The music class was taken over again

Qiaozheng wiped away the remaining tears from the corners of her eyes, her voice was still hoarse: "How did you find me today?"

Yan Ze turned his head and said, "My mother wants your autograph, and insists on making me chase you."

When Qiaozheng heard that he had fans, he was a little flustered. As a caring idol, Qiaozheng quickly said: "It's no problem if you want my autograph. You can sign as much as you want. I'll sign it now, sign it now." ? Why don't you sign my clothes, I'll give you this clothes..."

Yan Ze looked at China's idol with a strange look, took out the note paper that he carried with him, tore off a piece, and said, "You can sign this."

The tearing is not neat at all, the edges are zigzag, big and small, and the attitude is not correct at first glance.

He handed the pen to Qiao Zheng again.

Qiaozheng was holding the pen, and when the tip of the pen was about to touch the paper, her hand began to shake. She was so excited that fireworks exploded in her brain one after another.

Someone wants her autograph!

Qiao Zheng smiled nervously and excitedly: "My handwriting is not pretty..."

Yan Ze said lightly: "It's okay to have ugly characters, as long as you have a fan filter."

Qiaozheng put down her pen and laughed so loudly: "I... I'll go to the Internet to look up signatures in curly script..."

Yan Ze wanted to ask whether you would sign or not, but seeing Qiao Zheng's mouth shut in excitement, she swallowed the words back.

Qiaozheng found an online converter for artistic words, looked at a lot of fonts, and picked them up and down. This flamboyant one was good-looking, and that playful and lively one was also good-looking. She showed the mobile phone to the leader comrades: "This, this, and that, Which do you think is better?"

"whatever."

Qiaozheng complained: "Can you stop being so straight in your answer, and help me choose one."

Yan Ze just picked one at random.

Qiaozheng saved the picture, eager to try: "Give me the pen and paper, I want to practice."

Yan Ze had no choice but to tear a few sticky notes for her.

Qiao Zheng's hands were trembling, her eyes were fixed on the beautiful cursive signature on the screen, but the strokes she wrote were like crooked little reptiles.

Yan Ze couldn't stand it anymore: "If you want to write like this, you must not be able to write well. Only when you do it in one go can you write with charm."

As she spoke, she picked up the pen, and with a movement of the pen tip, the movements were smooth and flowing, and the two bold and unrestrained Chinese characters appeared vividly on the paper.

The more Qiao Zheng watched it, the more she liked it. The leader is indeed a leader, and even his signature is domineering.

Qiaozheng stacked another piece of paper on top of it, and traced Yan Ze's handwriting. Deliberate imitation was impossible to achieve the goal, so the words she wrote lacked a natural charm and seemed clumsy and naive.

After tracing a few words, Qiao Zheng became uglier and uglier. She was not a calm person, and she ran out of patience in a short time.

"I won't write!"

Yan Ze thinks that she is like a wayward child, she doesn't like impetuous students, if she encounters them, she must teach her a lesson severely and give a book copying package as a gift.

But Qiao Zheng was not her student.

"You don't need to do this, it's just a signature, you can write whatever you usually like."

But as a good Chinese idol with an idol burden of ten catties, Qiao Zheng felt that it would be too embarrassing for fans to see her handwriting so ugly.

There was a hint of coquettishness in Qiao Zheng's voice: "Then can you hold my hand and write?"

*****

Over there, the Hongmen Banquet of the Lei family is still going on.

How dare Xiao Zhang say that his father-in-law is not good, he quickly denied: "No, no, uncle, how dare I compare with you, I heard that the average score of the class you lead is the top in the whole grade."

The smile on Lei Xueming's face didn't increase much after hearing the flattering words, "Let's have an exchange, first tell me, how do you test this question?"

Xiao Zhang hesitated for a moment, and still wanted to struggle: "I... the topic I proposed is a sequence. But... I just started working, and I haven't figured out the rules of the college entrance examination questions yet."

Lei Xueming took a bite of the food and said, "My topic combines function images, vectors, and trigonometric functions... Let me tell you..."

Xiao Zhang couldn't cover his ears, he had to listen if he didn't listen.Lei Xueming's question is indeed a bit difficult, and it is estimated that three quarters of the students will have to fail.

"So," Lei Xueming paused, "I've been so honest, you should also tell me what's wrong with you?"

Lei Xueming was not so kind. He always kept in mind the No. [-] Middle School of Fire Prevention and Theft Prevention. The question he just mentioned was a nonsense, and it was not his question at all.

Xiao Zhang was honest and honest, but he couldn't be more coquettish than this old fox.

In a short while, it was fully explained:

The sum of the first n items of the arithmetic sequence {an} is Sn, and a2=8, S4=40, the sum of the first n items of {bn} is Tn, and Tn-2bn+3=0, (1) find {an} The general formula of {bn} (2) When n is an odd number, Cn=an, when n is an even number, Cn=bn, find the sum of the first n terms of {Cn}.
