during which与during which time的异同
在学习定语从句时,许多同学对during which和during which time的用法混淆不清,认为它们没有什么区别,甚至认为during which time中的time是多余的。其实,during which和during which time在用法上是不一样的。现归纳如下:
during which的用法
during which相当于during the time/the period/the course of ...,既可用于限制性定语从句,也可用于非限制性定语从句;可指时间,也可指过程或阶段等。意为“在……期间,在……过程中,在……阶段”等。
1. during which 用于限制性定语从句时,修饰对象为先行词,先行词在定语从句中表示“在……期间,在……过程中”。例如:
September and October are the months of the year during which most English people take their holidays.
一年中9、10两个月是大多数英国人休假的月份。
点拨句中的during which = and during the time of the months of the year,表示“一年中的这两个月间”。
In 1988, Vietnam and china fought a brief naval battle during which more than 70 Vietnamese sailors died.
1988年,越南和中国曾进行过一次小规模海战,70多名越南士兵在战斗中丧生。

点拨句中的during which = and during the course of the brief naval battle,表示“小规模海战期间”。
2. during which 用于非限制性定语从句时,不修饰整个句子,只修饰句子中的某个词(组),被修饰的词(组),在从句中表“在……期间,在……过程中”。例如:
She kept her vow for a week, during which she was unusually cross and fretful.
她信守誓言有一星期之久,但在这一星期内,她显得五心烦躁,动不动就发脾气。
点拨句中的during which=and during the time of the week,表示“在这一星期期间”。
He died in the Anti-Japanese War, during which my grandfather fought side by side with him.
他在抗日战争中为国捐躯,在抗战期间,我祖父曾与他并肩战斗过。
点拨句中的during which=and during the period of the Anti-Japanese War,表示“在抗日战争期间”。
