Er Shao was a little embarrassed by Tong Tong and bowed his head to take the paper.

"Why are you wrong about this question, haven't I told you so many times, this kind of direct formula is just fine, I will write it down for you to see, the ring R-the radius of the outer circle, r-the radius of the inner circle, D-outer circle diameter, d-inner circle diameter, S = π (R2-r2), it ’s time to make a mistake next time. "

Tong Tong didn't even look at the paper, staring straight at Er Shao. She is already in her third year of high school. What does high school mean?

A girl who is over 18 years old has all kinds of organs fully developed. Let ’s not talk about the turbulent waves of Tong Tong, let ’s talk about her eyes. She has been a charming hook since childhood, let alone the long-haired shawl wearing only a small sling Mobo.

Er Shao's face was getting hotter and red, Tong Tong's body was getting closer and closer, and a faint fragrance hit his face. Er Shao's hand holding the pen began to tremble, and his heartbeat almost rushed out of his chest. Tong Tong laughed down on the table.

"you!"

Er Shao looked at her angrily, playing her? !

"No, Ershao, why are you so tempted to seduce?"

Tongtong pushed the matter to the second young man, and the second younger stopped talking and narrowed his eyes slightly.

Hey, why don't you talk, don't you really get angry? Before waiting for Tong Tong's exit, Er Shao stood up suddenly, holding both hands on Tong Tong's side, locking her in her arms and squinting at her.

Putting hands on Ershao's shoulders, Tongtong blushed next time, "What are you doing?", A very small voice with a little scared look, Ershao didn't eat this set, and snorted, Raised his right hand, hooked Tongtong's neck and kissed.

Well, it's already cooked very easily, very sweet and soft.

Tong Tong didn't expect the second youth to be so direct, his face flushed, and he wanted to push the second youth, but his hands were soft and unable to exert his strength. Tongtong was let go, jumped off his teeth, and his tongue followed.

"Um ... two young!"

Tong Tong blushed and pushed away the second young man with a blushing face, his hands covered his chest, his head lowered and gasped violently.

"Are you still in trouble?"

Er Shao also panted a little, but Tong Tong was angry with a calm voice.

"How can you do this?"

Tong Tong's blushing is not good, hey, who said that there should be no small movements to make up the class, what is it that you hold me like this and kiss?

Er Shao rubbed his hair and looked at Zitong lazily.

"Tongtong, you better not challenge my endurance."

"what are you talking about……"

Tong Tong bit his lip, Er Shao kept looking at her, and saw that she smiled awkwardly.

"Tongtong, read the book as soon as you know it. Don't think of any crooked ideas anymore."

"Where do I have a crooked idea!"

Tong Tong straightened his waist, and his meaningful eyes narrowed back when he played a pair of Er Shao.

"Other people don't know what's going on, will you still not know?"

The weather was a bit hot, and even the words spoken by Er Shao kept irritating Tong Tong's body with a trace of heat, and Tong Tong shrank subconsciously.

"What the **** ... I don't know."

"is it?"

Er Shao smiled and reached out to hook Tong Tong's chin and let her look at herself.

"I'll tell you if you don't know."

"I don't want to listen ..."

Tongtong hasn't seen such an overbearing second lesson in a long time, and he was so shy that he didn't know what to do. No matter how embarrassed Tong Tong is, Ershao hooked her chin, looked at her eyes, and said one word after another:

"I want you so much, so don't tease me in the future, do you understand?"

"..."

Tongtong's head was lowered into the soil, and his ears were red, without saying a word.

Er Shao saw her in such a good mood, let go of her hand, and shook the pen in her hand, saying:

"The next one, the cylindrical volume formula."

How could this be possible ... Tong Tong looked at the dizzying formulas on the roll. Second young you wolf in a cashmere sweater, the first color in the world / wolf.

"What are you thinking, give me a good back!"

Putting a palm on the back of the head, Tong Tong was angry and shouted at the neck and shouted the second younger, "Don't stop shooting, it's not easy to use!"

"Do you know if you don't work hard ?!"

"You think everyone in the world is as smart as you!"

"At least you are as stupid as you are."

"Hong Ershao, what do you say, who are you stupid, you say it again!"

"You said it yourself."

"..."

The purple dad and purple mom who have been watching TV in the living room look at each other. Are these two kids talking about an earthquake?

Half an hour later, Tong Tong bowed his head and wrote the question that Er Shao painted for her, and Er Shao had fallen asleep early on the side.

To finish the question honestly, Tong Tong looked sideways at the second young man. How did she learn it? Why can't I understand what the teacher said, and understand the second younger one? It ’s better to change the teacher to two less, and study when you are in a good mood.

However, really tired ...

Mosquitoes outside the window were buzzing, Tong Tong rubbed his head and eyelids and began to stick together. He looked at the two young men around him and squeezed himself hard. Tong Tong lowered his head and continued to recite.

Facts have proved that Tongtong is not a fool. After three months of hard work, he finally made progress.

Touch 250.

Two 484.

Three modes 546.

Although there is still a certain distance from Er Shao, one book is no problem, but just like that, the day after the third model score came down, Tong Tong shut himself into the house and cried for a whole day.

During dinner at night, Zi Da Zi Zi Ma looked at Tong Tong carefully, Tong Tong holding chopsticks stunned.

Still not working? Should we still be separated from Er Shao? They all blame themselves. Why did n’t they listen to her and work harder?

The tears can't help flowing down, and I think it's meaningless to live with Tong Tong when I think of being separated from Er Shao. Zi Da really wanted to tell Tong Tong that in fact not only love, but Zi Ma swallowed the words on the side.

"Tongtong, why cry? Didn't your teacher say that, you are also a miracle, progressing so fast."

Tong Tong didn't speak with tears, what's the use of progressing fast, she just wanted to be with Er Shao.

"What's inside, don't cry, girl."

Purple Dad was a little anxious, so his eyes shouldn't swell when he cried like this. Tongtong didn't care what the second old man said, whine that he was crying happily, the crying addictive doorbell rang, Zi dad jumped up and opened the door, and as soon as he opened the door, he saw a sigh of relief from the person standing outside.

"You are here!"
