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。
一个学生 （Peter）和同学（Lee）谈到他将进行的雨林之旅。
Lee: I’m so jealous that you’ll be spending part of your winter break in the rain forest. As an environmental science major, I’d love to go to the rain forest to study it.
Peter: I’m really excited to go. I’ll be volunteering at a school for two weeks. I’ll be helping one of the classroom teachers there.
Lee: Are you nervous?
Peter: Not about working in the school. I’m just worried about malaria.
Lee: Right. Mosquitoes in that area carry malaria. But can’t you get vaccinated or something?
Peter: There’s no vaccination for malaria, but I can take a drug. I will have to take a pill every day while I’m there.
Lee: Definitely don’t forget to take it. Malaria can kill you.
Peter: I know. Fortunately, governments and NGOs are increasing awareness about the disease and giving people mosquito nets to help with disease prevention.
Lee: That’s good. So you’ll be sleeping under a mosquito net too?
Peter: I think so!
