Go back to the year of the high school entrance examination

The last question is a flow chart for the production of raw materials for industrial production. Each step is accompanied by a chemical reaction. The arrow is used as an indicator. There are problems of calculating the mass of a certain substance and filling in the chemical formula of a certain solid substance. The topic is relatively comprehensive.

When Ji Shi just came back, it is not an exaggeration to say that among the chemical substances he is most familiar with is H2O, and he has basically forgotten everything else. The basics have to be replenished from junior high school, but junior high school chemistry is not the same as high school chemistry. The difference is too much.

Ji Shi started from the first blank of this question. The first blank is the simplest of several small questions. It is enough to make a response based on the original data and then calculate the quality.

Every time he writes a chemical reaction, it is a long list, and the draft paper is full. He must not be distracted, and he must be careful, because if he writes one more letter or one less letter, the chemical formula of the substance will be completely changed.

"the answer is……"

Ji Shi confirmed that it was three, and wrote the answer he had calculated on the horizontal line.

The second space is to write a chemical formula. This kind of topic often makes mistakes. Sometimes he ignores a certain detail, and the whole problem is completely wrong. Therefore, when he usually practices, he tries to be more careful and try to write the formula as clearly as possible. Very detailed, sometimes when he discussed chemistry problems with Zhou Weile, the other party would sometimes dictate formulas without using a pen to write them down, or write them very briefly, and Ji Shi was overwhelmed with admiration.

It is a pity that he does not have such a level himself.

Write the formula honestly, don’t omit it if you can, and write as long as you can, so that even if you make a mistake, you can see your thoughts at a glance when you look back.

Ji Shi groaned and groaned as he wrote the formula, first a certain substance was produced after a high-temperature reaction, and then...

This kind of question really gave him a headache.

It's a pity that no matter how painful it is, I can't escape it. I still have to write what should be written.

This question took nearly 10 minutes. According to his usual practice experience, today is considered fast. There is still a lot of time left before 2 hours. His speed was really slow when he first started practicing. Forget it, there are often a lot of blanks on the test paper that I can't write.

Fortunately, the old donkey didn't scold him because of this, which allowed Ji Shi to reach a level of mental health that could fill up the test papers.

In the third space, Ji Shi had some difficulties again. He was a little confused when he first read this question, and he didn't have any ideas in his mind. It took a long time before he almost understood the point of the test.

Only by understanding the question can you know how to do it. Ji Shi followed the train of thought of the question, and finally figured out a reaction process, and then substituted the knowledge points he had mastered. It took a long time, and finally filled the gap up.

There are four small spaces in this question. When he wrote the fourth space, the exam time he set was also exceeded. The main reason is that he spent too long on the first few spaces. I'm afraid it's empty there.

Ji Shi finally filled in the fourth blank. It took a long time, and the correct rate is actually unknown. He will check the answers with Zhou Weile and Yao Meng later to see if their answers are the same as his.

After finishing this set of test papers, it was almost noon. Ji Shi couldn't stay in bed too much, so he just got up, washed his face and brushed his teeth, and went outside for a couple of strolls before coming back to read the second set of math test papers.

His feeling is that the old donkey has worked hard on these two sets of test papers. It has to be said that the knowledge points examined by the two sets of test papers are very comprehensive, and the difficulty is also very high. All in all, it is impossible to finish the test papers by being clever. Yes, each set of test papers has to be devoted to doing it.

Not long after the start of the second set of test papers, Ji's father and Ji's mother came home from outside. When they saw Ji Shi's appearance, they frowned: "You didn't eat breakfast today, did you?"

The down jacket is quite thick, and the pants on the legs are not warm at first glance. Looking at the messy hair, it looks like he got up from the bed not long ago.

Mama Ji went to the kitchen to see that the steamed buns on the pot were cold.

She had no choice but to heat it up again, and gave Ji Shi another bowl of porridge: "It's okay to put homework first, remember to eat, if you don't eat, you will become a fairy?"

The porridge is served with small pickles, freshly fried pickled vegetables, and fried with tofu. The pickled vegetables are locally grown potherb mustard. However, I still eat a lot of pickles at home, such as potherb mustard and dried radishes. Although the pickles sold outside may not be as rich in taste, at least those who eat at home know what is added in them.

Some delicacies in the countryside are also gradually being lost. Compared with Grandma Ji Shi's generation, Mother Ji and the others still cook very little. The main reason is that the work in the fields is busy, and the vegetables and food grown are becoming more and more difficult to serve. I can't afford to do anything else.

When Ji Shi was a child, the main crops at home were wheat, corn, rape and cotton, but the economic benefits of these were low, so gradually, the family began to grow watermelons, vegetables, and corn and rapeseed, but the area was no longer comparable to before. up.

Ji Shi remembered that when his grandma and old lady were still alive, the corn was peeled by hand without using a thresher, and the rapeseed was harvested by others. The net is spread on the ground, and the rapeseed falls on it.

Ji Shi’s family can’t even find the lid now. They used to beat rapeseed and soybeans with the lid. The lid is made of bamboo. There is a handle on the side of the pole to connect the bamboo raft to the pole. With such a force, the rapeseed can be knocked down.

Grandma Ji Shi passed away early, but when she was still there, she would eat omelets at Ji Shi’s stall. Ji Shi almost forgot what it tasted like now, but he remembered that it was very delicious, much more fragrant than the finger cakes sold outside. It's not oily, so if he wants to eat now, he can only go to the neighbor's grandma's house, because Ji's mother can't cook.

There is also a kind of fried flour that his grandma can also make. Fry the flour until it is burnt yellow and seal it up. When you want to eat it, soak it in boiling water and add some sugar. The taste is also very good, but Ji Shi has not eaten it for almost 20 years. Yes, now that I think about it, I still miss it.

Buns are big meat buns bought in the town. The family is busy with work. Ji's mother has no time to steam buns and steamed cakes until the off-season. This year, if there is no accident, she will not be able to steam anything, because she has to stay with Ji Shi in the county. .

But generally speaking, if Ji's mother didn't make it, their family should be able to eat four kinds of buns, because aunts and grandma can steam them, and they will definitely share them with their families.

……

Ji Shi didn't feel it when he was doing the questions. After taking the first bite of the buns, he realized that he was really hungry. He started to gobble up the buns immediately. Ji's mother steamed the buns in a pot. There were meat buns, and there were also shredded radish buns. After eating three in a row, I drank a big bowl of porridge.

Mama Ji: "...do you still have lunch like this?"

"eat!"

Today's lunch is at the aunt's house. Although the aunt's house is not as close as the second aunt's house to Ji Shi's house, it is only 1 kilometer away. It takes more than ten minutes to walk there, and it is faster to ride a bicycle. Ji Shi saw it In his spare time, he will do some more homework, and when he comes back from lunch, he will definitely finish the chemistry test paper.

As long as the old donkey doesn't ask those difficult questions.

But at this point, Ji Shi never had any illusions. Their entire grade knew that the test papers of the chemistry group were definitely not something that could be easily passed.

Starting to write the test paper again, Ji Shi couldn't help feeling a little regretful, he shouldn't have eaten three steamed buns in one go, and now he feels his stomach is a bit full, the oil content in his brain may be too high, and his brain cells are not active enough.

Ji Shi went out to shake again.

The weather has been fine for the past few days of the holiday. The sun has come out now, and it is warm on the body. Ji Shi walked around the path of the neighbor's house, went around their house, and walked west again. Bypassing a lake, he detoured from the road next to the second aunt's house.

The cousin was pumping water by the well, when Ji Shi happened to come over, she waved him to lift the bucket into the kitchen.

"Are you going to your aunt's house today?" she asked.

"Go." Ji Shi nodded.

"Come with me later, my battery car has been sent to the town for repair."

"it is good."

Ji Shi guessed that he would not be able to write the chemistry test papers for the time being, but he estimated that with his current state, it would be difficult to write a set of test papers very well.

Anyway, he closed the door of the house, so he just played at the second aunt's house for a while.

My cousin downloaded Lianliankan from her notebook and let Ji Shi play it. Ji Shi is not very interested in this kind of game that doesn't show much intelligence, but it's probably because he hasn't played it for too long. He clicked with the mouse and played it for several times close.

There is also Zuma in the notebook, which is a game that eliminates the beads to prevent the beads from rolling into a hole and ends. Ji Shi couldn't help playing again.

...He is not obsessed with games, he is just consuming the buns he just ate.

When it was lunch time, Ji Shi first gave the key to his mother, and then he and his cousin went to the aunt's house.Auntie's house and Ji Shi's house don't belong to the same village group, and they have to pass a river dam when they leave. Ji Shi used to come here to fish lobsters when he was a child, and the village committee and kindergarten of his village are also here, but they have withdrawn ten years ago. It has been several years, and Ji Shi still remembers that the stationery that was stolen on his first day in kindergarten was bought for him by his uncle, and it disappeared when he carried it on his back. He was very sad at that time.

There are very few people walking on this road, and the road is very narrow, and cars cannot pass through it. Even tricycles driving on it must be careful to fall into the river ditch.

But he and his cousin are very used to this road, because when they were young, their eldest uncle was a regular worker in the factory in the town, and the factory had not been restructured at that time, and the life of the eldest uncle’s family was much better than that of the two of them. They went to have meat to eat , and drinks, and my eldest uncle has a good temper, unlike Ji Shi who is occasionally beaten, my cousin is often beaten.

"I heard from my mother that your grades are pretty good now?"

"It's much better than before. The last time I was in grade 11 in Chinese, but not in physics and chemistry. It's very dangerous."

"Grade 11?" The cousin's eyes widened. "I couldn't even pass the class 11 in high school."

Ji Shi: "I am the closest."

And the cousin is definitely not the kind who can't study, she just likes to eat, drink, and buy two nice clothes, and she doesn't care about studying at all. Later, she was in the third year of high school, and was suppressed by the second aunt for a year, and she was admitted to the undergraduate course.

Many people in their village don't go to school after graduating from junior high school, and it's not because their parents don't give them permission, but mainly because they can't go to school.

"That's amazing, too, very good."

Cousin doesn’t focus on studying, so she doesn’t care about other people’s grades, she doesn’t know how to compare. Ji Shi has been with her for more than 30 years. The only time she felt disappointed was when she participated in the high school reunion. , It should be relatively late, some students in their class became college lecturers, and some students became mayors in their hometown town, life seemed much more satisfactory than her.

But that was the only time, and she complained to her sisters and brothers at home during the class reunion, and she didn't care after two days.

"Anyway, I can't do it for me. It's pretty good now. People have to learn to be content."

The two walked slowly on the road, the cousin's mobile phone was turned on, and the two listened to Jay Chou's songs together, but after playing three or four songs, they crossed the dangerous bridge at the entrance of Dagu's village.

When they were young, people always said that there was a water ghost under this bridge, and someone's old lady was buried under it, so at that time, although Ji Shi knew every river in Shili Baxiang, this one really didn't dare to wander under it. .

In terms of geographical location, the aunt's house is more remote than theirs, and there are many people who buy houses outside, and there are not many houses in the front and back.

Ten years ago, the area belonging to her family had the largest number of people, and since then there have been fewer and fewer people, and all the neighbors have gone to live in big cities.
