重點句型
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，正在這時我的床開始晃動，我聽到一種奇怪的聲音，就像一列火車正從我窗外駛過。

when引導了時間狀語從句在此狀語從句中，and連接兩個并列的句子like a railway train passing my window為介詞短語作定語，修飾sound,而a railway train passing my window為like 的復合賓語。
"be+形容詞/表示狀態(tài)的介詞短語+when..."表示“正在做某事，就在這時...”
be about to do sth when...正要做某事就在這時....
be doing+when...   正在做某事就在這時...
(分句中的動作往往是短暫性的）
had jsut done when...   剛做過某事，就在這時....
[溫馨提示]
此時的when不可以與while互換，也不可以將when引導的從句置于句首
I was fast asleep when suddenly there was a loud noise outside my room.
我睡得正香，就在這時房外傳來巨大的噪音。
He was on a journey there when he received her call.
他正在去那兒的旅行中，就在這時他接到了她的電話。

A When   B as   C while   D Then
考查“be about to do when..."的句型此結構的意思是”正要做某事，就在這時....”其中when相當于and just then,不可以用while,as 等替換
2....,but this being my first experience,I stayed at the top and watched them.
...我是第一次經歷這樣的事，所以留在山頂上觀察他們。

句中的this being my first experience為獨立主格結構
獨立主格結構（Absolute Structure)是由名詞或代詞加上分詞等構成的一種獨立結構，用于修飾整個句子獨立主格結構中的名詞或代詞與其后的分詞等構成邏輯上的主謂關系這種結構與主句不發(fā)生句法上的聯(lián)系，它的位置相當靈活，可置于主句前、主句末或主句中，常由逗號將其與主句分開需要特別注意的是，獨立主格結構與主句不能使用任何連接詞。
獨立主格結構基本構成形式為：
n.+v-ing/v-ed/adj./adv./to do/n./介詞短語
Night enshrouding the earth,nobady could make out what it was from a distance.
黑夜籠罩大地，誰也看不清它是什么東西。

3.Having taken the wrong bus,Martin found himself in an unfamiliar district.
