新概念英第二册：第 7 文解及法解析文注 Further notes on the text1. ⋯ detectives were waiting at the airport allmorning. 探在机等了⋯⋯整整一上午。

all 一般直接加表示的数名构成副短，如：allday (整整一天 )，all night(整夜 )， all week(整星期 )，allwinter( 整个冬天 )，all year(整年 )等。

但不 all hour。

whole 在表达同的意思一般要加冠或数，如： a wholeday/ year(一整天 / 年)，two whole weeks(整整两星期 )。

2.⋯ someone had told the police that thieves would tryto steal the diamonds. ⋯⋯有人向警方告，有人企走些石。

that 后面的部分 tell 的从句。

从句中的去将来(would)。

3.When the plane arrived, some of the detectives werewaiting inside the main building while others were waiting onthe airfield. 当机到达，一些探等候在主楼内，另一些探守候在停机坪上。

(1)个句子由 3 个部分成： when 引的是整个句子的状从句;some of ⋯building主句 ;while 引的是作与主句的作同行的状从句。

while 作表示“和⋯⋯同”、“当⋯⋯候” 常常引一个去行从句。

(cf.本法 )(2)地点状on the airfield 与第一句中的 at the airport意相近。

注意介 on 和 at 的不同搭配。

(3)代 others 常常和 some 用，表示“有些(人) ⋯⋯，也有些 (人) ⋯⋯”或者“有的⋯⋯，其余的⋯⋯”：Some students are very hard-working, others are not.有些学生非常用功，有些不然。
