这些时态都可以用： 　When are you going to Spain? (未来) 　When will you get a job? (未来) 　When did you see that movie? (过去) 　When do you (usually) have dinner? (习惯) 　When do you go on holidays? ([口语]未来) 　(Since) when have you been to Spain? ([since when 带着怀疑]现在完成) 　在这种疑问句子里，过去完成式和未来完成式比较难用：When will you have been to Spain? (未来完成) 这个时态本来就很少用，对于以英语为母语的人来说，When will you have been to Spain? 可能会显得非常不自然。
