sat语法旧版og第一套 Linguistic research often requires fieldwork where they can study and record the spoken dialects of a region. where they划线改成during which the linguist 为什么不能改成which they
定语从句修饰fieldwork,如果用which来引导,那么fieldwork必定在后面定语从句中担任主语或宾语,但是定语从句中的主语是they,宾语也有是 the spoken dialects of a region,因此fieldwork只能放在定语从句作状语用during the field. 再者,they指代不明,要明确说出the linguists. 所以改成during which the linguists.
