Summarize this article:

A hook is the way you get a reader interested in your essay. For a discussion essay, you could use a quotation from someone whose viewpoint you agree with, for instance. For an example or anecdote, start by telling a short story about something relevant to your topic. For instance, you might write the following for an essay on immigration, "When I was 4-years-old, my parents told me we were going on a long trip. After a bus ride, we spent nights walking, my dad carrying me most of the way. One day, we crossed a river. That day marked our first day in our new country." In the next few sentences, you'll move from your hook, which is broad, to your thesis statement, which is narrow. As you go, you'll bring up the main topic of your essay to give your readers an idea of where you're headed. You should present both sides of the issue in a neutral way before stating your thesis. For example, you might write, "Immigration is a highly-debated issue. It is controversial because some people fear how it affects the resources of the country the people are immigrating to, while others believe the improved quality of life for immigrants is what’s most important." After your transition sentences, you'll add your much narrower thesis statement, which tells the reader what you plan to argue. You may want to include some phrases the help the reader understand what you'll cover as your main points. For instance, your thesis statement might be, "Immigration is good for the country because it increases diversity, infuses the country with new talent, and broadens the population's perspective, and it should be encouraged with a few basic safeguards in place."
Begin with a hook such as a quotation or anecdote to engage readers. Introduce your topic in your transition sentences. Work on a thesis statement to establish your argument.
