January 1 is a statutory holiday, and employers are required to pay three times the wages of employees who attend the work.

The third grade of Jiangcheng No. 2 High School took a day off on January 1 and classes continued as usual on January 2.

Xialu's January outline is to thoroughly implement targeted poverty alleviation and win the battle against poverty.

The projects that need to be lifted out of poverty are mathematics and physics.

It is foreseeable that if Xia Lu's mathematics and physics get rid of poverty or even become rich, Xia Lu will not be far from taking off, and may be able to really take off and become a 600 + player admired by the world.

"Mathematics + Physics, Mr. Hu's requirement for me is to improve by more than 60 points, that is to say, 150 points in mathematics must be more than 100 points, and 110 points in physics must be more than 60 points. ”

Xia Lu reviewed the January outline and implemented it as planned.

The college entrance examination is getting closer and closer, the number of questions brushed is increasing day by day, and the number of times of reviewing the test center is superimposed over and over again, and the strength of most of the senior high school players must be gradually increasing.

The senior in January this year is stronger than the senior in December last year.

The problem is that when you become stronger, other people are also getting stronger, and the college entrance examination admission line is drawn proportionally.

Only if you become stronger than others can you get your wish.

Xia Lu sorted out the math problems accumulated in the recent period, and found the math teacher Wei Xiaolan during the break before the evening self-study.

Ms. Wei, who is breastfeeding, often leaves school at 7 p.m. to go home to nurse her baby girl.

Therefore, the time to ask for math problems alone is precious, and Xia Lu must race against time to learn the most practical math skills from Mr. Wei.

"Xia Lu is here. Wei Xiaolan said she had just finished tutoring a student in the next class.

"Teacher Wei, I still don't understand some math problems, I've sorted them out, you can diagnose me. ”

Xia Lu's preparations were well done, first of all, an A4 blank sheet of paper, which was clearly listed 123456...... There are 18 math test points that he finds difficult to understand.

Corresponding to these 18 test centers, Xia Lu marked 69 questions with a red pen on several practice test papers.

"Xia Lu, do you want to exhaust me?" Wei Xiaolan rubbed her temples, she was actually very tired after a day of work.

Shouting that she was tired, but her body was not relaxed, Wei Xiaolan performed the basic duties of the people's teacher, preaching, teaching, and solving doubts.

"From the 69 questions you prepared, I will pick a few of the most representative questions and tell Xia Lu about your ideas. ”

"Well, thank you, Mr. Wei!"

"This problem is very representative, Xia Lu you have to remember that the essence of linear programming is to geometry algebraic problems, and the key skill is to use the idea of combining numbers and shapes to solve problems. When you make a feasible domain accurately, and draw the straight line corresponding to the objective function, you must pay attention to compare it with the slope of the straight line in the constraints.

"I see!"

"OK, I hope you really understand. As long as you understand the principles and problem-solving skills of this type of question, no matter how x, y, and z change, and what constraints the teacher gives, you can simplify the complexity and quickly calculate the correct answer. ”

"Okay, I'll go back and think about it again. ”

"This question is also very representative, it seems that Xia Lu is on the road. Wei Xiaolan carefully looked at the topics prepared by Xia Lu, Xia Lu's organization was very clear, although he was not very good at doing these topics, he could classify these topics reasonably according to a certain law.

"Vectors can be said to run through the whole of high school mathematics, this problem seems complicated, but in fact, it is very simple to find the right method. ”

"It is easy to solve a normal vector of plane ABB1 according to the system of equations, and then solve it by using the cosine formula of the angle between AC1 and the normal vector of plane ABB1 and the coincidence relationship between the angle of the line and the surface and the angle of the vector. ”

Wei Xiaolan spoke seriously, and Xia Lu listened attentively.

Both the teacher and the student were very engaged, and an hour passed in the blink of an eye, and the hands of the wall clock pointed to seven o'clock.

Xia Lu looked up and glanced at the time, and said gratefully and apologetically: "Thank you Teacher Wei for your guidance, I have learned a lot, I should go." ”

"Don't go, it's not over yet. Wei Xiaolan wasn't happy.

"It's ten past seven, it's time for me to go. Xia Lu looked at the wall clock on the wall and kindly reminded Mr. Wei that it was time to go home to breastfeed.

There is a two-way influence between teachers and students, and students are more motivated to learn, and teachers are more passionate. The students' mud can't support the wall, the dead horses are dead, and the thorough treatment is ineffective, and most teachers don't want to care about these self-defeating students anymore.

Being a person and doing things must have a beginning and an end, and you don't let people continue to be cool halfway through, and you are in a hurry with you.

Wei Xiaolan couldn't stop talking about the topic: "After this topic is finished, you can go again." ”

Unbelievable。

Search Unbelievable.

Teacher Wei, you are the mother of the child, you have to leave here quickly and go back to feed the flowers of the motherland.

Xia Lu couldn't help but feel worried about the little public act that Teacher Wei's family was waiting to be fed.

"My BB has been arranged, after all, I am a teacher in the third year of high school, and I can't go home so early every day, who doesn't have children? You are also the precious children of your parents, so the core idea of this question is......" Wei Xiaolan dispelled Xia Lu's concerns, and then finished talking about the type of question she thought was very important.

The teachers of the senior high school graduating class are really hard, and the senior high school students go out early and return late all day in school, and the teachers are the same.

It is normal for a lactating female teacher to come and leave early, and no one will raise any objections.

Wei Xiaolan is a highly enterprising female teacher of the people, children have to be born, children have to be raised, and work cannot be delayed.

The main source of nutrition for babies before they are one year old is breast milk, and Wei Xiaolan has prepared breast milk in a bottle, and her baby's baby will not run out of milk under the care of her family.

There is no need to tell Xia Lu about this kind of parenting operation, Wei Xiaolan just told Xia Lu, my family affairs have been arranged, Xia Lu, your task is to work hard and work hard, concentrate all your firepower to improve your math scores, and meet the college entrance examination with the fullest mental state.

Xia Lu returned to the classroom and studied on his own in the evening.

Not to mention, under the careful guidance of Teacher Wei, Xia Lu suddenly gave birth to a sense of happiness that was integrated and suddenly realized.

"Construct appropriate spatial rectangular relationships and accurately solve the coordinates of relevant points. ”

"Find the normal vector of the plane, and then use the most appropriate application formula. ”

Xia Lu brushed the questions, brushed the math problems, and brushed the math problems for one night according to the various problem-solving routines formulated by Mr. Wei.

For some question types, the previous Xia Lu had to copy the answer and push it back backwards against the answer.

Now, for the same type of math problem, Xia Lu tries to derive it forward, and then answers it after finding the result.

"That's the right question!"

"That's the right question again!"

This question successfully proves the words of question 1 and question 2...... See the answer first. ”

It was impossible for Xia Lu to become invincible in mathematics in one night, and he would not be able to do those really difficult problems.

However, Xia Lu is also improving, and now he is basically free of multiple-choice questions, fill-in-the-blank questions, calculation proof questions, and can also carry out tackling problems logically according to the core ideas.
