1. " What colour of cars/ a car do you like ?" 正确. " What colour do you like for a car/ cars?“　正确.其实用Which 也是可以的.如果用Which（哪个）,就表示你是有一个范围的.比如说十二种颜色中的一种. 2. "...嗯。谢谢哈。 1“ 她离婚的 理由 / 原因 是什么？” 2恐龙灭亡的原因是什么？ 这个英语翻译。谢谢1. " For what reason did she divorce ?" " Why did she divorce ?" 2." What (are the reasons that) have caused the perish of dinosaurs?" " Why were the dinosaurs wiped out from the earth?"" For what reason did she divorce ?"这句前面 为什么加for ， 是不是 what reason did she divorce for ?提到前面了 ？for what reason = why for在这里表示“出于.... / 由于...."(何种原因）哦。谢谢明白了。呵呵What reason did she divorce for ?如果我这么写，语法上来说错误不？离婚的原因，我就是想要一个 what 开头的疑问句。呵呵。多谢啦你说的太好了，这样也是正确的！
