This is some advice on how to write an article:
1. Register: Semi formal.
2. Readers: Consider who you're writing for and why.
3. Title: Choose a title which is appropriate for your aim.
4. Introduction: Use it to get readers' attention. You could use a humourous comment, a rhetorical question or a worrying fact.
5. Middle paragraph: To achieve an impersonal tone here, you could use passive voice structures, noun phrases and adverbs.
6. Conclusion: Include a short summary of your previous ideas. You may also include your opinion.
7. Paragraphs should be ordered logically.
