新概念英语 两句 as soon as
新概念英语第二册
lesson 14 Do you speak English?
As soon as he had got into the car,I said good morning to him in french.
Lesson 27 A wet night
As soon as this was done,they cooked a meal over an open fire.
Lesson 42 Not very musical
As soon as he saw us,he picked up a long pipe which covered with coins and opened one of the baskets.
为什么第14课的As soon as 前面用过去完成时,而其他的用一般过去是呢?27,42课是否可以改成过去完成时呢?

14课的那个人从他上车到进到车子里的过程中那个“I”说的good morning ,视为那个动作是延续的
27课的课文我查了一下,前边你没写的那句是他们搭了帐篷,而他们做饭的时候,搭帐蓬的动作已经终止了,所以不能用完成时
42课的那个也是,see的动作不是延续的,
完成式和过去式的区别就在于完成式的动作有个延续,持续一小段时间,而过去式只能是一个点

(供参考^&^)
get 是延续性动词,
而be动词和see都是瞬间动词,过去了就过去了。
延续性动词表示能够延续的动作,这种动作可以延续下去或产生持久影响。如:learn, work, stand, lie, know, walk, keep, have, wait, watch, sing, read, sleep, live, stay等。
