The students were all sighing: "We want to study hard now that school has started, but we don't know how to do the problems, and we don't know who to ask."

"What's most infuriating is that the answer is 'omitted'. If it's omitted, why am I even supposed to look at the answer! There's no internet in the teaching building, so I can't even check it on my phone..."

"Class monitor, come quick! We don't know how to do this, please help us!"

A jumble of cries for help arose, and everyone looked at Xue Yu expectantly. But then a female voice rang out from the side: "No need to ask the class monitor, I know how to do this problem."

The girl with glasses was overjoyed: "You know it? That's great! I can't remember this part. The underlined word in option B is '以'. The sentences are '御制诗以纪其事' and '日削月割，以趋于亡'. I can't remember how to use '以'."

Tongsu looked down at the question and said, "The first sentence '以' is interpreted as 'to,' meaning 'the emperor even wrote a poem to express this matter'..." Tongsu pointed to the paper, "The second sentence '以' is a sequential relationship, equivalent to 'and,' indicating the result, 'to the point of destruction'."

The girl with glasses thought about it carefully, then was overjoyed, repeatedly saying, "Yes, yes, that's it! How could I have forgotten!"

She hurriedly took out the wrong questions and wrote them down, then flipped to another question: "Then what's the difference between the word '者' in '四海好学能文者' and '非蛇靝之穴无可寄托者'? Aren't they both pronouns?"

Tong Su shook her head: "No, the '者' in the first sentence refers to a person, while the '者' in the second sentence is an auxiliary word that, together with the '也' in the following sentence, forms a judgment tone."

"Yes, it is indeed a particle. How could I forget again! Luckily you were here, otherwise I really wouldn't have been able to remember. Thank you!"

The girl with glasses pulled a bunch of snacks out of the desk drawer and put them on Tongsu's lap, then hugged her affectionately: "These are for you. They're my favorite chocolate and potato chips. They're so delicious. You should try them."

Xue Yu, who was standing next to her, said, "Alright, Yiwen, it's almost time for class. The new student can't carry that many things. You can wait until she's assigned a seat before putting them on her desk."

Yiwen, the girl with glasses, eagerly pulled Tongsu along, pleading, "Can you sit at the same table as me? We can discuss the problems together! I'm worst at Chinese, and not so good at math either. Can you teach me? I'm really good at humanities and English, so we can help each other."

Tong Su said, "When it comes to arranging seats, shouldn't we listen to the teacher?"

"No way! As long as the two classmates can help each other with their studies, and the other classmates are willing, we can switch seats as long as the class monitor agrees—Class monitor, can we sit at the same table?"

A classmate next to him complained, "Yi, the top student, is a really nice person, but she has this habit of giving her deskmate test papers as gifts. Not everyone in the class is a bad student, but who wants to spend most of their 24 hours a day drowning in a sea of ​​practice problems? New classmate, please have mercy, you've taken in a monster!"

Yiwen nodded repeatedly, clasped her hands together, and looked at Tongsu pitifully: "Please, I've never had a deskmate, and I'm so lonely. Will you sit with me?"

"I think you two are a good match. Two top students side by side, a perfect match. How about leaving us lazy bums alone?"

"Yes, yes!"

While the class was happily discussing, Teacher Yun had already arrived at the door and was looking inside. None of the students noticed her, so she walked to the podium and began to speak with a smile.

"I thought the new student wouldn't know everyone well since it's new, but it seems everyone gets along really well!"
