202 1 The Last Inventory of Knowledge Points in College Entrance Examination —— Summary of Required Knowledge Points in College Entrance Examination of Mathematics
A, 202 1 final inventory of college entrance examination knowledge points
The number of words is the largest in the college entrance examination results, and there is a lot of room for improvement. So I summarize the learning and knowledge points to be mastered in the final sprint stage for the reference of 202 1 candidates.
1, mathematics
The basic knowledge of mathematics in the college entrance examination is comprehensive and focused. Students' solid mathematical foundation is the key to successful problem solving. The basic knowledge and skills that middle school students should emphasize in college entrance examination mathematics must be comprehensive. And systematically review the high school mathematics foundation, correctly understand the basic concepts, and students should correctly master theorems, principles and formulas to form memories. Students must remember that they should change with constancy.
2. China people
Nowadays, great changes have taken place in Chinese reminders, and the proportion of reading comprehension has greatly increased. Generally speaking, college entrance examination questions are divided into reading questions, composition questions and basic questions. For reading, we should look at the questions first, then look at the full text with the questions, and then locate in the text. Grasp the center of the article as quickly as possible, then answer questions around the center and highlight the center. The key point of the composition is to be accurate in conception, to standardize the beginning and end, to highlight the key points in the text, and then to be accurate in conception and avoid digression.
3. English
NMET English involves more grammar, but from the perspective of proposition trend, NMET English now pays more attention to students' reading skills, mainly including grasping the author's overall thinking, discovering the hidden meaning of the author, inferring new words according to the specific background of the article, and speculating and understanding the information expressed in the article. The proportion of pure grammar questions is very small, and the college entrance examination English no longer pays attention to the understanding of the basic English language, but turns to the examination of language application ability. There are more and more "original" test materials, the proportion of modernity is enhanced, and the genre is more diversified.
Second, the knowledge points of college entrance examination mathematics must return.
Mathematics is a headache for many students, so I have compiled a summary of the knowledge points that must be tested in the college entrance examination for everyone. I hope everyone can check for leaks and fill in the gaps at the final stage.

1, random sampling: (lottery method, random sampling table method) is often used when the population is small, and its main feature is to extract one by one from the population.
2. Stratified sampling: The main feature of stratified sampling is proportional stratified sampling, which is mainly used for people with obvious differences between individuals. * * * Similarity: Every individual is drawn.
Are all equal, n/m.
3. Cluster sampling: When cluster sampling is applied, each group is required to be well representative, that is, the differences between units within the group should be large and the differences between groups should be small.
4. Systematic sampling: When there are many individuals in the group, it is troublesome to adopt simple random sampling. At this time, the population can be divided into several balanced parts, and then an individual can be extracted from each part according to predetermined rules to get the required samples. This kind of sampling is called systematic sampling.
