I told the teacher of Class 4, Mr. Xu, that his girla female student of his smoked, and showed him the footage.

He went to talk with the girl, but he came back soon after and asked me to send him the footage, because the girl had denied it.

Then I told Ms. Liu about the incident.

After the next class later, I aksked Mr. Xu why so many students in his class went to the Chairman Oprincipal's office.

Chairman = 校长？

He said that they were asked to bear witness tof last Friday's fight.

The boy's father wasn't satisfied with the resultschool's actions, so he came to discuss the fight again.

The boy said, "Mmy English teacher was just standing there and never helped."

Mr. Xu told him that if the English teacher hadn't helped you, you, he would have been dead.

Alternatively, "Mr. Xu told him, if the English teacher hadn't helped you, you would have been dead."

I felt ridiculous, and told them it was quite dangerous on-the-potright then and there, but I had still tried my best to stop the fight.

Then, I asked my students how many times I had separatedbroken up the fight.

Then I told them what the boy had said, and I regretted protecting him behinde me.

Still probably for the best that you did, I think.

My students said, who I that I had pulled away were the Nine Ga ninth grader, not him.

I was quite shocked, because it was really dangerous, I even did like that what I had done.

Then, I told my students, if they made trouble like this, I would never do athem any favours.

I would just stand and watch, and then askedcall for help.

You might have meant "I would just stand and watch them call for help."

ActuaTruthfully, I was quite afraid at that timefearful then.

I said it was because I was a teacher, and I had the responsibility to protect students.

As tTeaching them was boring, but I would still do my best, because I didn't want to just stand around and feel sorry for myself.

When we were talking theabout social media, a boy asked to read my diaries again.

I showed them the comment ofabout "闹翻天", but they denied it.

哈哈哈哈

I emphasizsed that they always behaved badly.

Make sure you're consistent in using British spelling.

I didn't tell them, that one of the boy even couldn't tells didn't even know my name today.

In the night class, I dictated the 26 letters for the fourth time.

To my surprise, several students made a biglot of progress, they all got the full score.

The three girls who had played strip poker included.

Connect to previous sentence with comma

Last time, a boy got a 0, but this time, he got full score.

I asked the boy sitting in front of mehim what had changed, he said that he was so afraid to copy the wrong letters again, that he had recognmemorised all the letters.

I praised them oin Pthe parents Ggroup chat.

I told the teacher of Class 4, Mr. Xu, that his girlone of his female students had smoked and then show him the footage.

He went to talk with the girl, but he came back soonhortly after and asked me to send him the footage, because the girl denied it.

Furthermore, he can't recognise all his students, either.

Then I told Ms. Liu about the incident.

She said that she had taught the girl for a year, so she definitely couldn't be wrongwas sure of it.
