参考答案:

墙面装修按施工方式和材料做法不同分为:勾缝类、抹灰类、贴面类、涂料类、裱糊类、铺钉类。

勾缝类:多用于砖墙的外表面,能保持砌体材料的本色及质地,因而称清水墙面。

抹灰类:属现场湿作业,其特点:材料来源广、施工操作简便、造价低廉。但饰面的耐久性低、易开裂、变色,且工效低。

贴面类:具有耐久性强、施工简便、工期短、质量高、装饰性好并易清洗等特点。目前应用较广泛。

铺钉类:通常有木质板墙面和金属薄板墙面。其中木质板墙面具有美观大方、安装方便等特点,但防潮、防火性能欠佳;金属薄板墙面具有重量轻、外形美观、经久耐用、强度高等特点。

裱糊类:具有色彩艳丽、图案雅致,且耐水、抗油污、易清洁等优点。如PVC塑料墙纸、纺织物面墙纸等,常用于室内墙装修。

Why do so many Americans distrust what they read in their newspapers? The American Society of Newspaper Editors is trying to answer this painful question. The organization is deep into a long self-analysis known as the journalism credibility project.

Sad to say, this project has turned out to be mostly low-level findings about factual errors and spelling and grammar mistakes, combined with lots of head-scratching puzzlement about what in the world those readers really want.

But the sources of distrust go way deeper. Most journalists learn to see the world through a set of standard patterns into which they plug each day’s events. In other words, there is a conventional story line in the newsroom culture that provides a backbone and a ready-made narrative structure for otherwise confusing news.

There exists a social and cultural disconnect between journalists and their readers, which helps explain why the "standard patterns" of the newsroom seem alien to many readers. In a recent survey, questionnaires were sent to reporters in five middle-size cities around the country, plus one large metropolitan area. Then residents in these communities were phoned at random and asked the same questions.

Replies show that compared with other Americans, journalists are more likely to live in upscale neighborhoods, have maids, own Mercedes, and trade stocks, and they’re less likely to go to church, do volunteer work, or put down roots in a community.

Reporters tend to be part of a broadly defined social and cultural elite, so their work tends to reflect the conventional values of this elite. The surprising distrust of the news media isn’t rooted in inaccuracy or poor reportorial skills but in the daily clash of world views between reporters and their readers.

This is an explosive situation for any industry, particularly a declining one. Here is a troubled business that keeps hiring employees whose attitudes vastly annoy the customers. Then it sponsors lots of symposiums and a credibility project dedicated to wondering why customers are annoyed and fleeing in large numbers. But it never seems to get around to noticing the cultural and class biases that so many former buyers are complaining about. If it did, it would open up its diversity program, now focused narrowly on race and gender, and look for reporters who differ broadly by outlook, values, education, and class.
