题目

He told me with regret that his truck which had been out of control at the sharp bend.这句子哪里错
为什么?

答案

句子不不完整
that后面是说的内容,但是which后面的都是修饰his truck的,
也就是说,说的内容只有his truck?!
句子翻译一下：他很遗憾地对我说,他的那辆在弯道失控了的大卡车.（大卡车怎么样了?）
应该是He told me with regret that his truck had been out of control at the sharp bend.他很遗憾地告诉我说,他的那辆大卡车在弯道失控了
去掉which就行了,这类题就看分析成分~
