Ask you some questions about your high school studies ,,, ask for help! 50

I'm now in my second year of high school, and I'm leaning towards literacy and reason.

The knowledge of the first year of high school is not very difficult, the most important thing is to listen to the lectures in class, to be efficient, and you must not be distracted, like English or something, the use of phrases and phrases taught by the teacher, you must remember it in class, so that you don't have to waste time in class. You don't need to complete all the homework, and I guess you teachers can't have to accept it, right? If you look at those assignments, if it is a repetitive question type, a copied thing, don't write it if you don't have time, and pick the homework that you think is useful and valuable, because the role of homework is to consolidate knowledge, and repetitive things are also a waste of time.

The other thing is to write the homework for the next day.

Mathematics is a big head, come on, learn mathematics well, success and mathematics, failure and mathematics, mathematics is successful, if you are not weak in other subjects, it is generally no problem. Math homework must be written, and it should be written in the first subject, and math must not be written before going to bed.

If you want to learn how to learn, there are a lot of words, if you look up on the Internet if there is something that is not suitable, you can ask me.

In addition to the number of words, this is the key, the early stage is paved, and the later grades will go up, although the grades determine the fate, but if you don't enter the key class, you can make yourself less stressed.

If you want to talk about the method, that's a lot, the key is to do it, I understand you, because I'm about the same as you, I'm in my third year of high school, I made a mistake in the first year of high school, and I didn't get into the key class when I was in the second year of high school, and I seized the opportunity to get into it, and we had about 1,300 students in a grade, and I took the 35th place at that time, but then I found out that there was still a gap in one year The commonality of people in the key class is fast Efficiency is a necessary condition for being an excellent student, but that's not all, it's still accurate, so you say that self-study can't be learned? Absolutely not! If you can't learn it, you have to learn!

No matter what others are doing, as long as they don't pull you out of their seats, you have to be single-minded Only when the heart is like stopping water can you win by surprise Don't think that you have enough questions Especially in science You have to do more questions than homework There is no bad reason But the wrong questions must be studied again Don't lose them Because the key to doing so many questions is to find out yourself** will not It doesn't matter if you can't do it for a while, remember it in the wrong question book It's really not okay to ask the teacher After writing down the ideas, read a word in liberal arts Memorize! And then nothing else.

Method 1: Use a small notebook to memorize the new words you encounter when doing the problem Look up the dictionary and carry it with you while walking.

2. Make good use of ***

3. More teacher questions.

4. Establish a problem book for each subject, one for each subject, and insist on using it.

5. Homework Develop an agile mindset.

When you want to memorize words in English, read them several times first, and you can also put the words into the text to memorize. Regardless of the subject, pay attention to the lectures during class. Review in time after class and do some exercises to consolidate.

Do your homework selectively, choose the important ones, and then practice the speed more.

Focus on the sub-subjects, take the plan you have made in the sub-subjects, the first year of high school, the math, English, physics, and composition. In the second year of high school, the liberal arts students are, of course, mathematics, and the science students are science comprehensive, and in the third year of high school, English, and disadvantaged subjects. Russia only said the outline of the plan, and you can configure it according to your own situation and the information you find.

Regarding homework, if you have done or will definitely do it, don't do it, plagiarism is okay, and if it is vague and challenging, do it. When you don't want to study, you can do your favorite subjects, and you can do weak subjects when you study time. Self-study time should be used to start with interest, read essays, improve the level of composition, or read English magazines, and think while reading.

Ambition is much stronger than I was back then You can divide it into modules The first month focuses on one subject, the second month focuses on another subject, and so on.

We will be happy to answer your questions and hope to help you.

Simply put, you want to get good grades to live up to the expectations of your friends and family, right?

First of all: you have to forget about the expectation of making money because you want to make money, you can't study, you say you sit in the classroom, you will sleep, right, it's because you don't get enough sleep, I hope you can go to bed early, now let's talk about reading, it's better to find your best friend to study with when you are studying in school, of course, he must have better grades than you! When you get home, review it and you're good to go, and then you can put a refreshing cup of coffee on the table!

When you are in class, you must pay attention to the book, so that you can save a lot of time, and I can only say this to you, good luck.

You have to cheer up, make up for the lessons you missed before, and don't get sleepy anymore, because if you go on like this, it will ruin your body.

Are you short of money to use, and you have learned the basics well. After you have knowledge, you can earn several times more money than you earn now, haven't you thought about it like this?

First of all, your current mentality is not right, and you must correct it! If you don't learn a lesson well in junior high school 2, then you don't want to learn it anymore, and the questions in the back are more in-depth in the previous questions.

Typical misanthropy. It is recommended that you communicate with your parents and tell them about your situation to see if you can find a solution. I know you've heard it more than you know how many times, and it's hard for you to do it if you understand it.

Hehe. I found that you are very similar to one of my classmates in my first year of high school.

But he's not as hesitant as you are, and some of his symptoms are very similar to yours, but he was addicted to the Internet in his freshman year of high school. Finally, the shift is assigned to the errand shift. But he is not discouraged.

In the third year of high school, I worked hard. Finally in an important exam in the year ranked second. Prove yourself and impress others.

In the college entrance examination, he was admitted to Wuhan University, a national key university,——. (He's just as mentally minded as you are).

Actually, I have the same process as you. However, I was successful in the high school entrance examination, but I was very confused in high school. But then I got my heart out. I also went to a good university.

Support you. Make yourself better.

The sample size of the sedan car and the pass [110,120) 12 can be calculated as: 40, so that the frequencies of the following groups can be calculated: [90,100) (source 2).

It can be found that 40-2-8-12-11-4-2=1 is 1 40=is closed and prematurely stared 4 40= is the sum of frequencies and must be 1

Derivative f'(x)=x^2-2ax+a^2-1

1. If x=1 is the extreme point of f(x), then x=1 is f'(x)=x 2-2ax+a 2-1 0.

Substituting a 2-2a = 0, the solution gives a = 0 or a = 2

2. If the tangent equation of the image of f(x) at the point (1, f(1)) is: x+y-3=0, then the tangent point is (1,2).

and f'(1) = 1, i.e. 1 2-2a*1+a 2-1 -1, solution a 1

then f'(x)=x^2-2x

f(x)=x^3/3-ax^2+(a^2-1)x+b＝x^3/3-x^2+b

Substituting the tangent point (1,2) into f(x) gives 1 3-1+b 2, then b 8 defeats 3, so f(x)=x 3 3-x 2+8 3

On the intervals (-2,0) and (2,4), f'(x)>0；On the interval (0,2), f'(x)<0；When x = 0 or 2, f'(x)＝0

Therefore, the function f(x) has a tendency to change in the interval [-2,4] as follows: increase-decrease-increase.

Sketching shows that the maximum value of f(x) in the interval [-2,4] is either at x=0, or at x=4.

f(0)=8/3，f(4)=4^3/3-4^2+8/3=8

So the maximum value of f(x) over the interval [-2,4] is 8
