Question

阅读下面的短文，然后将划线部分的句子译成汉语或英语。

There are many different ideas about when and where the first toothbrush was invented.有人说它是11世纪在中国发明的。Others say the Romans invented it around the time of Caesar. Nobody knows the exact history of teeth cleaning.

Before the first toothbrushes, sharp (尖的) objects（物体）were used to clean teeth.

It’s believed that bribes in Africa and Australia invented the idea of cleaning their teeth. The modern toothbrush with bristles(毛) was invented in China much later in the 16th or 17th century. Toothbrushes moved to Europe in the mid 1600s .And then they became widely used in the area. Animal hair was the first type of bristle to be used.他们认为动物毛足够柔软。

Today, toothbrushes have nylon（尼龙） bristles and normally have a plastic handle. Animal hair was replaced by nylon in 1938. Electric(电动的)toothbrushes were invented and marketed in 1880 by “Dr. Scott”. But the electric toothbrush did not become popular until after World WarⅡ. When the cordless model was invented in 1960, its popularity increased a lot.
