在英語口語中，關(guān)于上課的表達(dá)方式如下：

1. 開始上課：

"Let's start class."

"It's time for class."

"Good morning, class."

"Good afternoon, everyone."

2. 學(xué)生進(jìn)入教室：

"I have to go to class."

"I'm going to class."

3. 學(xué)生起立和坐下：

"Stand up, please."

"Sit down, please."

4. 詢問出勤情況：

"Who is on duty today？"

"Is everyone here？"

"Is anyone absent？"

5. 結(jié)束上課：

"That's all for today. Thank you for your attention."

"Goodbye, see you tomorrow."

這些表達(dá)可以幫助你在課堂上進(jìn)行基本的交流。
