题文
阅读理解。 A device that stops drivers from falling asleep at the wheel is about to undergo testing at Departmentof Transport laboratories and could go on sale within 12 months. The system, called driver alert, aims to
reduce deadly road accidents by 20%-40% that are caused by tiredness. Airline pilots can also use it to
reduce the 30% of all pilot-error accidents that are related to fatigue.
Driver alert is based on a computerized wristband. The device, worn by drivers or pilots gives out a
sound about every four minutes during a car journey. After each sound the driver must respond by squeezing
the steering wheel (方向盘). A sensor in the wristband detects this pressing action and measures the time
between the sound and the driver's response.
Tiredness is directly related to a driver's response time. Usually, a watchful driver would take about 400
milliseconds to respond, but once that falls to more than 500 milliseconds, it suggests that the driver is getting
sleepy.
In such cases the device gives out more regular and louder sounds, showing that the driver should open a
window or stop for a rest. If the driver's response continues to slow down, the sounds become more frequent
until a nonstop alarm warms that the driver must stop as soon as possible.
The device has been delivered to the department's laboratories for testing. If these tests, scheduled for six
months' time, are successful, the markers will bring the product to market within about a year. 1. According to the text, Driver alert ______. A. aims to reduce tiredness-related accidents
B. has gone through testing at laboratories
C. aims to prevent drivers from sleeping
D. has been on sale for 12 months 2. How should a driver respond to the sounds from Driver alert? A. By sounding a warning
B. By touching the wristband
C. By checking the driving time
D. By pressing the steering wheel 3. We can learn from the text that the driver needs to stop for a break when his response time is ______. A. about 400 milliseconds
B. below 500 milliseconds
C. over 500 milliseconds
D. about 400 minutes 4. When the driver gets sleepy while driving, Driver alert ______. A. moves more regularly

考点
据考高分专家说，试题“阅读理解。 A de.....”主要考查你对 [日常生活类阅读 ]考点的理解。日常生活类阅读
日常生活类阅读的概念：
日常生活这一话题主要涉及人们衣食住行等方面的活动。这一话题的选材主要针对人们日常的工作，生活以及学习情况。做这一类题时，最主要的是要把握好人物的活动内容，时间和地点。
日常生活类阅读题答题技巧：
【题型说明】
该类文章内容涉及到人们的言谈举止、生活习惯、饮食起居、服饰仪表、恋爱婚姻、消遣娱乐、节日起源、家庭生活等。文章篇幅短小，追根溯源，探索各项风俗的历史渊源，内容有趣。命题也以送分题为主，如事实细节题、语义转换题、词义猜测题和简单推理判断题等。虽然这类文章读起来感觉轻松，试题做起来比较顺手，但绝不能掉以轻心。因为稍不留神，就会丢分。
【备考提醒】
为了保证较高准确率，建议同学们做好以下几点：
1、保持正常的考试心态。笔者在教学中发现，越是容易的试题，同学们越是容易失分。为什么呢？因为在这种情况下，同学们极易产生麻痹思想，认为题目好做，就不引起高度重视，于是思维不发散、不周密。而命题人就是利用同学们的这一弱点，设计陷阱题。所以，无论试题难易与否，我们都要保持正常的考试心态。试题容易，不欣喜；试题难，不悲观。
2、根据前面讲到的方法，认认真真、细细心心做好事实细节题。
3、做好语义转换题。这类题是根据英语中一词多义和某些词语在文中能表达一定的修辞意义的原则而设计的。要求同学们解释某生词的含义，确定多义词或短语在文中的意思，确认文中的某个代词所指代的对象，或者对英语中特有的表达、格言、谚语进行解释。这种题要求同学们一定要根据上下文猜测词义或理解句子，切不可望文生义。
4、做好简单推理判断题。简单推理判断题要以表面文字为前提，以具体事实为依据进行推理，做出判断。这种推理方式比较直接，只要弄清事实，即可结合常识推断出合理的结论。
