Everyone was eating and drinking happily, Li Liang went to the kitchen to make noodles and brought them up, beckoning everyone to eat noodles. While eating and drinking, Li Liang's sister Li Meng pushed her bicycle into the courtyard gate.

"Sister, come over for dinner!" Li Liang hurriedly greeted, he thought that his sister would not go home at noon.

Chenchen, Junjie and Wang Chao also shouted their sisters, and although Zeng Xi came for the first time, he also called his sister generously.

Li Meng pushed the bicycle into the courtyard gate, and saw her brother and friends eating, she was a little surprised, usually her younger brother never cooks, today I don't know if it's Chenchen's cooking!

Li Liang picked up a pair of clean dishes and chopsticks from the kitchen, and poured Li Meng a glass of champagne: "Sister, I just soaked it in well water, drink it to quench my thirst!"

Li Meng took a sip of champagne and said with a smile: "Today's dishes are really rich, Chenchen, these dishes must have been made by you!"

"Sister Mengmeng, these dishes are all made by Liangzi!" Chen Chen explained.

"Liangzi made it?" Li Meng asked, "Liangzi, you haven't cooked before!"

"Sister, isn't that your credit?" Li Liang said with a smile, "You cook at home and I cook the fire, sister, your cooking skills are so good, I have learned a lot every day!"

After eating, Li Meng went to brush the bowl, Li Liang beckoned everyone to eat melons again, and the teenagers said that they were already very full, and in the end the watermelon was not cut. After playing with friends in the living room for a while, Wang Chao and Zeng Xi said goodbye and went back.

Chenchen also led Junjie back to take a nap, Li Liang helped his sister move her electric fan to her room and place it, Li Meng's room was simple and clean, and there were a few colorful stripes made by herself on the wall, full of girlish atmosphere.

After Li Meng finished washing the dishes, he also entered the room, turned on the fan, and enjoyed the cool breeze: "Liangzi, it's good to have a fan, and the summer will not be so difficult! It would be nice if we installed a few fans in the hospital." It was so hot that we had to wear nurse uniforms over our clothes to work, and at the end of the day, our bodies would stink. ”

At this time, the hospital did not have a central air-conditioning system like later generations, and the current county hospital even has few fans, and the nurses have to walk around to work, and it is simply miserable when it is hot in summer.

When Li Liang bought an electric fan in the morning, he had seen the casual work style of those salespeople in the department store, and there were actually salespeople who ate melon seeds at work, which was unimaginable after the 90s. It is only in the seller's market that there is such a shortage of materials as it is now.

"Sister, the working environment of the hospital is so poor, if you don't wait for the restaurant to get on the right track, you can simply resign and come back and open a restaurant in the county!" Li Liang said, he wanted to change the tragic fate of his sister in his previous life little by little.

"Liangzi, are your heads burned?" Li Meng said in surprise, "Although the hospital is tired of work, many girls can't get in our hospital now if they line up to get in." Besides, isn't our iron job bowl much better than that of self-employed people? If the policy changes one day, we won't let you do it. ”

This is also a common idea in society nowadays, and self-employed people are generally the things that young people who have returned to the city and unemployed young people do. As everyone knows, at this time, the self-employed are making a fortune, and most of the people who got rich first in later generations started from the self-employed.

If you want to change a person's mind, you have to take your time, not a day or two, and wait for the restaurant to make a profit. Li Liang thought about it, he didn't say anything more, said goodbye to his sister, and returned to his cabin.

Pressing the switch, the cool breeze drove away the afternoon heat. Li Liang took out his notebook and tried to recall the teaching materials he used when he was a teacher in his previous life. In the 80s, it was the time when China's education was restarting, and there were basically no teaching materials on the market, Li Liang was ready to summarize some good learning experiences and methods in advance according to the experience of later generations, so that he could not only complete the tasks assigned by the head teacher Wang Na, but also help children like him who were born in small counties.

What was the best thing about the 80s? It was an opportunity! The 80s provided very good development opportunities for the post-50s and post-60s, and many rural children who were admitted to university were equivalent to jumping into the dragon gate, and even if they were not admitted to university, there were many who went out to work and became self-employed; but after the 21 st century, the class gradually solidified, and it became much more difficult to change their fate by studying in college.

Li Liang remembers that in later life, he read several articles on the Internet, such as "A Brief History of an Atypical 985 Graduate" and "I Took 985 and 211 Only to Find Out That I Have Nothing", and he also agreed with some of the ideas in them. He is sometimes glad that he was born in the 60s, although he suffered a lot when he was a child, but through his own hard work, he finally survived; although he is not very rich and rich, he is also a little rich in the county.

Li Liang used to teach, and he knows what is the most important thing for primary and middle school students? It is memory! Many children do well in primary and secondary school because of how hard they study, but more because they are born with a good memory, remember a lot of things, and remember things quickly. Even in high school, the role of memory should not be underestimated, and students with excellent grades still consolidate their knowledge by constantly doing questions and strengthening their memory.

Therefore, enhancing memory can have a multiplier effect on learning. Therefore, in his previous life, Li Liang had done a lot of hard work to learn the Ebbinghaus memory method. Hermann Ebbinghaus (1850-1909) was a famous German psychologist who published his experimental report in 1885: people are exposed to information after they have been studied. Ebbinghaus once did a very famous experiment - he chose some meaningless syllables, random letter combinations, such as asww, cfhhj, ijikmb, rfyjbc, etc. He tested himself and got some data. Then, Ebbinghaus drew a curve based on these points, which is the famous curve that reveals the law of forgetting.

This curve tells people that forgetting in learning is regular, and the process of forgetting is fast, first fast and then slow. If you look at the curve, you will find that after a day, if you don't review it quickly, you will only be able to leave 25% of the original knowledge. Over time, the rate of forgetting slows down, and so does the amount of forgetting.

Someone did an experiment in which two groups of students studied a text, and group A did not review it after studying, and the memory rate was 36% after one day, and only 13% after a week. Group B reviewed according to the Ebbinghaus memory rule, and the memory rate was 98% after one day and 86% after one week, and the memory rate of group B was significantly higher than that of group A.
