I m in my third year of high school and I m a science student. However, now my life is very poor, es

Biology is to read the book thoroughly, and then do the questions to run-in, in fact, biology is very simple, the knowledge points can be done, all the books are read, because it can take any test, you must prepare two notebooks, one to take notes, this has to be thick, don't wait for the second semester of the third year of high school to make up for it, there is time at all, there is a point of wrong questions and your unfamiliar knowledge points, the first note is usually read, the second is usually read before the big exam, probably that's all, the main thing is to read more books, the questions can't be separated from the book, I wish you success.

As long as you are not afraid of hardship, first of all, books are the key, you must read through the books to remember the knowledge points and typical topics, especially it seems that the exercises after class in books are basic to do will, and secondly, you must buy information to do, and if you make mistakes, you will study to ensure that the next time is good, pay attention to listen in class, so as to ensure that you can achieve your goal, I wish you a happy o

I don't know if your school holds a small-scale exam every week, just read more of the usual multiple-choice questions, and some questions about what kind of hybridization and chromosomes can be read more to understand the principle. When I was in school, I had an average of 2 to 3 exams a week, and I just looked at the multiple choice questions and the big questions at the end. Do more mock papers, and there should be no big problem in the early stage of the college entrance examination.

Grasp the basics, test the books, test the books, and test the books! Go to the last exam syllabus and memorize the knowledge points, biology is the backrest, as long as you work hard, it's very simple.

The construction of biological knowledge system from point to line to surface to body, one round of review to complete this, when your accumulation of quantity to a certain extent, there will be a qualitative leap.

Learn the text! I was in the same situation as you when I was divided! I feel that it is useless to study literature, and the college entrance examination is competitive, but in the end, the results of the college entrance examination still prove that you can only get good results in the subjects you are good at.

Unless you have a great interest in science and have a lot of determination and perseverance to learn physics and biology, don't study science.

It is still recommended that you study literature, the most important thing in high school is grades, and the entrance examination to university is also based on grades, in fact, the major in college has nothing to do with your study of literature and science (except for the major with a particularly strong science orientation). And you are studying now to get into a good university, of course, the score is the most important, to learn the subjects that you can get a high score!

Hope it helps

I also heard people say that the score of literature is high, so I was very scared, but when you really study, these are not problems, you are good in liberal arts, you can also rank very high in the grade, but if you are not good in science, even if it is easy to get into college, it is useless, and it will be difficult for you to be admitted to the university where you study literature. Trust me, I've just graduated from my senior year of high school...

This one... Ask, how bad is your science and what is your foundation? If the foundation is not good, then study the text.

If the foundation is good, it's just that the questions can't be done, and you can make up for it in many ways...

Also, depending on your interests, it's not that you can't do well in the liberal arts exam.

If the child is from Jiangsu, in this case, choose liberal arts.

Jiangsu's three-subject two-level scheme If you choose science and have no interest in physics, it will have a big impact.

As for the literature and comprehensive affairs of other provinces, I don't know much about it.

There are also a lot of science students, and although science is good for employment, it is also for top students.

Don't joke about your future, choose literature, science, you can listen to more classes

Literature, even if you choose science, you will transfer to literature because you can't learn it, and you will be admitted to university.

Web Links. The biology test depends on how many points you want, if you want to keep the basic score, you have to understand all the points in the book, if you want a higher score, in addition to understanding the points in the book, you also need to read a little more questions.

The knowledge points in the syllabus will not change, and there may be several situations where you can't think of the answer, 1The knowledge points themselves can't be used, that is, they don't understand it, so ask the teacher or classmates to explain it again. 2.

I didn't understand the question, and I wasn't sure which point of the test was this question. This is because the knowledge points are not familiar, and they have already understood it when they are taken out, but they lack application, so just look at the questions more. 3.

Some questions are strung together by stringing several knowledge points together, and as before, they can only be practiced.

You are a senior in high school, if it is a senior in the college entrance examination in more than a month, then believe me, we can win if we hold on. I've seen people who went to the teacher's office before the three-model exam, looked for the teacher to sort out the knowledge points three times, and then rose from a score of 50 points in the three-mode exam to a score of 94 in the college entrance examination (a full score of 150, yes, this guy finally passed). At this time, finding the right method is the most important, you have been getting up early and tossing for more than half a year, but you still can't get the score you want, which means that there is a problem in a link that has nothing to do with hard work, and that a god-level teacher will let you get twice the result with half the effort.

This teacher may not have graduated from a prestigious school, but he must know the students best and the routines of answering questions. I once met a classmate who couldn't even say his own **, he didn't even know how to open his mouth to ask, but after reading his papers, he knew the problem, this kind of teacher is the one you are looking for.

The worst result is that there is no promotion, then the college entrance examination is a team battle, if you can't make up for the shortcomings, then let your other planks improve as much as possible. That's how I got the admission letter, and it's very easy.

If you are a prospective senior in the college entrance examination in June next year, then don't panic, my classmate who passed the exam after hugging his thigh a few times can do it, you have so much time, everything is possible. The exam is a group of teachers digging holes to trick you, sweeping away the loopholes in a down-to-earth manner, and then cooperating with the answering skills.

The words I speak are a little unstable, I'm afraid that you will be too nervous before the exam, so I will make you happy and wish you all the best.

The biology is more than the same as the back of the figure.

Personally, I think it's very likely that the biology teacher is not attractive enough to you.

I'm a sophomore in high school like you, and I'm about in the top five in school.

It is very stressful to share a table with classmates with good grades, whether it is listening to lectures or writing homework, I often can't help but want to know how the other party is learning, and I always want to surpass others. Then, this "I'm not as good as others" thinking can put us in a passive position in our learning and can't find our own rhythm.

Take it easy, now is the time for review, I believe you have laid a solid foundation in the past two years, don't think that the basic knowledge taught by the teacher in class is not important, review the basics in class, and you can do review materials more handily after class.

As for what you said about not having confidence in the mathematics of the college entrance examination, hehe, don't worry, the college entrance examination questions are still difficult for us, especially the science comprehensive (I am deeply touched, it took three nights of self-study to write a science comprehensive test paper). You can do special training in mathematics first, and gradually increase the difficulty.

As for Chinese and English, they belong to the language category, and I don't think there's anything to remember, it's purely a love for languages. If there is anything, English is to listen more, read more, buy a booklet, and memorize words. Chinese, read more magazines, such as Youth Digest, Reader, Fashion Digest, Most Digest, Essay Soloist, Full Score Reading, are all good choices.

I'm in the key classes, so I'll try to relieve the pressure.

1. Set short-term goals for yourself, and discuss with your parents to achieve the goals and get the rewards you want most, as a motivation for your learning.

2. Communicate with good friends to talk about your troubles and help solve psychological problems.

Study advice:

1. In the first round of review, attention should be paid to reasonable arrangement of time to ensure sleep 2. You can review and preview in your spare time.

3. Start with the basics to make up for mathematics, and don't be ambitious.

4. The college entrance examination paper can be done in sections, as long as you have time, you can do one or two questions, and you should focus on homeworkOf course, physical health is the most important thing!!

It's useless how good it is at ordinary times The key is the last one I can experience At that time, there was a person in our class who went to make up classes every day When I was in the second year of high school, I was the first in the class In the third year of high school, I can always be about 50 points higher than the key line When I get to the college entrance examination, I don't go to the key point lower than me So you don't want to be blinded by superficial phenomena Don't pursue vanity The college entrance examination score is the reality I just studied very hard But at that time, I didn't finish the review and took the comprehensive test The score was only more than 2a10 points Later, I didn't give up and insisted on following the teacher The grades are rising step by step Hard work may not be effective for a while, it is necessary to have an opportunity, at that time, I was 4 points off the key line, and it has been this result since then, and it is also 4 points behind the college entrance examination, which is not high, but it is very satisfying, it is the result of your own efforts, so you also have to believe in yourself.

Relax your mind and not be in a hurry. Find a good question, finish it seriously, and review it again. It's much more effective than doing a lot of questions.

Keep it up like that. Put a good mentality, be strong, sometimes this is also a kind of motivation, the key is to deal with it yourself.

The most difficult thing is Mendel's law, if this study will not be recommended to give up, the exam will go a form, the card is the pass rate, the exam pays attention to methods and skills, first get the score to get the rest of the fill on the line As long as you don't write Newton, Einstein, and Darwin, I wish you a successful pass.

You're from Zhejiang. It's okay, the Zhejiang Entrance Examination is super simple, I never listen to physics and chemistry in class, and the results are A, Biology B, the teacher will send an outline before the exam, and the biology key teacher will speak, just memorize it. Coupled with a reasonable guess during the exam, I believe you can pass the exam!!

Remember to make a few more mock papers.

Chapter to the back! It won't take much time!

I teach biology, so I'll talk about how biology can improve in a short period of time.

First of all, you need to make an analysis and summary of the test papers you have taken to see where your biology problems are, and then combine your own situation to make breakthroughs and improve in a targeted way.

Multiple choice questions, which are the weight of most students who do not score well. If you memorize it and know the knowledge points, then the reason for the low score should be that your problem-solving skills and ability to find the problem points can still be improved. Then it is recommended that you do the multiple-choice questions of the college entrance examination questions in the past 3 years, the keywords in the questions are drawn out, and the reasons for each option are clarified, so that although the amount of questions is not very large, the effect will be very obvious, slowly, you will see the keywords as soon as you look at the questions, and grasp the questions to ask.

The target is guaranteed to 5 and strive for 6.

The big questions are now 4 big questions + 1 elective in the national paper.

The electives are relatively simple, and it is recommended that you organize the knowledge points into a system to ensure that you get a score of 12 points or more.

In recent years, the questions of the national paper examination have been relatively fixed, and the following question types appear more frequently:

1. The question of the combination of photosynthesis and respiration.

2. Genetic calculation (9:3:3:1 deformation and autosomal inheritance plus companion inheritance) 3. Regulation of vital activities.

4. Judgment of ecosystem components and calculation of transfer efficiency.

It is recommended that you choose the two with the higher scores in general, focus on breakthroughs, and strive for as many points as possible. For those who usually do questions without thoughts, it is recommended to put them first, it may be too hard to do the questions, consolidate the basic knowledge, and try to get points. In this way, the score of the two major questions is about 20 points.

30 (choice) + 12 (elective) + 20 (big question) = 60 I give my students this training now, basically do it seriously, and you can achieve this goal in a week.

I already have the answer, but I'll send it to you when I'm done.

It is well established that the loss of water and the absorption of mineral elements, as well as the absorption and absorption of mineral elements, are simultaneous in time. These are two different processes, which we call relatively independent processes, because water absorption and water loss are both through the free diffusion of water molecules and through water channels, both of which belong to passive transportation. The absorption of mineral elements relies on the carrier proteins on the cell membrane to consume ATP energy, which we call active transport, and these two processes can indeed occur at the same time, because they cannot be sequenced first.

For example, do plants absorb or lose water first, and then wait until they do not lose water to absorb water, and then absorb mineral elements? Of course it can't, it's impossible to wait until one process is over and then start another, so in terms of time, it can indeed be done at the same time, but with a different mode of transmembrane transportation.

aqui te amo。

The root system absorbed K+ and NO3- through active transport from the beginning, and the fresh weight increased after 6 hours, indicating that the water absorbed by the root cells lost more water than transpiration, and the ion concentration in the root cells was higher than that of the external solution, which should start before 6 hours, but the water absorbed by the root cells was less than the water lost by transpiration, so the fresh weight was still decreasing. The number of ions absorbed by active transport in root cells is increasing, and the water absorption is also increasing, and the ion concentration in root cells is changing. After 12 hours, because the root system of group A continuously absorbs K+ and NO3- through active transport, so as to maintain the concentration difference between the inside and outside of the root cell, so that the water absorption is greater than the transpiration and exceeds the fresh weight before treatment, the concentration of cell fluid at point B is higher than that of A, and the transport mode of water continues to absorb water is passive transport
