"Solution: When the wave propagates to point P, the displacement of point P is zero and the vibration direction is downward..."
Lin Wei, who was writing the question, heard the phone vibrate and glanced at the screen.
The pen in her right hand didn't stop, she clicked on the keyboard in her left hand, and looked at the words without being distracted.
I want to go to Tsinghua University: Well, I have seen it.
I want to go to Tsinghua University: you saw it in the morning when you stretched your waist.
I want to go to Tsinghua University: boy, good waist.
After writing a big question, Lin Wei realized that something was not quite right.
is a cell phone.
After she replied to Jiangsu's news, her cell phone remained silent.
Unlock the screen, the chat page has not received any reply message. Chatting and chatting, it is called chatting when there is a back and forth. Jiang Su has no movement, and of course Lin Wei can't continue to sing a one-man show by herself. How stupid.
Just as Lin Wei was about to put away her phone, she caught sight of the message she had sent in the past.
day.
Lin Wei's first reaction was to withdraw, but the message had been sent out for more than two minutes, to no avail.
Under the intersection of regret and regret, she knocked her head on the desk with a thud.
When she does the questions, she does the questions, and when she is doing the questions, she chats with people in a good way.
She chatted and chatted, and when she was chatting, why did she molest people for no reason.
The more Lin Wei thought about it, the more embarrassed she became, and she couldn't help but knocked her head twice.
The sound of knocking was a little loud this time, which attracted many people's attention. Even Bai Jian, who was holding his mobile phone and devoted himself to raising his boyfriend, turned his head: "Weiwei, what are you doing?"
Lin Wei snorted, met the gazes of many of her classmates, blinked her eyes, picked up another math book, put it on the physics book she had just knocked on her head, and continued to knock it three times. : "Worship the textbook and beg for a good score in the next month's exam."
The front desk looked suspicious: "Does it work?"
The play has come to this point, no matter how hard the sand sculpture is, she has to bite the bullet and finish singing. Lin Wei slowly took out the chemistry book from her desk pocket. Under the watchful eyes of more and more classmates, she calmly tapped three times. : "Whether it works, I don't know, anyway, I can take the first test every time."
As Lin Wei said, she continued to dig out her English book.
Who is Lin Wei? Grade 1.
Since she took the position of the first year of the year in the final exam of the first half of the first semester of high school, she has never been fired from that position again.
There is a saying how to say, the ranking of running water is the first year of iron.
The first class of students gradually began to waver, just knocked their heads a few times, in case it worked.
People are knocking every year, what qualifications do they have to continue to be stubborn
So, the first one, oh, no, now it's the second one, Lin Xiang, took out the math book that he had scribbled so he couldn't tell what it was, and thumped three times very reverently.
Then, there was a second person, a third person, a fourth person... Then, the first class of the afternoon was greeted with a thumping sound.
…
Whatever Jiang Su thinks or thinks, the five words "Young man, you have a good waist" are not too complimenting.
Like... flirting.
What's even more nonsense is that since junior high school, he was chased and confessed by various girls with notes, but he was molested... I'm sorry.
Jiang Su pinched his slightly burning earlobe, cleared his voice, held the phone expressionlessly, and responded to the news from an hour ago.
…
Lin Wei saw Jiang Su's WeChat after returning from the toilet with Bai Jian during the recess of her first class.
SU: Have a vision.
A question mark slowly appeared on Lin Wei's forehead.
Fortunately, she was accustomed to Jiang Su's abbreviation function, so she slowed down for a few seconds and understood what he meant.
Dare to love him, this is to praise her for her vision.
The reason why she praised her was because she thought his waist was good.
Lin Wei murmured, "narcissism."
Lin Wei actually didn't want to go back to Jiangsu news, but she thought about it, it seemed a little inappropriate for a well-behaved, sensible and worry-free three-good student like herself to pay attention to a teenager's waist inexplicably.
Although she felt that it was not a problem to pay attention to the waist or even to doubt the personality orientation. After all, the current high school students are not as simple and ignorant as everyone imagined, but she still felt that it was necessary to make herself as stupid as possible.
Lin Wei thought for a while and decided to explain to Jiang Su.
I want to go to Tsinghua University: I didn't mean to see it.
I want to go to Tsinghua University: The main reason is that your skin is too pale, and the waist line is very good, and people notice it all at once.
There was no movement on Jiang Su's side.
Lin Wei's phone vibrated when it was almost time for class.
SU: I remember it quite clearly.
Lin Wei: ? ?
Three seconds later, Lin Wei looked at the "white skin, good lines" she posted on the screen, and opened her mouth.
Yes, it's getting darker and darker.
…
After replying to the news, Jiang Su raised his hand a little uncomfortable and rubbed the tip of his nose.
After a while, he touched his neck a little uncomfortable.
day.
He was actually praised by the next door... shy.
