Part I. Brief statements Based on the Unit
This unit mainly talks about deadly diseases and attitudes towards AIDS, cancers, etc. All the activities, including Warming up, Listening, Speaking, Reading and Writing, focus on this topic. Through this topic, the students not only get more information about diseases, but also learn how to keep a right and positive attitude towards disease and people with disease.
In addition, the students can learn some useful language points through the materials provided in each part, especially a lot of words and phrases, which are very helpful for the students to build up vocabulary about diseases. The Grammar—the Subjunctive Mood is also important. The given materials and exercises give the students an opportunity to learn grammar by using it. It helps the students learn to talk about things that are not certain to happen as well as imaginary or unreal events and situations.
All of the activities are helpful for the students to improve their knowledge about language and their skills to use language.

Part II . Background Information
What is AIDS?
AIDS is a disease that breaks down a person’s immune system。Once a person develops AIDS，he or she usually dies from the disease within a few years 。There are medicines and treatment available，but they are expensive and do not cure them。
WHAT DO "AIDS" MEAN?
AIDS stands for Acquired Immune Deficiency Syndrome:
• Acquired means you can get infected with it;
• Immune Deficiency means a weakness in the body's system that fights diseases.
• Syndrome means a group of health problems that make up a disease.
AIDS is caused by a virus called HIV, the Human Immunodeficiency Virus. If you get infected with HIV, your body will try to fight the infection. It will make "antibodies", special molecules that are supposed to fight HIV.
When you get a blood test for HIV, the test looks for these antibodies. If you have them in your blood, it means that you have HIV infection. People who have the HIV antibodies are called "HIV-Positive". Fact Sheet 102 has more information on HIV testing.
Being HIV-positive, or having HIV disease, is not the same as having AIDS. Many people are HIV-positive but don't get sick for many years. As HIV disease continues, it slowly wears down the immune system. Viruses, parasites, fungi and bacteria that usually don't cause any problems can make you very sick if your immune system is damaged. These are called "opportunistic infections" (see Fact Sheet 500).

HOW DO YOU GET AIDS?
You don't actually "get" AIDS. You might get infected with HIV, and later you might develop AIDS.
You can get infected with HIV from anyone who's infected, even if they don't look sick, and even if they haven't tested HIV-positive yet. The blood, vaginal fluid, semen, and breast milk of people infected with HIV has enough of the virus in it to infect other people. Most people get the HIV virus by:
• Having sex with an infected person.
• Sharing a needle (shooting drugs) with someone who's infected
• Being born when the mother is infected, or drinking the breast milk of an infected woman.
Getting a transfusion of infected blood used to be a way people got AIDS, but now the blood supply is screened very carefully and the risk is extremely low.
There are no documented cases of HIV being trans
