It is a mystery that has puzzled doctors for decades. But experts believe they have now finally solved the tricky question of why winter is notoriously known as the flu season.
According to a new research, the influenza virus coats itself in a protective fatty shield that is tough enough to resist cold temperatures. The butter-like material only melts when it hits the respiratory tract（呼吸道）, leaving the virus free to infect cells-- a process scientists say is like an M&M melting in the mouth.
However, in warmer outdoor temperatures, the protective coating melts before it reaches a person or an animal, killing the bacteria before they can infect someone. Joshua Zimmerberg, from the National Institute of Child Health and Human Development (NICHD), in the US, which led the study, said: “Like an M&M in your mouth, the protective covering melts when it enters the respiratory tract. It's only in this liquid period that the virus is able to enter a cell to infect it.”
In the past, scientists worked on theories that flu is more common in winter because people spend more time inside or the radiation from the sun in summer kills off germs. But no research successfully explained the spread of the disease.
Researchers have already claimed that the report, which is published in the journal Nature Chemical Biology, could lead to new ways to prevent and treat flu. “Now that we understand how the flu virus protects itself so that it can spread from person to person, we can work on ways to prevent it.”
Influenza and other respiratory viruses are spread in small drops broadcast by coughing, sneezing and talking and which can also settle onto surfaces, to be picked up on fingertips.

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.

1.The first paragraph is mainly about______.

A. the introduction of driving skills

B. the damage of drinking to your body

C. the effect of drinking on driving

D. the process of alcohol being absorbed

2.The underlined Word“ it” in the second paragraph refers to “______ ”.

A. alcohol B. absorption    C. blood    D. process

3.Which of the following is TRUE according to the passage?

A. Drinking below the drink driving limit has no effect on driving.

B. Alcohol is taken in more quickly when drunk with fruit juice.

C. Having a cup of tea helps to get rid of alcohol from the body.

D. 50 milligrams of alcohol per 100ml of breath is below the drink driving limit.

4.A driver suspected of drink driving ________.

A. should provide specimens for testing

B. will be forbidden to drive for 3 years

C. will be punished for 10 driving-offence points

D. should pay a maximum fine of HK $ 25,000
