When changing lanes, a driver should use his turning signal to let other drivers know___.
A, he is entering which lane
B, which lane he is entering
答案B
请问A,语法上哪里有错呢?let other drivers know (that) he is entering which lane.
请问B中的which是做形容词修饰名词lane,然后整个做从句的宾语吗?可是如果which是做形容词怎么引导know的宾语从句?
转向灯为indecator, 不是turning signal。
which 为疑问限定词,限定名词。传统语法把which分析为疑问形容词,作定语修饰名词。特殊疑问句为Which lane are you entering? 疑问限定词which与名词lane构成疑问短语,疑问短语必须前置,引导疑问句。这是问句的结构决定的。当问句用作名词性从句时,仍然需要疑问短语前置引导问句,不同的是问句不再倒装,而用自然语序,同时删去问号。所以你的句子中,know的宾语是个名词性疑问分句,该分句必须由疑问短语引导问句,即which lane必须在问句之首。
