陷阱
⚠️vital vs. crucial:不可或缺 vs. 关键时刻
The timing of the intervention was crucial — a delay of even a few hours could have resulted in permanent damage.
crucial = vital(关键的,至关重要,可以互换)
crucial(在某一特定时刻或决策点上不可缺少——强调「时机的关键性」);vital(不可或缺,强调「缺少即有严重后果」,偏向长期或系统性的必要性);此句强调「时机」的决定性,用 crucial 更准确
干预的时机至关关键——哪怕推迟几个小时都可能造成永久性损害。(crucial = 在关键决定点上不可缺少,比 vital 更强调「时机的决定性」)
⚠️it is vital that + 虚拟语气

每位公民了解其在法律体系中的权利和责任至关重要。(understands 错误,应改为 understand)
it is vital that 后接虚拟语气(should + 动词原形,或直接用动词原形),不用陈述语气
