Gu Sijia deliberately stood up and showed her way. "Teacher Li, I also go home every day to help my sister with tuition, and I want my sister to progress with me."

Gu Mai was stunned by the shocked eyes, Gu Sijia is really a scheming girl, when did she help her with her tuition? When she went home, she occupied all the desks by herself, so she could only find a small Mazha and write her homework on the edge of the kang.

Then Gu Sijia was still very worried, she would ask her questions, and after finishing her homework, she would go out to play with Zhang Xiaohua and Wang Xiaohong.

When did she help her with tuition? I dare to say anything big.

Teacher Li immediately praised. "Gu Sijia really deserves to be the top three students in our class, the deputy class president, while her grades are excellent, she doesn't forget to help her sister study together, which we have to praise."

In the class, there was warm applause.

Gu Sijia raised her cheeks, and she looked very glorious.

Gu Mai didn't bother to pay attention to her, and now it didn't make sense for her to expose her lies, and the teacher was probably willing to believe Gu Sijia.

It is better to use words to quarrel than to use strength to leave her behind, so that she has no chance to take advantage of her again.

Gu Mai asked the teacher directly. "Teacher, we haven't had an exam for a week, which day is there a test."

"Today...... We have tests, tests, and teachers have always liked to surprise and don't give everyone time to prepare. In this way, the test can be really carried out, which student will review carefully when he goes home, and which student will listen carefully in class. Therefore, everyone answers the questions well, no one is allowed to look at others, cover all the questions you have completed, and don't let others read them. Teacher Li directly took out a stack of mimeographed rolls and sent them down one by one.

The mimeographed roll paper is that the teacher writes the exam questions on the wax paper, the wax paper is very thin, there is a certain willfulness, and the wax paper will have fine lines in the process of writing, and there will be no breakage.

Therefore, when the teacher writes a set of test papers on wax paper, you can write it clearly.

Then put the wax paper on the white paper, brush a layer of ink on the wax paper, and the ink oil will flow along the gap in the wax paper to the white paper, so that a roll of paper is printed.

This piece of wax paper can be printed many times, which greatly improves the efficiency of the teacher's questions, and there is no need to copy the paper one by one.

This kind of printing technology was already very advanced in the sixties and seventies, that is, it could only appear in urban schools, and there was no such machine as the village school.

However, there are also disadvantages, that is, the ink will not dry easily, so when answering the question, there will be black ink left on your hands.

After Gu Mai finished typing the paper, he handed in the paper directly, and then began to rub the black ink on his hand.

The teacher frowned when he saw that the wheat handed in the paper so quickly. "Gu Mai, have you finished writing?"

It's only been 10 minutes, and this paper is required to be handed in in 1 hour.

Gu Mai said while wiping his hands. "That's it."

Teacher Li was still under the podium, monitoring everyone's answers, and he didn't care about the answers handed in by Mai, according to inertial thinking. "Gu Mai, even if you finish answering, do you have to check it well? See if you're right? You have to study like Gu Sijia, you look at Sijia, and the examination is very serious. ”

It's only been a few days since I learned, and only a limited number of people can learn it.

This kid ...... It's really child's play for learning, and I don't care about it at all.
