阅读理解。 The legal limit for driving after drinking alcohol is 80 milligrams of alcohol in 100 milliliters of blood, when tested. But there is no sure way of telling how much you can drink before you reach this limit. It varies with each person depending on your weight, your sex, and what sort of drinks you've had. Some people might reach their limit after only about three standard drinks. In fact, your driving ability can be affected by just one or two drinks. Even if you're below the legal limit, you could still be taken to court if a police officer thinks your driving has been affected by alcohol. It takes hours for the body to get rid of the alcohol in one standard drink. So, if you have a heavy drinking session in the evening, you might find that your driving ability is still affected the next morning, or you could even find that you're still over the legal limit. In addition, if you've had a few drinks at lunchtime, another one or two drinks in the early evening may well put you over the legal limit till late in the night. In a test with professional drivers, the more alcoholic drinks they had had, the more certain they were that they could drive a test course through a set of moveable posts and the less able they were to do it! So the only way to be sure you're safe is not to drink at all. Alcohol is a major cause of road traffic accidents. One in three of the drivers killed in road accidents have levels of alcohol which are over the legal limit, and road accidents after drinking are the biggest cause of death among young men. More than half of the people stopped by the police to take a breath analyzer test have a blood alcohol concentration of more than twice the legal limit. It is important to remember that driving after you've been drinking doesn't just affect you. If you're involved in an accident, it affects a lot of other people as well, not least the person you might kill or injure. 1. Which of the following statements is NOT true? A.
