There is extraordinary exposure in the United States to the risks of injury and death from motor vehicle accidents. More than 80 percent of all households own passenger cars or light trucks and each of these is driven an average of more than 11,000 miles each year. Almost one-half of fatally injured drivers have a blood alcohol concentration (BAC) of 0.1 percent or higher. For the average adult, over five ounces of 80 proof spirits would have to be consumed over a short period of time to attain these levels. One third of drivers who have been drinking, but fewer than 4 percent of all drivers, demonstrate these levels. Although less than 1 percent of drives with BACs of 0.1 percent or more are involved in fatal crashed, the probability of their involvements is 27 times higher than for those without alcohol in their blood. There are a number of different approaches to reducing injuries in which drinking plays a role. Based on the observation that excessive consumption correlates with the total alcohol consumption of the country"s population, it has been suggested that higher taxes on alcohol would reduce both. While the heaviest drinkers would be taxed the most, anyone who drinks at all would be punished by this approach. To make drinking and driving a criminal offense is an approach directed only at drinking drivers. In some states, the law empowers police to request breath tests of drivers committing any traffic offense and higher BAC can be basis for arrest. The National Highway Traffic Safety Administration estimates, however, that even with increased arrests, there are about 700 violations for every arrest. At this level there is little evidence that laws are effective ways to reduce drunk driving. In Britain, motor vehicle accidents fell 25 percent immediately following implementation of he Road Safety Act in 1967. As Britishers increasingly recognized that they could drink and not be stopped, the effectiveness declined, although in the following three years the death-rate seldom reached that observed in the seven years prior to the Act. Whether penalties for driving with a high BAC or excessive taxation on consumption of alcoholic drink will deter the excessive drinker responsible for most accidents is unclear. One thing is clear, however, unless we deal with automobile and highway safety and reduce accidents in which alcoholic drinking plays a role, many will continue to die. The author is primarily concerned with______

The importance and focus of the interview in the work of the print and broadcast journalist is reflected in several books that have been written on the topic. Most of these books, as well as several chapters, mainly in, but not limited to, journalism and broadcasting handbooks and reporting texts, stress the "flow to" aspects of journalistic interviewing rather than the conceptual aspects of the interview, its context, and implications. Much of the "how to" material is based on personal experiences and general impressions. As we know, in journalism as in other fields, much can be learned from the systematic study of professional practice. Such study brings together evidence from which broad generalized principles can be developed. There is, as has been suggested, a growing body of research literature in journalism and broadcasting, but very little significant attention has been devoted to the study of the interview itself. On the other hand, many general texts as well as numerous research articles on interviewing in fields other than journalism have been written. Many of these books and articles present the theoretical and empirical aspects of the interview as well as the training of the interviewers. Unhappily, this plentiful general literature about interviewing pays little attention to the journalistic interview, which seems to be surprising for two reasons. First, it seems likely that most people in modem Western societies are more familiar, at least in a positive manner, with journalistic interviewing than any other form of interviewing. Most of us are probably somewhat familiar with the clinical interview, such as that conducted by physicians and psychologists. In these situations the professional person or interviewer is interested in getting information necessary for the diagnosis and treatment of the person seeking help. Another familiar situation is the job interview. However, very few of us have actually been interviewed personally by the mass media, particularly by television. And yet, we have a vivid acquaintance with the journalistic interview by virtue of our roles as readers, listeners, and viewers. Even so, the understanding of the journalistic interview, especially television interviews, requires thoughtful analyses and even study, as this book indicates. Westerners are familiar with the journalistic interview,______
在考生文件夹下，“samp1．accdb”数据库文件中已建立两个表对象(名为“职工表”和“部门表”)。试按以下要求，顺序完成表的各种操作： (1)设置表对象“职工表”的聘用时间字段默认值为系统日期。 (2)设置表对象“职工表”的性别字段有效性规则为：男或女；同时设置相应有效性文本为“请输入男或女”。 (3)将表对象“职工表”中编号为“000019”的员工的照片字段值设置为考生文件夹下的图像文件“000019．bmp”数据。 (4)删除职工表中姓名字段含有“江”字的所有员工记录。 (5)将表对象“职工表”导出到考生文件夹下的“samp．accdb”空数据库文件中，要求只导出表结构定义，导出的表命名为“职工表bk”。 (6)建立当前数据库表对象“职工表”和“部门表”的表间关系，并实施参照完整性。

考生文件夹下存在一个数据库文件“samp3．accdb”，里面已经设计了表对象“tEmp”、查询对象“qEmp”、窗体对象“fEmp”和宏对象“mEmp”。同时，给出窗体对象“fEmp”上一个按钮的单击事件代码，试按以下功能要求补充设计： 功能： (1)将窗体“fEmp”上文本框“tSS”更改为组合框类型，保持控件名称不变。设置其相关属性实现下拉列表形式输入性别“男”和“女”。 (2)将窗体对象“fEmp”上文本框“tPa”换为复选框类型控件，保持控件名称不变，然后设置控件来源属性以输出“党员否”字段值。 (3)修正查询对象“qEmp”设计，增加退休人员(年龄>=55)的条件。 (4)单击“刷新”按钮(名为“bt1”)，在事件过程中补充语句，动态设置窗体记录源为查询对象“qEmp”，实现窗体数据按性别条件动态显示退休职工的信息；单击“退出”按钮(名为“bt2”)，调用设计好的宏“mEmp”来关闭窗体。 注意：不允许修改数据库中的表对象“tEmp”和宏对象“mEmp”；不允许修改查询对象“qEmp”中未涉及的属性和内容；不允许修改窗体对象“fEmp”中未涉及的控件和属性。 程序代码只允许在“*****Add*****”与“*****Add*****”之间的空行内补充一行语句、完成设计，不允许增删和修改其他位置已存在的语句。
