Xueba's Sea of ​​Stars

Chapter 7 Pity the world's parents heart
At nearly 5 o'clock, Wu Bin returned home. As soon as he opened the door, he smelled a tangy fragrance.

"Mom, let's make hooves."

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

"You're back, come on, come here and have a taste." Wu Bin's mother, who was washing vegetables in the kitchen, shouted.

"Hey, come on!"

Wu Bin walked into the kitchen, picked up a spoon, scooped up a bowl of hoof soup, took a few breaths, and took a sip.

"Is it salty?" Wu Bin's mother asked, looking sideways at Wu Bin.

"Not salty, just right, very fresh."

Wu Bin was just about to take a second sip when he heard his mother suddenly ask in a cadence, "Isn't it salty?"

'Oops, something is wrong. '

Wu Bin, who smelled the strange smell in his mother's words, leaned out of the kitchen and glanced at his father who was sitting on the sofa watching "Happy Playing Big Cards", and found that he was also a little bit unhappy.

Wu Bin, who understood what was going on, took another sip of the soup and said, "I didn't feel like I drank less just now, but the second sip did feel salty, um, it's too salty!"

"Hey~ I'll just say it!" Wu Bin's mother raised her voice immediately, "Your dad, you have to add two spoonfuls of salt after tasting, he is getting more and more powerful now, and the smelly habit in the work unit brings Home is here!"

"What stinky habit did I bring back! Why do you get online at every turn?" Wu Bin's father immediately expressed his dissatisfaction when he heard that.

"Why, did I say you wrong?"

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

"No, Mom, I'll go and tell Dad to calm down."

After saying that, Wu Bin ran to the living room and said loudly and deliberately: "Dad, this is your fault. Go and apologize quickly."

"I did nothing wrong, I said..."

Wu Bin's father was halfway through speaking when he suddenly saw Wu Bin secretly raised his index finger and made a 1 gesture.

"This..." Wu Bin's father thought for a while after reading it, and then raised two fingers.

Wu Bin thought for a while and nodded.

Wu Bin's father is fond of drinking, but his capacity for alcohol is not very good. One time when he went out to attend a neighbor's son's wedding, he sneaked a few glasses of white wine. Wu Bin's mother strictly prohibited him from drinking alcohol.

But there is one exception that can be made, that is, Wu Bin drinks two drinks with his father, two votes to one vote, and thinking that it can enhance the relationship between father and father, Wu Bin's mother can at most say "don't drink too much."

Wu Bin's hand gesture to his dad just now means that if he is willing to give in to this wave, he will have a drink with him.

After the two cups were finally sold, Wu Bin's father ran to the kitchen, coughed lightly and said, "My wife, I was wrong. You are good at making soup. I shouldn't interfere, I shouldn't interfere."

"Stop doing this, put the dishes on the table, and get ready to eat."

Wu Bin's mother also knew that she was wronged, and now that she has face and face, she naturally didn't say much.

After resolving a "family crisis", Wu Bin sat down to drink soup silently, and continued to read his English books.

But he didn't read it for a while, Wu Bin's mother ran over and knocked down his book and said, "What's the point of pretending when you're eating?"

"Who's pretending to be a real reader?" Wu Bin said and picked up the English book.

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

Wu Bin's mother naturally didn't believe Wu Bin's words. How could she not know why her son was so aggressive in studying?

"It doesn't mean that, I just suddenly feel that learning is very interesting."

Wu Bin's mother was immediately amused, and said, "Okay, okay, mom is waiting for you to be admitted to Tsinghua University." ""

Wu Bin didn't expect her mother to believe him immediately, so she just continued to bury her head in the book.

"It's exciting, isn't it?"

Wu Bin's mother said that she was going to take Wu Bin's book, but Wu Bin's father stopped him by bringing over the meal.

"It's always a good thing for children to read books, so don't dampen their enthusiasm."

"It's not that you don't know your son. I chased him with a broom before and he didn't even read it. Now you can still like him?"

But although Wu Bin's mother still didn't believe it, she took back the hand that was grabbing the English book.

'Reading is really a privilege. '

Looking at his own mother who stopped talking, Wu Bin couldn't help but sigh in his heart. He used to be talked about for a long time even if he took out his mobile phone to read a few messages during meals.

After dinner, Wu Bin drank two glasses of yellow wine with his father, went back to the room and took out the sets of papers Liu Yushan gave him from his school bag, read the questions for a while and started to work.

During this week, Wu Bin has been dealing with functions almost all the time. At the beginning, he was able to do a few finger functions and comprehensive application questions on functions very smoothly, but then the abstract function that gave him the most headache was a bit annoying.

Moreover, Liu Yushan and him have emphasized that abstract functions can comprehensively examine students' understanding of the concept and properties of functions, and also integrate the domain of definition, value range, monotonicity, parity, periodicity and images of functions, so The frequency of appearance in the college entrance examination is very high, and it is the top priority in learning.

Originally, Wu Bin's knowledge of functions was not that comprehensive. To prove this kind of question is simply a headache, but it can't be empty, so I have to do it.

In the end, Wu Bin solved the problem with difficulty by using the method of changing yuan. Of course, the feeling of victory is wonderful. Wu Bin drank Wangzai's milk happily to express his celebration.

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

In 2008, a city built 100 million square meters of new housing, including 25 square meters of affordable housing. The relevant departments plan to increase the area of ​​newly built housing by 5% every year compared with the previous year, of which the economical housing will increase by 10 square meters each year.According to this plan, which year was the first time that the area of ​​affordable housing built in that year exceeded half of the area of ​​new housing in that year?
Wu Bin stroked his chin and thought for a while, then began to calculate on the draft paper.

设第x年新建住房面积为f(x)＝100(1＋5%)x，经济适用房面积为g(x)＝25＋10x，由2g(x)>f(x)得2(25＋10x)>100(1＋5%)x
Finally substitute the known conditions into the verification...

"That's 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 feeling a little swollen, humming a little song and continuing to do it.

……

At 2 o'clock in the morning, Wu Bin's mother got up at night to go to the toilet. When she came out, she found that the light in Wu Bin's room was still on. She couldn't help shaking her head, "She also said that she should study hard, so why not play games all night."

After finishing speaking, he walked over and pushed open the door of Wu Bin's room, "What time is it, and you're still awake! I see you...huh?"

Just as Wu Bin's mother was about to scold her, she realized that Wu Bin seemed to be...doing a paper?Judging from the densely written draft paper on the table, it doesn't seem like he's pretending, or he doesn't need to pretend to show it to himself. After all, for this son, she has already stated that she only asks him to be kind-hearted. As long as you are in good health, if you are struggling with talent like reading, you can’t do it.

"Oh, I'm going to sleep right away." Wu Bin turned his head and said with a fairy face.

"Oh, you child, you don't work so hard." Looking at Wu Bin with a tired face, Wu Bin's mother revealed distress in her tone.

"Bad foundation, there is no other way, we can only fight." Wu Bin smiled at his mother.

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

"It's really a bit. Do you have wontons?"

"Yes, I'll pack it for you now, just wait."

After 20 minutes, Wu Bin, who was eating hot wontons stuffed with pork and cabbage, said while eating, "Mom, go to sleep. I'll finish this paper."

"Mom is not sleepy, I just want to stay with you for a while." Wu Bin's mother patted Wu Bin's head, "Doesn't affect you?"

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

Wu Bin brought a small chair to his mother.

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

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

Looking at the expression on his mother's face, Wu Bin couldn't help but sigh a little. Although she always said verbally that it's okay if she doesn't like to study, and a good heart can gain a foothold in society, she is actually very worried in her heart. After all, in this real society , Without a good diploma, it is really difficult to survive.
