not until 引起的時(shí)間狀語(yǔ)置于句首時(shí),句子的主謂應(yīng)部分倒裝.由 not until 引導(dǎo)的時(shí)間狀語(yǔ)從句位于句首時(shí),主句應(yīng)部分倒裝,從句語(yǔ)序不變.如：

直到 1998 年他才回到家鄉(xiāng).
Not until Father came back did we begin to have supper last night.
昨晚直到父親回來(lái),我們才開(kāi)始吃晚飯.
注意：當(dāng) not until 引導(dǎo)的狀語(yǔ)或狀語(yǔ)從句用于強(qiáng)調(diào)句型時(shí),句子的主語(yǔ)不倒裝.如將上兩句改為強(qiáng)調(diào)句應(yīng)為：
It was not until 1998 that he returned to his hometown.
It was not until Father came back that we began to have supper last night.
