可改写为： I happened to hear their secret.
我碰巧听到了他们的秘密。
22. It's/has been +一段时间+since从句 自从某时起做某件事情已经一段时间了
该句型中since引导的时间状语从句常用一般过去时。例如：

sth。例如：

It's a good idea for us to travel to the
south.
去南方旅行对我们来说是个好主意。
24. It's + adj. + of sb. to do sth.
It是形式主语，to do sth.是真正的主语, 当表语(即形容词)能对逻辑主语描述时，常用介词of,而不用for。例如：
It's very polite of you to give your seat
to old people.
你给老人让座，非常有礼貌。

end.

it是形式主语，真正的主语是动词不定式to
do sth. 例如：

比较下面两种结构：

29. keep (on) doing sth. 一直坚持做某事
keep doing sth.一般用于静态动词。keep
on doing sth.意为“继续不停地做某事”，一般用于动态动词，但二者的区别并不是很严格，有时可以互换。例如：

不要再做这样的傻事了。

make意为“使”时，其后要有不带to的动词不定式。例如：

他让我每天工作10小时。
注意：上句如改为被动语态，则work 前的to不能省略。例如：
I was made to work ten hours a day.
33. neither…nor… 既不……也不……
当连接两个并列主语时，谓语动词与邻近的主语取得一致(就进一致原则)。例如：
Neither we nor Jack knows him.
我们和杰克都不认识他。
He neither knows nor cares what happened.
他对发生的事情不闻不问。
34. not…until… 直到……才......

yesterday. 昨晚我花了两个小时做作业。

it.
冰太薄了，你不能在上面走。
