As soon as Lu Zitong saw this list, she cried. She has always been the first in her class. This time, she actually dropped two places at a time. She can’t accept such a result.
He Lianyin is also a little shocked. Looking in the direction of Yu Zhou, there is an unknown horror in his eyes that Yu Zhou can actually get the second place in the exam. Is he like himself …
Sitting in the first corner, Yu Zhou smiled at her, her eyes were shallow, her nose was pretty, her hair was brown, and she looked like a hybrid.
His eyes were also surprised. It seems that he also has some questions to ask He Lianyin.
Eye contact block dinosaur has let go of chalk Gherardini way "HeLianYin Yu Zhou you two stand up"
Two people in accordance with the words.
"You two answered the last big question in the math test this time. Zhou solved the first part and got 7 points. Yin got 7 points. Two students deserve to be encouraged to applaud."
Class applause
They all turned the test paper to the last question, and sure enough, everyone was red.
"Good boat classmate sit Yin classmate you are like to solve this problem? Please tell us something about your train of thought. "
The class suddenly became quiet, and even the flipping of test papers stopped.
"It’s my fault to solve this problem." Even Yin Yin is very quiet.
Ban outcry
Dinosaurs don’t so smile at her "oh? Let’s hear it. "
"It is difficult to calculate the result of this problem only by junior high school knowledge points. I have participated in the high school mathematics competition and seen this problem. The point of attention is induction. First, write the series. A general formula reflects the special to half thinking laws. For the series with complex item structure, we can divide it into several parts and then combine them according to the operation rules to solve this problem."
He Lianyin was fluent in words and told the whole step again. Looking back, the dinosaur has shown appreciation, and her appreciation of He Lianyin has risen to another height.
The students’ eyes also showed shock and admiration.
"Yes, Yin is very reasonable. This question is beyond the junior high school level. The students are not too discouraged when they answer it normally."
In fact, the results of the first three students are very similar, and the difference is only due to the study of the boat. Some steps can be deduced from the knowledge of the high school. Lu Zitong did not touch the high school level and could not solve it. However, the level of Helian Yin’s participation in the competition is naturally a little higher than that of the two.
He Lianyin was so angry that she met such a problem before running for class cadre, so her gorgeous classmates stood tall.
It seems that luck is still very important.
If this luck is changed to ten points in the college entrance examination, it will be a fatal point.
He Lianyin looked at the back of her head and didn’t know what he was thinking. He looked boundless and said nothing.
He didn’t even get a note from someone else, and he supported Bafa.
Lesson one
There are a few students to comfort Liu Zitong, and there are also a few students who come over with test papers and ask Helian Helian to look at the test papers in their hands and give directions appropriately.
She is famous.
Secular is such a reality. If you are good, everyone will surround you. If you are bad, everyone will stay away from you.
Yu Zhouye stood out in the crowd. "You just spoke very well."
"not bad"
"You actually participated in the high school math competition?"
"Well, before Yunjiang, the teacher asked me to take the place of a high school student, but we were a small village, and we couldn’t get out of the encirclement." She looked at the other students’ papers with a serious answer and circled the key points with a ballpoint pen and said, "You can work out the steps by reversing this calculus …"
Section 72
That classmate was flattered. "Thank you for your advice."
He Lianyin smiled. "You’re welcome. Students should help each other."
The bell rang again.
It’s usually quiet. He Lianyin cocked his head at this time and didn’t speak a word.
