Conservation of energy

Luo Sensen clamored to buy a mobile phone, saying that most of the students in the class had mobile phones, and he had to buy one himself. Sensen’s mother had no choice but to take Sensen and Luo Xintong to the mobile phone market on weekends. Luo Sensen picked the latest Sony Ericsson Tong Jiazhi insisted on buying the W888 orange slider phone for Luo Xintong. Luo Xintong chose the Nokia N72, which was relatively cheap. After the two of them came back, they fiddled with the phone all afternoon. Luo Xintong went home and installed the phone number. Immediately, he made a call to his mother, and then saved the numbers of his family members. After that, Luo Xintong downloaded a few popular songs at the time, and of course Xingqing and Jay Chou's songs, and finally downloaded the mobile phone QQ , Shen Lin and Luo Sensen are actually two friends in QQ, and I think it's a little funny, after all, the three meet every day.On Monday morning, Luo Sensen went downstairs with earphones, and met Shen Lin who was waiting for the two of them. Shen Lin was also wearing earphones. Luo Sensen yelled and asked Shen Lin what song he was listening to. , Rosensen unplugged his earphones and smiled, Britney Spears' Toxic, with the taste of your lips, I'mon. Each person had a toffee, and said with a smile: eat it, it's not poisonous. Rosensen happily put the candy in his mouth, and the three of them rode bicycles to school all the way.

At noon, Luo Xintong and Shen Lin played basketball for a while. The two sat on a chair. Luo Xintong took out his mobile phone and asked Shen Lin for his phone number. Shen Lin reported a series of numbers. The mobile phone was about to write Shen Lin's name on it, but Shen Lin snatched the mobile phone, saved "Xingqing" in Luo Xintong's mobile phone, and then returned the mobile phone to Luo Xintong. Luo Xintong looked at the name of the mobile phone number, Seeing that Shen Lin saved "Xintong" in his mobile phone, it was also his screen name, Shen Lin smiled, and Luo Xintong saw Shen Lin smiling, and he also laughed along with Shen Lin.

With a mobile phone, it is much easier for the two to communicate. At that time, the students used China Mobile's M-Zone, and there were 300 free online text messages every month. Usually, the two would send text messages to each other when they were in school. When I'm free at home, I hang on to QQ on my mobile phone, and don't chat because there are only a few people on QQ. Shen Lin is often online on QQ on his mobile phone. From time to time, he will send some funny jokes to Luo Xintong. Replying with a smiley expression covering his mouth, the expression replied a lot, Shen Lin would ask him why he keeps posting expressions, Luo Xintong only said that he was too lazy to type.

The semester is coming to an end, and the students are busy preparing for the final exam. Even Luo Sensen has started to study seriously. Luo Xintong and Shen Lin no longer play basketball. They will have lunch together at noon, and then go to the library When reading books and doing test papers, Shen Lin still often brings some candy to eat, and noticed that Luo Xintong doesn't like eating too sweet things. Sometimes Shen Lin would bring some peeled nuts to Luo Xintong. They are not very interested in the snacks. Shen Lin only said that eating nuts nourishes the brain and will make you smarter and help you learn. Usually, Shen Lin stuffs a few nuts into Luo Xintong's mouth. Luo Xintong asked Shen Lin why He likes to eat sweets so much, Shen Lin said with a smile that eating sweets can maintain a happy mood, Luo Xintong advised him to eat less candy, as it would cause tooth decay, Shen Lin said that after all the teeth were decayed, he would replace them with porcelain teeth, so that they would be whiter and brighter The flashy kind, after speaking, Shen Lin laughed, Luo Xintong looked at Shen Lin's white teeth, and could only smile.

Luo Xintong's grades in the final exam were normal, and he was still in the top 11 of the grade. Luo Sensen's Chinese and English exams were also good, but the science exam was a mess, and he even failed in biology. There are no liberal arts and sciences, and the liberal arts are obviously lagging behind. History, political geography just passed, mathematics and physics even took the first place in the class, and physics even took the first place in the grade. Luo Zhengwen is very happy, knowing that Luo Xintong and The two children of Shen Lin had a good relationship, so Luo Xintong asked Shen Lin to come over for dinner. Anyway, they were in the same community, so it was convenient to come here.Luo Xintong agreed and told Shen Lin about it, and Shen Lin agreed after hearing it.On weekends, Tong Jiazhi cooked a table of dishes. When the three children were growing up, they all could eat. Tong Jiazhi was busy in the kitchen, and Luo Zhengwen was also busy in the kitchen. Luo Xintong read a book, Luo Sensen closed the door in the room and didn't know what he was doing. Luo Xintong arrived at Luo Xintong's house at about [-] o'clock. Luo Xintong opened the door, and Shen Lin saw Luo Zhengwen and Tong Jiazhi busy in the kitchen. He didn't recover for a long time Come on, I even forgot to give Luo Xintong the fruit in my hand, Luo Xintong pulled it a few times, and Shen Lin let go.

Luo Zhengwen and Tong Jiazhi greeted Shen Lin, Luo Xintong invited Shen Lin to enter their room, Shen Lin looked at Luo Xintong's room, only a few square meters of room was cleaned by Luo Xintong, only a 1.5 Mi's bed, a small wardrobe, a desk with a few books, a chair, and a large bookshelf, Luo Xintong went out to pour Shen Lin a glass of water, Shen Lin's attention was all on Luo Xin There are a lot of books on the shelf, and there is a family portrait. When Luo Xintong saw Shen Lin looking at the photo, she handed it to him. She wiped the dust that did not exist on the photo frame with her hands, and said, this is her own. Shen Lin saw in the photo a woman with gentle eyes and firm eyes holding a boy who was about seven or eight years old, and a young boy who was about as tall as the woman was standing next to him. Luo Xintong explained with some embarrassment that that was When I first entered junior high school, I took a photo in front of my yard, and it was taken by my godfather. In the photo are my mother and my younger brother.Shen Lin felt that the scene of this photo seemed familiar, so he searched his memory to make sure that he had never been to this place, and after thinking about it carefully, it turned out that it was the yard where he and Luo Xintong watched the stars together in a dream...

Luo Xintong asked Shen Lin to sit on the bed, and the two started chatting, talking about the choice of arts and sciences next semester, Shen Lin replied that he would choose science, and also said that he would ask Luo Xintong for advice, and he would inevitably harass him frequently.The two were chatting, and Tong Jiazhi had already cooked the meal, so they asked them to go out to eat.Luo Zhengwen poured a few glasses of wine, saying that it was to celebrate the results of the final exams of the children. Luo Zhengwen usually does not drink, and only poured a small glass of plum wine in front of the five people. Luo Zhengwen held up the glasses to congratulate them The child has achieved good results in the final exam this time, and I hope to make persistent efforts next year.The plum wine has a very low alcohol content, and it tastes sour and sweet and very refreshing. Both Luo Xintong and Shen Lin drank the small glass of wine as if it were a drink. After all, the children are still young, and Luo Zhengwen didn't give them any more. To pour wine, Tong Jiazhi gave each of the children a bottle of warmed soy milk.Luo Zhengwen asked Shen Lin about his plans for the New Year. Shen Lin thought for a while and replied that he would spend time with his grandparents. Luo Zhengwen realized that the topic was wrong, so he planned to change the topic. Immediately answered, Luo Xintong gave Luo Sensen a wink, but Shen Lin confessed that his parents divorced and each started a family, but Luo Sensen suggested that Shen Lin go back to the countryside with them during the Chinese New Year.Luo's father and Luo's mother persuaded the children to eat vegetables and grow up. Luo's mother even picked up a piece of bacon brought by Luo Xintong's mother for Shen Lin. Shen Lin picked up the bacon, as if thinking about something on his mind, but his hands were full for a long time. She didn't move, it was because Luo's mother said that Luo Xintong's mother brought the bacon from the countryside, and then she came to her senses, eating the bacon felt delicious, and Shen Lin picked up a few more pieces.
