Now let’s study the pictures!

Picture 1 This poster is about Aids. It shows a poster of people holding a big picture that is covered in handprints. The handprints are different colors, and this shows that Aids can affect everyone, no matter what their skin color is or what country they are from. This tells us that Aids is an international problem that we have to work together to try and fight.

Aids: acquired immunodeficiency syndrome ( 获得性免疫缺陷综合症 ) HIV: human immunodeficiency virus ( 人类免疫缺陷病毒 ) World Aids Day: 1 December Aids patients/victim: people who have Aids and are suffering from it HIV carriers: people who are carrying the virus called HIV

Picture 2 Everyone knows smoking causes great harm to one’s health, but many smokers just keep on smoking. This poster wants to persuade them to give up cigarettes. The human skull with a cigarette between its lips shows that the result of smoking is death.

Picture 3 The warning ‘Say No to drugs!’ tells us that we must not take drugs. Drug- taking is a global problem, so the whole world is paying special attention to this problem. 26 June is International Day against Drug Abuse and Illicit Trafficking.

Picture 4 This poster shows a damaged car that has obviously been in an accident. From the words ‘Don’t drink and drive!’ we can know what caused the accident. The driver was probably drinking alcohol before driving. In many countries, driving after drinking is the main cause of traffic accidents every year.
