Lesson 19

Sold out

When will the writer see the play?

  'The play may begin at any moment,' I said.

  'It may have begun already,' Susan answered.

  I hurried to the ticket office. 'May I have two tickets please?' I asked.

  'I'm sorry, we've sold out,' the girl said.

  'What a pity!' Susan exclaimed.

  Just then, a man hurried to the ticket office.

  'Can I return these two tickets?' he asked.

  'Certainly,' the girl said.

  I went back to the ticket office at once.

  'Could I have those two tickets please?' I asked.

  'Certainly,' the girl said, 'but they're for next Wednesday's performance. Do you still want them?'

  'I might as well have them,' I said sadly.

疑问：but they're for next Wednesday's performance. 这句不是很懂，没有补充成分来说明介词短语for next Wednesday's performance的内容，意义不明。不知其为何这么写？

正常的不应该是“but they're two tickets to next Wednesday's performance.” 吗？
