It was not until 11o"clock yesterday that tom finished all his homework,为啥用that不用when?

It was not long until ... It was not until 11oclock yesterday that tom finished all his homework,为啥用that不用when? not ...until it was not until Not until句型转化 帮我写三组句子 30分 先送上not ...until it was not until Not until 改错:It was not 8 o'clock until he arrived home . it was not eight o'clock until he arrived home.为什么?需要肯定的回答 it was not until when...与it was not until that...区别,强调句型用哪个. it was not until.did.和it was not until .that.这两个有什么区别 请问是it was not until 1990s还是It was not until the 1990s it was not until 和 it was until 的区别,请详细一点. it is not until that 和it was not until that it was not until--------------that/when 的区别如题 It was not until midnight did he come back. it was not until yeasterday to have we knew it.为何until不能换为till? It was not until .that.是句型,有没有It was not until.when.的形式,举个例句 It was not until the late sixteen hundreds that women began to perform professionally as dancers.it was not until It was not until 12 o'clock that I-------to sleepa had gone b was going c went d would go 英语翻译2、I did not go home until it was about five or six o'clock3、it this way i spent my holiday happily it was __(until/ when) he was 11 that his talent for writing became obvious.选哪个答案对呢?为什么?如果用not until
