Every day, it is easy to see advertisements in English all around us. Look at your own bags and clothes of your classmates. How many different advertisements can you see which use English words? Often, bags and clothes show the name of company that made them. This is a popular form. A special picture or symbol (标志) called a logo is sometimes used. Logos appear on many different products. They are popular because when you see a logo, it helps you to remember that product or company. It is common to see advertisements on TV and hear them on the radio. Most advertisements are very short. Sometimes the advertisers use a short sentence and it is easy for people to say. Nike, for example, has a simple English sentence which is used all around the world: “Just do it.” Advertisements often use funny situations as well. It is simple to remember it. All advertisements are designed to make people buy a product. An advertisement for a soft drink, for example, might show a group of young people who are having fun. The young people are all drinking the soft drink. Advertisements are saying to you, “Why don’t you buy this drink and be like these people? You can be young and modern.” You might think that advertisements are not for you, but the next time you buy a soft drink, ask yourself this question: Why am I buying this particular product?

L省D市一幢商住楼工程项目,建设单位A与施工单位B以及监理单位C分别签订了施工承包合同与施工阶段委托监理合同。该工程项目的主体工程是钢筋混凝土框架式结构,设计要求混凝土抗压强度达到C20。在主体工程施工到第三层时,钢筋混凝土柱浇筑完毕拆模之后,监理工程师发现,第三层全部80根钢筋混凝土柱的外观质量很差,不仅蜂窝麻面十分严重,而且表面的混凝土质地酥松,用锤轻敲便有混凝土碎块脱落。经检查确认,施工单位提交的从9根柱施工现场取样的混凝土强度试验结果表明,混凝土抗压强度值都达到或者超过了设计要求值,其中最大值达到C30的水平,监理工程师对于施工单位提交的试验报告结果十分怀疑。
