英语语法 where
The helicopter has now become an extremely useful machine.It excels in military missions,carrying troops,guns and strategic instruments where other aircraft cannot go
为什么这里用where 而不用which啊
答
这是定语从句,句中缺关系副词你这样说，我更不懂了，你能耐心跟我讲讲吗？是不是other aircraft cannot go 完整 所以用 whereother aircraft cannot go 句子不缺宾语，缺表示地点的状语，所以用 where
