Lesson 12 · 昨天下雪了
Describe weather changes and simple body feelings, use sentence-final `了` for a new situation, and use `太...了` for high degree.

Listen and Read
First listen to how two classmates talk about weather and how they feel.
Core Words
First learn to say weather and feelings clearly.
Pattern: `新情况 / 新状态 + 了`
This lesson first teaches `了` at the end of a sentence.
Sentence-final `了` often shows a change or a new situation. When it starts snowing, say `下雪了`. When someone becomes sick, say `我生病了`.
Quick Practice
Recognize when to use sentence-final `了`.
Choose the option that shows a new situation.
Pattern: `太 + 形容词 + 了`
Use this pattern to show a high degree with stronger feeling.
`太...了` often shows a high degree and an exclamatory tone. It can be negative, as in `太冷了`, or positive, as in `太好了`.
Core Words
These words help you talk simply about illness and advice.
Learning Note
When someone is sick, first learn three very basic things to say.
HSK1 does not need complex symptom descriptions. First read `喝热水` and `回家休息` smoothly. `有点儿 + adjective` means a little, as in `有点儿冷`; `喝 + 点儿 + thing` means drinking a little of something, as in `喝点儿热水`.
Quick Practice
Choose the most natural degree expression.
Choose the sentence that uses `太...了`.
Learning Note
Turn weather and body feelings into two short question-answer groups.
Repeat first. In the weather sentence, only replace `下雪` with `下雨`. For the degree sentence, practice `今天太冷了` and `今天太忙了` separately; do not put `忙` into the weather sentence.
