2. Who is the intended reader How can we know
To explain a teenage problem and suggest solutions.
Young people, especially teenagers. In Para 1, the author discusses it is easy for teenagers to form bad habits. Para 7 starts with “for young people”.
Purpose
What methods are used to explain the topic in this exposition
There is a famous saying based on the philosopher Aristotle, “We are what we repeatedly do.”
For example, we could try to replace a negative routine with something more positive.
According to modern psychology, we must first learn about the “habit cycle”, which works like this:
example
quotation
definition
However, there is no “magic pill” or delete button that will help you;
metaphor
chart
Language Features
Habit makes your character that finally makes your final fate.
