LEARN IN CONTEXT
Read and listen across several real contexts
This lesson uses the number and type of texts that fit the topic. Learn the same language across different situations instead of forcing everything into one dialogue.
Core textShort article
咖啡店涨价后，顾客真的都走了吗
Why this text is here: Read a small economic case with price, cost and customer segmentation.
一家社区咖啡店因原料和房租上涨，把主要饮品价格提高了约百分之八。老板原本担心销量会明显下降，但一个月后总订单只减少了百分之三。进一步看数据才发现，早高峰的通勤顾客变化不大，下午长时间停留的顾客减少较多。A neighborhood café raised major drink prices by about 8% due to ingredient and rent increases. Orders fell only 3%, but customer groups changed differently: commuters were stable while long-stay afternoon customers fell more.
这说明“涨价导致顾客离开”并不是一个足够完整的结论。不同消费者对价格、地点、时间和替代选择的敏感程度不同。销量变化未必只由价格决定，还可能受到天气、附近新店和促销活动影响。要么继续观察更长时间，要么设计小范围优惠测试，不能用一个月的数据预测全年。Price alone is an incomplete explanation. Different consumers respond differently to price, location and alternatives, and weather or competitors may matter. The shop should either observe longer or run a limited promotion test rather than extrapolate one month to a year.

Degree adverbs
特 / 异常 / 较为 + adjective
These adverbs express degree in different registers. 较为 is especially common in neutral formal descriptions.
Zhè xiàng guīdìng jiàowéi fùzá, dì yī cì bànlǐ de rén róngyì hūlüè xìjié.这项规定较为复杂，第一次办理的人容易忽略细节。This rule is relatively complex, and first-time applicants can easily miss details.
Negative adverb 未必
未必 + predicate
未必 marks that a conclusion is not necessarily true. It is useful for cautious evaluation and evidence-bounded reasoning.
Diǎnjīliàng hěn gāo wèibì shuōmíng suǒyǒu yònghù dōu rèntóng zhège guāndiǎn.点击量很高未必说明所有用户都认同这个观点。A high click count does not necessarily mean all users agree with the view.
Alternative compound sentence
要么……，要么……
Use 要么…要么… to present two alternatives when a choice is required.
Yàome yáncháng shìyùnxíng shíjiān, yàome suōxiǎo shǒupī kāifàng fànwéi.要么延长试运行时间，要么缩小首批开放范围。Either extend the trial period or reduce the scope of the first launch.
