常见错误

❌ 错误:This is a crucial important meeting.
✓ 正确:This is a crucially important meeting. 或 This is a crucial meeting.

错误在于重复使用同义形容词。crucial 本身已表示“重要的”,直接修饰名词即可;若想强调,可用副词 crucially 修饰 important,但通常简洁表达更自然。

❌ 错误:It is crucial for we to finish on time.
✓ 正确:It is crucial for us to finish on time. 或 It is crucial that we finish on time.

错误在于介词 for 后使用了主格代词 we。for 是介词,后应接宾格代词 us;也可改用 that 从句,但需注意动词形式。
