2. Brainstorming Q1: While talking about AIDS, what other diseases can you think of? Individual work: Let students brainstorm the names of diseases, such as cold, headache, toothache, diarrhoea, cut, coughing, scald, insomnia, heart attack, cancer, AIDS, etc. (With the development of science and hi-tech, many diseases can be cured. But for now, AIDS is still incurable, so it’s a deadly disease.) 3. How much do you know about AIDS? 1) Pair work—questions for discussion What’s the full name of AIDS? Can AIDS be transmitted? In what ways can it be transmitted? What kinds of people are likely to get AIDS? Do people with AIDS look healthy at first? Is it safe or dangerous to stay or to be friends with them? Why? (Students don’t have to give the exact answers. These questions will help them think about this disease—AIDS.) 2) AIDS QUIZ (individual work) 1) AIDS quiz (p.49)—check students’ knowledge about AIDS. 2) Picture quiz —Can the AIDS virus transmitted via the following routes? Summary: Medical studies show that the AIDS virus cannot be transmitted via the following routes: cups, glasses, toilet seats, swimming pools, mosquitoes, other insects or giving blood. So it’s safe to be friends with AIDS patients. II. Listening (WB) 1. Pre-listening: Go through EX1&2 in Part1 and guess “What do the letters HIV and AIDS stand for?” 2. While-listening: Listen to the tape and finish exercises in Part1&2. (Make good use of some pictures and a flash “HIV-cycle” in the PowerPoint) 3. Post-listening: Suppose you are a publicist of AIDS, please give an oral report about it to the whole class. III. Talking (Optional) Role play: Work in groups. Imagine that the headmaster of a school has found out that one of the students has HIV. The student’s family has kept it a secret until now and the headmaster only learnt the truth last week. He had called a meeting to decide what to do. (责任编辑：admin)
