It is called ‘ The Covenant’, and was written by a famous American author called James Mitchener. It describes the history from the very first days, up to the present. It covers all aspects of the country, but focuses on the people of the country. For example, he looks at the political situation over the past fifty years, which was based on racial discrimination and had become known to the world as ‘apartheid’. 67. Do you often read the newspapers? ( 5 - 6 ) No, I never read a newspaper. I watch TV if I want to know what is happening in China and the world. Newspapers take to much time to read. For example, the news on TV is short and to the point, and that’s all I want to know. 67. Do you often read the newspapers? ( 7 - 8 ) No. Allow me to explain the reasons by shortly mentioning the following points: Firstly, I use the Internet these days if I want to know what’s happening in China and the world. For example, websites like CNN contain all the latest news on world events. Secondly, I like to read about stories in depth, and this I cannot find in newspapers.

Do colors have some symbolic meaning in China? ( 5 - 8 ) Yes, colors certainly have a lot of meaning in China. Please allow me to explain. Firstly, it is significant that the national flag of China has a red background. Red is symbolic, for example, of a vibrant life, which we believe are one of the dominant characteristics of the country and its people. It also signifies good luck, so a bride would wear some red on her wedding day. In addition, I think that yellow has a specific meaning to Chinese people. For example, we believe that it symbolizes the energy radiated by the sun, which in turn is the primary source of life. In addition, however, it also signifies the obscene, as apposed to blue in the most of the western cultures. For example, here a ‘blue movie’, would be called a ‘yellow movie’. Lastly, I think that white has a special meaning to us. To be more specific, in times of sadness and mourning, we use white to express our feelings, as apposed to black in most of the western cultures. h) SHOPPING 73. Do you like / enjoy shopping?

氟碳涂料的起源与发展? 最早的 氟碳涂料 诞生于1938年,原于杜邦公司的特氟隆涂层,即 聚四氟乙烯 、聚全氟丙烯等共聚合物。这类材料因其优异的耐热性和耐低温性以及自润滑性和化学稳定性能等,被称为“拒腐蚀、永不粘的特富龙”。但由于使用时需要高温固化,对颜料的分散性能差,当时只被用于不沾锅、医疗、航空等领域。   直到1965年美国成功开发出以 聚偏二氟乙烯 为基料的建筑用氟碳涂料,氟碳涂料才真正实现了商业化,氟碳涂料也开始在建筑领域展露出其良好的应用前景。目前全世界已有数以万计的建筑物在氟碳涂料的保护下熠熠生辉。但是由于此类涂料还是属于烘烤型涂料,温度大约在230℃,虽然比聚四氟乙烯要低,因其无法在现场使用,也制约了氟碳涂料的进一步推广。   直至1982年,日本开发出氟烯烃- 乙烯基醚 共聚物,从此开创了能常温下溶解于芳烃、脂类、酮类溶剂的常温固化氟树脂,不但克服了氟碳涂料不能常温固化的缺点,而且实现了可在施工工地现场涂装氟碳涂料的理想,并且大大拓展了氟碳涂料的应用领域。 文章来源: www.qirui7.com 原文地址: http://www.qirui7.com/news_show.asp?id=129 查看更多 0个回答 . 2人已关注
