what-从句作主语时的主谓一致问题

“What may seem like small messages at the moment add up to big ones over time,” says an expert.

请问老师：这里是what引导的主语从句What may seem like small messages at the moment，后面却用动词原形是不是不对？要改为adds吗?

What may seem like small messages at the moment add up to big ones over time.

你的句子用单数动词肯定没问题，但用复数动词也不是不可以。因为从句中的 messages 为复数，表明 what 也具有复数意义，比较原句可以这样改写：

The things that may seem like small messages at the moment add up to big ones over time.
