Lu Fei felt that the first tutoring was very beneficial, and he now fully understood what trigonometric functions were all about. He looked at Lin Xiaorou, who was talking with a dry mouth, and said sincerely: "Xiaorou, thank you very much." ”

Lin Xiaorou smiled slightly, feeling quite embarrassed, she talked about middle school math all morning, and she felt that she was tutoring high school students. She looked at her watch and asked softly, "Lu Fei, let me be a model for half an hour." ”

"Okay! no problem!" Lu Fei happily agreed, and said in his heart that as long as you tutor me in advanced mathematics, I will be a model for you all day.

Letting Lu Fei put on a thinking posture, Lin Xiaorou smiled and said, "Lu Fei, in order to make your expression more real, you might as well recall what you learned today." ”

Lu Fei nodded, motionless and began to recall the trigonometric functions he had learned in the morning.

Lin Xiaorou chose a place with a drawing board and began to paint.

Half an hour has passed, and Lin Xiaorou's painting of Lu Fei is no longer a faceless person, but a ...... Two more eyebrows. Seeing her progress, Lin Xiaorou was very happy, she beckoned to Zhou Ruolan, and said softly: "Ruolan, look, I can draw his eyebrows." ”

Zhou Ruolan looked at Lin Xiaorou's painting, then at Lu Fei who was posing, and nodded: "It's very similar, this is much stronger than what you painted last time, you continue to paint." ”

"Alas......" Lin Xiaorou bit her brush, shook her head and said, "I can't put down the pen, I still have to observe ......"

"Observation?" Zhou Ruolan looked up at the quartz clock hanging on the wall, and said with a bitter face: "I want to observe you here, I'm starving, I'm going back to eat." ”

Lin Xiaorou put away the drawing board and said with a smile: "I won't paint today, it's not something that can be drawn in a while." ”

Seeing that Lin Xiaorou was no longer painting, Lu Fei got up and said, "Xiaorou, Ruolan, I invite you to dinner to express my gratitude to you." ”

"Oh? Before Lin Xiaorou could speak, Zhou Ruolan rushed to answer, she was about to talk to Lu Fei about increasing the time for dance training.

"Ruolan, is this good?" Lin Xiaorou was a little embarrassed, because she felt that the mathematics she told Lu Fei would not help him in his exam at all, Louis XIV would not test the concept of trigonometric functions, that was the matter of the middle school teacher.

"It's okay, I'll treat you to a steak, how about going to Hawker?" Lu Fei asked.

"Lu Fei, you are still a big money. Zhou Ruolan smiled, "But it's too far away, I'm starving, or go to the nearby Pizza Hut, I happen to have a coupon, so I should save you money." ”

"Okay, that's it. But there are quite a lot of people there, so I'm afraid we'll line up now. Lu Fei said with a smile.

"Or ...... Forget it and go to the cafeteria to eat. Lin Xiaorou retreated again and let Lu Fei treat her, and she felt ashamed.

Zhou Ruolan had an idea, and said with a smile: "Don't worry about it, isn't there a home delivery service! I have a client for ordering food on my mobile phone, order food first, and then I'll change clothes after ordering, and let Pizza Hut deliver things here." When the goods arrive here, Lu Fei will pay again!"

"Okay......" Lin Xiaorou nodded, thinking about how to tell Lu Fei, his math was really poor...... It's too far.

After the three of them ordered some pizza and snacks, Zhou Ruolan went to the dressing room to change her clothes, she couldn't eat pizza in a ballet costume. Only Lin Xiaorou and Lu Fei were left in the huge dance room.

Lin Xiaorou frowned, and finally spoke: "Lu Fei, there is something I have to tell you, it is about your math problem. ”

Lu Fei nodded: "But it doesn't hurt to say it." ”

"You're pretty bad at math. Lin Xiaorou looked at Lu Fei's reaction as she spoke, and she found that Lu Fei's eyes had not changed, so she continued: "What I told you this morning is all middle school knowledge. ”

"Oh...... No wonder ......" Lu Fei suddenly felt in his heart when he heard this, it turned out that I didn't even understand middle school knowledge, no wonder I didn't know what the teacher was talking about in high math class. He looked at Lin Xiaorou, who was anxious, and wondered: "Xiaorou, what's wrong? I think it's very rewarding, after making up this knowledge, I can catch up." ”

"Alas......" Lin Xiaorou sighed and said bitterly: "Lu Fei, it's true that you have gained, but ...... Now that you're about to take midterm exams, what are you going to do? Can you catch up in such a short time?"

"This ......" Lu Fei couldn't help frowning, and said in his heart that this was indeed a problem, he looked at Lin Xiaorou, hoping that she could give some advice.

Lin Xiaorou is also thinking about this problem, Lu Fei's math is too bad, which is a good thing for her, a "tutor", because she is still competent in teaching those elementary math knowledge. But it was difficult for Lu Fei to get past the high math exam. Lin Xiaorou flipped through Lu Fei's notebook while thinking, and when she saw the example questions recorded by Lu Fei, Lin Xiaorou's eyes lit up, and she said with a smile: "Lu Fei, there is a way, how is your memory?"

"Memory?" Lu Fei was stunned for a moment, isn't it a little too embarrassing to be honest? Forget it, let's keep a low profile. He nodded and said, "It's okay, I can memorize words very quickly." ”

"That's good!" Lin Xiaorou bit her paintbrush excitedly and said with a smile: "When I go back, I will find you the compilation of the past exam questions, you can just memorize it, this is the hard work of the previous senior brothers and sisters!"

"Will the compilation of past exam questions work? Aren't they all the questions that have been examined?" Lu Fei wondered.

Lin Xiaorou smiled slightly, showing a confident expression, and said: "You don't know this, the exam questions in college are often repeated, I remember that when we took the high math exam, there were a few questions that were the questions from a few years ago, and they didn't change at all, and it would be no problem for you to memorize the test questions for a few more years!"

"Sounds good, do all subjects have such a condensed question set?" Lu Fei asked.

Lin Xiaorou shook her head and said: "There is no need for other classes, it seems that only the high math class has it, because Louis XIV's exam has to arrest people who fail the subject, so everyone will summarize his exam questions." He has been teaching mathematics for so many years, and he has to take exams every year, and he will not always come up with new questions, and he can memorize all the previous exam questions, and he can get at least 70 points. ”

Lu Fei was very excited when he heard this, and said excitedly: "Then it's decided, thank you so much." Xiaorou, can you continue to make up lessons for me in the future? I still hope to understand the high math class. If I want to go to graduate school in the future, I still can't avoid the hurdle of mathematics. In the national unified examination like the postgraduate entrance examination, I am afraid that there will be no more original questions. ”

"Well, don't worry, your math is on me!" Lin Xiaorou patted her chest, and the plump little white rabbit jumped happily a few times.

While the two were talking, Zhou Ruolan, who had changed her clothes, came back. Zhou Ruolan was wearing a purple silk dress, with golden eyes, and the aura of an intellectual senior sister was undoubtedly revealed, which was like the dancing elf just now. She came to Lu Fei, handed him a CD, and said, "Lu Fei, this is a ballet teaching CD, you have time to take a look, there is not much time before the New Year's party." We're going to have to step up our practice. ”

"Okay, I'll go back and have a look. Lu Fei took the disc and put it in the book, since he agreed to Zhou Ruolan to be his dance partner, Lu Fei felt that he still had to do this seriously, after all, Zhou Ruolan had found a very good math teacher for himself.

The three of them casually chatted about the school, and Pizza Hut's takeaway arrived. Two 12-inch pizzas, a few snacks such as fried squid and grilled chicken wings, plus three cups of milk tea and a plate of salad. The trio had a cosy lunch in the dance studio.

After the meal, Lin Xiaorou was thinking about continuing to let Lu Fei be her model, but before she could speak, Lu Fei's phone rang.

Lu Fei picked up the phone and looked at it and found that it was Cheng Yiqiu calling. Lu Fei habitually walked outside the dance room and connected the phone: "Yiqiu, is there something wrong?"

"Lu Fei, Sister Dongfang is home, if she doesn't come back at night, I'm afraid ......" Cheng Yiqiu's voice had a bit of a coquettish taste.

"Understood, I'll go over in a while, is there anything else?" Lu Fei guessed her mind and said bluntly.

"I didn't ...... Nope. That...... That...... Then you come early......" Cheng Yiqiu said hesitantly.

Lu Fei could guess from the sound of rapid breathing on the other side of the phone that Cheng Yiqiu's face must be blushing now, he smiled and said, "I know, I will be there in half an hour, I will be at school, soon." I hung up. ”

"I'll see you later!" Cheng Yiqiu immediately hung up the phone.

Putting away the phone, Lu Fei shook his head, and the silly girl seemed to be getting more and more cute.

He immediately said goodbye to Zhou Ruolan and Lin Xiaoju, and left the dance room.

Zhou Ruolan saw that Lin Xiaorou had been staring in the direction Lu Fei had left, shook her shoulders and smiled: "Xiaorou! are you a nymphomaniac again?"

"Not anymore. Lin Xiaorou said softly, "Ruolan, I have a good harvest today, I can draw his eyebrows." ”

Zhou Ruolan smiled bitterly: "You're stupid! By the way, I listened to a few words about what you said, how is it a trigonometric function?"

Lin Xiaorou nodded and said, "It's a trigonometric function, Lu Fei looks like he hasn't learned." Strictly speaking, his level of math is not as good as that of a middle school student. ”

"Wouldn't it?" Zhou Ruolan frowned, "Then how did he go to college?"

Lin Xiaorou put away the drawing board and said with a smile: "Maybe, but I don't have to worry about the lack of level as a tutor." As for his high math exam, he could only memorize the Louis XIV exam questions. ”

"I feel a little unreliable...... Zhou Ruolan felt a little bottomless in her heart, she looked at Lin Xiaorou with a confident face, opened her mouth, and swallowed the next words, Lu Fei's midterm exam is estimated to be enough......

Lu Fei naturally didn't know Zhou Ruolan's worries, so he sent the textbooks back to the dormitory and went straight to Fengya Villa. Looking at the closed door, Lu Fei withdrew his hand to knock on the door, he took out another key and gently opened the door.

As soon as he entered the living room, Lu Fei heard the sound of the TV. At a glance, he saw Cheng Yiqiu curled up in the corner of the sofa, she was wearing a beige cotton nightdress, her hands on her knees, and her two white and tender feet overlapped. Her eyes were closed at this point, and the remote control of the TV fell to the ground, apparently asleep.

Looking at Cheng Yiqiu's sleeping position, Lu Fei frowned, and he found that Cheng Yiqiu was trembling slightly.

Why doesn't this stupid girl know that she is covered with a quilt, it's not summer now, and she will catch a cold if she sleeps like this!

Lu Fei shook his head and walked to Cheng Yiqiu's side......
