W: No, not at this level.
M: How about writing？ Is there anything on composition？

M: I see. And just a few more questions. Do you have a language lab where! can work on my pronunciation？ And what about videos and computers？
W: Well, we don't have a language lab. The building is too small. But we do have video and we also have tape recorders in every room.
M: And computers？
W: No, none at present.
M: I see. Well, thank you very much. You're very helpful.
W: You're welcome. Good-bye.
