小升初英語語法強調(diào)句知識點：如何對not… until…句式進行強調(diào)
    對not…until句式的強調(diào)有固定的句型，即It is / was not until…that…如：
    It was not until yesterday that I noticed it.
    直到昨天我才注意到此事。
    It was not until I saw Mary that I felt happy.
    直到見到瑪麗我才高興起來。
    It was not until you had explained how that I managed to do it.
    直到你給我解釋了理由，我才會做的。
    It was not until she took off her dark glasses that I realized she was a famous film star.
    直到她取下墨鏡，我才意識到她是一位影星。
    It was not until I met you that I knew real happiness.
    直到我遇到你以后，我才真正體會到幸福。
    It was not until you had explained how that I managed to do it.
    直到你給我解釋了理由，我才會做。
    請看兩道題：
    (1) It _______ we had stayed together for a couple of weeks _______ I found we had a lot in common.
    A. was until； when B. was until； that
    C. wasn’t until； when D. wasn’t until； that
    答案為D。此題考查not…until…句式的強調(diào)形式——It was not until…that…的用法。注意不要想當然地將其中的that換成when。
    (2) It was not until she got home _______ Jennifer realized she had lost her keys.
    A. when B. that
    C. where D. before
    答案為B?？疾閚ot…until…的強調(diào)形式，其基本結(jié)構(gòu)為it was not until….that…形式。
