By the end of the semester, everyone seemed busy.

Revision, exams, drinking and eating meat, and studying for exams while drinking and eating meat.

There is only one winter solstice in a year, and the winter solstice is indispensable.

A few bottles of liquor, a few friends, good wine, good meat, good youth, live up to the pride of youth.

The cup does not stop, the wine is full, and there are three more glasses of this glass and three glasses.

"Today...... Today's meal for me ...... I please. Xia Lu was really happy to drink, he had never drunk so much liquor in his life.

The liquor is refreshing to drink for a while, and it is refreshing to drink it all the time, and Xia Lu is very refreshing.

"Xia Sanbai is drunk. Du Shengyong said.

In the three exams that have ended this semester, English, Ma Zhe, and Mathematics, Xia Lu has scored three 100 points in a row, and so far, Xia Lu has one full score player in the class.

Coinciding with the winter solstice, the four people in the summer road dormitory drank wine and ate meat to enhance the friendship between classmates.

"If you say that AA is good, you will implement it according to the original plan, and don't break the rules. Zhang Kai did not agree to let Xia Lu have a treat, and said that AA would be AA, which was a matter of principle.

"I'll pay the bill, and you will give me a red envelope back. Qin Yibo stood up and prepared to pay.

"Qin ...... Qin Yibo...... You sit down for me...... I'm going to buy ......" Xia Lu said and said that there was no further text, his limit had been reached, and he was drunk.

Everyone drank a bottle of liquor, and only Xia Lu was drunk, although his alcohol consumption was much better than before, but it was still a little worse than the three roommates.

Just after the winter solstice, it is Christmas Eve in the blink of an eye.

There is only one Christmas Eve in a year, and Christmas Eve is indispensable.

Several postures, a few back and forth, good men and women are so happy, and they live up to the clouds and rain in Wushan.

Don't stop, I'm okay, I've done it three times this time.

The little couple next door to Xia Lu's house is as loving as ever, Christmas Eve BUFF blessed the divine power, and the little couple was three times after three times, and the energy of love was unstoppable.

Everyone craves wealth, and so does Xia Lu.

If he has money, Xia Lu wants to buy a villa for his parents to live in.

After all, I have lived in this house for many years now, and the sound insulation effect is really not good.

Holy Christmas Eve is a weekend, and Xia Lu spends it at home with his parents.

At this time last year, Xia Lu's family of three reunited to eat hot pot.

At the moment, they are still eating hot pot at home.

Xia Lu ate, drank and chatted: "The relationship between the couple next door is really good. ”

Xia Guohua took a sip of wine and said: "The tip is the husband of the couple next door, he usually buys twenty yuan of cigarettes in our store, and the standard of tip has been lowered to ten yuan recently." ”

Xia Lu: "It seems that the young couple is short of money." ”

Xia Guohua: "Their income has not decreased, but they want to have children. With children, the old man will come and take the child, then the house is not big enough. If you sell your current house, you still need to add some money to get a bigger house, so the tip can only be ten yuan for cigarettes. ”

Xia Lu was a little incomprehensible: "If you want to have a child, then don't smoke, smoking has an impact on conceiving a baby." ”

Xia Guohua shook his head and said, "We have quit smoking, what business do we still have?"

Xia Lu asked, "Dad, did the tip tell you that they want children?"

Xia Guohua: "I made observations based on life experience. ”

Cui Min glanced at Xia Guohua: "Old Xia, don't talk nonsense, the tip couple doesn't want children at all, they are the Dink family." Do you know what a dink is? It's a couple who don't have children. ”

Xia Guohua asked rhetorically: "If you don't have children and don't have a burden, why do you save money to buy cheap cigarettes?"

That's because the tip wants to save private money, and when his wife celebrates her birthday, he gives his wife a scooter. Cui Minhong said what she had, and she was full of praise for Tip, who was simply a model husband in her mind.

Xia Guohua retorted: "This reason is very fake, tips save ten yuan a day, 300 yuan a month, and only a few thousand yuan a year." How can it cost tens of thousands of yuan to buy a small-displacement car for transportation? Many years later, tips can be used to buy a car for his wife. ”

Cui Minhong retorted: "Time is not a problem, the important thing is attitude." ”

"I'm surprised, the tip wants to surprise his wife, how do you know about such a secret thing?" Xia Guohua pointed out an obvious loophole in Cui Minhong's remarks.

"I naturally have my information channels. Cui Minhong said mysteriously.

"Dad, Mom, you are too strong...... "Xia Lu can't accept it, his parents are the real bosses in this community.

The love and hatred of neighbors, the joys, sorrows and sorrows upstairs and downstairs, the firewood, rice, oil and salt in their own homes, and the trivial things constitute the daily life.

The vast majority of the world's people spend most of their time coping with these trivial things, and that's life.

Back at home, Xia Lu was happy to talk to his parents about these trivial parents.

And what parents are most concerned about is Xia Lu.

"Xia Lu, is the food in your school good?"

"Abundance and thrift are made up of people, if you have money, you can eat well, and if you don't have money, you can eat enough. ”

"Is there enough money?"

"Of course, the scholarship I was given when I entered the school was enough for me to use until I graduated. ”

"Don't be too provincial, you still have to invite female classmates to go out to play. ”

"Please, please, please. ”

Xia Lu took out his mobile phone and wondered which female classmate to invite out to play and spend Christmas together.

After thinking about it, don't invite it, you have to save money from now on, save money to buy a villa.

After Christmas, it's New Year's Day in the blink of an eye.

Before New Year's Day, the students in Xia Lu's class had to take a test, chemistry.

Chemistry professors pay more attention to experiments, and students' usual chemistry experiment performance accounts for half of the score, and a large number of chemistry experiment questions also appear in this chemistry final exam paper.

What should I do when I weigh a sample and the two-arm analytical balance cursor scale moves toward the sample end, or when the single-arm analytical balance cursor scale moves downward and cannot reach equilibrium?

Please describe the method of preparing and storing Fe2+ aqueous solution.

Weighing the solid KMnO4 in boiled and cooled distilled water × or √ √ without explanation. If ×so, correct it.

What kind of instrument is needed for titration with KMnO4 standard solution?

……

Chemistry lab questions such as these account for more than 50% of the marks in the test paper.

It's really not difficult at all, as long as you have done experiments, these are all points.

Xia Lu likes to do the most experiments, biological experiments, chemistry experiments, physics experiments, he has a good experimental performance.

After finishing and handing in the papers, Xia Lu breathed a sigh of relief. Mathematics and chemistry have been completed in the core courses of the major, and physics and biology are left.

Xia Lu had already received a perfect score in mathematics, and he felt that the final score in chemistry should be quite high.
