"Push the earth and the mountain shake, and the lightning speed is running at will, so Zhang Yutong, you are a casual person. Then I will invite you to have ice cream, and you can eat it casually." In late April, Aries City was already hot, and Lanjie suggested going to the convenience store in the school cafeteria to enjoy the ice.

"Langjie, if I was casually cheated by you with ice cream, wouldn't it be too casual?"

"Do you go?"

"Oh, let's go, it's so hot."

Zhang Yutong and Lanjie came to the cafeteria. Lanjie bought two five-sheep crispy skins. The crispy skin of this variety is meat-filled crispy skin, not at all, and is particularly hard.

Ranger asked: "You don't have any exams in international classes, so how do you measure your academic level?"

"It's time to take the exam, June and July, computer exam." Zhang Yutong said, and she asked again: "How do you arrange the four-day holiday on May Day?"

Ranger replied: "I will participate in the long jump competition on the 30th. The 1st to 3rd will be decided. If you don't attend English classes these three days, then let's make an appointment?"

Zhang Yutong said: "I have time on No. 2, I tentatively booked No. 2?"

“No. 2 is OK.”

"Langjie, where did you compete on the day of the thirty?"

“Sports City.”

“Isn’t the Sports City Track and Field Field right next to the Sportsmen’s Village?”

"Yes, it's that track and field. Zhang Yutong, have you been there?"

"It's not just that I've been there. I'm very familiar with it. My family is in the Athlete Village."

"Huh? Zhang Yutong, don't you live in the second phase of Yueshan Coast?"

"I bought the house on Yueshan Coast later. I studied in the Sports City in elementary and junior high school."

"Yes, I remembered it. Zhang Yutong, you are the junior high school graduate of Yangtie No. 1 Middle School in Sports City."

"Anyway, it's very close. On the 30th, I went to the competition site to observe your majesty. Langjie, how did you jump long? Your jumping power is invincible, so you should also jump long, right?"

"I have been practicing for a month, and there is no big problem. Just come and observe it and it's all done."

After eating ice cream, Lanjie and Zhang Yutong farewell. He returned home and reviewed English in the most efficient way.

The next morning, I took the Science and Technology Comprehensive Classification/Literature Collection. This is the first time I took the Science and Technology Comprehensive Classification/Literature Collection in the second grade. No matter how many points the students get, the school will no longer approve the transfer of students in the second grade. Zhang Yutong and Su Zihan's transfer of classes is the last wave.

The invigilator in the examination room of Lanjie and others today is Teacher Zhao Lin. Teacher Zhao teaches English in Class 2, 3 and 2, 2, 6.

The teacher in the six main courses is the most beloved f6 by students.

Teacher Zhao Lin is the person with the highest education and the least qualifications in Class 2 and 3 F6. She was already 29 years old when she graduated from her Ph.D. She taught English in Sheep for less than three years and is a newcomer in the education industry.

After Dr. Zhao distributed the comprehensive examination paper, the students answered the questions immediately.

Langjie still quickly browsed the test paper and started answering the questions. This is a good habit, I hope to keep it.

Similar to the mathematics test paper, this comprehensive science test paper is ordinary overall, and the slightly difficult one is the physics big axle sub-question.

The explanatory materials for the physics big axle questions adopt a plain and straightforward writing style of reportage, saying that a French boy named Foo Ke, who has both good character and academic performance and is a top student.

Foucault, who had excellent grades, was admitted to the best medical school in France to study medicine. He studied medicine for several years, but found that medicine could not save the French, so he switched to studying physics.

Later facts proved that Foucault was wrong, and he could save the French by studying medicine. When Foucault wanted to return to medicine, it was already a big fuss. Foucault, in middle age, became a famous European physicist and was deeply appreciated by Napoleon III.

Foucault was elected as an academician from the French Academy of Sciences, the Royal Academy of Sciences, the Berlin Academy of Sciences, the St. Petersburg Academy of Sciences, and other academicians. He was successful and famous, leaving behind a peerless weapon called Foucault.

Please prove that the rotation period t’ of the Foucault pendulum swing plane is related to the latitude φ where the pendulum is located, and follow t’=t0/sinφ.

Mechanics questions appear very frequently, and can be said to be the type of compulsory questions with the highest frequency.

Students, don’t be bothered. Since most mechanics questions are free points, why not get a few more points?

This physics big axle problem is under the guise of Foucault, and the ones who solve the problem are actually Newton and Coriolis.

‘Brother Coriolis, you've added another show, you have a lot of scenes.’

Coriolis and Ranger are with each other. If there are any questions about Coriolis' strength, Ranger must get full marks, and commit suicide if he doesn't get full marks.

Because the earth rotates, the observer on the earth is located in a rotating system. Therefore, in addition to being subjected to gravity mg pointing to the center of the earth and pulling force t along the cycloid, the swing ball is also subjected to Coriolis force fc=-2mw×v.

Based on this set of logic, Lang Jie made a series of mathematical calculations.

The calculation process is quite complicated. Ranger takes the capital of China as an example. The latitude of our great capital is about 40 degrees. In the capital, the swing plane of the Foucault pendulum rotates for about 37 hours and 20 minutes per week, and finally it is proved that t’=t0/sinφ.

‘Brother Physics, I'm done, are you satisfied?’

‘Are you satisfied? Then I hand in the paper.’

Lanjie raised his left hand and Teacher Zhao Lin came over.

"Langjie, are you handing over the paper?" Teacher Zhao asked softly.

Langjie nodded and handed over the paper and left.

Before leaving the classroom, Ranger looked back.

Yang Kewei is still fighting hard. From Yang Kewei's hand gesture, it can be judged that Yang Kewei is drawing a picture, and it will take at least twenty to thirty minutes before the proof is completed.

In the field of physics, chemistry and biology, I, Ajie, are slightly better.

Lanjie, who handed in the paper more than an hour in advance, went straight to lunch, and after lunch, he continued to take the English exam.

To describe this English exam in one sentence, Ranger's answer is: Always choose B and always enjoy it.

Whether it was intentional or coincidental, the multiple-choice answers to this English test paper are mainly b, and the market share of b exceeds 60%.

a's market share also reached 30%, and c and d encountered an unprecedented market crisis.

bba,aab,bbba,abb.

Up and down, down and up, front and back left and right, up and down.

Once the ultimate move is activated, no one loves it!

aab,bba,bbb...

The ultimate move was connected, but Ranger was a little panicked for no reason!

There is only one c in an English test paper, which is unreasonable!

C is no longer carrying, it makes people sad and panic.

The last reading comprehension is an analytical article about the "Belt and Road" written by a professor at a European university.

This foreign scholar stood a neutral position and analyzed it with an objective attitude. He believed that the "Belt and Road" was a great strategic concept and had been put into practice. Many countries benefited from the "Belt and Road" and the world pattern had undergone subtle changes.

According to the content of the article, among the following options, the important ports of the "Belt and Road" are (multiple choice):

a,gwadar   port

b,port   of    piraeus

c,darwin    port

d,port   of    los   angeles

Don't panic.

This question is definitely ab and points will be given.

Ding Ding Ding!

carry out an assignment!

Lanjie submitted his English test paper and finished all the subjects in the midterm exam. He was absolutely sure about the results of mathematics and science. If he failed to get 445 in mathematics and science, he would commit suicide.

How many points can I get in Chinese and English? Langjie seems to be as stable as an old dog, but in fact he is a little panicked.
Chapter completed!
