Mary: This is a lovely room, Jane.

Jane: I`m glad you like it. It is always a pleasure to sit here and read magazines and newspapers after a long day in the office. And where do you live in St. Petersburg,  Mary?

Mary: We live in a four-room flat in a new district of St. Petersburg.

Jane: Is your flat comfortable?

Mary: Yes, it is very comfortable. There is very much built-in furniture in our hall and in the kitchen. Our windows are large and the rooms are light.

Jane: In which room do you like to spend evening hours?

Mary: I like to spend my evening hours in the sitting-room. We usually watch television there or listen to music on the records.

Jane: Yes, it is always nice to spend a quiet evening with the family.

Mary: I think so too.

Bill: I hate winter so much. I am tired. I could sleep like a bear and wake up in spring.
Mary: Well, I don't like spring. But I'd rather fly like a bird to a nice south country and spend winter there.
Bill: Yes, that might be a /good/ idea.
Mary: Be careful, Bill! We nearly fell into that ditch! It's really difficult to drive accurately when the weather is so bad. We aren't in a village.
But I am driving slow, Mary. Don't be stupid. You're really safe with me. In spring we'll be back again.

В общем, можно пропробовать так. хотя диалог ужасно тупой получается))
/good/ - вы не написали многоточие, но мне кажется там тоже пропущено слово. к тому же с idea должен идти артикль an, а не a как у вас. из этого я сделал вывод, что пропущено слово ещё одно.
