조건문 — if와 unless로 규칙과 선택 말하기

Jisoo is preparing a condition note about study rules for a stormy day. The first draft has many correct sentences, but the ideas do not yet move in a clear order. Jisoo reads the draft again and marks three parts: the topic, the helpful details, and the sentence that shows why the idea matters.

If the storm becomes stronger, students charge one backup phone and move away from the window. Unless the teacher gives a warning, the group keeps working quietly. The rules sound calm because each condition leads to one clear action.

During revision, Jisoo does not add facts from a website or copy a textbook example. The class uses only their own classroom situation, so every sentence can be checked by the writer. One partner asks, "What is the main point?" Another partner asks, "Which sentence helps the reader most?" These questions make the writing slower, but they also make it more accurate.

The final version is still short. It has one clear opening, two or three useful details, and one sentence that connects the details to the result. When Jisoo reads it aloud, the paragraph sounds calm and organized. That is the goal of this lesson: not a long essay, but a paragraph that a reader can follow without guessing.

If the storm gets stronger, close the window.
Unless the teacher gives a warning, keep working.
If the phone is low, charge it first.

My topic is ______.
One detail is ______.
This matters because ______.
Therefore, ______.
