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.”

Global warming is when the earth heats up，the temperature rises.It happens when greenhouse gases—carbon dioxide，water vapor，nitrous oxide(二氧化氮)，and methane(沼气) trap heat and light from the sun in the earth’s atmosphere，which increases the temperature.This is like when heat is trapped in a car.On a very hot day，the car gets hotter when it is out in the parking lot.This is because the heat and light from the sun can get into the car，by going through the windows，but it can’t get back out.Once the light is inside the car，it is trapped and the heat builds up，just like it does in the earth’s atmosphere.This is what the greenhouse effect does to the earth.The heat and light can get through the atmosphere，but it can’t get out.As a result，the temperature rises.

Sometimes the temperature can change in a way that helps us.The greenhouse effect makes the earth appropriate for people to live on.Without it，the earth would be freezing，or on the other hand it would be burning hot.We would not get the sun’s heat and light to make the night somewhat warm.During the day，especially during the summer，it would be burning because the sun would be up with no atmosphere to filter(过滤) it，so people，plants，and animals would be exposed to all the light and heat.

Although the greenhouse effect makes the earth able to have people living on it，if there gets to be too many gases，the earth can get unusually warmer，and many plants，animals，and people will die.They would die because there would be less food (plants like corn，wheat，and other vegetables and fruits)．This would happen because the plants would not be able to take in the heat.This would cause us to have less food to eat，but it would also limit the food that animals have.Gradually，people，plants，and animals would all die of hunger.

People are doing many things to try to stop global warming.One thing people are doing is carpooling.Carpooling is driving with someone to a place that you are both going to.This minimizes the amount of greenhouse gases put into the air by a car.

Another thing that people are doing is being more careful about leaving things turned on like the television，computer，and the lights.A lot of people are taking time away from the television，and instead，they are spending more time outdoors.This helps our planet out a lot.Now，more people are even riding buses，walking to school，and riding their bikes to lower the amount of greenhouse gases in the air.

Planting trees and recycling also help.If you recycle，less trash goes to the dump，and less trash gets burned.As a result，there are fewer greenhouse gases in our atmosphere.Although adults do many things to help stop global warming，kids can do just as much.

For many years, women could only be seen on the seat behind the men operating the two－wheeled motorcycle. Now more and more women are taking the front seat. More than twenty million people in the United States ride motorcycles.

Since 1998 the number of female bikers has risen sharply. Lady Sport Riders began in 1999 in Washington. The women formed the organization to share their love of motorcycle riding. But later it wanted to be more than just an organization for women togather and ride motorcycles, so it started to organize events that help national health organizations and women's shelters. It also permits women to share a strong sisterhood, and gives financial awards to poor students. Like other motorcycle clubs, the members of Lady Sport Riders also help their community. 

Different from male riders, female riders ride for more than fun. This sport gives women a sense of freedom and control. Female riders have helped change motorcycle culture. More than five years ago manufacturers began making equipment especially for women. Some bikes now have smaller, softer seats and controls that are easier to reach. Modern clothes for riding now look good and still provide protection. In the past, women rode motorcycles that travelled at a moderate speed. Now theirs are as powerful as the ones men ride. Safety is very important when riding because the risk of injury is high. So the women wear protective clothing and equipment at all times, especially for the head.

Lady Sport Riders believes women have earned their place in the sport of motorcycle riding. When speaking of male motorcyclists, the members of the club say, “They Made the Game. We Came to Play！”
