飞机误点了, 侦探们在机场等了整整一上午. 他们正期待从南非来的一个装着钻石的贵重包裹. 数小时以前, 有人向警方报告, 说有人企图偷走这些钻石. 当飞机到达时, 一些侦探等候在主楼内, 另一些侦探则守候在停机坪上. 有两个人把包裹拿下飞机, 进了海关. 这时两个侦探把住门口, 另外两个侦探打开了包裹. 令他们吃惊的是, 那珍贵的包裹里面装的全是石头和沙子!

【新概念英语第二册7课文讲解】
1、The plane was late and detectives were waiting at the airport all morning.
all一般直接加表示时间的单数名词构成副词短语，如：all day，all night，all week，all winter，all year等。但不说all hour。
whole在表达同样的意思时一般要加冠词或数词，如a whole day/year，two whole weeks。
all morning=all the morning

The plane was late 飞机晚(点)了
The bus was late./The train was late.
detectives 没有强调一些侦探或者那些侦探, 强调侦探这种人，笼统感念, 可不加some, the

2、They were expecting a valuable parcel of diamonds from South Africa.
a valuable parcel of diamonds
a cup of tea 强调的是茶
South Africa 南非

3、A few hours earlier, someone had told the police that thieves would try to steal the diamonds.
a few hours earlier 几个小时以前
= a few hours before/a few hours ago
would +do 过去将来时,间接方式, 转述, 站在过去看未来

4、When the plane arrived, some of the detectives were waiting inside the main building while others were waiting on the airfield.
代词others常常和some连用，表示“有些（人）……，也有些（人）……”或“有的……，其余的……”
one…the other…   一个……另一个……
some…others…    一些……另一些……
  Some students are very hard-working, others are not.
others=other+名词复数

5、Two men took the parcel off the plane and carried it into the Customs House.
take sth. off…=take sth. away from…
and carried it into…carried 表示看得很重
Customs House 海关

6、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!
…were keeping guard at the door, two others opened the parcel.
表面上是分工, 两个动作同时发生, 不是同时开始同时结束, 延续时间不一致, 长一点时间的动作用进行时态, 短时间的动作用过去时.
When someone knocked at the door, I was having dinner.
keep guard   守卫
  They kept a close guard over the thieves.
at the door   在门边(固定搭配)
two others=two other detectives

to one's surprise,让某人惊讶的是
To my surprise, the teacher was late.

根据课文第3-4行someone had told the police that thieves would try to steal the diamond 和第8-9行While two detectives were keeping guard at the door…，可以判断出b. to prevent a robbery 是正确答案，其他3个都不对。

选 c
根据课文最后一句话To their surprise, the precious parcel was full of stones and sand! 可以推测出c. didn’t prevent the robbery 是正确的答案。其他3个选择都不符合课文内容。

3. ______ were detectives waiting? At the airport.
a. Why        b. when         c. Where        d. What
选 c
从回答中可以看出，此问句是对地点发问，a. Why，b. When,，d. What 都不能针对地点提问，只有c. Where是问地点的，可以用At the airport 来回答，所以选c。

4. ______ were they expecting? A valuable parcel of diamonds .
a. Why        b. When         c. Where        d. What
选 d
这一句是针对动词宾语提问的，回答是用名词短语A valuable parcel of diamonds，a. Why，b. When，C. where 这几个疑问词都不能针对动词宾语（名词）提问的，只有d. What 可以对名词提问。

a. before       b. after          c. when          d. as soon as
选 a
前面句子是过去完成时（had told），表示在过去某一动作或情况发生之前完成的事情， “某人告诉警察……”这一事件定是在“飞机到达前”发生的。所以选a. before(在……之前)。

6. The detectives went into the building and waited ______.
a. in           b. into          c. inside          d. for
选 c
a. in后面需要有一个表示地点的名词，意思才完整；b. into在意思上讲不通；d. for后面需要有一个名词做宾语，意思才完整；只有c. inside（在里面）意思最完整，而且与前半句的动作went into the building相符合，所以选c。
