met Xue Yuhang who he bumped into a few days ago in the carport, Wen Xiaoguang glanced at him, and looked at him with an embarrassed face.

I used to laugh at him for his bad grades, but now the grade rankings are out.

Smiled silently, not wanting to say anything, he half-squatted down and continued to be busy with his own business.

And Xue Yuhang didn't dare to confide in a word, he hurriedly left here, his pace accelerated, and he almost stumbled and fell, this kid forgot that the carport has steps, and the appearance of stepping on the air and twisting his waist seems to be a world-class dance move.

"The stray cats in the school, you fed them?"

A soft voice suddenly sounded a short time later.

Wen Xiaoguang turned his head to see that he was dressed in a gray windbreaker, with his hands in his pockets, standing slim, gentle and lovely.

He still likes to listen to her, her voice is soft, and it is comfortable to listen to.

"No," he continued, "there was a cat food bowl here, I don't know who put it, I think it's too dirty, and there is a lot of spoiled food that no one can deal with, so I want to change to a new one, cats can't eat that food." ”

"You like cats very much?" Mr. Wen took two steps closer to his side.

Wen Xiaoguang took away the previous cat food bowl, put his own, and slowly poured the newly bought cat food next to him.

"At most, the weather will turn cold, 60% of stray cats will not survive the winter, and it will be difficult for kittens under four months to survive. Wen Xiaoguang said headless words.

But Wen Liushu already understood.

"It's pathetic. I didn't expect you to be tall, not only are you not careless, but you are also very careful, I didn't know what you said before. ”

Wen Xiaoguang is a little blind, according to this statement, if you accidentally grow up, you have to be insulated from being careful in this life?

"By the way," she stroked her hair, "just now I told Teacher Lu that you are very serious in class, but he is a little unhappy, is he making trouble for you?"

Wen Xiaoguang was a little strange, Bald Lu suddenly appeared and said something inexplicable, listening to her say this, she could sort out the logic.

Not far away, two orange cats and a white cat came smelling and fart, they had some stains on their bodies, meowing and meowing, making people want to masturbate.

Wen Xiaoguang looked at them, his eyes were full of the urge to pet the cat, but the stray cat was too dirty, and he didn't touch it easily.

"Even if Teacher Lu makes trouble for me, isn't this a common scene in school? Teacher Wen, are you so kind?" he teased.

Wen Liushu pursed his lips and smiled, this student's way of speaking is always normal and logical, with a hint of surprise in his thinking, unlike the kind of student whose eyes are dull and have no spirituality when he reads.

She smiled and said, "Not long after I arrived, I was really afraid that my unintentional behavior would trouble others. ”

Under the autumn sun, Wen Xiaoguang was shining very warmly.

He showed a smile, "No, don't think about it, Teacher Lu didn't trouble me, he just told me a few words." ”

"By the way," Wen Xiaoguang clapped his hands, "when did Teacher Yang get sick?"

"During the exam, his lumbar spine was not very good, and he had a herniated disc in his lumbar spine. ”

"In the future, Teacher Wen will substitute for us?"

"At the moment, it is, but Mr. Yang will not always be bad. ”

Wen Xiaoguang had an idea, but he was more devilish, so he didn't say it, still hoping that Teacher Yang could try to get better.

Wen Liushu took a closer look at him, "Really didn't you feel sad because of Teacher Lu's criticism of you?"

"What's so sad about this?"

"When I was a student, the teacher said I was going to be sad. ”

Wen Xiaoguang smiled, "I don't want to be Confucius, 70 points are very satisfying, and the remaining 30 points are shortcomings, can you still let people say it?"

Wen Liushu put his hand in his pocket and smiled slightly, "I know why you write your essay well, people who love to play with words are like this, they are careful and think a lot." ”

"You mean hypocrisy, right?"

She quickly took out her hand and waved, "I didn't say anything back. ”

Wen Xiaoguang didn't misunderstand, just kidding, the three stray cats had almost eaten, and he poured the rest of the cat food into it.

Wen Liushu bent over and said, "I'm not always busy here, I can help you feed it in the future and buy some dried fish." ”

Hearing her say this, Wen Xiaoguang was startled.

"Thank you," he looked embarrassed, and quickly explained with a smile: "But don't let them eat too much small dried fish, although cats love to eat fish, but small dried fish are very rich in minerals, and eating too much is easy to get stones." ”

He's really a little afraid of people who don't understand.

It's terrible to do bad things with good intentions.

"The cats don't eat the same food as we do, especially onions, milk, chocolate and raisins, which are similar to arsenic as we do. Wen Xiaoguang looked at the three small animals and said.

"Ah?!" Wen Liushu was surprised, and was a little skeptical, not to mention anything else, can't drink milk? The cat milk that the kitten grows up to drink, one of the cat milk and milk is nutritious, and the other is poisonous? Is there a scientific basis?

"Really? I really haven't raised it, but I can't even drink milk?"

"Don't give them a drink. Wen Xiaoguang is quite serious, this kind of blindness, sweeping one may kill one less cat, "The lactose-decomposing enzyme in the cat's body is relatively small, and it will be less with age, so it will not be able to digest the lactose in the milk, resulting in lactose intolerance." ”

"Lactose intolerant?" Wen Liushu asked, raising his eyebrows.

"Hmm...... How can I say it, people can also get this disease," Wen Xiaoguang pursed his mouth, "Lactose intolerance simply means that lactose cannot be digested, which is generally caused by a decrease in lactase secretion or low activity at the tip of the villi on the surface of the small intestine, especially the jejunal mucosa,"

"Once it can't be digested, part of the lactose will be fermented into lactic acid, hydrogen, methane and carbon dioxide by the colon flora, the gas will cause flatulence, and the lactic acid will irritate the intestinal wall to cause diarrhea, and even cause osmotic diarrhea, and in severe cases, dehydration and death. ”

Wen Liushu looked at him with wide eyes and said, a little dumbfounded,

If you don't talk about anything else, she can't carry it herself. To be honest, I listened to some of it, but I didn't understand it completely, and after looking at it for a while, she suddenly laughed, this young man was a little interesting.

"But kittens also grew up drinking cat milk, so there is such a big difference between cat milk and cow's milk?"

Wen Xiaoguang answered: "Well, cat milk is high in fat, high protein and low in lactose, and milk is low in fat, low protein and high in lactose. ”

Yo, I answered.

Wen Liushu smiled at the corner of her mouth, it was the first time she had met such a person, and she was a little interested, so she tilted her head and asked, "What about onions, why can't you eat them?"

"The sulfoxide and disulfide in onions can severely damage the cat's red blood cells, and the cat is extremely anemic if it eats too much. ”

"Wait, wait, what?" Teacher Wen's eyebrows flashed quickly, she was a liberal arts student.

"Sulfoxide is a class of compounds containing thionyl functional groups. Wen Xiaoguang replied seriously.

Writing: ???

She froze in place, do all the current high school teachers teach this?

I'm sorry, that's all I have to say, I really don't understand.

With this amount of knowledge, you told me that he didn't have good grades before?
