他对我说谎了 He lied to me

Good morning, everyone! Let me introduce myself first. My name is Li Ming, a student from Class One, Grade Nine, Hongxing Middle School. Yesterday afternoon, the student on duty said he had to see the doctor. I offered to do the cleaning for him. Later I found him playing basketball on the playground. I was quite unhappy. He was tell the lie. I would do the duty for him if he students, we should always tell the truth even if others might not agree with us. When others tell lies, we’d better make them understand that honesty is the best ’s all. Thank you.

大家早上好！让我先自我介绍。我的名字是李明，红星中学九年级一班的学生。昨天下午，值班的'同学说，他要去看医生。我愿意帮他做清洁。后来我发现他在操场上打篮球。我很不高兴。他跟我说谎了。但是如果他叫我帮忙我也会愿意帮助他。作为学生，我们应该始终讲真话，即使其他人可能不同意我们的意见。当别人说假话，我们最好让他们明白，诚实是最好的政策。这就是全部。谢谢。
