Just looking at the options, he was a little dazzled.

Accustomed to the short, flat and fast mode, the first question of the league this time made him a little uncomfortable.

At this time, the benefits of rich experience and a solid foundation emerge.

If the topic is long, you have to find the key information, and then directly ignore the nonsense of the topic, simplifying the complexity.

So, what is the key message of this question?

Lu Shixian quickly circled the four characters of gene expression on the test paper.

Relevant knowledge points about gene expression quickly emerged in Lu Shixian's mind.

Gene expression process: gene transcription forms rna → rna translation forms protein → protein participates in metabolism.

So the order of omics is: genomics→transcriptomics→proteomics→metabolomics.

Although Lu Shixian knows it in his heart, for this question, if someone does not know what omics is and cannot determine the position of genomics, it does not affect the answer to this question as b.

But if you are not proficient enough to even master the most basic knowledge of gene expression, no matter what skills and experience you have, you are farting.

So this is a multiple choice question.

This is life competition.

While setting up the barrier gate, it opened a window for you.

Compared with the preliminaries, the test questions of the league have indeed improved a lot.

Even Lu Shixian had some difficulty doing it.

It's not that I can't do the topic, and I don't have a clue in my mind.

But there are too many questions, and 120 difficult questions are completed within two hours, which also includes the time for reviewing questions, answering and painting answer sheets.

So it's very difficult to do it all at once, and it's impossible not to get stuck in the middle.

This process is actually a double test of people's mental and physical strength.

Lu Shixian chooses to pick questions to do, and after finishing the brush, he can directly select the answers to the sub-questions, and Lu Shixian turns around to do those questions that need to be calculated.

At 11:30, about half an hour before the end of the exam, Lu Shixian was undecided on the last 6 questions.

All are multiple-choice questions, and some questions are really easy to play with some word games. Even if you know the knowledge points, there are always one or two options that are a bit vague.

There are not a few such questions. Lu Shixian feels that if his Chinese is not good, the questionable questions are far more than these six questions.

Judging from the past situation, if the theoretical questions with a total score of 150 points, you can get into the provincial one with 120 points in the test.

If you want to enter the provincial team, if the experiment is performed normally, you may need a base of 130 points to be considered safe.

But for biological leagues, this statement is not entirely accurate, because the final ranking is based on weighted t-values.

Even if your total score is higher than others, there is still the possibility of being reversed in the end.

At this point, some contestants have already handed in their papers one after another.

Lu Shixian didn't panic, he wrote down the spare answers to these six questions on the scratch paper, and began to check the filling of the answer sheet to see if there were any omissions or mistakes.

In the last 20 minutes, after careful consideration, Lu Shixian found one of the multiple-choice loopholes and corrected his answer.

In the last ten minutes, Lu Shixian chose to be decent, and chose to fill in the spare answers on the answer sheet.

Now that the matter is over, Lu Shixian doesn't have to struggle anymore.

Putting down the few questions that he had just pondered over, he felt that he should be more stable this time according to the feeling of doing the questions.

Thinking about going back and reading the content mentioned in those questions again, Lu Shixian found his schoolbag and left the middle school very calmly.

Back in the classroom again, the class was already explaining the three-mode test questions. Lu Shixian suddenly felt that he was a little redundant, and he didn't participate at all.

Review the content of the college entrance examination or continue to study students?

forget it!

Hearing the loud lecture of the teacher on the stage, instead of being disturbed to do some inefficient things here, it is better to go out and relax.

There is one thing to say, before the league, he was really under a lot of pressure, after all, the more he cared, the more worried he was.

Now that the exam is over, let's combine work and rest to be lazy, no one will have any objections.

But as he walked, Lu Shixian unexpectedly walked to the door of the classroom of Class 1 (1) of Senior High School inexplicably.

"Today we start to study life systems, do you know that the most basic life system on earth is the cell"

Hearing the voice inside, it looks like he is still in biology class?

He just got used to it and wanted to step in, but then he found helplessly that he didn't seem to belong here anymore. His classroom was on the third floor.

But he suddenly remembered that his student status was still here, and from a system point of view, he still belonged to Class 1.

Now, Lu Shixian no longer has any psychological burden.

So he sneaked in from behind.

At this time, the voice of biology teacher Wen Shaoying was lecturing.

"Our class is about the structural level of the life system. Now I invite a few students who are previewing to help explain the specific content without reading the book.

Suddenly a boy was pointed up with an ashen face: "It should be cells, tissues"

Talking and talking but nothing more.

Wen Shaoying's old face suddenly pulled down.

"I told you before that it is not enough to rely on the teacher to learn biology. With so much content, you have to learn to learn on your own initiative."

"Now I'll click on one and let me see how many people haven't previewed? Next!"

"Cells, tissues, organs, systems, uh"

"Next!"

As more and more people ordered, Lu Shixian panicked.

No way? so unlucky? Is it really such a coincidence to drop by at last?

Just happened to meet the teacher to ask the roll call.

He quickly lowered his head, praying that Teacher Wen could not see him.

But Lu Shixian forgot a truth, the more concealed, the easier it is to arouse suspicion.

What little tricks the teacher can't see while standing on the stage?

Sometimes not debunked is just too lazy to say it.

So now it arouses Wen Shaoying's anger instead. I have to say that sometimes the older you get, the more stubborn you become.

He suddenly pointed to the last row and said.

"This classmate, if you can't do it, you can't do it. What does it look like hiding? Stand up for me."

Now, everyone looked in the direction of the finger, and all the people who were affected halfway leaned back to avoid this direction.

"Hey, isn't this place used to put books? When was there an extra person?" Someone asked doubtfully.

As the students in the penultimate row moved out of the way, Lu Shixian had nowhere to hide.

"I go!"

"Squad leader?"

"Lu Shixian?"

There was a surprised and unexpected voice in the class.

Lu Shixian showed an awkward yet polite smile, secretly glanced at the reactions of his classmates, and then said.

"I think I should know the answer."
