根据材料请回答Stricter Traffic Law Can Prevent AccidentsFrom the point of view of health we are living in a marvelous age.We are immunized from birth against many of the most dangerous diseases.A large number of once fatal ill- nesses can now be cured by modern drugs and surgery.It is almost certain that one day remedies will be found for the most stubborn remaining diseases.The life expectancy(平均寿命) has increased enormously.-But though the possibility of living a long life is greater than ever before, every day we witness the incredible slaughter of people on the roads.Man versus(对顶，对抗)the car (人车对抗) ！ It is a never-ending battle which man is los- ing.Thousands of people in the .world are killed each year and we are quietly sitting back and letting it happen.
It has been said that when a man is sitting behind a steering wheel, his car becomes the extension of his personality.There is no doubt that the.car often brings out a man's worst qualities.People who are normally quiet and pleasant may become unrecognizable when they are behind a steering-wheel.They are furious, ill-mannered and aggressive.All their hidden frustrations, disappointments and jealousies seem to be brought to the surface by the act of driving.
The surprising thing is that society smiles so benignly(仁慈地，良性地)on, the motor-ist and seems to condone(宽容)his behavior.Everything is done for his convenience.Cit-ies are allowed to become almost uninhabitable because of.heavy traffic; towns are made ugly by huge car parks; the countryside is destroyed by road networks; and the mass an-nual slaughter becomes, nothing more than a statistic, to be soon forgotten.
It is high time to reduce this senseless waste of human life.With regard to driving, the laws of some countries are notoriously lax.A code(法规)which was universally accept-ed could only have a dramatically beneficial effect on the accident rate.Here are a few ex-amples of some of the things that might be done.The driving test should be made far more difficult than it is； all the drivers should take a test every three years or so; the age at which young people are allowed to drive should be raised to at least 21; all vehicles should be put through stringent(严格的)annual tests for safety.Present drinking and driving laws should be much stricter.Governments should lay down safety specifications for manu-facturers, as has been done in the USA.All advertising stressing power and performance should be banned.These measures may sound inordinately harsh.But surely nothing should be considered as too severe if it results in reducing the annual toll of human life.
After all, the world is for human beings, not for cars.The main idea of this passage is________. A．Traffic accidents are mainly caused by" motorists
B．Thousands of people the world over are killed each year
C．The laws of some countries about driving are too lax
D．Only stricter traffic laws can prevent accidents
