The harvest is harvested, the planting is also planted, in the blink of an eye to the grain to the warehouse, firewood to the stacks of the slack season, do not dig ditches do not dig the river, very idle, except for a few strong laborers go out to find some work to do, most of the personnel are idle at home, not a few people together to play cards to kill time, or gather in a piece of gourd and gourd west scoop scoop nonsense, no serious words; There are nosy people who say that people are long and short, and they are either questioned one after another, or they are pointed at their noses and scolded for a dog's blood spray, shrinking into a turtle and not daring to answer; Bad luck and bad luck, the gambling man gives the hard-earned money earned by himself and his wife to others to spend, loses it and steals it from home and is found, lowers his head and lets his wife and family count it, and swears to quit gambling from now on, but once he gets out of his body, he becomes nowhere and cannot be found. In contrast, women are much more secure than men. At home, they dismantle, wash, sew and mend, change what should be changed, change what should be set, beat paste and wipe the jackets, make shoes for adults and children, and carry firewood to cook. Of course, there are also women who talk nonsense: who is frowning at whom, who is eyebrow-raising, who is watching the autumn waves, which man goes to which woman's house when her man is not at home...... Speculating, doubting, waiting for the truth to emerge. A bunch of women were dispelled by a woman's rumors: the person who was afraid of involving herself left, the person who was afraid of asking the rumors left, the person who was afraid of setting herself on fire left, and the woman who believed it was true was the last to leave.

Qin Zhongzhong was not among these men, and Han Furong was not one of these women. They are taking advantage of this rare time, racing against the clock, day and night to do what they have to do. In the era when rebellion is justified, smashing and looting becomes a hero, and handing in blank papers is glorious, do teachers dare to boldly manage students to make them pay their homework on time? It's good not to pull out the teachers and wear high hats to criticize the streets during class time, but how can there be a chance for teachers to check which student can and can't master it? The involuntary "stinky old nine" can talk about it, and if it can't be said, it won't be said; Students' homework will be corrected when they are handed in, and they will not be corrected if they are not handed in; In the face of the students' barren studies, they are just heartbroken, but they can't help it, they can only sigh with sadness and hope. In that era, in an era when the more knowledge became more reactionary, it is conceivable who could learn how much knowledge from books. Qin Zhongzhong and Han Furong know the Tao of the Road, they know and master too little, they must start from elementary school, master the most basic knowledge, and then gnaw the knowledge of junior high school and high school little by little, starting from example questions and gradually going deeper; From easy to difficult, from simple to complex, from simple to complex; which problem is solved by what method; Which question contains what knowledge and which formula can be used to solve it; how to solve the equation of several elements; chemical reactions, how the substances change before and after the reaction, what is generated, and how they are represented by element symbols; How do I use formulas to find the answer...... Everything has a pattern, and there are different changes. They didn't have the luxury of coming up with a Goldbach conjecture where one plus one is greater than two or less than two, and the knowledge in the books of junior high and high school alone made them frown and scratch their ears and cheeks. Learning, concentrating on learning, wanting to really learn some knowledge, learners who master knowledge, for them, learning is not the comfort and leisure of the wind does not hit the head, the rain does not hit the face, but the pain of not being able to find the answer in the confusion, Qin Zhongzhong and his wife are so hard to learn, gnaw, like gnawing stones, gnawing iron, sometimes leaving a tooth mark, sometimes not even a tooth mark, difficult and difficult, disappointed and dazed.

Compared with Qin Zhongzhong, Cherry's learning is better, not because Cherry is a little bit good and naturally intelligent, but because Huzi is familiar with the road and condescending and carefully guided.

"I know the degree of these two angles, what is the degree of that angle?" Huzi pointed to the figure and said that the known conditions prompted Cherry said.

"30 degrees!" Cherry thought for a moment and said.

"For what?" Huzi asked.

"Because the sum of the internal angles of the triangle is equal to 180 degrees, and it is known that an angle is 90 degrees and an angle is 60 degrees, then the degree of this angle is equal to 180 degrees minus 90 degrees, and then subtracting 60 degrees, which is equal to 30 degrees." Cherry analyzed.

"Yes, the right idea. According to the sum of the inner angles of the triangle is 180 degrees, the degree of this angle is known under the condition that the other two angles are known. So what's next? What are you looking for? Huzi let Cherry speak for herself.

"It's the area of a circle." Cherry said.

"What is the formula for the area of a circle?" Huzi asked.

“πR2。” Cherry said.

"Let's put it into a formula." Huzi said.

"I don't know the radius R, how do you calculate it?" Cherry asked, looking at her husband.

"Find a way to figure out what the radius is!" Huzi said, "If you don't know the radius of the road, you want to calculate the area, is it possible?" Must foretell the radius of the path! ”

"Radius? Radius? What is the radius? Cherry pondered, suddenly recalled the Pythagorean theorem, and said, "I know the way!" Zhilu Dao! ”

"Tell me about it." Huzi said.

"Listen to a fart! The number of the product of right angles is equal to the sum of the products of two acute angles, the Pythagorean theorem! I calculated it, and if I knew the radius, I knew the area of the circle. Cherry was quick to answer.

"is the square of the opposite side of the right angle equal to the sum of the squares of the opposite side of the two acute angles!" Huzi corrected Cherry's statement.

"Yes. My husband! Cherry stood up and kissed her husband as if she were grateful, "Thank you for taking the trouble to tutor me." ”

"There is a lot of progress, there is a lot of hope, so let's do it!" Huzi said to Cherry, "I'm going to work, I'll tell you after work." ”

"Go ahead. I'll try to do it myself, and I really can't think of it, so I'll beg you. Cherry urged her husband to say, "Go to work quickly, it's better to go early than late, and being late gives a bad impression." ”

"When you're tired, take a break, don't get too tired, see how thin you are!" Huzi confessed distressedly.

"I know. Isn't it more beautiful to be slimmer and slimmer a little thinner? Cherry said casually.

"I like your natural beauty, not your slenderness." Huzi walked out of the hall and said.

"Okay, I'll eat more, I look like a fat pig, see if you're annoyed!" Cherry said.

"I like it when I can get fat like a sow!" Huzi walked back and said.

"That's the case, it's even uglier than Zhu Bajie!" Cherry said, "I haven't been here this month, can I still be pregnant?" ”

"Did anything else react?" Huzi asked.

"I just don't want to eat very much, sometimes I want to vomit, I can eat some sour to change the taste, I don't know if it will be better." Cherry said in discomfort, her stomach rolling, her mouth burping, and vomiting.

"Good! The seeds of our love are beginning to take root! Huzi said happily, "You wait, I'll go buy you sour." Huzi ran out of the door.

"Child, if you don't come at the right time, you will ruin your mother!" Cherry said in her heart.

After a while, Huzi brought a large bag of fruit into the door and said to his wife, "Here, grapes, oranges, apples, pears, everything." ”

"I just have a little feeling, casually saying this, who let you buy it! Lang costs money! "Cherry blames Huzi.

"Yes, not Lang fee." Huzi sat on the bed with cherry and said, "As a husband and father, it is my responsibility to take care of my wife and children. ”

"No, I have to learn, I can't give up halfway!" Cherry picked up the pen again and worked on the topic.

"Let's learn, it's good and harmless anyway." Huzi said, "Be sure to take more rest!" ”

"Zhilu Dao!" Cherry said to her husband who went to work.

She worked tirelessly, and as the fetus grew, she also put knowledge into her heart and engraved it in her mind.
