4连板水发燃气：目前生产经营情况正常，市场环境、行业政策没有发生重大变化

Use “可能” before a verb phrase to say something is likely or possible; learners can attach objects/phrases after the verb (often with “存在/有”等). It hedges statements and is common in business/news Chinese.

Combine verbs like “提醒/特别提醒” with a person and “注意” + noun/phrase to politely warn someone to pay attention.

“由” introduces the starting point and “增至/升至...” gives the new value, often used for numbers or amounts to describe increases.

Use “动词＋后” to link sequential actions, indicating what to do after completing the first action.

“没有” negates completed actions or states (often with verbs like “发生/改变”) to say something did not happen or change.
