W: Morning, Mr Woo. What can I do for you? 

M: Alison, some Chinese visitors will come to our school tomorrow. 

W: What can I do to help you? 

M: Well. The problem is that I can’t speak any Chinese. Can you?

W: Yes. I studied it at college. My sister, Linda, can also speak Chinese well. 

M: Wonderful! Who will be free, you or your sister? 

W: Both of us. 

M: Thank you so much, Alison.
