Knowledge and Practice

It was a 13-year-old junior high school student—a bean sprout as small as a bean sprout. At this age, he was already a big child in the orphanage.Sitting next to Xiao Xingyi were children who were slightly younger than him. Some of these children looked no different from ordinary children, while others could clearly see that their eyes were slightly wider than ordinary people. Some small manual work will be provided for these children to do, and the children next to them will have different degrees of repetitive and slow movements, but these clumsy behaviors have not been seen in Xiao Xingyi.

Soon, Xiao Xingyi finished the task of stringing beads and started to do the homework assigned by the school.

Xie An walked in to look at his book, a scientific problem - write down the complete metamorphosis of frogs and the incomplete metamorphosis of locusts.

Xiao Xing filled in all the things he could do before, but this question was left blank, and he looked very troubled while biting his pen in a daze. It seemed that animals and insects were indeed beyond the scope of this child's understanding.

Xie An looked at the topic carefully, and found that it was indeed not easy. The current junior high school science is not so easy to understand even from the perspective of a graduate student who has been working for several years. He stroked his thoughts, and after a while, he gently asked Xiao Xingyi agreed: "Do you need my help? I just read this question."

He was patiently waiting for Xiao Xingyi to respond, Xiao Xingyi looked at him, blinked, did not speak, and just handed him the pen.

He was a well-mannered little boy. Xie An had a good first impression of him, and then he began to give him lectures.

"First of all, we need to clarify the difference between complete allergy and incomplete allergy."

"Like a frog, from fertilized eggs, to tadpoles, to young frogs, to adult frogs, do you see any changes in her living habits?"

Xiao Xing nodded, continued to look at Xie An, and motioned for him to continue.

Xie An was not discouraged by Xiao Xingyi's habit of not answering, and continued to finish the following patiently, "You see, it used to swim in the water, but later it crawled on land. It was originally a tail , Now there are many legs, this means that the living habits and body shape have undergone great changes, so we call this kind of great change complete metamorphosis."

"The metamorphosis here refers to the form and living habits."

"And what about the locusts next? Tell me what the locusts were like when they were kids?"

Interacting with children is probably the talent and mission of pediatricians. Xie An tirelessly asked questions and patiently waited for Xiao Xingyi's response.

Xiao Xing shook his head, expressing that he did not know

Xie An persisted, "Then I'll show you a drawing. Xie An drew a larger locust and a smaller locust on the paper."

Then he pointed to them and asked, "Which one do you think is when he was a child?"

Xiao Xing looked at the picture, cherishing the words like gold, ordered the smaller one, and said, "This one."

"That's right, this is what locusts looked like when they were young. Small locusts and big locusts are different in size, living habits, and body shape. This kind of development is called incomplete metamorphosis. The development process of locusts is fertilization. The process of egg, larva, and adult, do you understand?"

Xiao Xing nodded, Xie An looked at him contentedly, probably because the act of teaching and educating people is easy to inexplicably have a sense of responsibility, and after that, he finished tutoring Xiao Xingyi's science homework by the way, so he was reluctant to part go back.

Before leaving, Xie An specifically asked about Xiao Xingyi here.

He was patiently waiting for Xiao Xingyi to respond, Xiao Xingyi looked at him, blinked, did not speak, and handed him the pen docilely.

He was a well-mannered little boy. Xie An had a good first impression of him, and then he began to give him lectures.

"First of all, we need to clarify the difference between complete allergy and incomplete allergy."

"Like a frog, from fertilized eggs, to tadpoles, to young frogs, to adult frogs, do you see any changes in her living habits?"

Xiao Xing nodded, continued to look at Xie An, motioned for him to continue

This child doesn't seem to like talking, Xie An thought so, and continued to finish the following patiently, "You see, it used to swim in the water, but later it crawled on land. It used to be a tail, but now it has a tail. There are a lot of legs, which means that the living habits and body shape have changed a lot, so we call this kind of big change a complete metamorphosis."

"The metamorphosis here refers to the form and living habits."

"And what about the locusts next? Tell me what the locusts were like when they were kids?"

Xie An just wanted to hear Xiao Xingyi interact. He also liked interacting with children when he was a doctor, and it is the same here now.

Xiao Xing shook his head, expressing that he did not know

Xie An persisted, "Then I'll show you a drawing. Xie An drew a larger locust and a smaller locust on the paper."

Then he pointed to them and asked, "Which one do you think is when he was a child?"

Xiao Xing looked at the picture, cherishing the words like gold, ordered the smaller one, and said, "This one."

"That's right, this is what locusts looked like when they were young. Small locusts and big locusts are different in size, living habits, and body shape. This kind of development is called incomplete metamorphosis. The development process of locusts is fertilization. The process of egg, larva, and adult, do you understand?"

Xiao Xing nodded, and Xie An looked at him contentedly, probably because the act of teaching and educating people is easy to inexplicably have a sense of responsibility, after that, by the way, he finished tutoring Xiao Xingyi's science homework, so he didn't I can't go back.

Before leaving, Xie An specifically asked about Xiao Xingyi here.

When the child was sent to the orphanage, he was very young. At that time, he was found to have asthma and severe pneumonia. I don’t know how the previous parents raised him. When he was found on the side of the road, he was already out of breath. What information stays, and it's still a boy.

Although pneumonia and asthma in infants and young children are protracted, they are not difficult to treat, and it is not a problem to pay more attention. I really can't think of the idea of ​​parents who abandon their children because of this disease.

Asthma in early childhood is sometimes due to incomplete development of the respiratory tract, and some children will get better when they are older.

However, it was probably because Xiao Xing's appearance of being ill when he was young was too scary. Most of the couples who wanted to adopt a child saw him wheezing and suffocating, so they gave up the idea.

As I grew older, the number of asthma attacks gradually stabilized, time passed quickly, and the child was already 13 years old in a blink of an eye, and the 13-year-old child had new problems to face, whether to raise it or not—has become a concern for the adoptive family one.

28-year-old Xie An is a pediatrician, so he knows that the child is indeed getting better. The disease is just a fluctuating process, and the child itself should not be judged so much.

The Xiao Xingyi he saw in his eyes was purely a quiet and somewhat introverted child.
