Example Paragraph

Sample: Should Homework Be Banned?

[Thesis] In my opinion, homework should not be completely banned, but its amount should be significantly reduced. While homework has some educational value, excessive homework causes stress and reduces students' free time for extracurricular activities and family bonding.

[Argument 1] First of all, numerous studies have shown that too much homework leads to sleep deprivation among teenagers. According to Stanford University, students who spend more than 2 hours on homework per night suffer from sleep deprivation, which negatively affects their academic performance and mental health.

[Argument 2] Furthermore, homework often creates inequality. Students from low-income families who lack internet access or quiet study spaces cannot complete assignments as effectively as their wealthier peers, widening the achievement gap.

[Rebuttal] Admittedly, opponents argue that homework reinforces classroom learning. However, research shows that independent reading and creative projects can achieve the same goal without the stress of traditional worksheets.

[Conclusion] Therefore, schools should limit homework to 30 minutes per subject per night. This balanced approach maintains educational benefits while protecting students' well-being and promoting equity.

HORTATORY EXPOSITION TEXT

Definition, Structure & Language Features

What is Hortatory Exposition?
A hortatory text is a type of persuasive writing that aims to RECOMMEND or ADVISE the reader to do (or not do) something. Unlike argumentative text which presents both sides, hortatory focuses on PERSUADING the reader to take specific action.

Structure of Hortatory Exposition

THESIS
General statement / Issue
Introduce the topic and state your recommendation clearly.
Example: "Everyone should recycle waste regularly."
ARGUMENTS
Reasons WHY action should be taken
Present multiple arguments with evidence.
Example: "Recycling saves energy. It reduces pollution. It conserves resources."
RECOMMENDATION
Specific call-to-action
Tell reader EXACTLY what they should do.
Example: "Therefore, we should start recycling today by separating organic and inorganic waste at home."

Example Hortatory Text

Why We Must Recycle Waste

[Thesis] Recycling waste is one of the simplest yet most impactful actions we can take to protect our planet. Unfortunately, many people still underestimate its importance and throw away recyclable materials without thinking twice.

[Arguments] There are compelling reasons why everyone must recycle. First, recycling significantly reduces the amount of waste sent to landfills. According to EPA data, recycling and composting prevented 292 million tons of waste from reaching landfills in 2018 alone. Second, recycling conserves natural resources. Making paper from recycled materials uses 60% less energy than making it from raw materials. Furthermore, recycling helps combat climate change by reducing greenhouse gas emissions from manufacturing processes.

[Recommendation] Therefore, I strongly urge everyone to start recycling today. It takes minimal effort but makes a huge difference. Begin by separating your household waste into three categories: organic, recyclable, and residual. We must act now before it's too late. Remember: small actions lead to big changes. Let's make recycling a habit for our future generations!
