课件29张PPT。Welcome to the unit M10 Unit 3Protecting ourselvesUnit 3 课件描述：
1. 通过呈现一些图片来了解艾滋病、吸烟、酒后驾车等对我们人类可能造成的危害，以达到让学生学会保护自己。
2. 要求学生初步掌握在一些情境下应该用何种语言表达自己的思想。 Lead in:
What things are bad for our health?Warning: Smoking is bad for our health.Say No to drugs!
Don’t drink
and drive!What do you know about Aids?AIDS1.What is the poster about?2. What should we do or not do to stay safe from the dangers shown in the posters? This poster is about Aids. It shows a poster of people holding a big picture that is covered in handprints. I think that they choose this picture because the handprints are different colours, and this shows that Aids can affect everyone, no matter what their skin colour 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.
The words ‘STOP THE CHAIN OF AIDS’ can be seen on the poster. The poster encourages us to stop spreading this disease.
We need to make sure that we do not become infected by Aids. 1. What is the poster about?
2. What should we do or not do to stay safe from the dangers shown in the posters? Everyone knows smoking causes great harm to one’s health, but many smokers just keep on smoking. The human skull with a cigarette between its lips shows that the result of smoking is death. Smoking can cause various deadly diseases, such as lung cancer, heart trouble and high blood pressure. Smoking is one of the biggest killers in the world. Although most people know the dangers of smoking, many find it very hard to stop smoking because cigarettes are so addictive.What is the poster about?
What should we do or not do to stay safe from the dangers shown in the posters? The warning ‘Say No to drugs!’ tell us that we must not take drugs. There are some drugs in the poster. 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. The theme of this day in 2006 is ‘Drugs are not child’s play’. It aims to tell people that drugs are not fun and are not safe. Let’s just say no to drugs.
1. What is the poster about?
2. What should we do or not do to stay safe from the dangers shown in the posters? This poster shows a damaged car that has obviously been in an accident. The driver may be dead. From the world ‘Don’t drink and drive!’ we can know what caused the accident. Next to the car lies a bottle of what looks like alcohol. The driver was probably drinking alcohol before driving. In many countries, driving after drinking is the main cause of traffic accidents every year. Especially in recent years, with the rapid increase in the number of cars on the road, more traffic accidents have taken place because of driving after drinking. Looking at the poster every one of us must remember that no one should drive after drinking. We should consider both our own lives and the lives of others, and drive safely.Discussion1. Why do you think people do things that are harmful to their health and lives?
I think there are a number of reasons why people do these things. The first reason is that they do not know how serious the results of their actions are. People may be curious about taking drugs and want to try something new. They may think, ‘I will just try this once, and I will not become addicted to it.’ People may also be influenced by their idols smoking, and think it is cool, so they copy their idols and smoke too. Some people just do not obey the law. For instance, no one should drive after drinking.However, some people think that they will be lucky and nothing will happen to them. Finally, some people do not have enough knowledge about how to protect themselves. Maybe they do not know that one can be infected with Aids through a blood transfusion, when the hospital has not checked for Aids, or unprotected sex.2. What do you know about Aids?
Aids is a deadly disease, and that there is no cure. The medicines used to treat Aids are very expensive, so many people cannot afford to pay for them. For many Aids victims, there is nothing they can do. The situation is very serious around the world, especially in African and Asia. African has the highest number of HIV-positive people in the world. Some children are now being born with HIV because their mothers were infected with HIV when they were pregnant.
3. Can you think of some other bad habits that harm people’s health and lives?
Some young people, including some university and high school students, are addicted to computer or video games. They often play these games deep into the night. Some high school students even miss school and do not do their homework in order to play these games. Some may even lie to their parents or steal money so that they can afford to play games online. Being addicted to video games not only does harm to their health but can also ruin their future. Other bad habits include students going to school without breakfast in the morning. Some like juice or fizzy drinks, and do not want to drink fresh water. Some eat too much meat and almost no vegetables every day.Homework1. Find more things which affect people’s health and then write them down in English.
2. Preview Reading and learn new words and phrases in it.
