M: Hello, Jenny, you look so tired. How did you spend your weekend?
W: Oh, I went to visit my grandparents yesterday.
M: Really? It’d been a long time since you saw them last time, hadn’t it?
W: Yes, they’re weaker and more fragile than what I saw them last time.
M: They’re well pensioned off, aren’t they?
W: Yes, but money isn’t everything. (19)I’m pessimistic about the future of the aged. I don’t think they will be taken good care of by their families or the community. They may often feel lonely.
M: I think the opposite is true. (20)I am optimistic about the future of the aged. I am confident that the aged in our country are and will be well attended. It is certain that they will live a happy life.
W: But, you know, the aged have very special needs and they may have difficulty in health care, nutrition and housing, etc.
M: You are right in a way. But in general, I don’t think you need to worry about that. There are many rest homes for them.
W: There is another problem. The family planning policy encourages each couple to have only one child. This means a middle-aged couple will have to support four old people and one child. It is really a heavy burden for them, isn’t it?
M: Yes, but don’t be so nervous about it. The government on all levels has been sparing no effort to improve the current situation.
W: I hope so.
