After a pause of 2 minutes, Mr. Xu said, "Wu Zhenzhen, you get up and explain your second step." ”

Xiao Zhen got up and said: "The first step is to calculate the number of tickets is 428.57, so 428.57 people can go to the movie." ”

Teacher Xu said, "Okay, that's a great answer, but what do these 428.57 votes and 0.57 people out of 428.57 people mean?"

Xiao Zhen's head was also confused when he heard this, yes? What kind of ticket is this 0.57? And who is this 0.57 person? So he said, "I, I don't know, but it's like this." ”

Teacher Xu said, "Okay, you sit down first." Therefore, everyone must pay attention to this kind of topic, this ticket is one by one, and the incomplete ticket is a waste ticket. And people are also one by one, incomplete people, so I don't need to explain it. ”

As a result, laughter echoed throughout the class, and everyone leaned back in laughter as they looked at themselves or those around them who had written 428.57.

"Okay, so everyone pay attention, all the ones with 'individual' and Zhang as the smallest unit must be paid attention to by me, don't write me a decimal. Teacher Xu continued.

"Xiao Ai, what do you think about the second step, and also talk about your thoughts. Teacher Xu said again.

"That's what I thought, this one can't be divided, so it's all rounded up. Xiao Ai said.

"Well, that's right, but you can't round it up, for example, you can't get on the plane for 500 people, you can't get on the 501st person, because one more person on the plane can cause an accident on the plane. Again, 428.57 can only be rounded off the decimal here, because you only have enough money to buy 428 tickets, and the conductor is mathematically impossible to give you 429 tickets. Teacher Xu continued.

So, all of a sudden, everyone was deeply impressed by the topic that Mr. Xu said, and they were also impressed by Mr. Xu.

"Okay, whoever makes this mistake next time, this application question will be scored, I'll make three chapters of the law today. Teacher Xu continued.

And the children agreed to this agreement.

Because this math teacher has a good grasp of the key, everyone's math has also improved.

And after class, it gradually became a popular idol to communicate with each other.

In school, Xiao Zhen found that everyone couldn't finish talking about the topics of "Star Academy" and "Super Girl", but Xiao Zhen's information seemed to be relatively small, so the communication was always based on listening.

So, Xiao Zhen decided to increase the time to watch TV, and the nap time at noon every day seemed to be good. Although, the real mother always says that insisting on napping is good for the body or something, but the time for Xiao Zhen's serious nap has been pitiful, and it is even more impossible to have a plan now.

As soon as I got home at noon, after eating, and my grandparents went to bed after reading the news, Xiao Zhen began to press the remote control to find "Super Girl" and "Star Academy" related content.

After all, the news found at this time can immediately become a talking point in the afternoon.

However, rummaging through the pages does not seem to find very valuable entertainment news.

In the end, after turning to the central 10 station, Xiao Zhen was attracted by a column called "Hundred Lectures", and Xiao Zhen became the first audience of Professor Yi Zhongtian's "Han Dynasty Figures".

Watching Professor Yi Zhongtian's colorful speech, Xiao Zhen gradually developed a strong interest in history.

As a result, jumping on the platform between "Star Students", "Super Girl", and "Hundred Pulpits" every day has become a small and real hobby. And the replay of "Hundred Lectures" in the evening was very late, so Xiao Zhen basically contributed his nap time at noon to "Hundred Lectures" since then.

Lao Wu occasionally went home at noon to find Xiao Zhen watching cultural programs, and he was also very happy.

And in the "Men of the Han Dynasty" broadcast at this time, the first thing to talk about is Han Xin.

As the show deepened, Xiao Zhen temporarily threw "Romance of the Three Kingdoms" aside, and instead turned up a story book describing the semi-history and half-fiction of the Chu and Han dynasties from his grandfather's old bookcase.

At 12:45 p.m. every day, Xiao Zhen sat in front of the TV, seriously savoring the wonderful explanation of Mr. Yi Zhongtian and took notes. The story.

After reading Han Xin's content for a few days, Xiao Zhen picked up his notes and began to think:

On the one hand, Han Shin began to wander the streets with nothing to do from the beginning of the ruined aristocracy, and endured his heart after experiencing the humiliation of his crotch, and the dramatic process of awakening after the grace of his mother's meal made Xiao Zhen interested in Han Shin.

Next, Han Xin became Xiang Yu's guard and felt that there was no way out, so he switched to Liu Bang, and later found that there was no way out for Liu Bang and prepared to escape, which made Xiao Zhen understand - sometimes although he has ambitions, it is difficult to succeed without appreciation.

However, after Xiao Heyue chased Han Xin, Han Xin's fate took a fundamental turn, and he suddenly became one of the real protagonists in the Chu-Han War, and his reputation completely overshadowed another Han Wangxin of the same name in the same period.

However, Han Xin's forcible request for the title of King of Qi in Qi has laid the root of the bane.

In the end, the process of being moved to Chu, demoted to the Marquis of Huaiyin, and dying at the hands of Xiao He and Lu Pheasant made Xiao Zhen feel very painful and helpless.

In the following period, as long as he was free, Xiao Zhen thought every day, why did Han Xin leave after becoming Xiang Yu's bodyguard? After all, Xiang Yu really lacked a military talent who could stand alone, and as long as there was a real war, Han Xin would also have a chance to take the lead.

After running to Liu Bang's account, no matter what Han Xin did, he was the person behind Liu Bangpei County Group.

When Xiao He chose Han Xin, he really found that Fan Xu, Cao Shen and these people could not really change the fate of the Han Dynasty.

Why didn't Han Xin choose to ascend the throne himself? After all, Liu Bang's suspicions were not once or twice, and Xiang Yu's morale was already low, so there was nothing to worry about. This period is completely favorable for Han Xin.

Why did Han Xin behave so naively in the position of King of Chu? Han Xin clearly knew that after he was named King of Chu, Liu Bang did not sleep well every day.

Could it be that Liu Bang's words of "seeing the sky and not dying, seeing the ground and not dying, seeing the light and not dying, seeing the blood and not dying" made Han Xin let down his vigilance? Xiao Zhen naturally didn't believe it.

After being demoted to the Marquis of Huaiyin, why did Han Xin still talk about self-righteousness? Already within Liu Bang's control, why didn't Han Xin know how to restrain himself? Xiao Zhen was puzzled by Han Xin, who took the initiative to take one step and one step closer to death.

If Han Xin paid a little attention to his work, he would not be easily killed by Lu Pheasant and Xiao He.

Han Xin was changed from the king of Qi to the king of Chu by Liu Bang step by step, and then from the king of Chu to the marquis of Huaiyin, and finally the whole process of death and annihilation seemed to be that Liu Bang kept wrapping layers of bandages around Han Xin until he finally lost his breath.

When Xiao Zhen thinks of this, he often thinks of what Cao Cao said when Lu Bu was arrested: "The tiger has to be in a hurry." ”

However, Han Xin is a loyal minister after all, although he seems to have offended Liu Bang sometimes in language.
