1. AIDS
AIDS, acquired immune deficiency syndrome, is a disease which destroys the natural method the body uses to protect against other diseases. It is a disease caused by the HIV (human immunodeficiency virus), but AIDS is different from HIV in that the former usually causes death while HIV may lead to AIDS. HIV is spread in three ways: (1) contact with infected blood; (2) sex; (3) mother-to-child. AIDS usually develops in four stages: (1) In the first stage, there is only infection by HIV and antibody (抗体) production. (2) In the second stage, the lymph nodes (淋巴结) enlarge (肿大). (3) In the third stage, an infected person may begin to have such signs (症状) as tiredness, fever, and night sweats. (4) In the last stage, AIDS is diagnosed when a person develops certain uncommon, life-threatening illnesses, for example Pneumocystis carinii pneumonia(卡氏肺囊虫肺炎 ).

3. HIV
HIV is the human immunodeficiency virus. This is the virus that spreads through contact with infected blood, infected sexual partners or within the womb of an infected pregnant mother. After infecting a person, HIV can remain hidden in the body for long and different periods of time until it becomes active and develops into AIDS for which no known cure exists. The virus spreads very fast once contact has been made with an infected source. In-depth coverage on AIDS and HIV can be found from http://dailynews.yahoo.com/fc/Health/AIDS___HIV

A beauty shop is a business place where women go "to have their hair done," i.e., washed, curled, coloured, etc., or their fingernails or skin treated. The shop sells the 'thought' of beauty. A client should feel/look more beautiful after a visit to the beauty shop. Women who use such shops often have weekly appointments.
