you have crossed out the thesis sentence
I crossed out the thesis ??? Are you sure? Do you mean this sentence " It will be discussed in this essay."??? This is not a thesis statement. A thesis is a statement that shows the main idea of the essay. In fact, for writing a thesis statement you should reword the topic. This sentence (It will be discussed in this essay) can be considered as a blueprint. A blueprint is a sentence that shows what issues are going to be argued in the body. In fact it is an outline of the essay. But what you wrote is not an interesting blueprint and for this reason I crossed it out.
The structure of the introduction should be similar to what I wrote below :
1) Motivator/General background: Write an interesting opening statement which gives some general information about the topic. It can be a "question", description", "short story", etc.
2) Thesis statement: Restate the topic as a thesis statement. This part of the introduction shows that the discussion will revolve around what.
3) If the prompt is an "agree or disagree" one, give your opinion as the third part of the introduction.
4) blueprint: This is a statement that connect the introduction to the body. Google "blueprint in writing" to get my point. You can also read about blueprint in the book entitled "The practical writer with reading"
By the way, is English your second language? Or it is a Foreign language for you? Second and Foreign languages are different.
Hope this answers your question.
