阅读下面短文并回答问题（请注意问题后的词数要求）。

When your toothbrush is at the end of its days, don’t just throw it away, as a survey has revealed many other uses for an old toothbrush.

The survey was carried out by the Dental Health Foundation to promote National Smile Month and more than 1, 000 people participated in the survey. It found that more than four in every five people re-use their toothbrush for another purpose.

Four in ten people use an old toothbrush to brush bathroom tiles (瓷砖), and almost a third use it to clean kitchen appliances. More than a quarter of those questioned use old toothbrushes to clean jewellery, and roughly one in every five use them for shining shoes. Some other uses for toothbrushes include cleaning bikes, computer keyboards, toilet seats, fish tanks and finger nails.

The survey also found that the age of the owner can determine what happens to a toothbrush after it is not suitable to be used to brush teeth any more. People over 75 are three times more likely to re-use their toothbrush for a different purpose than those between the ages of 16 and 34 and twice more likely than those between 35 and 44.

Additionally,           to reuse their toothbrush for chores (日常琐事) and other uses than their male counterparts. Some women admitted to using their toothbrush to apply hair dye (染料)while some men said they used an old toothbrush to clean their dog’s teeth.

Chief Executive of the British Dental Health Foundation, Dr Nigel Carter, said, “We all should get through around four toothbrushes every year if we are to keep our oral health in great condition. Generally people don’t change their toothbrushes often enough, but there are still plenty of toothbrushes

lying around the house. Our survey has shown that people have realized that a toothbrush is of great value and has a role to play beyond its normal use.”
