重点句型
1.I was fast asleep when suddenly my bed began shaking and I heard a strange sound,like a railway train passing my window.
我睡得正酣，正在这时我的床开始晃动，我听到一种奇怪的声音，就像一列火车正从我窗外驶过。

when引导了时间状语从句在此状语从句中，and连接两个并列的句子like a railway train passing my window为介词短语作定语，修饰sound,而a railway train passing my window为like 的复合宾语。
"be+形容词/表示状态的介词短语+when..."表示“正在做某事，就在这时...”
be about to do sth when...正要做某事就在这时....
be doing+when...   正在做某事就在这时...
(分句中的动作往往是短暂性的）
had jsut done when...   刚做过某事，就在这时....
[温馨提示]
此时的when不可以与while互换，也不可以将when引导的从句置于句首
I was fast asleep when suddenly there was a loud noise outside my room.
我睡得正香，就在这时房外传来巨大的噪音。
He was on a journey there when he received her call.
他正在去那儿的旅行中，就在这时他接到了她的电话。

句中的this being my first experience为独立主格结构
独立主格结构（Absolute Structure)是由名词或代词加上分词等构成的一种独立结构，用于修饰整个句子独立主格结构中的名词或代词与其后的分词等构成逻辑上的主谓关系这种结构与主句不发生句法上的联系，它的位置相当灵活，可置于主句前、主句末或主句中，常由逗号将其与主句分开需要特别注意的是，独立主格结构与主句不能使用任何连接词。
独立主格结构基本构成形式为：
n.+v-ing/v-ed/adj./adv./to do/n./介词短语
Night enshrouding the earth,nobady could make out what it was from a distance.
黑夜笼罩大地，谁也看不清它是什么东西。
