Finally, designing the last sentence in this way has the added benefit of seamlessly moving the reader to the first paragraph of the body of the paper.
Try instead to be more general and you will have your reader hooked.
The middle paragraphs of the essay are collectively known as the body paragraphs and, as alluded to above, the main purpose of a body paragraph is to spell out in detail the examples that support your thesis.
Following the thesis, you should provide a mini-outline which previews the examples you will use to support your thesis in the rest of the essay.
Not only does this tell the reader what to expect in the paragraphs to come but it also gives them a clearer understanding of what the essay is about.
Active voice, wherein the subjects direct actions rather than let the actions "happen to" them – "he scored a 97%" instead of "he was given a 97%" – is a much more powerful and attention-grabbing way to write.
At the same time, unless it is a personal narrative, avoid personal pronouns like I, My, or Me.
For proof of this, consider examples from both science and everyday experience.
Because this is the first paragraph of your essay it is your opportunity to give the reader the best first impression possible.
The introductory paragraph not only gives the reader an idea of what you will talk about but also shows them how you will talk about it.
Put a disproportionate amount of effort into this – more than the 20% a simple calculation would suggest – and you will be rewarded accordingly.
