的 connects modifying phrases to nouns, forming complex noun phrases. The structure is [modifier + 的 + noun]. This is one of the most fundamental patterns in Chinese for building descriptive expressions.

This pattern explicitly states a reason or cause. Structure: [statement], 原因是 [explanation]. It's commonly used in formal writing and reports to provide clear causal relationships.

时 (or 时候) marks a temporal clause, meaning 'when' or 'while'. Structure: [action/state + 时], [main clause]. It indicates that two actions or states occur simultaneously or one occurs during another.

可能 is a modal verb expressing possibility or likelihood, similar to 'may' or 'might' in English. It's placed directly before the main verb to indicate that something is possible but not certain.

将 is a formal marker indicating future action, commonly used in written Chinese, news, and official statements. It's placed before the verb and is more formal than 会. Structure: [subject + 将 + verb].
