When I was twelve years old, my family were the first black people to move into an all white part of Grand Rapids, Michigan. Many of our new neighbors weren’t very welcoming. Some of them said angrily that we should return to where we came from. The children sometimes threw stones at me .

Most of my teachers simply took no notice of me, but not Dorothy Bean, my history teacher. Miss Bean was angry at how badly I was being treated, but she didn’t say this to me. Miss Bean showed her respect for me by teaching me just like anyone else. Instead of being unnoticed, I was given a chance to show that I was clever. Miss Bean was the first teacher who ever made me think for myself. She always wanted to know what I thought about different questions. She expected me to have my own idea. Miss Bean was teaching me that thinking for oneself was the real key to education.

One day, when I was not paying attention in class, Miss Bean suddenly threw an eraser(黑板擦) at me. The eraser hit me right on the hand and sent my pencil flying. The whole class were very surprised at first, then started laughing. This event became famous in the school and, because it happened to me, the students wanted to get to know me. So that’s the story of how Dorothy Bean made me her target(靶子). However, what I want to do is express my thanks to her.

某承包商浇筑基础底板混凝土时，现场搅拌棚拌出的混凝土配合比没有试配报告，现场计量装置未经监理工程师检查核定。同时，在二层框架柱纵向钢筋使用时因材料堆放错误导致直径小于设计要求直径2mm。在三层施工时由建设方购买到现场的100t钢筋，虽然有正式的出厂合格证，但现场抽检材质化验不合格。在四层现浇混凝土上午绑扎钢筋完毕后，下午上班未经检查验收，就浇筑混凝土。在八层梁柱施工时，由于构件截面尺寸小，绑扎钢筋有困难，于是钢筋工决定通过等强代换原则，改变梁柱节点的梁的钢筋直径与数量。十层混凝土施工时预留试块经检验达不到设计要求的C30强度等级。层盖顶上的钢结构电焊时，经检查发现部分电焊工没有持证就上岗。
