1. Mr. Chen is one of these teachers who _______ (teach) you English.
陈老师是教你英语的这些老师之一。说明陈老师和其他老师是并列关系，即都是教你英语的老师。
2. Mr. Chen is the only one of these teachers who __________ (teach) you English.
陈老师是这些老师中唯一一个教你英语的老师。说明陈老师的唯一性，即这些老师中只有陈老师教你英语。
teach
teaches
一般来说定语从句紧接在先行词后面，如句一先行词是these teachers，而不是前面的one。因此定语从句的动词和these teachers保持一致。
而一旦给one of前面加上the only，那么先行词就变成the only one了，因为定冠词具有确定性，only具有唯一性。所以定语从句的谓语动词和one保持一致用单数。
