Voice 2: Over four million people die from strokes each year. The most common kind of stroke is an ischemic stroke. An ischemic stroke can happen when something blocks one of the blood tubes leading to the brain. These tubes, or arteries, carry blood and oxygen to the brain. So a blocked artery prevents oxygen reaching the brain. A 'stroke' is when some of cells in the brain die as a result of the blocked artery.
聲音2：每年有超過400萬人因中風死亡。最常見的中風是缺血性中風。通往大腦的血管被堵住就會引起缺血性中風。這些血管，或者說這些動脈為大腦運送血液和氧氣。所以，動脈堵塞會導致氧氣無法抵達大腦。當大腦的一些細胞因為動脈堵塞而死亡時，就會引發(fā)中風。
Voice 1: Melissa Welch worked in a store after school. One day, she felt sick. It seemed like the room was going round and round. Another worker found Melissa at the back of the store. Melissa was unable to speak. She could not stand up. A blocked artery was starving her brain of oxygen. Melissa was experiencing the beginnings of a stroke.
聲音1：梅麗莎·韋爾奇放學以后在一家商店工作。有一天，她感覺到很不舒服。房間好像一直在轉圈。另外一名工作人員在商店后面發(fā)現了梅麗莎。當時梅麗莎無法說話。她也不能站起來。動脈阻塞導致她大腦缺氧。梅麗莎當時處于中風的初始階段。
