In the living room, the two mothers have a good talk. In the room, Diandian and Liu Yu sit face to face at the desk to do their homework. The two little guys have no idea that they have been decided by their respective mothers.

Liu Yu looked at the exercise book, did not write a word, began to doze off, closed his eyes, small head bit by bit, chin knock on the table, people immediately wake up. When Liu Yu rubbed his eyes with his little hand, he saw that the opposite spot was looking at his winter vacation homework, and a trace of pity flashed in his brown green eyes.

Liu Yu along a little bit of vision to see in the past, it was found that their winter vacation homework is open, in addition to a few drops of saliva, a blank.

"This... This is for a reason, I can explain..." at the moment, Liu Yu want to cry heart all have, flurried winter vacation homework closed.

He doesn't want Diandian to know. He can't do his homework at all.

Diandian said, "write quickly." Then he lowered his head and began to write.

Although Diandian and Liu Yu are now in small classes in kindergartens, because they are in one of the best international bilingual kindergartens in Beijing, in order to highlight the particularity of this kindergarten, in line with the principle of not letting children lose at the starting line, they usually play and study in kindergartens. In the first winter vacation, teachers leave some winter vacation homework.

Liu Yu raised his neck and looked at Diandian. Seeing that Diandian was full, he opened his mouth with admiration and admiration, and said, "you are so powerful!"

Nodded and said: "nothing serious, these are very simple."

Liu Yu did not speak, he felt very difficult, he did not understand, let him sit here for another hour, he still can not, so, might as well read a little bit of homework.

So, Liu Yu has been half lying on the table, holding his neck to watch Diandian's homework. When Diandian has finished all his homework, Liu Yu still keeps this action unchanged.

Dot saw an eye, Liu Yu still a blank winter vacation homework, frowned, asked: "why don't you write?"

Liu Yu's mouth slightly moved, did not mean to speak, pinched half a ring, he just whispered: "there are a few questions I can't write, can you teach me?"

Dian Dian asked, "which ones?"

Liu Yu stretched out his finger and pointed to several questions randomly.

Diandian put his head together and saw that they were all addition and subtraction problems within ten, which he could do before he went to kindergarten. However, looking at Liu Yu's pathetic face, Diandian didn't say anything more.

Diandian said, "I'll teach you!"

Liu Yu's big eyes lit up immediately and nodded heavily.

ten minutes later.

Dian Dian asked Liu Yu: "this, do you know it?"

Liu Yu anxiously grasps the ear, "seems to be meeting a little."

Dian Dian's face turned black. He has talked about such simple arithmetic problems as three plus two and two plus three four times, but Liu Yu only knows a little bit?!

Diandian really wants to knock Liu Yu's head open to see what's inside. It's clear that three plus two and two plus three are equal to five. Why doesn't Liu Yu understand?!
