the reason whe he was late was that he got up late主句是 the reason was that the got up late. 主語(yǔ)the reason 謂語(yǔ) was表語(yǔ) that he got up late從句why he was late主語(yǔ)he 謂語(yǔ) wa...where 和why都是關(guān)系副詞吧 關(guān)系副詞只能在引導(dǎo)的句中中做狀語(yǔ)嗎？在第一個(gè)句子中，why是關(guān)系副詞第二個(gè)句子 where 從句并非定語(yǔ)從句， 是表語(yǔ)從句， 所以只能算從句引導(dǎo)詞，不能算關(guān)系副詞。
