"All organisms on the earth basically share the same set of genetic codons, and the different arrangements and expressions of genetic codons determine the different morphology, structure and physiological functions of various organisms..." The biology teacher is still proud of the class she taught, and the biology teacher is still proud of the class she taught, because in a recent test, the class she led had three perfect scores in biology.

Approaching the college entrance examination, it seems that everyone is listening carefully to the class, even if everyone has listened to those knowledge points hundreds of times, the students are still taking notes seriously, for fear that it will appear in the college entrance examination, and they can't remember it. Even the fat man, who usually sleeps, reluctantly opens his eyelids and looks at the teacher like a pug, and no one knows if he can listen.

There was only one person, and he kept looking out the window with his slightly curled oblique bangs. At that time, it was popular for boys to have oblique bangs, and I don't know if it was a Korean tide or a Japanese trend, and many boys liked to have that hairstyle. In fact, there is nothing to see outside the window, there are no beautiful women, and it is still raining densely, but he just thinks that the class is boring, and he will be hypnotized if he listens carefully.

His grades were not excellent, even in his class he was only average, and it was not easy to get into a good university. But he also thought about getting into a good university, but he didn't seem to be able to do anything, and although he tried hard, deep down he kept rejecting this rote education. In fact, many things are the same, and if you don't want to learn anything, you can't learn anything.

His name is Lan Tianzuo, the name Tianzuo is rare, because it is a bit awkward, but there are many people called Tianyou, and there are many people called Tianyou in the "Foreign Daughter-in-law Local Lang", and there happens to be an anchor who is also called Tianyou, but it is not to the extent of rotten streets. This is not Tianzuo is the most familiar, because his brother's name is Tianyou, maybe it is to match his brother's name, he was named Tianzuo.

"Lan Tianzuo, are you in a daze again? Do you understand what I'm talking about? The biology teacher pushed his glasses, put down the book in his hand, and looked at Lan Tianzuo like this.

"Hey, what did the teacher call you, why are you still in a daze? I choose the second one for this question. The fat man next to him pushed Lan Tianzuo. In fact, the fat man had just been woken up by the teacher's voice, and he wanted to hold out this class, but he couldn't help but doze off when he listened.

The fat man is Tianzuo's tablemate, his name is Pan Key, and everyone calls him Keyboard, but he is not as slim as a keyboard at all, but as round as a mouse.

Because of the push of the keyboard, Lan Tianzuo woke up from his own world and stood up, and said hesitantly: "That, teacher, choose the second one for this question." Thankfully, the keyboard said the answer, otherwise he really didn't know what the situation was.

But to his surprise, the whole class laughed, especially the keyboard next to him laughed the loudest. That's when Tenzo felt that something was wrong.

"I'm sorry, teacher, I didn't hear you clearly, can you say the question again?" Tenzo scratched his head and looked at the teacher a little embarrassed.

"I said why are you distracted, and choose the second one, do you think you are Zhu Xiaofei's classmate? I know you're a little clever, but aren't you good at exams because of your cleverness? I only got a 59 in this biology exam, how did you do it? "The biology teacher simply stopped class, and everyone's eyes were on Tianzuo.

It is worth mentioning that classmate Zhu Xiaofei, everyone secretly calls her Zhu Xiaofei. She is a person who is recognized by the teacher as being able to sleep in class, because every time the teacher wakes her up, she can answer the questions accurately, and the test score is good, and then the teacher simply does not call her and lets her sleep. Her classmates all talked about whether she studied all night at night and slept in class, and gave her the title of the god of sleep.

"I don't seem to have scribbled the answer sheet..." Tianzuo whispered, and after saying that, he shifted his gaze to the keyboard and glared at him fiercely.

"They are all people who have passed the college entrance examination, and they are still so careless. If you can't get into a good university, you want to come back and repeat it, but you don't take it seriously, and you can't get into a good university, and you waste your youth, is it worth it? It's a waste of everyone's time, so sit down and listen carefully to the lecture and don't be in a daze. "In fact, the biology teacher is not a fierce person, but will criticize you a few words when you make a mistake and tell you about the principles of life.

In fact, most of the words are for everyone, because this class is the only repeater class in the school, and there are people of all levels, some of the powerful ones have full scores, and some of the garbage ones are almost on the verge of passing like keyboards. Usually Tianzuo can be at the upper middle level, and forgetting to fill in the answer sheet is also an accident.

Originally, Tianzuo wanted to "educate" the keyboard after sitting down, but the teacher always stared at Tianzuo's side, so Tianzuo could only step on the keyboard hard and give up. In fact, the keyboard and Tianzuo are good brothers from childhood to adulthood.,Because they live closer.,So I played together when I was a child.,I never left this county.,So the relationship is very good.,Usually they will pit each other.,It's not going to turn your face.。

The keyboard held back the pain, didn't shout, and quietly asked, "What's wrong with you?" In fact, in the heart of the keyboard, although Tianzuo's appearance has changed a little bit, Tianzuo was still short and thin in junior high school, and Tianzuo has only become "healthy" since high school. The so-called health means that he has grown taller, not as skinny as before, and his appearance has become handsome, but he is still like a child with a heart, and he will never open his heart to others. On the surface, he seems to be a little energetic and can talk and laugh with the keyboard, but sometimes he seems to be cut off from the world.

"What's wrong?"

"I said you're in a daze again."

"It's okay, I feel a little sleepy after listening to the class, so I just look at the scenery outside. It's like you can sleep like a pig. "It just so happens that Tianzuo is sitting near the window, so you can see the exterior view.

"I'll you, I wouldn't have woken you up if I knew it."

"Yes, you told me to get up and tell jokes. Choose the second one, you think you are Zhu Xiaofei's possession. ”

"I didn't know, when I woke up, I heard a voice nearby saying to choose the second one, and I told you."

"Cut." Tianzuo looked around, there were gods sitting around, but when he saw that person, he was bored, that person was called Shen Nan, and everyone called him (Nan Shen) male god. He and his table mates were still snickering silently, presumably telling the keyboard that he was the one who chose the second one.

Shen Nan looks down on all the boys, including him at the same table, in fact, he is also a horse boy at the same table. But Shen Nan is a gentleman in front of girls, in the eyes of many girls, he is a rich and handsome, personable, and rich family, but he is not the richest one.

"Li Sicong, you answer this question." The teacher seemed to see something.

Li Sicong, who was still teasing the girl next door, stood up, he didn't know the topic, but he wouldn't be like Keyboard and Tianzuo, standing up and asking to sit down if he couldn't say a word. He loves face, so he has turned to others for help, and Zhu Xiaofei behind him woke up from his sleep and whispered the answer to Li Sicong as soon as he saw the question. Of course, Li Sicong said the correct answer out loud.

"You've been fooled by this, so tell me why."

Li Sicong scratched his head and pretended to think, but he was actually delaying time, Zhu Xiaofei had already passed the analysis to Sicong's desk through Li Sicong's table. As long as Sicong reads it, he can say the correct analysis.

The teacher didn't deliberately make things difficult for him, so he sat him down. In fact, except for the teacher, all the students knew that Li Sicong had been using this trick all along, and he signed a "contract" with the god of sleep. As long as the god of sleep helps him, the god of sleep will be wrapped in his food this month. Because he is the richest person in this class, and even in this school. For him, these food expenses are just the money for snacks, and he doesn't care at all, all he cares about is face, posture and girls. Because he has the same name as his national husband, everyone calls him Husband Li, because it is a bit taboo to call his husband, so he added his surname in front, which is more interesting.

After Li's husband sat down, he continued to harass the girl next door. Although it was next door, it was also separated by a small road, and the girl ignored him, allowing him to whisper to herself. This girl is the goddess of the class, Zhang Yanran.

It is natural for her face to be beautiful, and other girls in this period will have pimples on their faces, but she doesn't, I don't know what the secret recipe is, maybe it's because the family conditions are good or she takes good care of herself. The figure is also tall, more than one meter six, and it is considered tall in the county, but no one likes it if it is too tall.

Her loose hair was draped over her shoulders, and the ends of the pear blossom curls exuded the fragrance of jasmine, but in front of her were Qi bangs, almost covering her eyebrows. Although she was wearing a school uniform, she did not hide her own nobility, but there was a trace of coldness in her nobility, yes, the goddess of coldness was her title.

She was transferred, but there are many suitors, it is estimated that a boy will like her, of course, including Tianzuo and the keyboard, but only Shen Nan and Li's husband dare to chase her. It's not so much that they don't dare, it's better to say that the others were intimidated by Li Sicong and Shen Nan.

Shen Nan is not afraid of Li Sicong, although he knows that Li Sicong is a local tyrant, but Shen Nan's background is not bad.

Tianzuo would occasionally talk to her, because he teased her at the beginning of the school year, so the two knew each other, but Tianzuo didn't think about chasing her, because Tianzuo knew that they were not people of the same level at all.

In fact, for Tianzuo, such days are also pleasant. Although it was a repetition, I also met a lot of people I didn't know before, but I didn't feel so lonely. But he was afraid that he would fail the college entrance examination again, but he didn't care about it, because he didn't want to stay on such a campus. He was afraid of disappointing those who cared about him, such as his uncle and his brother.

His brother is a genius, but he is so mediocre, he also tried to catch up with his brother, but he couldn't reach it. It's not so much about living in someone else's world, he never seems to have really lived for himself, this kind of life is not what he wants, but what he wants, even he doesn't know, this is the loneliness from the heart. Maybe it's because he grew up in a family that depended on his brother, which couldn't be eliminated and couldn't be weakened.

Even if he can pretend to smile in front of others, once he is alone, that loneliness will inexplicably come to his heart.
