Question

I was with him one afternoon when,never exceeding the speed limits,be made it..exceed为什么加ING
without catching a single red light.,never不是介词,插入语也要看主谓么?

Answer 1

I was with him one afternoon when,never exceeding the speed limits,he made it without catching a single red light.
never exceeding the speed limits最好不要看做是插入语.这句话实际上是状语成分,修饰he made it without catching a single red light.
Exceed的动作发出者是he,所以使用现在分词形式.这个语法现象叫做现在分词做伴随状语.之所以用逗号隔开,是因为这个伴随状语修饰的是句子中的从句,所以它必须出现在引导从句的when后面,以表明它修饰从句而不是主句；但它又不是不能和when顺序相接的,为避免读者误认为when和never 是自然连接,必须用逗号隔开.
