课文详注 Further notes on the text
1.…the boys put up their tent in the middle of a field.……孩子们在田野中央搭起了帐篷。
in the middle of表示“在……当中”、“在……中间”,既可以用于表示地理位置,又可以用于表示时间或在某个过程当中:
He heard someone shouting in the middle of the night.
午夜前后,他听到有人大声叫喊。
Mary was in the middle of reading when her aunt arrived.
玛丽的姑妈到达时,玛丽正在读书。
in the centre of(在……中部/中央)则一般用于表示地理位置:
Alice Spring is a small town in the centre of Australia.
艾利斯斯普林斯是澳大利亚中部的一个小镇。
2.…they cooked a meal over an open fire.……他们就在篝火上烧起了饭。
open fire指无遮盖的、没有围起来的火,如篝火、盆火等。
3.…they told stories and sang songs by the campfire.……(他们)就围在营火旁讲起了故事,唱起了歌。介词by表示“在……旁边”、“靠近”,通常指距离非常近:Come and sit by me.
过来靠我坐。
There are many trees by the river.

4.But some time later it began to rain.但过了一阵子,天下起雨来。
副词 later表示“后来”、“以后”、“过后”:

几天以后我又遇见了她。
5.The stream wound its way across the field and then flowed right under their tent! 那小溪弯弯曲曲穿过田野,然后正好从他们的帐篷底下流过去!
(1)wind表示“曲折而行”时,既可以是及物动词,又可以是不及物动词:
The car wound through the village.
汽车曲曲折折地穿过村子。
The river winds its way through this district.
这条河弯弯曲曲地流经这个地区。
(2)right在此处表示强调,意为“正好”、“恰恰”、“就”。这种用法多见于口语中:

他正好打中那人的鼻子。
语法 Grammar in use
一般过去时(cf.第3课语法)
在并列句中,各分句在时态上通常要保持一致。在叙述过去发生的事件时,动词基本上都用一般过去时,但有时也会出现过去完成时和过去进行时,它们的同时使用并不违反动词的“一致原则”:
They all leapt out of their sleeping bags and hurried outside. It was raining heavily and they found that a stream had formed in the field.
他们全都跳出睡袋,跑到外面。雨下得很大,他们发现地上已经形成了一条小溪。
由于一般过去时常常表示过去某个特定的时间发生的事件,因此,它常与when,where等疑问词连用。除了时间状语可以表示特定的时间之外,地点状语也可以暗示或包括特定的时间:
Where did you last see her?
你最近在什么地方见过她?
一般过去时与一般现在时在上下文中同时使用可以表示对比:
