[解释] when cooled的构成：连词+过去分词，相当于when 引导的状语从句when it is cooled

如果when／while引导的时间状语从句中的主语与主句的主语相同，常常可用when／while + 现在分词短语或者过去分词短语的结构来代替。

1). When offered help, you should say “thank you” or “it’ s very kind of you”.

2). Having been told

3). following

3.12. ...but it was not until five days later that Bell sent his first telephone message to his assistant Watson. …但是贝尔是在五天以后才跟他的助手华生通了第一次电话。

该句是"It is/was not until+被强调部分+that+其他"结构。

句中用了"not ...until ..."的强调句结构，此句型只用until，不用till。但如果不是用在强调句型中，till与until可通用；另外主句中的否定词not 要提出来，放在until之前一起强调，因此that后面的从句要用肯定句，不能再用否定句。

He didn't go to bed until/till his wife came back.=It was not until his wife came back that he went to bed.

直到他的妻子回来他才睡觉。

温馨提示

not until置于句首时，要用部分倒装句型，这时要注意从句不倒装，只倒装主句。

Not until last week did they find the lost bike. 直到上个星期他们才找到丢失的自行车。

Not until my son had entered the university did he realize the importance of time. 我的儿子直到上了大学之后才意识到时间的重要性。

单项填空

①It was

midnight

back home after the experiment.

A. until; that he went

B. until; that he didn't go C. not until; that he didn't

D. not until; that he went ②Not until I began to work

realize how much time I had wasted.

didn't I

B. did I

C.

I didn't

D. I

①解析：选D。从题干和选项很容易看出这是一个含有not until 的强调句。基本句型为"It is/was not until+被强调部分+that+其他成分"，故排除A、B两项。否定词not 已提前，故主句中为肯定句，故选D。句意为：直到半夜做完实验后他才回来。

②解析：选B。not until的倒装句型，用部分倒装，助动词提到主语之前，而且not已经移到句首，因此句中不能再出现，故选B。
