Scholar’s Starry Sea

When it was almost 5 o'clock, Wu Bin returned to his home, and as soon as he opened the door, he smelled a tangy fragrance.

"Mom, do hoofs."

Wu Bin put down his schoolbag and went straight to the kitchen.

"Come back, hurry, come and taste it." Wu Bin's Mother who was washing the vegetables in the kitchen shouted.

"Hey, come!"

Wu Bin walked into the kitchen and picked up the soup ladle to scoop out a bowl of hoof soup. He took a breath and took a sip.

"Is it salty?" Wu Bin's Mother asked when she turned her head to look at Wu Bin.

"It's not salty, just right, it's very fresh."

After Wu Bin was about to take a second sip, he heard my mother suddenly ask some questions. , "Not salty, isn't it?"

'Aiya, the situation is not right. '

Wu Bin, who smelled the strange smell of his mother's words, peeked out of the kitchen and glanced at the old man who was sitting on the sofa watching "Happiness", and found that his face was also a little uncomfortable.

Wu Bin, who understood what was going on, took another sip of the soup and said, “I didn’t think I drank too much. The second bite did feel salty, um, too salty!”

"Hey~ I'll just say it!" Wu Bin's Mother's voice immediately rose up, "Your dad, you have to put two more spoons of salt after you taste it. He is getting stronger and stronger now. The stinky habits are brought home!"

"What stinky habits have I brought back! Why do you go online at every turn?" Wu Bin's Father immediately expressed dissatisfaction.

"Why, did I say you wrong?"

Seeing Mother was about to pick up the spatula and run out of the living room, Wu Bin quickly stopped her.

"Don't, mom, I'll go and tell father, you calm down."

After Wu Bin, he ran to the living room and deliberately said loudly, "Dad, this is yours. It’s not right. Hurry up and apologize."

"I didn’t do anything wrong again, I said..."

Wu Bin's Father was halfway through, and suddenly I saw Wu Bin secretly stand up Index finger, compared to a 1 gesture.

"This..." Wu Bin's Father thought about it after reading it, and then raised two fingers.

Wu Bin thought a little, nodded.

Wu Bin's Father is good for drinking, but the amount of alcohol is not very good. One time when I went out to attend a neighbor’s son’s wedding, I secretly greeted a few glasses of white wine. He woke up after a while, and Wu Bin's Mother strictly prohibited him from drinking.

But there is one case where an exception can be made, that is, Wu Bin accompanies his dad to drink two glasses, two votes to one vote, and thinking that it can enhance the relationship between the two of them, Wu Bin's Mother can say at most " Don’t drink too much."

Just now, Wu Bin gestured to his dad, which means that if he is willing to accept this wave, he will accompany him for a drink.

Finally after the two cups were sold, Wu Bin's Father rushed to the kitchen and lightly coughed and said, "My wife, I am wrong. You are good at making this soup. I shouldn't interfere, shouldn't interfere."

p>

"Come to this set less, bring the dishes to the table, and get ready to eat."

Wu Bin's Mother also knows that she is a little bit wrong, and now she has all the face, so naturally she won't say much .

Wu Bin, who had resolved a "family crisis", sat down to drink soup in silence, and continued to read his English book.

But after he didn’t look at it for a while, Wu Bin's Mother ran over and knocked out his book and said, "What is the pretense when eating."

"Who pretends? Yes, really read a book." Wu Bin said and picked up the English book.

"Hey, the acting is quite similar, want to add pocket money?"

Wu Bin's Mother naturally doesn't believe in Wu Bin's words. Why does her son study? Don't you know?

"It didn’t mean it, but I suddenly found it interesting to study."

Wu Bin's Mother was amused at once and said, ""Well, good, mom waits for you to pass Tsinghua University what. ""

Wu Bin didn't expect her mother to believe him all at once, and simply continued to read.

"Well, isn't it?"

Wu Bin's Mother said she was going to grab Wu Bin's book, but was stopped by Wu Bin's Father who came over with a meal.

"Child reading is always a good thing, so don't discourage his enthusiasm."

"You don’t know your son. I used to chase after him with a broom to read him. If you don't read it, you can still like it now?"

Although Wu Bin's Mother still doesn't believe it, but the hand that grabbed the English book was taken back.

'Reading is really a privilege. '

Looking at his own mother who is no longer talking, Wu Bin couldn't help feeling emotionally. He used to be told for a long time even if he took out his mobile phone to read a few messages when eating.

After dinner, Wu Bin drank two cups of yellow with his father. He took out the sets of papers Liu Yushan gave him from his schoolbag at return to house, and began to read the questions for a while. Do it.

In this week, Wu Bin has been dealing with functions almost all of the time. At first, the functions and comprehensive word problems of functions are very smooth, but the abstract functions that give him the most headache next. It's a bit annoying.

Furthermore, Liu Yushan and he emphasized that because abstract functions can comprehensively examine students’ understanding of the concept and properties of functions, they also combine the domain, range, monotonicity, parity, periodicity, and The image set is in one body, so it appears very frequently in the college entrance examination and is the top priority in learning.

Originally, Wu Bin's function knowledge is not so comprehensive. To prove that this kind of question is simply scalp numb, but it can't be left empty, so it has to be chanted.

Finally, Wu Bin used the exchange method to solve this problem difficultly. Of course, the feeling of victory was wonderful. Wu Bin elated drank Wangzi's milk to express his celebration.

After celebrating, Wu Bin stretched his waist and continued to challenge the next question.

In 2008, a city built 1 million square meters of new housing, among which 250,000 square meters of affordable housing were built. The relevant departments plan to increase the area of ​​newly built housing by 5% over the previous year in the future, of which the economically affordable housing will increase annually. 100,000 square meters. According to this plan, when was the area of ​​affordable housing built that year exceeded half of the area of ​​newly built housing that year for the first time?

Wu Bin touched his chin, thought about it, and started to calculate on the draft paper.

Suppose the area of ​​newly built housing in the xth year is f(x)=100(1＋5%)x, and the area of ​​economically affordable housing is g(x)=25+10x, and 2g(x)f(x) is 2 (25＋10x)100(1＋5%)x

Finally, substitute the known conditions into the verification...

"That is, X=4." Wu Bin tapped the test paper with his pen.

So the answer is 2012.

Wu Bin, who easily solved a problem, couldn't help but swell, humming a small song and continued to do it.

……

At 2 in the morning, Wu Bin's Mother got up at night and went to the toilet. When she came out, she found that the light in Wu Bin’s room was still on. She couldn’t help but shook her head. Study hard, don’t play games all night."

After that, I walked over and pushed open the door of Wu Bin’s room, "What time is it, I’m still awake! I see you...eh?"

Wu Bin's Mother just wanted to scold him, only to find that Wu Bin actually seemed to be...making papers? Judging from the densely packed draft paper on the table, it didn’t look like it was pretending, or he didn’t need to pretend to show it to himself. After all, for this son, she had long stated that she only asked him kind- Hearted, good health is good. Reading is a matter of innate talent. If it doesn’t work, it won’t work.

"Oh, I will fall asleep soon." Wu Bin turned his head and said with a face of Immortal Qi.

"Oh, you child, you don't work hard like that." Looking at Wu Bin with exhaustion, Wu Bin's Mother's tone revealed distress.

"The foundation is poor, there is no way, I can only fight." Wu Bin moved towards his mother laughed.

"Then are you hungry? I'll cook something for you."

"Really a little bit, do you have wontons?"

" Yes, I’ll wrap it for you now and wait."

20 minutes later, Wu Bin who ate hot cabbage and pork wontons while eating said: "Mom, go to sleep, I Just finish this paper."

"Mom is not sleepy, I want to be with you for a while." Wu Bin's Mother touched Wu Bin's head, "Isn't it affecting you?"

p>

"It doesn't matter, just sit here if you want to accompany you."

Wu Bin carried a small chair in front of Mother.

"It's okay, I'll just stand and watch for a while."

"Okay, then I will continue to do the questions."

Looking at Mother’s face With her expression, Wu Bin can’t help but sigh. Although she always says that she doesn’t like to study and it’s okay, she can gain a foothold in society with a good heart, but she is still very worried in her heart. It's really hard to survive.
