VOA慢速英语2012.01.16 牙齿, 英语, painful, example, release

Rebecca949

Bad teeth can be painful -- and worse. They can even be deadly. Infections of the gums and teeth can release bacteria into the blood system.
牙齿坏了会很痛，甚至更糟，可能会致命。被感染的牙龈和牙齿向血液系统释放细菌。

For example, in two thousand and seven, doctors in the Washington area said a boy died when a tooth infection spread to his brain. They said it might have been prevented had he received the dental care he needed. He was twelve years old.
例如，2007年华盛顿地区的医生表示，一个男孩由于牙齿感染蔓延至大脑而死亡。他们说，如果他做了所需的牙齿护理这事就能够避免。他当时才12岁。
