Before returning to the college entrance examination, I became popular in the science circle

"Okay, okay, I'm so big, and I'm still crying like a cat, so I'm ashamed!"

After all, it was her own mother, no matter how hard Jin Yu talked, her heart towards her daughter was still soft, she gently patted her back to comfort her, pulled her to sit on the sofa in the living room, took the wet towel handed over by her lover attentively, Wipe your daughter's face, and then pass over half of the uncut watermelon with the spoon inserted.

"Here, eating melons, your dad stared at them on purpose today, and didn't cut them open!"

She and her father are accustomed to eating melons and cutting them into pieces. When her daughter gets older, she likes to hold them in her arms and dig them out with a spoon. She has made many suggestions on this matter.

"Your mother specially left the uncut ones for you!" Wu Jingzhong added helplessly. It was clear that his wife loved her daughter just as much, so he had to add it so harshly.

"Mom, if you hurt me, you have to speak out boldly. If you don't tell me, how will I know? You can't be shy!" Wu Tong stopped the collapse of seeing his father again, and suggested boldly and playfully.

She turned the spoon and scooped out a piece of the sweetest melon core and put it into her mother's mouth, and then she also scooped out a piece for her father without any discrimination.

At the age in the dream, she was used to her parents' unreserved and unrevealed preferences. Instead, she had more and more conflicts with her parents because of some superficial discipline. She was unruly and willful, ignoring these day after day. His love is really undeserved!

Caring and filial piety is what she should be.

"Why are you so weird? I eat your food honestly. This is just one plate. Isn't it enough for me and your father?"

With a stubborn reproach, Jin Yu finally swallowed the extra sweet melon in his mouth.

The whole family and He Lele were eating watermelon, thinking that Wu Tong was startled, and the couple didn't think much about it. They didn't ask Wu Tong why he was startled. After getting close to his daughter, Mrs. Jin, who was in a good mood, specially Let Wu Jingzhong go to the street and buy a catty of beef in clear sauce that his daughter loves to add to the noodles for the evening.

The weather is hot in summer, and I have no appetite and can’t bear to eat hot food. The refreshing cold noodles are the Wu family’s daily dinner in summer.After urging his father and looking at his mother, Wu Tong did not return to his room until he had eaten, washed up, and watched the news broadcast that Wu Jingzhong would not miss.

Study hard and start from now on!

Picking up the pen, Wu Tong continued working on the math paper he had worked on in the middle of the afternoon.I guess I want to give some warning to the students who are flying kites during the summer vacation. The question of pulling the string of a flying kite is still a bit difficult.

Especially for Wu Tong, who was no longer concentrating on studying in the second half of her first year of high school, it was a little difficult to do it. The extra memories could only give her more warnings about the future, but they would not make her omnipotent, or even Some clutter and distraction.

When studying, I am most afraid of not being able to concentrate, being unable to devote myself wholeheartedly.

What Wu Tong is doing is a set question, which is the knowledge point that she has the weakest grasp of.

It is known that the complete set U=R, the set M={x∈Z|-1≤X-1≤2}, the relationship Venn diagram of N={x|x=2k, k∈Z} is shown in the figure, then the figure The shaded part in shows how many elements are there in the set?

Frowning her brows, Wu Tong thought hard. She still felt like she had no idea how to start. Even the symbols for the collective questions were a bit unfamiliar. She was distracted in class, had a weak foundation, and could only stare at the questions during the exam. This was her true reflection now.

Having no ideas for a long time can easily make people feel discouraged and irritable, and they can even feel a little upset and anxious. Are they not the right people to study?

The air conditioner was whirring, bringing coolness to the room, but for the anxious Wu Tong, it was really a drop in the bucket.If only there was something that could make her concentrate and focus on nothing else!

Just when he was about to complain that he was restless and still dreaming before he fell asleep, suddenly, a cool and peaceful feeling slowly spread from the depths of his mind, making Wu Tong feel as if he was a frozen watermelon in the dog days of summer, feeling extremely light. Spiritual spirit.

In just a short while, the problem that had troubled Wu Tong just now was vaguely grasped from her limited knowledge base, and she had some ideas. It seemed that she could start with the intersection operation of M and N sets.

This is, pie in the sky?

Or, her delusion?

If it was an illusion, the problem-solving ideas that emerged in her mind were not false. This was a knowledge point that the teacher had taught in the previous class. However, she did not listen carefully and her memory was vague. She was so anxious just now that she could not remember it. During that period of calmness, Her quiet concentration allowed her to focus without distraction. The knowledge points that she had heard before were dug out in depth, and they were connected from point to point to form a problem-solving idea.

To describe it in one sentence, this is called the spark of inspiration.

If possible, Wu Tong certainly hopes that this is real and not a one-time existence.In order to verify, Wu Tong calmly reviewed the problem again, and the clear spirit of Fu Zhi's soul emerged again. All the distracting thoughts in his mind were reduced to his legs, and he could only concentrate on solving the problem seriously and follow the ideas just now.

The set shown in the shaded part of the figure is MnN...

∵M={x∈R|-2≤x-1≤2}={x∈R|-1≤x≤3}，且N={x|x=2k，k∈Z}，

∴MnN={0}

Therefore, there are 2 elements in the set shown in the shaded part.

After writing down the whole thing smoothly, the answer was born in the pen. Wu Tong really experienced the joy of doing the questions.

If learning is so comfortable, learning all the time is a joyful enjoyment, not a torment of anxiety!

How many people's longing for such a wonderful pen!

The sudden encounter made Wu Tong curious and confused, where did this come from?Recalling that the original source of that magical feeling came from the depths of his mind, Wu Tong couldn't help but close his eyes and calm down, concentrate his thoughts and feel it deeply in the depths of his mind.

Her heart calmed down inch by inch. Suddenly, Wu Tong only felt that her own consciousness came to a magical place, her thoughts were clear, and a burst of enlightenment came to her heart. This is the deepest part of her sea of ​​consciousness. Among them, a The slightly incomplete black jade tablet stands quietly, even if the body is incomplete, the jade tablet is still radiant, moist and crystal clear.

Wu Tong's consciousness tentatively approached the jade stele, and she was enveloped by the calm and mountain-like aura of the jade stele. A warm current flowed quietly into her heart, and all the consequences naturally emerged in Wu Tong's mind.

There is a strange thing in heaven and earth called the Enlightenment Stone. It is a natural monument and has the miraculous effect of comprehending the principles of heaven and earth.It’s just that time has passed and the years have changed. Today, the broken Enlightenment Stone has only the weak ability of Ning Xin to concentrate on assisting thinking operations and deductions, and it is on the verge of extinction.

Today, being activated by the intertwined energy of time and space, Wu Tong, as the owner of the property, was unexpectedly able to blend in with the future and get a glimpse of the future.

But for Wu Tong, these minor abilities are already extremely useful aids to her. Being able to obtain these is already her blessing. She is not greedy to reach heaven in one step and become an immortal or a Buddha.

It is enough to study step by step, master more knowledge, become the pride of your parents, become a useful person, and be able to control your own life.
