来自世界不同地方的六位学生在美国相遇。他们都是交换学生,到美国大学就读一个学期,学习英语,了解美国文化,同时修专业课程。英语“日常会话” (Everyday Conversations)系列围绕这六位学生在美国的经历展开。这套材料适于中级或中级以上英语水平的学生使用。
两个学生(Peter and Akinyi)谈清洁安全饮水的重要。
Peter: Is that a straw?
Akinyi: Yes. Isn’t it great? This is a solution to water scarcity.
Peter: You’re starting to sound a bit like Lee. Are you studying water scarcity in a class? And how is a straw the solution?
Akinyi: I’m studying the business model of one company that creates these filter straws. Believe it or not, this straw is a portable water purifier.
Peter: Is there really a large need for a water purifier to be portable?
Akinyi: Definitely. We all know that clean and safe water is essential to healthy living. But lack of clean water can affect the education of many children in the world.
Peter: Really? How?
Akinyi: Well, for example, students might get sick from drinking unsafe water and miss school.
Peter: And if students can carry filter straws, then they can always drink safe water?
Akinyi: Exactly. The straws have iodine, charcoal and filters – these combine to reduce harmful particles and remove bacteria. And they last up to a year!
Peter: Wow. That seems like a great solution for people without access to clean and safe drinking water.
