[单项选择]

In our lifetime, we should suffer from a lot of hardship, setback and misery. Perhaps no body could free from these unhappy things. Accidents and illnesses are unhappy things to talk about, but no one can expect to live a lifetime without having some kind of accident or becoming ill. Some accidents and illnesses are serious and may result in long periods of invalidism.
The newspapers contain spectacular accounts of accidents in the street and highways and public places, but nearly as many accidents occur around the home. Somebody trips on a rug. Somebody falls off a stepladder. Somebody is careless in cooking dinner, and is burned. Accidents incurred in the playing of sports and swimming also accounts for a large number of injuries, big and little. Despite constant campaigns to reduce the number of accidents, there are still approximately 100,000 accidental deaths and nearly 9,000,000 non-fatal injuries in the United States each year.
