Is it difficult to test the chemistry test paper in Zhejiang college entrance examination? Is there an analysis and answer of the test paper?

1.Is it difficult to test the chemistry test paper of Zhejiang college entrance examination in 2022? In 2022, the difficulty of the chemistry test paper in Zhejiang college entrance examination may increase, and the trend of the difficulty of the 2022 college entrance examination exposes the proposition orientation of the 2022 college entrance examination published by the senior high school entrance examination, which points out the direction for candidates to prepare for the exam. The overall goal is to pay attention to the development and progress of science and technology, social and economic development and excellent traditional culture. The characteristics of the question type are as follows: first, flexible and open examples examine the imagination of candidates, and there are many groups of correct answers and various problem-solving schemes to choose from; Second, appropriately set up ill-structured questions to examine candidates' understanding of the nature of chemistry, and guide middle school chemistry to attach importance to cultivating chemical core literacy in the teaching of chemical concepts and methods; Third, open questions in an orderly way, to examine candidates' logical reasoning ability and operational problem-solving ability, to reflect openness, and to examine the accuracy and order of candidates' thinking.

Second, Zhejiang college entrance examination chemistry answer notes and guidelines, non-multiple choice questions: close to the core questions to answer.

What are the answering skills for non-multiple choice questions?

1. Focus on the status quo

When doing situational questions, we should not only consider whether the answer conforms to the chemical principle, but also consider whether it conforms to the reality of life and production. For example, coating oil on the surface of iron products can prevent iron from rusting, but coating oil on iron hangers will not rust. For another example, iron wardrobes and cars are painted not only for rust prevention, but also for beauty.

2. Around the core issues

When examining the questions, we should make clear the design intention of the questions, find out the direction of answering questions, and organize the answers around the core of the questions. For example, experimental design questions, experimental inquiry questions and even comprehensive calculation questions all involve experimental purpose or inquiry purpose. Everything you do should serve the purpose of experiment or inquiry, and don't deviate from the core.

Answer in the most common way.

The answer to open-ended questions is not unique. When answering questions, you should choose the most appropriate answer as much as possible, and it is not easy to lose points by answering in the most common way. If you can answer with specific substances, use specific substances, which is more accurate. Try to write your most confident, uncontroversial and acceptable answer, and don't give others the opportunity to deduct points.

4. Analyze in logical order

From "known" to "unknown", analysis and thinking should have a logical order. It can be chronological or spatial order. For example, we can look for several experimental phenomena according to the spatial order from left to right and from top to bottom, and we can also think about them in the time sequence before, during and after the reaction. Some open questions have no ideas, and when the brain is blank, you can search chapter by chapter.
