Chapter 279 The Old Man's Regret

Lin Hong still has a good understanding of the current international wireless LAN communication. Basically, it is mainly infrared wireless. The protocol used is still based on his protocol.

As far as he knows, an organization called the ieee802 Standardization Committee has set up an ieee802.11wlan standard working group and is working on the development of the ieee802.11 standard. The other name of this standard is wi-fi.

However, in Lin Hong's view, this so-called standard protocol is also inexcluded from the infrared wireless protocol he specified before. The principle is similar in essence, and the speed is not much faster.

And the wireless vortex information transmission he now imagines is likely to increase the transmission rate by at least ten times or even a hundred times more on the original basis!

Lin Hong has no idea about the specific technical parameters now. He only has a vague idea for the time being, and he must further study and improve the relevant theories.

When Lin Hong was thinking about what technical operations were needed to distort and modulate these signals, the bell rang after class.

"That's all for today." The old man did not have the habit of procrastinating. When he heard the bell ring, he immediately ended the explanation.

When he walked to the door, he suddenly stopped and turned around and said, "That... new classmate, come to my office."

After saying that, he left the classroom. The old man saw Lin Hong for the first time and didn't know his name.

When he left, the whole class suddenly became lively.

"Lin Jiang, are you still here? The old man asked you to go."

Seeing that Lin Hong was still sitting on his chin, Lu Lei couldn't help reminding him kindly.

"Huh? What's the matter?" Only then did Lin Hong recover from his thinking.

"How do I know what's going on? Maybe it's because of the finale. You'd better hurry up. He doesn't like others to be late, and he still has a hot temper.

Then Lin Hong asked Lu Lei about the general situation of the old man. After thanking him, Lin Hong came to the old man's office.

"Coming." The old man is waiting for his arrival, "Your name is Lin Jiang? Is it Mr. Feng's relative?

He has just learned a little about Lin Hong from the head teacher of Class 287.

"Yes." Lin Hong nodded.

"You have a good math foundation. Where did you study before?"

"In J province."

Lin Hong answered truthfully according to the information on his file. His new identity, in order to be able to cope with the investigation of some people with intention, is also relatively reasonable, and ordinary people really can't find anything.

The old man didn't care about this, and then said, "Have you done these two questions before?"

At this time, Lin Hong realized that the old man called him to come because he answered the questions too smoothly and attracted his attention.

However, Lin Hong did not intend to hide anything this time. He had made up his mind to be admitted to Shuimu University, so he said, "No. It's the first time I've seen this type of question.

"Oh?" The old man's eyes lit up.

He thought for a moment, took out a test paper from the drawer, and then pointed to the last two questions and said, "Let's see if these two questions can be done?"

Lin Hong took the test paper, looked at it for a moment, then picked up a pen on the table, and answered it a few times.

The old man took it over for a while, and then praised: "The problem-solving ideas are exquisite and concise, wonderful!"

The method used by Lin Hong is once again very concise, and many steps are omitted in the middle. This method can only be done by those who are very familiar with mathematics and know it.

The old man looked at Lin Hong and nodded with a smile: "That's good! However, I still want to remind you that although this kind of problem solving is usually correct, there is still a risk of deducting points in the college entrance examination. You should write down the inference steps implied in the middle..."

The old man took the pen, added a few steps in the middle, and then let Lin Hong have a look.

Lin Hong nodded to show his understanding. In his opinion, these steps are obvious, but since it is necessary for the exam, it is okay to write more words.

Then the old man asked him to do a few more questions. This time, Lin Hong's problem-solving process was normal, and the old man nodded repeatedly.

The old man regretted that Lin Hong did not turn around earlier. The more he looked at Lin Hong, the more satisfied he became.

"Here are the papers of several mock exams in the last semester. You can take them back and do them well. If you have any questions, you can ask me at any time." The old man took out another stack of test papers and handed them to Lin Hong.

After Lin Hong thanked him, he left.

"Hey hey, it seems that the first student in mathematics this age will appear in my class again!" The old man looked at Lin Hong's back and smiled.

He has felt very aggrieved for the whole year, because in the two classes he taught, no student's mathematics is an outstanding type. The highest score in every math exam is not in his class. You know, in previous years, the highest score in the math exam came from his class, which made him feel that It's a pity. Although he has found several promising seedlings for key training, they are diligent enough, but unfortunately they lack a little talent. As long as the difficulty of the test questions is raised, they will be thrown far away by others.

Now, in the last month, I didn't expect to transfer to a student with very good mathematical talent, which made me a little happy. His continuous unbeaten glorious record will continue to be maintained. Lin Hong naturally did not know that he had been included in the teacher's key training plan. He took The test paper returned to the seat and then began to answer.

He also realized that his problem-solving habits may not be suitable for the current examination system. Although he feels bored, he must adapt to these rules, otherwise he will definitely not be able to get a high score and then be admitted to Shuimu University.

Each field has its own rules. If you can't become a rule maker or rule disruptor in this field, you must abide by these rules if you want to achieve some success in this field.

Lin Hong's speed of solving the problem is amazing. He basically didn't change it. He did it all the way, not even needed the manuscript paper. He did these questions, as if he were doing the oral arithmetic questions of primary school students at a glance, passing all the way without any pause.

After finishing a test paper, he was too lazy to write again. He directly picked up other test papers and quickly scanned them. When he saw different types of test questions, he would take some time to think about it. Otherwise, he would skip it directly and no longer waste extra time on it.

I have to say that mathematics is Lin Hong's strength. In this subject, Lin Hong has no problem with the college entrance examination at all. He mainly pays attention to the problem-solving steps of solving the questions, and believes that it is completely possible to get a full score.

Lin Hong was not familiar with the school at the beginning, so in most cases, he was observing and rarely communicated with others. The one who talked to him the most was Lu Lei, who was in the same corridor from him. But this guy is a talker. Once he opens the chattel, he will keep talking. When Lin Hong is usually free, he is absolutely unwilling to take the initiative to provoke him.

When receiving the textbook, Lin Hong also received a student recharge meal card. The principle is similar to those cards in public telephone booths. There is an ic chip that can store data, which can be read and written simply through the card reader, so as to increase and decrease the value.

After the third class, Lin Hong followed the tide of other students to the school canteen.

The canteen is in the innermost part of the school, which is the upstairs where he went to the Academic Affairs Office before, and he had to walk a long distance.

Lin Hong noticed that as soon as the class was over, many people ran to the breakfast hall at a speed of almost 100 meters. At first, he was still curious about the phenomenon and guessed the reason why they were so positive. Later, he learned that they were in order to be at the forefront of the queue, so as not to waste precious time.

After lunch, Lin Hong wandered around the campus. When he came to the basketball court, he didn't want to see an acquaintance in the cement auditorium.

He also confirmed again and again to finally determine that this person is someone he knows. Lin Hong hesitated for a moment, thought again and again, and then walked over to say hello to the other party.

"Little fat."

A fat man with a figure of about 1.65 meters, but his whole body is extremely fat. The fat man in the shape of a spindle body was stunned when he heard the words.

Today, few people call themselves that way. At present, people usually call themselves "big fat".

He turned his head to look at the other party and found that he didn't know him. He couldn't help wondering, "Who are you?"

Compared with the past, Lin Hong has changed a lot. He is simply different from each other. He is not a close relative, and he can't recognize him at a glance.

Lin Hong smiled and said, "I'm your old friend. I've played Apple game console together before. Have you forgotten? Isn't your game hall open?

Pan Pan was completely stunned. After a long time, he whispered uncertainly, "Are you Lin Hong?"

Lin Hong nodded and sat down beside him.

"I changed my name. At present, my name is Lin Jiang. I just transferred to No. 1 Middle School. I didn't expect you to study here."

"I'm a straw, isn't it? Is it really you?" Pan Pan's body paused, and the fat all over his body trembled.

"Of course it's me. Wuzi also mentioned you to me a few days ago, saying that you are fatter than before. I didn't expect it to be like this. It's time for you to lose weight. Lin Hong held the fat on his stomach and shook it twice.

Pan Pan heard the words, where is there any doubt? He directly hugged Lin Hong and hugged him a few times.

Although Pan Pan has nothing to do with Lin Hong, he has something to do with Sun Wu intermittently. The two play games, drink and talk the most about the topics together, but it is still Lin Hong. Although they have been together for a short time, they have known each other for a long time.
