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.

河边有许多树。

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”:

He told me he would come again later (on).

他告诉我他以后会再来的。

I met her again a few days later.

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:

I met him right here.

我就是在这里见到他的。

He hit the man right on the nose.

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:
