The key idea
To make a paragraph longer, don't repeat the same idea in other words. Help the reader with three questions: what are you saying, why is it so, what does it look like?
Idea → explanation → example is a good starting structure. This is not a required number of sentences. Some ideas need an extra result and some a comparison.
The job of an example is to demonstrate the idea; don't invent fake research or percentages as evidence.
See an example
Libraries give students a quiet place to study. This matters for those who share a small home with several family members. For example, a student preparing for exams can use a library desk when studying at home is difficult.
The first sentence states the idea, the second explains why it matters, and the third shows the situation. Three separate, unrelated advantages are not listed.
Now you try
Extend this idea with two sentences:
Part-time work can help students develop useful skills.
In one sentence, explain which skill develops and how. In the second sentence, give a concrete example of a job.
A personal draft. It is not saved when you leave or automatically graded.
Reveal the answer and explanation
Answer and explanation
Possible continuation: Working with customers teaches students to explain problems clearly. For example, a student in a café may need to resolve a mistaken order politely.
Check your own answer: did you repeat the phrase “useful skills”, or did you name one skill? Does the example show that skill? If there is a direct link, the paragraph is developing.
