❌ 错误:He gave a keynote about the project.
✓ 正确:He gave a keynote speech on the project.

keynote 作为名词时,通常不单独使用表示“演讲”,而应搭配 speech 或 address,如 keynote speech。介词 about 不如 on 正式,在学术或商务场景中常用 on。

❌ 错误:The meeting's keynote is very important.
✓ 正确:The keynote of the meeting is very important.

中文学习者可能省略介词 of,直接使用所有格形式,但在英语中,keynote 常与 of 连用表示所属关系,如 the keynote of the meeting,以更准确地表达“会议的基调”。
