistic personality in the activities. This will lay a good psychological foundation for their children's future study and life, because children with small tolerance are easy to find trouble.
3. ** Cultivate the child's initiative **
- It emphasized the importance of psychological quality to the child's life. Children were easily motivated by small things, and parents should learn to share the joy of success with their children.
- It was pointed out that children's enthusiasm for learning was mostly driven by external factors. For children who were temporarily lagging behind, parents and teachers should give confidence, guide learning methods, and help them overcome difficulties. If the child was reprimanded, beaten, and scolded for the slightest mistake, it would dampen his enthusiasm and affect his development.
** 3. Learning **
1. ** Changes in learning content and requirements **
- It meant that the third grade had a wide range of learning content, and the requirements for students were higher. They had to have a solid foundation, expand their thinking, and think from different angles.
- He mentioned the increase in the content of the courses, such as the new English class, moral and life class, and science class.
- He pointed out that the learning method should be changed from mechanical memory to understanding memory. Each subject should train the child's spatial thinking, abstract thinking, summary ability, imagination ability, etc., instead of focusing on specific image thinking.
2. ** Parents 'response to learning changes **
- Teachers would use a variety of teaching methods in the classroom to stimulate students 'interest in learning. Parents should also think about how to help their children take this step, clarify their learning goals, correct their learning attitudes, and develop good learning habits. For example, to train children's ability to arrange their time reasonably, some children could quickly start doing homework after school without supervision; some children could develop a study plan and routine that suited them, such as playing the piano at a fixed time every day and completing homework; some children cultivated their hard-working character through participating in competitive competitions and were also among the best in their studies.
- As Year 3 students enter a new phase of writing, parents can help their children in the following ways:
- Starting from imitation, when writing things, people, scenes, and activities, pay attention to writing the process in detail, plus feelings, to avoid writing it down as a running account.
- To stimulate interest in writing, to be a person with a heart for life, to record life, to write feelings, observations, or a documentary diary, to extract good words and sentences.
- Bring the child into contact with society, read more books and newspapers, and study social phenomena.
- Read thousands of books and travel thousands of miles to accumulate life experience and reading materials. You can take your child on a trip.
- In Chinese studies, one must persist in reading, expand the amount of reading, and ensure the quality of reading. One must think and record reading, because Chinese is the foundation of all subjects.
- He could prepare a set of wrong questions for his child, copy down the usual wrong questions and difficult questions, and review them at the end of the unit, mid-term, and final term. The effect was better than brushing more questions.
** 4. Ending **
1. To express their expectations for their parents and children, for example," Every child is unique. Although there are individual differences, as long as our family and school work together, we will definitely be able to help the children improve. We hope to see the children grow up healthily and achieve academic success in the future." Thank you again for coming, parents!"

What should I do if my child has a fever repeatedly and does not defecate?When a child has a fever and does not defecate, the following methods can be used:
1. * * To clarify the cause of the disease **
- If you suspect that it is the flu, the flu often has high fever and does not go away. You should go to the hospital for diagnosis and treatment as soon as possible. If necessary, use flu-specific drugs such as oseltamivir.
- In addition to the flu, it may be a respiratory infection caused by other viruses or bacteria. Such children may have a fever for 2 - 3 days, and the body temperature may subside for 2 - 3 days before starting to have a fever again. The doctor needs to further differentiate the diagnosis.
- There may also be repeated infections, such as cross-infection when waiting in the hospital, which needs to be taken care of.
- Infected with uremia could also cause fever. It was common in school-aged children (5 - 9 years old). They often had symptoms such as high fever and severe irritating dry cough. Their blood routine tests did not have a specific pattern like typical bacteria or viral infections. A chest X-ray was often needed to assist in the diagnosis.
- It could also be caused by bacteria infection such as suppurative tonsillitis, scarlet fever, etc. There was also a small number of children with autumn diarrhea who had high fever, and repeated high fever should also be considered for rare diseases such as Epstein-Barr virus infection and Kawasaki disease.
- From the perspective of traditional Chinese medicine, it might be a fever due to food accumulation. In the early stages, it was generally manifested as a hot stomach, a hot palm, a large temperature difference between the stomach and the back, and a large temperature difference between the palm and the back of the hand. Before the fever, there would be stool obstruction or diarrhea. If the fever was due to food accumulation, it could be digested first before the fever subsided. However, it was necessary to pay attention to not immediately resume eating after the initial fever subsided.
2. * * Care and Coping **
- Don't stop taking the medicine immediately after the temperature drops. The use of antibiotics can't be stopped as soon as the temperature drops to prevent a second high fever.
- Make sure that the child is resting. The disappearance of the body temperature does not mean that the child's condition is completely cured. It is still in the recovery period. At this time, rushing to attend classes, attending cram schools, rushing homework, etc. will make the illness relapse.
- When taking the child to the hospital, let the child wear a mask and reduce group activities and public access to reduce cross-infection.
- During the period of fever, let the child drink more water and eat a light diet. You can eat more leaves, vegetables, sweet potatoes, bananas, etc. You can also put white radish shreds in the fish soup (which helps to improve the defecation situation). At the same time, you must ensure that the child defecates every day. You can adjust the diet structure, such as eating more fruits and vegetables, to develop the habit of defecating regularly every day. Usually, pay attention to massaging the abdomen clockwise with the navel as the center. If there is a bacteria infection, it is best to choose antibiotics against the pathogen when using medication. Antibiotic treatment usually takes 3 - 5 days, and some infections need to be treated for 7 days or even two weeks or longer. You must use the medicine under the guidance of a doctor and do not stop the medicine at will.
