二、原文

The plane was late and detectives were waiting at the airport all morning. They were expecting a valuable parcel of diamonds from South Africa. A few hours earlier, someone had told the police that thieves would try to steal the diamonds. When the plane arrived, some of the detectives were waiting inside the main building while others were waiting on the airfield. Two men took the parcel off the plane and carried it into the Customs House. While two detectives were keeping guard at the door, two others opened the parcel. To their surprise, the precious parcel was full of stones and sand!

三、课文和语法

1. The plane was late(一般过去式) and detectives were waiting（过去进行时） at the airport all morning.

at the airport 在机场   在某一个地点用at

2. They were expecting① a valuable parcel of diamonds from South Africa.

① 过去进行时

3. 过去进行时: 表示过去某一时刻正在发生的动作，常与时间状语从句或过去某个时间点连用。

1) 形式： was/were + doing

She was reading a book at 11:00 last night.

2)用法：

①用来描述过去特定的时刻正在发生的事情

②过去进行时还常常和一般过去式搭配使用，此时，过去进行时通常表示一个历时较长的体现“背景”的动作或状态；而一般过去时则表示此“背景”下发生的、短暂的动作或状态，过去进行时动作先发生，一般过去时动作后发生

I cut my finger when I was cooking the dinner last night.

3） 否定： was/were + not doing

She wasn’t reading a book at 11:00 last night.

4) Were/Was +主语+ doing…?

Was she reading a book at 11:00 last night?

5) 铺陈故事背景：一件事情持续进行，另一件事情把它打断。

While you were sleeping, a thief sneaked in.

4. A few hours earlier, someone had told the police that thieves would try to steal the diamonds.

try to do sth. 努力（尽力）做…(某人决心强烈)

try doing sth 尝试、试图做… (决心某那么强烈)

（1）had told 过去完成时

1)形式： had done

2)用法：过去的之前（不管全部完成还是部分完成）

Before 8:00 yesterday, she had finished her homework.

3) 否定： hadn’t done

4）疑问： Had + 主+ done +…?

5) 补充：过去完成时 vs 现在完成时

相同点：都是完成时（在一个时间点，看这个时间点之前事情的完成情况）

不同点：所处的时间点不同

It is 10:00, I have waited for 2 hours.

It was 10:00, I had waited for 2 hours.

6) 过去完成时VS一般过去时

相同点：.表过去的事情

不同点：一般过去时表过去的事情；过去完成时表过去的之前发生的事情。两者是一前一后发生的事情。

（2）would try 过去将来时

1）形式：would + do

 was/were going to do

2) 用法：过去的将来（过去一个时间点的将来）

He said he would go abroad next year.

(3) someone had told the police that thieves would try to steal the diamonds

tell sb sth

该句是复合句：主句+ 从句（这里是宾语从句）

宾语从句

1) 句子做宾语

2） 写法：

①陈述句变宾语从句

I think (that) you are right.

that 这里不做句子的成分，可省略

I think love is the greatest thing in the world.

5. When the plane arrived, some of the detectives were waiting inside the main building while others were waiting on the airfield.

1) when… while… 后面均接句子

while后面只接延续性动词，when都可以接

While you were sleeping, a thief sneaked in.

一件事情持续，另一件事情把它打断

2) some… others… 表示一些人… 另外一些人…

Some people are dancing in the park, others are taking a walk.

3) 与过去进行时搭配的时间状语从句连词有when, while, as, just as

as也引导持续性动作，但持续时间没有while那么长

When/As I left the house, I remembered the key.

6. Two men took the parcel off the plane and carried it into the Customs House.

take off 拿走/脱掉/起飞

很多动词加上介词或者副词构成短语后，词义会改变，判断一个动词后接的是介词还是副词，关键看宾语的位置。有宾语的是介词，没宾语的是副词

vt.+adv.+n. 或者vt.+n./pron.+adv.

vi.+prep.+n./pron.

take off my coat  take my coat off     take it off

look for my coat  look for it

7. While two detectives were keeping guard at the door …

keep guard 站岗、守卫

at the door 在门口， at +地点 常指某地方的附近

8. To their surprise, the precious parcel was full of stones and sand.

to one’s surprise 让某人惊讶

be full of 装满了

9. When = just as

When she was shutting the door, the baby woke up.

= Just as she was shutting the door, the baby woke up.

四、习惯用法

all morning

a parcel of sth.

A few hours earlier

to sb.’s surprise

try to do sth.

A be full of B
