Voice 2: Some diseases can kill a person. But there are other diseases that make life painful. Schistosomiasis is this kind of disease. Schistosomiasis causes many different problems in a person's body. But to understand what happens to a person's body, we must first know how a person gets schistosomiasis.
聲音2：有些疾病可致人死亡。其他疾病則會令患者的生活痛苦不堪。血吸蟲病就屬于這類疾病。血吸蟲病會在患者身體里引發(fā)許多問題。而為了了解患者的身體會發(fā)生什么，我們必須首先知道為什么會感染血吸蟲病。
Voice 1: Schistosomiasis is caused by a very small organism. This organism lives in dirty water. If a person's skin touches this dirty water, that person is at risk. The organisms may enter his body. The organisms sense movement from a person. They like the chemicals from a person's body. The organisms also produce a chemical. This chemical lets them enter a person's body.
聲音1：血吸蟲病由一種極小的生物所引發(fā)。這種生物生活在污水中。如果有人的皮膚接觸到這一污水，那就會面臨風險。這種生物會進入他的身體。該生物能感知到人的移動。它們喜歡人體中的化學物質。這種生物還會產(chǎn)生一種化學物質。該化學物質會讓它們進入人體。
Voice 2: The organism moves through the body, from the skin, to the lungs, to the liver. There, it feeds on red blood cells. When both male and female organisms meet in the liver, they reproduce. The female organism releases eggs into the person's body. This is where the serious problems start.
聲音2：該生物會在人體內(nèi)移動，從皮膚到肺部再到肝臟。它們會以肝臟的血紅細胞為食。當雄性生物和雌性生物在肝臟中相遇后，它們就會繁殖。雌性生物會在人體內(nèi)產(chǎn)卵。這就是嚴重問題的起始點。
