There are many different ideas about when and where the first toothbrush was invented. Some say it was invented in China around the 11th century. Others say the Romans(罗马人) invented it around the time of Caesar. Nobody knows the exact history of teeth cleaning.
Before the first toothbrushes, sharp(尖的) objects were used to clean teeth.
It’s believed that tribes(部落) in Africa and Australia invented the idea of cleaning their teeth. The modem toothbrush with bristles(毛) was invented in China much later in the 16th or 17th century. Toothbrushes moved to Europe in the mid 1600’s and then became widely used in the area. Animal hair was the first type of bristle to be used.
Today, toothbrushes have nylon(尼龙) bristles and normally have a plastic handle. Animal hair was replaced by nylon in 1938. Electric toothbrushes were invented and marketed in 1880 by “Dr Scott”. The popularity of the electric toothbrush did not take off until after World War Ⅱ. When the cordless(无线的) model was invented in 1960, its popularity increased a lot.

“Who needs a shopping mall if you have Taobao?” says Wang Lin, 28, a writer in Beijing.
Taobao, China’s largest online shopping site has become an important part of Wang Lin’s life. She spends lots of money on Taobao.
A growing number of Chinese Internet users like Wang have found the joys(乐趣) of online shopping. Most online shoppers are students or young workers. More women shop on line than men. Clothing and home-use products are the most popular on line.
It was reported that more than 250 billion yuan was spent on online shopping last year, 80% through Taobao.
Taobao means “looking for treasure(财富)” in Chinese. People can find almost everything they need on Taobao, from clothes to books, from candies to DVD players.
You may question the security of online shopping. Wang Lin said, “It’s very safe and convenient. Unless you receive the products from the sellers and are satisfied(满意的) with them, the shop owner will not get the money.” You can also get you money back if you want to return the products.

Internet is always educational. Many people think children should be allowed to surf the Internet as they wish. In this way, they can look through different subjects on different kinds of websites according to their own interest. But in my opinion, children should always be watched while surfing the internet.
Many websites have information and pictures that children should not see. There are many things that children don’t understand. All of these may have some bad influence on children’s development. Also, it is dangerous to let children use chat rooms by themselves. Many parents tell their children not to talk to strangers on the street, so they should be careful of whom their children talk to on the Internet, too. What’s more, sitting in the front of a computer for a long time isn’t good for children’s eyes, so parents should monitor(监视) the time that childen spend on the Internet.
In a word, children should be kept away anything that could be bad for them. I believe that it is necessary for parents to watch their children when they use Internet.
