Is Jiangsu College Entrance Examination Biology Simple in 2020?

It's not that hard. Just some basic questions. In 2020, the biology volume of Jiangsu college entrance examination still emphasizes the reading and analysis ability of coordinate curves, charts and some physiological process charts, and at the same time examines students' understanding ability, application ability and logical thinking ability under the new situation.

Biology, also known as life science and biological science, is a natural science based on empiricism, which extensively studies all aspects of life, including origin, evolution, distribution, structure, development, function, behavior, interaction with environment, biological taxonomy and so on.

Biology is also a compulsory subject at the beginning of junior high school.

Modern biology is a huge and eclectic field, which consists of many branches and disciplines. However, despite the wide range of biology, there are some universal and unified concepts that dominate all learning and research and integrate it into a single and coherent field.

Generally speaking, organisms recognize that cells are the basic unit of life, genes are the basic unit of heredity, and evolution is the engine to promote the synthesis and creation of new species. Today, people also know that all living things maintain a stable and important state by consuming and converting energy and adjusting the internal environment.

Review strategy

Review methods should be appropriate. In the review of biology college entrance examination, three common review methods are generally used.

1, comparative review method

In review, students can compare their knowledge horizontally and vertically by comparison method. For example, the comparison between constitutive enzymes and inducible enzymes, the comparison between prokaryotic cells and eukaryotic cells, and the comparison between the submicrostructure of higher plant cells and animal cells; Compared with the sources and ways of the three nutrients, all three nutrients can come from food, can be stored except protein, and can be partially transformed by other substances.

2. Continuous review method

When reviewing, you can connect the knowledge scattered in each chapter in series, so that students can have a comprehensive understanding of the knowledge. For example, the knowledge about protein is mainly scattered in the first, second and fifth chapters. The first chapter introduces the constituent elements, basic units, synthesis sites, structures and functions of protein. The second chapter describes the digestion, absorption and metabolism of protein in human body.

The fifth chapter discusses that the synthesis of protein is controlled by genes, including two physiological processes: transcription and translation. When reviewing, we can put these knowledge together to make the knowledge more systematic and improve students' ability to solve comprehensive problems.

3. Associative migration method

Such as mitochondria, can be related to respiration, energy converter, cytoplasmic inheritance, enzyme specificity, membrane structure and function, various substrates, cells with a large number of mitochondria, cell aging and so on.

Another example is the review of membrane fluidity, which can be related to active transport, endocytosis, efflux, fertilization, cell fusion, division and transmitter release. Generally there are common thinking, divergent thinking and so on.
