  W: Cancelled, was it?

  M: Yes, they said it had engine trouble.

  M: No, it isn't that, but you see I've to help organize Jill's party tonight so I'm afraid I can't come to the show. Tell you what I thought? Why don't you come to the party instead?

  W: Can I? Do you think Jill would mind if I did?

  M: No. I'm sure she wouldn't. You have to bring a bottle of course, but it doesn't have to be expensive.

  W: I hope not! I'm completely broke! The first thing I'll have to do is get rid of these tickets in order to pay for some wine. Who do you think……oh, look, there's Professor Shrimp. He likes Shakespeare's plays. See if he would like the tickets.

  Text 10

  More than 200 people, mostly middle-school students and workers at a nearby construction side, fell violently ill after eating breakfast from a soybean milk shop on Saturday in Nanjing, and several dozens died.

  The shop supplies breakfast to the nearby boarding middle school, as well as selling food to walk-in customers Although it was the weekend many students were taking additional courses, and boarders stayed on the campus.

  The victims were sent to 10 local hospitals for emergency treatment. “It is really unbearable to see the young children dying right before my eyes and their parents crying desperately,” said one doctor at the rescue site. Another doctor said that conditions of most patients were basically stable.

  A father of a victim said that his daughter bought two rice cakes and ate most of them on her way to school. Soon she felt sick and collapsed. “Luckily, she vomited the stuff out on the-way to hospital. So the doctors said she was not among the seriously poisoned,” the father said.

  More than 500 medical specialists are helping in the rescue work and Public Sccurity authorities are still looking into the case.
