It was a rainy morning two years ago. Shirley Huxham was cycling 1.(gentle) downhill. As she waved to a friend, her bike slid uncontrollably on the wet road, throwing her to the ground. “I’d never even thought of buying a helmet,” she says. For months she was partly paralysed (瘫痪) down her left side and still has 2.(healthy) problems today.

Some might think that Shirley was just unlucky. How 3.(danger) can it be to fall from a bicycle? In fact, each year on Britain’s roads more than 200 people are killed and at least 4,000 seriously injured on bicycles. But these numbers don’t tell the whole story: the majority of the 4.(die) and injured were not wearing helmets.

A study of bicycle accidents in the US found that helmets could 5.(reduction) the risk of serious head injury by 85 percent. Yet it is estimated that in Britain, no more than five percent of bicycle 6.(ride) wear helmets. Why don’t more cyclists wear 7. (they)?

People think that helmets look foolish, that they’re 8.(convenient), and that accidents only happen to other people.

One of the wrong ideas bicyclists have is that lower speeds can put them at 9.(little) risk than motorcyclists, who are legally obliged to wear helmets. In fact, according to a British report, a higher percentage of bicyclists than motorcyclists suffer head injuries. And their injuries can be just as severe.

Helmets, however, can make a big 10.(different). Shirley wasn’t just unlucky. If she had worn a helmet, she wouldn’t have spent months in hospital. Why take the risk?
