A reviewed Daily Basics and Core Review mapping trace using an established formal Pattern.
Sentence Analysis
The source sentence is segmented as 问题 / 非常 / 困难. Its canonical Chinglish trace is problem / very / difficult, producing “problem very difficult.” Each surface token is linked to a real Word record and to the primary mapping shown in the source sequence. This preserves Chinese semantic order before any English grammar repair is considered. The mapping is contextual rather than a claim that every dictionary sense of these words is interchangeable. Pattern CWB-P020 describes the visible roles in this Daily Basics and Core Review example. The subject, action or state, and target remain aligned with their Chinese units. Function words that exist only because English grammar requires them are not invented as Chinglish tokens. Likewise, canonical tokens remain in their approved base form instead of copying English tense, agreement, article, or plural marking. Natural English renders the same message as “The problem is very difficult.” Its structure may add an article or copula, change agreement, or choose a more idiomatic order. Those changes are shown for comparison, not silently mixed into the Chinese trace. A learner can therefore see which meaning units came from Chinese and which features belong only to idiomatic English. The dependency buffer is also intentional: every annual Word used here was assigned to an earlier production week, so it is due to publish before this Sentence. Editors should reject the sentence if a token mapping changes, if the Chinese no longer matches the displayed trace, or if the natural rendering changes the intended message. The example is suitable for general language learning only and does not extend into professional advice.
