Seek help!! Learn things to do, experienced masters come!

You may be someone who isn't good at making plans, but that's okay, take it one step at a time.

1. Find out what is the reason for the lack of concentration in class, try to follow the teacher's train of thought, and don't think about it.

2. Lack of action, devote yourself to one thing before you can report, and train yourself to focus on things.

3 to have confidence in yourself, three books are also this, but the premise is to do your best without regrets.

4. Learning can start from the first, the point is that you are willing to learn, and you must learn with your heart, very hard, very harvested, not necessarily; Ten hard work, one harvest, sure!

5. The plan does not have to be forced, the flexible use of time, and reasonable arrangement are the truth.

6 Finally, of course, it is willpower, if you persist for a week, the effect is not great, but if you persist for a month, there will always be improvement.

7. Learn to communicate with others, and understand your troubles when you talk to the teacher, faster than you can think about it, please give some advice to the teacher.

ps: In English, I will give you a few useful tips:

1 word memory is very very important drops, you are sure that you have memorized the words or not, understand and memorize deeply.

2. Read it aloud, memorize beautiful passages, and read it a few times to have a sense of language.

3. Sorting out the wrong questions is a must, you can't make a second fall, and you will find it very helpful to stick to it.

4. Read English magazines frequently, and the information is convenient and expandable.

PS again: Speaking of the third year of high school, it does make people sweat.

There is a lot of pressure in the top class, and basically I personally think that the best way to relax is as follows:

1 Listen to **, although old-fashioned, but really** heart, I often listened to enya at that time, and Richard. Clayderman's piano music is relaxing.

2. Fooling around with roommates (except at home), generally making trouble, laughing, and feeling much better.

3. Exercise, this is up to you, play whatever you like, just sweat.

4 Reading books, I choose to read a few meters of comics, in fact, magazines are better, informative, and relaxing.

5 in a daze, hehe, it's not cool to try in vain.

6 graffiti, what you want to write, what you want to draw, vent it.

7 walks, one person, or several.

8 and so on. Mood is important, and adjustment is of course crucial.

English, buy this five three do it. There are not many review materials, one is enough.

Listen every day, you can listen with your eyes closed when you are tired of reading, and sharpen your ears more;

Writing: Write one article a week, find a teacher to correct it separately after writing, and memorize more sample essays and templates.

The last sentence is to insist, not to be greedy.

The above is a little bit of my advice, I hope it can be useful to you.

I wish you success in the college entrance examination!

Hehe, like me, people who don't want to learn English. I think I can still do it if I get 90 in English. Keep doing the exercises.

English is all about sticking to it. For other subjects, class notes are indispensable. There are more teachers to discuss and discuss.

Take a look at the materials outside of class.

You need to relax first.

Relax your mind, practice English more, and do English questions regularly every day

Take a break first, listen to the ** relax, find English to focus on review, and memorize words and sentences. Finally, put your mind at ease and review what you have read in your head. I do this every time I take the exam, and the effect is pretty good (*.)

Try to keep an English diary, then find bilingual reading materials that suit you, squeeze about 1 to 2 hours a day to read, memorize 10 words before going to bed, review after getting up, stick to it, and then cooperate well with the teacher, 90 is not a problem.

Relax your mind, read more (the prerequisite is to memorize words), naturally form a sense of language, and the answer will appear fluently in your mind when you encounter a question. That's the trick, it's the same for everyone.

I think you're nervous because you're afraid that you won't be able to get into college! The most important thing you should do now is to relax your mind and face the college entrance examination calmly!

If the mentality is not adjusted well, it is difficult to make a breakthrough.

Personally, I think that your current state is due to being too impatient, and the more anxious you are, the more counterproductive it is. Here are my recommendations::

1.Analyze your strengths and weaknesses, which ones can be raised in the short term, and which ones are a matter of ability. For example, if a certain chapter of mathematics is weak, it is very easy to do, and it will be effective in a few days; On the contrary, for example, the score of the essay is always not too high, which cannot be improved in the short term, and it is useless to get angry.

2.Make a realistic plan for your weaknesses. For example, if you are not good at reading English, then practice reading at a fixed time every day.

3.Accumulate mistakes and schedule a fixed time to review.

The college entrance examination is like a battle, as the saying goes, "know yourself and know your opponent, you will not be defeated in a hundred battles", you must arrange your time and review in a down-to-earth manner. After analyzing my own situation, I decided to give up this part, only do the basic questions, while maintaining the advantage of English language, focusing on geography and politics, and the results proved that my policy was correct My geography and politics advanced by leaps and bounds, and the college entrance examination was extraordinary, and I didn't look at the finale of the inequality of 12 points in mathematics, but mathematics did not give me points, and I still got my wish.

Finally, I remind you to set achievable goals according to your abilities, adjust your mentality, and calmly meet the college entrance examination. I wish you success in the college entrance examination!

Well, this, it seems a little difficult, if you don't listen, you can, but the best thing is to practice reading, memorize more English compositions, and memorize more words. But be sure to stick to it.

Analysis: 1Phenylhydrazine reacts with aldehydes or ketones to form phenylhydrazone, so it can be confirmed that rock bidine is not aldehyde or ketone. 】

2.The conditions under which the iodoform reaction occurs are:

Compounds with a structure of CH3CO- attached to H or C.

2) Compounds with CH3CHOH-R structure (can be oxidized by hypohalide to CH3CO-).

3) Enols (molecular rearrangement occurs).

4) Other compounds that can be oxidized by hypohalide to this structure.

Therefore, it can be determined that [B is not CH3CHOH-R or enol structure] can react with Feilin reagent, A, Zaodong C cannot, so it can be determined, [B is aliphatic aldehyde] 1) so B may be CH3-CH2-CH2-CH2-CH2-CH3 (butyraldehyde) A may be CH3-CH2-C-CH3 (butanone) OC may be CH3-CH2-C=CH2 (2-hydroxy-1-butene) OH2) aldehyde group-CHO

3) CH3-CH2-C-CH3 (METH) + H2N-NHPH CH3-CH2-C = N-NHPH

Iodoform reaction.

(1) Substituting two points A and C to establish two equations can find two unknowns B and C

2) The triangle EBC is based on EC and the height is OB, on the basis of the first question, we can know OB (that is, the ordinate of B), and then we need EC, EC=known, and find OE. Using triangle similarity, OE ob=OP AO, everything except OE is known and therefore solvable.

3) If d is on the axis of symmetry, the abscissa of d can be obtained, and the ordinate of p is required. The same triangle similarity can be used to solve the equation, and there are multiple combinations of triangle alleys that can be used, and you can choose at will.

1. Set yourself some time limits. It is easy to get bored by studying for a long time, so you can divide the homework into several parts, and set a time limit for each part, such as completing the exercise within an hour, completing the test before 8 o'clock, etc., which will not only help improve efficiency, but also do not cause fatigue. If possible, gradually reduce the time it takes, and soon you will find that what used to be an hour away can now be done in forty minutes.

2. Don't do other things or think about other things while studying. Everyone understands the truth that one mind cannot be used for two purposes, but there are still many students who are listening while studying**. You may say that listening is a good way to relax your nerves, so you can concentrate on studying for an hour and then relax and listen for a quarter of an hour**, which is much better than doing homework with headphones.

3. Don't review the same subject all night. I used to watch math or physics at night, and it proved that it was not only exhausting, but also ineffective. Later, I arranged to review two or three homework every night, and the situation was much better.

Learning is boring for children who don't like to learn. But everything requires you to sweat. What you say is your own problem, and if you don't make up your mind to do it, even if others tell you how to do it, it's useless.

Believe in yourself, "I can do it", and encourage yourself every day.

Relax, just imagine that you are good, and the same homework is completed within the time you set.
