【开场】
（教室里，李华正在整理书包，张明走进来）
张明：嘿，李华！你听说了吗？王老师说今天要检查我们的英语口语作业。
李华：啊？真的吗？我还没准备好呢！
张明：别担心，我们一起复习一下吧。我记得上次你讲的那个关于旅行的故事挺有趣的。
李华：对呀，不过我现在有点紧张，怕说不好。
张明：没事的，放松点。我们可以先练习一下，就像平时聊天一样自然。
【第一幕：复习与准备】
（两人开始练习）
李华：Okay，let's start. I went to Beijing last summer vacation...
张明：Wait, wait! You said "went", but it should be "I have been to Beijing". Because you've already been there.
李华：Oh, right! Thanks for correcting me. So, I have been to Beijing last summer vacation...
张明：No, no, no! You can't say "last summer vacation" when using present perfect tense. Try saying "recently".
李华：Got it! So, I have been to Beijing recently.
张明：Perfect! Now continue with your story.
李华：Alright... I visited the Great Wall and took many pictures. Then, I ate some delicious food like Peking Duck.
张明：Great job! Your pronunciation is clear, and your grammar is almost correct. Just remember to use articles properly next time.
李华：Thanks for helping me out. I think I'm ready now.
【第二幕：课堂表演】
（铃声响起，同学们陆续回到座位上。王老师走进教室）
王老师：Good morning, everyone! Today, we will check your oral English homework. Who would like to volunteer first?
（李华举手）
王老师：Very good, Li Hua. Please come up here and share your story.
（李华走上讲台）
李华：Hello, everyone. I want to talk about my recent trip to Beijing. Recently, I have been to Beijing. I visited the Great Wall and took many pictures. Also, I tried some local foods such as Peking Duck. It was an amazing experience!
（同学们鼓掌）
王老师：Well done, Li Hua! Your pronunciation is excellent, and your grammar is accurate. Keep practicing, and you'll become even better.
李华：Thank you, Teacher Wang!
【结尾】
（下课后，李华和张明一起走出教室）
张明：See? I told you that you could do it. And look at how confident you were today!
李华：Yeah, thanks again for your help. I couldn't have done it without you.
张明：Anytime, buddy. That's what friends are for!
（两人笑着离开）
