Chapter 399

Not only the people in No. 7 middle school were stunned, but even others were stunned.

Lin Wushuang is the last one to play!

Unexpectedly, he killed several other groups. What's more ridiculous is that the second middle school, which has been leading, didn't do it in this problem card for 10 minutes!

Lin Wushuang went up and finished it?

I'm afraid the reading has not been completed.

So someone questioned, "does Lin Wushuang know the answer in advance? I didn't finish reading the topic at this speed."

"Yes, or I met the questions I had done before. Didn't the teacher give us Lin Wushuang's questions yesterday?"

"If so, it's not fair at all!"

The teacher smiled, and it was normal for everyone to question. After all, Lin Wushuang's speed was really frightening. "OK, let's continue to answer the questions first. Although only the first completed group has extra points, we have to do things from beginning to end. The rest of the students finish the questions first, and then we will analyze these questions."

The teachers spoke, and there was nothing we could do. Those who were still competing had to calm down and finish the competition first.

After all, if Lin Wushuang really cheated and the first place was cancelled, the second place would have to top up, so now the competition for the second place is also very fast.

Five minutes later, the last one finished. The order of completion is: No. 2 middle school, No. 3 middle school, No. 1 middle school and No. 4 middle school.

"OK, it's all finished, so let's go back to our seats and the teacher will analyze these questions for you." the teacher opened the questions of all groups and displayed them on the computer.

"Eighty percent of the questions here are given by the training teachers, and only 20 percent are last year's questions. They appear in each team. No. 1 middle school is the fifth question, No. 2 middle school is the third question, No. 3 middle school is the eighth question, No. 4 middle school is the second question, and No. 7 middle school is the fifth question."

"According to my observation, when No. 1 middle school, No. 3 middle school and No. 4 middle school were doing last year's topic, they happened to be sophomores in senior high school. Fortunately, you did it soon."

"Only two middle schools and seven middle schools were two senior one students when last year's problems appeared."

Miao Xinrui was the subject of the seventh middle school last year, and it happened to be a multiple-choice question. The four answers were wrong three times.

"As for multiple-choice questions, there is one for each team. I won't say more about this."

"Then let's look at the last question Lin Wushuang did. The difficulty coefficient is five stars, and this question is the one given by a training teacher in the second middle school. I think Lin Wushuang should not know the answer in advance."

Even if you know, it should be from No. 2 middle school.

Everyone was speechless, but there were still some doubts about Lin Wushuang's speed.

Someone said, "since Lin Wushuang didn't cheat, go up and tell us the idea of solving this problem and how to calculate the answer."

No one has worked out the answer to this question since the teacher put it out again for everyone to see.

So I directly began to ask Lin Wushuang what method was used and gave the answer in a few seconds?

This is a five-star problem. It takes a minute or two to write a draft with a pen, not to mention oral and mental arithmetic.

And there are more people who haven't even found the way to solve the problem.

Seeing someone ask such a question, the teacher asked, "Lin Wushuang, would you like to come up and tell us the idea of solving the problem?"

"OK!" Lin Wushuang went directly to the stage, picked up a special pen and began to write the solution ideas on the display.

She writes very fast, but the words are very beautiful.

The solution only gives the operation mode, saves the cumbersome calculation steps, and gives the answer directly.

Then he said to the whole class, "I don't think I need to calculate it for you step by step?"

So someone immediately took out the draft paper and began to calculate, and the pen quickly wrote on the paper. However, the idea of solving this problem is cumbersome, and the number of operations is large, so it can't be calculated for a while.

He as like as two peas, who used the shortest time or he Yan, the last answer he calculated was exactly the same as Lin.

Then, more people calculated it again and again. The answers were the same as Lin Wushuang. There were only a few calculation errors, and the answers were different. Recalculate.

"This..."

Now everyone has to admire it.

How strong is Lin Wushuang?

"It seems that everyone is convinced of this small competition. Now I announce that ten people in No. 7 middle school will each add one point of credit. Well, in the next time, I'll tell you about these questions..."

All morning, everyone studied around these topics.

Take these questions apart and draw inferences from one instance. Passion is led to the highest point. Time passes quickly, making everyone closer and closer.

"I don't feel tired all morning. Why do I feel so tired at this time." Qiu Ge didn't have strength when eating. "I have to continue in the afternoon. Suddenly it seems to rest."

"That's because I worked too hard in the morning," Dong Wei said. "But the training is really fun. Many topics are challenging. One person in our class is too strong and we can't surpass it. Otherwise, our enthusiasm may be higher."

Lin Wushuang: "... Shall I let you this afternoon?"

"Don't let it," He Yan said. "After all, you let it, and they can't surpass me here."

Braised pork in brown sauce. "Hello, old fellow," he said. "I won't believe it. I can't get over you. I'll go all out and work hard!"

After dinner, it's lunch break.

Now there is no mobile phone to play. It's really boring. Some people go to bed when they go back to their bedroom, but some people can't sleep.

Lin Wushuang belongs to the kind who can't sleep. After all, she has room to sleep at any time.

So I put down the shading mosquito net at noon and planned to run out to play.

Seeing this, Yunhui asked, "Lin Wushuang, why do you turn off the mosquito net at noon? Don't you think it's dark inside?

"It's just to be dark. You can't sleep without it." Lin Wushuang said, and asked Le Xin to come out and release points. He went directly back to Qingcheng's home through the portal.

There is a tablet at home, you can brush the video play time.

……

In the bedroom.

Yunhui thought it was strange, "I bought a shading mosquito net at night when I study, which doesn't affect others, while Lin Wushuang bought a shading mosquito net to sleep at noon?"

"What do you care about others? If you can't sleep, brush the questions. Come on, give you a coke." Ding Tian apologized for wronging Yunhui and sent a bottle of coke to Yunhui.

When Yunhui saw the coke, she remembered that she still owed Lin Wushuang a can of coke and immediately smiled, "Oh, your coke is good. I still owe Lin Wushuang a can."

Then he said to Lin Wushuang's bed, "Lin Wushuang, I'll return the coke for you."
