参考答案

                                       AIDS
    AIDS is a life-threatening sickness that arracks the body’s natural defense system against disease. It can destroy the body’s ability to protect itself.
    AIDS itself does not kill. But because the body’s defense system is damaged, the patient has little ability to fight off many other diseases, such as pneumonia, cancer, blindness and mental disorders.
    The AIDS virus is carried in a person’s body fluids. The virus can be passed sexually or by sharing instruments used to take intravenous drugs. It also can be passed in blood products or from a pregnant woman with AIDS to her developing baby.
    Many stories about the spread of AIDS are false. You cannot get AIDS by working or attending school with someone who has the disease. You cannot get it by touching drinking glasses or other objects used by such persons. Experts say no one has gotten AIDS by living with, caring for or touching an AIDS patient.
