Anonymous users2024-02-08I was also in my sophomore year of high school and entered the Bio League. Most of the test questions are only learned in college biology, so you'd better borrow college textbooks from your teacher, and you should borrow them too, right?? Our teacher used his college textbook to teach us.
To grasp the time to see often, can remember the concept of the amount of notes, time is limited, you have to rely on memory, one of my classmates took the national second prize in this way, and then firm confidence, don't be afraid of problems, you are afraid, others are also afraid.

Anonymous users2024-02-07I have to say that I am lucky to be able to enter the semi-finals.
The knowledge reserve for the competition is almost zero, and it is a bit difficult to take the semi-finals.
If your high school foundation is good enough, the second and third prizes in that province are definitely not a play (the first province is definitely not a play) Now I want to review systematically, it is unlikely, it is recommended to watch general biology several times.
Plants, zoology, if you have time, take a look.
The rest is harder to figure out.
You can consider taking a look at the previous league questions, which should help.

Anonymous users2024-02-06High School Biology Competition... It felt thunderous
It seems that the main thing is that there are more subdivisions of animals and plants, and there are a lot to memorize, and it is useless to learn ......Khan
Shift the focus to cellular biochemistry ......
As LS said, watch "General Biology"!
Botany" memorizes the structure of some common types of flowers (a lot of tests are taken each time.。。 ）

Anonymous users2024-02-05I am also a student biology competition, and I hope my will help you in your future studies.
Biochemistry and genetics are more difficult, and it is impossible to learn well in a month or two, give up. Take a look at some questions before the exam, and you may be able to come across something similar.
For general zoology and botany, turn it over once or twice, and then do the questions. This part is very simple, and the score is small, only about 15 points. Plant physiology and animal physiology are key to scoring. This part is not too difficult, look at the Olympiad classics and then do the questions, to a large amount.
For the rest of the questions, just look at the questions a few days before the test.
I mentioned a lot of topics, and I recommend buying a copy of the topics published by Zhejiang University.

Anonymous users2024-02-04I also happened to enter the semi-finals, the situation is almost the same as you, I think I should consolidate the foundation first, and finish most of the general questions, now I want to climb the difficulty is basically hopeless, do your best!

2. Watch "General Biology", this is the top priority!

Anonymous users2024-02-02Look at the "Elite Lesson Plan" biology exercise collection, this book is a special one! As long as you memorize the above questions, it is possible to save one.

Anonymous users2024-02-01Let's take a look at general biology.
Plants, animals are mainly structural and reproductive.
Heredity is mainly the content of genes.
Biochemistry is mainly sugar metabolism.
It's important to look at the question.

Anonymous users2024-01-31There are certain benefits, which are as follows:
1. Participating in the biology competition can take the content of classroom learning, and further expand the amount of knowledge reserve, so as to prepare for university study in advance. Sensitive ruler.
2. Participating in biology competitions can improve the ability to adapt to changes, exercise mental quality, and prepare for other large-scale exams, such as the college entrance examination.
3. Participating in biology competitions can increase the probability of going to prestigious schools, and some prestigious schools pay more attention to the competition awards and practical abilities won by students.
High school biology competitions are useful. It is an opportunity to exercise one's professional knowledge and expression skills, ability to resist pressure, and psychological quality. If you can win a national award, you can also get extra points in the college entrance examination.
In fact, you don't have to be so nervous, you may just put too much pressure on yourself, relax, and the workbook or something wrong is a good thing, learn more lessons, don't miss it again, and the review before the exam is very important, I usually look at the notes, and then see that I am not very familiar with the will be memorized, and then 5.3 wrong questions to see more, but there is no need to do 5.3 in the second year of high school, you can try my method, maybe it will get better.
Dizzy, buy a reference book.
First, the dominant recessive nature of albinism and sickle anemia was determined, and according to the left half of Figure 1, it can be concluded that anemia is a recessive genetic disease, which is bb; Then look at Figure 2, because if it is normal, it can be cut, and if it is not normal, it can't, so B is normal, C is albino, and both are homozygous, only A is heterozygous (because A can cut out three pieces: DNA is a double helix structure, only one of A can be cut, B can be cut all of them, cut into two short and two long, C is not cut) Because albinism is a recessive genetic disease, it is AA, so it can be known that B is AA and C is AA >>>More
