Ranger entered a new strategic stage and he actively prepared for the preliminary round of the four major subject competitions.

On the tactical level, studying 13 hours a day is not enough. Rangera has 3 more hours. He studied 16 hours a day, and he learned to death!

The study intensity of 16 hours is too high. If you are exhausted from learning, you will fall into a short-circuited state of brain and you will not be able to learn anything. Not only will you be tired, but you will also be irritable and you will not even be able to sleep. You just want to be quiet or vent your anger.

One of the reasons why people are irritated is that they fail to complete the preset goal, and then they will be picked up by the boss, teacher, and parents. The more they are picked up, the more they become irritable, and the more they are irritable, the more they are unable to achieve the goal. The vicious cycle starts, and after a period of time, the whole person explodes.

This is a very challenging learning efficiency. A healthy and strong body is the basis for efficient learning.

Or, you don’t set goals at all, there will be no performance without goals, there will be no performance without performance, there will be no pressure, and you will be very happy.

Since Ranger sets his goals, he gets happiness by achieving them.

Although she is busy with her studies, Ranger did not give up physical exercise, and she must ensure that she exercises for at least 10 hours a week.

After exercise, Ranjie has a very high learning efficiency. He usually does five questions in an hour, and after exercise, Ranjie does ten questions in an hour!

With Beethoven and Mahler's assists, Ranger can do fifteen competition-level puzzles in an hour, and they are all right!

If you drink a little more sauce-flavored liquor...

Inspiration explodes!

Invincible in an instant!

Everyone has different ways to improve their learning efficiency. The most important thing is to use solid and solid basic knowledge as the cornerstone. If the knowledge base is not solid enough, no matter how fancy it is, it will be useless.

The accumulation of knowledge is not a matter of time. In the past decade, Ranjie believes that he has accumulated enough basic knowledge, and what he is doing now is to strengthen his skills.

strengthen!

strengthen!

strengthen!

On the evening of September 6, while Ranger received a medal of honor, he added abstract thinking!

At this time, Ranger was listening to Mendelssohn's "Song of Spring".

The melody of "Song of Spring" is graceful and melodious, which helps sleep.

This song is very specific, why did Ajie's abstract thinking be added?

Ranger was puzzled, so he could only forcefully explain: Mendelssohn and his musical works had certain hidden attributes, and this hidden attribute could stimulate abstract thinking?

A more reasonable explanation is that no thinking can add one in just a few minutes. The abstract thinking at this moment adds one because Ajie has completed high-intensity learning in the past one or two weeks. In the short period of system settlement, Ajie happened to be listening to "Song of Spring".

Regardless, listening to classical music is a good habit, I hope to keep it.

On September 7, Ranger got up at 5 o'clock as usual.

The first thing I do after getting up is to pay homage to my elder brother.

‘Brother Physics, good morning.’

‘Last day, I failed, I lost a crushing defeat.’

‘The most painful thing in the world is that I could have.’

‘Today this year, I, Ajie, took the stage again, and started again where I failed.’

‘I’m not fighting for this to get back what I lost with my own hands.’

‘But to prove that I, Ajie, are amazing.’

‘Brother Physics, please bless me to turn bad luck into good fortune and physics is invincible.’

‘Kowtow! Kowtow! Kowtow!’

After paying homage to his elder brother, Ranjie was extremely relieved. He ate 70% full for breakfast, and after the meal, he brewed a pot of coffee, adding sugar but not milk.

Because of the effect, Ranger will not get sleepy throughout the day.

He had the habit of drinking coffee. Drinking a cup of coffee in the morning will make this morning as familiar as usual.

After tasting the coffee, Lanjie brought the admission ticket and answering tools to the Yueshan District Examination Center.

In the preliminary competition of the physics competition, the middle school students who signed up for the sheep went to the examination room on their own. Many students who Lanjie knew signed up for this year's cpho. There were double-digit students who participated in the preliminary competition of the cpho at the Yueshan District Examination Center.

"Hey, Zihan!" On the second floor of the No. 1 Examination Building, Lanjie met Wu Zihan.

"Hey, Brother Jie!" Wu Zihan was full of fighting spirit. The T-shirt he was wearing was made of ordinary material, but the pattern on his chest was unique.

The pattern of Wu Zihan's T-shirt is: 200.

Lanjie asked with interest: "Where did you buy this T-shirt? Is it customized?"

Wu Zihan nodded and said, "Yes, it's customized online, so it's auspicious."

Ranger touched Wu Zihan's chest 200: "Zihan, you are so thoughtful, I also have some magic power, don't you mind?"

"Brother Jie, you touched it, so what can I do..." Wu Zihan covered 200, and then said passionately: "Come on, Brother Jie, we will fight side by side in the rematch, the national competition!"

"It's a must! Zihan, come on too!"

The two of them parted ways and went to their own classrooms.

Langjie was divided into classroom 202. There were 25 contestants in this classroom, and Lanjie didn't know any of the other 24 contestants.

At a few points, the two invigilators began to distribute the preliminary examination papers.

Ranger participated in a preliminary cpho competition and he was familiar with the competition rules.

The cpho preliminary round is full of theoretical questions, with a total of 200 points, and the exam time is 9:00 to 12:00.

Langjie got the test paper, and there were still dozens of seconds left before 9 o'clock. Langjie quickly browsed the test paper, and this year's preliminary test paper still had 16 questions and 200 points.

‘No big problem!’

Lanjie made a rough assessment of this test paper.

In the Cpho preliminary round at this time last year, Ranger took the game while he was ill, which affected his performance. He only scored more than 80 points and missed the rematch.

Today, Ranjie is not sick or injured. His physical and mental state are full. This is the best Ajie, and this is the most powerful Ajie!

Ding Ding Ding!

The ringtone rang and the exam started!

1. Multiple choices. There are 5 questions in this question, and each question has 6 points. Among the four options in each question, some questions only have one of the questions in line with the meaning of the question, and some questions have multiple questions in line with the meaning of the question. If you choose the correct option, you will get 6 points. If you choose the wrong choice or missed choice, you will get 0 points.

1.1. As shown in the figure, there is a 60mm mercury column in a straight glass tube with a closed end and an opening at the same end. When the tube is placed horizontally to balance, the air column in the closed end A tube is 140mm long, and the air column in the starting end B tube is also 140mm long. Now gently reverse the tube, so that the opening is downward, and then vertically insert it into the mercury tank. When the equilibrium reaches equilibrium, the air column in the closed end A tube in the middle is 133mm long. Assume that the atmospheric pressure is 760mmhg and the temperature remains unchanged, the height h of the mercury in the groove enters the tube:

a,42mm;

b,34mm;

c,28mm;

d,16mm.

‘Obviously, this question is a single choice.’

‘What to choose?’

‘Let me calculate it.’

Lanjie can't remember how many questions he has tried, but there are not ten thousand, and there are eight thousand.

Although Ranger has never seen the same question, he knows that the principles of this type of question are similar.

Be confident, remove the word similar and change it to the same.
Chapter completed!
