是病句What did you dolast holida为什么是病句没有特意加your 加了就的余了，明白了吗？那What did you do on your last holiday？是病句吗？What did you do on your last holiday不是病句，必须加on希望能采纳，谢谢了这是例句 What did you do on your holiday? 你假期中做什么？Where are you going on your holiday? 你打算去哪度假？Tell me what you did on your holiday. 告诉我你放假的时候做了什么。那老师为什么说on和last不能用在一起上面我说错了 What did you do on yourholiday 这样是对的 或者 What did you dolast holiday这样也是对的 但是 What did you do on your last holiday就是错的了用了on就不能用last，用了last就不能用on
