施工现场不同层次高度同时进行交叉作业时，有什么安全要求？

When I was about 13, I had an enemy, a girl who liked to point out my shortcomings (缺点). Sometimes she said I was lazy. Sometimes she said I wasn’t a good student.   小题1: . I tried to put up with (忍受) her as long as I could. At last, I became very angry.   小题2: .
My father listened to me quietly, and then he asked, “Are the things she said true or not? Go and make a list of everything she said and mark the points that are true. Pay no attention to the other things she said.”
I returned to my room and I did as my father told me. To my surprise, I found that about half the things were true.   小题3: . He refused to take the list. “That’s just for you,” he said. “When something said about you is true, you’ll find it will be helpful to you. Listen to them all, but hear the truth and do what you think is right.”
Many years have passed.   小题4: . In our life we often meet with some trouble and we often go to someone and ask for advice. For some advice you will treasure (珍惜) all your life!

A. I brought the list back to my father B. The situation often appears in my mind C. My mum didn’t like me D. I ran to my father E. Sometimes she said I talked too much
