问题     The north Australian city of Darwin was devastated by a strong cyclone(龙卷风)on Christmas Day. The death and destruction were due almost as much to human factors as to the violence of the wind.
    People in Darwin had become so accustomed to cyclone warnings that few of them paid attention to the radio warnings of Cyclone Tracy approach, which began early on Christmas Eve. Many people, in fact, died in their cars as they tried to drive home through the cyclone from Christmas parties or social calls.
    Since Townsville was devastated by a cyclone in December 1971 , the weather authorities have regularly issued alarms of every dangerous cyclone. But because few of the cyclones ever hit the coastal towns, people there had come to ignore the warnings.
    Darwin’s last alert was broadcast only two weeks before Cyclone Tracy. On that occasion the storm changed direction and headed off harmlessly down the coast.
    Apart from those people killed in their cars, nearly all the other victims died in the damage of their homes which, despite the fact that Darwin lies in the recognized cyclone belt, had not been built to withstand cyclonic winds. Although building standards in other states of Australia were made much stricter after the tragedy at Townsville, the Darwin authorities never followed the new regulations. Consequently most of suburban Darwin was built of light wood and iron raised off the ground on piles to give coolness in the tropical climate. And the sides of the houses were simply nailed to the roof instead of being firmly attached with what Australian builders call " cyclone bolts . As a result, many people were killed by flying sheets of iron from the roofs.
The passage is meant to illustrate that______.
选项 A、cyclones hit the coastal towns of Australia quite often
B、it is essential to establish an adequate cyclone warning system
C、the tragedy of Darwin was to a great extent due to the negligence of the cyclone warning
D、much can be done to avoid the attack of cyclones
答案C
