Use the same or similar wording as in the essay topic. If the question sounds like "Discuss recent developments in communication technology" ("Consider modern developments in communication technology on try this"), in the introduction you can write: "This essay will consider recent developments in the field of communication technology ..." ("In this The essay will be considered modern developments in the field of communication technology ... "). More certainty: do not leave the reader room for doubt.
You can also use these words and phrases that emphasize your work plan, for example:
The essay is divided into four sections ... ("This essay consists of four parts ...")
It will first consider ... ("First viewed ...")
It will then continue to describe ... (“Then we will continue to describe ...”)
The third part compares ... (“The third part compares ...”)
Finally, some conclusions will be drawn as to ... (“And finally, some conclusions will be made regarding ...”)
