常见错误

❌ 错误:He gave a keynote address about his travel experiences.
✓ 正确:He gave a keynote address on global tourism trends.

错误用法中,“travel experiences”过于个人化,不符合“keynote address”通常涉及重大主题或政策的正式语境;正确用法应聚焦更宏观或专业的主题。

❌ 错误:I will keynote address at the party tonight.
✓ 正确:I will deliver a keynote address at the conference tomorrow.

错误用法中,“keynote address”被误用作动词,且“party”场景过于随意;正确用法中,“deliver”是常用动词搭配,“conference”更符合正式语境。
