这个题型，it is …… that……中that后面的句子是主语，it指代that后面的句子。when不能被it指代

经查证：只有一种用法，就是that

It is / was not until…that…是固定的强调句型，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. 直到见到玛丽我才高兴起来。 It was not until you had explained how that I managed to do it. 直到你给我解释了理由，我才会做的。 It was not until she took off her dark glasses that I realized she was a famous film star. 直到她取下墨镜，我才意识到她是一位著名影星。 It was not until I met you that I knew real happiness. 直到我遇到你以后，我才真正体会到幸福。 It was not until you had explained how that I managed to do it. 直到你给我解释了理由，我才会做。
