答案与题解：
1. C 选项A、B、D所述内容都可在短文的第一、第二段中找到。第二段最后一个句子告诉我们，传感器装在司机和乘客的座椅里，而不是在点火系统里，所以选择C.
2. B 短文第三段告诉我们，沃尔沃公司也发明了一种相类似的酒精检测装置，安装在保险带上。所以B是正确选择。
3. A 第四段描写了安装在概念车仪表板上的照相机的功能。相机跟踪司机的眼睛的活动从而监测司机是否保持清醒状态，如果发现司机需要停车休息，便用英语或日语发出警告。所以除A以外，其他选择都不正确。
4. D 短文第五段说，这种监测技术仍然在发展之中，使用不同的监测系统应能改进这项技术的整体有效性，所以A和C都不是正确选择。该段的最后一句说，日产公司并不准备将这种监测系统推向市场，但它的目标是使用这种技术到2015年将日产车的事故率年减少到 1995年的一半。所以B也不是正确选择，只有D表达了Doi的意思。
5. B 选项A、C、D在短文第六段都能找到，但是却找不到选项B所表达的意思。
