Driving a car is not just handling controls and judging speed and distance. It requires you to predict what other road users will do and get ready to react to something unexpected. When alcohol is consumed, it enters your bloodstream and acts as a depressant (抑制药), damaging eyesight, judgment and co-ordination(协调)，slowing down reaction time and greatly increasing the risk of accidents. Even below the drink driving limit, driving will be affected.
Alcohol may take a few minutes to be absorbed into the bloodstream and start action on the brain. Absorption rate is increased when drinking on an empty stomach or when consuming drinks mixed with fruit juice. To get rid of alcohol from the body is a very slow process and it is not possible to speed it up with any measures like taking a shower or having a cup of tea or coffee.
The present Road Traffic Ordinance states clearly that the limit of alcohol concentration is:
50 milligrams of alcohol per 100ml of blood; or
22 micrograms of alcohol per 100ml of breath; or
67 milligrams of alcohol per 100ml of urine(尿液).
Drivers who cause traffic accidents, or who commit a moving traffic offence or are being suspected of drink driving will be tested.
Any driver found drinking beyond the limit will be charged. The driver declared guilty may be fined a maximum of HK $25,000 and be sentenced to up to 3 years in prison and punished for 10 driving-offence points; or temporarily banned from driving.
The same punishment applies to failing to provide specimens(样本)for breath, blood or urine tests without good excuse.
Drink driving is a criminal offence. Be a responsible driver, think before you drink. For the safety of yourself and other road users, never drive after consuming alcohol.

题目分析：本文是一篇社会文化类的说明文。文章主要介绍了驾车不光控制车速和车距，还要求司机能预测其他司机的行为，并对各种突发事件做出及时的反应，然而酒后驾车影响人的视力，判断力和协调力。进而使人的反应速度降低，增加了发生车祸事故的可能性。本文主要介绍了酒后驾车产生的影响及危险性，以及酒后驾车的一些相关规定。
小题1:主旨大意题根据文章第一段的主要内容，酒精进入人体的血液，影响人的视力，判断力和协调力。进而使人的反应速度降低，增加了发生车祸事故的可能性。由此可知，文章第一段的主要内容就是酒后驾车的影响。所以答案为C
小题2:指代题中的指示指代题。本题考查文章中指示代词所指代的内容，属于较易难度的题。根据文章内容的理解，使酒精排出人体是一个非常缓慢的过程，不管采取任何措施都不可能加剧这个过程的速度。由此可知，“it”指代的就是这个酒精排出人体的过程。所以答案为D。
小题3:细节理解题。选项A来自于文章中的Even below the drink driving link, driving well be affected.由此可知，A选项错误。C选项来自于文章中的it is not possible to speed it up with any measures like taking a shower or having a cup of tea or coffee.由此可知，C选项错误。D选项来自于文章中的50 milligrams of alcohol per 100ml of blood由此可知，D选项错误。B选项来自于文章中的Absorption rate is increased when drinking on an empty stomach or when consuming drinks mixed with fruit juice.由此可知，B选项正确。
小题4:细节理解题：本题考查对文章中的相关细节的寻找和把握，属于较易难度的题。根据文章内容，题目来自于文章中的who commit a moving traffic offence or are being suspected of drink driving will be tested.由此可知，疑似酒后驾车的司机应该接受检查。所以答案为A。
