常见错误

❌ 错误:He is very spontaneous to help others.
✓ 正确:He is very spontaneous in helping others.

错误在于使用了'to help',而'spontaneous'通常后接'in + 动名词'或直接修饰名词,表示在某种行为中自发。

❌ 错误:The party was planned spontaneous.
✓ 正确:The party was spontaneous.

错误在于将'spontaneous'与'planned'并用,因为'spontaneous'强调未经计划,两者矛盾;应直接使用'spontaneous'描述事件。
