Some good options for writing an essay hook are to ask a question, set a scene or give a shocking fact. A hook is just a few sentences and can be funny, thought provoking, or mysterious, but should always draw the reader into the essay
Readers have a lot of material to choose from. If an essay appears boring, readers will quickly abandon it and move on to something more interesting. A hook is a device which demands readers’ attention and makes them want to read on.
A hook is typically only one or two sentences long and appears at the very beginning of the essay. Starting with a question is a tried and true way to hook the reader’s interest. For example, a scientific essay about the atmosphere might begin: "Have you ever wondered why the sky is blue?" A question invokes a response from readers. If they don’t know the answer, they will be tempted to read on.
Another good tactic is to begin mid-scene. A traditional, boring essay opening might read: "I decided to fly to India after graduating high school, so I booked a flight and packed my bags." A mid-scene hook, however, would read: "I was in the back of a taxi rushing through New Delhi traffic at noon." A mid-scene hook does away with unnecessary exposition and cuts right to the action. This approach works well for narrative, rather than informational, essays.
Another approach is to open with a shocking fact, such as, "As manay as 98 percent of Americans believe in leprechauns." This type of hook may outrage or amuse, but above all it grabs the reader’s attention.
