| Going to sleep may seem pretty boring compared with all the fun things you do while you are awake. But there's a lot going on in your mind and body while you are sleeping. Sleep, in fact, is as important to your survival as eating and drinking. Sleep improves your mood, makes you a better athlete, and helps you remember and understand what you learned during the day. During sleep, your temperature drops. Your heart beats slowly. A chemical that controls growth, which is called a hormone (荷尔蒙), moves into your bloodstream. Scientists think that sleep brings back energy and improves your immune (免疫) system. We know what happens while we're asleep because scientists study volunteers who sleep in laboratories. The sleepers are connected with machines that measure brain waves, eye movements and muscle activities. Sleep is like a school day: it's divided into different stages (阶段). When you are awake, your brain waves fire rapidly (迅速地). As you begin to relax and drift into the first stage of sleep, your brain produces slower-moving waves and you lose awareness (意识) of your surroundings. As you fall into deeper sleep, your body repairs itself from the normal wear and tear of daily life. Then, as you begin to drift back up to a lighter sleep, your mind becomes more alert (警觉的), and your dreams begin. You are in REM sleep. REM is the name for the rapid eye movement that happens while you are dreaming. During REM sleep, your eyes move back and forth behind your lids, as though you were watching a movie. During other stages, you might move in bed, but during REM sleep you're not making any movement. That's probably because if you could move, your body would act out your dreams. As you get close to morning, you spend more time in REM than in deep sleep, so you dream more. Researchers know that during REM sleep the part of the brain that deals with learning and thinking is very active. Getting too little sleep can affect your personality. Experts recommend that children get at least nine hours'sleep a night. |

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, judgement
and coordination(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
drivingoffence 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.
