We usually write a for and against essay in a formal style. When we write the essay, we need to discuss both sides of the argument to give a balanced view.
Introduction
First paragraph = we present the topic, but do not give our opinion.
Main body
Second paragraph = we give the arguments for the topic together with justifications and examples.
Third paragraph = we give the arguments against the topic.
We start each paragraph with appropiate topic sentences.
Conclusion
Last paragraph = we write a balanced personal opinion, or summarise the main arguments for and against.
We also need to use appropiate linkers to connect similar ideas and introduced opposing ideas.
Example: You have to write an article discussing the pros and cons of exercising to reduce stress.
More exercise, less stress?
Do you know how dangerous stress can be? It affects us both physically and mentally, so reducing stress is something that we should all try to do. While many people feel that the best way to get rid of stress is some form of exercise, there are other ways which are just as effective.
The benefits of physical exercise are obvious. First of all, keeping fit helps your body stay strong and healthy. Therefore you are less likely to get sick or suffer form stress-related health problems such as heart attack and cancer. Furthermore, exercise is a good way to get rid of frustration and anger because after exercise the brain produces hormones called endorphines which make us feel good.
Moreover, if you are out of shape, exercise can be quite painful. You may pull a muscle or injure yourself. Furthermore, exercising may even cause more stress since it will add to your already hectic schedule.
In conclusion, the best way to combat stress in our lives is to live a healthy life. As James Freeman Clark says, "Never hurry. Take plenty of exercise. Always be cheerful. Take all the sleep you need. You may expect to be well."
