Methodological Guidance for Junior High School Biology Competitions Introduction 20

How junior high school students want to participate in the biology competition.

1. First of all, we must be clear about the prospects of the biology major, really want to do it, and still want to do it after understanding the possible disadvantages, and then continue to plan. Personally, I think that if you can be admitted to top schools, such as the resumption of diplomatic relations in the Northern Qing Dynasty, as well as the National Academy of Sciences and Zhejiang University, then many problems of student biology will be easy to solve. If you don't have enough strength to get into these, you still have to be cautious.

In addition, I don't know if agronomy is acceptable, in fact, I think Chinese agronomy is also promising, and the main impact is to look at the false name.

2.If you want to study biology, there is really nothing to say about biology in middle school, it is very simple. The focus is actually on mathematics, physics and chemistry. If you want to engage in biology, you must learn mathematics, physics and chemistry well. If you can't do science, you're not good at biology. In the future, majors will also be affected.

3.You can read the relevant chemistry books in advance, the biochemistry part of the biology competition is the focus, if you can't learn this part, don't bother, if you are not interested, then you can, it is worth going.

4.Is there a tradition of competitions in the high school of the future, especially in biology? Of course, if the school itself is good enough, it is more important than having a tradition of biology competitions.

If the school does not have a tradition of biology competitions, it will have to rely on institutions. But for high school leagues, the institutions certainly can't keep up with the support of the schools.

5.The centroid of the institution is very good, and you can consider Beidou to brush the question later.

6.Self-learning ability is very important, and the biology competition is basically to learn all the courses for the graduate school entrance examination in college, and you can buy some books to read first. Textbooks are not expensive, if you buy them and think it's okay to study on your own, then you can rest assured to devote yourself, if you feel that you can't read them, then reconsider.

7.The advantage of the biology competition is that the sophomore league will be the last in May. If the results are not good, there is still time to transfer back to the UEC.

8.If the target is the resumption of diplomatic relations in the north of the Qing Dynasty, then it is best to get the provincial first in the first year of high school, and the second year of high school will impact the provincial team. Saving one alone doesn't help.

But not being able to get the provincial one in the first year of high school does not mean that you must not be able to enter the provincial team in the second year of high school, but it is definitely more difficult. Tianjin's biology competition is moderately weak, similar to Beijing's.

Summary. The National Biology Competition for Middle School Students tests the knowledge of university biology, so the preparation is very clear.

First of all, find Chen Zengyue's General Biology, which basically includes all the content of the exam.

Then find multiple sets of real competition questions, do more and memorize, and you can pass the initial test.

Who has participated in the National Biology Knowledge Contest for Middle School Students and how did they prepare?

I wish you the title of the gold list.

The biology competition is divided into two exams, the league and the national competition, and some provinces also have a preliminary round and a provincial selection.

1. Preliminary round: Before the National Biology League, some provinces will organize a preliminary examination. The only purpose of the preliminary examination is to qualify for the league in the province.

Exam content: The difficulty of the preliminary round in some provinces is close to the college entrance examination, and some provinces are close to the league, so students from provinces with preliminary examinations should still prepare carefully and practice before the league.

2. League: In the May exam, "Province 1", "Province 2" and "Province 3" refer to the league award.

The league will be followed by a provincial selection: the provincial selection is an examination that selects 8 members of the provincial team, and the selection is for the students who have won the "provincial one" award of the provincial league.

The scope of the league's exams is relatively wide, and the difficulty is basically between the college entrance examination and the national biology competition.

Cell Biology, Biochemistry, Microbiology, Bioinformatics, Biotechnology 25%.

Anatomy, physiology, structure and function of tissues and organs of plants and animals 30%.

Animal Ethology, Ecology 20%.

Genetics and Evolutionary Biology, Biological Systematics 25%.

The final scale may be adjusted each year, as is the final score.

3. National Competition: The team members participating in the national competition are all members of the provincial team of each province, and since the provincial team is 8 people, there are generally about 240 people participating in the national finals every year.

Exam content: Animal Biology, Plant Biology, Biochemistry, Molecular Biology, Cell Biology, Ecology, Plant Physiology, Animal Physiology, Genetics, Biotechnology and Bioinformatics.

Experimental: Animal Biology, Plant Biology, Ecology, Behavioral Sciences, Physiology and Biochemistry, Molecular Biology.

When I participated in the biology competition last year, there were two stages: the preliminary round and the semi-final. I am from Changzhi City, Shanxi Province. In the preliminary round, he was in Taihang Middle School in the city, and after entering the semi-finals, he went to the high school attached to Taiyuan Normal University to take the exam.

After the exam, I actually think that most of the questions have to be memorized, and I can find a few more sets of competition questions from previous years to do, and I can encounter a lot of original questions during the exam. The knowledge points of the test are not deep, but the content of the test is very broad. The knowledge points are very fragmented.

It's just to see how much you know. Our preliminary round is really more than three months, and the semi-final is.

I was the first prize of the provincial biology competition and entered the provincial training. Help you explain:

The first is the provincial competition (provincial competition), which should be the provincial preliminary competition you are referring to.

After passing the preliminaries, there is the semi-final stage (that is, the National Biology League), which is a unified proposition by the whole country, and the examination and award are carried out by provinces. The semi-final is first of all a theoretical examination, and those who have excellent results in the theoretical examination (no more than twice the number of first prizes in the province that year, generally about forty) enter the experimental examination stage. In the end, the total score (theoretical and experimental examinations are added up in proportion) is awarded the first prize (the number of first prizes is more than 20, which is related to the number of winners in the national finals of the previous province, which is 27 in our year).

Then, according to the ranking, the former is selected from the first prize to form the provincial training team, and then the members of the provincial team are selected from the provincial training team (selected according to the results in the training, which has nothing to do with the previous competition results. 4 members).

After entering the provincial team, he represented the province in the national finals. The first, second and third prizes were awarded in the finals. If you win the first prize, you will have the opportunity to participate in the national training team, and finally you may enter the national team and participate in international competitions.

Among them, if you win the first prize in the provincial division of the national league, you will get extra points for the college entrance examination (it seems to be canceled now, but in fact, the discounts of each institution still exist) and the qualification for the guaranteed examination (you can be guaranteed by passing the guaranteed examination, and well-known universities can generally apply for the guaranteed examination).

If you win the first prize in the national finals, it will be easier to send (there will be a chance to sign a contract on the spot), and the school is better (like Peking University).

I obtained the qualification for the escort examination with the certificate of the provincial first and provincial training team, passed the escort examination, and obtained the escort qualification.

We will be happy and always happy to help you in any way we can.

Fourth, there are many professional forums and knowledge platforms on the Internet, and there are also a lot of information on them, and I always go to the forum to seek solutions to professional problems.

Fifth, ask your questions more carefully and clearly! It's easier for people to understand what it means!

Thanks for taking my suggestion! !

The first question is 2nm, put? The answer is b

2) Actually, I won't. Sorry to forget now.

3) D is not true.

The amount of evaporation is much higher than the amount of the outflow book. This means that the effect of root pressure is very small. Although there is a relationship between the state cavity outflow and both, the conclusion above is that it has nothing to do with root pressure, which is to say that it is mainly affected by capillary forces.
