It is so important to be able to develop a topic sentence in the IELTS Writing Exam. If you can’t support your main idea with explanation or examples, you simply aren’t fulfilling the requirements for coherence and cohesion. This is a difficult skill to master, but there are ways to practice it.
Look at the following topic sentences. Try to write two supporting sentences for each one.
In many countries, schools are facing increasing problems with pupils’ behavior.
Obesity is a major health problem in many countries and children are just as much at risk as adults are.
Remember that your sentences must follow on logically. That means they must flow naturally from one point to the next – in other words, developing an idea. Also, you should avoid repeating words or phrases where possible.
Here are my two answers for the above topic sentences.
In many countries, schools are facing increasing problems with pupils’ behavior. One such example is truancy, which is a significant problem in the United Kingdom. It has gotten so bad lately that authorities have begun fining parents to solve the problem.
Obesity is a major health problem in many countries and children are just as much at risk as adults are. Part of the problem is that fast food restaurants are advertising directly to children. Children don’t have the ability to resist these advertisements and are easily captivated by cheap marketing ploys.
In the first example, I developed the topic sentence by mentioning one kind of behavioral problem – truency (which means being absent from school). I further developed this by explaining how severe the problem has become.
In the second example, I developed the topic sentence by elaborating upon the general problem of childhood obesity, showing why children are getting so fat. Each sentence builds logically upon the previous one.
